This study evaluated the morpho-agronomic response of twenty-four (24) Nigerian Bambara groundnut landraces to water stress and genetic diversity of some selected accessions using SSR markers. The studies was carried out in the Botanical garden of the Department of Plant Biology, Federal University of Technology, Minna, Niger State, Nigeria in a randomized complete block design using three replicates. Molecular analysis using SSR primers was carried out at the Centre for Bio- Science, International Institute of Tropical Agriculture (IITA) Ibadan, Nigeria in order to characterize ten selected accessions comprising of the seven most drought tolerant and the three most susceptible accessions detected from the morpho-agronomic studies. Results revealed that water stress decreased morpho-agronomic traits such as plant height, leaf area, number of leaves per plant and seed yield etc. A total of 22 alleles were detected by the SSR markers used with a mean number of 4 allelles. Simple Sequence Repeat (SSR) markers MBamCO33, Primer 65 and G358B2-D15 each detected 4 allelles while Primer 3FR and 4FR detected 5 allelles each. The study revealed significantly high polymorphisms in 10 Loci. The mean value of Polymorpic information content was 0.6997 implying the usefulness of the primers used in identifying genetic similarities and differences among the Bambara groundnut genotypes. The SSR analysis revealed a comparable pattern between genetic diversity and drought tolerance of the genotypes. The Unweighted Paired Group Method with Arithmethic Mean (UPGMA) dendrogram showed that at a genetic distance of 0.1, the accessions were grouped into three groups according to their level of tolerance to drought. The two most drought tolerant accessions were grouped together and the 5th and 6th most drought tolerant accession were also grouped together. This suggests that the genotypes grouped together may be genetically close, may possess similar genes or have a common origin. The degree of genetic variants obtained could be useful in bambara groundnut breeding for drought tolerance. The identified drought tolerant bambara groundnut landraces are important genetic resources for drought stress tolerance breeding programme of bambara groundnut. The genotypes are also useful for germplasm conservation and global implications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bambara%20groundnut" title="bambara groundnut">bambara groundnut</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20diversity" title=" genetic diversity"> genetic diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=germplasm" title=" germplasm"> germplasm</a>, <a href="https://publications.waset.org/abstracts/search?q=SSR%20markers" title=" SSR markers"> SSR markers</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20stress" title=" water stress"> water stress</a> </p> <a href="https://publications.waset.org/abstracts/192287/morpho-agronomic-response-to-water-stress-of-some-nigerian-bambara-groundnut-vigna-subterranea-l-verdc-germplasm-and-genetic-diversity-studies-of-some-selected-accessions-using-ssr-markers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192287.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">20</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Water Stress Response Profiling of Nigerian Bambara Groundnut (Vigna subterranea L.

However, fixation identification techniques are frequently discussed informally and rarely compared in any meaningful way. With two state-of-the-art algorithms, we will implement fixation detection and analysis in this work. The velocity threshold fixation algorithm is the first algorithm, and it identifies fixation based on a threshold value. For eye movement detection, the second approach is U'n' Eye, a deep neural network algorithm. The goal of this project is to analyze and visualize eye-tracking data from an eye gaze dataset that has been provided. The data was collected in a scenario in which individuals were shown photos and asked whether or not they recognized them. The results of the two-fixation detection approach are contrasted and visualized in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human-computer%20interaction" title="human-computer interaction">human-computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=eye-tracking" title=" eye-tracking"> eye-tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=CNN" title=" CNN"> CNN</a>, <a href="https://publications.waset.org/abstracts/search?q=fixations" title=" fixations"> fixations</a>, <a href="https://publications.waset.org/abstracts/search?q=saccades" title=" saccades"> saccades</a> </p> <a href="https://publications.waset.org/abstracts/149628/analyze-and-visualize-eye-tracking-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149628.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">135</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> The Role of Tourism Industry in the Creation of Youth Employment Opportunities in Africa: A Case Study of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isiya%20Salihu%20Shinkafi">Isiya Salihu Shinkafi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The focus of this paper is to elaborate on employment opportunities within the tourism sector and the solutions to youth unemployment in Africa and Nigeria in particular. Youth unemployment creates a monumental social problem to African continent, the world over and Nigeria in particular. The intelligence of this paper was collected from secondary sources using previews researches and analysis of scholars to gather empirical data. The findings revealed that unemployment in Africa and specifically Nigeria among youths were caused by certain factors which constitute a greater challenge to the economy and the existence of the continent. The tourism sector provides the enabling environment to address the different categories of unemployment among the youths. One of the unique characteristics of the tourism industry that makes it a prime sector from which employment can be engineered; especially in the case of the African countries, are its labour intensive characteristics of both experts, skilled, semi-skilled and unskilled labour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tourism%20industry" title="tourism industry">tourism industry</a>, <a href="https://publications.waset.org/abstracts/search?q=employment%20opportunities" title=" employment opportunities"> employment opportunities</a>, <a href="https://publications.waset.org/abstracts/search?q=youth%20employment" title=" youth employment"> youth employment</a> </p> <a href="https://publications.waset.org/abstracts/12524/the-role-of-tourism-industry-in-the-creation-of-youth-employment-opportunities-in-africa-a-case-study-of-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12524.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">25</span> SME Credit Financing, Financial Development and Economic Growth: A VAR Approach to the Nigerian Economy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bolaji%20Adesoye">A.

