Its optical, optoelectronic, and structural properties are of practical importance along with its exciton dynamics. Exciton, along with exciton complexes, plays a vital role in realizing quantum devices. MoS₂ monolayers were synthesized using chemical vapour deposition (CVD) technique on SiO₂ and hBN substrates. Photoluminescence spectroscopy (PL) was used to identify the monolayer, which also reflects the substrate based peak broadening due to screening effects. In-plane and out of plane characteristic vibrational modes E¹₂g and A₁g, respectively, were detected in a different configuration on the substrate. The B-excitons and trions showed a dominant feature at low temperatures due to electron-phonon coupling effects, whereas their energies are separated by 100 meV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2D%20materials" title="2D materials">2D materials</a>, <a href="https://publications.waset.org/abstracts/search?q=photoluminescence" title=" photoluminescence"> photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=AFM" title=" AFM"> AFM</a>, <a href="https://publications.waset.org/abstracts/search?q=excitons" title=" excitons"> excitons</a> </p> <a href="https://publications.waset.org/abstracts/114832/controlling-excitons-complexes-in-two-dimensional-mos2-monolayers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114832.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">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Stress Analysis of Turbine Blades of Turbocharger Using Structural Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kalvin">Roman Kalvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anam%20Nadeem"> Anam Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Arif"> Saba Arif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Turbocharger is a device that is driven by the turbine and increases efficiency and power output of the engine by forcing external air into the combustion chamber. This study focused on the distribution of stress on the turbine blades and total deformation that may occur during its working along with turbocharger to carry out its static structural analysis of turbine blades. Structural steel was selected as the material for turbocharger. Assembly of turbocharger and turbine blades was designed on PRO ENGINEER. Furthermore, the structural analysis is performed by using ANSYS. This research concluded that by using structural steel, the efficiency of engine is improved and by increasing number of turbine blades, more waste heat from combustion chamber is emitted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turbocharger" title="turbocharger">turbocharger</a>, <a href="https://publications.waset.org/abstracts/search?q=turbine%20blades" title=" turbine blades"> turbine blades</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20steel" title=" structural steel"> structural steel</a>, <a href="https://publications.waset.org/abstracts/search?q=ANSYS" title=" ANSYS"> ANSYS</a> </p> <a href="https://publications.waset.org/abstracts/97552/stress-analysis-of-turbine-blades-of-turbocharger-using-structural-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97552.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Direct Torque Control of Induction Motor Employing Teaching Learning Based Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Gopi">Anam Gopi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The undesired torque and flux ripple may occur in conventional direct torque control (DTC) induction motor drive.

Scorzocreticin, Annulatomarin, Montroumarin, and Thunberginol B, have been carried out starting from 3,5-dimethoxy-4-methylphenyl acetic acid. 3,5-Dimethoxy-4-methylphenyl acetic acid was then condensed with various aryl acid chlorides (a-e) to afford the corresponding 6,8-dimethoxy-7-methyl-3-aryl isocoumarins (5a-e). The alkaline hydrolysis of isocoumarins yields keto-acids (3a-e), which were then reduced to hydroxyacids, followed by cyclodehydration with acetic anhydride furnish corresponding 3,4-dihydroisocoumarins (7a-e). Finally, demethylation of 3,4-dihydroisocoumarins was carried out to afford 6,8-dihydroxy-7-methyl-3-aryl-3,4-dihydroisocoumarins (7a-e). Antibacterial evaluation of all the synthesized compounds were carried out against ten bacterial strains, it was concluded that isocoumarins (5a-e) and 3,4-dihydroisocoumarins (7a-e) are more active against gram positive bacteria then gram negative. However, the 6,8-dihydroxy-3,4-dihydroisocoumarin derivatives (8a-e) are more active against gram negative then gram positive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3" title="3">3</a>, <a href="https://publications.waset.org/abstracts/search?q=5-Dimethoxy-4-methylhomophthalic%20acid" title="5-Dimethoxy-4-methylhomophthalic acid">5-Dimethoxy-4-methylhomophthalic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%203" title=" natural 3"> natural 3</a>, <a href="https://publications.waset.org/abstracts/search?q=4-Dihydroisocoumarin%20analogues" title="4-Dihydroisocoumarin analogues">4-Dihydroisocoumarin analogues</a>, <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20activity" title=" antibacterial activity"> antibacterial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=isocoumarins" title=" isocoumarins"> isocoumarins</a>, <a href="https://publications.waset.org/abstracts/search?q=demethylation" title=" demethylation "> demethylation </a> </p> <a href="https://publications.waset.org/abstracts/30511/synthesis-and-antibacterial-evaluation-of-natural-bioactive-34-dihydroisocoumarinanalogues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30511.