The Bending rigidity of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) membrane was measured at 28 °C by employing Vesicle Fluctuation Analysis technique. The concentration and chain length (n) of alcohol in the buffer solution were varied from 0 to 1.5 M and from 2 to 8 respectively. We observed a non-linear reduction in the bending rigidity from ~17×10⁻²⁰ J to ~10×10⁻²⁰ J, for all chain lengths of alcohols used in our experiment. We observed approximately three orders of the concentration difference between ethanol and octanol, to show the similar reduction in the bending values. We attribute this phenomenon to thinning of the bilayer due to the adsorption of alcohols at the bilayer-water interface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alcohols" title="alcohols">alcohols</a>, <a href="https://publications.waset.org/abstracts/search?q=bending%20rigidity" title=" bending rigidity"> bending rigidity</a>, <a href="https://publications.waset.org/abstracts/search?q=DMPC" title=" DMPC"> DMPC</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20bilayers" title=" lipid bilayers"> lipid bilayers</a> </p> <a href="https://publications.waset.org/abstracts/100295/effect-of-short-chain-alcohols-on-bending-rigidity-of-lipid-bilayer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100295.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">19</span> Rotational Energy Recovery System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vijayendra%20Anil%20Menon">Vijayendra Anil Menon</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashwath%20Narayan%20Murali"> Ashwath Narayan Murali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present day vehicles do not reuse the energy expelled in running the vehicle.

The field was found to be economically challenging even during high oil prices and the project was put on hold. Shell started development study with the aim to significantly reduce cost through competitively scoping and revive stranded projects. The proposed strategy to achieve this involved Improve Per platform recovery and Reduction in CAPEX. Methodology: Based on various Benchmarking Tool such as Woodmac for similar projects in the region and economic affordability, a challenging target of 50% reduction in unit development cost (UDC) was set for the project. Technical scope was defined to the minimum as to be a wellhead platform with minimum functionality to ensure production. The evaluation of key project decisions like Well location and number, well design, Artificial lift methods and wellhead platform type under different development concept was carried out through integrated multi-discipline approach. Key elements influencing per platform recovery were Wellhead Platform (WHP) location, Well count, well reach and well productivity. Major Findings: Reservoir being shallow posed challenges in well design (dog-leg severity, casing size and the achievable step-out), choice of artificial lift and sand-control method. Integrated approach amongst relevant disciplines with challenging mind-set enabled to achieve optimized set of development decisions. This led to significant improvement in per platform recovery. It was concluded that platform recovery largely depended on the reach of the well. Choice of slim well design enabled designing of high inclination and better productivity wells. However, there is trade-off between high inclination Gas Lift (GL) wells and low inclination wells in terms of long term value, operational complexity, well reach, recovery and uptime. Well design element like casing size, well completion, artificial lift and sand control were added successively over the minimum technical scope design leading to a value and risk staircase. Logical combinations of options (slim well, GL) were competitively screened to achieve 25% reduction in well cost. Facility cost reduction was achieved through sourcing standardized Low Cost Facilities platform in combination with portfolio execution to maximizing execution efficiency; this approach is expected to reduce facilities cost by ~23% with respect to the development costs. Further cost reductions were achieved by maximizing use of existing facilities nearby; changing reliance on existing water injection wells and utilizing existing water injector (W.I.) platform for new injectors. Conclusion: The study provides a spectrum of technically feasible options. It also made clear that different drivers lead to different development concepts and the cost value trade off staircase made this very visible. Scoping of the project through competitive way has proven to be valuable for decision makers by creating a transparent view of value and associated risks/uncertainty/trade-offs for difficult choices: elements of the projects can be competitive, whilst other parts will struggle, even though contributing to significant volumes. Reduction in UDC through proper scoping of present projects and its benchmarking paves as a learning for the development of marginal fields across the world, especially in this low oil price scenario. This way of developing a field has on average a reduction of 40% of cost for the Shell projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benchmarking" title="benchmarking">benchmarking</a>, <a href="https://publications.waset.org/abstracts/search?q=full%20field%20development" title=" full field development"> full field development</a>, <a href="https://publications.waset.org/abstracts/search?q=CAPEX" title=" CAPEX"> CAPEX</a>, <a href="https://publications.waset.org/abstracts/search?q=feasibility" title=" feasibility"> feasibility</a> </p> <a href="https://publications.waset.org/abstracts/77000/successful-optimization-of-a-shallow-marginal-offshore-field-and-its-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77000.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">158</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> Copper Oxide Doped Carbon Catalyst for Anodic Half-Cell of Vanadium Redox Flow Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Irshad%20U.%20Khan">Irshad U.