The study also explores IRFs and FEVDs in a system that includes output, commercial bank loan to SMEs, domestic credit to private sector by banks, money supply, lending rate and investment. Findings suggest that shocks in commercial bank credit to SMEs has a major impact on the output changes of Nigeria. Money supply shocks also have a sizeable impact on output growth variations amidst other financial instruments. Lastly, neutrality of investment does not hold in Nigeria as it also has impact on output fluctuations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SMEs%20financing" title="SMEs financing">SMEs financing</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20development" title=" financial development"> financial development</a>, <a href="https://publications.waset.org/abstracts/search?q=investment" title=" investment"> investment</a>, <a href="https://publications.waset.org/abstracts/search?q=output" title=" output"> output</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/35590/sme-credit-financing-financial-development-and-economic-growth-a-var-approach-to-the-nigerian-economy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35590.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">408</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> Textile Cottage Industry: A Facilitator for Capacity Building and Youth Empowerment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salihu%20Maiwada">Salihu Maiwada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The large scale textile industry in Nigeria was at one time the second largest employer of labor after government. With recent developments and changing situations, there is a serious decline in this sector which consequently forced the local textile industries to close down and the workers retrenched. the category of people worst hit was the youths and the middle age. This paper examines the potentials of the textile cottage industry as a facilitator for capacity building and economic empowerment among the Nigerian youths. The paper focuses on economic viability, persistence, and above-all, its potentials for poverty reduction as well as self employment. The methodology used in the study is the survey method and the instrument used to collect the necessary information is field interview. The results obtained showed that the textile cottage industries are flourishing and the Nigerian youths are engaged in the practice. In addition, the paper suggests areas that require government's financial intervention which will facilitate the establishment and ensure the sustainability of the textile cottage industry. The paper concludes with some recommendations for the youths and for the government. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capacity%20building" title="capacity building">capacity building</a>, <a href="https://publications.waset.org/abstracts/search?q=economic" title=" economic"> economic</a>, <a href="https://publications.waset.org/abstracts/search?q=empowerment" title=" empowerment"> empowerment</a>, <a href="https://publications.waset.org/abstracts/search?q=persistence" title=" persistence"> persistence</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=youths" title=" youths"> youths</a> </p> <a href="https://publications.waset.org/abstracts/27459/textile-cottage-industry-a-facilitator-for-capacity-building-and-youth-empowerment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27459.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">587</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> Enterpreneurship as a Strategic Tool for Higher Productivity in Nigerian Universities System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yahaya%20Salihu%20Emeje">Yahaya Salihu Emeje</a>, <a href="https://publications.waset.org/abstracts/search?q=Amuchie%20Austine%20Anthony"> Amuchie Austine Anthony</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The topic examined the prospects of entrepreneurship as an emerging dynamic and strategic tool in the upliftment of human and non-human resources in the Nigerian university system, with a view of showcasing the abundant positive impact, on the Nigerian University system in particular and Nigerian economy at large.

The length-weight relationship of O.niloticus showed a strong regression coefficient (r = 0.944) (p<0.05) for the combined sex, (r =0.901) (p<0.05) for female and (r=0.985) (p<.05) for male with b-value of 2.5, 3.1 and 2.8 respectively. The S.galilaeus also showed a regression coefficient of r=0.970; p<0.05 for the combined sex, r=0.953; p<0.05 for the female and r= 0.979; p<0.05 for the male with b-value of 3.4, 3.1 and 3.6 respectively. O.niloticus showed an isometric growth pattern both in male and female. The condition factor in O.niloticus are 1.93 and 1.95 for male and female respectively while that of S.galilaeus is 1.95 for both sexes. Positive allometric was observed in both species except the male O.niloticus that showed negative allometric growth pattern. From the results of this study, the growth pattern of the two species indicated a good healthy environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Epe%20Lagoon" title="Epe Lagoon">Epe Lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=length-weight%20relationship" title=" length-weight relationship"> length-weight relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis%20niloticus" title=" Oreochromis niloticus"> Oreochromis niloticus</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarotherodon%20galilaeus" title=" Sarotherodon galilaeus"> Sarotherodon galilaeus</a> </p> <a href="https://publications.waset.org/abstracts/94857/growth-pattern-and-condition-factor-of-oreochromis-niloticus-and-sarotherodon-galilaeus-in-epe-lagoon-lagos-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94857.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">21</span> Experimental Study of Mixture of R290/R600 to Replace R134a in a Domestic Refrigerator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20O.%20Babarinde">T.

