Fermentation followed the conventional traditional method of fermented locust bean (iru) production and was carried out over a period of three days (72 hours). Samples were withdrawn and analysed for proximate composition, pH, titratable acidity, tannin content, phytic acid content and trypsin inhibitor activity using standard methods. Effects of fermentation on proximate composition, anti-nutritional factors and sensory properties of the seed were evaluated. All data were analysed using ANOVA and means separated using Duncan multiple range test. Microbiological analysis to identify and characterize the microflora responsible for the fermentation of the seed was also carried out. Fermentation had significant effect on the proximate composition on the fermented seeds. As fermentation progressed, there was significant reduction in the anti-nutrient contents. Organisms isolated from the fermenting tamarind seeds were identified as non-pathogenic and common with fermented legumes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=condiment" title="condiment">condiment</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation"> fermentation</a>, <a href="https://publications.waset.org/abstracts/search?q=legume" title=" legume"> legume</a>, <a href="https://publications.waset.org/abstracts/search?q=tamarind%20seed" title=" tamarind seed"> tamarind seed</a> </p> <a href="https://publications.waset.org/abstracts/8682/solid-state-fermentation-of-tamarind-tamarindus-indica-seed-to-produce-food-condiment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8682.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">37</span> Functional, Pasting and Colour Characteristics of OGI (A Fermented Maize Meal) as Affected by Stage of Moringa Seed Inclusion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olajide%20Emmanuel%20Adedeji">Olajide Emmanuel Adedeji</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufunke%20O.%20Ezekiel"> Olufunke O.

Functional, pasting and L*a*b* colour characteristics of the samples were determined using standard methods. Loose and packed bulk densities ranged from 0.32 to 0.39 g/cm3 and 0.57 to 0.70 g/cm3 respectively. 100% ogi flour had the lowest values in both parameters. Water absorption and swelling capacities of the samples ranged from 0.89 to 1.80 ml/g and from 5.81 to 6.99 respectively. Pasting viscosity ranged from 870.33 RVU to 4660.67 RVU with the sample produced through the incorporation of full fat moringa seed flour during souring stage and 100% ogi flour having the least and highest values respectively. Stage of moringa seed inclusion also had effect on the trough, breakdown and final viscosity of the samples. The range of values obtained for these pasting parameters were 599.33-2940.00 RVU, 271.00-1720.67 RVU and 840.00-5451.67 RVU respectively. There was no significant difference (p≥ 0.05) in L*(a measure of whiteness) among the co fermented, blend of ogi and full fat moringa flours, blend of ogi and defatted moringa flour and 100% ogi flour samples. Low values were recorded for these samples in a* (measure of redness), b* (measure of yellowness) and colour intensity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stage%20of%20inclusion" title="stage of inclusion">stage of inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=functional%20property" title=" functional property"> functional property</a>, <a href="https://publications.waset.org/abstracts/search?q=ogi" title=" ogi"> ogi</a>, <a href="https://publications.waset.org/abstracts/search?q=moringa%20seed" title=" moringa seed"> moringa seed</a> </p> <a href="https://publications.waset.org/abstracts/26583/functional-pasting-and-colour-characteristics-of-ogi-a-fermented-maize-meal-as-affected-by-stage-of-moringa-seed-inclusion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26583.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">487</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> Diversification of Sweet Potato Blends and Utilization for Malnutrition and Poverty Alleviation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ladele%20Ademola%20A.">Ladele Ademola A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Nkiru%20T.%20Meludu"> Nkiru T.

The study was carried out in Nigeria to determine the acceptability of blends sweet potato (Ipomea batatas) and commodities yellow maize (Zea mays), millet (Pennisetum glaucum), soybean (Glycine max), bambara groundnut (Vigna subterranean), guinea corn (Sorghum vulgare), wheat (Triticum aestivum), and roselle (Hibiscus sabdariffa) through sensory evaluation. Sweet potato (Ipomea batatas) roots were processed using two methods. The first method involved the use of a fabricated gas powered cabinet dryer to dry sulphited chips and the second method was the use of traditional sun drying method without the addition of the chemical. The blends were also assessed in terms of functional, chemical and color properties. Most acceptable blends include BAW (80:20 of sweet potato/wheat), BBC (80:20 of sweet potato/guinea corn), AAB (60:40 of sweet potato/guinea corn), YTE (100% soybean), TYG (100% sweet potato), KTN (100% wheat flour), XGP (80:20 of sweet potato/soybean), XAX (60:40 of sweet potato/wheat), LSS (100% Roselle), CHK (100% Guinea corn), and ABC (60:40% of sweet potato/ yellow maize). In addition, chemical analysis carried out revealed that sweet potato has high percentage of vitamins A and C, potassium (K), manganese (Mn), calcium (Ca), magnesium (Mg) and iron (Fe) and fibre content. There is also an increase of vitamin A and Iron in the blended products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blends" title="blends">blends</a>, <a href="https://publications.waset.org/abstracts/search?q=diversification" title=" diversification"> diversification</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20evaluation" title=" sensory evaluation"> sensory evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=sweet%20potato" title=" sweet potato"> sweet potato</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization" title=" utilization"> utilization</a> </p> <a href="https://publications.waset.org/abstracts/26905/diversification-of-sweet-potato-blends-and-utilization-for-malnutrition-and-poverty-alleviation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26905.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">506</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> Newly Developed Epoxy-Polyol and Epoxy- Polyurethane from Renewable Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akintayo%20Emmanuel%20Temitope">Akintayo Emmanuel Temitope</a>, <a href="https://publications.waset.org/abstracts/search?q=Akintayo%20Cecilia%20Olufunke"> Akintayo Cecilia Olufunke</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziegler%20Thomas"> Ziegler Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bio-polyols are important components in polyurethane industries. The preliminary studies into the synthesis of bio-polyol products (epoxy-polyol and epoxyl-polyurethanes) from Jatropha curcas were investigated. The reactions were followed by both infrared and nuclear magnetic resonance. Physico-chemical characterisation of the samples for iodine value (IV), acid value (AV), saponification value (SV) and hydroxyl value (HV) were carried out. Thermal transitions of the products were studied by heating 5 mg of the sample from 20ºC to 800ºC and then cooling down to -500ºC on a differential scanning calorimeter (DSC). The preparation of epoxylpolyol and polyurethane from Jatropha curcas oil was smooth and efficient. Results of film and solubility properties revealed that coatings of Jatropha curcas epoxy-polyurethanes performed better with increased loading of toluylene 2, 4-diisocyanate (TDI) up to 2 wt% while their solvent resistance decreased beyond a TDI loading of 1.2 wt%. DSC analysis shows the epoxy-polyurethane to be less stable compared to the epoxy-polyol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=synthesis" title="synthesis">synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy-polyol" title=" epoxy-polyol"> epoxy-polyol</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy-polyurethane" title=" epoxy-polyurethane"> epoxy-polyurethane</a>, <a href="https://publications.waset.org/abstracts/search?q=jatropha%20curcas%20oil" title=" jatropha curcas oil"> jatropha curcas oil</a> </p> <a href="https://publications.waset.org/abstracts/6080/newly-developed-epoxy-polyol-and-epoxy-polyurethane-from-renewable-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6080.