The mathematical modeling of the abstraction encapsulates the current tree position, which can be used to navigate and modify the tree. The encapsulation of the tree position in the data abstraction specification avoids the use of explicit references and aliasing, thereby simplifying verification of (imperative) client code that uses the data abstraction. To ease the tasks of such specification and verification, a general tree theory, rich with mathematical notations and results, has been developed. The paper contains an example to illustrate automated verification ramifications. With sufficient tree theory development, automated proving seems plausible even in the absence of a special-purpose tree solver. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automation" title="automation">automation</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20abstraction" title=" data abstraction"> data abstraction</a>, <a href="https://publications.waset.org/abstracts/search?q=maps" title=" maps"> maps</a>, <a href="https://publications.waset.org/abstracts/search?q=specification" title=" specification"> specification</a>, <a href="https://publications.waset.org/abstracts/search?q=tree" title=" tree"> tree</a>, <a href="https://publications.waset.org/abstracts/search?q=verification" title=" verification"> verification</a> </p> <a href="https://publications.waset.org/abstracts/131080/an-encapsulation-of-a-navigable-tree-position-theory-specification-and-verification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131080.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">15</span> Analysis of Q-Learning on Artificial Neural Networks for Robot Control Using Live Video Feed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihal%20Murali">Nihal Murali</a>, <a href="https://publications.waset.org/abstracts/search?q=Kunal%20Gupta"> Kunal Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Surekha%20Bhanot"> Surekha Bhanot</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Training of artificial neural networks (ANNs) using reinforcement learning (RL) techniques is being widely discussed in the robot learning literature. The high model complexity of ANNs along with the model-free nature of RL algorithms provides a desirable combination for many robotics applications. There is a huge need for algorithms that generalize using raw sensory inputs, such as vision, without any hand-engineered features or domain heuristics. In this paper, the standard control problem of line following robot was used as a test-bed, and an ANN controller for the robot was trained on images from a live video feed using Q-learning. A virtual agent was first trained in simulation environment and then deployed onto a robot’s hardware. The robot successfully learns to traverse a wide range of curves and displays excellent generalization ability. Qualitative analysis of the evolution of policies, performance and weights of the network provide insights into the nature and convergence of the learning algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20networks" title="artificial neural networks">artificial neural networks</a>, <a href="https://publications.waset.org/abstracts/search?q=q-learning" title=" q-learning"> q-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=robot%20learning" title=" robot learning"> robot learning</a> </p> <a href="https://publications.waset.org/abstracts/70136/analysis-of-q-learning-on-artificial-neural-networks-for-robot-control-using-live-video-feed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70136.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">372</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">14</span> Design of an Electric Vehicle Model with a Dynamo Drive Setup Using Model-Based Development (MBD) (EV Using MBD)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gondu%20Vykunta%20Rao">Gondu Vykunta Rao</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhuri%20Bayya"> Madhuri Bayya</a>, <a href="https://publications.waset.org/abstracts/search?q=Aruna%20Bharathi%20M."> Aruna Bharathi M.</a>, <a href="https://publications.waset.org/abstracts/search?q=Paramesw%20Chidamparam"> Paramesw Chidamparam</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Murali"> B.

As for understanding and visualization, the companies are turning toward the virtual vehicle to test their design in software which is known as a simulation in the loop (SIL). In this project, in addition to the electric vehicle (EV) technology, we are adding a dynamo with the vehicle for regenerative braking. Traditionally the principle of dynamos is used in lighting the purpose of the bicycle.

