class="card-text"><strong>Abstract:</strong></p> Nonlinear polarization rotation (NPR) technique has become one of the main techniques to achieve mode-locked fiber lasers for its compactness, implementation, and low cost. In this paper, we demonstrate a compact mode-locked Yb-doped fiber laser based on NPR technique in the all normal dispersion (ANDi) regime. In the laser cavity, there are no physical filter and polarization controller in laser cavity. Mode-locked pulse train is achieved in ANDi regime based on NPR technique. The fiber birefringence induced filtering effect is the mainly reason for mode-locking. After that, an extra 20 m long single-mode fiber is inserted in two different positions, dissipative soliton operation and noise like pulse operations are achieved correspondingly. The nonlinear effect is obviously enhanced in the noise like pulse regime and broadband spectrum generated owing to enhanced stimulated Raman scattering effect. When the pump power is 210 mW, the central wavelength is 1030 nm, and the corresponding 1st order Raman scattering stokes wave generates and locates at 1075 nm. When the pump power is 370 mW, the 1st and 2nd order Raman scattering stokes wave generate and locate at 1080 nm, 1126 nm respectively. When the pump power is 600 mW, the Raman continuum is generated with cascaded multi-order stokes waves, and the spectrum extends to 1188 nm. The total flat spectrum is from 1000nm to 1200nm. The maximum output average power and pulse energy are 18.0W and 14.75nJ, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fiber%20laser" title="fiber laser">fiber laser</a>, <a href="https://publications.waset.org/abstracts/search?q=mode-locking" title=" mode-locking"> mode-locking</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20polarization%20rotation" title=" nonlinear polarization rotation"> nonlinear polarization rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman%20scattering" title=" Raman scattering"> Raman scattering</a> </p> <a href="https://publications.waset.org/abstracts/74790/raman-scattering-broadband-spectrum-generation-in-compact-yb-doped-fiber-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">97</span> Bulk Transport in Strongly Correlated Topological Insulator Samarium Hexaboride Using Hall Effect and Inverted Resistance Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexa%20Rakoski">Alexa Rakoski</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun%20Suk%20Eo"> Yun Suk Eo</a>, <a href="https://publications.waset.org/abstracts/search?q=Cagliyan%20Kurdak"> Cagliyan Kurdak</a>, <a href="https://publications.waset.org/abstracts/search?q=Priscila%20F.%20S.%20Rosa"> Priscila F.

In the resistance-temperature curve, SmB6 exhibits activated behavior from 4-40 K after the Kondo gap forms. However, below 4 K, the resistivity is temperature independent or weakly temperature dependent due to the appearance of a topologically protected surface state. Current research suggests that the surface of SmB6 is conductive while the bulk is truly insulating, different from conventional 3D TIs (Topological Insulators) like Bi₂Se₃ which are plagued by bulk conduction due to impurities. To better understand why the bulk of SmB6 is so different from conventional TIs, this study employed a new method, called inverted resistance, to explore the lowest temperatures, as well as standard Hall measurements for the rest of the temperature range. In the inverted resistance method, current flows from an inner contact to an outer ring, and voltage is measured outside of this outer ring. This geometry confines the surface current and allows for measurement of the bulk resistivity even when the conductive surface dominates transport (below 4 K). The results confirm that the bulk of SmB6 is truly insulating down to 2 K. Hall measurements on a number of samples show consistent bulk behavior from 4-40 K, but widely varying behavior among samples above 40 K. This is attributed to a combination of the growth process and purity of the starting material, and the relationship between the high and low temperature behaviors is still being explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bulk%20transport" title="bulk transport">bulk transport</a>, <a href="https://publications.waset.org/abstracts/search?q=Hall%20effect" title=" Hall effect"> Hall effect</a>, <a href="https://publications.waset.org/abstracts/search?q=inverted%20resistance" title=" inverted resistance"> inverted resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Kondo%20insulator" title=" Kondo insulator"> Kondo insulator</a>, <a href="https://publications.waset.org/abstracts/search?q=samarium%20hexaboride" title=" samarium hexaboride"> samarium hexaboride</a>, <a href="https://publications.waset.org/abstracts/search?q=topological%20insulator" title=" topological insulator"> topological insulator</a> </p> <a href="https://publications.waset.org/abstracts/94303/bulk-transport-in-strongly-correlated-topological-insulator-samarium-hexaboride-using-hall-effect-and-inverted-resistance-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94303.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">96</span> A Preliminary Study of the Reconstruction of Urban Residential Public Space in the Context of the “Top-down” Construction Model in China: Based on Research of TianZiFang District in Shanghai and Residential Space in Hangzhou</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wang%20Qiaowei">Wang Qiaowei</a>, <a href="https://publications.waset.org/abstracts/search?q=Gao%20Yujiang"> Gao Yujiang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the economic growth and rapid urbanization after the reform and openness, some of China's fast-growing cities have demolished former dwellings and built modern residential quarters. The blind, incomplete reference to western modern cities and the one-off construction lacking feedback mechanism have intensified such phenomenon, causing the citizen gradually expanded their living scale with the popularization of car traffic, and the peer-to-peer lifestyle gradually settled. The construction of large-scale commercial centers has caused obstacles to small business around the residential areas, leading to space for residents' interaction has been compressed. At the same time, the advocated Central Business District (CBD) model even leads to the unsatisfactory reconstruction of many historical blocks such as the Hangzhou Southern Song Dynasty Imperial Street. However, the popularity of historical spaces such as Wuzhen and Hongcun also indicates the collective memory and needs of the street space for Chinese residents. The evolution of Shanghai TianZiFang also proves the importance of the motivation of space participants in space construction in the context of the “top-down” construction model in China. In fact, there are frequent occurrences of “reconstruction”, which may redefine the space, in various residential areas. If these activities can be selectively controlled and encouraged, it will be beneficial to activate the public space as well as the residents’ intercourse, so that the traditional Chinese street space can be reconstructed in the context of modern cities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rapid%20urbanization" title="rapid urbanization">rapid urbanization</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20street%20space" title=" traditional street space"> traditional street space</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20re-construction" title=" space re-construction"> space re-construction</a>, <a href="https://publications.waset.org/abstracts/search?q=bottom-up%20design" title=" bottom-up design"> bottom-up design</a> </p> <a href="https://publications.waset.org/abstracts/109105/a-preliminary-study-of-the-reconstruction-of-urban-residential-public-space-in-the-context-of-the-top-down-construction-model-in-china-based-on-research-of-tianzifang-district-in-shanghai-and-residential-space-in-hangzhou" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109105.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">115</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">95</span> Effects of Blood Pressure According to Age on End-Stage Renal Disease Development in Diabetes Mellitus Patients: A Nationwide Population-Based Cohort Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eun%20Hui%20Bae">Eun Hui Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Yeob%20Lim"> Sang Yeob Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Bongseong%20Kim"> Bongseong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Ryom%20Oh"> Tae Ryom Oh</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Hyun%20Song"> Su Hyun Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Heon%20Suh"> Sang Heon Suh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Sang%20Choi"> Hong Sang Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Mi%20Yang"> Eun Mi Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Seong%20Kim"> Chang Seong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Kwon%20Ma"> Seong Kwon Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Do%20Han"> Kyung-Do Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Soo%20Wan%20Kim"> Soo Wan Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Recent hypertension guidelines have recommended lower blood pressure (BP) targets in high-risk patients. However, there are no specific guidelines based on age or systolic and diastolic blood pressure (SBP and DBP, respectively). We aimed to assess the effects of age-related BP on the development of end-stage renal disease (ESRD) in patients with diabetes. Methods: A total of 2,563,870 patients with DM aged >20 years were selected from the Korean National Health Screening Program from 2009 to 2012 and followed up until the end of 2019. Participants were categorized into age and BP groups, and the hazard ratios (HRs) for ESRD were calculated. Results: During a median follow-up of 7.15 years, the incidence rates of ESRD increased with increasing SBP and DBP. The HR for ESRD was the highest in patients younger than 40 years of age with DBP ≥ 100 mmHg. The effect of SBP and DBP on ESRD development was attenuated with age (interaction p-value was <0.0001 for age and SBP and 0.0022 for age and DBP). The subgroup analysis for sex, anti-hypertension medication, and history of chronic kidney disease (CKD) showed higher HRs for ESRD among males younger than 40 years, not taking anti-hypertension medications and CKD compared to those among females older than 40 years, anti-hypertension medication and non-CKD groups. Conclusions: Higher SBP and DBP increase the risk of developing ESRD in patients with diabetes, and in particular, younger individuals face greater risk. Therefore, intensive BP management is warranted in younger patients to prevent ESRD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypertension" title="hypertension">hypertension</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20adult" title=" young adult"> young adult</a>, <a href="https://publications.waset.org/abstracts/search?q=end-stage%20renal%20disease" title=" end-stage renal disease"> end-stage renal disease</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title=" diabetes mellitus"> diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20kidney%20disease" title=" chronic kidney disease"> chronic kidney disease</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20pressure" title=" blood pressure"> blood pressure</a> </p> <a href="https://publications.waset.org/abstracts/149411/effects-of-blood-pressure-according-to-age-on-end-stage-renal-disease-development-in-diabetes-mellitus-patients-a-nationwide-population-based-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149411.