the previous work done with ARS-680 Environmental Chamber. Drying is a complex operation that demands much energy and time. Drying is essentially important for preservation of ginger rhizome. Drying of ginger was modeled, and then the effective diffusion coefficient and activation energy where determined. For this purpose, the experiments were done at six levels of varied temperature ranging from (10, 20, 30, 40, 50, 60°C). The average effective diffusion coefficient for their studies samples for temperature range of 40°C to 70°C was 4.48 x10-10m²/s, 4.96 x10-10m²/s, and 5.31 x10-10m²/s for 0.8, 1.5 and 3m/s drying air velocity respectively. These values closely agreed with the values of effective diffusion coefficients obtained in these studies for the variously treated ginger rhizomes and test conducted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activation%20energy" title="activation energy">activation energy</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion%20coefficients" title=" diffusion coefficients"> diffusion coefficients</a>, <a href="https://publications.waset.org/abstracts/search?q=drying%20model" title=" drying model"> drying model</a>, <a href="https://publications.waset.org/abstracts/search?q=drying%20time" title=" drying time"> drying time</a>, <a href="https://publications.waset.org/abstracts/search?q=ginger%20rhizomes" title=" ginger rhizomes"> ginger rhizomes</a>, <a href="https://publications.waset.org/abstracts/search?q=moisture%20ratio" title=" moisture ratio"> moisture ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20layer" title=" thin layer"> thin layer</a> </p> <a href="https://publications.waset.org/abstracts/120153/determination-of-natural-logarithm-of-diffusion-coefficient-and-activation-energy-of-thin-layer-drying-process-of-ginger-rhizome-slices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120153.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">166</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">68</span> Design, Analysis and Construction of a 250vac 8amps Arc Welding Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anthony%20Okechukwu%20Ifediniru">Anthony Okechukwu Ifediniru</a>, <a href="https://publications.waset.org/abstracts/search?q=Austin%20Ikechukwu%20Gbasouzor"> Austin Ikechukwu Gbasouzor</a>, <a href="https://publications.waset.org/abstracts/search?q=Isidore%20Uche%20Uju"> Isidore Uche Uju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article is centered on the design, analysis, construction, and test of a locally made arc welding machine that operates on 250vac with 8 amp output taps ranging from 60vac to 250vac at a fixed frequency, which is of benefit to urban areas; while considering its cost-effectiveness, strength, portability, and mobility. The welding machine uses a power supply to create an electric arc between an electrode and the metal at the welding point. A current selector coil needed for current selection is connected to the primary winding. Electric power is supplied to the primary winding of its transformer and is transferred to the secondary winding by induction. The voltage and current output of the secondary winding are connected to the output terminal, which is used to carry out welding work. The output current of the machine ranges from 110amps for low current welding to 250amps for high current welding. The machine uses a step-down transformer configuration for stepping down the voltage in order to obtain a high current level for effective welding. The welder can adjust the output current within a certain range. This allows the welder to properly set the output current for the type of welding that is being performed. The constructed arc welding machine was tested by connecting the work piece to it. Since there was no shock or spark from the transformer’s laminated core and was successfully used to join metals, it confirmed and validated the design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AC%20current" title="AC current">AC current</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20welding%20machine" title=" arc welding machine"> arc welding machine</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20current" title=" DC current"> DC current</a>, <a href="https://publications.waset.org/abstracts/search?q=transformer" title=" transformer"> transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=welds" title=" welds"> welds</a> </p> <a href="https://publications.waset.org/abstracts/125450/design-analysis-and-construction-of-a-250vac-8amps-arc-welding-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125450.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">181</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">67</span> A Look Back at America’s Transit History and the Impacts of Household Income on Walkability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jackson%20Becker">Jackson Becker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transportation produces the largest amount of carbon dioxide emissions in the United States of America. Today, cars are the predominant mode of transportation across the country, and our cities have been reshaped due to them. This was not always the case. Streetcars were seen in almost every American city of the early 1900s. These streetcar systems were viewed as obsolete with the rise of the automobile. With fewer streetcars came lower public transport ridership. Austin, Texas is one of the fastest growing cities in the country, and it used to have an extensive streetcar line. Today, it plans to build a light rail line with less rail mileage than 100 years ago. This research looks at the areas of Austin that are not included in the city’s new transit plan. Transit connectivity is one factor that goes into walkability rates for cities. This study also looks at the correlation between walkability ratings with median household income levels from the 2019 Census. The results showed a correlation between higher income neighborhoods having higher walkability rates, which was influenced by the lack of public transportation options. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transportation" title="transportation">transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=walkability" title=" walkability"> walkability</a>, <a href="https://publications.waset.org/abstracts/search?q=income" title=" income"> income</a>, <a href="https://publications.waset.org/abstracts/search?q=austin" title=" austin"> austin</a> </p> <a href="https://publications.waset.org/abstracts/191382/a-look-back-at-americas-transit-history-and-the-impacts-of-household-income-on-walkability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191382.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">13</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">66</span> A Framework and Case Study for Sustainable Development of Urban Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasaman%20Zeinali">Yasaman Zeinali</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Khosravikia"> Farid Khosravikia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a multi-objective framework for sustainable urban development. The proposed framework aims to address different aspects of sustainability in urban development planning. These aspects include, but are not limited to education, health, job opportunities, architecture, culture, environment, mobility, energy, water, waste, and so on. Then, the proposed framework is applied to the Brackenridge Tract (an area in downtown Austin, Texas), to redevelop that area in a sustainable way. The detail of the implementation process is presented in this paper. The ultimate goal of this paper is to develop a sustainable area in downtown Austin with ensuring that it locally meets the needs of present and future generations with respect to economic, social, environmental, health as well as cultural aspects. Moreover, it helps the city with the population growth problem by accommodating more people in that area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20planning" title="urban planning">urban planning</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20development" title=" sustainable urban development"> sustainable urban development</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts%20of%20human%20activities" title=" environmental impacts of human activities"> environmental impacts of human activities</a> </p> <a href="https://publications.waset.org/abstracts/111328/a-framework-and-case-study-for-sustainable-development-of-urban-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111328.