Given its potential to climate change mitigation, this practice is being recommended as a climate-smart farming practice in the recent years. However, the financial attractiveness of this practice is not well-documented in a labor scarce economy such as Nepal. This study attempts to examine the financial suitability of an agroforestry-based farming practice in the present socio-economic context of Nepal where labor is in short supply. A total of 200 households were randomly selected for household surveys in Dhanusha district during April to July 2015. Two farming practices were found to be dominant in the study area: 1) conventional farming (field crops only) in which at least two field crops are annually grown, and 2) agroforestry-based farming (agroforest, home garden and field crops combined) practice (ABFP). The ABFP was found to be less labor intensive than the conventional farming (137 Man days/yr/ha vs 218 Man days/yr/ha). The ex-ante financial analysis indicated that both the farming practices generated positive NPVs (Net Present Values) and B/C (Benefit-Cost) ratios greater than one, indicating both are financially attractive farming enterprises under the base discount rate of 12%. However, the ABFP generated higher NPV and greater B/C ratio than the conventional farming, indicating the former was financially more attractive than the later. The sensitivity analysis showed that the conventional farming was more sensitive to change in labor wage rate than that of the ABFP. Up to the 24% discount rate, the ABFP generated higher NPV and in case of B/C ratio, the ratio was found greater for ABFP even in 50% discount rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroforestry" title="agroforestry">agroforestry</a>, <a href="https://publications.waset.org/abstracts/search?q=benefit-cost%20analysis" title=" benefit-cost analysis"> benefit-cost analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=conventional%20farming" title=" conventional farming"> conventional farming</a>, <a href="https://publications.waset.org/abstracts/search?q=net%20present%20value" title=" net present value"> net present value</a> </p> <a href="https://publications.waset.org/abstracts/113170/assessing-the-financial-potential-of-an-agroforestry-based-farming-practice-in-a-labor-scarce-subsistence-economy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113170.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">133</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">125</span> Practical Modelling of RC Structural Walls under Monotonic and Cyclic Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20E.%20Sedgh">Reza E.

Dhakal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shear walls have been used extensively as the main lateral force resisting systems in multi-storey buildings. The recent development in performance based design urges practicing engineers to conduct nonlinear static or dynamic analysis to evaluate seismic performance of multi-storey shear wall buildings by employing distinct analytical models suggested in the literature. For practical purpose, application of macroscopic models to simulate the global and local nonlinear behavior of structural walls outweighs the microscopic models. The skill level, computational time and limited access to RC specialized finite element packages prevents the general application of this method in performance based design or assessment of multi-storey shear wall buildings in design offices. Hence, this paper organized to verify capability of nonlinear shell element in commercially available package (Sap2000) in simulating results of some specimens under monotonic and cyclic loads with very oversimplified available cyclic material laws in the analytical tool. The selection of constitutive models, the determination of related parameters of the constituent material and appropriate nonlinear shear model are presented in detail. Adoption of proposed simple model demonstrated that the predicted results follow the overall trend of experimental force-displacement curve. Although, prediction of ultimate strength and the overall shape of hysteresis model agreed to some extent with experiment, the ultimate displacement(significant strength degradation point) prediction remains challenging in some cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20model" title="analytical model">analytical model</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20shell%20element" title=" nonlinear shell element"> nonlinear shell element</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20wall" title=" structural wall"> structural wall</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20behavior" title=" shear behavior"> shear behavior</a> </p> <a href="https://publications.waset.org/abstracts/38386/practical-modelling-of-rc-structural-walls-under-monotonic-and-cyclic-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38386.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">124</span> Leveraging Business to Business Collaborations to Optimize Reverse Haul Logistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pallav%20Singh">Pallav Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Yabaji"> Rajesh Yabaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Dhir"> Rajesh Dhir</a>, <a href="https://publications.waset.org/abstracts/search?q=Chanakya%20Hridaya"> Chanakya Hridaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Supply Chain Costs for the Indian Industries have been on an exponential trend due to steep inflation on fundamental cost factors – Fuel, Labour, Rents. In this changing context organizations have been focusing on adopting multiple approaches to keep logistics costs under control to protect the profit margins. The lever of ‘Business to Business (B2B) collaboration’ can be used by organizations to garner higher value. Given the context of Indian Logistics Industry the penetration of B2B Collaboration initiatives have been limited. This paper outlines a structured framework for adoption of B2B collaboration through discussion of a successful initiative between ITC’s Leaf Tobacco Business and a leading Indian Media House. Multiple barriers to such a collaborative process exist which need to be addressed through comprehensive structured approaches. This paper outlines a generic framework approach to B2B collaboration for the Indian Logistics Space, outlining the guidelines for arriving at potential opportunities, identification of collaborators, effective tie-up process, design of operations and sustenance factors. The generic methods outlined can be used in any other industry and also builds a foundation for further research on many topics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20to%20business%20collaboration" title="business to business collaboration">business to business collaboration</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20haul%20logistics" title=" reverse haul logistics"> reverse haul logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20cost%20optimization" title=" transportation cost optimization"> transportation cost optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=exports%20logistics" title=" exports logistics"> exports logistics</a> </p> <a href="https://publications.waset.org/abstracts/6621/leveraging-business-to-business-collaborations-to-optimize-reverse-haul-logistics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6621.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">328</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">123</span> In-silico Target Identification and Molecular Docking of Withaferin A and Withanolide D to Understand their Anticancer Therapeutic Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Devinder%20Kaur%20Sugga">Devinder Kaur Sugga</a>, <a href="https://publications.waset.org/abstracts/search?q=Ekamdeep%20Kaur"> Ekamdeep Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaspreet%20Kaur"> Jaspreet Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=C.%20Rajesh"> C.

