In these study, expanded polystyrene (EPS) was electrospun to produce beaded fibers in which zeolite was introduced to the polymer matrix in order to impart rough surface to non-beaded fiber. Films of the EPS and EPS/Zeolite solutions were also made for comparative study. The electrospun fibers EPS, EPS/Zeolite and resultant films were characterized using SEM, BET, FTIR and optical contact angle. The fibers exhibited superhydrophic and superoleophillic wetting properties with water and crude oil. The selective removal of crude oil presents new opportunity for the re-use of EPS as adsorbent in petroleum/petrochemical industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expanded%20polystyrene" title="expanded polystyrene">expanded polystyrene</a>, <a href="https://publications.waset.org/abstracts/search?q=superhydrophobic" title=" superhydrophobic"> superhydrophobic</a>, <a href="https://publications.waset.org/abstracts/search?q=superoleophillic" title=" superoleophillic"> superoleophillic</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-membrane" title=" oil-membrane"> oil-membrane</a> </p> <a href="https://publications.waset.org/abstracts/13690/surface-modified-electrospun-expanded-polystyrene-fibre-with-superhydrophobicsuperoleophillic-properties-as-potential-oil-membrane" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13690.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">472</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> The Digital Living Archive and the Construction of a Participatory Cultural Memory in the DARE-UIA Project: Digital Environment for Collaborative Alliances to Regenerate Urban Ecosystems in Middle-Sized Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Cardoni">Giulia Cardoni</a>, <a href="https://publications.waset.org/abstracts/search?q=Francesca%20Fabbrii"> Francesca Fabbrii</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Living archives perform a function of social memory sharing, which contributes to building social bonds, communities, and identities. This potential lies in the ability to live archives to put together an archival function, which allows the conservation and transmission of memory with an artistic, performative and creative function linked to the present. As part of the DARE-UIA (Digital environment for collaborative alliances to regenerate urban ecosystems in middle-sized cities) project the creation of a living digital archive made it possible to create a narrative that would consolidate the cultural memory of the Darsena district of the city of Ravenna. The aim of the project is to stimulate the urban regeneration of a suburban area of a city, enhancing its cultural memory and identity heritage through digital heritage tools. The methodology used involves various digital storytelling actions necessary for the overall narrative using georeferencing systems (GIS), storymaps and 3D reconstructions for a transversal narration of historical content such as personal and institutional historical photos and to enhance the industrial archeology heritage of the neighborhood. The aim is the creation of an interactive and replicable narrative in similar contexts to the Darsena district in Ravenna. The living archive, in which all the digital contents are inserted, finds its manifestation towards the outside in the form of a museum spread throughout the neighborhood, making the contents usable on smartphones via QR codes and totems inserted on-site, creating thematic itineraries spread around the neighborhood. The construction of an interactive and engaging digital narrative has made it possible to enhance the material and immaterial heritage of the neighborhood by recreating the community that has historically always distinguished it. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20living%20archive" title="digital living archive">digital living archive</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20storytelling" title=" digital storytelling"> digital storytelling</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=3D" title=" 3D"> 3D</a>, <a href="https://publications.waset.org/abstracts/search?q=open-air%20museum" title=" open-air museum"> open-air museum</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20regeneration" title=" urban regeneration"> urban regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=cultural%20memory" title=" cultural memory"> cultural memory</a> </p> <a href="https://publications.waset.org/abstracts/149533/the-digital-living-archive-and-the-construction-of-a-participatory-cultural-memory-in-the-dare-uia-project-digital-environment-for-collaborative-alliances-to-regenerate-urban-ecosystems-in-middle-sized-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149533.