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">253</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">65</span> Wastewater Treatment Using Microalgae</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chigbo%20Ikechukwu%20Emmanuel">Chigbo Ikechukwu Emmanuel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microalgae can be used for tertiary treatment of wastewater due to their capacity to assimilate nutrients. The pH increase which is mediated by the growing algae also induces phosphorus precipitation and ammonia stripping to the air, and may in addition act disinfecting on the wastewater. Domestic wastewater is ideal for algal growth since it contains high concentrations of all necessary nutrients. The growth limiting factor is rather light, especially at higher latitudes. The most important operational factors for successful wastewater treatment with microalgae are depth, turbulence and hydraulic retention time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microalgae" title="microalgae">microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus" title=" phosphorus"> phosphorus</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen" title=" nitrogen"> nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=light" title=" light"> light</a>, <a href="https://publications.waset.org/abstracts/search?q=operation" title=" operation"> operation</a>, <a href="https://publications.waset.org/abstracts/search?q=ponds" title=" ponds"> ponds</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a> </p> <a href="https://publications.waset.org/abstracts/15818/wastewater-treatment-using-microalgae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15818.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">478</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">64</span> Global Learning Supports Global Readiness with Projects with Purpose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brian%20Bilich">Brian Bilich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A typical global learning program is a two-week project based, culturally immersive and academically relevant experience built around a project with purpose and catered to student and business groups. Global Learning in Continuing Education at Austin Community College promotes global readiness through projects with purpose with special attention given to balancing learning, hospitality and travel. A recent project involved CommunityFirst! Village; a 51-acre planned community which provides affordable, permanent housing for men and women coming out of chronic homelessness. Global Learning students collaborated with residents and staff at the Community First! Village on a project to produce two-dimensional remodeling plans of residents’ tiny homes with a focus on but not limited to design improvements on elements related to accessibility, increased usability of living and storage space and esthetic upgrades to boost psychological and emotional appeal. The goal of project-based learning in the context of global learning in Continuing Educaiton at Austin Community Collegen general is two fold. One, in rapid fashion we develop a project which gives the learner a hands-on opportunity to exercise soft and technical skills, like creativity and communication and analytical thinking. Two, by basing projects on global social conflict issues, the project of purpose promotes the development of empathy for other people and fosters a sense of corporate social responsibility in future generations of business leadership. In the example provide above the project informed the student group on the topic of chronic homelessness and promoted awareness and empathy for this underserved segment of the community. Project-based global learning based on projects with purpose has the potential to cultivate global readiness by developing empathy and strengthening emotional intelligence for future generations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=project-based%20learning" title="project-based learning">project-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20learning" title=" global learning"> global learning</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20readiness" title=" global readiness"> global readiness</a>, <a href="https://publications.waset.org/abstracts/search?q=globalization" title=" globalization"> globalization</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20exchange" title=" international exchange"> international exchange</a>, <a href="https://publications.waset.org/abstracts/search?q=collaboration" title=" collaboration"> collaboration</a> </p> <a href="https://publications.waset.org/abstracts/175797/global-learning-supports-global-readiness-with-projects-with-purpose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175797.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">64</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">63</span> Health Hazards of Performance Enhancing Drugs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Austin%20Oduor%20Otieno">Austin Oduor Otieno</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is an ingrained belief that the use of performance-enhancing drugs by athletes enable them to perform better.

This interference is considered a serious problem in second language learning. Usually, the interference has been phonological. But the objective of this research is to explore how the target language interferes with the mother tongue. In the case of the Igbo language, it interferes with English mostly at the phonological level while English interferes with Igbo at the realm of vocabulary. The result is a new language \"Engligbo\" which is a hybrid of English and Igbo. The Igbo language spoken by about 25 million people is one of the three most prominent languages in Nigeria. This paper discusses the phenomenal Engligbo, and other implications for Igbo learners of English. The method of analysis is descriptive. A number of recommendations were made that would help teachers handle problems arising from such mutual interferences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reciprocal%20interferences" title="reciprocal interferences">reciprocal interferences</a>, <a href="https://publications.waset.org/abstracts/search?q=bilingualism" title=" bilingualism"> bilingualism</a>, <a href="https://publications.waset.org/abstracts/search?q=implications" title=" implications"> implications</a>, <a href="https://publications.waset.org/abstracts/search?q=language%20pedagogy" title=" language pedagogy "> language pedagogy </a> </p> <a href="https://publications.waset.org/abstracts/3835/reciprocal-interferences-in-bilingual-english-igbo-speaking-society-the-implications-in-language-pedagogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3835.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">398</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">61</span> Ionic Liquid Effects on Metal Ion-Based Extractions of Olefin/Paraffin Hydrocarbon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ellen%20M.%20Lukasik">Ellen M.

