Laurencian acetogenins are entirly C15 non-terpenoid haloethers with different carbocyclic nuclei; a specimen of the Red Sea red alga L. obtusa was investigated for its acetogenin content. The dichloromethane extract of the air-dried red algal material was fractionated on aluminum oxide column preparative thin-layer chromatography. Three new rare C12 acetogenin derivatives (1-3) were isolated from the organic extract obtained from Laurencia obtusa, collected from the territorial Red Sea water of Saudi Arabia. The structures of the isolated metabolites were established by means of spectroscopical data analyses. Examining the isolated compounds in activated human peripheral blood mononuclear cells (PBMC) revealed potent Anti-inflammatory activity as evidenced by inhibition of NFκB and release of other inflammatory mediators like TNF-α, IL-1β and IL-6. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Red%20Sea" title="Red Sea">Red Sea</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20algae" title=" red algae"> red algae</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopy" title=" spectroscopy"> spectroscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory" title=" anti-inflammatory"> anti-inflammatory</a> </p> <a href="https://publications.waset.org/abstracts/85016/bioactive-rare-acetogenins-from-the-red-alga-laurencia-obtusa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85016.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">148</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">44</span> Parameter Study for TPU Nanofibers Fabricated via Centrifugal Spinning </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Akg%C3%BCl">Yasin Akgül</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Polat"> Yusuf Polat</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Canbay"> Emine Canbay</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20K%C4%B1l%C4%B1%C3%A7"> Ali Kılıç</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrospinning is the most common method to produce nanofibers.

Fractionation and purification of the CH₂Cl₂/MeOH extract were done by applying several chromatographic techniques, including column and preparative thin-layer chromatography; followed by a series of ¹H nuclear magnetic resonance measurements to give rise of some interesting notes. A new rare chloroallene-based C₁₅ acetogenin, laurentusenin (1) along with a new furan ring containing C₁₅ acetogenin, laurenfuresenin (2), were isolated from the red alga L. obtusa. Comparing 1D and 2D NMR, MS, UV and IR spectral data for the new isolated compounds with the reported bromoallene containing acetogenins spectral data was played the crucial role for characterization of their hemical structures. The apoptosis induced by these two compounds was demonstrated by DNA fragmentation assay and microscopic observation. These observations suggest that (1) and (2) may be involved in regulation of programmed death in the initiation and propagation of inflammatory responses. The isolated metabolite (1) showed unusual substituted allene side chain, while (2) inserted furan ring as a new acetogenin nucleus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cyclic%20enyne" title="cyclic enyne">cyclic enyne</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-inflammatory" title=" anti-inflammatory"> anti-inflammatory</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20algae" title=" marine algae"> marine algae</a>, <a href="https://publications.waset.org/abstracts/search?q=halogenations" title=" halogenations"> halogenations</a> </p> <a href="https://publications.waset.org/abstracts/84933/isolation-of-new-c15-acetogenins-from-the-red-alga-laurencia-obtusa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84933.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">151</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">42</span> Producing TPU/Propolis Nanofibrous Membrane as Wound Dressing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Akg%C3%BCl">Yasin Akgül</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Polat"> Yusuf Polat</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Canbay"> Emine Canbay</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20K%C4%B1l%C4%B1%C3%A7"> Ali Kılıç </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wound dressings have strategically and economic importance considering increase of chronic wounds in the world.

Digital tachographs are mandatory for vehicles used in people and goods transport and they are an important aspect for road safety and inspection. Digital tachographs need to be calibrated for workshops in order for the digital tachograph to display and record speed and odometer values correctly. Calibration of digital tachographs can be performed either manual or automatic. It is shown in this paper that manual calibration of digital tachographs is prone to errors and there can be differences between manual and automatic calibration parameters. Therefore automatic calibration methods are imperative for digital tachograph calibration. The presented experimental results and error analysis clearly support the claims of the paper by evaluating and statistically comparing manual and automatic calibration methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20tachograph" title="digital tachograph">digital tachograph</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20safety" title=" road safety"> road safety</a>, <a href="https://publications.waset.org/abstracts/search?q=tachograph%20calibration" title=" tachograph calibration"> tachograph calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=tachograph%20workshops" title=" tachograph workshops"> tachograph workshops</a> </p> <a href="https://publications.waset.org/abstracts/82352/evaluation-of-manual-and-automatic-calibration-methods-for-digital-tachographs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82352.