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">94</span> Prompt Design for Code Generation in Data Analysis Using Large Language Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lu%20Song%20Ma%20Li%20Zhi">Lu Song Ma Li Zhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid advancement of artificial intelligence technology, large language models (LLMs) have become a milestone in the field of natural language processing, demonstrating remarkable capabilities in semantic understanding, intelligent question answering, and text generation. These models are gradually penetrating various industries, particularly showcasing significant application potential in the data analysis domain. However, retraining or fine-tuning these models requires substantial computational resources and ample downstream task datasets, which poses a significant challenge for many enterprises and research institutions. Without modifying the internal parameters of the large models, prompt engineering techniques can rapidly adapt these models to new domains. This paper proposes a prompt design strategy aimed at leveraging the capabilities of large language models to automate the generation of data analysis code. By carefully designing prompts, data analysis requirements can be described in natural language, which the large language model can then understand and convert into executable data analysis code, thereby greatly enhancing the efficiency and convenience of data analysis. This strategy not only lowers the threshold for using large models but also significantly improves the accuracy and efficiency of data analysis. Our approach includes requirements for the precision of natural language descriptions, coverage of diverse data analysis needs, and mechanisms for immediate feedback and adjustment. Experimental results show that with this prompt design strategy, large language models perform exceptionally well in multiple data analysis tasks, generating high-quality code and significantly shortening the data analysis cycle. This method provides an efficient and convenient tool for the data analysis field and demonstrates the enormous potential of large language models in practical applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=large%20language%20models" title="large language models">large language models</a>, <a href="https://publications.waset.org/abstracts/search?q=prompt%20design" title=" prompt design"> prompt design</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20analysis" title=" data analysis"> data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=code%20generation" title=" code generation"> code generation</a> </p> <a href="https://publications.waset.org/abstracts/188761/prompt-design-for-code-generation-in-data-analysis-using-large-language-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188761.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">39</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">93</span> Deubiquitinase USP35 Regulates Mitosis Progression by Blocking CDH1-Mediated Degradation of Aurora B.</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinyoung%20Park">Jinyoung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Joo%20Song"> Eun Joo Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Deubiquitinating enzymes (DUBs) are proteases that cleave ubiquitin or ubiquitin-like modifications on substrates. Deubiquitination could regulate cellular physiology, such as signal transduction, DNA damage and repair, and cell cycle progression. Although more than 100 DUBs are encoded in the human and the importance of DUBs has been realized, the functions of most DUBs are unknown. This study aims to identify the molecular mechanism by which deubiquitinating enzyme USP35 regulates cell cycle progression for the first time. Methods: USP35 RNAi was mainly used to identify the function of USP35 in cell cycle progression. To find substrates of USP35, we analyzed protein-protein interaction using LC-MS. Several biological methods, such as ubiquitination assay, cell synchronization, immunofluorescence, and immunoprecipitation assay were used to investigate the exact mechanism by which USP35 affects successful completion of mitosis. Results: USP35 knockdown caused not only reduction of mitotic cell number but also induction of mitotic cells with abnormal spindle formation. Actually, cell proliferation was decreased by USP35 knockdown. Interestingly, we found that loss of USP35 decreased the stability and expression of Aurora B, a member of chromosomal passenger complex (CPC), and the phosphorylation of its substrate. Indeed, USP35 interacted with Aurora B and deubiquitinated it. In addition, USP35 knockdown induced abnormal localization of Aurora B in mitotic cells. Finally, CDH1-mediated ubiquitination of Aurora B level was rescued by USP35 overexpression, but not inactive form of USP35, USP35 C450A. Discussion: Our findings suggest that USP35 regulates Aurora B-mediated mitotic spindle assembly and G2-M transition by blocking CDH1-induced degradation of Aurora B. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=USP35" title="USP35">USP35</a>, <a href="https://publications.waset.org/abstracts/search?q=HSP90" title=" HSP90"> HSP90</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurora%20B" title=" Aurora B"> Aurora B</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20cycle%20progression" title=" cell cycle progression"> cell cycle progression</a> </p> <a href="https://publications.waset.org/abstracts/30553/deubiquitinase-usp35-regulates-mitosis-progression-by-blocking-cdh1-mediated-degradation-of-aurora-b" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30553.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">358</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">92</span> The Use of Themes and Variations in Early and Contemporary Juju Music</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olupemi%20E.%20Oludare">Olupemi E.

It examines the use of themes and variations in early and contemporary Juju music. The work is an outcome of a research developed by the author in his doctoral studies at the University of Lagos, Nigeria, with the aim of analyzing the thematic and motivic developments in Yoruba popular genres. Observations, interviews, live recordings and CDs were used as methods for eliciting information. Field recordings and CDs of selected musical samples were also transcribed and notated. The research established the prevalent use of string of themes by Juju musicians as a compositional technique in moving from one musical section to another, as they communicate the verbal messages in their song. These themes consisting of the popular ‘call and response’ form found in most African music, analogous to the western ‘subject and answer’ style of the fugue or sonata form, although without the tonic–dominant relations. Due to the short and repetitive form of African melodies and rhythms, a theme is restated as a variation, where its rhythmic and melodic motifs are stylistically developed and repeated, but still retaining its recognizable core musical structure. The findings of this study showed that Juju musicians generally often employ a thematic plan where new themes are used to arrange the songs into sections, and each theme is developed into variations in order to further expand the music, eliminate monotony, and create musical aesthetics, serving as hallmark of its musical identity. The study established the musical and extra-musical attributes of the genre, while recommending further research towards analyzing the various compositional techniques employed in African popular genres. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compositional%20techniques" title="compositional techniques">compositional techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=popular%20music" title=" popular music"> popular music</a>, <a href="https://publications.waset.org/abstracts/search?q=theme%20and%20variation" title=" theme and variation"> theme and variation</a>, <a href="https://publications.waset.org/abstracts/search?q=thematic%20development" title=" thematic development"> thematic development</a> </p> <a href="https://publications.waset.org/abstracts/32009/the-use-of-themes-and-variations-in-early-and-contemporary-juju-music" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32009.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">412</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">91</span> Another Beautiful Sounds: Building the Memory of Sound of Peddling in Beijing with Digital Technology </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dan%20Wang">Dan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qing%20Ma"> Qing Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaodan%20Wang"> Xiaodan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Tianjiao%20Qi"> Tianjiao Qi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The sound of peddling in Beijing, also called “yo-heave-ho” or “cry of one's ware”, is a unique folk culture and usually found in Beijing hutong. For the civilians in Beijing, sound of peddling is part of their childhood. And for those who love the traditional culture of Beijing, it is an old song singing the local conditions and customs of the ancient city. For example, because of his great appreciation, the British poet Osbert Stewart once put sound of peddling which he had heard in Beijing as a street orchestra performance in the article named "Beijing's sound and color".This research aims to collect and integrate the voice/photo resources and historical materials of sound concerning peddling in Beijing by digital technology in order to protect the intangible cultural heritage and pass on the city memory. With the goal in mind, the next stage is to collect and record all the materials and resources based on the historical documents study and interviews with civilians or performers. Then set up a metadata scheme (which refers to the domestic and international standards such as "Audio Data Processing Standards in the National Library", DC, VRA, and CDWA, etc.) to describe, process and organize the sound of peddling into a database. In order to fully show the traditional culture of sound of peddling in Beijing, web design and GIS technology are utilized to establish a website and plan holding offline exhibitions and events for people to simulate and learn the sound of peddling by using VR/AR technology. All resources are opened to the public and civilians can share the digital memory through not only the offline experiential activities, but also the online interaction. With all the attempts, a multi-media narrative platform has been established to multi-dimensionally record the sound of peddling in old Beijing with text, images, audio, video and so on. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sound%20of%20peddling" title="sound of peddling">sound of peddling</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=metadata%20scheme" title=" metadata scheme"> metadata scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=VR%2FAR%20technology" title=" VR/AR technology"> VR/AR technology</a> </p> <a href="https://publications.waset.org/abstracts/64302/another-beautiful-sounds-building-the-memory-of-sound-of-peddling-in-beijing-with-digital-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64302.