non-government organizations in time and space express the quantitative and qualitative features of different fields of various reforms implemented in different countries. The main objective of our research is to develop new methodology that we will use to create integral index based on many indexes and that will include many areas of reforms. To achieve our aim we have used econometric methods (regression model for panel data method). The basis of our methodology is the development of the new integral index based on quantitative assessment of the change of two main parameters: the score of the countries by different indexes and the change of the ranks of countries for following two periods of time. As a result of the usage of methods for analyzes we have defined the indexes that are used to create the new integral index and the scales for each of them. Analyzing quantitatively and qualitatively analysis through the integral index for more than 100 countries for 2009-2014, we have defined comparative efficiency that helps to conclude in which directions countries have implemented reforms more effectively compared to others and in which direction reforms have implemented less efficiently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development" title="development">development</a>, <a href="https://publications.waset.org/abstracts/search?q=rank" title=" rank"> rank</a>, <a href="https://publications.waset.org/abstracts/search?q=reforms" title=" reforms"> reforms</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative" title=" comparative"> comparative</a>, <a href="https://publications.waset.org/abstracts/search?q=index" title=" index"> index</a>, <a href="https://publications.waset.org/abstracts/search?q=economic" title=" economic"> economic</a>, <a href="https://publications.waset.org/abstracts/search?q=corruption" title=" corruption"> corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=social" title=" social"> social</a>, <a href="https://publications.waset.org/abstracts/search?q=program" title=" program"> program</a> </p> <a href="https://publications.waset.org/abstracts/29322/the-assessment-of-the-comparative-efficiency-of-reforms-through-the-integral-index-of-transformation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29322.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">326</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">47</span> Preliminary Design Considerations for Achieving Stabilized Orbit, Telemetary, Command, and Ranging for HTS Communication Satellite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Isa%20Ali%20%28Pantami%29">Ibrahim Isa Ali (Pantami)</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdu%20Jaafaru%20Bambale"> Abdu Jaafaru Bambale</a>, <a href="https://publications.waset.org/abstracts/search?q=Abimbola%20Alale"> Abimbola Alale</a>, <a href="https://publications.waset.org/abstracts/search?q=Danjuma%20Ibrahim%20%20Ndihgihdah"> Danjuma Ibrahim Ndihgihdah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkali"> Muhammad Alkali</a>, <a href="https://publications.waset.org/abstracts/search?q=Adamu%20Idris%20Umar"> Adamu Idris Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Olufunmilayo%20Abodunrin"> Samson Olufunmilayo Abodunrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Dokko%20Zubairu"> Muhammad Dokko Zubairu</a>, <a href="https://publications.waset.org/abstracts/search?q=Moshood%20Kareem"> Moshood Kareem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the consideration and trade-offs used for the implementation of robust systems for orbit stability; Telemetry, Command and Ranging (TC& R) for Nigcomsat-1R and applicability for planned NigComSat-2 satellites.

In this work we tried to prepare a ceramic electrolyte (Li6.5 La2.5 Ba0.5 Nb Zr O12(LLBNZO)) and sintered the pallets of as-prepared material at elevated temperature like 1050, 1100, 1150 and 1200 °C. The objective to carry out this research was to observe the effect of temperature on porosity, density and transport properties of materials. Preliminary results suggest that the material sintered at higher temperature could show enhanced performance in terms of fast ionic transport. This enhancement in performance can be attributed to low porosity of materials which is result of high temperature sintering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20battery" title="solid state battery">solid state battery</a>, <a href="https://publications.waset.org/abstracts/search?q=electrolyte" title=" electrolyte"> electrolyte</a>, <a href="https://publications.waset.org/abstracts/search?q=garnet%20structures" title=" garnet structures"> garnet structures</a>, <a href="https://publications.waset.org/abstracts/search?q=Li-ion%20battery" title=" Li-ion battery"> Li-ion battery</a> </p> <a href="https://publications.waset.org/abstracts/42973/effect-of-sintering-temperature-on-transport-properties-of-garnet-type-solid-state-electrolytes-for-energy-storage-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42973.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">274</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> The Roles of Pay Satisfaction and Intent to Leave on Counterproductive Work Behavior among Non-Academic University Employees </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Musbau%20Lawal">Abiodun Musbau Lawal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunday%20Samson%20Babalola"> Sunday Samson Babalola</a>, <a href="https://publications.waset.org/abstracts/search?q=Uzor%20Friday%20Ordu"> Uzor Friday Ordu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Issue of employees counterproductive work behavior in government owned organization in emerging economies has continued to be a major concern. This study investigated the factors of pay satisfaction, intent to leave and age as predictors of counterproductive work behavior among non-academic employee in a Nigerian federal government owned university. A sample of 200 non-academic employees completed questionnaires. Hierarchical multiple regression was conducted to determine the contribution of each of the predictor variables on the criterion variable on counterproductive work behavior. Results indicate that age of participants (β = -.18; p < .05) significantly independently predicted CWB by accounting for 3% of the explained variance. Addition of pay satisfaction (β = -.14; p < .05) significantly accounted for 5% of the explained variance, while intent to leave (β = -.17; p < .05) further resulted in 8% of the explained variance in counterproductive work behavior. The importance of these findings with regards to reduction in counterproductive work behavior is highlighted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=counterproductive" title="counterproductive">counterproductive</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20behaviour" title=" work behaviour"> work behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=pay%20satisfaction" title=" pay satisfaction"> pay satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=intent%20to%20leave" title=" intent to leave"> intent to leave</a> </p> <a href="https://publications.waset.org/abstracts/57766/the-roles-of-pay-satisfaction-and-intent-to-leave-on-counterproductive-work-behavior-among-non-academic-university-employees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57766.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">384</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Nigcomsat-1r and Planned HTS Communication Satellite Critical Pillars for Nigeria’s National Digital Economy Policy and Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Isa%20Ali%20%28Pantami%29">Ibrahim Isa Ali (Pantami)</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdu%20Jaafaru%20Bambale"> Abdu Jaafaru Bambale</a>, <a href="https://publications.waset.org/abstracts/search?q=Abimbola%20Alale"> Abimbola Alale</a>, <a href="https://publications.waset.org/abstracts/search?q=Danjuma%20Ibrahim%20Ndihgihdah"> Danjuma Ibrahim Ndihgihdah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Alkali"> Muhammad Alkali</a>, <a href="https://publications.waset.org/abstracts/search?q=Adamu%20Idris%20Umar"> Adamu Idris Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Moshood%20Kareem"> Moshood Kareem</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Olufunmilayo%20Abodunrin"> Samson Olufunmilayo Abodunrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Dokko%20Zubairu"> Muhammad Dokko Zubairu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The National Digital Economy Policy and Strategy, NDEPS document developed by Nigeria’s Federal Ministry of Communications & Digital Economy (FMoCDE) is anchored on 8 pillars for the acceleration of the National Digital Economy for a Digital Nigeria.