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">37</span> Engoglaze Development for the Production of Glazed Porcelain Tiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sezgi%20Isik">Sezgi Isik</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Urersoy"> Yasin Urersoy</a>, <a href="https://publications.waset.org/abstracts/search?q=Gizem%20Ustunel"> Gizem Ustunel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilkyaz%20Yalcin"> Ilkyaz Yalcin </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improvement of the digital tile application, lots of process revolutions have occurred in the tile production. In order to create unique and inimitable designs, all the competitors start to try different applications. Both Europian and domestic ceramic producers focus on the deep and realistic surfaces. In this study, the trend of engoglaze, which is becoming widespread in glaze porcelain tile designs to create the most intensive colours, were investigated. The aim of the study is to develop engoglaze formulation that supports digital ink activation. Thermal expansion coefficient values were determined by a dilatometer. Chemical analyses and sintering behaviors of engoglazes were made by X-ray diffraction and heat microscopy analysis. According to these glaze formulation studies, it has been reported that using engoglaze could easily reduce the digital ink consumption of the design. On the other hand, the advantage of the production cost is gained, and deepness of the design is provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramic" title="ceramic">ceramic</a>, <a href="https://publications.waset.org/abstracts/search?q=engoglaze" title=" engoglaze"> engoglaze</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20ink%20activation" title=" digital ink activation"> digital ink activation</a>, <a href="https://publications.waset.org/abstracts/search?q=glazed%20porcelain%20tile" title=" glazed porcelain tile"> glazed porcelain tile</a> </p> <a href="https://publications.waset.org/abstracts/110138/engoglaze-development-for-the-production-of-glazed-porcelain-tiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110138.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">132</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">36</span> Predictors, Barriers, and Facilitators to Refugee Women’s Employment and Economic Inclusion: A Mixed Methods Systematic Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Areej%20Al-Hamad">Areej Al-Hamad</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Yasin"> Yasin Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kateryna%20Metersky"> Kateryna Metersky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This mixed-method systematic review and meta-analysis provide an encompassing understanding of the barriers, facilitators, and predictors of refugee women's employment and economic inclusion. The study sheds light on the complex interplay of sociocultural, personal, political, and environmental factors influencing these outcomes, underlining the urgent need for a multifaceted, tailored approach to devising strategies, policies, and interventions aimed at boosting refugee women's economic empowerment. Our findings suggest that sociocultural factors, including gender norms, societal attitudes, language proficiency, and social networks, profoundly shape refugee women's access to and participation in the labor market. Personal factors such as age, educational attainment, health status, skills, and previous work experience also play significant roles. Political factors like immigration policies, regulations, and rights to work, alongside environmental factors like labor market conditions, availability of employment opportunities, and access to resources and support services, further contribute to the complex dynamics influencing refugee women's economic inclusion. The significant variability observed in the impacts of these factors across different contexts underscores the necessity of adopting population and region-specific strategies. A one-size-fits-all approach may prove to be ineffective due to the diversity and unique circumstances of refugee women across different geographical, cultural, and political contexts. The study's findings have profound implications for policy-making, practice, education, and research. The insights garnered a call for coordinated efforts across these domains to bolster refugee women's economic participation. In policy-making, the findings necessitate a reassessment of current immigration and labor market policies to ensure they adequately support refugee women's employment and economic integration. In practice, they highlight the need for comprehensive, tailored employment services and interventions that address the specific barriers and leverage the facilitators identified. In education, they underline the importance of language and skills training programs that cater to the unique needs and circumstances of refugee women. Lastly, in research, they emphasize the need for ongoing investigations into the multifaceted factors influencing refugee women's employment experiences, allowing for continuous refinement of our understanding and interventions. Through this comprehensive exploration, the study contributes to ongoing efforts aimed at creating more inclusive, equitable societies. By continually refining our understanding of the complex factors influencing refugee women's employment experiences, we can pave the way toward enhanced economic empowerment for this vulnerable population. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=refugee%20women" title="refugee women">refugee women</a>, <a href="https://publications.waset.org/abstracts/search?q=employment%20barriers" title=" employment barriers"> employment barriers</a>, <a href="https://publications.waset.org/abstracts/search?q=systematic%20review" title=" systematic review"> systematic review</a>, <a href="https://publications.waset.org/abstracts/search?q=employment%20facilitators" title=" employment facilitators"> employment facilitators</a> </p> <a href="https://publications.waset.org/abstracts/169545/predictors-barriers-and-facilitators-to-refugee-womens-employment-and-economic-inclusion-a-mixed-methods-systematic-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169545.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">79</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">35</span> On-Line Consumer Comments (E-Wom): A Case Qualitative Analysis on Resort Hotel Consumers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Bilim">Yasin Bilim</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaaddin%20Ba%C5%9Foda"> Alaaddin Başoda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The recent growth of internet applications on hospitality and tourism provokes on-line consumer comments and reviews.