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">34</span> WebGIS Development Framework With Prioritized Usability Elements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ezekiel%20Mwangi">Ezekiel Mwangi</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephen%20Kimani"> Stephen Kimani</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnes%20Mindila"> Agnes Mindila</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Usability is one of the key factors that determine the success or failure of any WebGIS (technology normally applied on the internet to analyze and present spatial data on the Internet). However, not all the usability attributes have the same impact on usability. It is, therefore, necessary to prioritize WebGIS usability elements and determine the ones that are more crucial to the success of the WebGIS. This research aims to identify the main elements of WebGIS usability, investigate the order of importance and priority of the usability elements of WebGIS, and propose a WebGIS development framework that incorporates the prioritization of the usability elements. This will be achieved through a literature review. The outcome of this research will help usability specialists and WebGIS developers in determining specific usability elements that should be accorded more emphasis during the design and development of WebGIS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=framework" title="framework">framework</a>, <a href="https://publications.waset.org/abstracts/search?q=prioritization" title=" prioritization"> prioritization</a>, <a href="https://publications.waset.org/abstracts/search?q=usability" title=" usability"> usability</a>, <a href="https://publications.waset.org/abstracts/search?q=WebGIS" title=" WebGIS"> WebGIS</a> </p> <a href="https://publications.waset.org/abstracts/129371/webgis-development-framework-with-prioritized-usability-elements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129371.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">158</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Implicit Off-Grid Block Method for Solving Fourth and Fifth Order Ordinary Differential Equations Directly</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Ezekiel%20Abolarin">Olusola Ezekiel Abolarin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gift%20E.%20Noah"> Gift E.

CT imaging confirmed the presence of right preseptal cellulitis and lacrimal sac aspiration identified multi-resistant Enterobacter cloacae. A diagnosis of acute right-sided dacryocystitis with preseptal cellulitis was made. He was successfully treated with broadening of antibiotic therapy to intravenous meropenem. The symptomatic resolution was noted on follow-up without evidence of disease recurrence. To the Authors’ best knowledge, this is the first reported case of multi-resistant E. cloacae dacryocystitis and preseptal cellulitis.

Hence, an experiment was conducted to investigate the in vitro fermentation pattern, methane production, and performance of West African dwarf (WAD) rams-fed diets at graded levels of ginger. Sixteen (16) rams were randomly allocated into four dietary treatments with four animals per treatment in a completely randomized design for 84 days. Ginger powder was added at 0.00%, 0.25%, 0.50% and 0.75% as T1, T2, T3 and T4 respectively. The results indicated that at the 24-hour diet incubation, gas production, methane, metabolizable energy (ME), organic matter digestibility (OMD), and short-chain fatty acids (SCFA) concentrations decreased with the increasing level of ginger. Conversely, the sheep-fed T4 recorded the highest daily weight gain (47.61g/day), while the least daily weight gain (17.86g/day) was recorded in ram-fed T1. The daily weight gain of the rams fed T3 and T4 was similar but significantly different from the daily weight gain in T1 (17.86g/day) and T2 (29.76g/day). Daily feed intake was not significantly different across the treatments. T4 recorded the best response regarding feed conversion ratio (18.59) compared with other treatments. Based on the results obtained, rams fed T4 perform best in terms of growth and methane production. It is therefore concluded that the addition of ginger powder into the diet of sheep up to 0.75% enhances the growth rate of WAD sheep and reduces enteric methane production to create a smart nutrition system in ruminant animal production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=enteric%20methane" title="enteric methane">enteric methane</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=in%20vitro" title=" in vitro"> in vitro</a>, <a href="https://publications.waset.org/abstracts/search?q=sheep" title=" sheep"> sheep</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition%20system" title=" nutrition system"> nutrition system</a> </p> <a href="https://publications.waset.org/abstracts/171151/effect-of-ginger-diets-on-in-vitro-fermentation-characteristics-enteric-methane-production-and-performance-of-west-african-dwarf-sheep" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171151.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">78</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> Managing Construction Wastes in Nigeria for Sustainable Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ezekiel%20Ejiofor%20Nnadi">Ezekiel Ejiofor Nnadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nigeria construction industry is known for its active construction activities. This has earmarked the industry to be the key to economic growth of the nation. It has largest employer of labour and gives sustenance to other industries like manufacturing industry. While this is a sign of growth and prosperity; the waste generated by the industry has always been a problem and a serious concern. It results in wastage of economic gain and has resultant health effect on the populace apart from injury being sustained on sites. This work provides a platform to learn more about construction waste, its management strategy and how to reduce waste production in Nigeria construction industry. Construction sites, waste management authority and public health institutions in Lagos as the centre of most construction activities in Nigeria were selected, and a set of questionnaire was administered to using the systematic sampling technique. Descriptive statistics and relative importance index (RII) technique were employed for the analysis of the data gathered. The findings of the analysis show that excessive wastes reduce contractors’ profit margin and also that some construction wastes contain hazardous and toxic elements such as lead, asbestos or radioactive materials which required proper handling and effective disposal. The conclusion was drawn that the check on waste on construction sites starts with the designers to the contractors who execute on site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20cost" title="construction cost">construction cost</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20industry" title=" construction industry"> construction industry</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20wastes" title=" materials wastes"> materials wastes</a> </p> <a href="https://publications.waset.org/abstracts/85649/managing-construction-wastes-in-nigeria-for-sustainable-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85649.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">29</span> Superficial Metrology of Organometallic Chemical Vapour Deposited Undoped ZnO Thin Films on Stainless Steel and Soda-Lime Glass Substrates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uchenna%20Sydney%20Mbamara">Uchenna Sydney Mbamara</a>, <a href="https://publications.waset.org/abstracts/search?q=Bolu%20Olofinjana"> Bolu Olofinjana</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezekiel%20Oladele%20B.%20Ajayi"> Ezekiel Oladele B.