Due to the depletion of ozone-layer and global warming effects, synthetic refrigerants are being gradually phased out in accordance with the international protocols that aim to protect the environment. In this work, a refrigerator designed to work with R134a was used for this experiment, Liquefied Petroleum Gas (LPG) which consists of commercial propane and butane in a single evaporator domestic refrigerator with a total volume of 62 litres. In this experiment, type K thermocouples with their probes were used to measure the temperatures of four major components (evaporator, compressor, condenser and expansion device) of the refrigeration system. Also the system was instrumented with two pressure gauges at the inlet and outlet of the compressor for measuring the suction and discharged pressures. The experiments were carried out using 40, 60, 80,100g charges and the charges were measured with a digital charging scale. Thermodynamic properties of the LPG refrigerant were determined. The results obtained showed that using LPG charge of 60g. The system COP increased with 14.6% and the power consumption reduced with 9.8% when compared with R134a. Therefore, LPG can replace R134a in domestic refrigerator. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=domestic%20refrigerator" title="domestic refrigerator">domestic refrigerator</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental" title=" experimental"> experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=LPG" title=" LPG"> LPG</a>, <a href="https://publications.waset.org/abstracts/search?q=R134a" title=" R134a "> R134a </a> </p> <a href="https://publications.waset.org/abstracts/24495/experimental-study-of-mixture-of-r290r600-to-replace-r134a-in-a-domestic-refrigerator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24495.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">482</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> The States of Stage Indigenous Operatic Production in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20Bolaji">David Bolaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Operatic production in Nigeria emanates from the traditional theatrical performances rooted in the ritual festival and traditional religious ceremonies among different cultures in Nigeria. The existence and the performative continuum of opera in Nigeria have been in the limelight of stage productions and diverse performances before the presence of Europeans in Nigeria. However, the transformation of this musical genre evolved from an indigenous concept into an art form that is acceptable within the circumference theatrical platform globally. The present state of stage operatic production has gone into extinction as the result of diverse factors, which include: a lack of scripted operatic works by Nigerian art composers, disconnection and lack of continuation from the artistic, theatrical contributions of the foremost folk operatic practitioners in Nigeria and lack of progressive transformation of stage operatic production into screen production in Nigeria. The bibliography method was employed in this study. Also, the use of interviews and questionnaires was adopted. Findings reveal that the extinction of operatic production can be corrected through the intentional act of composing scripted operatic works by Nigerian art composers; by establishing a collaborative effort between the scriptwriters (librettists) and the Nigerian art composers, operatic stage performance could be transformed in screen production to create more awareness of it in the society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=operatic%20production" title="operatic production">operatic production</a>, <a href="https://publications.waset.org/abstracts/search?q=extinction" title=" extinction"> extinction</a>, <a href="https://publications.waset.org/abstracts/search?q=nigerian%20art%20music" title=" nigerian art music"> nigerian art music</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20nigerian%20art%20composers" title=" and nigerian art composers"> and nigerian art composers</a> </p> <a href="https://publications.waset.org/abstracts/161635/the-states-of-stage-indigenous-operatic-production-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161635.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">98</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> Ubiquitous Collaborative Mobile Learning (UCML): A Flexible Instructional Design Model for Social Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hameed%20Olalekan%20Bolaji">Hameed Olalekan Bolaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The digital natives are driving the trends of literacy in the use of electronic devices for learning purposes.

The vegetable oil – based epoxy material are sustainable, renewable and biodegradable materials replacing petrochemical – based epoxy materials in some applications. Polystyrene is highly brittle with limited mechanical applications. Raw neem seed oil was obtained from National Research Institute for Chemical Technology (NARICT), Zaria, Nigeria. The oil was epoxidized at 60 0C for three (3) hours using formic acid generated in situ. The epoxidized oil was characterized using Fourier Transform Infrared spectroscopy (FTIR). The disappearance of C = C stretching peak around 3011.7 cm-1and formation of a new absorption peak around 943 cm-1 indicate the success of epoxidation. The epoxidized oil was blended with pure polystyrene in different weight percent compositions using solution casting in chloroform. The tensile properties of the blends demonstrated that the addition of 5 wt % ENO to PS led to an increase in elongation at break, but a decrease in tensile strength and modulus. This is in accordance with the common rule that plasticizers can decrease the tensile strength of the polymer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title="biodegradable">biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=elongation%20at%20break" title=" elongation at break"> elongation at break</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxidation" title=" epoxidation"> epoxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20fatty%20acids" title=" epoxy fatty acids"> epoxy fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength%20and%20modulus" title=" tensile strength and modulus"> tensile strength and modulus</a> </p> <a href="https://publications.waset.org/abstracts/70061/an-evaluation-of-the-impact-of-epoxidized-neem-seed-azadirachta-indica-oil-on-the-mechanical-properties-of-polystyrene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70061.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">234</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> Removal of Mixed Heavy Metals from Contaminated Clay Soils Using Pulsed Electrokinetic Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuhu%20Dalhat%20Mu%E2%80%99azu">Nuhu Dalhat Mu’azu</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullahi%20Usman"> Abdullahi Usman</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Bukhari"> A.

The effects of voltage gradient, pulse duty cycle and bentonite/clay ratio on the simultaneous removal efficiencies of the heavy metals were investigated. A total of thirteen experiments were designed and conducted according to factorial design with each experiment allowed to continuously ran for 3 weeks. Results obtained showed that increase in bentonite ratio decreased the removal efficiency of the heavy metals with no significant effect on the energy consumption. Conversely, increase in both voltage gradient and pulse duty cycle increased the heavy metals removal efficiencies with increased in energy consumption. Additionally, increase in voltage gradient increased the electrical conductivity and the soil pH due to due to continuous refill and replacement of process fluids as they decomposed under the induced voltage gradient. Under different operating conditions, the maximum removal efficiencies obtained for Cr, Cu, Hg, and Pb were 21.87, 83.2, 62.4, 78.06 and 16.65% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clay" title="clay">clay</a>, <a href="https://publications.waset.org/abstracts/search?q=bentonite" title=" bentonite"> bentonite</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20remediation" title=" soil remediation"> soil remediation</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20contaminants" title=" mixed contaminants"> mixed contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20electrokinetic-adsorption" title=" and electrokinetic-adsorption"> and electrokinetic-adsorption</a> </p> <a href="https://publications.waset.org/abstracts/30898/removal-of-mixed-heavy-metals-from-contaminated-clay-soils-using-pulsed-electrokinetic-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30898.