concentration of toxic components in combustion products and decreasing fossil fuel consumption by using renewable alternative fuels. In this work, the impact of ethanol-gasoline blend on the exhaust emission of a single cylinder non-mobile spark ignition engine was investigated. Gasoline was blended with 5 – 20% of ethanol sourced from the open market (bought off the shelf) in an interval of 5%. The results of the emission characteristics of the exhaust gas from the combustion of the ethanol-gasoline blends showed that increasing the percentage of ethanol in the blend decreased CO emission by between 2.12% and 52.29% and HC emissions by between12.14% and 53.24%, but increased CO2 and NOx emissions by between 25% to 56% and 59% to 60% respectively. E15 blend is preferred above other blends at no-load and across all the load variations. However its NOx emission was the highest when compared with other samples. This will negatively affect human health and the environment but this drawback can be remedied by adequate treatment with appropriate additives. <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=emission" title=" emission"> emission</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=gasoline" title=" gasoline"> gasoline</a>, <a href="https://publications.waset.org/abstracts/search?q=spark%20ignition%20engine" title=" spark ignition engine"> spark ignition engine</a> </p> <a href="https://publications.waset.org/abstracts/76628/the-analysis-of-exhaust-emission-from-single-cylinder-non-mobile-spark-ignition-engine-using-ethanol-gasoline-blend-as-fuel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76628.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">197</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> 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">37</span> Leveraging Remote Sensing Information for Drought Disaster Risk Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Israel%20Ropo%20Orimoloye">Israel Ropo Orimoloye</a>, <a href="https://publications.waset.org/abstracts/search?q=Johanes%20A.%20Belle"> Johanes A.

With Terra instrument's performance and the free distribution of its products, this study utilised Terra MOD13Q1 satellite data to assess drought disaster events and its spatiotemporal patterns over the Free State Province of South Africa between 2001 and 2019 for summer, autumn, winter, and spring seasons. The study also used high-resolution downscaled climate change projections under three representative concentration pathways (RCP). Three future periods comprising the short (the 2030s), medium (2040s), and long term (2050s) compared to the current period are analysed to understand the potential magnitude of projected climate change-related drought. The study revealed that the year 2001 and 2016 witnessed extreme drought conditions where the drought index is between 0 and 20% across the entire province during summer, while the year 2003, 2004, 2007, and 2015 observed severe drought conditions across the region with variation from one part to the another. The result shows that from -24.5 to -25.5 latitude, the area witnessed a decrease in precipitation (80 to 120mm) across the time slice and an increase in the latitude -26° to -28° S for summer seasons, which is more prominent in the year 2041 to 2050. This study emphasizes the strong spatio-environmental impacts within the province and highlights the associated factors that characterise high drought stress risk, especially on the environment and ecosystems. This study contributes to a disaster risk framework to identify areas for specific research and adaptation activities on drought disaster risk and for environmental planning in the study area, which is characterised by both rural and urban contexts, to address climate change-related drought impacts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title="remote sensing">remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=drought%20disaster" title=" drought disaster"> drought disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20scenario" title=" climate scenario"> climate scenario</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a> </p> <a href="https://publications.waset.org/abstracts/131504/leveraging-remote-sensing-information-for-drought-disaster-risk-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131504.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">187</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> Optimization of Solar Chimney Power Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Bamisile">Olusola Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwaseun%20Ayodele"> Oluwaseun Ayodele</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi"> Mustafa Dagbasi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this research is to optimize the power produced by a solar chimney wind turbine.