To introduce the concepts of this research in high school education, a lesson plan was developed to instruct students on the principles of liquid-liquid separation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ionic%20liquids" title="ionic liquids">ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid-liquid%20separation" title=" liquid-liquid separation"> liquid-liquid separation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon" title=" hydrocarbon"> hydrocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20experience%20for%20teachers" title=" research experience for teachers"> research experience for teachers</a> </p> <a href="https://publications.waset.org/abstracts/153896/ionic-liquid-effects-on-metal-ion-based-extractions-of-olefinparaffin-hydrocarbon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153896.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">105</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">60</span> Assessment of the Relationship Between Energy Price Dynamics and Green Growth in Sub-Saharan Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Ikechukwu%20Ifeacho">Christopher Ikechukwu Ifeacho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper examines the relationship between energy price dynamics and green growth in Sub Sahara African Countries. The quest for adopting green energy in order to improve the green growth that can engender sustainability, and stability has received more attention from researchers in recent times. This study uses a panel Autoregressive distributed lag approach to investigate this relationship. Findings from the result showed that energy price dynamics and exchange rate have more short-run significant impacts on green growth in individual countries rather than the pooled result. Furthermore, the long-run result confirmed that inflation and capital have a significant long-run relationship with green growth. The causality test result revealed the existence of a bi-directional relationship between green growth and energy price dynamics. The study recommends caution in a currency devaluation and improvement in renewable energy production in the Sub Sahara Africa in order to achieve sustainable green growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20growth" title="green growth">green growth</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20price%20dynamics" title=" energy price dynamics"> energy price dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=Sub%20Sahara%20Africa." title=" Sub Sahara Africa."> Sub Sahara Africa.</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/192159/assessment-of-the-relationship-between-energy-price-dynamics-and-green-growth-in-sub-saharan-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192159.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">21</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">59</span> Improving the Ability of Constructed Wetlands to Treat Acid Mine Drainage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chigbo%20Emmanuel%20Ikechukwu">Chigbo Emmanuel Ikechukwu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Constructed wetlands are seen as a potential means of ameliorating the poor quality water that derives from coal and gold mining operations. However, the processes whereby a wetland environment is able to improve water quality are not well understood and techniques for optimising their performance poorly developed. A parameter that may be manipulated in order to improve the treatment capacity of a wetland is the substrate in which the aquatic plants are rooted. This substrate can provide an environment wherein sulphate reducing bacteria, which contribute to the removal of contaminants from the water, are able to flourish. The bacteria require an energy source which is largely provided by carbon in the substrate. This paper discusses the form in which carbon is most suitable for the bacteria and describes the results of a series of experiments in which different materials were used as substrate. Synthetic acid mine drainage was passed through an anaerobic bioreactor that contained either compost or cow manure. The effluent water quality was monitored with respect to time and the effect of the substrate composition discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructed%20wetland" title="constructed wetland">constructed wetland</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon" title=" carbon"> carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20mine%20drainage" title=" acid mine drainage"> acid mine drainage</a>, <a href="https://publications.waset.org/abstracts/search?q=sulphate" title=" sulphate"> sulphate</a> </p> <a href="https://publications.waset.org/abstracts/20207/improving-the-ability-of-constructed-wetlands-to-treat-acid-mine-drainage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20207.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">440</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">58</span> Subsea Control Module (SCM) - A Vital Factor for Well Integrity and Production Performance in Deep Water Oil and Gas Fields</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Okoro%20Ikechukwu%20Ralph">Okoro Ikechukwu Ralph</a>, <a href="https://publications.waset.org/abstracts/search?q=Fuat%20Kara"> Fuat Kara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The discoveries of hydrocarbon reserves has clearly drifted offshore, and in deeper waters - areas where the industry still has limited knowledge; and that were hitherto, regarded as being out of reach. This shift presents significant and increased challenges in technology requirements needed to guarantee safety of personnel, environment and equipment; ensure high reliability of installed equipment; and provide high level of confidence in security of investment and company reputation. Nowhere are these challenges more apparent than on subsea well integrity and production performance. The past two decades has witnessed enormous rise in deep and ultra-deep water offshore field developments for the recovery of hydrocarbons. Subsea installed equipment at the seabed has been the technology of choice for these developments.