Nowadays, people are worrying to choose data accessing and extraction tools at the time of buying and selling their products. In addition, worry about various quality factors such as price, durability, color, size, and availability of the product. The main purpose of the research study is to find solutions to these unsolved existing problems. The proposed algorithm is a Multidirectional Rank Prediction (MDRP) decision making algorithm in order to take an effective strategic decision at all the levels of data extraction, uses a real time textile dataset and analyzes the results. Finally, the results are obtained and compared with the existing measurement methods such as PCC, SLCF, and VSS. The result accuracy is higher than the existing rank prediction methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Knowledge%20Discovery%20in%20Database%20%28KDD%29" title="Knowledge Discovery in Database (KDD)">Knowledge Discovery in Database (KDD)</a>, <a href="https://publications.waset.org/abstracts/search?q=Multidirectional%20Rank%20Prediction%20%28MDRP%29" title=" Multidirectional Rank Prediction (MDRP)"> Multidirectional Rank Prediction (MDRP)</a>, <a href="https://publications.waset.org/abstracts/search?q=Pearson%E2%80%99s%20Correlation%20Coefficient%20%28PCC%29" title=" Pearson’s Correlation Coefficient (PCC)"> Pearson’s Correlation Coefficient (PCC)</a>, <a href="https://publications.waset.org/abstracts/search?q=VSS%20%28Vector%20Space%20Similarity%29" title=" VSS (Vector Space Similarity)"> VSS (Vector Space Similarity)</a> </p> <a href="https://publications.waset.org/abstracts/3247/multidirectional-product-support-system-for-decision-making-in-textile-industry-using-collaborative-filtering-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3247.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">286</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">12</span> Disaster Management Using Wireless Sensor Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akila%20Murali">Akila Murali</a>, <a href="https://publications.waset.org/abstracts/search?q=Prithika%20Manivel"> Prithika Manivel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Disasters are defined as a serious disruption of the functioning of a community or a society, which involves widespread human, material, economic or environmental impacts. The number of people suffering food crisis as a result of natural disasters has tripled in the last thirty years. The economic losses due to natural disasters have shown an increase with a factor of eight over the past four decades, caused by the increased vulnerability of the global society, and also due to an increase in the number of weather-related disasters. Efficient disaster detection and alerting systems could reduce the loss of life and properties. In the event of a disaster, another important issue is a good search and rescue system with high levels of precision, timeliness and safety for both the victims and the rescuers. Wireless Sensor Networks technology has the capability of quick capturing, processing, and transmission of critical data in real-time with high resolution. This paper studies the capacity of sensors and a Wireless Sensor Network to collect, collate and analyze valuable and worthwhile data, in an ordered manner to help with disaster management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alerting%20systems" title="alerting systems">alerting systems</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster%20detection" title=" disaster detection"> disaster detection</a>, <a href="https://publications.waset.org/abstracts/search?q=Ad%20Hoc%20network" title=" Ad Hoc network"> Ad Hoc network</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN%20technology" title=" WSN technology "> WSN technology </a> </p> <a href="https://publications.waset.org/abstracts/36092/disaster-management-using-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36092.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">404</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">11</span> Indoor Visible Light Communication Channel Characterization for User Mobility: A Use-Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pooja%20Sanathkumar">Pooja Sanathkumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Srinidhi%20Murali"> Srinidhi Murali</a>, <a href="https://publications.waset.org/abstracts/search?q=Sethuraman%20TV"> Sethuraman TV</a>, <a href="https://publications.waset.org/abstracts/search?q=Saravanan%20M"> Saravanan M</a>, <a href="https://publications.waset.org/abstracts/search?q=Paventhan%20Arumugam"> Paventhan Arumugam</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashwin%20Ashok"> Ashwin Ashok</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The last decade has witnessed a significant interest in visible light communication (VLC) technology, as VLC can potentially achieve high data rate links and secure communication channels.