Despite this, there are lots of resources that are being expended on the correct prediction of soccer matches weekly, and all over the world. Soccer Match Result Prediction System Model (SMRPSM) is a system that is proposed whereby the results of matches between two soccer teams are auto-generated, with the added excitement of giving users a chance to test their predictive abilities. Soccer teams from different league football are loaded by the application, with each team’s corresponding manager and other information like team location, team logo and nickname. The user is also allowed to interact with the system by selecting the match to be predicted and viewing of the results of completed matches after registering/logging in. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predicting" title="predicting">predicting</a>, <a href="https://publications.waset.org/abstracts/search?q=soccer%20match" title=" soccer match"> soccer match</a>, <a href="https://publications.waset.org/abstracts/search?q=outcome" title=" outcome"> outcome</a>, <a href="https://publications.waset.org/abstracts/search?q=soccer" title=" soccer"> soccer</a>, <a href="https://publications.waset.org/abstracts/search?q=matches" title=" matches"> matches</a>, <a href="https://publications.waset.org/abstracts/search?q=result%20prediction" title=" result prediction"> result prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=system" title=" system"> system</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a> </p> <a href="https://publications.waset.org/abstracts/15730/soccer-match-result-prediction-system-smrps-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15730.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">491</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> Proposed Fault Detection Scheme on Low Voltage Distribution Feeders</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adewusi%20Adeoluwawale">Adewusi Adeoluwawale</a>, <a href="https://publications.waset.org/abstracts/search?q=Oronti%20Iyabosola%20Busola"> Oronti Iyabosola Busola</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinola%20Iretiayo"> Akinola Iretiayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Komolafe%20Olusola%20Aderibigbe"> Komolafe Olusola Aderibigbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The complex and radial structure of the low voltage distribution network (415V) makes it vulnerable to faults which are due to system and the environmental related factors. Besides these, the protective scheme employed on the low voltage network which is the fuse cannot be monitored remotely such that in the event of sustained fault, the utility will have to rely solely on the complaint brought by customers for loss of supply and this tends to increase the length of outages. A microcontroller based fault detection scheme is hereby developed to detect low voltage and high voltage fault conditions which are common faults on this network. Voltages below 198V and above 242V on the distribution feeders are classified and detected as low voltage and high voltages respectively. Results shows that the developed scheme produced a good response time in the detection of these faults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20detection" title="fault detection">fault detection</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20voltage%20distribution%20feeders" title=" low voltage distribution feeders"> low voltage distribution feeders</a>, <a href="https://publications.waset.org/abstracts/search?q=outage%20times" title=" outage times"> outage times</a>, <a href="https://publications.waset.org/abstracts/search?q=sustained%20faults" title=" sustained faults"> sustained faults</a> </p> <a href="https://publications.waset.org/abstracts/8097/proposed-fault-detection-scheme-on-low-voltage-distribution-feeders" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8097.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">543</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> Bayesian Hidden Markov Modelling of Blood Type Distribution for COVID-19 Cases Using Poisson Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Johnson%20Joseph%20Kwabina%20Arhinful">Johnson Joseph Kwabina Arhinful</a>, <a href="https://publications.waset.org/abstracts/search?q=Owusu-Ansah%20Emmanuel%20Degraft%20Johnson"> Owusu-Ansah Emmanuel Degraft Johnson</a>, <a href="https://publications.waset.org/abstracts/search?q=Okyere%20Gabrial%20Asare"> Okyere Gabrial Asare</a>, <a href="https://publications.waset.org/abstracts/search?q=Adebanji%20Atinuke%20Olusola"> Adebanji Atinuke Olusola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a model to describe the blood types distribution of new Coronavirus (COVID-19) cases using the Bayesian Poisson - Hidden Markov Model (BP-HMM).