Organisations all over the world are moving their computing services towards the cloud this is because of its rapid transformation of the organization’s infrastructure and improvement of efficient resource utilization and cost reduction. However, this technology brings new security threats and challenges about safety, reliability and data confidentiality. Evidently, no single security technique can guarantee security or protection against malicious attacks on a cloud computing network hence an integrated model of intrusion detection and prevention system has been proposed. Anomaly-based and signature-based detection techniques will be integrated to enable the network and its host defend themselves with some level of intelligence. The anomaly-base detection was implemented using the local deviation factor graph-based (LDFGB) algorithm while the signature-based detection was implemented using the snort algorithm. Results from this collaborative intrusion detection and prevention techniques show robust and efficient security architecture for cloud computing networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anomaly-based%20detection" title="anomaly-based detection">anomaly-based detection</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title=" cloud computing"> cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=intrusion%20detection" title=" intrusion detection"> intrusion detection</a>, <a href="https://publications.waset.org/abstracts/search?q=intrusion%20prevention" title=" intrusion prevention"> intrusion prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=signature-based%20detection" title=" signature-based detection"> signature-based detection</a> </p> <a href="https://publications.waset.org/abstracts/89892/intrusion-detection-and-prevention-system-idps-in-cloud-computing-using-anomaly-based-and-signature-based-detection-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89892.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">305</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">56</span> Location Privacy Preservation of Vehicle Data In Internet of Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying%20Ying%20Liu">Ying Ying Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Austin%20Cooke"> Austin Cooke</a>, <a href="https://publications.waset.org/abstracts/search?q=Parimala%20Thulasiraman"> Parimala Thulasiraman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Internet of Things (IoT) has attracted a recent spark in research on Internet of Vehicles (IoV).

This paper discusses an innovative device that could be used as part of the smart city initiative to detect and provide alerts in case of floods at road crossings and wildfires. An Internet of Things (IoT) smart city node was designed, tested, and deployed with collaboration from the City of Austin. The end to end solution includes a 3G enabled IoT device, flood and fire sensors, cloud, a mobile app, and IoT analytics. The real-time data was collected and analyzed using IoT analytics to refine the solution for the past year.

The challenge here is for everyone who practices agriculture as an income generating activity in Cameroon to be able to understand the concept of value-added products and to know how to go about it. Recent studies have shown that these farmers who depend on agriculture as their main income generation activity make a great loss out of it because they don’t have the means to either transport their produce to the appropriate market, they don’t the knowledge on how to transform it, or they don’t have a means of conserving the product for a longer duration. It is important to note that after a thorough evaluation of the activity carried out, the final added value product sold is of great benefit not only to the producer but the buyer and the population at large. In my proposed prestation, I will discuss how the transformation activity will have a positive impact on the lives of farmers and the buyers and, most importantly, describe the methodology and procedure which is followed before the tubers (banana, Plantain, potato)is transformed into the finished or semi-finished product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=transformation" title="transformation">transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=consumption" title=" consumption"> consumption</a> </p> <a href="https://publications.waset.org/abstracts/157746/transformation-of-potato-plantain-banana-to-flour-in-order-to-enhance-sustainable-development-and-promote-local-consumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157746.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">103</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">52</span> Using Fishers Knowledge in Community Based Fisheries Management in River Nun Estuary, Niger Delta</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabina%20Ngodigha">Sabina Ngodigha</a>, <a href="https://publications.waset.org/abstracts/search?q=Roland%20Gbarabe"> Roland Gbarabe</a>, <a href="https://publications.waset.org/abstracts/search?q=Aiyebatonworio%20Austin"> Aiyebatonworio Austin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A study of fisher’s knowledge (FK) and community-based fisheries management practices in River Nun estuary was conducted to assess the contribution of FK to fisheries resources conservation. A total of 390 fishers operates in the area of which 221 were interviewed based on having a minimum of 10 years of experience. Community-based fisheries management programme was introduced and implemented by fishermen’s union in 2010 for the sustainable management and conservation of fisheries resources. Local law introduced were: band on the use of mesh size of less than 5cm and band on chemical fishing. Defaulters were made to pay monetary fines ranging from #2,000 to #6,000 while fishers caught using chemicals to fish were arrested and landed over to the police for prosecution. The management method has enhanced conservation of fisheries resources which is a major source of livelihood for the people. Landings increased tremendously resulting in positive increase in the finances of the fishers. It is, therefore, pertinent to introduce community-based laws to check over exploitation of fisheries resources in the Niger Delta. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community" title="community">community</a>, <a href="https://publications.waset.org/abstracts/search?q=conservation" title=" conservation"> conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=fishers%20knowledge" title=" fishers knowledge"> fishers knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20laws" title=" local laws"> local laws</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/56294/using-fishers-knowledge-in-community-based-fisheries-management-in-river-nun-estuary-niger-delta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56294.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">277</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">51</span> Optimization of the Production Processes of Biodiesel from a Locally Sourced Gossypium herbaceum and Moringa oleifera</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ikechukwu%20Ejim">Ikechukwu Ejim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research project addresses the optimization of biodiesel production from gossypium herbaceum (cottonseed) and moringa oleifera seeds. Soxhlet extractor method using n-hexane for gossypium herbaceum (cottonseed) and ethanol for moringa oleifera were used for solvent extraction. 