The design of the handle is based on ergonomic principles and tries to avoid awkward postures for surgeons. The handle combines the so-called power-grip and accurate-grip in order to provide strength and accuracy in the performance of surgery. The handle is tested using both objective and subjective approaches. The objective approach uses motion capture techniques to obtain the angles of forearm, arm, wrist and hand. The muscular effort is obtained with electromyography electrodes. On the other hand, a subjective survey has been carried out using questionnaires. Results confirm that the handle is preferred by the majority of the surgeons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laparoscopic%20surgery" title="laparoscopic surgery">laparoscopic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title=" ergonomics"> ergonomics</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20design" title=" mechanical design"> mechanical design</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a> </p> <a href="https://publications.waset.org/abstracts/41496/an-ergonomic-handle-design-for-instruments-in-laparoscopic-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41496.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">502</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> Sensory Evaluation of Meat from Broilers Bird Fed Detoxified Jatropher Curcas and that Fed Conventional Feed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20S.%20Lawal">W.

Simulation from the posterior is readily implemented using a Gibbs sampling algorithm. The Gibbs sampling is implemented even when using conditional densities that are incompatible or only compatible with an improper joint density.

Every year, this need grows even more urgent the more scientific and technological inventions advance. Due to this fact, we find that majority of the research related to energy and power has been focused on finding new and innovative ways to produce power. Furthermore, we observe that because of the environmental state of our world today and the impact of climate change, one of the most explored routes of study has been the use of renewable energies. In this paper, we will be looking at one of the oldest forms of renewable energy, hydroelectric energy. First off, an overview of its history, sources, technical aspects, and applications will be evaluated. After which, we will then proceed to understand the main benefits and drawbacks of this form of renewable energy and offer insights on how it can be better utilized in our world today. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydropower" title="hydropower">hydropower</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroelectric%20energy" title=" hydroelectric energy"> hydroelectric energy</a>, <a href="https://publications.waset.org/abstracts/search?q=advantages" title=" advantages"> advantages</a>, <a href="https://publications.waset.org/abstracts/search?q=disadvantages" title=" disadvantages"> disadvantages</a> </p> <a href="https://publications.waset.org/abstracts/146239/advantages-and-disadvantages-of-hydroelectric-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146239.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">143</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> An Analysis of Telugu Proverbs in the Light of Endangerment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther">Esther</a>, <a href="https://publications.waset.org/abstracts/search?q=Queeny"> Queeny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main goal of this paper is to reflect on the overwhelming, rich folklore of Telugu people through their proverbs, which are assumed to be in a state of endangerment. In order to prove the statement made that the proverbs in Telugu are endangered, we have to delve deeper. We hardly found two or three papers related to Telugu proverbs. So, though the process was weary of sorting out the different proverbs in Telugu, to translate them etc. we found it necessary to do a survey in the form of a questionnaire and draw conclusions so that we could address this issue to the readers. We began with a basic assumption that the older generation may have a wider knowledge of their folklore when compared to the younger generation. The results obtained are quite remarkable, which strengthened our assumptions. Statistical analysis was adopted for quantitative analysis. Through this paper, we hope to kindle cultural awareness among the youngsters regarding the use of one’s own mother tongue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sociolinguistics" title="sociolinguistics">sociolinguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=Telugu%20proverbs" title=" Telugu proverbs"> Telugu proverbs</a>, <a href="https://publications.waset.org/abstracts/search?q=folklore" title=" folklore"> folklore</a>, <a href="https://publications.waset.org/abstracts/search?q=endangerment" title=" endangerment"> endangerment</a> </p> <a href="https://publications.waset.org/abstracts/142079/an-analysis-of-telugu-proverbs-in-the-light-of-endangerment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142079.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">208</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">103</span> On Mathematical Modelling and Optimization of Emerging Trends Processes in Advanced Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agarana%20Michael%20C.">Agarana Michael C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinlabi%20Esther%20T."> Akinlabi Esther T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Pule%20Kholopane"> Pule Kholopane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Innovation in manufacturing process technologies and associated product design affects the prospects for manufacturing today and in near future.