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">16</span> Open Education Resources a Gateway for Accessing Hospitality and Tourism Learning Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Isiya%20Shinkafi%20Salihu">Isiya Shinkafi Salihu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open education resources (OER) are open learning materials in different formats, course content and context to support learning globally. This study investigated the level of awareness of Hospitality and Tourism OER among students in the Department of Tourism and Hotel Management in a University. Specifically, it investigated students’ awareness, use and accessibility of OER in learning. The research design method used was the quantitative approach, using an online questionnaire. The thesis research shows that respondents frequently use OER but with little knowledge of the content and context of the material. Most of the respondents’ have little knowledge about the concept even though they use it. Information and communication technologies are tools for information gathering, social networking and knowledge sharing and transfer. OER are open education materials accessible online such as curriculum, maps, course materials, and videos that users create, adapt, reuse for learning and research. Few of the respondents that used OER in learning faced some challenges such as high cost of data, poor connectivity and lack of proper guidance. The results suggest a lack of awareness of OER among students in the faculty of tourism and the need for support from the teachers in the utilization of OER. The thesis also reveals that some of the international students are accessing the internet as beginners in their studies which require guidance. The research, however, recommends that further studies should be conducted to other faculties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creative%20commons" title="creative commons">creative commons</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20education%20resources" title=" open education resources"> open education resources</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20licenses" title=" open licenses"> open licenses</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communication%20technology" title=" information and communication technology"> information and communication technology</a> </p> <a href="https://publications.waset.org/abstracts/135241/open-education-resources-a-gateway-for-accessing-hospitality-and-tourism-learning-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135241.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">177</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> Review of Assessment of Integrated Information System (IIS) in Organisation </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariya%20Salihu%20Ingawa">Mariya Salihu Ingawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sani%20Suleiman%20Isah"> Sani Suleiman Isah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The assessment of Integrated Information System (IIS) in organisation is an important initiative to enable the Information System (IS) managers, as well as top management to understand the success status of their investment in IS integration efforts. However, without a proper assessment, an organisation will not know its IIS status, which may affect their judgment on what action should be taken onwards. Current research on IIS assessment is lacking and those related literature on IIS assessment focus more on assessing the technical aspect of IIS. It is argued that assessing technical aspect alone is inadequate since organisational and strategic aspects in IIS should also be considered. Current methods, techniques and tools used by vendors for IIS assessment also are lack of comprehensive measures to fully assess the Integrated Information System in term of technical, organisational and strategic domains. The purpose of this study is to establish critical success factors for measuring success of an Integrated Information System. These factors are used as the basis for constructing an approach to comprehensively assess IIS in an organisation. A comprehensive list of success factors for IIS assessment, established from literature, was initially presented. An expert surveys using both manual and online methods were conducted to verify the factors. Based on the factors, an instrument for IIS assessment was constructed. The results from a case study indicate that through comprehensive assessment approach, not only the level of success been known, but also reveals the contributing factors. This research contributes to the field of Information Systems specifically in the area of Integrated Information System assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20information%20system" title="integrated information system">integrated information system</a>, <a href="https://publications.waset.org/abstracts/search?q=expert%20surveys" title=" expert surveys"> expert surveys</a>, <a href="https://publications.waset.org/abstracts/search?q=organisation" title=" organisation"> organisation</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a> </p> <a href="https://publications.waset.org/abstracts/22657/review-of-assessment-of-integrated-information-system-iis-in-organisation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22657.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">388</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> Evidence Based Policy Studies: Examining Alternative Policy Practice towards Improving Enrolment to Higher Education in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muftahu%20Jibirin%20Salihu">Muftahu Jibirin Salihu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazri%20Jamil"> Hazri Jamil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The persisting challenge of access and enrolment to higher education in commonwealth countries has been reported in several studies, including reports of the international organization such as World Bank, UNESCO among others however from the macro perspective. The overarching aim of this study is to examine alternative policy practices towards improving access to university education in Nigeria at meso level of policy practice from evidence base policy studies using one university as a case. The study adopted a qualitative approach to gain insightful understanding on the issue of the study employing a semi-structure interview and policy documents as the means for obtaining the data and other relevant information for the study. The participants of the study were purposively chosen which comprise of a number of individuals from the selected university and other related organization which responsible for the policies development and implementation of Nigerian higher education system. From the findings of the study, several initiatives have been taken at meso level to address this challenge including the introduction of the University Matriculation Program as an alternative route for enhancing to access to the university education. However, the study further provided a number of recommendations which aimed at improving access to university education such as improving the entry requirements, society orientation on university education and the issue of ranking of certificate among the Nigerian higher institutions of learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=policy%20practice" title="policy practice">policy practice</a>, <a href="https://publications.waset.org/abstracts/search?q=access" title=" access"> access</a>, <a href="https://publications.waset.org/abstracts/search?q=enrolment" title=" enrolment"> enrolment</a>, <a href="https://publications.waset.org/abstracts/search?q=university" title=" university"> university</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/52638/evidence-based-policy-studies-examining-alternative-policy-practice-towards-improving-enrolment-to-higher-education-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52638.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">267</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> An Ideational Grammatical Metaphor of Narrative History in Chinua Achebe's 'There Was a Country'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammed-Badar%20Salihu%20Jibrin">Muhammed-Badar Salihu Jibrin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chibabi%20Makedono%20Darlington"> Chibabi Makedono Darlington</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper studied Ideational Grammatical Metaphor (IGM) of Narrative History in Chinua Achebe’s There Was a Country. It started with a narrative historical style as a recent genre out of the conventional historical writings. In order to explore the linguistic phenomenon using a particular lexico-grammatical tool of IGM, the theoretical background was examined based on Hallidayan Systemic Functional Linguistics. Furthermore, the study considered the possibility of applying IGM to the Part 4 of Achebe’s historical text with recourse to the concept of congruence in IGM and research questions before formulating a working methodology. The analysis of Achebe’s memoir was, thus, presented in tabular forms to account for the quantitative content analysis with qualitative research technique, as well as the metaphorical and congruent wording through nominalization and process types with samples. The frequencies and percentage were given appropriately with respect to each subheadings of the text. To this end, the findings showed that material and relational types indicated dominance. The discussion and implications were that the findings confirmed earlier study by MAK Halliday and C.I.M.I.M. Matthiessen’s suggestion that IGM should show dominance of material type process. The implication is that IGM can be an effective tool for the analysis of a narrative historical text. In conclusion, it was observed that IGM does not only carry grammatical function but also an ideological role in shaping the historical discourse within the narrative mode between writers and readers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ideational%20grammatical%20metaphor" title="ideational grammatical metaphor">ideational grammatical metaphor</a>, <a href="https://publications.waset.org/abstracts/search?q=nominalization" title=" nominalization"> nominalization</a>, <a href="https://publications.waset.org/abstracts/search?q=narrative%20history" title=" narrative history"> narrative history</a>, <a href="https://publications.waset.org/abstracts/search?q=memoire" title=" memoire"> memoire</a>, <a href="https://publications.waset.org/abstracts/search?q=dominance" title=" dominance"> dominance</a> </p> <a href="https://publications.waset.org/abstracts/99816/an-ideational-grammatical-metaphor-of-narrative-history-in-chinua-achebes-there-was-a-country" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99816.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">220</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> Effectiveness of Coping Strategies Adopted by the Small Holder Farmers for Poverty Alleviation 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=Noimot%20A.%20Bakare">Noimot A.