Therefore, the present work developed a quantitative relationship between diesel consumption and vehicle age, annual use and cost of maintenance of the different makes of articulated vehicles. The vehicles selected for the study were FIAT 682 T3, IVECO 19036 and M.A.N. Diesel 19.240. The operating parameters for 90 vehicles of different age groups were recorded. Multiple regression models for diesel consumption of articulated vehicles of different makes were developed. From the analysis of results, it can be concluded that as the age of the vehicles increases, the diesel consumption increases. Also, as the diesel consumption increases, the cost of maintenance increases and there is a subsequent decrease in annual use. Moreover, FIAT 682 T3 and IVECO 19036 should be replaced at 7 years of age while M.A.N diesel should be replaced at 8 years of age. These are the ages where the diesel consumption becomes abnormal and uneconomical and they are points of optimal overhaul. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vehicle" title="vehicle">vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=overhaul" title=" overhaul"> overhaul</a>, <a href="https://publications.waset.org/abstracts/search?q=age" title=" age"> age</a>, <a href="https://publications.waset.org/abstracts/search?q=uneconomical" title=" uneconomical"> uneconomical</a>, <a href="https://publications.waset.org/abstracts/search?q=diesel" title=" diesel"> diesel</a>, <a href="https://publications.waset.org/abstracts/search?q=consumption" title=" consumption"> consumption</a> </p> <a href="https://publications.waset.org/abstracts/76695/mathematical-modelling-for-diesel-consumption-of-articulated-vehicle-used-in-oyo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76695.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">251</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">42</span> Laboratory Testing Regime for Quantifying Soil Collapsibility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anne%20C.%20Okwedadi">Anne C.

This loss of volume in soil as seen in foundation failures has caused millions of dollars’ worth of damages to public facilities and infrastructure and so has an adverse effect on the society and people. Despite these consequences and the several studies that are available, more research is still required in the study of soil collapsibility. Discerning the pedogenesis (formation) of soils and investigating the combined effects of the different geological soil properties is key to elucidating and quantifying soils collapsibility. This study presents a novel laboratory testing regime that would be undertaken on soil samples where the effects of soil type, compactive variables (moisture content, density, void ratio, degree of saturation) and loading are analyzed. It is anticipated that results obtained would be useful in mapping the trend of the combined effect thus the basis for evaluating soil collapsibility or collapse potentials encountered in construction with volume loss problems attributed to collapse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collapsible%20soil" title="collapsible soil">collapsible soil</a>, <a href="https://publications.waset.org/abstracts/search?q=geomorphological%20process" title=" geomorphological process"> geomorphological process</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20collapsibility%20properties" title=" soil collapsibility properties"> soil collapsibility properties</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20test" title=" soil test"> soil test</a> </p> <a href="https://publications.waset.org/abstracts/11788/laboratory-testing-regime-for-quantifying-soil-collapsibility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11788.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">471</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> A Sequential Approach for Random-Effects Meta-Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20Henry%20Dogo">Samson Henry Dogo</a>, <a href="https://publications.waset.org/abstracts/search?q=Allan%20Clark"> Allan Clark</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Kulinskaya"> Elena Kulinskaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective in meta-analysis is to combine results from several independent studies in order to create generalization and provide evidence based for decision making. But recent studies show that the magnitude of effect size estimates reported in many areas of research finding changed with year publication and this can impair the results and conclusions of meta-analysis. A number of sequential methods have been proposed for monitoring the effect size estimates in meta-analysis. However they are based on statistical theory applicable to fixed effect model (FEM). For random-effects model (REM), the analysis incorporates the heterogeneity variance, tau-squared and its estimation create complications. In this paper proposed the use of Gombay and Serbian (2005) truncated CUSUM-type test with asymptotically valid critical values for sequential monitoring of REM. Simulation results show that the test does not control the Type I error well, and is not recommended. Further work required to derive an appropriate test in this important area of application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=meta-analysis" title="meta-analysis">meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=random-effects%20model" title=" random-effects model"> random-effects model</a>, <a href="https://publications.waset.org/abstracts/search?q=sequential%20test" title=" sequential test"> sequential test</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20changes%20in%20effect%20sizes" title=" temporal changes in effect sizes"> temporal changes in effect sizes</a> </p> <a href="https://publications.waset.org/abstracts/20044/a-sequential-approach-for-random-effects-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20044.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">467</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Water and Sanitation Challenges: A Case of King Sabatha Dalindyebo Municipality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masibulele%20Fiko">Masibulele Fiko</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Balkara"> Sanjay Balkara</a>, <a href="https://publications.waset.org/abstracts/search?q=Beauty%20Makiwane"> Beauty Makiwane</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Asoba"> Samson Asoba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several municipalities in the Eastern Cape Province of South Africa suffer from severe infrastructure dilapidation and a backlog in repairs and replacement. This scourge is most critical in black dominated areas, such as the rural communities and townships. Several critical service delivery activities have been impaired consequent to the deteriorating facilities and a lot of human endeavors impacted adversely. As such, this study investigated the water and sanitation challenges in King Sabatha Dalindyebo municipality, Eastern Cape Province of South Africa. Questionnaires were distributed to the communities and interviews were conducted with the communities’ leaders. The Participants mentioned that their main sources of water supply were a dam, streams, springs and wells; and the distances to the water sources were thought to be too long and women were often attacked and sometimes raped. South African local authorities are facing problems of insufficient funds to meet their daily operations. The municipality should provide street taps. The alternative way for government to supply financial aid to local authorities is to introduce the private sector in the service rendering process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communities" title="communities">communities</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation" title=" sanitation"> sanitation</a>, <a href="https://publications.waset.org/abstracts/search?q=managers" title=" managers"> managers</a>, <a href="https://publications.waset.org/abstracts/search?q=municipality" title=" municipality"> municipality</a> </p> <a href="https://publications.waset.org/abstracts/124327/water-and-sanitation-challenges-a-case-of-king-sabatha-dalindyebo-municipality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124327.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">124</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">39</span> Organization Development’s Role in Environmental, Social and Governance (ESG) Sustainability in the Private Organizations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Karmela%20Palma%20Samson">Karmela Palma Samson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, there has been a growing interest in the implementation of Environmental, Social, and Governance (ESG) frameworks in private organizations. The COVID-19 pandemic and increasing global environmental concerns have further highlighted the importance of ESG practices in businesses. To be effective, the development and sustainability of ESG implementation require specific organizational functions. One such function is Organization Development (OD). This study aims to identify the roles of OD in the development, monitoring, and evaluation of ESG in private organizations. The role of OD in sustaining ESG implementation in private organizations was analyzed in this study. Qualitative research was conducted, which included interviews with OD practitioners to understand their role and challenges in maintaining ESG programs and initiatives. The study found that OD practitioners have low participation in managing ESG programs, initiatives, and indicators. However, the study also revealed that the OD function is crucial for the development, monitoring, and evaluation of ESG implementation in private organizations. In essence, the study highlights the importance of the OD function in ensuring the success of ESG implementation in private organizations. With their expertise in organizational development, OD practitioners can contribute significantly to the development, implementation, and evaluation of ESG initiatives. Therefore, private organizations should involve their OD departments in ESG implementation to ensure that they are sustainable, effective, and aligned with their organizational goals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ESG" title="ESG">ESG</a>, <a href="https://publications.waset.org/abstracts/search?q=organization%20development" title=" organization development"> organization development</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20sector" title=" private sector"> private sector</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/170344/organization-developments-role-in-environmental-social-and-governance-esg-sustainability-in-the-private-organizations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170344.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">89</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">38</span> Experimental Investigation to Find Transition Temperature of VG 30 Binder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Latha">D.