The objective of this study was to find out if there are differences in receptive vocabulary between adolescence and adulthood. In this research, 30 people with DS between 11 and 40 years old, divided into two age ranges (11-18; 19 - 30) and matched in mental age, were evaluated through the Peabody Vocabulary Test. The results show significant differences between both groups in favor of the group with the oldest chronological age and a direct correlation between chronological age and receptive vocabulary development, regardless of mental age. These data support the natural evolution of the passive lexicon in people with DS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=down%20syndrome" title="down syndrome">down syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a>, <a href="https://publications.waset.org/abstracts/search?q=receptive%20vocabulary" title=" receptive vocabulary"> receptive vocabulary</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=adults" title=" adults"> adults</a> </p> <a href="https://publications.waset.org/abstracts/141514/receptive-vocabulary-development-in-adolescents-and-adults-with-down-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141514.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">202</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">101</span> Spontaneous Generation of Wrinkled Patterns on pH-Sensitive Smart-Hydrogel Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carmen%20M.%20Gonzalez-Henriquez">Carmen M.

Additionally, the inhibition of bacterial growth and, therefore, their antimicrobial activity, can be used as dual-functional antifogging/antimicrobial polymer coatings. According to their interesting physicochemical characteristics and biocompatible properties, DMAEMA was used as a monomer to synthesize a smart pH-sensitive hydrogel, namely poly(HEMA-co-PEGDA575-co-DMAEMA). Thus, different mole ratios (ranging from 5:1:0 to 0:1:5, according to the mole ratio between HEMA, PEGDA, and DEAEMA, respectively) were used in this research. The surface patterns formed via a two-step polymerization (redox- and photo-polymerization) were first chemically studied via 1H-NMR and elemental analysis. Secondly, the samples were morphologically analyzed by using Field-Emission Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM) techniques. Then, a particular relation between HEMA, PEGDA, and DEAEMA (0:1:5) was also characterized at three different pH (5.4, 7.4 and 8.3). The hydrodynamic radius and zeta potential of the micro-hydrogel particles (emulsion) were carried out as a possible control for morphology, exploring the effect that produces hydrogel micelle dimensions in the wavelength, height, and roughness of the wrinkled patterns. Finally, contact angle and cross-hatch adhesion test was carried out for the hydrogels supported on glass using TSM-silanized surfaces in order to measure their mechanical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wrinkled%20patterns" title="wrinkled patterns">wrinkled patterns</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20pH-sensitive%20hydrogels" title=" smart pH-sensitive hydrogels"> smart pH-sensitive hydrogels</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogel%20micelle%20diameter" title=" hydrogel micelle diameter"> hydrogel micelle diameter</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesion%20tests" title=" adhesion tests"> adhesion tests</a> </p> <a href="https://publications.waset.org/abstracts/84736/spontaneous-generation-of-wrinkled-patterns-on-ph-sensitive-smart-hydrogel-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84736.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">206</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">100</span> Overcoming the Problems Affecting Drip Irrigation System through the Design of an Efficient Filtration and Flushing System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephen%20A.%20Akinlabi">Stephen A.

The use of drip irrigation system has been the most efficient system compared to the other types of irrigations systems because the drip irrigation helps to save water and increase the productivity of crops. But like any other system, it can be considered inefficient when the filters and the emitters get clogged while in operation. The efficiency of the entire system is reduced when the emitters are clogged and blocked. This consequently impact and affect the farm operations which may result in scarcity of farm products and increase the demand. This design work focuses on how to overcome some of the challenges affecting drip irrigation system through the design of an efficient filtration and flushing system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drip%20irrigation%20system" title="drip irrigation system">drip irrigation system</a>, <a href="https://publications.waset.org/abstracts/search?q=filters" title=" filters"> filters</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20texture" title=" soil texture"> soil texture</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20engineering%20design" title=" mechanical engineering design"> mechanical engineering design</a>, <a href="https://publications.waset.org/abstracts/search?q=analysis" title=" analysis"> analysis</a> </p> <a href="https://publications.waset.org/abstracts/5838/overcoming-the-problems-affecting-drip-irrigation-system-through-the-design-of-an-efficient-filtration-and-flushing-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5838.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">383</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> Relationship and Comorbidity Between Down Syndrome and Autism Spectrum Disorder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javiera%20Espinosa">Javiera Espinosa</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20L%C3%B3pez"> Patricia López</a>, <a href="https://publications.waset.org/abstracts/search?q=Noelia%20Santos"> Noelia Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Loro"> Nadia Loro</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Moraleda"> Esther Moraleda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there has been a notable increase in the number of investigations that establish that Down Syndrome and Autism Spectrum Disorder are diagnoses that can coexist together.