The two main withanolides, namely Withaferin A and Withanolides D, have been extensively studied for their pharmacological activities. Both these withanolides are present in the Withania somnifera (WS) leaves belonging to the family Solanaceae, also known as “Indian ginseng .”In this study effects of WS leaf extract on the MCF7 breast cancer cell line were investigated by performing a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay to evaluate the cytotoxic effects and in vitro wound-healing assay to study the effect on cancer cell migration. Our data suggest WS extracts have cytotoxic effects and are effective anti-migrating agents and thus can be a source of potential candidates for the development of potential agents against metastasis. Thus, it can be a source of potential candidates for the development of potential agents against metastasis. Insight into these results, the in-silico approach to identify the possible protein targets interacting with withanolides was taken. Protein kinase C alpha (PKCα) was among the selected 5 top-ranked target proteins identified by the Swiss Target Prediction tool. PKCα is known to promote the growth and invasion of cancer cells and is being evaluated as a prognostic biomarker and therapeutic target in clinically aggressive tumors. Molecular docking of Withaferin A and Withanolides D was performed using AutoDock Vina. Both the bioactive compounds interacted with PKCα. The targets predicted using this approach will serve as leads for the possible therapeutic potential of withanolides, the bioactive ingredients of WS extracts, as anti-cancer drugs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=withania%20somnifera" title="withania somnifera">withania somnifera</a>, <a href="https://publications.waset.org/abstracts/search?q=withaferin%20A" title=" withaferin A"> withaferin A</a>, <a href="https://publications.waset.org/abstracts/search?q=withanolides%20D" title=" withanolides D"> withanolides D</a>, <a href="https://publications.waset.org/abstracts/search?q=PKC%CE%B1" title=" PKCα"> PKCα</a> </p> <a href="https://publications.waset.org/abstracts/151339/in-silico-target-identification-and-molecular-docking-of-withaferin-a-and-withanolide-d-to-understand-their-anticancer-therapeutic-potential" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151339.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">122</span> Tailoring the Parameters of the Quantum MDS Codes Constructed from Constacyclic Codes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaskarn%20Singh%20Bhullar">Jaskarn Singh Bhullar</a>, <a href="https://publications.waset.org/abstracts/search?q=Divya%20Taneja"> Divya Taneja</a>, <a href="https://publications.waset.org/abstracts/search?q=Manish%20Gupta"> Manish Gupta</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar%20Narula"> Rajesh Kumar Narula</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The existence conditions of dual containing constacyclic codes have opened a new path for finding quantum maximum distance separable (MDS) codes.