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">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Organizational Learning, Job Satisfaction and Work Performance among Nurses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafia%20Rafique">Rafia Rafique</a>, <a href="https://publications.waset.org/abstracts/search?q=Arifa%20Khadim"> Arifa Khadim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research investigates the moderating role of job satisfaction between organizational learning and work performance among nurses. Correlation research design was used. Non-probability purposive sampling technique was utilized to recruit a sample of 110 nurses from public hospitals situated in the city of Lahore. The construct of organizational learning was measured using subscale of Integrated Scale for Measuring Organizational Learning. Job satisfaction was measured with the help of Job Satisfaction Survey. Performance of employees (task performance, contextual performance and counterproductive work behavior) was assessed by Individual Work Performance Questionnaire. Job satisfaction negatively moderates the relationship between organizational learning and counterproductive work behavior. Education has a significant positive relationship with organizational learning. Age, current hospital experience, marital satisfaction and salary of the nurses have positive relationship while number of children has significant negative relationship with counterproductive work behavior. These outcomes can be insightful in understanding the dynamics involved in work performance. Based on the result of this study relevant solutions can be proposed to improve the work performance of nurses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=counterproductive%20work%20behavior" title="counterproductive work behavior">counterproductive work behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=nurses" title=" nurses"> nurses</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20learning" title=" organizational learning"> organizational learning</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20performance" title=" work performance"> work performance</a> </p> <a href="https://publications.waset.org/abstracts/71137/organizational-learning-job-satisfaction-and-work-performance-among-nurses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71137.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31</span> Event Extraction, Analysis, and Event Linking</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Alam">Anam Alam</a>, <a href="https://publications.waset.org/abstracts/search?q=Rahim%20Jamaluddin%20Kanji"> Rahim Jamaluddin Kanji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid growth of event in everywhere, event extraction has now become an important matter to retrieve the information from the unstructured data.

However, no clarity on the mechanisms responsible for the neuroprotective effects of RW-9 peptide against AD-like symptoms. Herein, it found that RW-9 intervention showed various improving effects in cognitive-behavioral tests and alleviated oxidative stress and inflammation in the scopolamine-induced mice model. The hippocampus proteomics analysis revealed the upregulation of memory-related proteins, including Grin3a, Ppp2r1b, Stat6, Pik3cd, Slc5a7, Chrm2, mainly involved in cAMP signaling, PI3K-Akt signaling, and JAK-STAT signaling pathways. The administration of RW-9 significantly upregulated the neurotransmitters, including 5-HT, DA, and Arg, in mice brains. Moreover, it regulated the serum metabolic profile and increased the expression levels of ABC transporters, biosynthesis of amino acids, and Amino acyl-tRNA biosynthesis, among others. The 16s-rRNA results illustrated that the RW-9 restored the abundance of Muribaculaceae, Lachnospiraceae, Lactobacillus, Clostridia and Bactericides. Taken together, our results suggest that the RW-9 may prevent the AD-like symptoms via modulation of the gut-serum-brain axis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oat%20protein" title="oat protein">oat protein</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20peptide" title=" active peptide"> active peptide</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprotective" title=" neuroprotective"> neuroprotective</a>, <a href="https://publications.waset.org/abstracts/search?q=gut-brain%20axis" title=" gut-brain axis"> gut-brain axis</a> </p> <a href="https://publications.waset.org/abstracts/189320/effect-of-oat-protein-peptide-in-cognitive-impairment-mice-via-mediating-gut-brain-axis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/189320.