Despite already guaranteed its existence; in practice such indigenous law is often considered contrary to positive law by legal experts. It is because of legal positivism paradigm which requires the written law as the main reference for the settlement of legal disputes. Carok’s culture is one of the indigenous cultures of Madura to resolve legal disputes that still thrives until today. Carok’s culture is in outside the legal process, and through a fight between the disputing parties until one dies. On the other hand, the legal positivism does not give place to accommodate Carok as indigenous dispute settlement, until it must be solved through trial. This way of settlement has not been successfully satisfying the indigenous people, thus although it has been done through its verdict in the trial, but Carok still be used by them. From the explanation above, Carok’s culture must be accommodated as the main settlement process and legal process of law as the alternative to the effectiveness of dispute resolution in Madura Indonesia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carok" title="carok">carok</a>, <a href="https://publications.waset.org/abstracts/search?q=dispute%20settlement" title=" dispute settlement"> dispute settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20positivism" title=" legal positivism"> legal positivism</a>, <a href="https://publications.waset.org/abstracts/search?q=madura%E2%80%99s%20culture" title=" madura’s culture"> madura’s culture</a> </p> <a href="https://publications.waset.org/abstracts/56553/positivism-legal-controversy-dilemma-carok-as-maduras-culture-through-indigenous-dispute-settlement-in-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56553.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">344</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">33</span> Eco-Ways to Reduce Environmental Impacts of Flame Retardant Textiles at the End of Life</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sohail%20Yasin">Sohail Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Massimo%20Curti"> Massimo Curti</a>, <a href="https://publications.waset.org/abstracts/search?q=Nemeshwaree%20Behary"> Nemeshwaree Behary</a>, <a href="https://publications.waset.org/abstracts/search?q=Giorgio%20Rovero"> Giorgio Rovero</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well-known that the presence of discarded textile products in municipal landfills poses environmental problems due to leaching of chemical products from the textile to the environment. Incineration of such textiles is considered to be an efficient way to produce energy and reduce environmental impacts of textile materials at their end-of life stage. However, the presence of flame retardant products on textiles would decrease the energy yield and emit toxic gases during incineration stage. While some non-durable flame retardants can be removed by wet treatments (e.g. washing), these substances pollute water and pose concerns towards environmental health. Our study shows that infrared radiation can be used efficiently to degrade flame retardant products on the textiles. This method is finalized to minimize the decrease in energy yield during the incineration or gasification processes of flame retardant cotton fabrics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=degradation" title="degradation">degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20retardant" title=" flame retardant"> flame retardant</a>, <a href="https://publications.waset.org/abstracts/search?q=infrared%20radiation" title=" infrared radiation"> infrared radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton" title=" cotton"> cotton</a>, <a href="https://publications.waset.org/abstracts/search?q=incineration" title=" incineration"> incineration</a> </p> <a href="https://publications.waset.org/abstracts/47864/eco-ways-to-reduce-environmental-impacts-of-flame-retardant-textiles-at-the-end-of-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47864.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">366</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">32</span> Beneficial Effect of Biotin in Combination with Canagliflozin on High Fat Diet Induced Diabetes in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rayhana%20Begum">Rayhana Begum</a>, <a href="https://publications.waset.org/abstracts/search?q=HongBin%20Wang"> HongBin Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nur%20Alam%20%20Siddiquee"> Nur Alam Siddiquee</a>, <a href="https://publications.waset.org/abstracts/search?q=Md.Yasin%20Ahmed"> Md.Yasin Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biotin treatment has significant effects on blood glucose, and pharmacological doses of biotin improve hyperglycemia.

The grown ZnO thin films were annealed in oxygen environment at 500°C – 800°C, keeping a step of 100°C for one hour. Room temperature Seebeck measurements showed that Seebeck coefficient and power factor increased from 222 to 510 µV/K and 8.8×10^-6 to 2.6×10^-4 Wm^-1K^-2 as annealing temperature increased from 500°C to 800°C respectively. This is the highest value of Seebeck coefficient ever reported for un-doped MBE grown ZnO according to best of our knowledge. This observation was related with the improvement of crystal structure of grown films with annealing temperature. X-ray diffraction (XRD) results demonstrated that full width half maximum (FWHM) of ZnO (002) plane decreased and crystalline size increased as the annealing temperature increased. Photoluminescence study revealed that the intensity of band edge emission increased and defect emission decreased as annealing temperature increased because the density of oxygen vacancy related donor defects decreased with annealing temperature. This argument was further justified by the Hall measurements which showed a decreasing trend of carrier concentration with annealing temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZnO" title="ZnO">ZnO</a>, <a href="https://publications.waset.org/abstracts/search?q=MBE" title=" MBE"> MBE</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelectric%20properties" title=" thermoelectric properties"> thermoelectric properties</a>, <a href="https://publications.waset.org/abstracts/search?q=annealing%20temperature" title=" annealing temperature"> annealing temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=crystal%20structure" title=" crystal structure"> crystal structure</a> </p> <a href="https://publications.waset.org/abstracts/6667/enhancement-in-seebeck-coefficient-of-mbe-grown-un-doped-zno-by-thermal-annealing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6667.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">445</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">29</span> Wage Differentiation Patterns of Households Revisited for Turkey in Same Industry Employment: A Pseudo-Panel Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Kutuk">Yasin Kutuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Bengi%20Yanik%20Ilhan"> Bengi Yanik Ilhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Previous studies investigate the wage differentiations among regions in Turkey between couples who work in the same industry and those who work in different industries by using the models that is appropriate for cross sectional data. However, since there is no available panel data for this investigation in Turkey, pseudo panels using repeated cross-section data sets of the Household Labor Force Surveys 2004-2014 are employed in order to open a new way to examine wage differentiation patterns. For this purpose, household heads are separated into groups with respect to their household composition. These groups’ membership is assumed to be fixed over time such as age groups, education, gender, and NUTS1 (12 regions) Level. The average behavior of them can be tracked overtime same as in the panel data. Estimates using the pseudo panel data would be consistent with the estimates using genuine panel data on individuals if samples are representative of the population which has fixed composition, characteristics. With controlling the socioeconomic factors, wage differentiation of household income is affected by social, cultural and economic changes after global economic crisis emerged in US.