1250 ml of oil was realized from both gossypium herbaceum (cottonseed) and moringa oleifera seeds before characterization. In transesterification process, a 4-factor-3-level experiment was conducted using an optimal design of Response Surface Methodology. The effects of methanol/oil molar ratio, catalyst concentration (%), temperature (°C) and time (mins), on the yield of methyl ester for both cottonseed and moringa oleifera oils were determined. The design consisted of 25 experimental runs (5 lack of fit points, five replicate points, 0 additional center points and I optimality) and provided sufficient information to fit a second-degree polynomial model. The experimental results suggested that optimum conditions were as follows; cottonseed yield (96.231%), catalyst concentration (0.972%), temperature (55oC), time (60mins) and methanol/oil molar ratios (8/1) respectively while moringa oleifera optimum values were yield (80.811%), catalyst concentration (1.0%), temperature (54.7oC), time (30mins ) and methanol/oil molar ratios (8/1) respectively. This optimized conditions were validated with the actual biodiesel yield in experimental trials and literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Gossypium%20herbaceum" title=" Gossypium herbaceum"> Gossypium herbaceum</a>, <a href="https://publications.waset.org/abstracts/search?q=Moringa%20oleifera" title=" Moringa oleifera"> Moringa oleifera</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title=" biodiesel"> biodiesel</a> </p> <a href="https://publications.waset.org/abstracts/94652/optimization-of-the-production-processes-of-biodiesel-from-a-locally-sourced-gossypium-herbaceum-and-moringa-oleifera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94652.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">145</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">50</span> Safety Effect of Smart Right-Turn Design at Intersections </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Upal%20Barua">Upal Barua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The risk of severe crashes at high-speed right-turns at intersections is a major safety concern these days. The application of a smart right-turn at an intersection is increasing day by day to address is an issue. The design, ‘Smart Right-turn’ consists of a narrow-angle of channelization at approximately 70°. This design increases the cone of vision of the right-tuning drivers towards the crossing pedestrians as well as traffic on the cross-road. As part of the Safety Improvement Program in Austin Transportation Department, several smart right-turns were constructed at high crash intersections where high-speed right-turns were found to be a contributing factor.

Freshly processed rice husk in Mandle’s medium were heat pre-treated using an autoclave at 121oC for 20 minutes. The isolated fungi as monoculture and di-culture combinations were inoculated into each of the pre-treated rice husk with the exception of two controls. Seven days hydrolysis was followed by estimation of carbohydrate, reducing sugar and non-reducing sugar. Fungal treated rice husks were left to ferment for 7 days with introduction of both baker’s and palm wine yeast. The result obtained in the work gave the highest carbohydrate (20.53 ± 2.73 %) from rice husks treated with TS + TR di-culture. The highest soluble reducing sugar (2.66 ± 0.14 %) was obtained from rice husk treated with TM. The highest soluble nonreducing sugar (18.08 ± 2.61 %) was from AF. The introduction of yeasts from palm wine gave the highest bio-ethanol (12.82 ± 0.39 %) from AO. The highest bio-ethanol (6.60 ± 0.10 %) from baker's yeast fermentation was in AO + TS treated rice husk. There was increased availability of sugar and moderate yield of bio-ethanol, especially from palm wine yeast. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungi" title="fungi">fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20husk" title=" rice husk"> rice husk</a>, <a href="https://publications.waset.org/abstracts/search?q=carbohydrate" title=" carbohydrate"> carbohydrate</a>, <a href="https://publications.waset.org/abstracts/search?q=reducing%20sugar" title=" reducing sugar"> reducing sugar</a>, <a href="https://publications.waset.org/abstracts/search?q=non-reducing%20sugar" title=" non-reducing sugar"> non-reducing sugar</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a> </p> <a href="https://publications.waset.org/abstracts/27558/fermentable-bio-ethanol-using-bakers-and-palmwine-yeasts-indices-of-bioavailability-of-carbohydrate-and-sugar-from-fungal-treated-rice-husk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27558.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">440</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">48</span> Dietary Gluten and the Balance of Gut Microbiota in the Dextran Sulphate Sodium Induced Colitis Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Austin%20Belfiori">Austin Belfiori</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Rinek"> Kevin Rinek</a>, <a href="https://publications.waset.org/abstracts/search?q=Zach%20Barcroft"> Zach Barcroft</a>, <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Berglind"> Jennifer Berglind</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diet influences the composition of the gut microbiota and host's health. Disruption of the balance among the microbiota, epithelial cells, and resident immune cells in the intestine is involved in the pathogenesis of inflammatory bowel disease (IBD). To study the role of gut microbiota in intestinal inflammation, the microbiome of control mice (C57BL6) given a gluten-containing standard diet versus C57BL6 mice given the gluten-free (GF) feed (n=10 in each group) was examined. All mice received the 3% DSS for 5 days. Throughout the study, feces were collected and processed for DNA extraction and MiSeq Illumina sequencing of V4 region of bacterial 16S rRNA gene. Alpha and beta diversities and compositional differences at phylum and genus levels were determined in intestinal microbiota. The mice receiving the GF diet showed a significantly increased abundance of Firmicutes and a decrease of Bacteroides and Lactobacillus at phylum level. Therefore, the gluten free diet led to reductions in beneficial gut bacteria populations. These findings indicate a role of wheat gluten in dysbiosis of the intestinal microbiota. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gluten" title="gluten">gluten</a>, <a href="https://publications.waset.org/abstracts/search?q=colitis" title=" colitis"> colitis</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiota" title=" microbiota"> microbiota</a>, <a href="https://publications.waset.org/abstracts/search?q=DSS" title=" DSS"> DSS</a>, <a href="https://publications.waset.org/abstracts/search?q=dextran%20sulphate%20sodium" title=" dextran sulphate sodium"> dextran sulphate sodium</a> </p> <a href="https://publications.waset.org/abstracts/92869/dietary-gluten-and-the-balance-of-gut-microbiota-in-the-dextran-sulphate-sodium-induced-colitis-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92869.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">212</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">47</span> Hate Speech in Selected Nigerian Newspapers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laurel%20Chikwado%20Madumere">Laurel Chikwado Madumere</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20O.%20Ugorji"> Kevin O.