Since the binders are visco-elastic material which is having the mechanical properties of binder transition from visco-elastic solid to visco-elastic fluid. In this paper, two different protocols were used to measure the viscosity property of binder using a Brookfield Viscometer and there is a need to find the appropriate mixing and compaction temperatures of various types of binders which can result in complete aggregate coating and adequate field density of HMA mixtures. The aim of this work is to find the transition temperature from Non-Newtonian behavior to Newtonian behavior of the binder by adopting a steady shear protocol and the shear rate ramp protocol. The transition from non-Newtonian to Newtonian can occur through an increase of temperature and shear of the material. The test has been conducted for unmodified binder VG 30. The transition temperature was found in the unmodified binder VG is 120oC. So the application of both modified binder and unmodified binder in the pavement construction needs to be studied properly by considering temperature and traffic loading factors of the respective project site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unmodified%20and%20modified%20binders" title="unmodified and modified binders">unmodified and modified binders</a>, <a href="https://publications.waset.org/abstracts/search?q=Brookfield%20viscometer" title=" Brookfield viscometer"> Brookfield viscometer</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20temperature" title=" transition temperature"> transition temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=steady%20shear%20and%20shear%20rate%20protocol" title=" steady shear and shear rate protocol"> steady shear and shear rate protocol</a> </p> <a href="https://publications.waset.org/abstracts/40594/experimental-investigation-to-find-transition-temperature-of-vg-30-binder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40594.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">215</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> Antibiotic Potential of Bioactive Compounds from a Marine Streptomyces Isolated from South Pacific Sediments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ilaisa%20Kacivakanadina">Ilaisa Kacivakanadina</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Viulu"> Samson Viulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Brad%20Carte"> Brad Carte</a>, <a href="https://publications.waset.org/abstracts/search?q=Katy%20Soapi"> Katy Soapi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two bioactive compounds namely Vulgamycin (also known as enterocin A) and 5-deoxyenterocin were purified from a marine bacterial strain 1903. Strain 1903 was isolated from marine sediments collected from the Solomon Islands. Morphological features of strain 1903 showed that it belongs to the genus Streptomyces. The two secondary metabolites were extracted using EtOAc and purified by chromatographic methods using EtOAc and hexane solvents. Mass spectrum and NMR data of pure compounds were used to elucidate the chemical structures. In this study, results showed that both compounds were strongly active against Wild Type Staphylococcus aureus (WTSA) (MIC < 1 µg/mL) and in Brine shrimp assays (BSA) (MIC < 1 µg/mL). 5-deoxyenterocin was also active against Rifamycin resistant Staphylococcus aureus (RRSA) (MIC, 250 µg/mL) while vulgamycin showed bioactivity against Methicillin resistant Staphylococcus aureus (MRSA) (MIC 250 µg/mL). To the best of our knowledge, this is the first study that showed the bio-activity of 5-deoxyenterocin. This is also the first time that Vulgamycin has been reported to be active in a BSA. There has not been any mechanism of action studies for these two compounds against pathogens. This warrants further studies on their mechanism of action against microbial pathogens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=5-deoxyenterocin" title="5-deoxyenterocin">5-deoxyenterocin</a>, <a href="https://publications.waset.org/abstracts/search?q=bioactivity" title=" bioactivity"> bioactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=brine%20shrimp%20assay%20%28BSA%29" title=" brine shrimp assay (BSA)"> brine shrimp assay (BSA)</a>, <a href="https://publications.waset.org/abstracts/search?q=vulgamycin" title=" vulgamycin"> vulgamycin</a> </p> <a href="https://publications.waset.org/abstracts/79050/antibiotic-potential-of-bioactive-compounds-from-a-marine-streptomyces-isolated-from-south-pacific-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79050.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">189</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> Gender Influence in Yoruba Festivals: A Case Study of Agbaasin Festival in Isanlu-Isin, Kwara State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alice%20Abiodun%20Atolagbe">Alice Abiodun Atolagbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20Abiodun%20Atolagbe"> Samson Abiodun Atolagbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> All over the world and in the history of mankind, festivals have evolved to celebrate one thing or the other. The Yoruba people are no exemptions and they have several festivals which they celebrate at different times, for different reasons and in different communities. Because mankind is mainly of male and female, most of the festivals involve the two sexes, though different roles are usually assigned. In this paper, the writers examine the influence of gender in Yoruba festival using ‘Agbaasin’ festival in Isanlu-Isin, Kwara State of Nigeria as a case study. A research was conducted by visiting the priests, worshipers, and shrine of ‘Agbaasin’ during which interviews were conducted, documented, and analyzed. It was, thereafter, discovered that men dominated the process of celebrating the ‘Agbaasin’ festival even to the extent of cooking by themselves. The paper recommends that women should be more involved in political and communal activities, government should encourage and sponsor researches on gender issues and that, authors of books and writers of plays should create some fora to encourage women empowerment among the Yoruba people. It is hoped that this paper would contribute to the pool of literature available on gender issues among the Yoruba people of Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoruba" title=" Yoruba"> Yoruba</a>, <a href="https://publications.waset.org/abstracts/search?q=festival" title=" festival"> festival</a>, <a href="https://publications.waset.org/abstracts/search?q=Agbaasin" title=" Agbaasin"> Agbaasin</a>, <a href="https://publications.waset.org/abstracts/search?q=Isanlu-Isin" title=" Isanlu-Isin"> Isanlu-Isin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kwara%20State" title=" Kwara State"> Kwara State</a> </p> <a href="https://publications.waset.org/abstracts/49527/gender-influence-in-yoruba-festivals-a-case-study-of-agbaasin-festival-in-isanlu-isin-kwara-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49527.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">321</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">35</span> Change in Value System: The Way Forward for Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awe%20Ayodeji%20Samson">Awe Ayodeji Samson</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeuja%20Yetunde%20Omowunmi"> Adeuja Yetunde Omowunmi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corruption is a ‘monster’ that can consume a whole nation, continent and even the world if it is not destroyed while it is still immature; It grows in the mind of the people, takes over their thinking and guides their decision-making process. Corruption snowballs into socio-economic catastrophe that might be difficult to deal with. Corruption which is a disease of the mind can be alleviated in Africa and the world at large by transforming a Corruption-Prone Mind to a Corruption-Immune Mind and to achieve this, we have to change our value system because the use of anti-graft agencies alone is not enough. Therefore, we have to fight corruption from the inside and the outside. Value System is the principle of right and wrong that are accepted by an individual or a social group; the reviewing and reordering of our value system is the solution to the problem of corruption as proposed by this research because the African society has become a ‘Money and Power Driven Society’ where the ‘I am worth concept’ which is a problematic concept has created an ‘Aggressive Society’ with grasping and money-grabbing individuals. We place more priority on money and the display of opulence. Hence, this has led to a ‘Triangular Society’ where minority is lavishing in plenty and majority is gasping for little. The get rich quick syndrome, the ethnicity syndrome, weakened educational system are signs of the prevalence of corruption in Africa This research has analyzed role and impact of the change in our value system in the fight against corruption in Africa and has therefore proposed the change in our value system as the way forward in the fight against corruption in Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corruption-prone%20mind" title="corruption-prone mind">corruption-prone mind</a>, <a href="https://publications.waset.org/abstracts/search?q=corruption-immune%20mind" title=" corruption-immune mind"> corruption-immune mind</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular%20society" title=" triangular society"> triangular society</a>, <a href="https://publications.waset.org/abstracts/search?q=aggressive%20society" title=" aggressive society"> aggressive society</a>, <a href="https://publications.waset.org/abstracts/search?q=money%20and%20power-driven%20society" title=" money and power-driven society"> money and power-driven society</a> </p> <a href="https://publications.waset.org/abstracts/48565/change-in-value-system-the-way-forward-for-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48565.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">313</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">34</span> Histological Evaluation of the Neuroprotective Roles of Trans Cinnamaldehyde against High Fat Diet and Streptozotozin Induced Neurodegeneration in Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20Ehindero">Samson Ehindero</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwole%20Akinola"> Oluwole Akinola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Substantial evidence has shown an association between type 2 diabetes (T2D) and cognitive decline, Trans Cinnamaldehyde (TCA) has been shown to have many potent pharmacological properties. In this present study, we are currently investigating the effects of TCA on type II diabetes-induced neurodegeneration. Neurodegeneration was induced in forty (40) adult wistar rats using high fat diet (HFD) for 4 months followed by low dose of streptozotocin (STZ) (40 mg/kg, i.p.) administration. TCA was administered orally for 30 days at the doses of 40mg/kg and 60mg/kg body weight. Animals were randomized and divided into following groups; A- control group, B- diabetic group, C- TCA (high dose), D- diabetic + TCA (high dose), E- diabetic + TCA (high dose) with high fat diet, F- TCA Low dose, G- diabetic + TCA (low dose) and H- diabetic + TCA (low dose) with high fat diet. Animals were subjected to behavioral tests followed by histological studies of the hippocampus. Demented rats showed impaired behavior in Y- Maze test compared to treated and control groups. Trans Cinnamaldehyde restores the histo architecture of the hippocampus of demented rats. This present study demonstrates that treatment with trans- cinnamaldehyde improves behavioral deficits, restores cellular histo architecture in rat models of neurodegeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurodegeneration" title="neurodegeneration">neurodegeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=trans%20cinnamaldehyde" title=" trans cinnamaldehyde"> trans cinnamaldehyde</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20fat%20diet" title=" high fat diet"> high fat diet</a>, <a href="https://publications.waset.org/abstracts/search?q=streptozotocin" title=" streptozotocin "> streptozotocin </a> </p> <a href="https://publications.waset.org/abstracts/131178/histological-evaluation-of-the-neuroprotective-roles-of-trans-cinnamaldehyde-against-high-fat-diet-and-streptozotozin-induced-neurodegeneration-in-wistar-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131178.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">184</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">33</span> Design and Modelling of Ge/GaAs Hetero-structure Bipolar Transistor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20Mil%27shtein">Samson Mil'shtein</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhawal%20N.%20Asthana"> Dhawal N.