The main cause of these measurements is to prevent large power failures as cables are prone to aging, which usually results in embrittlement, cracking and eventual failure of the insulating and sheathing materials, exposing the conductor and risking a potential short circuit, a likely cause of the electrical fire. Many distribution networks rely heavily on medium voltage (MV) power cables. The presence of joints in these networks is a vital part of serving the consumer demand for electricity continuously. Such measurements become even more important when the extent of dependence increases. Moreover, it is known that the partial discharge in joints and termination are difficult to track and are the most crucial point of failures in large power systems. This paper discusses the diagnostic techniques of four samples of XLPE insulated cable joints, each included with a different type of defect. Experiments were carried out by measuring PD and tanδ at very low frequency applied high voltage. The results show the importance of combining PD and tanδ for effective cable assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20discharge" title="partial discharge">partial discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=tan%20delta" title=" tan delta"> tan delta</a>, <a href="https://publications.waset.org/abstracts/search?q=very%20low%20frequency" title=" very low frequency"> very low frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=XLPE%20cable" title=" XLPE cable"> XLPE cable</a> </p> <a href="https://publications.waset.org/abstracts/147680/the-use-of-pd-and-tand-characteristics-as-diagnostic-technique-for-the-insulation-integrity-of-xlpe-insulated-cable-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147680.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">163</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">27</span> The Influence of Collaboration on Individual Writing Quality: The Case of Iranian vs. Malaysian Freshers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Yasin%20Yazdi-Amirkhiz">Seyed Yasin Yazdi-Amirkhiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Azirah%20Hashim"> Azirah Hashim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study purported to comparatively investigate the influence of collaborative writing on the quality of individual writing of four female Iranian and four female Malaysian students. The first semester students at a private university in Malaysia, who were homogeneous in terms of age, gender, study discipline, and language proficiency, were divided into two Iranian and two Malaysian dyads. The dyads performed collaborative writing tasks for 15 sessions; after three consecutive collaborative writing sessions, each participant was asked to individually attempt a writing task. Both collaborative and individual writing tasks comprised isomorphic graphic prompts (IELTS Academic Module task 1). Writing quality of the five individually-produced texts during the study was scored in terms of task achievement (TA), cohesion/coherence (C/C), grammatical range/accuracy (GR/A), and lexical resources (LR). The findings indicated a hierarchy of development in TA and C/C among all the students, while LR showed minor improvement only among three of Malaysian students, and GR/A barely exhibited any progress among all the participants. Intermittent progressions and regressions were also discerned in the trajectory of their writing development. The findings are discussed in the light of the socio-cultural and emergentist perspectives, the typology of tasks used as well as the role of the participants’ level of language proficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collaborative%20writing" title="collaborative writing">collaborative writing</a>, <a href="https://publications.waset.org/abstracts/search?q=writing%20quality" title=" writing quality"> writing quality</a>, <a href="https://publications.waset.org/abstracts/search?q=individual%20writing" title=" individual writing"> individual writing</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration" title=" collaboration"> collaboration</a> </p> <a href="https://publications.waset.org/abstracts/12786/the-influence-of-collaboration-on-individual-writing-quality-the-case-of-iranian-vs-malaysian-freshers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12786.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">458</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">26</span> Burnback Analysis of Star Grain Using Level-Set Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Yasin">Ali Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Kamran"> Ali Kamran</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Safdar"> Muhammad Safdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to reduce the hefty cost involved in terms of time and project cost, the development and application of advanced numerical tools to address the burn-back analysis problem in solid rocket motor design and development is the need of time. Several advanced numerical schemes have been developed in recent times, but their usage in the design of propellant grain of solid rocket motors is very rare. In this paper, an advanced numerical technique named the Level-Set method has been utilized for the burn-back analysis of star grain to study the effect of geometrical parameters on ballistic performance indicators such as solid loading, neutrality, and sliver percentage. In the level set technique, simple finite difference methods may fail quickly and require more sophisticated non-oscillatory schemes for feasible long-time simulation. For internal ballistic calculations, a simplified equilibrium pressure method is utilized. Preliminary results of the operative conditions, for all the combustion time, of star grain burn-back using level set techniques are compared with published results using CAD technique to test the developed numerical model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20rocket%20motor" title="solid rocket motor">solid rocket motor</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20ballistic" title=" internal ballistic"> internal ballistic</a>, <a href="https://publications.waset.org/abstracts/search?q=level-set%20technique" title=" level-set technique"> level-set technique</a>, <a href="https://publications.waset.org/abstracts/search?q=star%20grain" title=" star grain"> star grain</a> </p> <a href="https://publications.waset.org/abstracts/156519/burnback-analysis-of-star-grain-using-level-set-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156519.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">123</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">25</span> Effect of Marginal Quality Groundwater on Yield of Cotton Crop and Soil Salinity Status</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20L.%20Qureshi">A.