Two hundred (200) in-school adolescents were purposely selected in Afijio Local Government Area of Oyo State. Two hypotheses were also raised to pilot the study. The researchers developed an instrument which was validated by psychological experts, the instrument tagged counseling psychology and sexual risk behavior questionnaire (CPSRBQ)(r = 0.78). The results were analysed using t-test at 0.05 level of significance. The result showed that there is a significant relationship between counseling psychology and sexual risk behavior of in-school adolescents. It was also noticed that there is a significant difference in the sexual risk behavior of male and female adolescents. Based on the findings, it was recommended that more counselors are still needed in Nigeria schools. There is need for restructuring Nigeria Curriculum most especially on sex education and related diseases. Lastly, adolescents should be more exposed to seminars on HIV/AIDS, sex education enlightenment programmes and marital counseling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=counseling%20psychology" title="counseling psychology">counseling psychology</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20behavior" title=" sexual behavior"> sexual behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20and%20adolescent" title=" risk and adolescent"> risk and adolescent</a>, <a href="https://publications.waset.org/abstracts/search?q=cognitive%20sciences" title=" cognitive sciences"> cognitive sciences</a> </p> <a href="https://publications.waset.org/abstracts/6773/predicting-the-effects-of-counseling-psychology-on-the-sexual-risk-behavior-of-in-school-adolescents-implication-for-national-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6773.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">508</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> Performance Analysis of Solar Assisted Air Condition Using Carbon Dioxide as Refrigerant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Bamisile">Olusola Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Ferdinard%20Dika"> Ferdinard Dika</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi"> Mustafa Dagbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Serkan%20Abbasoglu"> Serkan Abbasoglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to model an air conditioning system that brings about effective cooling and reduce fossil fuel consumption with solar energy as an alternative source of energy. The objective of the study is to design a system with high COP, low usage of electricity and to integrate solar energy into AC systems. A hybrid solar assisted air conditioning system is designed to produce 30kW cooling capacity and R744 (CO₂) is used as a refrigerant. The effect of discharge pressure on the performance of the system is studied. The subcool temperature, evaporating temperature (5°C) and suction gas return temperature (12°C) are kept constant for the four different discharge pressures considered. The cooling gas temperature is set at 25°C, and the discharge pressure includes 80, 85, 90 and 95 bars. Copeland Scroll software is used for the simulation. A pressure-enthalpy graph is also used to deduce each enthalpy point while numerical methods were used in making other calculations. From the result of the study, it is observed that a higher COP is achieved with the use of solar assisted systems. As much as 46% of electricity requirements will be save using solar input at compressor stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20conditioning" title="air conditioning">air conditioning</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title=" energy saving"> energy saving</a> </p> <a href="https://publications.waset.org/abstracts/82514/performance-analysis-of-solar-assisted-air-condition-using-carbon-dioxide-as-refrigerant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82514.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Impact of Internal Control on Fraud Detection and Prevention: A Survey of Selected Organisations in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amos%20Olusola%20Akinola">Amos Olusola Akinola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate the internal control system on fraud prevention in Nigerian business organizations. A survey research was undertaken in five organizations from the banking and manufacturing sectors in Nigeria using the simple random sampling technique and primary data was obtained with the aid structured questionnaire drawn on five likert’s scale. Four Hypotheses were formulated and tested using the T-test Statistics, Correlation and Regression Analysis at 95% confidence interval. It was discovered that internal control has a significant positive relationship with fraud prevention and that a weak internal control system permits fraudulent activities among staff. Based on the findings, it was recommended that organizations should continually and methodically review and evaluate the components of its internal control system whether activities are working as planned or not and that every organization should have pre-determined guidelines for conducting its operations and ensures compliance with these set guidelines while proactive steps should be taken to establish the independence of the internal audit by making the audit reportable to the governing council of an organization and not the chief executive officer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20control" title="internal control">internal control</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20system" title=" internal system"> internal system</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20audit" title=" internal audit"> internal audit</a>, <a href="https://publications.waset.org/abstracts/search?q=fraud%20prevention" title=" fraud prevention"> fraud prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=fraud%20detection" title=" fraud detection"> fraud detection</a> </p> <a href="https://publications.waset.org/abstracts/40751/impact-of-internal-control-on-fraud-detection-and-prevention-a-survey-of-selected-organisations-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40751.