Data were collected with the aid of interview schedule. A multistage random sampling technique was used to select 225 respondents from 3 geographical zones in the State. Data were analyzed using descriptive and inferential statistics. The results showed that majority (83.1%) of the respondents were within the age of 21-50 years, mostly male (76.0%) and married (77.8%). The highest educational level attained was quranic education. Findings showed that coping strategies commonly adopted by the farmers were; use of food stuff (94.2%), money savings(76.6%), reduction in expenditure(74.2%) and food consumption (65.2%). Also, there was high awareness of primary healthcare and fadama development poverty alleviation programmes by Government and non-governmental organizations. Regression model indicated a significant and positive relationship between the educational level of farmers, farm size, contact with extension and effectiveness of poverty coping strategies. Pearson correlation coefficient shows a correlation between coping strategies adopted and their effectiveness(r = 0.599, P < 0.01). However, t- test shows a significant difference between coping strategies adopted by the male and female farmers (t= -2.63, P < 0.01). It is recommended that awareness on poverty alleviation programmes aimed at improving the productivity of farming activities should be intensified while farmers should be involved in the planning and implementation of these programmes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coping%20strategies" title="coping strategies">coping strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=effectiveness" title=" effectiveness"> effectiveness</a>, <a href="https://publications.waset.org/abstracts/search?q=farmers" title=" farmers"> farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=poverty%20alleviation." title=" poverty alleviation."> poverty alleviation.</a> </p> <a href="https://publications.waset.org/abstracts/28049/effectiveness-of-coping-strategies-adopted-by-the-small-holder-farmers-for-poverty-alleviation-in-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28049.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">363</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> Effect of Formative Evaluation with Feedback on Students Economics Achievement in Secondary Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salihu%20Abdullahi%20Galle">Salihu Abdullahi Galle</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Students' performance in Economics in schools and on standardized exams in Nigeria has been worrying throughout the years, owing to some teachers' use of conventional and lecture teaching methods. Other obstacles include a lack of training, standardized testing pressure, and aversion to change, all of which can have an impact on students' cognitive ability in Economics and future careers. The researchers employed formative evaluation with feedback (FEFB) to support the teaching and learning process by providing constant feedback to both teachers and students. The researchers employed a quasi-experimental research design to examine two teaching methods (FEFB and traditional). The pre-test and post-test interaction effects were evaluated between students in the experimental group (FEFB) and those in the conventional group. The interaction effects of pre-test and post-test on male and female in the two groups were also examined, with 90 participants. The findings show that students exposed to a FEFB-based teaching approach outperform pupils taught in a traditional classroom setting, and there is no gender interaction effect between the two groups. In light of these findings, the researchers urge that Economics teachers employ FEFB during teaching and learning to ensure timely feedback, and that policymakers ensure that Economics teachers receive training and re-training on FEFB approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=formative%20evaluation%20with%20feedback%20%28FEFB%29" title="formative evaluation with feedback (FEFB)">formative evaluation with feedback (FEFB)</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a>, <a href="https://publications.waset.org/abstracts/search?q=economics%20achievement" title=" economics achievement"> economics achievement</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20education" title=" secondary education"> secondary education</a> </p> <a href="https://publications.waset.org/abstracts/185763/effect-of-formative-evaluation-with-feedback-on-students-economics-achievement-in-secondary-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185763.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">49</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> Validation of SWAT Model for Prediction of Water Yield and Water Balance: Case Study of Upstream Catchment of Jebba Dam in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adeniyi%20G.%20Adeogun">Adeniyi G.