For juveniles, who are more susceptible to irreparable harm due to their underdeveloped psyches, the risks are exacerbated. Despite these risks, across the United States juvenile detainees are regularly held in isolation for prolonged periods of time. This essay will examine the broad impact of solitary confinement on juvenile detainees while giving particular focus to the story of Kalief Browder, a juvenile awaiting trial on Rikers Island in New York for a period of three years, nearly two years of which were spent in solitary confinement. Although sadly, his story is not uncommon, Kalief’s story offers a unique perspective in that it provides first-hand insight on the effects of solitary confinement on juveniles. It is our hope that by sharing his story, we will demand better detention practices and policies for juveniles under correctional control in the United States. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=criminal%20justice%20system" title="criminal justice system">criminal justice system</a>, <a href="https://publications.waset.org/abstracts/search?q=juveniles" title=" juveniles"> juveniles</a>, <a href="https://publications.waset.org/abstracts/search?q=Kalief%20browder" title=" Kalief browder"> Kalief browder</a>, <a href="https://publications.waset.org/abstracts/search?q=solitary%20confinement" title=" solitary confinement"> solitary confinement</a> </p> <a href="https://publications.waset.org/abstracts/46258/who-killed-kalief-examining-the-effects-of-solitary-confinement-on-juvenile-detainees-in-the-united-states" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46258.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">322</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">95</span> Characterising the Effects of Heat Treatment on 3CR12 and AISI 316 Stainless Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20T.%20Akinlabi">Esther T.

Heat treatment was conducted on the steel grades and cooled using two different media; air and water in order to study the effect of each medium on the evolving properties of the samples. The heat treated samples were characterized through the evolving microstructure and hardness. It was found that there was a significant grain size reduction in both the heat treated stainless steel specimens compared to the parent materials. The finer grain sizes were achieved as a result of impediment to growth of one phase by the other. The Vickers micro-hardness values of the heat treated samples were higher compared to the parent materials due to the fact that each of the steel grades had a proportion of martensitic structures in their microstructures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=austenite" title="austenite">austenite</a>, <a href="https://publications.waset.org/abstracts/search?q=ferrite" title=" ferrite"> ferrite</a>, <a href="https://publications.waset.org/abstracts/search?q=grain%20size" title=" grain size"> grain size</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=martensite" title=" martensite"> martensite</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure%20and%20stainless%20steel" title=" microstructure and stainless steel"> microstructure and stainless steel</a> </p> <a href="https://publications.waset.org/abstracts/5781/characterising-the-effects-of-heat-treatment-on-3cr12-and-aisi-316-stainless-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5781.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">269</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">94</span> Modeling and Analysis of Laser Sintering Process Scanning Time for Optimal Planning and Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agarana%20Michael%20C.">Agarana Michael C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinlabi%20Esther%20T."> Akinlabi Esther T.</a>, <a href="https://publications.waset.org/abstracts/search?q=Pule%20Kholopane"> Pule Kholopane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to sustain the advantages of an advanced manufacturing technique, such as laser sintering, minimization of total processing cost of the parts being produced is very important.