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">27</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Energy Analysis of Seasonal Air Conditioning Demand of All Income Classes Using Bottom up Model in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saba%20Arif">Saba Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Anam%20Nadeem"> Anam Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kalvin"> Roman Kalvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Tanzeel%20Rashid"> Tanzeel Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Burhan%20Ali"> Burhan Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Juntakan%20Taweekun"> Juntakan Taweekun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, the energy crisis is taking serious attention. Globally, industries and building are major share takers of energy. 72% of total global energy is consumed by residential houses, markets, and commercial building. Additionally, in appliances air conditioners are major consumer of electricity; about 60% energy is used for cooling purpose in houses due to HVAC units. Energy demand will aid in determining what changes will be needed whether it is the estimation of the required energy for households or instituting conservation measures. Bottom-up model is one of the most famous methods for forecasting. In current research bottom-up model of air conditioners' energy consumption in all income classes in comparison with seasonal variation and hourly consumption is calculated. By comparison of energy consumption of all income classes by usage of air conditioners, total consumption of actual demand and current availability can be seen. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning" title="air conditioning">air conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=bottom%20up%20model" title=" bottom up model"> bottom up model</a>, <a href="https://publications.waset.org/abstracts/search?q=income%20classes" title=" income classes"> income classes</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20demand" title=" energy demand"> energy demand</a> </p> <a href="https://publications.waset.org/abstracts/83887/energy-analysis-of-seasonal-air-conditioning-demand-of-all-income-classes-using-bottom-up-model-in-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83887.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">248</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Axisymmetric Rotating Flow over a Permeable Surface with Heat and Mass Transfer Effects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Faraz">Muhammad Faraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Talat%20Rafique"> Talat Rafique</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang%20Min%20Park"> Jang Min Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, rotational flow above a permeable surface with a variable free stream angular velocity is considered. Main interest is to solve the associated heat/mass transport equations under different situations. Firstly, heat transport phenomena occurring in generalized vortex flow are analyzed under two altered heating processes, namely, the (i) prescribed surface temperature and (ii) prescribed heat flux. The vortex motion imposed at infinity is assumed to follow a power-law form 〖(r/r_0)〗^((2n-1)) where r denotes the radial coordinate, r_0 the disk radius, and n is a power-law parameter. Assuming a similar solution, the governing Navier-Stokes equations transform into a set of coupled ODEs which are treated numerically for the aforementioned thermal conditions. Secondly, mass transport phenomena accompanied by activation energy are incorporated into the generalized vortex flow situation. After finding self-similar equations, a numerical solution is furnished by using MATLAB's built-in function bvp4c. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=b%C3%B6dewadt%20flow" title="bödewadt flow">bödewadt flow</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20flow" title=" vortex flow"> vortex flow</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20flows" title=" rotating flows"> rotating flows</a>, <a href="https://publications.waset.org/abstracts/search?q=prescribed%20heat%20flux" title=" prescribed heat flux"> prescribed heat flux</a>, <a href="https://publications.waset.org/abstracts/search?q=permeable%20surface" title=" permeable surface"> permeable surface</a>, <a href="https://publications.waset.org/abstracts/search?q=activation%20energy" title=" activation energy"> activation energy</a> </p> <a href="https://publications.waset.org/abstracts/179351/axisymmetric-rotating-flow-over-a-permeable-surface-with-heat-and-mass-transfer-effects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179351.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">25</span> The Impact of Corporate Social Responsibility and Relationship Marketing on Relationship Maintainer and Customer Loyalty by Mediating Role of Customer Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Bhatti">Anam Bhatti</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumbal%20Arif"> Sumbal Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariam%20Mehar"> Mariam Mehar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sohail%20Younas"> Sohail Younas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CSR has become one of the imperative implements in satisfying customers.