Ultraviolet-visible-near-infrared (UV-Vis-NIR) spectroscopy showed that all the thin films were over 80% transparent, with an average bandgap of 3.39 eV, X-ray diffraction (XRD) results showed that the thin films were crystalline with a hexagonal structure, while Rutherford backscattering spectroscopy (RBS) results identified the elements present in each thin film as zinc and oxygen in the ratio of 1:1. Microscope and contactless profilometer results gave images with characteristic colours. The profilometer also gave the surface roughness data in both 2D and 3D. The asperity distribution of the thin film surfaces was Gaussian, while the average fractal dimension Da was in the range of 2.5 ≤ Da.

They also respond to stress in different ways. An inspiration was to study stress development amongst workers in a work dangerous setting (Construction Industry) as well as how they cope with specific stress incidences. Objective: The overarching objective of the study was to study and correlate between stress and coping strategies. The research was conducted in an organizational industrial setting, and its findings on the coping actions of construction workers are reported in this article. Methods: An online cross-sectional survey was conducted with 80 participants aged 18-62. These were working for three different construction organizations in the West Midland region of the UK. Their coping actions were assessed using the COPE Inventory (Carver, 2013) instrument while the level of stress was assessed by the Perceived Stress Scale (Cohen, 1994). Results: Out of 80 workers (20 female, 25%, mean age 40.66), positive reinterpretation (M=4.15, SD=2.60) and active coping (M=4.18, SD=2.55) were the two most adaptive strategies reported by the workers while the most frequent maladaptive behavior was mental disengagement (M=3.62, SD=2.25). Among the maladaptive tactics, alcohol and drug abuse was a significant moderator in stress reactions (t=6.12, p=.000). Conclusion: Some maladaptive strategies are adopted by construction workers to cope with stress. So, it could be argued that programs of stress prevention and control in the construction industry have a basis to develop solutions that can improve and strengthen effective interventions when workers are stressed or getting stressed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coping" title="coping">coping</a>, <a href="https://publications.waset.org/abstracts/search?q=organization" title=" organization"> organization</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a> </p> <a href="https://publications.waset.org/abstracts/102736/stress-and-coping-strategies-a-correlational-analysis-to-profiling-maladaptive-behaviors-at-work" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102736.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">218</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> Extreme Value Modelling of Ghana Stock Exchange Indices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwabena%20Asare">Kwabena Asare</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezekiel%20N.%20N.%20Nortey"> Ezekiel N.

However, after the recent global financial crises, appropriate models for modelling of such rare events leading to these crises have become quite essential in the finance and risk management fields. This paper models the extreme values of the Ghana Stock Exchange All-Shares indices (2000-2010) by applying the Extreme Value Theory to fit a model to the tails of the daily stock returns data. A conditional approach of the EVT was preferred and hence an ARMA-GARCH model was fitted to the data to correct for the effects of autocorrelation and conditional heteroscedastic terms present in the returns series, before EVT method was applied. The Peak Over Threshold (POT) approach of the EVT, which fits a Generalized Pareto Distribution (GPD) model to excesses above a certain selected threshold, was employed. Maximum likelihood estimates of the model parameters were obtained and the model’s goodness of fit was assessed graphically using Q-Q, P-P and density plots. The findings indicate that the GPD provides an adequate fit to the data of excesses. The size of the extreme daily Ghanaian stock market movements were then computed using the Value at Risk (VaR) and Expected Shortfall (ES) risk measures at some high quantiles, based on the fitted GPD model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extreme%20value%20theory" title="extreme value theory">extreme value theory</a>, <a href="https://publications.waset.org/abstracts/search?q=expected%20shortfall" title=" expected shortfall"> expected shortfall</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20pareto%20distribution" title=" generalized pareto distribution"> generalized pareto distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=peak%20over%20threshold" title=" peak over threshold"> peak over threshold</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20at%20risk" title=" value at risk"> value at risk</a> </p> <a href="https://publications.waset.org/abstracts/35743/extreme-value-modelling-of-ghana-stock-exchange-indices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35743.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">558</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> Impacts of Teachers’ Cluster Model Meeting Intervention on Pupils’ Learning, Academic Achievement and Attitudinal Development in Oyo State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Joseph%20Adesina">Olusola Joseph Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina"> Abiodun Ezekiel Adesina </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Efforts at improving the falling standard of education in the country call for the need-based assessment of the primary tier of education in Nigeria. Teachers’ cluster meeting intervention is a step towards enhancing the teachers’ professional competency, efficient and effective pupils’ academic achievement and attitudinal development. The study thus determined the impact of the intervention on pupils’ achievement in Oyo State, Nigeria. Three research questions and four hypotheses guided the study. Pre-test, post-test control group, quasi-experimental design was adopted for the study. Eight intact classes from eight different schools were randomly selected into treatment and control groups. Two response instruments, pupils academic achievement test (PAAT; r = 0.87) and pupils attitude to lesson scale (PALS; r = 0.80) were used for data collection. Mean, standard deviation and analysis of covariance (ANCOVA) were used to analyse the collected data. The results showed that the teachers’ cluster meeting have significant impact on pupils academic achievement (F (1,327) =41.79; p<0.05) and attitudinal development (F (1,327) =26.01; p<0.05) in the core subjects of primary schools in Oyo State, Nigeria. The study therefore recommended among others that teachers’ cluster meeting should be sustained for teachers’ professional development and pupils’ upgradement in the State. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teachers%E2%80%99%20cluster%20meeting" title="teachers’ cluster meeting">teachers’ cluster meeting</a>, <a href="https://publications.waset.org/abstracts/search?q=pupils%E2%80%99%20academic%20achievement" title=" pupils’ academic achievement"> pupils’ academic achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=pupils%E2%80%99%20attitudinal%20development" title=" pupils’ attitudinal development"> pupils’ attitudinal development</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20achievement" title=" academic achievement "> academic achievement </a> </p> <a href="https://publications.waset.org/abstracts/8798/impacts-of-teachers-cluster-model-meeting-intervention-on-pupils-learning-academic-achievement-and-attitudinal-development-in-oyo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8798.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">25</span> A Discourse on the Rhythmic Pattern Employed in Yoruba Sakara Music of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oludare%20Olupemi%20Ezekiel">Oludare Olupemi Ezekiel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research examines the rhythmic structure of Sakara music by tracing its roots and analyzing the various rhythmic patterns of this neo-traditional genre, as well as the contributions of the major exponents and contemporary practitioners, using these as a model for understanding and establishing African rhythms. Biography of the major exponents and contemporary practitioners, interviews and participant observational methods were used to elicit information. Samples of the genre which were chosen at random were transcribed, notated and analyzed for academic use and documentation. The research affirmed that rhythms such as the Hemiola, Cross-rhythm, Clave or Bell rhythm, Percussive, Speech and Melodic rhythm and other relevant rhythmic theories were prevalent and applicable to Sakara music, while making important contributions to musical scholarship through its analysis of the music. The analysis and discussions carried out in the research pointed towards a conclusion that the Yoruba musicians are guided by some preconceptions and sound musical considerations in making their rhythmic patterns, used as compositional techniques and not mere incidental occurrence. These rhythmic patterns, with its consequential socio-cultural connotations, enhance musical values and national identity in Nigeria. The study concludes by recommending that musicologists need to carry out more research into this and other neo-traditional genres in order to advance the globalisation of African music. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compositional%20techniques" title="compositional techniques">compositional techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=globalisation" title=" globalisation"> globalisation</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=neo-traditional" title=" neo-traditional"> neo-traditional</a>, <a href="https://publications.waset.org/abstracts/search?q=rhythmic%20theory" title=" rhythmic theory"> rhythmic theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Sakara%20music" title=" Sakara music"> Sakara music</a> </p> <a href="https://publications.waset.org/abstracts/31287/a-discourse-on-the-rhythmic-pattern-employed-in-yoruba-sakara-music-of-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31287.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">442</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> Growth and Anatomical Responses of Lycopersicon esculentum (Tomatoes) under Microgravity and Normal Gravity Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gbenga%20F.%20Akomolafe">Gbenga F.