High diffusivity of carriers in GaAs base was major motivation of current design. We avoided grading of the base which is common in heterojunction bipolar transistors, in order to keep the electron diffusivity as high as possible. The electrons injected into the 0.25µm thick p-type GaAs base with not very high doping (1017cm-3). The designed HBT enables cut off frequency on the order of 150GHz. The Ge/GaAs heterojunctions presented in our paper have proved to work better than comparable HBTs having GaAs bases and emitter/collector junctions made, for example, of AlGaAs/GaAs or other III-V compound semiconductors. The difference in lattice constants between Ge and GaAs is less than 2%. Therefore, there is no need of transition layers between Ge emitter and GaAs base. Significant difference in energy gap of these two materials presents new scope for improving performance of the emitter. With the complete structure being modelled and simulated using TCAD SILVACO, the collector/ emitter offset voltage of the device has been limited to a reasonable value of 63 millivolts by the dint of low energy band gap value associated with Ge emitter. The efficiency of the emitter in our HBT is 86%. Use of Germanium in the emitter and collector regions presents new opportunities for integration of this vertical device structure into silicon substrate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Germanium" title="Germanium">Germanium</a>, <a href="https://publications.waset.org/abstracts/search?q=Gallium%20Arsenide" title=" Gallium Arsenide"> Gallium Arsenide</a>, <a href="https://publications.waset.org/abstracts/search?q=heterojunction%20bipolar%20transistor" title=" heterojunction bipolar transistor"> heterojunction bipolar transistor</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20cut-off%20frequency" title=" high cut-off frequency"> high cut-off frequency</a> </p> <a href="https://publications.waset.org/abstracts/139611/design-and-modelling-of-gegaas-hetero-structure-bipolar-transistor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139611.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">420</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> Iris Feature Extraction and Recognition Based on Two-Dimensional Gabor Wavelength Transform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bamidele%20Samson%20Alobalorun">Bamidele Samson Alobalorun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ifedotun%20Roseline%20Idowu"> Ifedotun Roseline Idowu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biometrics technologies apply the human body parts for their unique and reliable identification based on physiological traits. The iris recognition system is a biometric–based method for identification. The human iris has some discriminating characteristics which provide efficiency to the method. In order to achieve this efficiency, there is a need for feature extraction of the distinct features from the human iris in order to generate accurate authentication of persons. In this study, an approach for an iris recognition system using 2D Gabor for feature extraction is applied to iris templates. The 2D Gabor filter formulated the patterns that were used for training and equally sent to the hamming distance matching technique for recognition. A comparison of results is presented using two iris image subjects of different matching indices of 1,2,3,4,5 filter based on the CASIA iris image database. By comparing the two subject results, the actual computational time of the developed models, which is measured in terms of training and average testing time in processing the hamming distance classifier, is found with best recognition accuracy of 96.11% after capturing the iris localization or segmentation using the Daughman’s Integro-differential, the normalization is confined to the Daugman’s rubber sheet model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daugman%20rubber%20sheet" title="Daugman rubber sheet">Daugman rubber sheet</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=Hamming%20distance" title=" Hamming distance"> Hamming distance</a>, <a href="https://publications.waset.org/abstracts/search?q=iris%20recognition%20system" title=" iris recognition system"> iris recognition system</a>, <a href="https://publications.waset.org/abstracts/search?q=2D%20Gabor%20wavelet%20transform" title=" 2D Gabor wavelet transform"> 2D Gabor wavelet transform</a> </p> <a href="https://publications.waset.org/abstracts/170345/iris-feature-extraction-and-recognition-based-on-two-dimensional-gabor-wavelength-transform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170345.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">65</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> Residents Awareness and Willingness to Offer Homestay Accommodation to Tourists at a Listed World Heritage Site: Idanre Hills, Ondo State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arowosafe%20Folusade%20Catherine">Arowosafe Folusade Catherine</a>, <a href="https://publications.waset.org/abstracts/search?q=Arowosafe%20Olubunmi"> Arowosafe Olubunmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aina%20Samson"> Aina Samson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In many countries, tourism has been portrayed as a contributor to small-scale enterprises, contributing to improved standards of living, a catalyst for community development, and poverty alleviation.