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">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Characteristics of the entrepreneurial professor: Educational Leadership and Higher Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Verde">Ana Verde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Higher education is now a source of new paradigms, advanced research in various fields of knowledge and an essential element in providing solutions to the major problems it faces today. In the education sector, more and more attention is being paid to the importance of entrepreneurship and the need for students to acquire skills in the classroom in order to be successful in their future careers. In the field of education, the term "teacherpreneur" has been coined in recent years to describe a teacher who is committed to educational change, passionate about his or her work, charismatic, self-confident, flexible, responsible, able to dare to break the established rules and take risks, and whose work is student-centred and action oriented. This research analyses the characteristics of the entrepreneurial professor and educational leader, and how their practice can be directed towards educational improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title="higher education">higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial" title=" entrepreneurial"> entrepreneurial</a>, <a href="https://publications.waset.org/abstracts/search?q=skills" title=" skills"> skills</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership" title=" leadership"> leadership</a> </p> <a href="https://publications.waset.org/abstracts/184205/characteristics-of-the-entrepreneurial-professor-educational-leadership-and-higher-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/184205.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">61</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Submicron Size of Alumina/Titania Tubes for CO2-CH4 Conversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chien-Wan%20Hun">Chien-Wan Hun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shao-Fu%20Chang"> Shao-Fu Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jheng-En%20Yang"> Jheng-En Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Chon%20Chen"> Chien-Chon Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Wern-Dare%20Jheng"> Wern-Dare Jheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research provides a systematic way to study and better understand double nano-tubular structure of alunina (Al2O3) and titania (TiO2). The TiO2 NT was prepared by immersing Al2O3 template in 0.02 M titanium fluoride (TiF4) solution (pH=3) at 25 °C for 120 min, followed by annealing at 450 °C for 1 h to obtain anatase TiO2 NT in the Al2O3 template. Large-scale development of film for nanotube-based CO2 capture and conversion can potentially result in more efficient energy harvesting. In addition, the production process will be relatively environmentally friendly. The knowledge generated by this research will significantly advance research in the area of Al2O3, TiO2, CaO, and Ca2O3 nano-structure film fabrication and applications for CO2 capture and conversion. This green energy source will potentially reduce reliance on carbon-based energy resources and increase interest in science and engineering careers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alumina" title="alumina">alumina</a>, <a href="https://publications.waset.org/abstracts/search?q=titania" title=" titania"> titania</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-tubular" title=" nano-tubular"> nano-tubular</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2" title=" CO2"> CO2</a> </p> <a href="https://publications.waset.org/abstracts/43703/submicron-size-of-aluminatitania-tubes-for-co2-ch4-conversion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43703.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">394</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> Rural Households' Sources of Water and Willingness to Pay for Improved Water Services 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=Alaba%20M.%20Dare">Alaba M.

This study examined rural households' sources of water, Willingness to Pay (WTP) and factors influencing mean WTP. A cross-sectional survey which involved the use of questionnaire was used. A dichotomous choice (DC) with follow up was used as elicitation method. A multi-stage random sampling technique was used to select 437 rural households. Descriptive statistics and Tobit model were used for data estimation. The result revealed that about 70% fetched from unimproved water sources. Most (74.4%) respondents showed WTP for improved water sources. Age (p < 0.01), sex (p < 0.01), education (p < 0.01), occupation (p < 0.01), income (p < 0.01), price of water (P < 0.01), quantity of water (p < 0.01), household size (p < 0.01) and distance (p < 0.01) to existing water sources significantly influenced rural households' WTP for these services. The inference from this study showed that rural dweller sources of water is highly primitive and deplorable. Governments and stakeholders should prioritize the provision of rural water at an affordable price by rural dwellers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=households" title="households">households</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20of%20water" title=" source of water"> source of water</a>, <a href="https://publications.waset.org/abstracts/search?q=willingness%20to%20pay%20%28WTP%29" title=" willingness to pay (WTP)"> willingness to pay (WTP)</a>, <a href="https://publications.waset.org/abstracts/search?q=tobit%20model" title=" tobit model"> tobit model</a> </p> <a href="https://publications.waset.org/abstracts/35488/rural-households-sources-of-water-and-willingness-to-pay-for-improved-water-services-in-south-west-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35488.