Recent studies shows that up regulation of mRNA cause serious diseases like Cancer. So designing effective siRNA with good knockdown effects play an important role in gene silencing. Various siRNA design tools had been developed earlier. In this work, we are trying to analyze the existing good scoring second generation siRNA predicting tools and to optimize the efficiency of siRNA prediction by designing a computational model using Artificial Neural Network and whole stacking energy (ΔG), which may help in gene silencing and drug design in cancer therapy. Our model is trained and tested against a large data set of siRNA sequences. Validation of our results is done by finding correlation coefficient of experimental versus observed inhibition efficacy of siRNA. We achieved a correlation coefficient of 0.727 in our previous computational model and we could improve the correlation coefficient up to 0.753 when the threshold of whole tacking energy is greater than or equal to -32.5 kcal/mol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20stranded%20RNA" title=" double stranded RNA"> double stranded RNA</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA%20interference" title=" RNA interference"> RNA interference</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20interfering%20RNA" title=" short interfering RNA"> short interfering RNA</a> </p> <a href="https://publications.waset.org/abstracts/16841/computational-model-for-predicting-effective-sirna-sequences-using-whole-stacking-energy-dg-for-gene-silencing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16841.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">526</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">9</span> Investigation of Chord Protocol in Peer to Peer Wireless Mesh Network with Mobility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Prasanna%20Murali%20Krishna">P.

Structured P2P approaches are widely used in adhoc networks due to its distributed and scalability features. Efficient mechanisms are required to handle the huge amount of data distributed to all peers. The intrinsic characteristics of P2P system makes for easier content distribution when compared to client-server architecture. All the nodes in a P2P network act as both client and server, thus, distributing data takes lesser time when compared to the client-server method. CHORD protocol is a resource routing based where nodes and data items are structured into a 1- dimensional ring. The structured lookup algorithm of Chord is advantageous for distributed P2P networking applications. Though, structured approach improves lookup performance in a high bandwidth wired network it could contribute to unnecessary overhead in overlay networks leading to degradation of network performance. In this paper, the performance of existing CHORD protocol on Wireless Mesh Network (WMN) when nodes are static and dynamic is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20mesh%20network%20%28WMN%29" title="wireless mesh network (WMN)">wireless mesh network (WMN)</a>, <a href="https://publications.waset.org/abstracts/search?q=structured%20P2P%0D%0Anetworks" title=" structured P2P networks"> structured P2P networks</a>, <a href="https://publications.waset.org/abstracts/search?q=peer%20to%20peer%20resource%20sharing" title=" peer to peer resource sharing"> peer to peer resource sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=CHORD%20Protocol" title=" CHORD Protocol"> CHORD Protocol</a>, <a href="https://publications.waset.org/abstracts/search?q=DHT" title=" DHT"> DHT</a> </p> <a href="https://publications.waset.org/abstracts/34950/investigation-of-chord-protocol-in-peer-to-peer-wireless-mesh-network-with-mobility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34950.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">480</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">8</span> Mathematical Model for Output Yield Obtained by Single Slope Solar Still</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20Nagaraju">V.

The mathematical model and results obtained with the experimental investigation are within 11% of deviation. The theoretical model to predict the yield obtained due to the capillary effect was proposed first. And then, to predict the total yield obtained, the thermal effect model was integrated with the capillary effect model. With the obtained results, it is understood that the yield obtained is more in the case of solar stills with sand-filled cylindrical pipes when compared to solar stills without sand-filled cylindrical pipes. And later model was used for predicting yield for 1 cm and 2 cm of water levels at the basin. And it is observed that the maximum yield was obtained for a 1 cm water level at the basin. It means solar still produces better yield with the lower depth of water level at the basin; this may be because of the availability of more space in the sand for evaporation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20still" title="solar still">solar still</a>, <a href="https://publications.waset.org/abstracts/search?q=cylindrical%20pipes" title=" cylindrical pipes"> cylindrical pipes</a>, <a href="https://publications.waset.org/abstracts/search?q=still%20efficiency" title=" still efficiency"> still efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20effect%20model" title=" capillary effect model"> capillary effect model</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20desalination" title=" solar desalination"> solar desalination</a> </p> <a href="https://publications.waset.org/abstracts/132116/mathematical-model-for-output-yield-obtained-by-single-slope-solar-still" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132116.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">119</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">7</span> Cultural Boundaries and Mental Health Stigma: A Systemic Review of Interventions to Reduce Opposition of Mental Health Services in Asian American Families</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanya%20L.%20Patimeteeporn">Tanya L.