For this purpose, previous records have been collected from authentic data resources and for the attainment of present values, several samples were collected from three major locations of the Buriganga River during summer and winter seasons in 2018 to determine the distribution and variation of water quality parameters. Samples were collected six ft below the river water surface. Analysis indicates slightly acidic to slightly alkaline (6.8-7.49) in nature. Bio-Chemical Oxygen Demand, Total Dissolved Solids, Total Solids (TS) & Total Suspended Solids (TSS) have been found greater in summer. On the other hand, Dissolved Oxygen is found greater in rainy seasons. Relocation shows improvement in water quality parameters. Though the improvement related to relocation of tannery industry is not adequate to turn the water body to be an inhabitable place for aquatic lives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Buriganga%20river" title="Buriganga river">Buriganga river</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20pollution" title=" river pollution"> river pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=tannery%20industry" title=" tannery industry"> tannery industry</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20parameters" title=" water quality parameters"> water quality parameters</a> </p> <a href="https://publications.waset.org/abstracts/95752/an-investigation-into-the-impact-of-the-relocation-of-tannery-industry-on-water-quality-parameters-of-urban-river-buriganga" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95752.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Design and Implementation of Power Generation Mechanism Using Speed Breaker</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kalvin">Roman Kalvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anam%20Nadeem"> Anam Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Arif"> Saba Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Juntakan%20Taweekun"> Juntakan Taweekun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current scenario demand of power is increasing day by day with increasing population. It is needed to sort out this problem with a technique which will not only overcome this energy crisis but also should be environment friendly. This project emphasizes on idea which shows that power could be generated by specially designed speed breaker. This project shows clearly how power can be generated by using Cam Mechanism where basically linear motion is converted into rotatory motion that can be used to generate electricity. When vehicle passes over the speed breaker, presses the cam with the help of connecting rod which rotate main shaft attached with large pulley. A flywheel is coupled with the shaft whose purpose is to normalize the oscillation in the energy and to make the energy unvarying. So, the shafts will spin with firm rpm. These shafts are coupled from end to end with a belt drive. The results show that power generated from this mechanism is 12 watts. The generated electricity does not required any fuel consumption it only generates power which can be used for the street light as well as for the traffic signals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=revolution%20per%20minute" title="revolution per minute">revolution per minute</a>, <a href="https://publications.waset.org/abstracts/search?q=RPM" title=" RPM"> RPM</a>, <a href="https://publications.waset.org/abstracts/search?q=cam" title=" cam"> cam</a>, <a href="https://publications.waset.org/abstracts/search?q=speed%20breaker" title=" speed breaker"> speed breaker</a>, <a href="https://publications.waset.org/abstracts/search?q=rotatory%20motion" title=" rotatory motion"> rotatory motion</a> </p> <a href="https://publications.waset.org/abstracts/88612/design-and-implementation-of-power-generation-mechanism-using-speed-breaker" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88612.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">213</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Audit of Urgent and Non-Urgent Patient Visits to the Emergency: A Case-Control Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peri%20Harish%20Kumar">Peri Harish Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafique%20Umer%20Harvitkar"> Rafique Umer Harvitkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The emergency department mandates maximum efficacy in the utilization of the available resources. Non-urgent patient visits pose a serious concern to the treatment, patient triage, and resources available. Aims and Objectives: We conducted a retrospective case-control study of the emergency department patient list from October 2019 to November 2022. A total of 839 patients formed part of the study. Somatic complaints, vital signs, diagnostic test results, admission to the hospital, etc., were some of the criteria used for the categorization of patients. Results: The proportion of non-urgent visits varied from 7.2% to 43%, with a median of 21%. Somatic complaints were the least associated with further hospital admissions (n=28%), while diagnostic test results were the most significant indicator of further hospital admissions (n=74%). Effective triage helped minimize emergency department admissions by 36%. Conclusion: Our study shows that effective triaging, patient counselling, and round-the-clock consumable monitoring helped in the effective management of patients admitted and also significantly helped provide treatment to the patients most in need. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urgent%20visits" title="urgent visits">urgent visits</a>, <a href="https://publications.waset.org/abstracts/search?q=non-urgent%20visits" title=" non-urgent visits"> non-urgent visits</a>, <a href="https://publications.waset.org/abstracts/search?q=traiging" title=" traiging"> traiging</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20department%20admissions" title=" emergency department admissions"> emergency department admissions</a> </p> <a href="https://publications.waset.org/abstracts/161095/audit-of-urgent-and-non-urgent-patient-visits-to-the-emergency-a-case-control-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161095.