In this work, tomatoes seeds were exposed to long hours of simulated microgravity condition using a one-axis clinostat. The seeds were sown on a 1.5% combination of plant nutrient and agar-agar solidified medium in three Petri dishes. One of the Petri dishes was mounted on the clinostat and allowed to rotate at the speed of 20 rpm for 72 hours, while the others were subjected to the normal gravity vector. The anatomical sections of both clinorotated and normal gravity plants were made after 72 hours and observed using a Phase-contrast digital microscope. The percentage germination, as well as the growth rate of the normal gravity seeds, was higher than the clinorotated ones. The germinated clinorotated roots followed different directions unlike the normal gravity ones which grew towards the direction of gravity vector. The clinostat was able to switch off gravistimulation. Distinct cellular arrangement was observed for tomatoes under normal gravity condition, unlike those of clinorotated ones. The root epidermis and cortex of normal gravity are thicker than the clinorotated ones. This implied that under long-term microgravity influence, plants do alter their anatomical features as a way of adapting to the stress condition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=clinostat" title=" clinostat"> clinostat</a>, <a href="https://publications.waset.org/abstracts/search?q=germination" title=" germination"> germination</a>, <a href="https://publications.waset.org/abstracts/search?q=lycopersicon%20esculentum" title=" lycopersicon esculentum"> lycopersicon esculentum</a>, <a href="https://publications.waset.org/abstracts/search?q=microgravity" title=" microgravity"> microgravity</a> </p> <a href="https://publications.waset.org/abstracts/58028/growth-and-anatomical-responses-of-lycopersicon-esculentum-tomatoes-under-microgravity-and-normal-gravity-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58028.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">23</span> Strategic Leadership and Sustainable Project Management in Enugu, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nnadi%20Ezekiel%20Ejiofor">Nnadi Ezekiel Ejiofor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Enugu, Nigeria, this study investigates the connection between strategic leadership and project management sustainability, with an emphasis on building projects in the State. The study set out to accomplish two specific goals: first, it sought to establish a link between creative project management and resource efficiency in construction projects in Enugu State, Nigeria; and second, it sought to establish a link between innovative thinking and waste minimization in those same projects. A structured questionnaire was used to collect primary data from 45 registered construction enterprises in the study area as part of the study's descriptive research approach. Due to the nonparametric nature of the data, Spearman Rank Order Correlation was used to evaluate the acquired data. The findings demonstrate that creative project management had a significant positive impact on resource efficiency in construction projects carried out by architecture firms in Enugu State, Nigeria (r =.849; p.001), and that innovative thinking had a significant impact on waste reduction in those same projects (r =.849; p.001). It was determined that strategic leadership had a significant impact on the sustainability of project management, and it was thus advised that project managers should foresee, prepare for, and effectively communicate present and future developments to project staff in order to ensure that the objective of sustainable initiatives, such as recycling and reuse, is implemented in construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction" title="construction">construction</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20management" title=" project management"> project management</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20leadership" title=" strategic leadership"> strategic leadership</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20reduction" title=" waste reduction"> waste reduction</a> </p> <a href="https://publications.waset.org/abstracts/180731/strategic-leadership-and-sustainable-project-management-in-enugu-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180731.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">50</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> Oil Exploration in the Niger Delta and the Right to a Healthy Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olufunke%20Ayilara%20Aje-Famuyide">Olufunke Ayilara Aje-Famuyide</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The centrality of the Petroleum Industry in the world energy is undoubted. The world economy almost runs and depends on petroleum. Petroleum industry is a multi-trillion industry; it turns otherwise poor and underdeveloped countries into wealthy nations and thrusts them at the center of international diplomacy. Although these developing nations lack the necessary technology to explore and exploit petroleum resources they are not without help as developed nations, represented by their multinational corporations are ready and willing to provide both the technical and managerial expertise necessary for the development of this natural resource. However, the exploration of these petroleum resources comes with, sometimes, grave, concomitant consequences. These consequences are especially pronounced with respect to the environment. From the British Petroleum Oil rig explosion and the resultant oil spillage and pollution in New Mexico, United States to the Mobil Oil spillage along Nigerian coast, the story and consequence is virtually the same. Nigeria’s Niger Delta Region produces Nigeria’s petroleum which accounts for more than ninety-five percent of Nigeria’s foreign exchange earnings. Between 1999 and 2007, Nigeria earned more than $400 billion from petroleum exports. Nevertheless, petroleum exploration and exploitation has devastated the Niger Delta environment. From oil spillage which pollutes the rivers, farms and wetlands to gas flaring by the multi-national corporations; the consequences is similar-a region that has been devastated by petroleum exploitation. This paper thus seeks to examine the consequences and impact of petroleum pollution in the Niger Delta of Nigeria with particular reference on the right of the people of Niger Delta to a healthy environment. The paper further seeks to examine the relevant international, regional instrument and Nigeria’s municipal laws that are meant to protect the result of the people of the Niger Delta and their enforcement by the Nigerian State. It is quite worrisome that the Niger Delta Region and its people have suffered and are still suffering grave violations of their right to a healthy environment as a result of petroleum exploitation in their region. The Nigerian effort at best is half-hearted in its protection of the people’s right. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environment" title="environment">environment</a>, <a href="https://publications.waset.org/abstracts/search?q=exploration" title=" exploration"> exploration</a>, <a href="https://publications.waset.org/abstracts/search?q=petroleum" title=" petroleum"> petroleum</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution "> pollution </a> </p> <a href="https://publications.waset.org/abstracts/27314/oil-exploration-in-the-niger-delta-and-the-right-to-a-healthy-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27314.