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">24</span> Perceived Effect of Livelihood Diversification on the Welfare of Rural Households in Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oladipo%20Joseph%20Ajayi">Oladipo Joseph Ajayi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yakubu%20Muhammed"> Yakubu Muhammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Raufu%20Olusola%20Sanusi"> Raufu Olusola Sanusi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study determined the perceived effect of livelihood diversification on welfare of rural household in Niger state, Nigeria. Multi-stage sampling technique was adopted for sampling the respondents. Data used for the study were obtained from primary source. Structured questionnaire with interview schedule was administered to 180 randomly selected rural farmers in the study area. Descriptive statistics analysis and z-test statistics were used to analyse the data collected. The study revealed the mean age of the household to be 43 years, mean years of schooling was 8.5, mean household size was 6 people, mean farming experience of 17.5 years and mean farm size of 1.8 hectares. The effect of livelihood diversification revealed that livelihood diversification had positive and significant effect on food security (65.6%) and income generation (66.8%) in the study area. The major constraints to diversification in the study area were poor infrastructure, unavailability of credit and climatic risk and uncertainty. The study, therefore, recommended that rural household should be sensitised to diversify their income source into non-farm activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=income" title="income">income</a>, <a href="https://publications.waset.org/abstracts/search?q=livelihood%20diversification" title=" livelihood diversification "> livelihood diversification </a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20household" title=" rural household"> rural household</a>, <a href="https://publications.waset.org/abstracts/search?q=welfare" title=" welfare"> welfare</a> </p> <a href="https://publications.waset.org/abstracts/56111/perceived-effect-of-livelihood-diversification-on-the-welfare-of-rural-households-in-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56111.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">416</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> Effect of Varying Stocking Densities and Vitamin C (Ascorbic Acid) Supplementation on Growth Performance of Japanese Quails</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20S.%20Olugbemi">T.

Five hundred and twenty (520) unsexed quail birds of two (2) weeks of age were allotted randomly into nine (9) groups with 3 replicates each in a 3x3 factorial arrangement (3 stocking density levels and 3 graded vitamin C levels) with densities of 150, 120, 90 cm2/bird(11, 16, 21 birds). During the five weeks growing trial (2- 6 weeks), results showed that stocking density had significant effects on final weight (131.59g compared to 111.10g for the lowest), total and daily weight gain. No significance difference was observed for feed conversion ratio, age at first lay and first egg weight. Observations on haematological parameters (packed cell volume (PCV), total protein (TP), haemoglobin, red blood cell (RBC), lymphocyte, heterophil) on stocking density showed no significant differences. Vitamin C supplementation at 50mg/kg and 100mg/kg did not have any significant effect on the growth performance parameters of growing quails. Stocking density at 150cm2/bird had a better performance with or without vitamin C supplementation hence it is recommended that stocking rates of quails between the ages of 2 – 6 weeks should not be below 150cm2/bird. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-oxidants" title="anti-oxidants">anti-oxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=stress" title=" stress"> stress</a>, <a href="https://publications.waset.org/abstracts/search?q=stocking%20density" title=" stocking density"> stocking density</a> </p> <a href="https://publications.waset.org/abstracts/19499/effect-of-varying-stocking-densities-and-vitamin-c-ascorbic-acid-supplementation-on-growth-performance-of-japanese-quails" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19499.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">646</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> Allelopathic Effect of Duranta Repens on Salinity-Stressed Solanum Lycopersicum Seedlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Nafisat%20Omoniyi">Olusola Nafisat Omoniyi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aqueous extract of Duranta repens leaves was investigated for its allelopathic effect on Solanum lycopersicum Seedlings germinated and grown under salinity condition. The study was carried out using both laboratory petri dish and pot assays to simulate the plant’s natural environmental conditions. The experiment consisted of 5 groups (1-5), each containing 5 replicates (of 10 seeds). Group 1 was treated with distilled water; Group 2 was treated with 5 mM NaCl; Group 3 was treated with the Extract, Group 4 was treated with a mixture of 5 mM NaCl and the Extract (2:1 v/v), and Group 5 was treated with a mixture of 5 mM NaCl and the Extract (1:2 v/v). The results showed that treatment with NaCl caused significant reductions in germination, growth parameters (plumule and radicle lengths), and chlorophyll concentration of S. lycopersicum seedlings when compared to those treated with D. rupens aqueous leaf extract. Salinity also caused an increase in malondialdehyde and proline concentrations and lowered the activity of superoxide dismutase. However, in the presence of the extract, the adverse effects of the NaCl were attenuated, implying that the extract improved tolerance of S. lycopersicum seedlings. In conclusion, the findings of this study show that the extract is very important in the optimal growth of the plant in saline soil, which has become useful for the management of soil salinity problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=allelopathic" title=" allelopathic"> allelopathic</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthesis" title=" photosynthesis"> photosynthesis</a> </p> <a href="https://publications.waset.org/abstracts/114419/allelopathic-effect-of-duranta-repens-on-salinity-stressed-solanum-lycopersicum-seedlings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114419.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">219</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Athlete’s Preparation and Quality of Opponent as Determinants of Self-Efficacy among University Athletes in South-West Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raimi%20Abiodun%20Moronfolu">Raimi Abiodun Moronfolu</a>, <a href="https://publications.waset.org/abstracts/search?q=Anthonia%20Olusola%20Moronfolu"> Anthonia Olusola Moronfolu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to assess athlete’s preparation and quality of opponent as determinants of self-efficacy among university athletes in south-west Nigeria. The descriptive research method was employed in conducting the study. A total of 200 athletes, selected from 4 universities in South-West geopolitical zone of Nigeria through a stratified random sampling technique, were used in the study. The instrument used for data collection was a self-structured questionnaire named ‘Athletes Self-Efficacy Assessment Questionnaire (ASAQ)’.