Material characterizations were conducted on a 6 mm thick plates of type-304 austenite stainless steel, welded by TIG welding process at two different welding currents of 150 A (Sample F3) and 170 A (Sample F4). The tensile strength and the elongation obtained from sample F4 weld were approximately 584 MPa and 19.3 %; which were higher than sample F3 weld. The average microhardness value of sample F4 weld was found to be 235.7 HV, while that of sample F3 weld was 233.4 HV respectively. Homogenous distribution of iron (Fe), chromium (Cr) and nickel (Ni) were observed at the welded joint of the two samples. The energy dispersive spectroscopy (EDS) analysis revealed that Fe, Cr, and Ni made up the composition formed in the weld zone. The optimum welding current of 170 A for TIG welding of type-304 austenite stainless steel can be recommended for high-tech industrial applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microhardness" title="microhardness">microhardness</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile" title=" tensile"> tensile</a>, <a href="https://publications.waset.org/abstracts/search?q=MIG%20welding" title=" MIG welding"> MIG welding</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile" title=" tensile"> tensile</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20stress%20TIG%20welding" title=" shear stress TIG welding"> shear stress TIG welding</a>, <a href="https://publications.waset.org/abstracts/search?q=TIG-MIG%20welding" title=" TIG-MIG welding"> TIG-MIG welding</a> </p> <a href="https://publications.waset.org/abstracts/104566/effect-of-welding-current-on-mechanical-properties-and-microstructure-of-tungsten-inert-gas-welding-of-type-304-austenite-stainless-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104566.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">194</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">92</span> Mathematical Knowledge a Prerequisite for Science Education Courses in Tertiary Institution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20Yemisi%20Akinjiola">Esther Yemisi Akinjiola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mathematics has been regarded as the backbone of science and technological development, without which no nation can achieve any sustainable growth and development. Mathematics is a useful tool to simplify science by quantification of phenomena; hence physics and chemistry cannot be done without Calculus and Statistics. Mathematics is used in physical science to calculate the measurement of objects and their characteristics, as well as to show the relationship between different functions and properties. Mathematics is the building block for everything in our daily lives, including the use of mobile devices, architecture design, ancient arts, engineering sports, and. among others. Therefore the study of Mathematics is made compulsory at primary, basic, and secondary school levels. Thus, this paper discusses the concepts of Mathematics, science, and their relationships. Also, it discusses Mathematics contents needed to study science-oriented courses such as physics education, chemistry education, and biology education in the tertiary institution. The paper concluded that without adequate knowledge of Mathematics, it will be difficult, if not impossible, for science education students to cope in their field of study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mathematical%20knowledge" title="mathematical knowledge">mathematical knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=prerequisite" title=" prerequisite"> prerequisite</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20education" title=" science education"> science education</a>, <a href="https://publications.waset.org/abstracts/search?q=tertiary%20institution" title=" tertiary institution"> tertiary institution</a> </p> <a href="https://publications.waset.org/abstracts/136738/mathematical-knowledge-a-prerequisite-for-science-education-courses-in-tertiary-institution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136738.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">91</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">91</span> Investigation of Polymer Composite for High Dose Dosimetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20Lorrayne%20%20M.%20Pereira">Esther Lorrayne M.

The samples were irradiated with a Co-60 source at constant dose rate (16.7 kGy/h), with doses ranging from 100 to 2750 kGy. The UV-Vis and FTIR spectrophotometry have been used to monitor the appearing of C=C conjugated bonds and radio-oxidation of carbon (C=O). FTIR spectrometry has that the absorbance intensities at 1715 cm⁻¹ and 1730 cm⁻¹ can be used for high dosimetry purposes for gamma doses ranging from 500 to 2750 kGy. In this range, it is possible to observe a linear relationship between Abs & Dose. Fading of signal was evaluated for one month and reproducibility in 2000 kGy dose. Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX) was used for evaluated the dispersion ZrO₂ and MWCNT in the matrix of the PVDF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer" title="polymer">polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20dose%20dosimetry" title=" high dose dosimetry"> high dose dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=PVDF%2FZrO%E2%82%82%2FMWCNT" title=" PVDF/ZrO₂/MWCNT"> PVDF/ZrO₂/MWCNT</a> </p> <a href="https://publications.waset.org/abstracts/65263/investigation-of-polymer-composite-for-high-dose-dosimetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65263.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">288</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">90</span> Elvis Improved Method for Solving Simultaneous Equations in Two Variables with Some Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elvis%20Adam%20Alhassan">Elvis Adam Alhassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kaiyu%20Tian"> Kaiyu Tian</a>, <a href="https://publications.waset.org/abstracts/search?q=Akos%20Konadu"> Akos Konadu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ernest%20Zamanah"> Ernest Zamanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Jackson%20Adjabui"> Michael Jackson Adjabui</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Justice%20Musah"> Ibrahim Justice Musah</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Agyeiwaa%20Owusu"> Esther Agyeiwaa Owusu</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20K.%20A.%20Agyeman"> Emmanuel K.