Therefore, in the present study, Soil and Water Assessment Tool (SWAT) interfaced with Geographical Information System (GIS) was applied as a tool to predict water balance and water yield of a catchment area in Nigeria. The catchment area, which was 12,992km2, is located upstream Jebba hydropower dam in North central part of Nigeria. In this study, data on the observed flow were collected and compared with simulated flow using SWAT. The correlation between the two data sets was evaluated using statistical measures, such as, Nasch-Sucliffe Efficiency (NSE) and coefficient of determination (R2). The model output shows a good agreement between the observed flow and simulated flow as indicated by NSE and R2, which were greater than 0.7 for both calibration and validation period. A total of 42,733 mm of water was predicted by the calibrated model as the water yield potential of the basin for a simulation period 1985 to 2010. This interesting performance obtained with SWAT model suggests that SWAT model could be a promising tool to predict water balance and water yield in sustainable management of water resources. In addition, SWAT could be applied to other water resources in other basins in Nigeria as a decision support tool for sustainable water management in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GIS" title="GIS">GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=sensitivity%20analysis" title=" sensitivity analysis"> sensitivity analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT" title=" SWAT"> SWAT</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20yield" title=" water yield"> water yield</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed%20level" title=" watershed level"> watershed level</a> </p> <a href="https://publications.waset.org/abstracts/3782/validation-of-swat-model-for-prediction-of-water-yield-and-water-balance-case-study-of-upstream-catchment-of-jebba-dam-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3782.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">439</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> Effect of Depth on the Distribution of Zooplankton in Wushishi Lake Minna, Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adamu%20Zubairu%20Mohammed">Adamu Zubairu Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Fransis%20Oforum%20Arimoro"> Fransis Oforum Arimoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Salihu%20Maikudi%20Ibrahim"> Salihu Maikudi Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Y.%20I.%20Auta"> Y.

Water and zooplankton samples were collected from the surface, 3.0 meters deep and 6.0 meters deep, for a period of 24 hours for six months. Standard procedures were adopted for the determination of physicochemical parameters. Results have shown significant differences in the pH, DO, BOD Hardness, Na, and Mg. A total of 1764 zooplankton were recorded, comprising 35 species, with cladocera having 18 species (58%), 14 species of copepoda (41%), 3 species of diptera (1.0%). Results show that more of the zooplankton were recorded in the 3.0 meters-deep region compared to the two other depts and a significant difference was observed in the distribution of Ceriodaphnia dubia, Daphnia laevis, and Leptodiaptomus coloradensis. Though the most abundant zooplankton was recorded in the 3.0 meters deep, Leptodiaptomus coloradesnsis, which was observed in the 6.0 meters deep as the most individual observed, this was followed by Daphnia laevis. Canonical correspondence analysis between physicochemical parameters and the zooplankton indicated a good relationship in the Lake. Ceriodaphnia dubia was found to have a good association with oxygen, sodium, and potassium, while Daphnia laevis and Leptodiaptomus coloradensis are in good relationship with magnesium and phosphorus. It was generally observed that this depth does not have much influence on the distribution of zooplankton in Wushishi Lake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zooplankton" title="zooplankton">zooplankton</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20procedures" title=" standard procedures"> standard procedures</a>, <a href="https://publications.waset.org/abstracts/search?q=canonical%20correspondence%20analysis" title=" canonical correspondence analysis"> canonical correspondence analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Wushishi" title=" Wushishi"> Wushishi</a>, <a href="https://publications.waset.org/abstracts/search?q=canonical" title=" canonical"> canonical</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20parameter" title=" physicochemical parameter"> physicochemical parameter</a> </p> <a href="https://publications.waset.org/abstracts/172173/effect-of-depth-on-the-distribution-of-zooplankton-in-wushishi-lake-minna-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172173.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">90</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">8</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.

This study, therefore, determined the impacts of CAI onhigh-flyers pre-service teachers’ attitude towards AE concepts in Southwest, Nigeria. The study adopted pretest-posttest, control group, quasi-experimental design. Six CoE with e-library facilities were purposively selected. Fourty-nine 200 level Agricultural education students offering introduction to AE course across the six CoE were participants. The participants were assigned to two groups (CAI, 22 and control, 27). Treatment lasted eight weeks. The AE Attitude Scale(r=0.80), Instructional guides and Teacher Performance Assessment Sheets were used for data collection. Data were analysed using t-test. The participants were 62.8% male with mean age of 22 years. Treatment had significant effects on high-flyers pre-service teachers’ attitude (t = 17.44; df = 47, p < .5). Participants in CAI ( =71.03) had higher post attitude mean score compared to those in control ( = 64.92) groups. Gender had no significant effect on attitude (t= 3.06; df= 47, p > .5). The computer assisted instructional mode enhanced students’ attitude towards Agricultural Economics concepts. Therefore, CAI should be adopted for improved attitude towards agricultural economics concepts among high-flyers pre-service teachers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitude%20towards%20agricultural%20economics%20concepts" title="attitude towards agricultural economics concepts">attitude towards agricultural economics concepts</a>, <a href="https://publications.waset.org/abstracts/search?q=colleges%20of%20education%20in%20southwest%20Nigeria" title=" colleges of education in southwest Nigeria"> colleges of education in southwest 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=high-flyers%20pre-service%20teachers" title=" high-flyers pre-service teachers "> high-flyers pre-service teachers </a> </p> <a href="https://publications.waset.org/abstracts/72270/impacts-of-computer-assisted-instruction-and-gender-on-high-flyers-pre-service-teachers-attitude-towards-agricultural-economics-in-southwest-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72270.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">249</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">7</span> Perceived Physical Exercise Benefits among Staff of Tertiary Institutions in Adamawa State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salihu%20Mohammed%20Umar">Salihu Mohammed Umar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Perceived physical exercise benefits among staff of tertiary institutions in Adamawa State was investigated as a basis for formulating proper exercise intervention strategies. The study utilized descriptive survey design. The purpose of the study was to determine perceived exercise benefits among staff of tertiary institutions in Adamawa state, Nigeria. The instrument used for data collection was a questionnaire adapted from Exercise Benefit/Barrier Scale (EBBS) developed by Sechrist, Walker and Pender (1985) which was validated by five experts. Three hundred and thirty (330) copies of the questionnaire were distributed among study participants in six institutions of higher learning in Adamawa state. The scale comprised two components; Benefits and Barriers dimensions. To achieve this purpose, three research questions were posed. The instrument had a four response forced-choice Likert-type format with responses ranging from 4 = strongly agree (SA), 3 = Agree (A), 2 = Disagree (D) and 1 = Strongly Disagree (SD). The findings of the study revealed that both male and female staff in institutions of higher learning in Adamawa state perceived exercise as highly beneficial. However, male staff had higher perceived benefits score than their female counterparts. (Male: x̄ = 95.02. SD = 3.08) > female: x̄ = 94.04, SD = 4.35. There was also no significant difference in perceived exercise barriers between staff and students of tertiary institutions in Adamawa state. Based on the finding of the study, it was concluded that staff of tertiary institutions perceived exercise as highly beneficial. It was recommended that since staff of institutions of higher learning in Adamawa State irrespective of gender and religious affiliations have basic knowledge of perceived benefits of exercise, there is the need to explore programmes that will enable staff across the sub-groups to overcome barriers that could discourage physical exercise participation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perception" title="perception">perception</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20exercise" title=" physical exercise"> physical exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=staff" title=" staff"> staff</a>, <a href="https://publications.waset.org/abstracts/search?q=benefits" title=" benefits"> benefits</a> </p> <a href="https://publications.waset.org/abstracts/67113/perceived-physical-exercise-benefits-among-staff-of-tertiary-institutions-in-adamawa-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67113.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">316</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">6</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 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.