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">432</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> Detection and Dissemination of Putative Virulence Genes from Brucella Species Isolated from Livestock in Eastern Cape Province of South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rudzani%20Manafe">Rudzani Manafe</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezekiel%20Green"> Ezekiel Green </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brucella, has many different virulence factors that act as a causative agent of brucellosis, depending on the environment and other factors, some factors may play a role more than others during infection and as a result, play a role in becoming a causative agent for pathogenesis. Brucella melitensis and Brucella abortus are considered to be pathogenic to humans. The genetic regularity of nine potential causes of virulence of two Brucella species in Eastern Cape livestock have been examined. A hundred and twenty isolates obtained from Molecular Pathogenesis and Molecular Epidemiology Research Group (MPMERG) were used for this study. All isolates were grown on Brucella agar medium. Nine primer pairs were used for the detection of virB2, virB5, vceC, btpA, btpB, prpA, betB, bpe275, and bspB virulence factors using Polymerase chain reaction (PCR). Approximately 100% was observed for genes BecC and BetB from B. arbotus. While the lowest gene observed was PrpA at 4.6% from B. arbotus. BetB was detected in 34.7%, while virB2 and prpA (0%) were not detected in B. melitensis. The results from this research suggest that most isolates of Brucella have virulence-related genes associated with disease pathogenesis. Finally, our findings showed that Brucella strains in the Eastern Cape Province are extremely virulent as virulence characteristics exist in most strains investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=putative%20virulence%20genes" title="putative virulence genes">putative virulence genes</a>, <a href="https://publications.waset.org/abstracts/search?q=brucella" title=" brucella"> brucella</a>, <a href="https://publications.waset.org/abstracts/search?q=polymerase%20chain%20reaction" title=" polymerase chain reaction"> polymerase chain reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=milk" title=" milk"> milk</a> </p> <a href="https://publications.waset.org/abstracts/129066/detection-and-dissemination-of-putative-virulence-genes-from-brucella-species-isolated-from-livestock-in-eastern-cape-province-of-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129066.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">139</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> Analysis of Basic Science Curriculum as Correlates of Secondary School Students' Achievement in Science Test in Oyo State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olubiyi%20Johnson%20Ezekiel">Olubiyi Johnson Ezekiel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Basic science curriculum is an on-going effort towards developing the potential of manner to produce individuals in a holistic and integrated person, who are intellectually, spiritually, emotionally and physically balanced and harmonious. The main focus of this study is to determine the relationship between students’ achievement in junior school certificate examination (JSCE) and senior school basic science achievement test (SSBSAT) on the basis of all the components of basic science. The study employed the descriptive research of the survey type and utilized junior school certificate examination and senior school basic science achievement test(r = .87) scores as instruments. The data collected were subjected to Pearson product moment correlation, Spearman rank correlation, regression analysis and analysis of variance. The result of the finding revealed that the mean effects of the achievement in all the components of basic science on SSBSAT are significantly different from zero. Based on the results of the findings, it was concluded that the relationship between students’ achievement in JSCE and SSBSAT was weak and to achieve a unit increase in the students’ achievement in the SSBSAT when other subjects are held constant, we have to increase the learning of: -physics by 0.081 units; -chemistry by 0.072 units; -biology by 0.025 units and general knowledge by 0.097 units. It was recommended among others, that general knowledge aspect of basic science should be included in either physics or chemistry aspect of basic science. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basic%20science%20curriculum" title="basic science curriculum">basic science curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=students%E2%80%99%20achievement" title=" students’ achievement"> students’ achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20test" title=" science test"> science test</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20school%20students" title=" secondary school students"> secondary school students</a> </p> <a href="https://publications.waset.org/abstracts/70866/analysis-of-basic-science-curriculum-as-correlates-of-secondary-school-students-achievement-in-science-test-in-oyo-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70866.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">450</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> Heightening Pre-Service Teachers’ Attitude towards Learning and Metacognitive Learning through Information and Communication Technology: Pre-Service Science Teachers’ Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina">Abiodun Ezekiel Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ijeoma%20Ginikanwa%20Akubugwo"> Ijeoma Ginikanwa Akubugwo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Information and Communication Technology, ICT can heighten pre-service teachers’ attitudes toward learning and metacognitive learning; however, there is a dearth of literature on the perception of the pre-service teachers on heightening their attitude toward learning and metacognitive learning. Thus, this study investigates the perception of pre-service science teachers on heightening their attitude towards learning and metacognitive learning through ICT. Two research questions and four hypotheses guided the research. A mixed methods research was adopted for the study in concurrent triangulation type of integrating qualitative and quantitative approaches to the study. The cluster random sampling technique was adopted to select 250 pre-service science teachers in Oyo township. Two self-constructed instruments: Heightening Pre-service Science Teachers’ Attitude towards Learning and Metacognitive Learning through Information and Communication Technology Scale (HPALMIS, r=.73), and an unstructured interview were used for data collection. Thematic analysis, frequency counts and percentages, t-tests, and analysis of variance were used for data analysis. The perception level of the pre-service science teachers on heightening their attitude towards learning and metacognitive learning through ICT is above average, with the majority perceiving that ICT can enhance their thinking about their learning. The perception was significant (mean=92.68, SD=10.86, df=249, t=134.91, p<.05). The perception was significantly differentiated by gender (t=2.10, df= 248, p<.05) in favour of the female pre-service teachers and based on the first time of ICTs use (F(5,244)= 9.586, p<.05). Lecturers of science and science related courses should therefore imbibe the use of ICTs in heightening pre-service teachers’ attitude towards learning and metacognitive learning. Government should organize workshops, seminars, lectures, and symposia along with professional bodies for the science education lecturers to keep abreast of the trending ICT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-service%20teachers%E2%80%99%20attitude%20towards%20learning" title="pre-service teachers’ attitude towards learning">pre-service teachers’ attitude towards learning</a>, <a href="https://publications.waset.org/abstracts/search?q=metacognitive%20learning" title=" metacognitive learning"> metacognitive learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ICT" title=" ICT"> ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-service%20teachers%E2%80%99%20perspectives" title=" pre-service teachers’ perspectives"> pre-service teachers’ perspectives</a> </p> <a href="https://publications.waset.org/abstracts/154897/heightening-pre-service-teachers-attitude-towards-learning-and-metacognitive-learning-through-information-and-communication-technology-pre-service-science-teachers-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154897.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">101</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Fatty Acid Profile and Dietary Fibre Contents of Some Standardized Soups and Dishes Consumed in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olufunke%20O.%20Obanla">Olufunke O.