The Elvis improved method says; to make one variable in the first equation the subject; make the same variable in the second equation the subject; equate the results and simplify to obtain the value of the unknown variable; put the value of the variable found into one equation from the first or second steps and simplify for the remaining unknown variable. The difference between our Elvis improved method and the substitution method is that: with Elvis improved method, the same variable is made the subject in both equations, and the two resulting equations equated, unlike the substitution method where one variable is made the subject of only one equation and substituted into the other equation. After describing the Elvis improved method, findings from 100 secondary students and the views of 5 secondary tutors to demonstrate the effectiveness of the method are presented. The study's purpose is proved by hypothetical examples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=simultaneous%20equations" title="simultaneous equations">simultaneous equations</a>, <a href="https://publications.waset.org/abstracts/search?q=substitution%20method" title=" substitution method"> substitution method</a>, <a href="https://publications.waset.org/abstracts/search?q=elimination%20method" title=" elimination method"> elimination method</a>, <a href="https://publications.waset.org/abstracts/search?q=graphical%20method" title=" graphical method"> graphical method</a>, <a href="https://publications.waset.org/abstracts/search?q=Elvis%20improved%20method" title=" Elvis improved method"> Elvis improved method</a> </p> <a href="https://publications.waset.org/abstracts/165246/elvis-improved-method-for-solving-simultaneous-equations-in-two-variables-with-some-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165246.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">137</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">89</span> Nutritional Benefits of Soy: An Implication for Health Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mbadugha%20Esther%20Ifeoma">Mbadugha Esther Ifeoma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soybeans, like other legumes are rich in nutrients. However, the nutrient profile of soybeans differs in some important ways from most other legumes. Among other nutrients, soy is high in protein, carbohydrates, and fibers, is rich in vitamins, minerals and unsaturated fatty acids and is low in saturated fatty acids. Because of its high nutritional value, it has been rated to be equivalent to meats, eggs and milk. Soy has many health benefits including prevention of coronary heart disease, prevention of cancer growth, improvement of cognitive function, promotion of bone health, prevention of obesity, prevention of type II diabetes and promotion of growth of normal floras in the colon. Soybean consumption is also associated with some side effects which include allergy, flatulence and abdominal discomfort. Nurses/health care providers should therefore, educate clients on the precautionary measures to be taken in preparing soy food products in order to reduce to the barest minimum the side effects, while encouraging them to include soy as part of their daily meals for optimal health and vitality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20benefit" title="health benefit">health benefit</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20education" title=" health education"> health education</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20benefit" title=" nutritional benefit"> nutritional benefit</a>, <a href="https://publications.waset.org/abstracts/search?q=soybeans" title=" soybeans"> soybeans</a> </p> <a href="https://publications.waset.org/abstracts/23072/nutritional-benefits-of-soy-an-implication-for-health-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23072.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">490</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">88</span> Main Cause of Children's Deaths in Indigenous Wayuu Community from Department of La Guajira: A Research Developed through Data Mining Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaura%20Esther%20Solano%20N%C3%BA%C3%B1ez">Isaura Esther Solano Núñez</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Suarez"> David Suarez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this research is to discover what causes death in children of the Wayuu community, and deeply analyze those results in order to take corrective measures to properly control infant mortality. We consider important to determine the reasons that are producing early death in this specific type of population, since they are the most vulnerable to high risk environmental conditions. In this way, the government, through competent authorities, may develop prevention policies and the right measures to avoid an increase of this tragic fact. The methodology used to develop this investigation is data mining, which consists in gaining and examining large amounts of data to produce new and valuable information. Through this technique it has been possible to determine that the child population is dying mostly from malnutrition. In short, this