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">304</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">90</span> Enhancement of Mechanical and Dissolution Properties of a Cast Magnesium Alloy via Equal Angular Channel Processing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tim%20Dunne">Tim Dunne</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiaxiang%20Ren"> Jiaxiang Ren</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Zhao"> Lei Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Peng%20Cheng"> Peng Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20Song"> Yi Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Liu"> Yu Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenhan%20Yue"> Wenhan Yue</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiongwen%20Yang"> Xiongwen Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two decades of the Shale Revolution has transforming transformed the global energy market, in part by the adaption of multi-stage dissolvable frac plugs. Magnesium has been favored for the bulk of plugs, requiring development of materials to suit specific field requirements. Herein, the mechanical and dissolution results from equal channel angular pressing (ECAP) of two cast dissolvable magnesium alloy are described. ECAP was selected as a route to increase the mechanical properties of two formulations of dissolvable magnesium, as solutionizing failed. In this study, 1” square cross section samples cast Mg alloys formulations containing rare earth were processed at temperatures ranging from 200 to 350 °C, at a rate of 0.005”/s, with a backpressure from 0 to 70 MPa, in a brass, or brass + graphite sheet. Generally, the yield and ultimate tensile strength (UTS) doubled for all. For formulation DM-2, the yield increased from 100 MPa to 250 MPa; UTS from 175 MPa to 325 MPa, but the strain fell from 2 to 1%. Formulation DM-3 yield increased from 75 MPa to 200 MPa, UTS from 150 MPa to 275 MPa, with strain increasing from 1 to 3%. Meanwhile, ECAP has also been found to reduce the dissolution rate significantly. A microstructural analysis showed grain refinement of the alloy and the movement of secondary phases away from the grain boundary. It is believed that reconfiguration of the grain boundary phases increased the mechanical properties and decreased the dissolution rate. ECAP processing of dissolvable high rare earth content magnesium is possible despite the brittleness of the material. ECAP is a possible processing route to increase mechanical properties for dissolvable aluminum alloys that do not extrude. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=equal%20channel%20angular%20processing" title="equal channel angular processing">equal channel angular processing</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolvable%20magnesium" title=" dissolvable magnesium"> dissolvable magnesium</a>, <a href="https://publications.waset.org/abstracts/search?q=frac%20plug" title=" frac plug"> frac plug</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a> </p> <a href="https://publications.waset.org/abstracts/132877/enhancement-of-mechanical-and-dissolution-properties-of-a-cast-magnesium-alloy-via-equal-angular-channel-processing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132877.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">116</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">89</span> Analysis of Factors Influencing the Response Time of an Aspirating Gaseous Agent Concentration Detection Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu%20Guan">Yu Guan</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%20Lu"> Song Lu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Yuan"> Wei Yuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Heping%20Zhang"> Heping Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gas fire extinguishing system is widely used due to its cleanliness and efficiency, and since its spray will be affected by many factors such as convection and obstacles in jetting region, so in order to evaluate its effectiveness, detecting concentration distribution in the jetting area is indispensable, which is commonly achieved by aspirating concentration detection technique. During the concentration measurement, the response time of detector is a very important parameter, especially for those fire-extinguishing systems with rapid gas dispersion. Long response time will not only underestimate its concentration but also prolong the change of concentration with time. Therefore it is necessary to analyze the factors influencing the response time. In the paper, an aspirating concentration detection method was introduced, which is achieved by using a small critical nozzle and a laminar flowmeter, and because of the response time is mainly related to the gas transport process from sampling site to the sensor, the effects of exhaust pipe size, gas flow rate, and gas concentration on its response time were analyzed. During the research, Bromotrifluoromethane (CBrF₃) was used. The effect of the sampling tube was investigated with different length of 1, 2, 3, 4 and 5 m (5mm in pipe diameter) and different pipe diameter of 3, 4, 5, 6 and 8 mm (3m in length). The effect of gas flow rate was analyzed by changing the throat diameter of the critical nozzle with 0.5, 0.682, 0.75, 0.8, 0.84 and 0.88 mm. The effect of gas concentration on response time was studied with the concentration range of 0-25%. The result showed that the response time increased with the increase of both the length and diameter of the sampling pipe, and the effect of length on response time was linear, but for the effect of diameter, it was exponential. It was also found that as the throat diameter of critical nozzle increased, the response time reduced a lot, in other words, gas flow rate has a great influence on response time. For the effect of gas concentration, the response time increased with the increase of the CBrF₃ concentration, and the slope of the curve was reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aspirating%20concentration%20detection" title="aspirating concentration detection">aspirating concentration detection</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20extinguishing" title=" fire extinguishing"> fire extinguishing</a>, <a href="https://publications.waset.org/abstracts/search?q=gaseous%20agent" title=" gaseous agent"> gaseous agent</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20time" title=" response time"> response time</a> </p> <a href="https://publications.waset.org/abstracts/74810/analysis-of-factors-influencing-the-response-time-of-an-aspirating-gaseous-agent-concentration-detection-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74810.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">270</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">88</span> Collapse Analysis of Planar Composite Frame under Impact Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lian%20Song">Lian Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao-Bo%20Kang"> Shao-Bo Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Yang"> Bo Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Concrete filled steel tubular (CFST) structure has been widely used in construction practices due to its superior performances under various loading conditions. However, limited studies are available when this type of structure is subjected to impact or explosive loads. Current methods in relevant design codes are not specific for preventing progressive collapse of CFST structures. Therefore, it is necessary to carry out numerical simulations on CFST structure under impact loads. In this study, finite element analyses are conducted on the mechanical behaviour of composite frames which composed of CFST columns and steel beams subject to impact loading. In the model, CFST columns are simulated using finite element software ABAQUS. The model is verified by test results of solid and hollow CFST columns under lateral impacts, and reasonably good agreement is obtained through comparisons. Thereafter, a multi-scale finite element modelling technique is developed to evaluate the behaviour of a five-storey three-span planar composite frame. Alternate path method and direct simulation method are adopted to perform the dynamic response of the frame when a supporting column is removed suddenly. In the former method, the reason for column removal is not considered and only the remaining frame is simulated, whereas in the latter, a specific impact load is applied to the frame to take account of the column failure induced by vehicle impact. Comparisons are made between these two methods in terms of displacement history and internal force redistribution, and design recommendations are provided for the design of CFST structures under impact loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=planar%20composite%20frame" title="planar composite frame">planar composite frame</a>, <a href="https://publications.waset.org/abstracts/search?q=collapse%20analysis" title=" collapse analysis"> collapse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20loading" title=" impact loading"> impact loading</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20simulation%20method" title=" direct simulation method"> direct simulation method</a>, <a href="https://publications.waset.org/abstracts/search?q=alternate%20path%20method" title=" alternate path method"> alternate path method</a> </p> <a href="https://publications.waset.org/abstracts/66231/collapse-analysis-of-planar-composite-frame-under-impact-loads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66231.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">518</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">87</span> Model Evaluation of Thermal Effects Created by Cell Membrane Electroporation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiahui%20Song">Jiahui Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of very high electric fields (~ 100kV/cm or higher) with pulse durations in the nanosecond range has been a recent development. The electric pulses have been used as tools to generate electroporation which has many biomedical applications. Most of the studies of electroporation have ignored possible thermal effects because of the small duration of the applied voltage pulses. However, it has been predicted membrane temperature gradients ranging from 0.2×109 to 109 K/m. This research focuses on thermal gradients that drives for electroporative enhancements, even though the actual temperature values might not have changed appreciably from their equilibrium levels. The dynamics of pore formation with the application of an externally applied electric field is studied on the basis of molecular dynamics (MD) simulations using the GROMACS package. Different temperatures are assigned to various regions to simulate the appropriate temperature gradients. The GROMACS provides the force fields for the lipid membranes, which is taken to comprise of dipalmitoyl-phosphatidyl-choline (DPPC) molecules. The water model mimicks the aqueous environment surrounding the membrane. Velocities of water and membrane molecules are generated randomly at each simulation run according to a Maxwellian distribution. For statistical significance, a total of eight MD simulations are carried out with different starting molecular velocities for each simulation. MD simulation shows no pore is formed in a 10-ns snapshot for a DPPC membrane set at a uniform temperature of 295 K after a 0.4 V/nm electric field is applied. A nano-sized pore is clearly seen in a 10-ns snapshot on the same geometry but with the top and bottom membrane surfaces kept at temperatures of 300 and 295 K, respectively. For the same applied electric field, the formation of nanopores is clearly demonstrated, but only in the presence of a temperature gradient. MD simulation results show enhanced electroporative effects arising from thermal gradients. The study suggests the temperature gradient is a secondary driver, with the electric field being the primary cause for electroporation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanosecond" title="nanosecond">nanosecond</a>, <a href="https://publications.waset.org/abstracts/search?q=electroporation" title=" electroporation"> electroporation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20effects" title=" thermal effects"> thermal effects</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a> </p> <a href="https://publications.waset.org/abstracts/165041/model-evaluation-of-thermal-effects-created-by-cell-membrane-electroporation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165041.