This would minimize the dependence on fossil fuels and serve as future alternatives. Organic wastes contain carbohydrates, proteins and lipids, which can be utilised as carbon sources for the production of bio-based products. Cellulose is the most abundant natural biopolymer, being the main structural component of lignocellulosic materials. The aim of this project is to develop a biological process for the hydrolysis and fermentation of organic wastes into ethanol and organic acids. The hydrolysis and fermentation processes are integrated in a single vessel using undefined mixed culture microorganisms. The anaerobic fermentation of microcrystalline cellulose was investigated in continuous and batch reactors at 25°C with an appropriate growth medium for cellulase formation, hydrolysis, and fermentation. The reactors were inoculated with soil (B1, C1, C3) or sludge from an anaerobic digester (B2, C2) and the breakdown of cellulose was monitored by measuring the production of ethanol, organic acids and the residual cellulose. The batch reactors B1 and B2 showed negligible microbial activity due to inhibition while the continuous reactors, C1, C2 and C3, exhibited little cellulose hydrolysis which was concealed by the cellulose accumulation in the reactor. At the end of the continuous operation, the reactors C1, C2 and C3 were operated under batch conditions. 48%, 34% and 42% cellulose had been fermented by day 88, 55 and 55 respectively of the batch fermentation. Acetic acid, ethanol, propionic acid and butyric acids were the main fermentation products in the reactors. A stable concentration of 0.6 g/l ethanol and 5 g/L acetic acid was maintained in C3 for several weeks due to reduced activity of methanogens caused by the decrease in pH. Thus far, the results have demonstrated that mixed microbial culture is capable of hydrolysing and fermenting cellulose under lenient conditions. The fermentation of cellulose has been found effective in a combination of continuous and batch processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose" title="cellulose">cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrolysis" title=" hydrolysis"> hydrolysis</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20culture" title=" mixed culture"> mixed culture</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20waste" title=" organic waste"> organic waste</a> </p> <a href="https://publications.waset.org/abstracts/40539/process-development-for-the-conversion-of-organic-waste-into-valuable-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40539.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">367</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">4</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">3</span> Mechanical and Physical Properties of Wood Composite Panel from Recycled Plastic and Sawdust of Cordia alliodora (Ruiz and Pav.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Bolaji%20Alarape">Ahmed Bolaji Alarape</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwatobi%20Damilola%20Aba"> Oluwatobi Damilola Aba</a>, <a href="https://publications.waset.org/abstracts/search?q=Usman%20Shehu"> Usman Shehu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood plastic composite boards were made from sawn dust of Cordia alliodora and recycled polyethylene at a mixing ratio of 1.5ratio1, 2.5ratio1 and 3.5ratio1 and nominal densities of 600 kilograms per meter cube, 700 kilograms per meter cube, and 800 kilograms per meter cube, The material was hot pressed at 150-degree celsius to produce board of 250 millimeter by 250 millimeter by 6 millimeter of which 18 boards were produced. The experiment was subject to 3 by 3 factorial experiments in Completely Randomised Design (CRD). Analysis of variance and Duncan Multiple Range Test (DMRT) was adopted by 3 by 3 at 5 percent probability. The strength properties of the boards such as modulus of rupture (MOR) and modulus of elasticity (MOE) were investigated, while the dimensional properties of the board such as the water absorption (WA) and thickness swelling (TS) were as well determined after 12hrs and 24hrs of water immersion. The result showed that the mean values of MOE ranged from 9100.73 Newtons per square millimeters to 12086.96 Newtons per square millimeters while MOR values ranged from 48.26 Newtons per square millimeters to 103.09 Newtons per square millimeters. The values of WA and TS after 12hrs immersion ranged from 1.21 percent to 1.56 percent and 0.00 percent to 0.13 percent, respectively. The values of WA and TS after 24hrs of water immersion ranged from 1.66 percent to 2.99 percent and 0.02 percent to 0.18 percent, respectively. The higher the value of board density and the high-density polythene /sawdust ratio, the stronger, the stiffer and more dimensionally stable the wood plastic composite boards obtained. In addition, as the density of the board increases, the strength property of the boards increases. Hence the board will be suitable for internal construction materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20Plastic%20composite" title="wood Plastic composite">wood Plastic composite</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20rupture" title=" modulus of rupture"> modulus of rupture</a>, <a href="https://publications.waset.org/abstracts/search?q=modulus%20of%20elasticity" title=" modulus of elasticity"> modulus of elasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=dimensional%20stability" title=" dimensional stability"> dimensional stability</a> </p> <a href="https://publications.waset.org/abstracts/83704/mechanical-and-physical-properties-of-wood-composite-panel-from-recycled-plastic-and-sawdust-of-cordia-alliodora-ruiz-and-pav" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83704.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">178</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">2</span> Nutritional Characteristics, Phytochemical and Antimicrobial Properties Vaccinium Pavifolium (Ericacea) Leaf Protein Concentrates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sodamade%20A.">Sodamade A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bolaji%20K.%20A."> Bolaji K.