This prompted both parties to enter into agreement with the notion to strengthening the relationship between them. The agreement was therefore entered into between NEHAWU representing the employees and the University. The agreement was signed on August 31st, 2005. The study adopting historical research method reveals the trend and implementation of bargaining agreements at University of Fort Hare from 2012 to 2016. This study examines how the implementation of bargaining agreement is utilized to solve labor related challenges and also improve on employee’s wages and conditions of service thereby strengthening the relationship between the management and employees at University of Fort Hare. The study contributes to knowledge on the effects of the implementation of bargaining agreement on wages and other conditions of service leading to harmonious relationship between the Staff and the management towards the effective administration of the University of Fort Hare. Findings reveal that ever since 2005 when the agreement was reached, University of Fort Hare and NEHAWU have been committed to improving the employees’ wages through substantive agreement. The study concludes by recommending a more effective implementation of bargaining agreement at University of Fort Hare. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agreement" title="agreement">agreement</a>, <a href="https://publications.waset.org/abstracts/search?q=bargaining" title=" bargaining"> bargaining</a>, <a href="https://publications.waset.org/abstracts/search?q=implementation" title=" implementation"> implementation</a>, <a href="https://publications.waset.org/abstracts/search?q=trend" title=" trend"> trend</a> </p> <a href="https://publications.waset.org/abstracts/70278/the-trend-and-implementation-of-bargaining-agreements-at-university-of-fort-hare-eastern-cape-south-africa-2012-to-2016" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70278.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">278</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> Exploring Challenges Faced by Small Business Owners on Poverty Reduction in Rural Eastern Cape, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akinwale%20Olusola%20Mokayode">Akinwale Olusola Mokayode</a>, <a href="https://publications.waset.org/abstracts/search?q=Emaanuel%20Adu"> Emaanuel Adu</a>, <a href="https://publications.waset.org/abstracts/search?q=Seriki%20Idowu%20Ibrahim"> Seriki Idowu Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Small business can serve as a tool for poverty reduction in South Africa, but it requires adequate support and development for its continuous sustenance in spite of rigorous challenges, especially in the rural environment. This study explored the challenges faced by the small business owners in the rural Eastern Cape Province of South Africa. The objective of the study is to identify the challenges faced by small business owners in the case study area and to examine the effects of those challenges on poverty rate. Survey research design was adopted, with the distribution of structured questionnaire for data collection through a simple random sampling method. Descriptive and inferential statistics was used to analyse the data. Findings showed that small business owners face various challenges in their commercial operations. It was also made clearer that these challenges have effects on the poverty rate as well as crime rate. In conclusion, in other for small businesses to be effective instrument to tackle poverty, certain measure must be taken into considerations. This therefore necessitates recommendation from the researcher that potential and current business owners must seek valuable advice from the more experienced business tycoon and seek information about the business assistance programmes provided by government and private sectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eastern%20cape" title="eastern cape">eastern cape</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty" title=" poverty"> poverty</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty%20reduction" title=" poverty reduction"> poverty reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=rural" title=" rural"> rural</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20business" title=" small business"> small business</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20livelihood" title=" sustainable livelihood"> sustainable livelihood</a> </p> <a href="https://publications.waset.org/abstracts/27842/exploring-challenges-faced-by-small-business-owners-on-poverty-reduction-in-rural-eastern-cape-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27842.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">488</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> 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.