These factors arise from a combination of cultural perceptions of mental illness, and methods of treating them without the use of a mental health professional. Due to the increased awareness of Asian Americans’ stigmatization to mental health, there has been an effort to create culturally competent interventions for Asian American families that would reduce opposition to mental health services. Assessment of the effectiveness of these interventions reveals practices that integrate traditional healing methods with psychoeducation are more likely to promote receptiveness of mental health services by Asian American families. The documentary in this review, demonstrates these traditional healing methods from various ethnic enclaves in Los Angeles. In addition, mental health professionals who provide these interventions to Asian American families need to consider culture-bound syndromes and the various Asian health philosophies and belief systems in order to provide a culturally sensitive holistic treatment for their clients. However, because the literature on these interventions is limited, there is a need for a larger body of evidence to accurately assess the effectiveness of these culturally competent psychoeducation interventions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asian%20American" title="Asian American">Asian American</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20boundaries" title=" cultural boundaries"> cultural boundaries</a>, <a href="https://publications.waset.org/abstracts/search?q=intervention" title=" intervention"> intervention</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health%20stigma" title=" mental health stigma"> mental health stigma</a>, <a href="https://publications.waset.org/abstracts/search?q=psychoeducation" title=" psychoeducation"> psychoeducation</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20healing" title=" traditional healing"> traditional healing</a> </p> <a href="https://publications.waset.org/abstracts/58515/cultural-boundaries-and-mental-health-stigma-a-systemic-review-of-interventions-to-reduce-opposition-of-mental-health-services-in-asian-american-families" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58515.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">547</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">6</span> Mechanistic Understanding of the Difference in two Strains Cholerae Causing Pathogens and Predicting Therapeutic Strategies for Cholera Patients Affected with new Strain Vibrio Cholerae El.tor.

Different strains of VC exhibit variable responses subject to different extracellular medium (Nag et al, Infect Immun, 2018). In this study, we present a new approach to model the variable VC responses in mono- and co-cultures, subject to continuously changing growth medium, which is otherwise difficult via simple FBA model. Nine VC strain and seven E. coli (EC) models were assembled and considered. A continuously changing medium is modelled using a new iterative-based controlled medium technique (ITC). The medium is appropriately prefixed with the VC model secretome. As the flux through the bacteria biomass increases secretes certain by-products. These products shall add-on to the medium, either deviating the nutrient potential or block certain metabolic components of the model, effectively forming a controlled feed-back loop. Different VC models were setup as monoculture of VC in glucose enriched medium, and in co-culture with VC strains and EC. Constrained to glucose enriched medium, (i) VC_Classical model resulted in higher flux through acidic secretome suggesting a pH change of the medium, leading to lowering of its biomass. This is in consonance with the literature reports. (ii) When compared for neutral secretome, flux through acetoin exchange was higher in VC_El tor than the classical models, suggesting El tor requires an acidic partner to lower its biomass. (iii) Seven of nine VC models predicted 3-methyl-2-Oxovaleric acid, mysirtic acid, folic acid, and acetate significantly affect corresponding biomass reactions. (iv) V. parhemolyticus and vulnificus were found to be phenotypically similar to VC Classical strain, across the nine VC strains. The work addresses the advantage of the ITC over regular flux balance analysis for modelling varying growth medium. Future expansion to co-cultures, potentiates the identification of novel interacting partners as effective cholera therapeutics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cholera" title="cholera">cholera</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrio%20cholera%20El.%20tor" title=" vibrio cholera El. tor"> vibrio cholera El. tor</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrio%20cholera%20classical" title=" vibrio cholera classical"> vibrio cholera classical</a>, <a href="https://publications.waset.org/abstracts/search?q=acetate" title=" acetate"> acetate</a> </p> <a href="https://publications.waset.org/abstracts/144406/mechanistic-understanding-of-the-difference-in-two-strains-cholerae-causing-pathogens-and-predicting-therapeutic-strategies-for-cholera-patients-affected-with-new-strain-vibrio-cholerae-eltor-using-constrain-based-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144406.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">162</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">5</span> Pharmacogenetics of Uridine Diphosphate Glucuronosyltransferase (UGT1A9) Genetic Polymorphism on Sodium Valproate Pharmacokinetics in Epilepsy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murali%20Munisamy">Murali Munisamy</a>, <a href="https://publications.waset.org/abstracts/search?q=Gauthaman%20Karunakaran"> Gauthaman Karunakaran</a>, <a href="https://publications.waset.org/abstracts/search?q=Mubarak%20Al-Gahtany"> Mubarak Al-Gahtany</a>, <a href="https://publications.waset.org/abstracts/search?q=Vivekanandhan%20Subbiah"> Vivekanandhan Subbiah</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Manjari%20%20Tripati"> M.