Data collected were subjected to descriptive and inferential statistical analysis, and results were presented using frequency and percentage tables. Results: Findings revealed that the majority of the residents were above 60 years (47.3%), with 33% of them aware of the concept of homestay accommodation, and 32% had primary education. The majority were self-employed (43.3%), earning less than ₦30,000 per month; it also revealed that 80.7% of the residents owned at least one house and had adequate water supply facility (100%) and electricity (99.3%). Some constraints observed revealed that safety for the host family (mean 4.81) was ranked high as a possible deterrent to providing homestay accommodation to strangers. Results revealed a correlation between the resident’s awareness and willingness to provide homestay accommodation services (r.0.05, p<0.05). This study recommends that sensitization programs to create awareness of the potential benefits of homestay accommodation in the host communities of Idanre Hills should be carried out by the relevant stakeholders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accommodation" title="accommodation">accommodation</a>, <a href="https://publications.waset.org/abstracts/search?q=benefits" title=" benefits"> benefits</a>, <a href="https://publications.waset.org/abstracts/search?q=homestay" title=" homestay"> homestay</a>, <a href="https://publications.waset.org/abstracts/search?q=Idanre%20Hills" title=" Idanre Hills"> Idanre Hills</a> </p> <a href="https://publications.waset.org/abstracts/167034/residents-awareness-and-willingness-to-offer-homestay-accommodation-to-tourists-at-a-listed-world-heritage-site-idanre-hills-ondo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167034.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">69</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">30</span> A Contrastive Study of Affixation in Ipe and Yoruba Languages: Implications for English Language Pedagogy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tosin%20Samson%20Olagunju">Tosin Samson Olagunju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is a contrastive study of affixation in Ipe and Yoruba Languages with the aim of looking at the implications for English pedagogy. This study, with the use of Hocket's Theory of Item and Arrangement and Word and Paradigm (as expatiated by Crystal), examines the aspect of affixation in Ipe and Yoruba Languages with the help of contrastive analysis which provides a basis for contrasting the morphological patterns of two different indigenous languages. It examines four affixes: prefix, infix, interfix, and suffix with numerous examples in the languages under investigation. The study is corpus based as it depends primarily on the words available in the lexicon of the languages under examination. Data were elicited from both monolingual and bilingual native-speakers of Ipe Language and Yoruba Language in Ipe-Akoko and Oyo respectively. Ibadan 400-wordlist was utilised as a tool for collecting data from informants who are between age fifty and seventy through audio recording as it is believed that they are the custodians of culture and tradition. Consequently, the study reveals that Ipe and Yoruba morphology have affixation such as prefix, interfix, and suffix. It also finds out that 'infix' is an unproductive aspect in English, Ipe, and Yoruba; although a few examples are in English. Interfix is very productive in Ipe and Yoruba but not in English at all. Phonologically, it is discovered that Ipe language has the two dental fricative consonants just like the English language, i.e., /Ɵ/ and /ð/. This is rare among the indigenous languages in Nigeria. This research believes that in the teaching of English consonants to the people of Ipe-Akoko, such areas will be taught with ease. The study concludes that morphological processes of Nigerian indigenous languages are studied the more so that they will not face endangerment which can lead to extinction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affixation" title="affixation">affixation</a>, <a href="https://publications.waset.org/abstracts/search?q=contrastive%20study" title=" contrastive study"> contrastive study</a>, <a href="https://publications.waset.org/abstracts/search?q=Ipe" title=" Ipe"> Ipe</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=pedagogy" title=" pedagogy"> pedagogy</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoruba" title=" Yoruba"> Yoruba</a> </p> <a href="https://publications.waset.org/abstracts/101152/a-contrastive-study-of-affixation-in-ipe-and-yoruba-languages-implications-for-english-language-pedagogy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101152.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">297</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">29</span> Comparative Effects of Convective Drying on the Qualities of Some Leafy Vegetables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iyiola%20Olusola%20Oluwaleye">Iyiola Olusola Oluwaleye</a>, <a href="https://publications.waset.org/abstracts/search?q=Samson%20A.%20Adeleye"> Samson A.