A pretest, posttest, control group, quasi-experimental research design was adopted in the study. 17 participants (11 males and 6 females) were selected purposively from 5 centres in Ibadan and randomized into three groups (token economy, video modeling and control groups). Two instruments were used in the study; Autism Spectrum Rating Scale (ASRS) for 299.00 Autistic Disorder (r = 0.82) and Children’s Self-report Social Skill Scale (CS4) (r= 0.93). A descriptive statistics was used to analyse the participants social interaction data based on intervention and gender, while inferential statistics of analysis of covariance (ANCOVA) and scheffe post-hoc measure was used to anlayse three null hypotheses tested at 0.05 level of significance. The results obtained indicated that there was a significant main effect of treatment on social interaction of participants, but there was no significant of main effect of gender on the social interaction of participants, hence, (F(2,14) = .741; p > .05, eta = .050). Lastly, there was no significant interaction effect of treatment and gender of the participants, hence (F(2,10) = 2.177; p > .05, eta 2 = 202).

Diabetes was induced in albino rats by administration of STZ (65 mg/kg) intraperitoneally. Saponin (40 and 100 mg/kg) was administered by oral gavage once daily for 21 days. Metformin (200 mg/kg b.w.) was administered as the positive control. The effect of saponin on blood glucose, serum lipids and enzymatic antioxidants defense systems, like superoxide dismutase (SOD), catalase (CAT), as well as MDA levels in serum, liver and pancreas were studied. Saponins from S. anguivi fruits reduced the blood glucose, total cholesterol (TC), triglycerides (TG) and low-density lipoprotein (LDL) levels in STZ-diabetic rats. They also significantly abolished the increase in MDA level in serum, liver and pancreas of diabetic rats. The activities of SOD and CAT in serum, liver and pancreas were significantly increased as well as concentration of HDL in the serum. Metformin had the same effect as saponin but saponins seems to be more potent in reducing serum TC, TG, LDL, and MDA, and increasing SOD and CAT. Conclusions: These results suggest that saponins from S. anguivi fruits have anti-diabetic and antihypercholesterolemic, antihypertriglyceridemic antiperoxidative activities mediated through their antioxidant properties. Also, saponins appeared to have more hypolipidemic, antiperoxidative and antioxidant activity than metformin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saponin" title="saponin">saponin</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=metformin" title=" metformin"> metformin</a>, <a href="https://publications.waset.org/abstracts/search?q=streptozotocin" title=" streptozotocin"> streptozotocin</a>, <a href="https://publications.waset.org/abstracts/search?q=Solanum%20anguivi" title=" Solanum anguivi"> Solanum anguivi</a> </p> <a href="https://publications.waset.org/abstracts/20630/saponins-from-the-fruits-of-solanum-anguivi-reverse-hyperglycemia-hyperlipidemia-and-increase-antioxidant-status-in-stretozotocin-induced-diabetic-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20630.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">478</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">14</span> The Post-Colonial Yoruba Poets as Agents of Political and Economic Emancipation in Nigeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Alonge%20Olusola">Isaac Alonge Olusola</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the major peculiarities of man is the ability to communicate and interact with language. The original Yoruba society, before the advent of the Europeans, was purely oral. That is the major means of inter- personal communication was through speaking. The abolition of slave trade by Britain marked the beginning of development of Yoruba alphabet and introduction of writing around 1800. However, most of the writing was Christian religion-focused. Later, the introduction of British colonial rule led to the introduction of writing that dwelt on political and economic emancipation. On October 1, 1960, Nigeria was granted independence by the British colonial masters and self-rule started in Nigeria. Unfortunately, the military and civilian administrations brought about political and economic oppression instead of comfort. The discomfort brought about by Nigerian political and military rulers turned the Yoruba poets to activists, reactionaries and critics. This paper will give a brief preamble on the history of Nigeria and how she got her political independence from the British in 1960. It will thereafter go further to mention some political and economic hardship brought about by Nigerian leaders. Using literary theories called semiotics and structuralism, the reactions and criticisms of some Yoruba poets will be mentioned and analyzed vis-à-vis the counter reactions of the governments