technique has been very useful to develop this study; it has allowed us to transform large amounts of information into a conclusive and important statement, which has made it easier to take appropriate steps to resolve a particular situation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=malnutrition" title="malnutrition">malnutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a>, <a href="https://publications.waset.org/abstracts/search?q=descriptive" title=" descriptive"> descriptive</a>, <a href="https://publications.waset.org/abstracts/search?q=population" title=" population"> population</a>, <a href="https://publications.waset.org/abstracts/search?q=Wayuu" title=" Wayuu"> Wayuu</a>, <a href="https://publications.waset.org/abstracts/search?q=indigenous" title=" indigenous"> indigenous</a> </p> <a href="https://publications.waset.org/abstracts/86076/main-cause-of-childrens-deaths-in-indigenous-wayuu-community-from-department-of-la-guajira-a-research-developed-through-data-mining-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86076.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">159</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">87</span> An Experimental Study on the Effect of Heat Input on the Weld Efficiency of TIG-MIG Hybrid Welding of Type-304 Austenitic Stainless Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Ogundimu">Emmanuel Ogundimu</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Akinlabi"> Esther Akinlabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mutiu%20Erinosho"> Mutiu Erinosho</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Welding is described as the process of joining metals so that bonding can be created as a result of inter-atomic penetration. This study investigated the influence of heat input on the efficiency of the welded joints of 304 stainless steel. Three welds joint were made from two similar 304 stainless steel plates of thickness 6 mm. The tensile results obtained showed that the maximum average tensile strength of 672 MPa is possessed by the sample A1 with low heat input. It was discovered that the tensile strength, % elongation and weld joint efficiency decreased with the increase in heat input into the weld. The average % elongation for the entire samples ranged from 28.4% to 36.5%. Sample A1 had the highest joint efficiency of 94.5%. However, the optimum welding current of 190 for TIG- MIG hybrid welding of type-304 austenite stainless steel can be recommended for advanced technological applications such as aircraft manufacturing, nuclear industry, automobile industry, and processing industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microhardness" title="microhardness">microhardness</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile" title=" tensile"> tensile</a>, <a href="https://publications.waset.org/abstracts/search?q=MIG%20welding" title=" MIG welding"> MIG welding</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile" title=" tensile"> tensile</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20stress%20TIG%20welding" title=" shear stress TIG welding"> shear stress TIG welding</a>, <a href="https://publications.waset.org/abstracts/search?q=TIG-MIG%20welding" title=" TIG-MIG welding"> TIG-MIG welding</a> </p> <a href="https://publications.waset.org/abstracts/104563/an-experimental-study-on-the-effect-of-heat-input-on-the-weld-efficiency-of-tig-mig-hybrid-welding-of-type-304-austenitic-stainless-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104563.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">199</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">86</span> Summer STEM Camp for Elementary Students: A Conduit to Pre-Service Teacher Training to Learn How to Include a Makerspace for an Inclusive Classroom</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Gallup">Jennifer Gallup</a>, <a href="https://publications.waset.org/abstracts/search?q=Beverly%20Ray"> Beverly Ray</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Ntuli"> Esther Ntuli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many students such as students from linguistically or culturally diverse backgrounds and those with a disability remain chronically underrepresented in higher level science and mathematics disciplines as well as many hands-on-lab-based activities due to the need for remedial reading and mathematics instruction. Makerspace labs can be a conduit for supporting inclusive learning for these students through hands-on active learning strategies that support equitable access to STEM disciplines. Makerspace is a physical space where individuals gather to create, invent, innovate, and learn while using hands-on materials such as 2D and 3D printers, software programs, electronics, and other tools and supplies. Makerspaces are emerging across many P-12 settings; however, many teachers enter the field not prepared to harness the power inherent in a makerspace, especially for those with disabilities and differing needs. This paper offers suggestions on teaching pre-service teachers and practicing teachers how to incorporate a makerspace into their professional practice through guided instruction and hands-on practice.