Therefore the aim of this paper is to investigate, using select daily newspapers in Nigeria, the extent and complexity of those likely hate speeches that emanate from the pluralism in Nigeria and to set in to relief, the discrepancies and contrariety in the interpretation of those hate words. To achieve the above, the paper shall be qualitative in orientation as it shall be using the Speech Act Theory of J. L. Austin and J. R. Searle to interpret and evaluate the hate speeches in the select Nigerian daily newspapers. Also this paper shall help to elucidate the conditions that generate hate, and inform the government and NGOs how best to approach those conditions and put an end to the possible violence and extremism that emanate from extreme cases of hate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extremism" title="extremism">extremism</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=hate%20speech" title=" hate speech"> hate speech</a>, <a href="https://publications.waset.org/abstracts/search?q=pluralism" title=" pluralism"> pluralism</a>, <a href="https://publications.waset.org/abstracts/search?q=prejudice" title=" prejudice"> prejudice</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20act%20theory" title=" speech act theory"> speech act theory</a> </p> <a href="https://publications.waset.org/abstracts/124330/hate-speech-in-selected-nigerian-newspapers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124330.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">146</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">46</span> Right to Return and Narrative in Refugee Camps: Case Study in Palestinian Displacement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naomi%20I.%20Austin">Naomi I.

The right to return has been disputed by the Israeli government and upheld as an individual by prominent Palestinian activists. Those who contest the Palestinian right to return argue that it would effectively end the state of Israel. After the conquest of Lebanon, the concept of a two-state solution has been effectively shut down. This research paper will seek to utilize interviews from NGO actors and those displaced to be gathered from fieldwork conducted in refugee camps and bases of international actors, exploring durable and multilateral solutions for not only the refugee crisis but the forced displacement of Palestinians that go beyond state actors and government entities. The research will center on the perspective of those displaced to generate a plausible solution to mitigate negative effects on displaced persons. This paper will seek to address whether the right to return is plausible with the expansion of Israeli territorial conquest and the impact of the Israeli expansion on migrations within the Mediterranean region and the EU, especially with policies of integration into the host community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=durable%20solutions" title="durable solutions">durable solutions</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20displacement" title=" forced displacement"> forced displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=protracted%20conflict" title=" protracted conflict"> protracted conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=refugee%20studies" title=" refugee studies"> refugee studies</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20building" title=" narrative building"> narrative building</a>, <a href="https://publications.waset.org/abstracts/search?q=memory" title=" memory"> memory</a>, <a href="https://publications.waset.org/abstracts/search?q=right%20to%20return" title=" right to return"> right to return</a> </p> <a href="https://publications.waset.org/abstracts/192644/right-to-return-and-narrative-in-refugee-camps-case-study-in-palestinian-displacement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192644.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">14</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">45</span> An Intelligence-Led Methodologly for Detecting Dark Actors in Human Trafficking Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrew%20D.%20Henshaw">Andrew D.