in power. Moreover, the paper will bring about a conclusion on how to create a conducive atmosphere for the Yoruba poets to operate in Nigeria. Finally, suggestions will be offered on how the Nigerian government and Yoruba poets can co-exist positively to bring about a better standard of living to Nigerians and also promote good governance <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yoruba" title="Yoruba">Yoruba</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoruba%20language" title=" Yoruba language"> Yoruba language</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoruba%20poets" title=" Yoruba poets"> Yoruba poets</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20leaders" title=" political leaders"> political leaders</a> </p> <a href="https://publications.waset.org/abstracts/117361/the-post-colonial-yoruba-poets-as-agents-of-political-and-economic-emancipation-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117361.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">13</span> Automated Distribution System Management: Substation Remote Diagnostic and Operation Solution for Obafemi Awolowo University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aderonke%20Oluseun%20Akinwumi">Aderonke Oluseun Akinwumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusola%20A.%20Komolaf"> Olusola A.

It also proffers cost-effective solution through remote monitoring, diagnostic and operation of distribution networks without compromising the system reliability. As utilities move from manned and unintelligent networks to completely unmanned smart grids, switching activities at substations and feeders will be managed and controlled remotely by dedicated systems hence this design. The Substation Remote Diagnostic and Operation Solution (sRDOs) would remotely monitor the load on Medium Voltage (MV) and Low Voltage (LV) feeders as well as distribution transformers and allow the utility disconnect non-paying customers with absolutely no extra resource deployment and without interrupting supply to paying customers. The aftermath of the implementation of this design improved the lifetime of key distribution infrastructure by automatically isolating feeders during overload conditions and more importantly erring consumers. This increased the ratio of revenue generated on electricity bills to total network load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20utility" title="electric utility">electric utility</a>, <a href="https://publications.waset.org/abstracts/search?q=consumers" title=" consumers"> consumers</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20monitoring" title=" remote monitoring"> remote monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnostic" title=" diagnostic"> diagnostic</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20reliability" title=" system reliability"> system reliability</a>, <a href="https://publications.waset.org/abstracts/search?q=manned%20and%20unintelligent%20networks" title=" manned and unintelligent networks"> manned and unintelligent networks</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20smart%20grids" title=" unmanned smart grids"> unmanned smart grids</a>, <a href="https://publications.waset.org/abstracts/search?q=switching%20activities" title=" switching activities"> switching activities</a>, <a href="https://publications.waset.org/abstracts/search?q=medium%20voltage" title=" medium voltage"> medium voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20voltage" title=" low voltage"> low voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution%20transformer" title=" distribution transformer"> distribution transformer</a> </p> <a href="https://publications.waset.org/abstracts/84884/automated-distribution-system-management-substation-remote-diagnostic-and-operation-solution-for-obafemi-awolowo-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84884.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">131</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> Phyllantus nuriri Protect against Fe2+ and SNP Induced Oxidative Damage in Mitochondrial Rich Fractions of Rats Brain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Olalekan%20Elekofehinti">Olusola Olalekan Elekofehinti</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaac%20Gbadura%20Adanlawo"> Isaac Gbadura Adanlawo</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Batista%20Teixeira%20Rocha"> Joao Batista Teixeira Rocha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We evaluated the potential neuroprotective effect of Phyllantus nuriri against Fe2+ and SNP induced oxidative stress in mitochondria of rats brain. Cellular viability was assessed by MTT reduction, reactive oxygen species (ROS) generation was measured using the probe 2,7-dichlorofluorescein diacetate (DCFH-DA). Glutathione content was measured using dithionitrobenzoic acid (DTNB). Fe2+ (10µM) and SNP (5µM) significantly