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">112</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Stress Analysis of Spider Gear Using Structural Steel on ANSYS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kalvin">Roman Kalvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Anam%20Nadeem"> Anam Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahab%20Khushnood"> Shahab Khushnood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Differential is an integral part of four wheeled vehicle, and its main function is to transmit power from drive shaft to wheels. Differential assembly allows both rear wheels to turn at different speed along curved paths. It consists of four gears which are assembled together namely pinion, ring, spider and bevel gears. This research focused on the spider gear and its static structural analysis using ANSYS. The main aim was to evaluate the distribution of stresses on the teeth of the spider gear. This study also analyzed total deformation that may occur during its working along with bevel gear that is meshed with spider gear. Structural steel was chosen for spider gear in this research. Modeling and assembling were done on SolidWorks for both spider and bevel gear. They were assembled exactly same as in a differential assembly. This assembly was then imported to ANSYS. After observing results that maximum amount of stress and deformation was produced in the spider gear, it was concluded that structural steel material for spider gear possesses greater amount of strength to bear maximum stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANSYS" title="ANSYS">ANSYS</a>, <a href="https://publications.waset.org/abstracts/search?q=differential" title=" differential"> differential</a>, <a href="https://publications.waset.org/abstracts/search?q=spider%20gear" title=" spider gear"> spider gear</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20steel" title=" structural steel"> structural steel</a> </p> <a href="https://publications.waset.org/abstracts/96019/stress-analysis-of-spider-gear-using-structural-steel-on-ansys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96019.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">185</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Design, Modification and Structural Analysis of Bicycle Sprocket Using ANSYS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kalvin">Roman Kalvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Arif"> Saba Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Anam%20Nadeem"> Anam Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Burhan%20Ali%20Ghumman"> Burhan Ali Ghumman</a>, <a href="https://publications.waset.org/abstracts/search?q=Juntakan%20Taweekun"> Juntakan Taweekun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bicycles are important parts of the transportation industry. In the current world, use of sprocket is very high on bicycles these days. Sprocket and chains are important parts of the transmission of power in the bicycle. However, transmission of power is highly dependent on sprocket design. In conventional bicycles, sprockets are made up of mild steel which undergoes wear and tears with the passage of time due to high pressures applied on it. In the current research, a new sprocket is designed by changing its structure and material to carbon fiber from mild steel. The existing sprocket of a bicycle is compared with the new and modified sprocket design. However, new design has structural and material changes as well. According to the results, in carbon fiber, sprocket deformation is 0.091 mm while sprocket stress value is 371.13N/mm². Also, comparison based analysis is done by physical testing and software analysis. There is 8.1% variation in software and experimental results of steel. Additionally, the difference between both methods comes 8 to 9%. This improved design can be used in future for more durability and long run timings for bicycles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sprocket" title="sprocket">sprocket</a>, <a href="https://publications.waset.org/abstracts/search?q=mild%20steel" title=" mild steel"> mild steel</a>, <a href="https://publications.waset.org/abstracts/search?q=drafting" title=" drafting"> drafting</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation" title=" deformation"> deformation</a> </p> <a href="https://publications.waset.org/abstracts/92837/design-modification-and-structural-analysis-of-bicycle-sprocket-using-ansys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92837.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">254</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> Functionalized Mesoporous Silica: Absorbents for Water Purification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saima%20Nasreen">Saima Nasreen</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzaira%20Rafique"> Uzaira Rafique</a>, <a href="https://publications.waset.org/abstracts/search?q=Shery%20Ehrman"> Shery Ehrman</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Aqeel%20Ashraf"> Muhammad Aqeel Ashraf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The release of heavy metals into the environment is a potential threat to water and soil quality as well as to plant, animal and human health. In current research work, organically functionalized mesoporous silicates (MSU-H) were prepared by the co-condensation between sodium silicate and oregano alkoxysilanes in the presence of the nonionic surfactant triblock copolymer P104. The surfactant was used as a template for improving the porosity of the hybrid gels. Synthesized materials were characterized by TEM, FT-IR, SEM/EDX, TG, surface area analysis. The surface morphology and textural properties of such materials varied with various kinds of groups in the channels. In this