It shows high inter-individual variability in pharmacokinetics and pharmacodynamics and has a narrow therapeutic range. We evaluated the effects of polymorphic uridine diphosphate glucuronosyltransferase (UGT1A9) metabolizing enzyme on the pharmacokinetics of sodium valproate in the patients with epilepsy who showed toxicity to therapy. Methods: Genotype analysis of the patients was made with polymerase chain–restriction fragment length polymorphism (RFLP) with sequencing. Plasma drug concentrations were measured with reversed phase high-performance liquid chromatography (HPLC) and concentration–time data were analyzed by using a non-compartmental approach. Results: The results of this study suggested a significant genotypic as well as allelic association with valproic acid toxicity for UGT1A9 polymorphic enzymes. The elimination half-life (t 1/2=40.2 h) of valproic acid was longer and the clearance rate (CL=937 ml/h) was lower in the poor metabolizers group of UGT1A9 polymorphism who showed toxicity than in the intermediate metabolizers group (t1/2=35.5 h, CL=1042 ml/h) or the extensive metabolizers group (t1/2=26. h, CL=1,302 ml/h). Conclusion: Our findings suggest that the UGT1A9 genetic polymorphism plays a significant role in the steady state concentration of sodium valproate, and it thereby has an impact on the toxicity of the sodium valproate used in the patients with epilepsy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UGT1A9" title="UGT1A9">UGT1A9</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20valporate" title=" sodium valporate"> sodium valporate</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacogenetics" title=" pharmacogenetics"> pharmacogenetics</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism "> polymorphism </a> </p> <a href="https://publications.waset.org/abstracts/17536/pharmacogenetics-of-uridine-diphosphate-glucuronosyltransferase-ugt1a9-genetic-polymorphism-on-sodium-valproate-pharmacokinetics-in-epilepsy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17536.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">425</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">4</span> Behavioural Studies on Multidirectional Reinforced 4-D Orthogonal Composites on Various Preform Configurations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sriram%20Venkatesh">Sriram Venkatesh</a>, <a href="https://publications.waset.org/abstracts/search?q=V.%20Murali%20Mohan"> V.