In Nepal, the supply of water in both farmer- and agency-managed irrigation systems is inefficient because of the weak institutional frameworks. This type of inefficiency is linked with collective problems such as non-excludability of irrigation water, inadequate recognition of property rights and externalities. Irrigation scheme surveys from Nepal as well as existing literature revealed that the Nepalese irrigation sector is facing many issues such as low cost recovery, inadequate maintenance of the schemes and inefficient allocation and utilization of irrigation water. The institutional practices currently in place also fail to create/force any incentives for farmers to use water efficiently and to pay for its use. This, thus, compels the need of refined institutional framework that can address the collective problems and improve irrigation efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agency-managed" title="agency-managed">agency-managed</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20recovery" title=" cost recovery"> cost recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer-managed" title=" farmer-managed"> farmer-managed</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20design" title=" institutional design"> institutional design</a> </p> <a href="https://publications.waset.org/abstracts/62687/an-alternative-institutional-design-for-efficient-management-of-nepalese-irrigation-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62687.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">120</span> Analysis of Plates with Varying Rigidities Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karan%20Modi">Karan Modi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar"> Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyoti%20Katiyar"> Jyoti Katiyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shreya%20Thusoo"> Shreya Thusoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents Finite Element Method (FEM) for analyzing the internal responses generated in thin rectangular plates with various edge conditions and rigidity conditions.

Out of 75 district, 59 districts have installed 1287 MH projects with a total capacity of 24 Mega Watt (MW). Now, the challenge is how to sustain them. Dolakha is a prominent district for sustainable endues of power to sustain the MH projects. A total of 37 MH projects have been constructed with producing 886 Kilo Watt (KW) of energy in the district. This study traces out the impact of earthquake in MH sector in Dolakha district. It shows that 59 % of projects have been affected by devastating earthquake in April and May, 2015 where 29 % are completely damaged. Most of the damages are in civil structures like Penstock, forebay, power house, Canal, Intake. Transmission and distribution line have been partially damaged. This paper analysis failure of the civil structural component of MH projects and its financial consequence to the community.

Relatively, few studies have enquired on the evolution of Sustainable Municipal Waste Management (SMWM) in Nigeria. The main objective of this research is to examine the evolution of SMWM in Nigeria using Lagos state as a case study. A qualitative method was used as methodology, soft systems analysis is the main tool of evaluation. Results indicated that effective policy implementation and management is the main challenge to the proper evolution of SMWM. These findings highlight the relevance of effective stakeholder’s engagement and management, policy consistency as major determinants in SMWM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20income%20localities" title="high income localities">high income localities</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20middle%20income%20localities" title=" low middle income localities"> low middle income localities</a>, <a href="https://publications.waset.org/abstracts/search?q=SMWM" title=" SMWM"> SMWM</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20middle%20income%20localities" title=" upper middle income localities"> upper middle income localities</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20collection" title=" waste collection"> waste collection</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20disposal" title=" waste disposal"> waste disposal</a> </p> <a href="https://publications.waset.org/abstracts/103338/evolution-of-sustainable-municipal-solid-waste-management-in-nigeria-lagos-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103338.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">153</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">117</span> Inhibitory Effect of Hydroalcoholic Extract of Cestrum Nocturnum on α-Amylase Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar">Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20Kamboj"> Anil Kamboj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inhibition of α- amylase play a vital role in the clinical management of postprandial hyperglycemia.

It enables scholars to interpret and make informed judgments as users of information sources, and it also enables them to become producers of information in their own right, and thereby to become more powerful participants in society. Information literacy is about developing people‘s critical and creative abilities. Digital media – and particularly the Internet – significantly increase the potential for such active participation of the individual, provided scholars have the means and training to effectively access and use them.

However, sometimes complications arise, which lead to the loss of the implant as well as the prosthesis. Fracture of dental implants is rare; however, at times, implants or abutment screws fracture and lead to many problems for the clinician and the patient. Possible causes of implant fracture include improper design, overload, fatigue and corrosion. Six retrieved fractured dental implants, with varying diameters and designs, were collected from time to time to examine by scanning electron microscope (SEM) to characterize fracture behavior and assess the mechanism of fracture. In this investigation, it was observed that fracture of the five dental implants occurred due to fatigue crack initiation and propagation from the thread roots. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium" title="titanium">titanium</a>, <a href="https://publications.waset.org/abstracts/search?q=dental" title=" dental"> dental</a>, <a href="https://publications.waset.org/abstracts/search?q=implant" title=" implant"> implant</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=failure" title=" failure"> failure</a> </p> <a href="https://publications.waset.org/abstracts/171204/failure-analysis-of-fractured-dental-implants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171204.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">81</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">108</span> NOx Emission and Computational Analysis of Jatropha Curcus Fuel and Crude Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vipan%20Kumar%20Sohpal">Vipan Kumar Sohpal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20K%20Sharma"> Rajesh K Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diminishing of conventional fuels and hysterical vehicles emission leads to deterioration of the environment, which emphasize the research to work on biofuels. Biofuels from different sources attract the attention of research due to low emission and biodegradability. Emission of carbon monoxide, carbon dioxide and H-C reduced drastically using Biofuels (B-20) combustion. Contrary to the conventional fuel, engine emission results indicated that nitrous oxide emission is higher in Biofuels. So this paper examines and compares the nitrogen oxide emission of Jatropha Curcus (JCO) B-20% blends with the vegetable oil. In addition to that computational analysis of crude non edible oil performed to assess the impact of composition on emission quality.