In this connection, three irrigation treatments each with four replications were applied. These treatments were use of canal water, use of marginal quality groundwater from tube well, and conjunctive use by mixing with the ratio of 1:1 of canal water and marginal quality tubewell water. Water was applied to the crop cultivated in Kharif season 2011; its quantity has been measured using cut-throat flume. Total 11 watering each of 50 mm depth have been applied from 20th April to 20th July, 2011. Further, irrigations were stopped from last week of July, 2011 due to monsoon rainfall. Maximum crop yield (seed cotton) was observed under T1 which was 1,516.8 kg/ha followed by T3 (mixed canal and tube well water) having 1009 kg/ha and 709 kg/ha for T2 i.e. marginal quality groundwater. This concludes that crop yield in T2 and T3 with in comparison to T1was reduced by about 53 and 30% respectively. It has been observed that yield of cotton crop is below potential limit for three treatments due to unexpected rainfall at the time of full flowering season; thus the yield was adversely affected. However, salt deposition in soil profiles was not observed that is due to leaching effect of heavy rainfall occurred during monsoon season. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conjunctive%20use" title="conjunctive use">conjunctive use</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton%20crop" title=" cotton crop"> cotton crop</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20salinity%20status" title=" soil salinity status"> soil salinity status</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20use%20efficiency" title=" water use efficiency "> water use efficiency </a> </p> <a href="https://publications.waset.org/abstracts/17342/effect-of-marginal-quality-groundwater-on-yield-of-cotton-crop-and-soil-salinity-status" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17342.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">448</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">24</span> Urban and Building Information Modeling’s Applications for Environmental Education: Case Study of Educational Campuses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samar%20Alarif">Samar Alarif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smart sustainable educational campuses are the latest paradigm of innovation in the education domain. Campuses become a hub for sustainable environmental innovations. University has a vital role in paving the road for digital transformations in the infrastructure domain by preparing skilled engineers and specialists. The open digital platform enables smart campuses to simulate real education experience by managing their infrastructure within the curriculums. Moreover, it allows the engagement between governments, businesses, and citizens to push for innovation and sustainable services. Urban and building information modeling platforms have recently attained widespread attention in smart campuses due to their applications and benefits for creating the campus's digital twin in the form of an open digital platform. Qualitative and quantitative strategies were used in directing this research to develop and validate the UIM/BIM platform benefits for smart campuses FM and its impact on the institution's sustainable vision. The research findings are based on literature reviews and case studies of the TU berlin El-Gouna campus. Textual data will be collected using semi-structured interviews with actors, secondary data like BIM course student projects, documents, and publications related to the campus actors. The study results indicated that UIM/BIM has several benefits for the smart campus. Universities can achieve better capacity-building by integrating all the actors in the UIM/BIM process. Universities would achieve their community outreach vision by launching an online outreach of UIM/BIM course for the academic and professional community. The UIM/BIM training courses would integrate students from different disciplines and alumni graduated as well as engineers and planners and technicians. Open platforms enable universities to build a partnership with the industry; companies should be involved in the development of BIM technology courses. The collaboration between academia and the industry would fix the gap, promote the academic courses to reply to the professional requirements, and transfer the industry's academic innovations. In addition to that, the collaboration between academia, industry, government vocational and training centers, and civil society should be promoted by co-creation workshops, a series of seminars, and conferences. These co-creation activities target the capacity buildings and build governmental strategies and policies to support expanding the sustainable innovations and to agree on the expected role of all the stakeholders to support the transformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title="smart city">smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20educational%20campus" title=" smart educational campus"> smart educational campus</a>, <a href="https://publications.waset.org/abstracts/search?q=UIM" title=" UIM"> UIM</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20platforms" title=" urban platforms"> urban platforms</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20campus" title=" sustainable campus"> sustainable campus</a> </p> <a href="https://publications.waset.org/abstracts/136590/urban-and-building-information-modelings-applications-for-environmental-education-case-study-of-educational-campuses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136590.