The slight variations in the polymerization conditions produce important changes in the material composition and pattern structuration. The compounds were synthesized using three main components, i.e. an amphiphilic monomer, hydroxyethyl methacrylate (HEMA), a hydrophobic monomer, trifluoroethyl methacrylate (TFMA), and a hydrophilic crosslinking agent, poly(ethylene glycol) diacrylate (PEGDA). The first part of this study was related to the formation of wrinkled surfaces using only HEMA and PEGDA and varying the amount of water added in the reaction. The second part of this study involves the gradual insertion of TFMA into the hydrophilic reaction mixture. Interestingly, the manipulation of the chemical composition of this hydrogel affects both surface morphology and physicochemical characteristics of the patterns, inducing transitions from one particular type of structure (wrinkles or ripples) to different ones (creases, folds, and crumples). Contact angle measurements show that the insertion of TFMA produces a slight decrease in surface wettability of the samples, remaining however highly hydrophilic (contact angle below 45°). More interestingly, by using confocal Raman spectroscopy, important information about the wrinkle formation mechanism is obtained. The procedure involving two consecutive thermal and photopolymerization steps lead to a “pseudo” two-layer system. Thus, upon photopolymerization, the surface is crosslinked to a higher extent than the bulk and water evaporation drives the formation of wrinkled surfaces. Finally, cellular, and bacterial proliferation studies were performed to the samples, showing that the amount of TFMA included in each sample slightly affects the proliferation of both (bacteria and cells), but in the case of bacteria, the morphology of the sample also plays an important role, importantly reducing the bacterial proliferation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibiofouling%20properties" title="antibiofouling properties">antibiofouling properties</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobic%2Fhydrophilic%20balance" title=" hydrophobic/hydrophilic balance"> hydrophobic/hydrophilic balance</a>, <a href="https://publications.waset.org/abstracts/search?q=morphologic%20characterization" title=" morphologic characterization"> morphologic characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=wrinkled%20hydrogel%20patterns" title=" wrinkled hydrogel patterns"> wrinkled hydrogel patterns</a> </p> <a href="https://publications.waset.org/abstracts/84760/preliminary-studies-of-antibiofouling-properties-in-wrinkled-hydrogel-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84760.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">84</span> Delineation of the Geoelectric and Geovelocity Parameters in the Basement Complex of Northwestern Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20D.%20Dogara">M.

The variability of the lithology is consistently inconsistent. Hence, the need for a close range study, it is, in view of the above that, two geophysical techniques, the vertical electrical sounding employing the Schlumberger array and seismic refraction methods, were used to delineate the geoelectric and geovelocity parameters of the basement complex of northwestern Nigeria. A total area of 400,000 m² was covered with sixty geoelectric stations established and sixty sets of seismic refraction data collected using the forward and reverse method. From the interpretation of the resistivity data, it is suggestive that the area is underlain by not more than five geoelectric layers of varying thicknesses and resistivities when a maximum half electrode spread of 100m was used. The result of the interpreted seismic data revealed two geovelocity layers, with velocities ranging between 478m/s to 1666m/s for the first layer and 1166m/s to 7141m/s for the second layer. The results of the two techniques, suggests that the area of study has an undulating bedrock topography with geoeletric and geovelocity layers composed of weathered rock materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basement%20complex" title="basement complex">basement complex</a>, <a href="https://publications.waset.org/abstracts/search?q=delineation" title=" delineation"> delineation</a>, <a href="https://publications.waset.org/abstracts/search?q=geoelectric" title=" geoelectric"> geoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=geovelocity" title=" geovelocity"> geovelocity</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/118092/delineation-of-the-geoelectric-and-geovelocity-parameters-in-the-basement-complex-of-northwestern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118092.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">83</span> Recurrent Patterns of Netspeak among Selected Nigerians on WhatsApp Platform: A Quest for Standardisation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lily%20Chimuanya">Lily Chimuanya</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Ajiboye"> Esther Ajiboye</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Uba"> Emmanuel Uba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the consequences of online communication is the birth of new orthography genres characterised by novel conventions of abbreviation and acronyms usually referred to as Netspeak. Netspeak, also known as internet slang, is a style of writing mainly used in online communication to limit the length of text characters and to save time. The aim of this study is to evaluate how second language users of the English language have internalised this new convention of writing; identify the recurrent patterns of Netspeak; and assess the consistency of the use of the identified patterns in relation to their meanings. The study is corpus-based, and data drawn from WhatsApp chart pages of selected groups of Nigerian English speakers show a large occurrence of inconsistencies in the patterns of Netspeak and their meanings. The study argues that rather than emphasise the negative impact of Netspeak on the communicative competence of second language users, studies should focus on suggesting models as yardsticks for standardising the usage of Netspeak and indeed all other emerging language conventions resulting from online communication. This stance stems from the inevitable global language transformation that is eminent with the coming of age of information technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abbreviation" title="abbreviation">abbreviation</a>, <a href="https://publications.waset.org/abstracts/search?q=acronyms" title=" acronyms"> acronyms</a>, <a href="https://publications.waset.org/abstracts/search?q=Netspeak" title=" Netspeak"> Netspeak</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20communication" title=" online communication"> online communication</a>, <a href="https://publications.waset.org/abstracts/search?q=standardisation" title=" standardisation"> standardisation</a> </p> <a href="https://publications.waset.org/abstracts/70670/recurrent-patterns-of-netspeak-among-selected-nigerians-on-whatsapp-platform-a-quest-for-standardisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70670.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">391</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">82</span> Impact of Culture and Religion on Disability and the Health Care Seeking Practices of the Shona People</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mafunda%20Esther">Mafunda Esther</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper seeks to find out and document the impact of culture and religion on disability, specifically language impairment and health care seeking practices of the Shona people.