decreased mitochondrial activity, assessed by MTT reduction assay, in a dose-dependent manner, this occurred in parallel with increased glutathione oxidation, ROS production and lipid peroxidation end-products (thiobarbituric acid reactive substances, TBARS). The co-incubation with methanolic extract of Phyllantus nuriri (10-100 µg/ml) reduced the disruption of mitochondrial activity, gluthathione oxidation, ROS production as well as the increase in TBARS levels caused by both Fe2+ and SNP in a dose dependent manner. HPLC analysis of the extract revealed the presence of gallic acid (20.54±0.01), caffeic acid (7.93±0.02), rutin (25.31±0.05), quercetin (31.28±0.03) and kaemferol (14.36±0.01). This result suggests that these phytochemicals account for the protective actions of Phyllantus nuriri against Fe2+ and SNP -induced oxidative stress. Our results show that Phyllantus nuriri consist important bioactive molecules in the search for an improved therapy against the deleterious effects of Fe2+, an intrinsic producer of reactive oxygen species (ROS), that leads to neuronal oxidative stress and neurodegeneration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Phyllantus%20niruri" title="Phyllantus niruri">Phyllantus niruri</a>, <a href="https://publications.waset.org/abstracts/search?q=neuroprotection" title=" neuroprotection"> neuroprotection</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=mitochondria" title=" mitochondria"> mitochondria</a>, <a href="https://publications.waset.org/abstracts/search?q=synaptosome" title=" synaptosome"> synaptosome</a> </p> <a href="https://publications.waset.org/abstracts/20633/phyllantus-nuriri-protect-against-fe2-and-snp-induced-oxidative-damage-in-mitochondrial-rich-fractions-of-rats-brain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20633.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">359</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> The Techno-Economic Comparison of Solar Power Generation Methods for Turkish Republic of North Cyprus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Dagbasi">Mustafa Dagbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusola%20Bamisile"> Olusola Bamisile</a>, <a href="https://publications.waset.org/abstracts/search?q=Adii%20Chinedum"> Adii Chinedum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this work is to examine and compare the economic and environmental feasibility of 40MW photovoltaic (PV) power plant and 40MW parabolic trough (PT) power plant to be installed in two different cities, namely Nicosia and Famagusta in Turkish Republic of Northern Cyprus (TRNC). The need for using solar power technology around the world is also emphasized. Solar radiation and sunshine data for Nicosia and Famagusta are considered and analyzed to assess the distribution of solar radiation, sunshine duration, and air temperature. Also, these two different technologies with same rated power of 40MW will be compared with the performance of the proposed Solar Power Plant at Bari, Italy. The project viability analysis is performed using System Advisor Model (SAM) through Annual Energy Production and economic parameters for both cities. It is found that for the two cities; Nicosia and Famagusta, the investment is feasible for both 40MW PV power plant and 40MW PT power plant. From the techno-economic analysis of these two different solar power technologies having same rated power and under the same environmental conditions, PT plants produce more energy than PV plant. It is also seen that if a PT plant is installed near an existing steam turbine power plant, the steam from the PT system can be used to run this turbine which makes it more feasible to invest. The high temperatures that are used to produce steam for the turbines in the PT plant system can be supplemented with a secondary plant based on natural gas or other biofuels and can be used as backup. Although the initial investment of PT plant is higher, it has higher economic return and occupies smaller area compared to PV plant of the same capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20power" title="solar power">solar power</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20plant" title=" photovoltaic plant"> photovoltaic plant</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20trough%20plant" title=" parabolic trough plant"> parabolic trough plant</a>, <a href="https://publications.waset.org/abstracts/search?q=techno-economic%20analysis" title=" techno-economic analysis"> techno-economic analysis</a> </p> <a href="https://publications.waset.org/abstracts/47894/the-techno-economic-comparison-of-solar-power-generation-methods-for-turkish-republic-of-north-cyprus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47894.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">283</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> 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