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">123</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">23</span> Major Depressive Disorder: Diagnosis based on Electroencephalogram Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wajid%20Mumtaz">Wajid Mumtaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamir%20Saeed%20Malik"> Aamir Saeed Malik</a>, <a href="https://publications.waset.org/abstracts/search?q=Syed%20Saad%20Azhar%20Ali"> Syed Saad Azhar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Azhar%20Mohd%20Yasin"> Mohd Azhar Mohd Yasin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a technique based on electroencephalogram (EEG) analysis is presented, aiming for diagnosing major depressive disorder (MDD) among a potential population of MDD patients and healthy controls. EEG is recognized as a clinical modality during applications such as seizure diagnosis, index for anesthesia, detection of brain death or stroke. However, its usability for psychiatric illnesses such as MDD is less studied. Therefore, in this study, for the sake of diagnosis, 2 groups of study participants were recruited, 1) MDD patients, 2) healthy people as controls. EEG data acquired from both groups were analyzed involving inter-hemispheric asymmetry and composite permutation entropy index (CPEI). To automate the process, derived quantities from EEG were utilized as inputs to classifier such as logistic regression (LR) and support vector machine (SVM). The learning of these classification models was tested with a test dataset. Their learning efficiency is provided as accuracy of classifying MDD patients from controls, their sensitivities and specificities were reported, accordingly (LR =81.7 % and SVM =81.5 %). Based on the results, it is concluded that the derived measures are indicators for diagnosing MDD from a potential population of normal controls. In addition, the results motivate further exploring other measures for the same purpose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=major%20depressive%20disorder" title="major depressive disorder">major depressive disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis%20based%20on%20EEG" title=" diagnosis based on EEG"> diagnosis based on EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG%20derived%20features" title=" EEG derived features"> EEG derived features</a>, <a href="https://publications.waset.org/abstracts/search?q=CPEI" title=" CPEI"> CPEI</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-hemispheric%20asymmetry" title=" inter-hemispheric asymmetry"> inter-hemispheric asymmetry</a> </p> <a href="https://publications.waset.org/abstracts/22303/major-depressive-disorder-diagnosis-based-on-electroencephalogram-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22303.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">546</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">22</span> Asynchronous Low Duty Cycle Media Access Control Protocol for Body Area Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Ghasemi-Zadeh">Yasin Ghasemi-Zadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yousef%20Kavian"> Yousef Kavian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wireless body area networks (WBANs) technology has achieved lots of popularity over the last decade with a wide range of medical applications. This paper presents an asynchronous media access control (MAC) protocol based on B-MAC protocol by giving an application for medical issues. In WBAN applications, there are some serious problems such as energy, latency, link reliability (quality of wireless link) and throughput which are mainly due to size of sensor networks and human body specifications. To overcome these problems and improving link reliability, we concentrated on MAC layer that supports mobility models for medical applications. In the presented protocol, preamble frames are divided into some sub-frames considering the threshold level. Actually, the main reason for creating shorter preambles is the link reliability where due to some reasons such as water, the body signals are affected on some frequency bands and causes fading and shadowing on signals, therefore by increasing the link reliability, these effects are reduced. In case of mobility model, we use MoBAN model and modify that for some more areas. The presented asynchronous MAC protocol is modeled by OMNeT++ simulator. The results demonstrate increasing the link reliability comparing to B-MAC protocol where the packet reception ratio (PRR) is 92% also covers more mobility areas than MoBAN protocol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20body%20area%20networks%20%28WBANs%29" title="wireless body area networks (WBANs)">wireless body area networks (WBANs)</a>, <a href="https://publications.waset.org/abstracts/search?q=MAC%20protocol" title=" MAC protocol"> MAC protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=link%20reliability" title=" link reliability"> link reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=mobility" title=" mobility"> mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=biomedical" title=" biomedical"> biomedical</a> </p> <a href="https://publications.waset.org/abstracts/62759/asynchronous-low-duty-cycle-media-access-control-protocol-for-body-area-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62759.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">369</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">21</span> Study on Developmental and Pathogenesis Related Genes Expression Deregulation in Brassica compestris Infected with 16Sr-IX Associated Phytoplasma </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samina%20Jam%20Nazeer%20Ahmad">Samina Jam Nazeer Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20%20Yasin"> Samia Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijaz%20Ahmad"> Ijaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Tahir"> Muhammad Tahir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jam%20Nazeer%20Ahmad"> Jam Nazeer Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phytoplasmas are phloem-inhibited plant pathogenic bacteria that are transferred by insect vectors. Among biotic factors, Phytoplasma infection induces abnormality influencing the physiology as well as morphology of plants. In 16Sr-IX group phytoplasma-infected brassica compestris, flower abnormalities have been associated with changes in the expression of floral development genes. To determine whether methylation was involved