The vegetables investigated are spinach (Amaranthus cruentus); water leaf (Talinum triangulare); lettuce (Lactuca satuva); and fluted pumpkin (Telfaria occidentalis). These vegetables are available in abundance during raining season and are commonly consumed by average Nigerians. A convective dryer was used for the drying process at the stipulated temperatures which were maintained with the aid of a thermostat. The vegetable samples after washing was cut into smaller sizes of 0.4 cm-0.5 cm and loaded into the drying cage of the convective dryer. The daily duration of the drying is six hours from 9:00 am to 3:00 pm. The dried samples were thereafter subjected to microbial and proximate analyses. The result of the tests shows that the microbial load decreases as the drying temperature increases. As temperature increases, the moisture content and carbohydrate of all the samples decreases while the crude fiber, ash and protein increases. Percentage fat content decreases as drying temperature increases with the exception of fluted pumpkin. The shelf life of the vegetable samples increase with drying temperature, Spinach has the lowest shelf life followed by Fluted Pumpkin, followed by lettuce while Water Leaf has the highest shelf life at the three drying temperatures of 50ᵒC, 60ᵒC and 70ᵒC respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convective%20drying" title="convective drying">convective drying</a>, <a href="https://publications.waset.org/abstracts/search?q=leafy%20vegetables" title=" leafy vegetables"> leafy vegetables</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=shelf%20life" title=" shelf life"> shelf life</a> </p> <a href="https://publications.waset.org/abstracts/59995/comparative-effects-of-convective-drying-on-the-qualities-of-some-leafy-vegetables" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59995.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">264</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">28</span> Manipulative Figurative Linguistic Violence of Contemporary National Anthems: A Socio-Cognitive Critical Discourse Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20Olasunkanmi%20Oluga">Samson Olasunkanmi Oluga</a>, <a href="https://publications.waset.org/abstracts/search?q=Teh%20Chee%20Send"> Teh Chee Send</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Sagaya%20Raj%20Rajo"> Gerard Sagaya Raj Rajo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is ironical that the national anthems of many nations that are in the forefront of the global condemnation of violence of all forms have portions or expressions that propagate various forms of linguistic violence which advocate attacking opponents, going to war, shedding blood and sacrificing lives. These diametrically contradict contemporary yearnings for global tranquility and the ideals of the United Nations established for the maintenance of international peace and harmony aimed at making the world a safe haven for all and sundry. The linguistic violence of many national anthems is manipulatively constructed /presented via the instrumentality of the figurative or rhetorical language. This helps to linguistically embellish the violent ideas communicated and makes them sound somehow better or logical to the target audience with the intention of cognitively manipulating them to accept or rationalize such violent ideas. This paper, therefore, presents the outcome of a linguistic exploration/examination of national anthems which reveals elements or cases manipulative figurative linguistic violence in the anthems of twenty-one (21) nations. The paper details a Socio-Cognitive Critical Discourse Analysis of the manipulative figures of comparison, contrast, indirectness, association and sound used to convey the linguistic violence of the identified national anthems. Finally, the paper advocates the need for linguistic overhaul of affected anthems so that the language of anthems which epitomize nations can be pacific and in tandem with contemporary global trends. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=national%20anthems" title="national anthems">national anthems</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20violence" title=" linguistic violence"> linguistic violence</a>, <a href="https://publications.waset.org/abstracts/search?q=figurative%20language" title=" figurative language"> figurative language</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive" title=" cognitive"> cognitive</a>, <a href="https://publications.waset.org/abstracts/search?q=manipulation" title=" manipulation"> manipulation</a>, <a href="https://publications.waset.org/abstracts/search?q=CDA" title=" CDA "> CDA </a> </p> <a href="https://publications.waset.org/abstracts/37767/manipulative-figurative-linguistic-violence-of-contemporary-national-anthems-a-socio-cognitive-critical-discourse-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37767.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">332</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> Assessment of the Use of Participatory Research Methods among Researchers in Federal University of Agriculture Abeokuta, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20Olusegun%20Apantaku">Samson Olusegun Apantaku</a>, <a href="https://publications.waset.org/abstracts/search?q=Adetayo%20K.%20Aromolaran"> Adetayo K.

Simple random sampling technique was used to select one hundred and twenty respondents from the study area. Data were collected using a questionnaire. Data collected were subjected to descriptive and inferential statistical analyses. Results showed that 75.8% of the respondents were males while only 21.3% were female. The mean age of the respondents was 38.8 years and most (77.5%) of them were married. 15% of the respondents were in professorial cadre, 21.7% and 20% of the respondents were senior lecturers/fellow and lecturer/research fellow I&II respectively. The results further revealed that 93.3% of the respondents were aware of participatory research methods and 82.5% of the respondents have utilized it before. The average period of usage was 2.7 years and participation by consultation (86.7%) and interactive participation (76.7%) were mostly used. Most (94.2%) indicated that fund was the major hindrance to the use of participatory research methods. The result of correlation analysis showed that there was significant relationship between the years of research experience, designation post (status) of the respondents and usage of participatory research methods (r = 0.034, 0.031, p < 0.05). The study concluded that most of the researchers were aware of and used participatory research methods, which could influence the quality of their research or make it acceptable to the end users. It was recommended that more funds should be made available and accessible for participatory research. All researchers should be trained and encouraged to make use of participatory research methods in their research activities so as to achieve effective research and capacity building that could enhance adoption of technologies and increase agricultural production in the country. Farmers’ capacity to participate in agricultural research should also be enhanced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=participatory%20research" title="participatory research">participatory research</a>, <a href="https://publications.waset.org/abstracts/search?q=participatory%20research%20methods" title=" participatory research methods"> participatory research methods</a>, <a href="https://publications.waset.org/abstracts/search?q=awareness" title=" awareness"> awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization" title=" utilization "> utilization </a> </p> <a href="https://publications.waset.org/abstracts/13418/assessment-of-the-use-of-participatory-research-methods-among-researchers-in-federal-university-of-agriculture-abeokuta-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13418.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">419</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> Proximate Composition, Colour and Sensory Properties of Akara egbe Prepared from Bambara Groundnut (Vigna subterranea)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20A.%20Oyeyinka">Samson A.

Hence, it could be used in making traditional snack usually produced from cowpea paste. In this study, akara egbe, a traditional snack was prepared from Bambara groundnut flour or paste. Cowpea was included as the reference sample. The proximate composition and functional properties of the flours were studies as well as the proximate composition and sensory properties of the resulting akara egbe. Protein and carbohydrate were the main components of Bambara groundnut and cowpea grains. Ash, fat and fiber contents were low. Bambara groundnut flour had higher protein content (23.71%) than cowpea (19.47%). In terms of functional properties, the oil absorption capacity (0.75 g oil/g flour) of Bambara groundnut flour was significantly (p ≤ 0.05) lower than that of the cowpea (0.92 g oil/g flour), whereas, Cowpea flour absorbed more water (1.59 g water/g flour) than Bambara groundnut flour (1.12 g/g). The packed bulk density (0.92 g/mL) of Bambara groundnut was significantly (p ≤ 0.05) higher than cowpea flour (0.82 g/mL). Akara egbe prepared from Bambara groundnut flour showed significantly (p ≤ 0.05) higher protein content (23.41%) than the sample made from Bambara groundnut paste (19.35%). Akara egbe prepared from cowpea paste had higher ratings in aroma, colour, taste, crunchiness and overall acceptability than those made from cowpea flour or Bambara groundnut paste or flour. Bambara groundnut can produce akara egbe with comparable nutritional and sensory properties to that made from cowpea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bambara%20groundnut" title="Bambara groundnut">Bambara groundnut</a>, <a href="https://publications.waset.org/abstracts/search?q=Cowpea" title=" Cowpea"> Cowpea</a>, <a href="https://publications.waset.org/abstracts/search?q=Snack" title=" Snack"> Snack</a>, <a href="https://publications.waset.org/abstracts/search?q=Sensory%20properties" title=" Sensory properties"> Sensory properties</a> </p> <a href="https://publications.waset.org/abstracts/78671/proximate-composition-colour-and-sensory-properties-of-akara-egbe-prepared-from-bambara-groundnut-vigna-subterranea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78671.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">264</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> Effect of Extraction Methods on the Fatty Acids and Physicochemical Properties of Serendipity Berry Seed Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olufunmilola%20A.%20Abiodun">Olufunmilola A.