study, removal of some heavy metals ions from aqueous solution by adsorption process was investigated. Batch adsorption studies show that the adsorption capacity of metal ions on the functionalized silicates is more than that on pure MSU-H. Data shows adsorption on synthesized materials is a time efficient process, suggesting adsorption on external surface as well as the mesoporous process. Adsorption models of Langmuir, Freundlich, and Temkin depicted equal goodness for all adsorbents, whereas pseudo 2nd order kinetics is in best agreement with experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title="heavy metals">heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=mesoporous%20silica" title=" mesoporous silica"> mesoporous silica</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid" title=" hybrid"> hybrid</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=freundlich" title=" freundlich"> freundlich</a>, <a href="https://publications.waset.org/abstracts/search?q=langmuir" title=" langmuir"> langmuir</a>, <a href="https://publications.waset.org/abstracts/search?q=temkin" title=" temkin"> temkin</a> </p> <a href="https://publications.waset.org/abstracts/39518/functionalized-mesoporous-silica-absorbents-for-water-purification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39518.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">267</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Fear of Negative Evaluation, Social Support and Wellbeing in People with Vitiligo</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafia%20Rafique">Rafia Rafique</a>, <a href="https://publications.waset.org/abstracts/search?q=Mutmina%20Zainab"> Mutmina Zainab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study investigated the relationship between fear of negative evaluation (FNE), social support and well-being in people with Vitiligo. It was hypothesized that low level of FNE and greater social support is likely to predict well-being. It was also hypothesized that social support is likely to moderate the relationship between FNE and well-being. Correlational research design was used for the present study. Non-probability purposive sampling technique was used to collect a sample (N=122) of people with Vitiligo. Hierarchical Moderated Regression analysis was used to test prediction and moderation. Brief Fear of Negative Evaluation Scale, Multidimensional Scale of Perceived Social Support (MSPSS) and Mental Health Continuum-Short form (MHC-SF) were used to evaluate the study variables. Fear of negative evaluation negatively predicted well-being (emotional and psychological). Social support from significant others and friends predicted social well-being. Social Support from family predicted emotional and psychological well-being. It was found that social support from significant others moderated the relationship between FNE and emotional well-being and social support from family moderated the relationship between FNE and social well-being. Dermatologists treating people with Vitiligo need to educate them and their families about the buffering role of social support (family and significant others). Future studies need to focus on other important mediating factors that can possibly explain the relationship between fear of negative evaluation and wellbeing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fear%20of%20negative%20evaluation" title="fear of negative evaluation">fear of negative evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20moderated%20regression" title=" hierarchical moderated regression"> hierarchical moderated regression</a>, <a href="https://publications.waset.org/abstracts/search?q=vitiligo" title=" vitiligo"> vitiligo</a>, <a href="https://publications.waset.org/abstracts/search?q=well-being" title=" well-being"> well-being</a> </p> <a href="https://publications.waset.org/abstracts/70611/fear-of-negative-evaluation-social-support-and-wellbeing-in-people-with-vitiligo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70611.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">302</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> Quality Assurance in Cardiac Disorder Detection Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Naveed">Anam Naveed</a>, <a href="https://publications.waset.org/abstracts/search?q=Asma%20Andleeb"> Asma Andleeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehreen%20Sirshar"> Mehreen Sirshar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the article, Image processing techniques have been applied on cardiac images for enhancing the image quality. Two types of methodologies considers for survey, invasive techniques and non-invasive techniques. Different image processes for improvement of cardiac image quality and reduce the amount of radiation exposure for invasive techniques are explored. Different image processing algorithms for enhancing the noninvasive cardiac image qualities are described. Beside these two methodologies, third methodology has applied on live streaming of heart rate on ECG window for extracting necessary information, removing noise and enhancing quality. Sensitivity analyses have been carried out to investigate the impacts of cardiac images for diagnosis of cardiac arteries disease and how the enhancement on images will help the cardiologist to diagnoses disease. The paper evaluates strengths and weaknesses of different techniques applied for improved the image quality and draw a conclusion. Some specific limitations must be considered for whole survey, like the patient heart beat must be 70-75 beats/minute while doing the angiography, similarly patient weight and exposure radiation amount has some limitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cardiac%20images" title="cardiac images">cardiac images</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20angiography" title=" CT angiography"> CT angiography</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20analysis" title=" critical analysis"> critical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20radiation" title=" exposure radiation"> exposure radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20techniques" title=" invasive techniques"> invasive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=invasive%20techniques" title=" invasive techniques"> invasive techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=non-invasive%20techniques" title=" non-invasive techniques"> non-invasive techniques</a> </p> <a href="https://publications.waset.org/abstracts/26171/quality-assurance-in-cardiac-disorder-detection-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26171.