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">86</span> Analysing the Interactive Effects of Factors Influencing Sand Production on Drawdown Time in High Viscosity Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerald%20Gwamba">Gerald Gwamba</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20Zhou"> Bo Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yajun%20Song"> Yajun Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Changyin"> Dong Changyin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The challenges that sand production presents to the oil and gas industry, particularly while working in poorly consolidated reservoirs, cannot be overstated. From restricting production to blocking production tubing, sand production increases the costs associated with production as it elevates the cost of servicing production equipment over time. Production in reservoirs that present with high viscosities, flow rate, cementation, clay content as well as fine sand contents is even more complex and challenging. As opposed to the one-factor at a-time testing, investigating the interactive effects arising from a combination of several factors offers increased reliability of results as well as representation of actual field conditions. It is thus paramount to investigate the conditions leading to the onset of sanding during production to ensure the future sustainability of hydrocarbon production operations under viscous conditions. We adopt the Design of Experiments (DOE) to analyse, using Taguchi factorial designs, the most significant interactive effects of sanding. We propose an optimized regression model to predict the drawdown time at sand production. The results obtained underscore that reservoirs characterized by varying (high and low) levels of viscosity, flow rate, cementation, clay, and fine sand content have a resulting impact on sand production. The only significant interactive effect recorded arises from the interaction between BD (fine sand content and flow rate), while the main effects included fluid viscosity and cementation, with percentage significances recorded as 31.3%, 37.76%, and 30.94%, respectively. The drawdown time model presented could be useful for predicting the time to reach the maximum drawdown pressure under viscous conditions during the onset of sand production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=factorial%20designs" title="factorial designs">factorial designs</a>, <a href="https://publications.waset.org/abstracts/search?q=DOE%20optimization" title=" DOE optimization"> DOE optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=sand%20production%20prediction" title=" sand production prediction"> sand production prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=drawdown%20time" title=" drawdown time"> drawdown time</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20model" title=" regression model"> regression model</a> </p> <a href="https://publications.waset.org/abstracts/156494/analysing-the-interactive-effects-of-factors-influencing-sand-production-on-drawdown-time-in-high-viscosity-reservoirs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156494.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">85</span> Investigation of Failure Mechanisms of Composite Laminates with Delamination and Repaired with Bolts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shuxin%20Li">Shuxin Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Peihao%20Song"> Peihao Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Haixiao%20Hu"> Haixiao Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongfeng%20Cao"> Dongfeng Cao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interactive deformation and failure mechanisms, including local bucking/delamination propagation and global bucking, are investigated in this paper with numerical simulation and validation with experimental results. Three dimensional numerical models using ABAQUS brick elements combined with cohesive elements and contact elements are developed to simulate the deformation and failure characteristics of composite laminates with and without delamination under compressive loading. The zero-thickness cohesive elements are inserted on the possible path of delamination propagation, and the inter-laminate behavior is characterized by the mixed-mode traction-separation law. The numerical simulations identified the complex feature of interaction among local buckling and/or delamination propagation and final global bucking for composite laminates with delamination under compressive loading. Firstly there is an interaction between the local buckling and delamination propagation, i.e., local buckling induces delamination propagation, and then delamination growth further enhances the local buckling. Secondly, the interaction between the out-plan deformation caused by local buckling and the global bucking deformation results in final failure of the composite laminates. The simulation results are validated by the good agreement with the experimental results published in the literature. The numerical simulation validated with experimental results revealed that the degradation of the load capacity, in particular of the compressive strength of composite structures with delamination, is mainly attributed to the combined local buckling/delamination propagation effects. Consequently, a simple field-bolt repair approach that can hinder the local buckling and prevent delamination growth is explored. The analysis and simulation results demonstrated field-bolt repair could effectively restore compressive strength of composite laminates with delamination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cohesive%20elements" title="cohesive elements">cohesive elements</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20laminates" title=" composite laminates"> composite laminates</a>, <a href="https://publications.waset.org/abstracts/search?q=delamination" title=" delamination"> delamination</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20and%20global%20bucking" title=" local and global bucking"> local and global bucking</a>, <a href="https://publications.waset.org/abstracts/search?q=field-bolt%20repair" title=" field-bolt repair"> field-bolt repair</a> </p> <a href="https://publications.waset.org/abstracts/118657/investigation-of-failure-mechanisms-of-composite-laminates-with-delamination-and-repaired-with-bolts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118657.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> Rest API Based System-level Test Automation for Mobile Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jisoo%20Song">Jisoo Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today’s mobile applications are communicating with servers more and more in order to access external services or information. Also, server-side code changes are more frequent than client-side code changes in a mobile application. The frequent changes lead to an increase in testing cost increase. To reduce costs, UI based test automation can be one of the solutions. It is a common automation technique in system-level testing. However, it can be unsuitable for mobile applications. When you automate tests based on UI elements for mobile applications, there are some limitations such as the overhead of script maintenance or the difficulty of finding invisible defects that UI elements cannot represent. To overcome these limitations, we present a new automation technique based on Rest API. You can automate system-level tests through test scripts that you write. These scripts call a series of Rest API in a user’s action sequence. This technique does not require testers to know the internal implementation details, only input and expected output of Rest API. You can easily modify test cases by modifying Rest API input values and also find problems that might not be evident from the UI level by validating output values. For example, when an application receives price information from a payment server and user cannot see it at UI level, Rest API based scripts can check whether price information is correct or not. More than 10 mobile applications at our company are being tested automatically based on Rest API scripts whenever application source code, mostly server source code, is built.

This study conducted at in a state university in the Philippines aimed to determine the quality of school life and linguistic intelligence of 214 randomly selected college freshmen. Frequency counts and percentages were used to analyze quality of school life and linguistic intelligence. The chi-square test was utilized to determine significant relationship between quality of school life and linguistic intelligence and selected demographic variables. Results on quality of school life revealed that availability of religious books and paperbacks at home were significantly related to relationship with teachers. None of the selected demographic characteristics were significantly related to sense of achievement. Parents’ highest educational attainment was significantly related with opportunity at school. The availability of general references and song hits were significantly and highly significantly related to sense of identity which means that these promoted their sense of identity since their peers also preferred its availability. Type of high school graduated from was significantly related with students’ self-esteem. Graduates of public high schools have higher boosted self-esteem than those from private high schools. Both type of high school graduated from and reading materials available at home (religious books) had a highly significant relationship with linguistic intelligence. In addition, there was a significant relationship between time spent in reading per day and linguistic intelligence. There was a highly significant relationship between quality of school life in terms of relationship with teachers and sense of achievement with linguistic intelligence. Further, sense of identity and linguistic intelligence were significantly related. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20of%20school%20life" title="quality of school life">quality of school life</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20intelligence" title=" linguistic intelligence"> linguistic intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20freshmen" title=" college freshmen"> college freshmen</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20university" title=" state university"> state university</a> </p> <a href="https://publications.waset.org/abstracts/41292/quality-of-school-life-and-linguistic-intelligence-of-college-freshmen-in-a-state-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41292.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">82</span> Carnatic Music Ragas and Their Role in Music Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raghavi%20Janaswamy">Raghavi Janaswamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Saraswathi%20K.%20Vasudev"> Saraswathi K.