Accurate nutrient composition data for composite dishes unique to a population is essential for the development of a nutrient database and the calculation of dietary intake. Methods: Representative samples of standardized Nigerian soups and dishes were analyzed for fatty acids using gas chromatography-mass spectrophotometry (GC-MS) and dietary fibre using an enzymatic-gravimetric standard method of AOAC. Results: The total Saturated Fatty acids (SFAs) ranged from 0.74+0.3g/100g to 73.82+0.07g/100g. The total monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) ranged from 2.16+1.13g/100g for Yam pottage to 22.25+0.58g/100g for Okazi soup and eba, and from 0.42+0.10g/100g for Yam pottage to 10.22+0.1g/100g for Pounded yam with egusi ball soup, respectively. Trans fat was observed in Alapafubu and Tuwo shinkafa (2.80+0.2g/100g), Yam pottage (0.20+0.15g/100g), Steamed bean pudding (1.28+0.53g/100g) and Ikokore (5.33+0.41g/100g). The Total Dietary Fibre (TDF) contents of the dishes ranged from 12.95+2.99g/100g in Jollof rice to 62.00+0.94g/100g in Melon seed and vegetable soup, the Soluble Dietary Fibre (SDF) ranged from 2.05+0.32g/100g in Steamed bean pudding to 7.81+0.74g/100g in Ikokore while the Insoluble Dietary Fibre (IDF) ranged from 8.20+0.43g/100g in Jollof rice to 57.91+4.69g/100g in melon seed and vegetable soup. Conclusions: The study has indicated that some Nigerian dishes are characterized by high SFAs, TFAs and dietary fibre, moderate MUFAs and very low levels of PUFAs. High levels of SFAs in some soups and dishes are a major public health concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthy%20diet" title="healthy diet">healthy diet</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20fibre" title=" dietary fibre"> dietary fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acid%20profile" title=" fatty acid profile"> fatty acid profile</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20diseases" title=" chronic diseases"> chronic diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigerian%20dishes" title=" Nigerian dishes "> Nigerian dishes </a> </p> <a href="https://publications.waset.org/abstracts/40030/fatty-acid-profile-and-dietary-fibre-contents-of-some-standardized-soups-and-dishes-consumed-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40030.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">375</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> Computer Assisted Instructions for a Better Achievement in and Attitude towards Agricultural Economics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina">Abiodun Ezekiel Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Alice%20M.%20Olagunju"> Alice M.

Two hundred and thirty-two intact 200 level Agricultural education students offering introduction to AE course across the six CoE were participants. The participants were assigned to three groups (D&PM, 77, TM, 73 and control, 82). Treatment lasted eight weeks. The AE achievement test (r=0.76), pre-service teachers’ ASC Scale (r=0.81); instructional guides for tutorial (r=0.76), drill and practice (r=0.81) and conventional lecture modes (r=0.83), and teacher performance assessment sheet were used for data collection. Data were analysed using analysis of covariance and Scheffe post-hoc at 0.05 level of significance. The participants were 55.6% female with mean age of 20.8 years. Treatment had significant main effects on pre-service teachers’ achievement (F(2,207)=60.52; η²=0.21; p < 0.05). Participants in D&PM (x̄ =27.83) had the best achievement compared to those in TM (x̄ =25.41) and control (x̄ =18.64) groups. ASC had significant main effect on pre-service teachers’ achievement (F(1,207)=22.011; η²=0.166; p < 0.05). Participants with high ASC (x̄ =27.52) had better achievement compared to those with low ASC (x̄ =22.37). The drill and practice and tutorial instructional modes enhanced students’ achievement in Agricultural Economics concepts. Therefore, the two instructional modes should be adopted for improved learning outcomes in agricultural economics concepts among pre-service teachers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=achievement%20in%20agricultural%20economics%20concepts" title="achievement in agricultural economics concepts">achievement in agricultural economics concepts</a>, <a href="https://publications.waset.org/abstracts/search?q=colleges%20of%20education%20in%20southwestern%20Nigeria" title=" colleges of education in southwestern Nigeria"> colleges of education in southwestern Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=computer-assisted%20instruction" title=" computer-assisted instruction"> computer-assisted instruction</a>, <a href="https://publications.waset.org/abstracts/search?q=drill%20and%20practice%20instructional%20mode" title=" drill and practice instructional mode"> drill and practice instructional mode</a>, <a href="https://publications.waset.org/abstracts/search?q=tutorial%20instructional%20mode" title=" tutorial instructional mode"> tutorial instructional mode</a> </p> <a href="https://publications.waset.org/abstracts/84206/computer-assisted-instructions-for-a-better-achievement-in-and-attitude-towards-agricultural-economics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84206.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">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Risk Variables and Implications in Nigeria of Publicly Funded Construction Works Cessation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nnadi%20Ezekiel%20Oluwaseun%20Ejiofor">Nnadi Ezekiel Oluwaseun Ejiofor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The foundation of this study is the identification of risk variables and their implications on abandoned construction projects in Nigeria. The study's particular goals are to pinpoint the risk factors that lead to the abandonment of public building projects in Nigeria. This study used a hybrid research design that included case studies and descriptive survey research methods. Professionals who work directly in the built environment and are employed by Ministries and Departmental Agencies (MDAs), the public sector, or the private sector are the study's target demographic. This study used a descriptive survey and case study research design to gather data. Nigeria is experiencing a high rate of project abandonment due to housing deficit issues. Factors contributing to this include The study reveals factors contributing to public project abandonment in Abuja FCT include poor cashflow 4.96, inconsistent government policies 4.89, lack of accountability, high corruption, incompetent contractors, non-availability of building materials, lack of utilities, wrong materials, infrastructural facilities, poor planning, and undefined contracts. The study reveals that abandoned projects have a huge impact on the construction industry, such as wastage of resources with a mean value of 3.35, distrust of economic growth, 3.28, and so on. The study found a significant relationship between risk factors and public building construction in Abuja through a T-test value of 0.037, rejecting the null hypothesis and indicating a positive correlation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost" title="cost">cost</a>, <a href="https://publications.waset.org/abstracts/search?q=tetfund" title=" tetfund"> tetfund</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20projects" title=" construction projects"> construction projects</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20university" title=" public university"> public university</a> </p> <a href="https://publications.waset.org/abstracts/182432/risk-variables-and-implications-in-nigeria-of-publicly-funded-construction-works-cessation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182432.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">58</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Impacts of Computer Assisted Instruction and Gender on High-Flyers Pre-Service Teachers' Attitude towards Agricultural Economics in Southwest Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alice%20Morenike%20Olagunju">Alice Morenike Olagunju</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufemi%20A.%20Fakolade"> Olufemi A.