The vine grows during the raining season and is used mainly as sweetener. The sweetener in the berry is known as monellin which is sweeter than sucrose. The sweetener is extracted from the fruits and the seed is discarded. The discarded seeds contain bitter principles but had high yield of oil. Serendipity oil was extracted using three methods (N-hexane, expression and expression/n-hexane). Fatty acids and physicochemical properties of the oil obtained were determined. The oil obtained was clear, liquid and have odour similar to hydrocarbon. The percentage oil yield was 38.59, 12.34 and 49.57% for hexane, expression and expression-hexane method respectively. The seed contained high percentage of oil especially using combination of expression and hexane. Low percentage of oil was obtained using expression method. The refractive index values obtained were 1.443, 1.442 and 1.478 for hexane, expression and expression-hexane methods respectively. Peroxide value obtained for expression-hexane was higher than those for hexane and expression. The viscosities of the oil were 125.8, 128.76 and 126.87 cm³/s for hexane, expression and expression-hexane methods respectively which showed that the oil from expression method was more viscous than the other oils. The major fatty acids in serendipity seed oil were oleic acid (62.81%), linoleic acid (22.65%), linolenic (6.11%), palmitic acid (5.67%), stearic acid (2.21%) in decreasing order. Oleic acid which is monounsaturated fatty acid had the highest value. Total unsaturated fatty acids were 91.574, 92.256 and 90.426% for hexane, expression, and expression-hexane respectively. Combination of expression and hexane for extraction of serendipity oil produced high yield of oil. The oil could be refined for food and non-food application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serendipity%20seed%20oil" title="serendipity seed oil">serendipity seed oil</a>, <a href="https://publications.waset.org/abstracts/search?q=expression%20method" title=" expression method"> expression method</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid" title=" fatty acid"> fatty acid</a>, <a href="https://publications.waset.org/abstracts/search?q=hexane" title=" hexane"> hexane</a> </p> <a href="https://publications.waset.org/abstracts/79242/effect-of-extraction-methods-on-the-fatty-acids-and-physicochemical-properties-of-serendipity-berry-seed-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79242.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">273</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">24</span> Prevalence and Pattern of Drug Usage among Youth in Ogbomoso, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20F.%20Agberotimi">Samson F.

There is, however, a paucity of literature addressing the pattern of usage of such drugs, especially for clinical relevance and intervention planning. The present study investigated the prevalence and pattern of drug usage among youth in Ogbomoso, Nigeria. A cross-sectional survey involving 92 purposively selected participants comprising of 82 males and 10 females aged between 15 and 24 years was conducted. A measure of drug involvement and demographic characteristics was administered to the participants. Descriptive analysis was done using the SPSS v.21. Cannabis (79.4%), alcohol (77.2%), codeine (70.7%), tobacco (65.2%) and tramadol (47.8%) are the five most frequently used substances. However, the majority of the users of tobacco (68.3%) and alcohol (62.0%) are casual users indicating a mild level of use of the substances among the participants. On the other hand, 49.2% of the codeine users, 27.3% of the tramadol users, and 21.9% of the cannabis users reported harmful/intensive levels of use. Furthermore, the results revealed individuals at the pathological level of use as 28.8% for cannabis, 25.0% for tramadol, and 21.6% for codeine, and thus require clinical/therapeutic intervention. In conclusion, cannabis remains the most frequently used substance among youths. However, there appears to be a shift from the use of conventional psychoactive substances to pharmaceutical/prescription drugs such as codeine and tramadol. The findings of this study raised the need for both preventive and therapeutic interventions addressing the problem of substance use disorder among youth in contemporary society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ogbomoso" title="Ogbomoso">Ogbomoso</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20of%20drug%20use" title=" pattern of drug use"> pattern of drug use</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence%20of%20drug%20use" title=" prevalence of drug use"> prevalence of drug use</a>, <a href="https://publications.waset.org/abstracts/search?q=youth" title=" youth"> youth</a> </p> <a href="https://publications.waset.org/abstracts/117233/prevalence-and-pattern-of-drug-usage-among-youth-in-ogbomoso-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117233.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">170</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> Stabilization of Spent Engine Oil Contaminated Lateritic Soil Admixed with Cement Kiln Dust for Use as Road Construction Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johnson%20Rotimi%20Oluremi">Johnson Rotimi Oluremi</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Adedayo%20Adegbola"> A.

It affects geotechnical properties of lateritic soil thereby constituting geotechnical and foundation problems. This study is therefore based on the stabilization of spent engine oil (SEO) contaminated lateritic soil using cement kiln dust (CKD) as a mean of restoring it to its pristine state. Geotechnical tests which include sieve analysis, atterberg limit, compaction, California bearing ratio and unconfined compressive strength tests were carried out on the natural, SEO contaminated and CKD stabilized SEO contaminated lateritic soil samples. The natural soil classified as A-2-7 (2) by AASHTO classification and GC according to the Unified Soil Classification System changed to A-4 non-plastic soil due to SEO contaminated even under the influence of CKD it remained unchanged. However, the maximum dry density (MDD) of the SEO contaminated soil increased while the optimum moisture content (OMC) behaved vice versa with the increase in the percentages of CKD. Similarly, the bearing strength of the stabilized SEO contaminated soil measured by California Bearing Ratio (CBR) increased with percentage increment in CKD. In conclusion, spent engine oil has a detrimental effect on the geotechnical properties of the lateritic soil sample but which can be remediated using 10% CKD as a stand alone admixture in stabilizing spent engine oil contaminated soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spent%20engine%20oil" title="spent engine oil">spent engine oil</a>, <a href="https://publications.waset.org/abstracts/search?q=lateritic%20soil" title=" lateritic soil"> lateritic soil</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20kiln%20dust" title=" cement kiln dust"> cement kiln dust</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=compaction" title=" compaction"> compaction</a>, <a href="https://publications.waset.org/abstracts/search?q=unconfined%20compressive%20strength" title=" unconfined compressive strength"> unconfined compressive strength</a> </p> <a href="https://publications.waset.org/abstracts/71051/stabilization-of-spent-engine-oil-contaminated-lateritic-soil-admixed-with-cement-kiln-dust-for-use-as-road-construction-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71051.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">389</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> Effect of Seasonal Variation on Two Introduced Columbiformes in Awba Dam Tourism Centre, University of Ibadan, Ibadan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kolawole%20F.%20Farinloye">Kolawole F.