One of the essential components of the music system is the <em>‘tala’ </em>that defines the rhythm of a song. There are seven basic swaras (notes) Sa, Ri, Ga, Ma, Pa, Da and Ni in the carnatic music system that are analogous to the C, D, E, F, G, A and B of the western system. The carnatic music further builds on conscious use of microtones, gamakams (oscillation) and rendering styles. It has basic 72 ragas known as melakarta ragas, and a plethora of ragas have been developed from them with permutations and combinations of the basic swaras. Among them, some ragas derived from a same melakarta raga are distinctly different from each other and could evoke a profound difference in the raga bhava (emotion) during rendering. Although these could bear similar arohana and avarohana swaras, their quintessential differences in the gamakas usage and srutis present therein offer varied melodic feelings; variations in the intonation and stress given to certain swara phrases are the root causes. This article enlightens a group of such allied ragas (AR) from the perspectives of their schema and raga alapana (improvisation), ranjaka prayogas (signature phrases), differences in rendering tempo, gamakas and delicate srutis along with the range of sancharas (musical phrases). The intricate differences on the sruti frequencies and use of AR in composing kritis (musical compositions) toward emotive accomplishments such as mood of valor, kindness, love, humor, anger, mercy to name few, have also been explored. A brief review on the existing scientific research on the music therapy on some of the Carnatic ragas is presented. Studying and comprehending the AR, indeed, enable the music aspirants to gain a thorough knowledge on the subtle nuances among the ragas. Such knowledge helps leave a long-lasting melodic impression on the listeners and enable further research on the music therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carnatic%20music" title="Carnatic music">Carnatic music</a>, <a href="https://publications.waset.org/abstracts/search?q=allied%20ragas" title=" allied ragas"> allied ragas</a>, <a href="https://publications.waset.org/abstracts/search?q=melakarta" title=" melakarta"> melakarta</a>, <a href="https://publications.waset.org/abstracts/search?q=gamakam" title=" gamakam"> gamakam</a> </p> <a href="https://publications.waset.org/abstracts/133062/carnatic-music-ragas-and-their-role-in-music-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133062.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">81</span> Evaluation of the Improve Vacuum Blood Collection Tube for Laboratory Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yoon%20Kyung%20Song">Yoon Kyung Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Won%20Han"> Seung Won Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Hyun%20Hwang"> Sang Hyun Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Do%20Hoon%20Lee"> Do Hoon Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laboratory tests is a significant part for the diagnosis, prognosis, treatment of diseases. Blood collection is a simple process, but can be a potential cause of pre-analytical errors. Vacuum blood collection tubes used to collect and store the blood specimens is necessary for accurate test results. The purpose of this study was to validate Improve serum separator tube(SST) (Guanzhou Improve Medical Instruments Co., Ltd, China) for routine clinical chemistry laboratory testing. Blood specimens were collected from 100 volunteers in three different serum vacuum tubes (Greiner SST , Becton Dickinson SST , Improve SST). The specimens were evaluated for 16 routine chemistry tests using TBA-200FR NEO (Toshiba Medical Co. JAPAN). The results were statistically analyzed by paired t-test and Bland-Altman plot. For stability test, the initial results for each tube were compared with results of 72 hours preserved specimens. Their clinical availability was evaluated by biological Variation of Ricos data bank. Paired t-test analysis revealed that AST, ALT, K, Cl showed statistically same results but calcium (CA), phosphorus(PHOS), glucose(GLU), BUN, uric acid(UA), cholesterol(CHOL), total protein(TP), albumin(ALB), total bilirubin(TB), ALP, creatinine(CRE), sodium(NA) were different(P < 0.05) between Improve SST and Greiner SST. Also, CA, PHOS, TP, TB, AST, ALT, NA, K, Cl showed statistically the same results but GLU, BUN, UA, CHOL, ALB, ALP, CRE were different between Improve SST and Becton Dickinson SST. All statistically different cases were clinically acceptable by biological Variation of Ricos data bank. Improve SST tubes showed satisfactory results compared with Greiner SST and Becton Dickinson SST. We concluded that the tubes are acceptable for routine clinical chemistry laboratory testing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blood%20collection" title="blood collection">blood collection</a>, <a href="https://publications.waset.org/abstracts/search?q=Guanzhou%20Improve" title=" Guanzhou Improve"> Guanzhou Improve</a>, <a href="https://publications.waset.org/abstracts/search?q=SST" title=" SST"> SST</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20tube" title=" vacuum tube"> vacuum tube</a> </p> <a href="https://publications.waset.org/abstracts/44753/evaluation-of-the-improve-vacuum-blood-collection-tube-for-laboratory-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44753.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Physicochemical Characterization of Asphalt Ridge Froth Bitumen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nader%20Nciri">Nader Nciri</a>, <a href="https://publications.waset.org/abstracts/search?q=Suil%20Song"> Suil Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Namho%20Kim"> Namho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Namjun%20Cho"> Namjun Cho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Properties and compositions of bitumen and bitumen-derived liquids have significant influences on the selection of recovery, upgrading and refining processes. Optimal process conditions can often be directly related to these properties. The end uses of bitumen and bitumen products are thus related to their compositions. Because it is not possible to conduct a complete analysis of the molecular structure of bitumen, characterization must be made in other terms. The present paper focuses on physico-chemical analysis of two different types of bitumens. These bitumen samples were chosen based on: the original crude oil (sand oil and crude petroleum), and mode of process. The aim of this study is to determine both the manufacturing effect on chemical species and the chemical organization as a function of the type of bitumen sample. In order to obtain information on bitumen chemistry, elemental analysis (C, H, N, S, and O), heavy metal (Ni, V) concentrations, IATROSCAN chromatography (thin layer chromatography-flame ionization detection), FTIR spectroscopy, and 1H NMR spectroscopy have all been used. The characterization includes information about the major compound types (saturates, aromatics, resins and asphaltenes) which can be compared with similar data for other bitumens, more importantly, can be correlated with data from petroleum samples for which refining characteristics are known. Examination of Asphalt Ridge froth bitumen showed that it differed significantly from representative petroleum pitches, principally in their nonhydrocarbon content, heavy metal content and aromatic compounds. When possible, properties and composition were related to recovery and refining processes. This information is important because of the effects that composition has on recovery and processing reactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=froth%20bitumen" title="froth bitumen">froth bitumen</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20sand" title=" oil sand"> oil sand</a>, <a href="https://publications.waset.org/abstracts/search?q=asphalt%20ridge" title=" asphalt ridge"> asphalt ridge</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum%20pitch" title=" petroleum pitch"> petroleum pitch</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20layer%20chromatography-flame%20ionization%20detection" title=" thin layer chromatography-flame ionization detection"> thin layer chromatography-flame ionization detection</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20spectroscopy" title=" infrared spectroscopy"> infrared spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=1H%20nuclear%20magnetic%20resonance%20spectroscopy" title=" 1H nuclear magnetic resonance spectroscopy"> 1H nuclear magnetic resonance spectroscopy</a> </p> <a href="https://publications.waset.org/abstracts/1883/physicochemical-characterization-of-asphalt-ridge-froth-bitumen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1883.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">427</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">79</span> E-learning resources for radiology training: Is an ideal program available?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eric%20Fang">Eric Fang</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Chen"> Robert Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghim%20Song%20Chia"> Ghim Song Chia</a>, <a href="https://publications.waset.org/abstracts/search?q=Bien%20Soo%20Tan"> Bien Soo Tan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective and Rationale: Training of radiology residents hinges on practical, on-the-job training in all facets and modalities of diagnostic radiology. Although residency is structured to be comprehensive, clinical exposure depends on the case mix available locally and during the posting period. To supplement clinical training, there are several e-learning resources available to allow for greater exposure to radiological cases. The objective of this study was to survey residents and faculty on the usefulness of these e-learning resources. Methods: E-learning resources were shortlisted with input from radiology residents, Google search and online discussion groups, and screened by their purported focus. Twelve e-learning resources were found to meet the criteria. Both radiology residents and experienced radiology faculty were then surveyed electronically. The e-survey asked for ratings on breadth, depth, testing capability and user-friendliness for each resource, as well as for rankings for the top 3 resources. Statistical analysis was performed using SAS 9.4. Results: Seventeen residents and fifteen faculties completed an e-survey. Mean response rate was 54% ± 8% (Range: 14- 96%). Ratings and rankings were statistically identical between residents and faculty. On a 5-point rating scale, breadth was 3.68 ± 0.18, depth was 3.95 ± 0.14, testing capability was 2.64 ± 0.16 and user-friendliness was 3.39 ± 0.13. Top-ranked resources were STATdx (first), Radiopaedia (second) and Radiology Assistant (third). 9% of responders singled out R-ITI as potentially good but ‘prohibitively costly’. Statistically significant predictive factors for higher rankings are familiarity with the resource (p = 0.001) and user-friendliness (p = 0.006). Conclusion: A good e-learning system will complement on-the-job training with a broad case base, deep discussion and quality trainee evaluation. Based on our study on twelve e-learning resources, no single program fulfilled all requirements. The perception and use of radiology e-learning resources depended more on familiarity and user-friendliness than on content differences and testing capability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=e-learning" title="e-learning">e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=medicine" title=" medicine"> medicine</a>, <a href="https://publications.waset.org/abstracts/search?q=radiology" title=" radiology"> radiology</a>, <a href="https://publications.waset.org/abstracts/search?q=survey" title=" survey"> survey</a> </p> <a href="https://publications.waset.org/abstracts/38172/e-learning-resources-for-radiology-training-is-an-ideal-program-available" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38172.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">78</span> Improved Benzene Selctivity for Methane Dehydroaromatization via Modifying the Zeolitic Pores by Dual Templating Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deepti%20Mishra">Deepti Mishra</a>, <a href="https://publications.waset.org/abstracts/search?q=K.%20K%20Pant"> K.