Co-axial duct placed in a high pressure chamber is used for the purpose. A gas pressure of 0.1, 0.2 and 0.3 MPa have been considered with a 10:90 SF<sub>6</sub> and N<sub>2</sub> gas mixtures. The 2D and 3D histograms of clean duct and duct with copper particle are discussed in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coaxial%20duct" title="coaxial duct">coaxial duct</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20insulated%20system" title=" gas insulated system"> gas insulated system</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20mixtures" title=" gas mixtures"> gas mixtures</a>, <a href="https://publications.waset.org/abstracts/search?q=metallic%20particle" title=" metallic particle"> metallic particle</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20discharges" title=" partial discharges"> partial discharges</a>, <a href="https://publications.waset.org/abstracts/search?q=histograms" title=" histograms"> histograms</a> </p> <a href="https://publications.waset.org/abstracts/44559/effect-of-copper-particle-on-the-pd-characteristics-in-a-coaxial-duct-with-mixture-of-sf6-10-and-n2-90-gases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44559.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">400</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">106</span> Modern Pedagogy Techniques for DC Motor Speed Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar">Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Roopali%20Dogra"> Roopali Dogra</a>, <a href="https://publications.waset.org/abstracts/search?q=Puneet%20Aggarwal"> Puneet Aggarwal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Based on a survey conducted for second and third year students of the electrical engineering department at Maharishi Markandeshwar University, India, it was found that around 92% of students felt that it would be better to introduce a virtual environment for laboratory experiments. Hence, a need was felt to perform modern pedagogy techniques for students which consist of a virtual environment using MATLAB/Simulink. In this paper, a virtual environment for the speed control of a DC motor is performed using MATLAB/Simulink. The various speed control methods for the DC motor include the field resistance control method and armature voltage control method.

By adding superplasticizer as solution for recover unusable slump loss concrete may affects other concrete properties. Therefore, this paper was observed setting time and compressive strength of concrete after being re-dose with chemical admixture type F (superplasticizer, naphthalene based) for slump recovery. The concrete used in this study was fly ash concrete with fly ash replacement of 0%, 30% and 50% respectively. Concrete mix designed for test specimen was prepared with paste content (ratio of volume of cement to volume of void in the aggregate) of 1.2 and 1.3, water-to-binder ratio (w/b) range of 0.3 to 0.58, initial dose of superplasticizer (SP) range from 0.5 to 1.6%. The setting time of concrete were tested both before and after re-dosed with different amount of second dose and time of dosing. The research was concluded that addition of second dose of superplasticizer would increase both initial and final setting times accordingly to dosage of addition. As for fly ash concrete, the prolongation effect was higher as the replacement of fly ash is increase. The prolongation effect can reach up to maximum about 4 hours. In case of compressive strength, the re-dosed concrete has strength fluctuation within acceptable range of ±10%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title="compressive strength">compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash%20concrete" title=" fly ash concrete"> fly ash concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20dose%20of%20superplasticizer" title=" second dose of superplasticizer"> second dose of superplasticizer</a>, <a href="https://publications.waset.org/abstracts/search?q=setting%20times" title=" setting times"> setting times</a> </p> <a href="https://publications.waset.org/abstracts/41123/study-on-compressive-strength-and-setting-time-of-fly-ash-concrete-after-slump-recovery-using-superplasticizer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41123.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">281</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">104</span> Thinned Elliptical Cylindrical Antenna Array Synthesis Using Particle Swarm Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Bera">Rajesh Bera</a>, <a href="https://publications.waset.org/abstracts/search?q=Durbadal%20Mandal"> Durbadal Mandal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajib%20Kar"> Rajib Kar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakti%20P.%20Ghoshal"> Sakti P.