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">352</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">16</span> Impact Analysis of Cultivation of Jatropha Tree on Fuel Prices and Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saba%20Arif">Saba Arif</a>, <a href="https://publications.waset.org/abstracts/search?q=Anam%20Nadeem"> Anam Nadeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Kalvin"> Roman Kalvin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muzaffar%20Ali"> Muzaffar Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Burhan%20Ali"> Burhan Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Juntakan%20Taweekun"> Juntakan Taweekun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Globally transportation sector accounts for around 25% of energy demand and nearly 62% of oil consumed. Therefore, new energy sources are required to introduce for this huge demand replenishment of depleting conventional energy sources. Currently, biofuels such as Jatropha trees as an energy carrier for transportation sector are being utilized effectively round the globe. However, climate conditions at low altitudes with an average annual temperature above 20 degrees Celsius and rainfall of 300-1000mm are considered the most suitable environment for the efficient growth of Jatropha trees. The current study is providing a theoretical survey-based analysis to investigate the effect of rate of cultivation of jatropha trees on the reduction of fuel prices and its environmental benefits. The resulted study shows that jatropha tree’s 100 kg seeds give 80kg oil and the conversion process cost is very small as 890 PKR. Moreover, the extraction of oil from Jatropha tree is tax-free compared to other fuels. The analysis proved very essential for potential assessment of Jatropha regarding future energy fuel for transportation sector at global level. Additionally, it can be very beneficial for increment in the total amount of transportation fuel in Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=jatropha%20tree" title="jatropha tree">jatropha tree</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact" title=" environmental impact"> environmental impact</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20contents" title=" energy contents"> energy contents</a>, <a href="https://publications.waset.org/abstracts/search?q=theoretical%20survey" title=" theoretical survey"> theoretical survey</a> </p> <a href="https://publications.waset.org/abstracts/83886/impact-analysis-of-cultivation-of-jatropha-tree-on-fuel-prices-and-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83886.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">219</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> Identification of Active Phytocomponents in the Ethyl Acetate Extract of Glycosmis pentaphylla Retz.

Traditionally, leaves are useful in fever, hepatopathy, eczema, skin disease, helminthiasis, wounds, and erysipelas. The fruits are sweet and are useful in vitiated conditions of vata, kapha, cough, and bronchitis. The roots are good for facial inflammations, rheumatism, jaundice, and anemia. The preliminary phytochemical investigations indicated the presence of alkaloids, terpenoids, flavonoids, tannins, sugar, glycoside, and phenolic compounds. In the present study, the root part of <em>Glycosmis pentaphylla</em> was used, and the root was collected from Western Ghats of South India. The root was sun/shade dried and pulverized to powder in a mechanical grinder. The powder was successively extracted with various solvents, and the ethyl acetate extract of <em>Glycosmis pentaphylla</em> has been subjected to the GC-MS analysis. Amongst the 46 chemical constituents identified from this plant, three major phytoconstituents were reported for the first time. Marmesin, a furanocumarin compound with the chemical structure 7H-Furo (3,2-G) (1)Benzopyran-7-one,2,3–dihydro–2 - (1-Hydroxy-1methylethyl)-(s) is one of the three compounds identified for the first time at the concentration of 11-60% in ethyl acetate extract of <em>Glycosmis pentaphylla</em>.

Method: It is a case-control study with a sample size of 150. There were 100 suspected cancer cases, 25 healthy controls, and 25 diagnosed cancer cases. To analyze SSAT-1 mRNA expression in whole blood, Zymo Research Quick-RNA Miniprep and Innu SCRIPT—One Step RT-PCR Syber Green kits were used. Patients were divided into three groups: 100 suspected cancer cases, 25 controls, and 25 confirmed breast cancer cases. Result: The total mRNA was isolated, and the expression of SSAT-1 was measured using RT-qPCR. The threshold cycle (Ct) values were used to determine the amount of each mRNA. Ct values were then calculated by taking the difference between the CtSSAT-1 and Ct GAPDH, and further Ct values were calculated with the median absolute deviation for all the samples within the same experimental group. Samples that did not correlate with the results were taken as outliers and excluded from the analysis. The relative fold change is shown as 2^-Ct values. Suspected cases showed a maximum fold change of 32.24, with a control fold change of 1.31. Conclusion: The study reveals an overexpression of SSAT-1 in breast cancer. Furthermore, we can use SSAT-1 as a diagnostic, prognostic, and therapeutic marker for early diagnosis of cancer. <p class="card-text"><strong>Keywords:</strong> <a