Under such conditions, it necessitates the design of micro/mesoporous ZSM-5, which has the advantages viz. uniform dispersibility of MoOx species, consequently the formation of active Mo sites in the micro/mesoporous channel and lower carbon deposition because of improved mass transfer rate within the hierarchical pores. In this study, we report a unique strategy to control the porous structures of ZSM-5 through a dual templating approach, utilizing C6 and C12 -surfactants as porogen. DFT studies were carried out to correlate the ZSM-5 framework development using the C6 and C12 surfactants with structure directing agent. The structural and morphological parameters of the synthesized ZSM-5 were explored in detail to determine the crystallinity, porosity, Si/Al ratio, particle shape, size, and acidic strength, which were further correlated with the physicochemical and catalytic properties of Mo modified HZSM-5 catalysts. After Mo incorporation, all the catalysts were tested for MDA reaction. From the activity test, it was observed that C6 surfactant-modified hierarchically porous Mo/HZSM-5(H) showed the highest benzene formation rate (1.5 μmol/gcat. s) and longer catalytic stability up to 270 min of reaction as compared to the conventional microporous Mo/HZSM-5(C). In contrary, C12 surfactant modified Mo/HZSM-5(D) is inferior towards MDA reaction (benzene formation rate: 0.5 μmol/gcat. s). We ascribed that the difference in MDA activity could be due to the hierarchically interconnected meso/microporous feature of Mo/HZSM-5(H) that precludes secondary reaction of coking from benzene and hence contributing substantial stability towards MDA reaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20pores" title="hierarchical pores">hierarchical pores</a>, <a href="https://publications.waset.org/abstracts/search?q=Mo%2FHZSM-5" title=" Mo/HZSM-5"> Mo/HZSM-5</a>, <a href="https://publications.waset.org/abstracts/search?q=methane%20dehydroaromatization" title=" methane dehydroaromatization"> methane dehydroaromatization</a>, <a href="https://publications.waset.org/abstracts/search?q=coke%20deposition" title=" coke deposition"> coke deposition</a> </p> <a href="https://publications.waset.org/abstracts/159920/improved-benzene-selctivity-for-methane-dehydroaromatization-via-modifying-the-zeolitic-pores-by-dual-templating-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159920.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">82</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">77</span> Urinary Exosome miR-30c-5p as a Biomarker for Early-Stage Clear Cell Renal Cell Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shangqing%20Song">Shangqing Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Xu"> Bin Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yajun%20Cheng"> Yajun Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhong%20Wang"> Zhong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> miRNAs derived from exosomes exist in a body fluid such as urine were regarded as potential biomarkers for various human cancers diagnosis and prognosis, as mature miRNAs can be steadily preserved by exosomes. However, its potential value in clear cell renal cell carcinoma (ccRCC) diagnosis and prognosis remains unclear. In the present study, differentially expressed miRNAs from urinal exosomes were identified by next-generation sequencing (NGS) technology. The 16 differentially expressed miRNAs were identified between ccRCC patients and healthy donors. To explore the specific diagnosis biomarker of ccRCC, we validated these urinary exosomes from 70 early-stage renal cancer patients, 30 healthy people and other urinary system cancers, including 30 early-stage prostate cancer patients and 30 early-stage bladder cancer patients by qRT-PCR. The results showed that urinary exosome miR-30c-5p could be stably amplified and meanwhile the expression of miR-30c-5p has no significant difference between other urinary system cancers and healthy control, however, expression level of miR-30c-5p in urinary exosomal of ccRCC patients was lower than healthy people and receiver operation characterization (ROC) curve showed that the area under the curve (AUC) values was 0.8192 (95% confidence interval was 0.7388-0.8996, P= 0.0000). In addition, up-regulating miR-30c-5p expression could inhibit renal cell carcinoma cells growth. Lastly, HSP5A was found as a direct target gene of miR-30c-5p. HSP5A depletion reversed the promoting effect of ccRCC growth casued by miR-30c-5p inhibitor, respectively. In conclusion, this study demonstrated that urinary exosomal miR-30c-5p is readily accessible as diagnosis biomarker of early-stage ccRCC, and miR-30c-5p might modulate the expression of HSPA5, which correlated with the progression of ccRCC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clear%20cell%20renal%20cell%20carcinoma" title="clear cell renal cell carcinoma">clear cell renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=exosome" title=" exosome"> exosome</a>, <a href="https://publications.waset.org/abstracts/search?q=HSP5A" title=" HSP5A"> HSP5A</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-30c-5p" title=" miR-30c-5p"> miR-30c-5p</a> </p> <a href="https://publications.waset.org/abstracts/93777/urinary-exosome-mir-30c-5p-as-a-biomarker-for-early-stage-clear-cell-renal-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93777.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">76</span> Photocapacitor Integrating Solar Energy Conversion and Energy Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jihuai%20Wu">Jihuai Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zeyu%20Song"> Zeyu Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Lan"> Zhang Lan</a>, <a href="https://publications.waset.org/abstracts/search?q=Liuxue%20Sun"> Liuxue Sun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solar energy is clean, open, and infinite, but solar radiation on the earth is fluctuating, intermittent, and unstable. So, the sustainable utilization of solar energy requires a combination of high-efficient energy conversion and low-loss energy storage technologies. Hence, a photo capacitor integrated with photo-electrical conversion and electric-chemical storage functions in single device is a cost-effective, volume-effective and functional-effective optimal choice. However, owing to the multiple components, multi-dimensional structure and multiple functions in one device, especially the mismatch of the functional modules, the overall conversion and storage efficiency of the photocapacitors is less than 13%, which seriously limits the development of the integrated system of solar conversion and energy storage. To this end, two typical photocapacitors were studied. A three-terminal photocapacitor was integrated by using perovskite solar cell as solar conversion module and symmetrical supercapacitor as energy storage module. A function portfolio management concept was proposed the relationship among various efficiencies during photovoltaic conversion and energy storage process were clarified. By harmonizing the energy matching between conversion and storage modules and seeking the maximum power points coincide and the maximum efficiency points synchronize, the overall efficiency of the photocapacitor surpassed 18 %, and Joule efficiency was closed to 90%. A voltage adjustable hybrid supercapacitor (VAHSC) was designed as energy storage module, and two Si wafers in series as solar conversion module, a three-terminal photocapacitor was fabricated. The VAHSC effectively harmonizes the energy harvest and storage modules, resulting in the current, voltage, power, and energy match between both modules. The optimal photocapacitor achieved an overall efficiency of 15.49% and Joule efficiency of 86.01%, along with excellent charge/discharge cycle stability. In addition, the Joule efficiency (ηJoule) was defined as the energy ratio of discharge/charge of the devices for the first time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joule%20efficiency" title="joule efficiency">joule efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=perovskite%20solar%20cell" title=" perovskite solar cell"> perovskite solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=photocapacitor" title=" photocapacitor"> photocapacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20solar%20cell" title=" silicon solar cell"> silicon solar cell</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitor" title=" supercapacitor"> supercapacitor</a> </p> <a href="https://publications.waset.org/abstracts/168790/photocapacitor-integrating-solar-energy-conversion-and-energy-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">75</span> Prenatal Exposure to Organophosphate Pesticide and Fetal Growth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yi-Shuan%20ShaoShao">Yi-Shuan ShaoShao</a>, <a href="https://publications.waset.org/abstracts/search?q=Yen-An%20Tsai"> Yen-An Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chia-Huang%20Chang"> Chia-Huang Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kai-Wei%20Liao"> Kai-Wei Liao</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Song%20Tsai"> Ming-Song Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Mei-Lien%20Chen"> Mei-Lien Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organophosphate pesticides (OPs) is an environmental hormone with proven endocrine-disrupting effects that may affect the growth and development in human. A large amount of organophosphate pesticides (OPs) is used throughout Taiwan, and human may be exposed through dietary intake or residential use. During pregnancy, OPs can be transferred to the blood stream reaching the fetus through the placenta. The aim of this study was to explore the association between maternal OPs exposure levels and fetal developments and birth outcomes. A birth cohort was follow-up. Maternal urine sample were collected at the first, second, and third gestational trimester. Fetal growth characteristics were measured by ultrasonic scan and birth outcomes were assessed by pediatrician. Urinary metabolite of organophosphate pesticides were assessed using gas chromatography-mass spectrometry. The analytes included dimethylphosphate (DMP), dimethylthiophosphate (DMTP), dimethyldithiophosphates (DMDTP), diethylphosphate (DEP), diethylthiophosphate (DETP), and diethyldithiophosphate (DEDTP). We found that all of urine samples in each trimester were detected at least one metabolite for dialkyl phosphate (DAP). The detection rate range of OP urinary metabolites were from the lowest 22% DEDTP to the highest 100% DMP and DMTP. And to compared geometric means (GM) of urinary metabolites with three trimesters, that third trimester had the highest concentration for DMPs, DEPs, and DAPs in pregnant women were 368.01, 169.85 and 543.75 nmol/g creatinine, respectively. We observed that DAPs concentration in first and second trimester were significantly negative association with head circumference. DMPs in first trimester was significantly negative association with thoracic circumference (p=0.05) by spearman correlation. Our results support associations with prenatal OPs exposure with fetal head circumference and thoracic circumference. It provided that maternal OPs exposure might affect birth outcomes. Thus, prenatal exposure to OPs and health risk worthy of attention and concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DAPs" title="DAPs">DAPs</a>, <a href="https://publications.waset.org/abstracts/search?q=birth%20outcomes" title=" birth outcomes"> birth outcomes</a>, <a href="https://publications.waset.org/abstracts/search?q=organophosphate%20pesticides" title=" organophosphate pesticides"> organophosphate pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=prenatal" title=" prenatal"> prenatal</a> </p> <a href="https://publications.waset.org/abstracts/42358/prenatal-exposure-to-organophosphate-pesticide-and-fetal-growth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42358.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">74</span> Portuguese Guitar Strings Characterization and Comparison</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Serr%C3%A3o">P.