Similarly, marine bromopyrrole alkaloids are well known for their diverse array of anti-infective properties. Hence, we have reported synthesis and in vitro HIV-1 RT inhibitory activity of a series of 4-thiazolidinone-bromopyrrole alkaloid hybrids tethered with amide linker. The results of in vitro HIV-1 RT kit assay showed that some of the compounds, such as 4c, 4d, and 4i could effectively inhibit RT activity. Among them, compounds 4c having 4-chlorophenyl substituted 4-thiazolidione ring was the best one with the IC50 value of 0.26 µM. The sturdy emerges with key structure-activity relationship that pyrrole-NH-free core benefited inhibition against HIV-1 RT inhibition. This study identified conjugate 4c with potent activity and selectivity as promising compound for further drug development to HIV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antiviral%20drugs" title="antiviral drugs">antiviral drugs</a>, <a href="https://publications.waset.org/abstracts/search?q=bromopyrrole%20alkaloids" title=" bromopyrrole alkaloids"> bromopyrrole alkaloids</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV-1%20RT%20inhibition" title=" HIV-1 RT inhibition"> HIV-1 RT inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=4-thiazolidinone" title=" 4-thiazolidinone"> 4-thiazolidinone</a> </p> <a href="https://publications.waset.org/abstracts/35304/identification-of-synthetic-hybrids-of-4-thiazolidinone-bromopyrrole-alkaloid-as-hiv-1-rt-inhibitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35304.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">459</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">102</span> Performance Analysis of Solar Air Heater with Fins and Perforated Twisted Tape Insert</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar">Rajesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Prabha%20Chand"> Prabha Chand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present paper deals with the analytical investigation on the thermal and thermo-hydraulic performance of the solar air collector fitted with fins and perforated twisted tapes (PTT) of twist ratio 2 with different axial pitch ratio.

In Nepal, the water supply in both farmers’- and agency-managed irrigation systems has become sub-standard because of the weak institutional framework. This study characterizes both forms of the schemes and links existing institution and governance of the schemes with its performance with reference to cost recovery, maintenance of the schemes and water distribution throughout the schemes. For this, two types of surveys were conducted. A management survey of ten farmers’-managed and five agency-managed schemes of Chitwan valley and its periphery was done. Also, a farm survey comprising 25 farmers from each of head, middle and tail regions of both schemes; Narayani Lift Irrigation Project (agency-managed) and Khageri Irrigation System (farmers’-managed) of Chitwan Valley as a case study was conducted. The results showed that cost recovery of agency-managed schemes in 2015 was less than two percent whereas service fee collection rate in farmers’-managed schemes was nearly 2/3rd that triggered poor maintenance of the schemes and unequal distribution of water throughout the schemes. Also, the institution on practice is unable to create any incentives for farmers for economical use of water as well as willingness to pay for its use. This, thus, compels the need of refined institutional framework which has been suggested in this paper aiming to improve the cost recovery and better water distribution throughout the irrigation schemes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost%20recovery" title="cost recovery">cost recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=governance" title=" governance"> governance</a>, <a href="https://publications.waset.org/abstracts/search?q=institution" title=" institution"> institution</a>, <a href="https://publications.waset.org/abstracts/search?q=schemes%27%20performance" title=" schemes' performance"> schemes' performance</a> </p> <a href="https://publications.waset.org/abstracts/54452/institutional-design-for-managing-irrigation-problems-a-case-study-of-farmers-and-agency-managed-irrigation-systems-of-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54452.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">260</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">99</span> Dynamic Soil Structure Interaction in Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shreya%20Thusoo">Shreya Thusoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Karan%20Modi"> Karan Modi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Kumar%20Jha"> Ankit Kumar Jha</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Kumar"> Rajesh Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the evolution of computational tools and simulation software, there has been considerable increase in research on Soil Structure Interaction (SSI) to decrease the computational time and increase accuracy in the results.

LEDs are low-voltage light sources, requiring a constant DC voltage or current to operate optimally. LEDs, therefore, require a device that can convert incoming AC power to the proper DC voltage, and regulate the current flowing through the LED during operation. Proposed topology has a front end converter. It is an AC-DC rectifier that works on bridgeless boost topology which shapes the input current waveform. The front end converter is followed by a DC-DC converter which provides a constant DC voltage across the LEDs. A 12V AC input is given to the input of frontend converter which rectifies and boost the voltage to 24v DC and gives it to the DC-DC converter. The DC-DC converter converts the 24V DC and regulates this constant DC voltage across the LEDs. <p class="card-text"><strong>Keywords:</strong> <a