in down-regulation of flower development, the process of DNA methylation and Demethylation was investigated as a possible mechanism for regulation of floral gene expression in phytoplasma infected Brassica transmitted by Orosious orientalis vector by using RT-PCR, MSRE-PCR, Southern blotting, Bisulfite Sequencing, etc. Transcriptional expression of methylated genes was found to be globally down-regulated in plants infected with phytoplasma, but not severely in those infested by insect vectors and variation in expression was found in genes involved in methylation. These results also showed that genes particularly orthologous to Arabidopsis APETALA3 involved in petal formation and flower development was down-regulated severely in phytoplasma-infected brassica and with the fact that phytoplasma and insect induce variation in developmental gene expression. The DNA methylation status of flower developmental gene in phytoplasma infected plants with 5-azacytidine restored gene expression strongly suggesting that DNA methylation was involved in down-regulation of floral development genes in phytoplasma infected brassica. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genes%20expression" title="genes expression">genes expression</a>, <a href="https://publications.waset.org/abstracts/search?q=phytoplasma" title=" phytoplasma"> phytoplasma</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20methylation" title=" DNA methylation"> DNA methylation</a>, <a href="https://publications.waset.org/abstracts/search?q=flower%20development" title=" flower development"> flower development</a> </p> <a href="https://publications.waset.org/abstracts/87401/study-on-developmental-and-pathogenesis-related-genes-expression-deregulation-in-brassica-compestris-infected-with-16sr-ix-associated-phytoplasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87401.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">374</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">20</span> Analysis of Solvent Effect on the Mechanical Properties of Poly(Ether Ether Ketone) Using Nano-Indentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanveer%20Iqbal">Tanveer Iqbal</a>, <a href="https://publications.waset.org/abstracts/search?q=Saima%20Yasin"> Saima Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Zafar"> Muhammad Zafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Shakeel"> Ahmad Shakeel</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Nazir"> Fahad Nazir</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20F.%20Luckham"> Paul F.

This is particularly important for fiber oriented polymeric materials where self-lubrication from top layers has been the basic requirement. The nanoindentation response of fiber reinforced poly(etheretherketone), PEEK, composites have been evaluated to determine the near-surface mechanical characteristics. Load-displacement compliance, hardness and elastic modulus data based on contact compliance mode (CSM) indentation of carbon fiber oriented and glass fiber oriented PEEK composites are reported as a function of indentation contact displacement. The composite surfaces were indented to a maximum penetration depth of 5µm using Berkovich tip indenter. A typical multiphase response of the composite surface is depicted from analysis of the indentation data for the composites, showing presence of polymer matrix, fibers, and interphase regions. The observed experimental results show that although the surface mechanical properties of carbon fiber based PEEK composite were comparatively higher, the properties of matrix material were seen to be increased in the presence of glass fibers. The experimental methodology may provide a convenient means to understand morphological description of the multimodal polymeric composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoindentation" title="nanoindentation">nanoindentation</a>, <a href="https://publications.waset.org/abstracts/search?q=PEEK" title=" PEEK"> PEEK</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus" title=" modulus"> modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticization" title=" plasticization"> plasticization</a> </p> <a href="https://publications.waset.org/abstracts/78722/analysis-of-solvent-effect-on-the-mechanical-properties-of-polyether-ether-ketone-using-nano-indentation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78722.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">192</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">19</span> Active Food Packaging Films Based on Functionalized Graphene/Polymer Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Ghanem">Ahmad Ghanem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Yasin"> Mohamad Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mona%20Abdel%20Rehim"> Mona Abdel Rehim</a>, <a href="https://publications.waset.org/abstracts/search?q=Fabrice%20Gouanve"> Fabrice Gouanve</a>, <a href="https://publications.waset.org/abstracts/search?q=Eliane%20Espuche"> Eliane Espuche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biodegradable polymers are of great interest, especially for biomedical and packaging applications. Current research efforts are focused on the development of biopolymers with the purpose of reducing the plastic pollution induced by the widely used in biodegradable polyolefins. The main challenge is focused on the elaboration of biopolymers having properties competitive to those of polyolefins. On the other hand, graphene oxide (GO), a graphene derivative, is characterized by the presence of several functional groups on the surface such as carboxylic, hydroxyl and epoxide. This feature enables modification of GO surface with different modifiers to obtain versatile surface properties and overcome the problem of graphene sheets aggregations during inclusion in a polymer matrix. In this context, poly (butylene succinate) (PBS) as promising biopolyester is modified through blending with different ratios of functionalized (GO) to improve its barrier properties. Modification of GO has been carried out using