Huckleberry is one of the plants that has been proven useful locally in the treatment of numerous ailments and diseases. A fresh sample of the plant (Vaccinium pavifolium) was collected from a vegetable garden situated near the Erelu dam of the Emmanuel Alayande College of Education Campus, Oyo. The sample was authenticated at the Forestry Research Institute of Nigeria (FRIN) Ibadan. The leaves of the plant were plucked and processed for leaf protein concentrates before proximate composition, mineral analysis phytochemical and antimicrobial properties were determined using a standard method of analysis. The results of proximate constituents showed; moisture content; 9.89±0.051g/100g, Ash; 3.23±0.12g/100g, crude fat; 3.96±0.11g/100g and 61.27±0.56g/100g of Nitrogen free extractive. The mineral analysis of the sample showed; Mg; 0.081±0.00mg/100g, Ca; 42.30±0.05mg/100g, Na; 27.57±0.09mg/100g, K; 6.81±0.01mg/100g, P; 8.90±0.03mg/100g, Fe; 0.51±0.00mg/100g, Zn; 0.021±0.00mg/100g, Cd; 0.04±0.04mg/100g, Pb; 0.002±0.00mg/100g, Cr; 0.041±0.00mg/100g Cadmium and Mercury were not detected in the sample. The result of phytochemical analysis of leaf protein concentrates of the Huckleberry showed the presence of Alkaloid, Saponin, Flavonoid, Tanin, Coumarin, Steroids, Terpenoids, Cardiac glycosides, Glycosides, Quinones, Anthocyanin, phytosterols, and phenols. Ethanolic extracts of the Vaccinium parvifolium L. leaf protein concentrates showed that it contains bioactive compounds that are capable of combating the following microorganisms; Staphylococcus aureus, Streptococcus pyogenes, Streptococcus faecalis, Pseudomonas aeruginosa, Klebisialae pneumonia and Proteus mirabilis. The results of the analysis of Vaccinium parvifolium L. leaf protein concentrates showed that the sample contains valuable nutrient and mineral constituents, and phytochemical compounds that could make the sample useful for medicinal activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leaf%20protein%20concentrates" title="leaf protein concentrates">leaf protein concentrates</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccinium%20parvifolium" title=" vaccinium parvifolium"> vaccinium parvifolium</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20characteristics" title=" nutritional characteristics"> nutritional characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20composition" title=" mineral composition"> mineral composition</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a> </p> <a href="https://publications.waset.org/abstracts/171102/nutritional-characteristics-phytochemical-and-antimicrobial-properties-vaccinium-pavifolium-ericacea-leaf-protein-concentrates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171102.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">1</span> Moderating Effects of Family Ownership on the Relationship between Corporate Governance Mechanisms and Financial Performance of Publicly Listed Companies in Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ndagi%20Salihu">Ndagi Salihu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corporate governance mechanisms are the control measures for ensuring that all the interests groups are equally represented and management are working towards wealth creation in the interest of all. Therefore, there are many empirical studies during the last three decades on corporate governance and firm performance. However, little is known about the effects of family ownership on the relationship between corporate governance and firm performance, especially in the developing economy like Nigeria. This limit our understanding of the unique governance dynamics of family ownership with regards firm performance. This study examined the impact of family ownership on the relationship between governance mechanisms and financial performance of publicly listed companies in Nigeria. The study adopted quantitative research methodology using correlational ex-post factor design and secondary data from annual reports and accounts of a sample of 23 listed companies for a period of 5 years (2014-2018). The explanatory variables are the board size, board composition, board financial expertise, and board audit committee attributes. Financial performance is proxy by Return on Assets (ROA) and Return on Equity (ROE). Multiple panel regression technique of data analysis was employed in the analysis, and the study found that family ownership has a significant positive effect on the relationships between corporate governance mechanisms and financial performance of publicly listed firms in Nigeria. This finding is the same for both the ROA and ROE. However, the findings indicate that board size, board financial expertise, and board audit committee attributes have a significant positive impact on the ROA and ROE of the sample firms after the moderation. Moreover, board composition has significant positive effect on financial performance of the sample listed firms in terms of ROA and ROE. The study concludes that the use of family ownership in the control of firms in Nigeria could improve performance by reducing the opportunistic actions managers as well as agency problems. The study recommends that publicly listed companies in Nigeria should allow significant family ownership of equities and participation in management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=profitability" title="profitability">profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=board%20characteristics" title=" board characteristics"> board characteristics</a>, <a href="https://publications.waset.org/abstracts/search?q=agency%20theory" title=" agency theory"> agency theory</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders"> stakeholders</a> </p> <a href="https://publications.waset.org/abstracts/114637/moderating-effects-of-family-ownership-on-the-relationship-between-corporate-governance-mechanisms-and-financial-performance-of-publicly-listed-companies-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114637.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">140</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