This technology provides the means to produce tailored composites with desired properties. Due to the high level of fibre integrity with through thickness reinforcement those composites are expected to exhibit superior load bearing characteristics with capability to carry load even after noticeable and apparent fracture. However a survey of published literature indicates inadequacy in the design and test data base for the complete characterization of the multidirectional composites. In this paper the research objective is focused on the development and testing of 4-D orthogonal composites with different preform configurations and resin systems. A preform is the skeleton 4D reinforced composite other than the matrix. In 4-D preforms fibre bundles are oriented in three directions at 1200 with respect to each other and they are on orthogonal plane with the fibre in 4th direction. This paper addresses the various types of 4-D composite manufacturing processes and the mechanical test methods followed for the material characterization. A composite analysis is also made, experiments on course and fine woven preforms are conducted and the findings of test results are discussed in this paper. The interpretations of the test results reveal several useful and interesting features. This should pave the way for more widespread use of the perform configurations for allied applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-directionally%20reinforced%20composites" title="multi-directionally reinforced composites">multi-directionally reinforced composites</a>, <a href="https://publications.waset.org/abstracts/search?q=4-D%20orthogonal%20preform" title=" 4-D orthogonal preform"> 4-D orthogonal preform</a>, <a href="https://publications.waset.org/abstracts/search?q=course%20weave" title=" course weave"> course weave</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20weave" title=" fine weave"> fine weave</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20bundle%20spools" title=" fibre bundle spools"> fibre bundle spools</a>, <a href="https://publications.waset.org/abstracts/search?q=unit%20cell" title=" unit cell"> unit cell</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20architecture" title=" fibre architecture"> fibre architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20volume%20fraction" title=" fibre volume fraction"> fibre volume fraction</a>, <a href="https://publications.waset.org/abstracts/search?q=fibre%20distribution" title=" fibre distribution"> fibre distribution</a> </p> <a href="https://publications.waset.org/abstracts/5808/behavioural-studies-on-multidirectional-reinforced-4-d-orthogonal-composites-on-various-preform-configurations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5808.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">232</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">3</span> Parametric Appraisal of Robotic Arc Welding of Mild Steel Material by Principal Component Analysis-Fuzzy with Taguchi Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amruta%20Rout">Amruta Rout</a>, <a href="https://publications.waset.org/abstracts/search?q=Golak%20Bihari%20Mahanta"> Golak Bihari Mahanta</a>, <a href="https://publications.waset.org/abstracts/search?q=Gunji%20Bala%20Murali"> Gunji Bala Murali</a>, <a href="https://publications.waset.org/abstracts/search?q=Bibhuti%20Bhusan%20Biswal"> Bibhuti Bhusan Biswal</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20B.%20V.%20L.%20Deepak"> B.

The weld joint parameter and weld process parameter modeling is one of the most crucial aspects of robotic welding. As weld process parameters affect the weld joint parameters differently, a multi-objective optimization technique has to be utilized to obtain optimal setting of weld process parameter. In this paper, a hybrid optimization technique, i.e., Principal Component Analysis (PCA) combined with fuzzy logic has been proposed to get optimal setting of weld process parameters like wire feed rate, welding current. Gas flow rate, welding speed and nozzle tip to plate distance. The weld joint parameters considered for optimization are the depth of penetration, yield strength, and ultimate strength. PCA is a very efficient multi-objective technique for converting the correlated and dependent parameters into uncorrelated and independent variables like the weld joint parameters. Also in this approach, no need for checking the correlation among responses as no individual weight has been assigned to responses. Fuzzy Inference Engine can efficiently consider these aspects into an internal hierarchy of it thereby overcoming various limitations of existing optimization approaches. At last Taguchi method is used to get the optimal setting of weld process parameters. Therefore, it has been concluded the hybrid technique has its own advantages which can be used for quality improvement in industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=robotic%20arc%20welding" title="robotic arc welding">robotic arc welding</a>, <a href="https://publications.waset.org/abstracts/search?q=weld%20process%20parameters" title=" weld process parameters"> weld process parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=weld%20joint%20parameters" title=" weld joint parameters"> weld joint parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a> </p> <a href="https://publications.waset.org/abstracts/87646/parametric-appraisal-of-robotic-arc-welding-of-mild-steel-material-by-principal-component-analysis-fuzzy-with-taguchi-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87646.