different hyperbranched polymeric structures in order to increase miscibility of the nanosheets in the hosting polymeric matrix. Films have been prepared from the modified PBS and their mechanical, thermal and gas barrier properties were investigated. The results reveal enhancement in the thermal and mechanical properties beside observed improvement of the barrier properties for the films prepared from the modified PBS. This improvement is related to the strong dependence on tortuosity effects of dispersion, exfoliation levels of fillers into the polymer matrix and interactions between the fillers and the polymer matrix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20barrier%20properties" title="gas barrier properties">gas barrier properties</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20oxide" title=" graphene oxide"> graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20packaging" title=" food packaging"> food packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20properties" title=" transport properties"> transport properties</a> </p> <a href="https://publications.waset.org/abstracts/98378/active-food-packaging-films-based-on-functionalized-graphenepolymer-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98378.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">235</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">18</span> Some Remains of Fossil Artiodactyla: Evolutionary Status, Taxonomy and Biogeographical Distribution in Late Miocene of Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khizar%20Samiullah%20Samiullah">Khizar Samiullah Samiullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Riffat%20Yasin"> Riffat Yasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Khurrum%20Feroz"> Khurrum Feroz</a>, <a href="https://publications.waset.org/abstracts/search?q=Omer%20Draz"> Omer Draz</a>, <a href="https://publications.waset.org/abstracts/search?q=Memmona%20Nazish"> Memmona Nazish</a> </p> <p class="card-text"><strong>Abstract:</strong></p> New fossil remains of artiodactyl have been recovered from three Late Miocene localities, Lava, Dhok Bun Ameer Khatoon and Hasnoot. These localities belong to lower and middle Siwalik Hills of Pakistan, the Chinji and Dhok Pathan Formation respectively and are remarkably rich in fossils of artiodactyl. The fauna mainly comprises various families of order Artiodactyla; Cervidae, Equidea, Proboscidea, Giraffidea, Rhinocerotidae, Tragulidea, Suidae and Primates. In Chinji Formation Lava and Dhok Bun Ameer Khatoon are located in district Chakwal while in Upper Dhok Pathan Formation the best fossils exposure site is Hasnoot which is located in District Jhelum, Punjab, Pakistan. Specimens described and discussed here include right and left maxilla, isolated upper premolars and molars which have been collected during extensive fieldwork. After morphological and comparative analysis the collection is attributed to Giraffokeryx, Giraffa, Listriodon, Dorcatherium, Selenoportax and Pachyportax. In this study evolutionary status, taxonomy and biogeographical distribution as well as the relationship of different Artiodactyls have been discussed comprehensively. The Palaeoenvironmental studies reveal the persistence of mosaics of diverse habitats ranging from tropical evergreen forest to subtropical ones, closed seasonal woodlands to wooded savannas during the deposition of these outcrops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artiodactyla" title="Artiodactyla">Artiodactyla</a>, <a href="https://publications.waset.org/abstracts/search?q=fossil%20dentition" title=" fossil dentition"> fossil dentition</a>, <a href="https://publications.waset.org/abstracts/search?q=late%20Miocene" title=" late Miocene"> late Miocene</a>, <a href="https://publications.waset.org/abstracts/search?q=lower%20and%20middle%20Siwaliks" title=" lower and middle Siwaliks"> lower and middle Siwaliks</a> </p> <a href="https://publications.waset.org/abstracts/57354/some-remains-of-fossil-artiodactyla-evolutionary-status-taxonomy-and-biogeographical-distribution-in-late-miocene-of-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57354.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">259</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">17</span> Awareness of Drug Interactions among Physicians at Governmental Health Centers in Bahrain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20I.%20Tayem">Yasin I.

The rate of DDIs is rapidly increasing worldwide with the increasing proportion of ageing population and frequent requirement of polypharmacy-prescription of multiple drugs to treat comorbidities. Prescribing physicians are responsible for checking their prescriptions for the presence and severity of DDIs. However, since a large number of new drugs are approved and marketed every year, new interactions between medications are increasingly reported. Consequently, it is no longer practical for physicians to rely only upon their previous knowledge of medicine to avoid potential DDIs. The aim of this study was to explore the perceptions of physicians working at primary healthcare centers in Bahrain towards DDIs and how they manage them during their practice. Methodology: In this cross-sectional study, physicians working at all governmental primary healthcare centers in Bahrain were invited to voluntarily, privately and anonymously respond to a self-administered questionnaire. The questionnaire aims to assess their self-reported knowledge of DDIs and how they check for them in their practice. The participants were requested to provide socio demographic data and information related to their attitudes towards DDIs including strategies they employ for detecting and managing them, and their awareness of drugs which commonly cause DDIs. At the end of the questionnaire, an open-ended item was added to allow participants to further add any comment. Findings and Conclusions: The study is going on currently, and the results and conclusions will be presented at the conference. <p class="card-text"><strong>Keywords:</strong> <a