Not only large but even small construction projects contribute to a country’s economic growth. There is a need for good management to ensure successful delivery and sustainability because of the plethora of risks that have resulted in low-profit margins for contractors, cost and schedule overruns, poor quality delivery, and abandoned projects. This research reviewed Capitalization on Sustainable Risk Management. Questionnaires and oral interviews conducted were utilized as means of data collection. One hundred and ninety-eight (198) large construction firms in Nigeria form the population of this study. 15 (fifteen) companies that emanated from merger and acquisition were used for the study. The instruments used for data collection were a researcher-developed structured questionnaire based on a five-point rating scale, interviews, focus group discussion, and secondary sources (bill of quantities and stock and exchange commission). The instrument was validated by two experts in the field. The reliability of the instrument was established by applying the split-half method. Kendall’s coefficient of concordance was used to test the data, and a degree of agreement was obtained. Data were subjected to descriptive statistics and analyzed using analysis of variance, t-test, and SPSS. The identified impacts of capitalization were an increase in turnover (24.5%), improvement in the image (24.5%), risk reduction (20%), business expansion (17.3%), and geographical spread (13.6%). The study strongly advocates the inclusion of risk management evaluation as part of the construction procurement process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capitalization" title="capitalization">capitalization</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20delivery" title=" project delivery"> project delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=risks" title=" risks"> risks</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/180742/review-of-capitalization-of-construction-industry-on-sustainable-risk-management-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180742.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">61</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">13</span> Efficacy of Computer Mediated Power Point Presentations on Students' Learning Outcomes in Basic Science in Oyo State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunmaila%20Oyetunji%20Raimi">Sunmaila Oyetunji Raimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufemi%20Akinloye%20Bolaji"> Olufemi Akinloye Bolaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina"> Abiodun Ezekiel Adesina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The lingering poor performance of students in basic science spells doom for a vibrant scientific and technological development which pivoted the economic, social and physical upliftment of any nation. This calls for identifying appropriate strategies for imparting basic science knowledge and attitudes to the teaming youths in secondary schools. This study, therefore, determined the impact of computer mediated power point presentations on students’ achievement in basic science in Oyo State, Nigeria. A pre-test, posttest, control group quazi-experimental design adopted for the study. Two hundred and five junior secondary two students selected using stratified random sampling technique participated in the study. Three research questions and three hypotheses guided the study. Two evaluative instruments – Students’ Basic Science Attitudes Scale (SBSAS, r = 0.91); Students’ Knowledge of Basic Science Test (SKBST, r = 0.82) were used for data collection. Descriptive statistics of mean, standard deviation and inferential statistics of ANCOVA, scheffe post-hoc test were used to analyse the data. The results indicated significant main effect of treatment on students cognitive (F(1,200)= 171.680; p < 0.05) and attitudinal (F(1,200)= 34.466; p < 0.05) achievement in Basic science with the experimental group having higher mean gain than the control group. Gender has significant main effect (F(1,200)= 23.382; p < 0.05) on students cognitive outcomes but not significant for attitudinal achievement in Basic science. The study therefore recommended among others that computer mediated power point presentations should be incorporated into curriculum methodology of Basic science in secondary schools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basic%20science" title="basic science">basic science</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20mediated%20power%20point%20presentations" title=" computer mediated power point presentations"> computer mediated power point presentations</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=students%E2%80%99%20achievement" title=" students’ achievement"> students’ achievement</a> </p> <a href="https://publications.waset.org/abstracts/27999/efficacy-of-computer-mediated-power-point-presentations-on-students-learning-outcomes-in-basic-science-in-oyo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27999.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">429</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Efficacy of Teachers' Cluster Meetings on Teachers' Lesson Note Preparation and Teaching Performance in Oyo State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Joseph%20Adesina">Olusola Joseph Adesina</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunmaila%20Oyetunji%20Raimi"> Sunmaila Oyetunji Raimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufemi%20Akinloye%20Bolaji"> Olufemi Akinloye Bolaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Abiodun%20Ezekiel%20Adesina"> Abiodun Ezekiel Adesina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of education and the standard of a nation cannot rise above the quality of the teacher (NPE, 2004). Efforts at improving the falling standard of education in the country call for the need-based assessment of the primary tier of education in Nigeria. It was revealed that the teachers’ standard of performance and pupils’ achievement was below average. Teachers’ cluster meeting intervention was therefore recommended as a step towards enhancing the teachers’ professional competency, efficient and effective proactive and interactive lesson presentation. The study thus determined the impact of the intervention on teachers’ professional performance (lesson note preparation and teaching performance) in Oyo State, Nigeria. The main and interaction effects of the gender of the teachers as moderator variable were also determined. Three null hypotheses guided the study. Pre-test, posttest control group quazi experimental design was adopted for the study. Three hundred intact classes from three hundred different schools were randomly selected into treatment and control groups. Two response instruments-Classroom Lesson Note Preparation Checklist (CLNPC; r = 0.89) Cluster Lesson Observation Checklist (CLOC; r = 0.86) were used for data collection. Mean, Standard deviation and Analysis of Covariance (ANCOVA) were used to analyse the collected data. The results showed that the teachers’ cluster meeting have significant impact on teachers’ lesson note preparation (F(1,295) = 31.607; p < 0.05; η2 = .097) and teaching performance (F(1,295) = 20.849; p < 0.05; η2 = .066) in the core subjects of primary schools in Oyo State, Nigeria. The study therefore recommended among others that teachers’ cluster meeting should be sustained for teachers’ professional development in the State. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teachers%E2%80%99%20cluster%20meeting" title="teachers’ cluster meeting">teachers’ cluster meeting</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20lesson%20note%20preparation" title=" teacher lesson note preparation"> teacher lesson note preparation</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20performance" title=" teaching performance"> teaching performance</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%E2%80%99%20gender" title=" teachers’ gender"> teachers’ gender</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20schools%20in%20Oyo%20state" title=" primary schools in Oyo state"> primary schools in Oyo state</a> </p> <a href="https://publications.waset.org/abstracts/42091/efficacy-of-teachers-cluster-meetings-on-teachers-lesson-note-preparation-and-teaching-performance-in-oyo-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42091.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">345</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Effects of Neem (Azadirachta indica A.