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">179</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">2</span> Identification of Analogues to EGCG for the Inhibition of HPV E7: A Fundamental Insights through Structural Dynamics Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Murali%20Aarthy">Murali Aarthy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjeev%20Kumar%20Singh"> Sanjeev Kumar Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High risk human papillomaviruses are highly associated with the carcinoma of the cervix and the other genital tumors. Cervical cancer develops through the multistep process in which increasingly severe premalignant dysplastic lesions called cervical intraepithelial neoplastic progress to invasive cancer. The oncoprotein E7 of human papillomavirus expressed in the lower epithelial layers drives the cells into S-phase creating an environment conducive for viral genome replication and cell proliferation. The replication of the virus occurs in the terminally differentiating epithelium and requires the activation of cellular DNA replication proteins. To date, no suitable drug molecule is available to treat HPV infection whereas identification of potential drug targets and development of novel anti-HPV chemotherapies with unique mode of actions are expected. Hence, our present study aimed to identify the potential inhibitors analogous to EGCG, a green tea molecule which is considered to be safe to use for mammalian systems. A 3D similarity search on the natural small molecule library from natural product database using EGCG identified 11 potential hits based on their similarity score. The structure based docking strategies were implemented in the potential hits and the key interacting residues of protein with compounds were identified through simulation studies and binding free energy calculations. The conformational changes between the apoprotein and the complex were analyzed with the simulation and the results demonstrated that the dynamical and structural effects observed in the protein were induced by the compounds and indicated the dominance to the oncoprotein. Overall, our study provides the basis for the structural insights of the identified potential hits and EGCG and hence, the analogous compounds identified can be potent inhibitors against the HPV 16 E7 oncoprotein. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EGCG" title="EGCG">EGCG</a>, <a href="https://publications.waset.org/abstracts/search?q=oncoprotein" title=" oncoprotein"> oncoprotein</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=analogues" title=" analogues"> analogues</a> </p> <a href="https://publications.waset.org/abstracts/103219/identification-of-analogues-to-egcg-for-the-inhibition-of-hpv-e7-a-fundamental-insights-through-structural-dynamics-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103219.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">127</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">1</span> Mental Health on Three Continents: A Comparison of Mental Health Disorders in the Usa, India and Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Henry%20Venter">Henry Venter</a>, <a href="https://publications.waset.org/abstracts/search?q=Murali%20Thyloth"> Murali Thyloth</a>, <a href="https://publications.waset.org/abstracts/search?q=Alceu%20Casseb"> Alceu Casseb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Historically, mental and substance use disorders were not a global health priority. Since the 1993 World Development Report, the importance of the contribution of mental health and substance abuse on the relative global burden associated with disease morbidity has been recognized with 300 million people worldwide suffering from depression alone. This led to an international effort to improve the mental health of populations around the world. Despite these efforts some countries remain at the top of the list of countries with the highest rate of mental illness. Important research questions were asked: Would there be commonalities regarding mental health between these countries; would there be common factors leading to the high prevalence of mental illness; and how prepared are these countries with mental health delivery? Findings from this research can aid organizations and institutions preparing mental health service providers to focus training and preparation to address specific needs revealed by the study. Methods: Researchers decided to compare three distinctly different countries at the top of the list of countries with the highest rate of mental illness, the USA, India and Brazil, situated on three different continents with different economies and lifestyles. Data were collected using archival research methodology, reviewing records and findings of international and national health and mental health studies to subtract and compare data and findings. Results: The findings indicated that India is the most depressed country in the world, followed by the USA (and China) with Brazil in Latin America with the greatest number of depressed individuals. By 2020 roughly 20% of India, acountry of over one billion citizens, will suffer from some form of mental illnees, yet there are less than 4,000 experts available. In the USA 164.8 million people were substance abusers and an estimate of 47.6 million adults, 18 or older, had any mental illness in 2018. That means that about one in five adults in the USA experiences some form of mental illness each year, but only 41% of those affected received mental health care or services in the past year. Brazil has the greatest number of depressed individuals, in Latin America. Adults living in Sao Paulo megacity has prevalence of mental disorders at greater levels than similar surveys conducted in other areas of the world with more than one million adults with serious impairment levels. Discussion: The results show that, despite the vast socioeconomic differences between the three countries, there are correlations regarding mental health prevalence and difficulty to provide adequate services including a lack of awareness of how serious mental illness is, stigma for seeking mental illness, with comorbidity a common phenomenon, and a lack of partnership between different levels of service providers, which weakens mental health service delivery. The findings also indicate that mental health training institutions have a monumental task to prepare personnel to address the future mental health needs in each of the countries compared, which will constitute the next phase of the research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mental%20health%20epidemiology" title="mental