The Portuguese guitar is a pear-shaped plucked chordophone with six courses of double strings. This study compares the two types of plain strings available for Portuguese guitar and used by the musicians. One is stainless steel spring wire, the other is high carbon spring steel (music wire). Some musicians mention noticeable differences in sound quality between these two string materials, such as a little more brightness and sustain in the steel strings. Experimental tests were performed to characterize string tension at pitch; mechanical strength and tuning stability using the universal testing machine; dimensional control and chemical composition analysis using the scanning electron microscope. The string dynamical behaviour characterization experiments, including frequency response, inharmonicity, transient response, damping phenomena and were made in a monochord test set-up designed and built in-house. Damping factor was determined for the fundamental frequency. As musicians are able to detect very small damping differences, an accurate a characterization of the damping phenomena for all harmonics was necessary. With that purpose, another improved monochord was set and a new system identification methodology applied. Due to the complexity of this task several adjustments were necessary until obtaining good experimental data. In a few cases, dynamical tests were repeated to detect any evolution in damping parameters after break-in period when according to players experience a new string sounds gradually less dull until reaching the typically brilliant timbre. Finally, each set of strings was played on one guitar by a distinguished player and recorded. The recordings which include individual notes, scales, chords and a study piece, will be analysed to potentially characterize timbre variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damping%20factor" title="damping factor">damping factor</a>, <a href="https://publications.waset.org/abstracts/search?q=music%20wire" title=" music wire"> music wire</a>, <a href="https://publications.waset.org/abstracts/search?q=portuguese%20guitar" title=" portuguese guitar"> portuguese guitar</a>, <a href="https://publications.waset.org/abstracts/search?q=string%20dynamics" title=" string dynamics"> string dynamics</a> </p> <a href="https://publications.waset.org/abstracts/35885/portuguese-guitar-strings-characterization-and-comparison" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35885.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">553</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">73</span> Molecular Dynamics Simulation Studies of Thermal Effects Created by High-Intensity, Ultra-Short Pulses Induced Cell Membrane Electroporation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jiahui%20Song">Jiahui Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of electric fields with high intensity (~ 100kV/cm or higher) and ultra short pulse durations (nanosecond range) has been a recent development. Most of the studies of electroporation have ignored possible thermal effects because of the small duration of the applied voltage pulses. However, it has been predicted membrane temperature gradients ranging from 0.2×109 to 109 K/m. This research focuses on thermal effects that drive for electroporative enhancements, even though the actual temperature values might not have changed appreciably from their equilibrium levels. The dynamics of pore formation with the application of an externally applied electric field is studied on the basis of molecular dynamics (MD) simulations using the GROMACS package. MD simulations of a lipid layer with constant electric field strength of 0.5 V/nm at 25 °C and 47 °C are implemented to simulate the appropriate thermal effects. The GROMACS provides the force fields for the lipid membranes, which is taken to comprise of dipalmitoyl-phosphatidyl-choline (DPPC) molecules. The water model mimicks the aqueous environment surrounding the membrane. Velocities of water and membrane molecules are generated randomly at each simulation run according to a Maxwellian distribution. The high background electric field is typically used in MD simulations to probe electroporation. It serves as an accelerated test of the pore formation process since low electric fields would take inordinately long simulation time. MD simulation shows no pore is formed in a 1-ns snapshot for a DPPC membrane set at a temperature of 25°C after a 0.5 V/nm electric field is applied. A nano-sized pore is clearly seen in a 0.75-ns snapshot on the same geometry, but with the membrane surfaces kept at temperatures of 47°C. And the pore increases at 1 ns. The MD simulation results suggest the possibility that the increase in temperature can result in different degrees of electrically stimulated bio-effects. The results points to the role of thermal effects in facilitating and accelerating the electroporation process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high-intensity" title="high-intensity">high-intensity</a>, <a href="https://publications.waset.org/abstracts/search?q=ultra-short" title=" ultra-short"> ultra-short</a>, <a href="https://publications.waset.org/abstracts/search?q=electroporation" title=" electroporation"> electroporation</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20effects" title=" thermal effects"> thermal effects</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a> </p> <a href="https://publications.waset.org/abstracts/182955/molecular-dynamics-simulation-studies-of-thermal-effects-created-by-high-intensity-ultra-short-pulses-induced-cell-membrane-electroporation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182955.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">52</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">72</span> The Effect of Penalizing Wrong Answers in the Computerized Modified Multiple Choice Testing System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Hae%20Song">Min Hae Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Jooyong%20Park"> Jooyong Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Even though assessment using information and communication technology will most likely lead the future of educational assessment, there is little research on this topic. Computerized assessment will not only cut costs but also measure students' performance in ways not possible before. In this context, this study introduces a tool which can overcome the problems of multiple choice tests. Multiple-choice tests (MC) are efficient in automatic grading, however structural problems of multiple-choice tests allow students to find the correct answer from options even though they do not know the answer. A computerized modified multiple-choice testing system (CMMT) was developed using the interactivity of computers, that presents questions first, and options later for a short time when the student requests for them. This study was conducted to find out whether penalizing for wrong answers in CMMT could lower random guessing. In this study, we checked whether students knew the answers by having them respond to the short-answer tests before choosing the given options in CMMT or MC format. Ninety-four students were tested with the directions that they will be penalized for wrong answers, but not for no response. There were 4 experimental conditions: two conditions of high or low percentage of penalizing, each in traditional multiple-choice or CMMT format. In the low penalty condition, the penalty rate was the probability of getting the correct answer by random guessing. In the high penalty condition, students were penalized at twice the percentage of the low penalty condition. The results showed that the number of no response was significantly higher for the CMMT format and the number of random guesses was significantly lower for the CMMT format. There were no significant between the two penalty conditions. This result may be due to the fact that the actual score difference between the two conditions was too small. In the discussion, the possibility of applying CMMT format tests while penalizing wrong answers in actual testing settings was addressed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computerized%20modified%20multiple%20choice%20test%20format" title="computerized modified multiple choice test format">computerized modified multiple choice test format</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple-choice%20test%20format" title=" multiple-choice test format"> multiple-choice test format</a>, <a href="https://publications.waset.org/abstracts/search?q=penalizing" title=" penalizing"> penalizing</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20format" title=" test format"> test format</a> </p> <a href="https://publications.waset.org/abstracts/92283/the-effect-of-penalizing-wrong-answers-in-the-computerized-modified-multiple-choice-testing-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92283.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">71</span> The Current Level of Shared Decision-Making in Head-And-Neck Oncology: An Exploratory Study – Preliminary Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anne%20N.%20Heirman">Anne N.