Austin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Human trafficking is an increasingly serious transnational criminal enterprise and social security issue. Despite ongoing efforts to mitigate the phenomenon and a significant expansion of security scrutiny over past decades, it is not receding. This is true for many nations in Southeast Asia, widely recognized as the global hub for trafficked persons, including men, women, and children. Clearly, human trafficking is difficult to address because there are numerous drivers, causes, and motivators for it to persist, such as non-military and non-traditional security challenges, i.e., climate change, global warming displacement, and natural disasters. These make displaced persons and refugees particularly vulnerable. The issue is so large conservative estimates put a dollar value at around $150 billion-plus per year (Niethammer, 2020) spanning sexual slavery and exploitation, forced labor, construction, mining and in conflict roles, and forced marriages of girls and women. Coupled with corruption throughout military, police, and civil authorities around the world, and the active hands of powerful transnational criminal organizations, it is likely that such figures are grossly underestimated as human trafficking is misreported, under-detected, and deliberately obfuscated to protect those profiting from it. For example, the 2022 UN report on human trafficking shows a 56% reduction in convictions in that year alone (UNODC, 2022). Our Approach: To better understand this, our research utilizes a bespoke methodology. Applying a JAM (Juxtaposition Assessment Matrix), which we previously developed to detect flows of dark money around the globe (Henshaw, A & Austin, J, 2021), we now focus on the human trafficking paradigm. Indeed, utilizing a JAM methodology has identified key indicators of human trafficking not previously explored in depth. Being a set of structured analytical techniques that provide panoramic interpretations of the subject matter, this iteration of the JAM further incorporates behavioral and driver indicators, including the employment of Open-Source Artificial Intelligence (OS-AI) across multiple collection points. The extracted behavioral data was then applied to identify non-traditional indicators as they contribute to human trafficking. Furthermore, as the JAM OS-AI analyses data from the inverted position, i.e., the viewpoint of the traffickers, it examines the behavioral and physical traits required to succeed. This transposed examination of the requirements of success delivers potential leverage points for exploitation in the fight against human trafficking in a new and novel way. Findings: Our approach identified new innovative datasets that have previously been overlooked or, at best, undervalued. For example, the JAM OS-AI approach identified critical 'dark agent' lynchpins within human trafficking that are difficult to detect and harder to connect to actors and agents within a network. Our preliminary data suggests this is in part due to the fact that ‘dark agents’ in extant research have been difficult to detect and potentially much harder to directly connect to the actors and organizations in human trafficking networks. Our research demonstrates that using new investigative techniques such as OS-AI-aided JAM introduces a powerful toolset to increase understanding of human trafficking and transnational crime and illuminate networks that, to date, avoid global law enforcement scrutiny. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20trafficking" title="human trafficking">human trafficking</a>, <a href="https://publications.waset.org/abstracts/search?q=open-source%20intelligence" title=" open-source intelligence"> open-source intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=transnational%20crime" title=" transnational crime"> transnational crime</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20security" title=" human security"> human security</a>, <a href="https://publications.waset.org/abstracts/search?q=international%20human%20rights" title=" international human rights"> international human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligence%20analysis" title=" intelligence analysis"> intelligence analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=JAM%20OS-AI" title=" JAM OS-AI"> JAM OS-AI</a>, <a href="https://publications.waset.org/abstracts/search?q=Dark%20Money" title=" Dark Money"> Dark Money</a> </p> <a href="https://publications.waset.org/abstracts/162450/an-intelligence-led-methodologly-for-detecting-dark-actors-in-human-trafficking-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162450.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">90</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> Numerical Investigation of the Effect of Blast Pressure on Discrete Model in Shock Tube</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aldin%20Justin%20Sundararaj">Aldin Justin Sundararaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Austin%20Lord%20Tennyson"> Austin Lord Tennyson</a>, <a href="https://publications.waset.org/abstracts/search?q=Divya%20Jose"> Divya Jose</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20N.%20Subash"> A.

An explosion yielding a blast wave has the potential to cause severe damage to buildings and its personnel. In order to understand the physics of effects of blast pressure on buildings, studies in the shock tube on generic configurations are carried out at various pressures on discrete models. The strength of shock wave is systematically varied by using different driver gases and diaphragm thickness. The basic material of the diaphragm is Aluminum. To simulate the effect of shock waves on discrete models a shock tube was used. Generic models selected for this study are suitably scaled cylinder, cone and cubical blocks. The experiments were carried out with 2mm diaphragm with burst pressure ranging from 28 to 31 bar. Numerical analysis was carried out over these discrete models. A 3D model of shock-tube with different discrete models inside the tube was used for CFD computation. It was found that cone has dissipated most of the shock pressure compared to cylinder and cubical block. The robustness and the accuracy of the numerical model were validation with the analytical and experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shock%20wave" title="shock wave">shock wave</a>, <a href="https://publications.waset.org/abstracts/search?q=blast%20wave" title=" blast wave"> blast wave</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20models" title=" discrete models"> discrete models</a>, <a href="https://publications.waset.org/abstracts/search?q=shock%20tube" title=" shock tube"> shock tube</a> </p> <a href="https://publications.waset.org/abstracts/58116/numerical-investigation-of-the-effect-of-blast-pressure-on-discrete-model-in-shock-tube" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58116.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">330</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">43</span> Molecular Modeling of 17-Picolyl and 17-Picolinylidene Androstane Derivatives with Anticancer Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanja%20Podunavac-Kuzmanovi%C4%87">Sanja Podunavac-Kuzmanović</a>, <a href="https://publications.waset.org/abstracts/search?q=Strahinja%20Kova%C4%8Devi%C4%87"> Strahinja Kovačević</a>, <a href="https://publications.waset.org/abstracts/search?q=Lidija%20Jevri%C4%87"> Lidija Jevrić</a>, <a href="https://publications.waset.org/abstracts/search?q=Evgenija%20Djurendi%C4%87"> Evgenija Djurendić</a>, <a href="https://publications.waset.org/abstracts/search?q=Jovana%20Ajdukovi%C4%87"> Jovana Ajduković</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the molecular modeling of a series of 24 17-picolyl and 17-picolinylidene androstane derivatives whit significant anticancer activity was carried out.

The obtained 3D structures were subjected to energy minimization using molecular mechanics force field method (MM2). The cutoff for structure optimization was set at a gradient of 0.1 kcal/Åmol. Full geometry optimization was done by the Austin Model 1 (AM1) until the root mean square (RMS) gradient reached a value smaller than 0.0001 kcal/Åmol using Molecular Orbital Package (MOPAC) program. The obtained physicochemical, lipophilicity and topological descriptors were used for analysis of molecular similarities and dissimilarities applying suitable chemometric methods (principal component analysis and cluster analysis).