The other objective of the paper is to describe how language impairment is presented and understood by people living in a Zimbabwean rural area. The research is qualitative interpretive phenomenological research, and it utilizes the case study approach using semi structured interviews and focus group discussions. Results from the research established that religious and cultural beliefs determine how the Shona people view disability, and this guides their health care seeking practices. The research is important since communication disorders occur in populations worldwide though they are not always recognized as such.

The proposed feature extraction method take advantage of the knowledge related to which parts of the face reflects the highest deformations, so we selected 4 specific facial regions at which the appearance descriptor were applied. The most common used approaches for feature extraction are the holistic and the local strategies. In this work we present the results of using a local appearance approach estimating the correlation coefficient to the 4 corresponding landmark-localized facial templates of the expression face related to the neutral face. The results let us to probe how the proposed motion estimation scheme based on the local appearance correlation computation can simply and intuitively measure the motion parameters for some of the most relevant facial regions and how these parameters can be used to recognize facial expressions automatically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=facial%20expression%20recognition%20system" title="facial expression recognition system">facial expression recognition system</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20extraction" title=" feature extraction"> feature extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=local-appearance%20method" title=" local-appearance method"> local-appearance method</a>, <a href="https://publications.waset.org/abstracts/search?q=motion-based%20approach" title=" motion-based approach"> motion-based approach</a> </p> <a href="https://publications.waset.org/abstracts/27632/classifying-facial-expressions-based-on-a-motion-local-appearance-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27632.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">413</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">80</span> Phytochemicals from Enantia Chlorantha Stem Bark Inhibits the Activity ?-Amylase and ?-Glucosidase: Molecular Docking Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hammed%20Tanimowo%20Aiyelabegan">Hammed Tanimowo Aiyelabegan</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluchukwu%20Franklin%20Aladi"> Oluchukwu Franklin Aladi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mutiu%20Adewumi%20Alabi"> Mutiu Adewumi Alabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Raliat%20Abimbola%20Aladodo"> Raliat Abimbola Aladodo</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Oladipupo%20Ajani"> Emmanuel Oladipupo Ajani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulganiyu%20Giwa"> Abdulganiyu Giwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Esther%20Owolabi"> Esther Owolabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study aimed to evaluate the inhibitory activities of ligands from Enantia chlorantha stem bark on α-amylase and α-glucosidase. In silico pharmacokinetic properties and docking scores were employed to analyse the inhibition using SwissADME and Autodock4.2, respectively. Results revealed that drug-likeness, pharmacokinetics and bioavailability radar of all the ligands except jatrorrhizine and acarbose falls within the radar according to the Lipinski rule of 5. The binding energies of the protein-ligand interactions also show that the ligand fits into the active site. The results obtained from this study show that the chemical constituents from Enantia chlorantha stem bark may bring about positive physiological changes in a patient suffering from diabetes mellitus. Further in vitro studies on diabetes cell lines and in vivo studies on the animal may validate these compounds for diabetes treatment. These phytoconstituents could help in the development of novel anti-diabetic molecules. <p class="card-text"><strong>Keywords:</strong> <a