Shared decision-making (SDM) beholds a collaboration between patient and doctor in which the most suitable treatment can be chosen by integrating patient preferences, values, and medical information. SDM has a lot of advantages that would be useful in making difficult treatment choices. The objective of this study was to determine the current level of SDM among patients and head-and-neck surgeons. Methods: Consultations of patients with a non-cutaneous head-and-neck malignancy facing a treatment decision were selected and included. If given informed consent, the consultation was recorded with an audio recorder, and the patient and surgeon filled in a questionnaire immediately after the consultation. The SDM level of the consultation was scored objectively by independent observers who judged audio recordings of the consultation using the OPTION5-scale, ranging from 0% (no SDM) to 100% (optimum SDM), as well as subjectively by patients (using the SDM-Q-9 and Control preference scale) and clinicians (SDM-Q-Doc, modified control preference scale) percentages. Preliminary results: Five head-neck surgeons have each at least seven recorded conversations with different patients. One of them was trained in SDM. The other four had no experience with SDM. Most patients were male (74%), and oropharyngeal carcinoma was the most common diagnosis (41%), followed by oral cancer (33%). Five patients received palliative treatment of which two patients were not treated recording guidelines. At this moment, all recordings are scored by the two independent observers. Analysis of the results will follow soon. Conclusion: The current study will determine to what extent there is a discrepancy between the objective and subjective level of shared decision-making (SDM) during a doctor-patient consultation in Head-and-Neck surgery. The results of the analysis will follow shortly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=head-and-neck%20oncology" title="head-and-neck oncology">head-and-neck oncology</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20involvement" title=" patient involvement"> patient involvement</a>, <a href="https://publications.waset.org/abstracts/search?q=physician-patient%20relations" title=" physician-patient relations"> physician-patient relations</a>, <a href="https://publications.waset.org/abstracts/search?q=shared%20decision%20making" title=" shared decision making"> shared decision making</a> </p> <a href="https://publications.waset.org/abstracts/154163/the-current-level-of-shared-decision-making-in-head-and-neck-oncology-an-exploratory-study-preliminary-results" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154163.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">70</span> Disaster Response Training Simulator Based on Augmented Reality, Virtual Reality, and MPEG-DASH</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunho%20Seo">Sunho Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Younghwan%20Shin"> Younghwan Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Hong%20Park"> Jong-Hong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Sooeun%20Song"> Sooeun Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Junsung%20Kim"> Junsung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jusik%20Yun"> Jusik Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongkyun%20Kim"> Yongkyun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Moon%20Chung"> Jong-Moon Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to effectively cope with large and complex disasters, disaster response training is needed. Recently, disaster response training led by the ROK (Republic of Korea) government is being implemented through a 4 year R&D project, which has several similar functions as the HSEEP (Homeland Security Exercise and Evaluation Program) of the United States, but also has several different features as well. Due to the unpredictiveness and diversity of disasters, existing training methods have many limitations in providing experience in the efficient use of disaster incident response and recovery resources. Always, the challenge is to be as efficient and effective as possible using the limited human and material/physical resources available based on the given time and environmental circumstances. To enable repeated training under diverse scenarios, an AR (Augmented Reality) and VR (Virtual Reality) combined simulator is under development. Unlike existing disaster response training, simulator based training (that allows remote login simultaneous multi-user training) enables freedom from limitations in time and space constraints, and can be repeatedly trained with different combinations of functions and disaster situations. There are related systems such as ADMS (Advanced Disaster Management Simulator) developed by ETC simulation and HLS2 (Homeland Security Simulation System) developed by ELBIT system. However, the ROK government needs a simulator custom made to the country's environment and disaster types, and also combines the latest information and communication technologies, which include AR, VR, and MPEG-DASH (Moving Picture Experts Group - Dynamic Adaptive Streaming over HTTP) technology. In this paper, a new disaster response training simulator is proposed to overcome the limitation of existing training systems, and adapted to actual disaster situations in the ROK, where several technical features are described. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=augmented%20reality" title="augmented reality">augmented reality</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20response%20training%20simulator" title=" emergency response training simulator"> emergency response training simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=MPEG-DASH" title=" MPEG-DASH"> MPEG-DASH</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title=" virtual reality"> virtual reality</a> </p> <a href="https://publications.waset.org/abstracts/67510/disaster-response-training-simulator-based-on-augmented-reality-virtual-reality-and-mpeg-dash" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67510.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> A New Direction of Urban Regeneration: Form-Based Urban Reconstruction through the Idea of Bricolage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyejin%20Song">Hyejin Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin%20Baek"> Jin Baek </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on the idea of bricolage that a new meaning beyond that of each of objects can be created through combination and juxtaposition of various objets, this study finds a way of morphological-recomposing of urban space through combination and juxtaposition of existing urban fabric and new fabric and suggests this idea as new direction of urban regeneration. This study sets concept of bricolage as a philosophical ground of interpreting contemporary urban situation. In this concept, urban objects such as buildings from various zeitgeists are positively considered as potential textures which can construct meaningful context. Seoul, as the city having long history and experiencing colonization and development, appears dynamic urban structure full of various objects from various periods. However, in contrast with successful plazas and streets in Europe, objects in Seoul do not make a meaningful context as public space due to thoughtless development. This study defines this situation as ‘disorgnized-fabric’. Following the concept of bricolage, to find the way for those existing scattered objects to be organized as a context of meaningful public space, this study firstly researches the case of successful public space by morphological analysis. Secondly, this study carefully explores urban space in Seoul, and draws figure-ground diagram to grasp the form of current urban fabric by various urban-objects. As a result of exploration, a lot of urban spaces from Myeong-dong, one of vibrant commercial district in Seoul, to declining residential area are judged as having potential fabric which can become meaningful context by just small adjustment of relationship between existing objects. This study also confirmed that by inserting a new object with consideration of form of existing fabric, it is possible to accord a new context as plaza to existing void which have broken as several parts. This study defines it as form-based urban reconstruction through the idea of bricolage, and suggests that it could be one of philosophical ground of successful urban regeneration. <p