Ojo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two Columbiformes species were recently introduced to the newly established Awba Dam Tourism Centre [ADTC], hence there is need to investigate the effect of seasonal variation on these species with respect to hematological composition. Blood samples were obtained from superficial ulna vein of the 128 apparently healthy C. livia and C. guinea into tubes containing EDTA as anticoagulant. Thin blood smears (TBS) were prepared, stained and viewed under microscope. Values of Red Blood Cell (RBC) count, White Blood Cell (WBC) count, cholesterol (CH), Uric Acid (UA), Protein (PR), Mean Corpuscular Volume (MCV), Haemoglobin Content (HB), Blood Volume (BV), Plasma Glucose (PG) and Length/Width (L/W) ratio of red blood cells were assessed. The procedure was carried out on a seasonal basis (wet and dry seasons of 2013-2014). Data was analyzed using descriptive and inferential statistics. Lymphocyte count for C. livia was F3, 161 = 13.15, while for C. guinea was F3, 178 = 13.15. Heterophil, H/L ratio and Muscle score values for both species were (rs = -0.38, rs = -0.44), (rs = 0.51, rs = 0.31) (4, 3) respectively. Analyses also demonstrated a low WBC to RBC ratio (0.004: 25.3) in both species during the wet season compared to dry season, respectively. L/W varied significantly among sampling seasons i.e. wet (19.1% of BV, 12.6% of BV, 0.1% of BV) and dry (18.9% of BV, 12.7% of BV, 0.08% of BV). The level of HB in wet season (19.20±8.46108) is lower compared to dry season (19.70±8.48762). T-test also showed (wet=15.625, 0.111), (dry=12.125, 0.146) respectively, hence there is no association between species and haematological parameters. Species introduced were found to be haematologically stable. Although there were slight differences in seasonal composition, however this can be attributed to seasonal variation; suggesting little or no effect of seasons on their blood composition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=seasonal%20variation" title="seasonal variation">seasonal variation</a>, <a href="https://publications.waset.org/abstracts/search?q=Columbiformes" title=" Columbiformes"> Columbiformes</a>, <a href="https://publications.waset.org/abstracts/search?q=Awba%20Dam%20tourism%20centre" title=" Awba Dam tourism centre"> Awba Dam tourism centre</a>, <a href="https://publications.waset.org/abstracts/search?q=University%20of%20Ibadan" title=" University of Ibadan"> University of Ibadan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibadan" title=" Ibadan"> Ibadan</a> </p> <a href="https://publications.waset.org/abstracts/71108/effect-of-seasonal-variation-on-two-introduced-columbiformes-in-awba-dam-tourism-centre-university-of-ibadan-ibadan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71108.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">341</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> Educators’ Adherence to Learning Theories and Their Perceptions on the Advantages and Disadvantages of E-Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samson%20T.%20Obafemi">Samson T.

However, the hope placed in ICTs to find viable solutions to the problem of poor academic performance in schools in the developing world has not yet yielded the expected benefits. This problem serves as a motivation to this study whose aim is to examine the perceptions of educators on the advantages and disadvantages of e-learning. This aim will be subdivided into two types of research objectives. Objectives on the identification and design of theories and models will be achieved using content analysis and literature review. However, the objective on the empirical testing of such theories and models will be achieved through the survey of educators from different schools in the Pinetown District of the South African Kwazulu-Natal province. SPSS is used to quantitatively analyse the data collected by the questionnaire of this survey using descriptive statistics and Pearson correlations after assessing the validity and the reliability of the data. The main hypothesis driving this study is that there is a relationship between the demographics of educators’ and their adherence to learning theories on one side, and their perceptions on the advantages and disadvantages of e-learning on the other side, as argued by existing research; but this research views these learning theories under three perspectives: educators’ adherence to self-regulated learning, to constructivism, and to progressivism. This hypothesis was fully confirmed by the empirical study except for the demographic factor where teachers’ level of education was found to be the only demographic factor affecting the perceptions of educators on the advantages and disadvantages of e-learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20performance" title="academic performance">academic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20theories" title=" learning theories"> learning theories</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning" title=" teaching and learning"> teaching and learning</a> </p> <a href="https://publications.waset.org/abstracts/14970/educators-adherence-to-learning-theories-and-their-perceptions-on-the-advantages-and-disadvantages-of-e-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14970.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">273</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> Sequence Polymorphism and Haplogroup Distribution of Mitochondrial DNA Control Regions HVS1 and HVS2 in a Southwestern Nigerian Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ogbonnaya%20O.%20Iroanya">Ogbonnaya O.

Knowledge of variation within populations has been employed in forensic and molecular anthropology studies. The study was aimed at investigating the polymorphic nature of the two hypervariable segments (HVS) of the mtDNA, i.e., HVS1 and HVS2, and to determine the haplogroup distribution among individuals resident in Lagos, Southwestern Nigeria. Peripheral blood samples were obtained from sixty individuals who are not related maternally, followed by DNA extraction and amplification of the extracted DNA using primers specific for the regions under investigation. DNA amplicons were sequenced, and sequenced data were aligned and compared to the revised Cambridge Reference Sequence (rCRS) GenBank Accession number: NC_012920.1) using BioEdit software. Results obtained showed 61 and 52 polymorphic nucleotide positions for HVS1 and HVS2, respectively. While a total of three indels mutation were recorded for HVS1, there were seven for HVS2. Also, transition mutations predominate nucleotide change observed in the study. Genetic diversity (GD) values for HVS1 and HVS2 were estimated to be 84.21 and 90.4%, respectively, while random match probability was 0.17% for HVS1 and 0.89% for HVS2. The study also revealed mixed haplogroups specific to the African (L1-L3) and the Eurasians (U and H) lineages. New polymorphic sites obtained from the study are promising for human identification purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hypervariable%20region" title="hypervariable region">hypervariable region</a>, <a href="https://publications.waset.org/abstracts/search?q=indels" title=" indels"> indels</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondrial%20DNA" title=" mitochondrial DNA"> mitochondrial DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20match%20probability" title=" random match probability"> random match probability</a> </p> <a href="https://publications.waset.org/abstracts/125506/sequence-polymorphism-and-haplogroup-distribution-of-mitochondrial-dna-control-regions-hvs1-and-hvs2-in-a-southwestern-nigerian-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125506.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">19</span> Study of Causes and Effects of Road Projects Abandonment in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monsuru%20Oyenola%20Popoola">Monsuru Oyenola Popoola</a>, <a href="https://publications.waset.org/abstracts/search?q=Oladapo%20Samson%20Abiola"> Oladapo Samson Abiola</a>, <a href="https://publications.waset.org/abstracts/search?q=Wusamotu%20Alao%20Adeniji"> Wusamotu Alao Adeniji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The prevalent and incessant abandonment of road construction projects are alarming that it creates several negative effects to social, economic and environmental values of the project. The purpose of this paper is to investigate and determined the various causes and effects of abandoning road construction projects in Nigeria. Likert Scale questionnaire design was used to administered and analysed the data obtained for the stydy. 135 (Nr) questionnaires were completed and retrieved from the respondents, out of 200 (Nr) questionnaires sent out, representing a response rate of 67.5%. The analysis utilized the Relative Importance Index (R.I.I.) method and the results are presented in tabular form. The findings confirms that at least 20 factors were the causes of road projects abandonment in Nigeria with most including Leadership Instability, Improper Project Planning, Inconsistence in government policies and Design, Contractor Incompetence, Economy Instability and Inflation, Delay in remittance of money, Improper financial analysis, Poor risk management, Climatic Conditions, Improper Project Estimates etc. The findings also show that at least eight (8) effect were identified on the system, and these include; Waste of Financial Resources, Loss of economic value, Environmental degradation, Loss of economic value, Reduction in standard of living, Litigation and Arbitration, etc. The reflection is that allocating reasonable finance, developing appropriate and effective implementation plans and monitoring, evaluation and reporting on development project activities by key actors should enhance in resolving the problem of road projects abandonment. <p