The birds were randomly allotted to five dietary treatments, each treatment having four replicates consisting of five broilers in a completely randomized design. The diets were formulated to be iso-nitrogenous (23% CP). Weekly feed intake and changes in body weight were calculated and feed efficiency determined. At the end of the 28-day feeding trial, four broilers per treatment were selected and sacrificed for carcass evaluation. Results were subjected to statistical analysis using the analysis of variance procedures of Statistical Analysis Software The treatment means were presented with group standard errors of means and where significant, were compared using the Duncan multiple range test of the same software. The results showed that broilers fed 2.5% neem kernel inclusion diets had growth performance statistically comparable to those fed the control diet. Birds on 5, 7.5 and 10% neem kernel diets showed significant (P<0.05) increase in relative weight of liver. The absolute weight of spleen also increased significantly (P<0.05) in birds on 10 % neem kernel diet. More than 5 % neem kernel diets gave significant (P<0.05) increase in the relative weight of the kidney. The length of the small intestine significantly increased in birds fed 7.5 and 10% neem kernel diets. Significant differences (P<0.05) did not occur in the length of the large intestine, right and left caeca. It is recommended that neem kernel can be included up to 2.5% in broiler chicken diet without any deleterious effects on the performance and physiological status of the birds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broiler%20chicken" title="broiler chicken">broiler chicken</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20performance" title=" growth performance"> growth performance</a>, <a href="https://publications.waset.org/abstracts/search?q=gut%20morphometry" title=" gut morphometry"> gut morphometry</a>, <a href="https://publications.waset.org/abstracts/search?q=neem%20kernel" title=" neem kernel"> neem kernel</a>, <a href="https://publications.waset.org/abstracts/search?q=organ%20weight" title=" organ weight"> organ weight</a> </p> <a href="https://publications.waset.org/abstracts/18353/effects-of-neem-azadirachta-indica-a-juss-kernel-inclusion-in-broiler-diet-on-growth-performance-organ-weight-and-gut-morphometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18353.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">764</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">10</span> Lessons Learned from Push-Plus Implementation in Northern Nigeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Giwa">Aisha Giwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed-Faosy%20Adeniran"> Mohammed-Faosy Adeniran</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufunke%20Femi-Ojo"> Olufunke Femi-Ojo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Four decades ago, the World Health Organization (WHO) launched the Expanded Programme on Immunization (EPI). The EPI blueprint laid out the technical and managerial functions necessary to routinely vaccinate children with a limited number of vaccines, providing protection against diphtheria, tetanus, whooping cough, measles, polio, and tuberculosis, and to prevent maternal and neonatal tetanus by vaccinating women of childbearing age with tetanus toxoid. Despite global efforts, the Routine Immunization (RI) coverage in two of the World Health Organization (WHO) regions; the African Region and the South-East Asia Region, still remains short of its targets. As a result, the WHO Regional Director for Africa declared 2012 as the year for intensifying RI in these regions and this also coincided with the declaration of polio as a programmatic emergency by the WHO Executive Board. In order to intensify routine immunization, the National Routine Immunization Strategic Plan (2013-2015) stated that its core priority is to ensure 100% adequacy and availability of vaccines for safe immunization. To achieve 100% availability, the “PUSH System” and then “Push-Plus” were adopted for vaccine distribution, which replaced the inefficient “PULL” method. The NPHCDA plays the key role in coordinating activities in area advocacy, capacity building, engagement of 3PL for the state as well as monitoring and evaluation of the vaccine delivery process. eHealth Africa (eHA) is a player as a 3PL service provider engaged by State Primary Health Care Boards (SPHCDB) to ensure vaccine availability through Vaccine Direct Delivery (VDD) project which is essential to successful routine immunization services. The VDD project ensures the availability and adequate supply of high-quality vaccines and immunization-related materials to last-mile facilities. eHA’s commitment to the VDD project saw the need for an assessment of the project vis-a-vis the overall project performance, evaluation of a process for necessary improvement suggestions as well as general impact across Kano State (Where eHA had transitioned to the state), Bauchi State (currently manage delivery to all LGAs except 3 LGAs currently being managed by the state), Sokoto State (eHA currently covers all LGAs) and Zamfara State (Currently, in-sourced and managed solely by the state). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20chain%20logistics" title="cold chain logistics">cold chain logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20supply%20chain%20system%20strengthening" title=" health supply chain system strengthening"> health supply chain system strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=logistics%20management%20information%20system" title=" logistics management information system"> logistics management information system</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine%20delivery%20traceability%20and%20accountability" title=" vaccine delivery traceability and accountability"> vaccine delivery traceability and accountability</a> </p> <a href="https://publications.waset.org/abstracts/127335/lessons-learned-from-push-plus-implementation-in-northern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127335.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">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Involvement of Nrf2 in Kolaviron-Mediated Attenuation of Behavioural Incompetence and Neurodegeneration in a Murine Model of Parkinson's Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20E.%20Mustapha">Yusuf E.

Available therapies are palliative with no effect on disease progression. Kolaviron (KV), a natural anti-inflammatory and antioxidant agent, has been reported to possess neuroprotective effects in Parkinsonian flies and rats. Objective: The present study investigates the neuroprotective effect of KV, focusing on the DJ1/Nrf2 signaling pathway. Methodology: All-trans retinoic acid (ATRA, 10 mg/kg, i.p.) was used to inhibit Nrf2. Murine model of PD was established with four doses of MPTP (20 mg/kg i.p.) at 2 hours interval. MPTP mice were pre-treated with either KV (200 mg/kg/day p.o), ATRA, or both conditions for seven days before PD induction. Motor behaviour was evaluated, and markers of oxidative stress/damage and its regulators were assessed with immunofluorescence and ELISA techniques. Results: MPTP-treated mice covered less distance with reduced numbers of anticlockwise rotations, heightened freezing, and prolonged immobility when compared to control. However, KV significantly attenuated these deficits. Pretreatment of MPTP mice with KV upregulated Nrf2 expression beyond MPTP level with a remarkable reduction in Keap1 expression and marked elevation of DJ-1 level, whereas co-administration with ATRA abrogated these effects. KV treatment restored MPTP-mediated depletion of endogenous antioxidant, striatal oxidative stress, oxidative damage, and inhibition of acetylcholinesterase activity. However, ATRA treatment potentiated acetylcholinesterase inhibition and attenuated the protective effect of KV on the level of nitric oxide and activities of catalase and superoxide dismutase. Conclusion: Kolaviron protects Parkinsonian mice by stabilizing and activating the Nrf2 signaling pathway. Thus, kolaviron can be explored as a pharmacological lead in PD management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Garcinia%20kola"