However, there has been no report on this gene in the Thai population. Objective: Our aim in this study is to explore and compare the frequency of HLA-C allele that is associated with severe COVID-19 symptoms in Thais and other populations. Method: 200 general Thai population were enrolled in this study. The genotyping of HLA -C alleles were determined by the polymerase chain reaction with sequence-specific oligonucleotide probes (PCR-SSOP) and Luminex®IS 100 system (Luminex Corporation, Austin, Texas, USA). Results: We found that the frequency of alleles HLA-C* 01:02 (16.00%), HLA-C* 08:01(10.50%), HLA-C* 03:04 (10.25%),HLA-C* 07:02 (10.00%), HLA-C* 03:02 (9.25%), HLA-C* 07:01 (6.75%), HLA-C* 04:01 (5.00%), HLA-C* 06:02 (4.00%), HLA-C* 04:03 (4.00%), and HLA-C* 07:04 (3.75%) were more common in the Thai population. HLA-C* 01:02 (16.00%) allele was the highest frequency in the North, Center, and North East groups in Thailand, but there was the South region that was not significantly different when compared with the other groups of the region. Additionally, HLA-C∗14:02 allele was similarly distributed in Thais (3.00%), African Americans (1.98%), Caucasians (2.08%), Hispanics (1.71%), North American Natives (1.34%) and Asians (5.01%) by p-value = 0.6506, 0.6506, 0.6506, 0.6135 and 0.7182, respectively. Conclusion: Genetic variation database is important to identify HLA can be a risk factor for severe COVID-19 in many populations. In this study, we will support the research of the HLA markers for screening severe COVID-19 in many populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HLA-C%20%2A%2014%3A02" title="HLA-C * 14:02">HLA-C * 14:02</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=allele%20frequency" title=" allele frequency"> allele frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=Thailand" title=" Thailand"> Thailand</a> </p> <a href="https://publications.waset.org/abstracts/155165/the-distribution-of-hla-c-1402-allele-in-thai-population-to-see-risk-factors-for-severe-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155165.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">41</span> Reducing Crash Risk at Intersections with Safety Improvements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Upal%20Barua">Upal Barua</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crash risk at intersections is a critical safety issue. This paper examines the effectiveness of removing an existing off-set at an intersection by realignment, in reducing crashes. Empirical Bayes method was applied to conduct a before-and-after study to assess the effect of this safety improvement. The Transportation Safety Improvement Program in Austin Transportation Department completed several safety improvement projects at high crash intersections with a view to reducing crashes. One of the common safety improvement techniques applied was the realignment of intersection approaches removing an existing off-set. This paper illustrates how this safety improvement technique is applied at a high crash intersection from inception to completion. This paper also highlights the significant crash reductions achieved from this safety improvement technique applying Empirical Bayes method in a before-and-after study. The result showed that realignment of intersection approaches removing an existing off-set can reduce crashes by 53%. This paper also features the state of the art techniques applied in planning, engineering, designing and construction of this safety improvement, key factors driving the success, and lessons learned in the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crash%20risk" title="crash risk">crash risk</a>, <a href="https://publications.waset.org/abstracts/search?q=intersection" title=" intersection"> intersection</a>, <a href="https://publications.waset.org/abstracts/search?q=off-set" title=" off-set"> off-set</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20improvement%20technique" title=" safety improvement technique"> safety improvement technique</a>, <a href="https://publications.waset.org/abstracts/search?q=before-and-after%20study" title=" before-and-after study"> before-and-after study</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20Bayes%20method" title=" empirical Bayes method"> empirical Bayes method</a> </p> <a href="https://publications.waset.org/abstracts/94343/reducing-crash-risk-at-intersections-with-safety-improvements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94343.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">245</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">40</span> Spatiotemporal Analysis of Land Surface Temperature and Urban Heat Island Evaluation of Four Metropolitan Areas of Texas, USA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chunhong%20Zhao">Chunhong Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Remotely sensed land surface temperature (LST) is vital to understand the land-atmosphere energy balance, hydrological cycle, and thus is widely used to describe the urban heat island (UHI) phenomenon. However, due to technical constraints, satellite thermal sensors are unable to provide LST measurement with both high spatial and high temporal resolution. Despite different downscaling techniques and algorithms to generate high spatiotemporal resolution LST. Four major metropolitan areas in Texas, USA: Dallas-Fort Worth, Houston, San Antonio, and Austin all demonstrate UHI effects. Different cities are expected to have varying SUHI effect during the urban development trajectory. With the help of the Landsat, ASTER, and MODIS archives, this study focuses on the spatial patterns of UHIs and the seasonal and annual variation of these metropolitan areas. With Gaussian model, and Local Indicators of Spatial Autocorrelations (LISA), as well as data fusion methods, this study identifies the hotspots and the trajectory of the UHI phenomenon of the four cities. By making comparison analysis, the result can help to alleviate the advent effect of UHI and formulate rational urban planning in the long run. <p class="card-text"><strong>Keywords:</strong> <a