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">382</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> The Potential for Recycling Household Wastes Generated from the Residential Areas of Obafemi Awolowo University, Ile-Ife</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asaolu%20Olugbenga%20Stephen">Asaolu Olugbenga Stephen</a>, <a href="https://publications.waset.org/abstracts/search?q=Afolabi%20Olusegun%20Temitope"> Afolabi Olusegun Temitope</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Lack of proper solid waste management is one of the main causes of environmental pollution and degradation in many cities, especially in developing countries. The aim of this study was to estimate the quantity of waste generated per capita per day, determine the composition and identify the potentials for recycling of waste generated. Characterization of wastes from selected households in the residential areas was done for over a 7 day period. The weight of each sorted category of waste was recorded in a structured database that calculated the proportion of each waste component. The results indicated that 85.4% of the sampled waste characterized was found to be recyclable; with an estimated average waste generated of 1.82kg/capita/day. The various solid waste fractions were organic (64.6%), plastics (15.6%), metals (9.2%), glass materials (1.6%) and unclassified (8.9%). It was concluded from this study that a large proportion of the waste generated from OAU campus residential area was recyclable and that there is a need to enact policy on waste recycling within the university campus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycling" title="recycling">recycling</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20wastes" title=" household wastes"> household wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=residential" title=" residential"> residential</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste%20management" title=" solid waste management"> solid waste management</a> </p> <a href="https://publications.waset.org/abstracts/35534/the-potential-for-recycling-household-wastes-generated-from-the-residential-areas-of-obafemi-awolowo-university-ile-ife" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35534.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">401</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> Barriers to Sports Participation as a Means of Achieving Sustainable Development in Michael Otedola College of Primary Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osifeko%20Olalekan%20Remigious">Osifeko Olalekan Remigious</a>, <a href="https://publications.waset.org/abstracts/search?q=Osifeko%20Christiana%20Osikorede"> Osifeko Christiana Osikorede</a>, <a href="https://publications.waset.org/abstracts/search?q=Folarin%20Bolanle%20Eunice"> Folarin Bolanle Eunice</a>, <a href="https://publications.waset.org/abstracts/search?q=Olugbenga%20Adebola%20Shodiya"> Olugbenga Adebola Shodiya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this period of economic problem, nations are looking for avenues to improve their economy, preserve their environment and socio-political environment, educational institutions are not left out as there is the need for them to increase their economy and preserve their socio political environment.

Based on the literature review, faculty development (i.e., academic or educational development) requires the continued adoption of cohesive, theoretical frameworks to guide research and practice; incorporation of relevant tools from analogous fields, such as teacher professional development; systematic program evaluations; and detailed descriptions of practice to further practice and creative development. A cohesive, five-heuristic framework is subsequently outlined to inform the design and evaluation of the use of digital video, so as to address the barriers to advancing faculty development, as identified through the literature review. Alternative impact evaluation approaches are also described, while the limitations of using digital video for faculty development are highlighted. This paper is therefore conceived as one way to meaningfully leverage the educational affordances of digital video to address some lingering gaps in faculty development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20video" title="digital video">digital video</a>, <a href="https://publications.waset.org/abstracts/search?q=faculty%2Feducational%20development" title=" faculty/educational development"> faculty/educational development</a>, <a href="https://publications.waset.org/abstracts/search?q=evaluation" title=" evaluation"> evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=scholarship%20of%20teaching%20and%20learning%20%28SoTL%29" title=" scholarship of teaching and learning (SoTL)"> scholarship of teaching and learning (SoTL)</a> </p> <a href="https://publications.waset.org/abstracts/51184/going-viral-constructively-aligning-the-use-of-digital-video-to-effectively-support-faculty-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51184.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">352</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Antimicrobial Potential of Calendula officinalis Extracts on Flavobacterium columnare of Clarias gariepinus Fingerlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Rotimi%20Osungbemiro">Nelson Rotimi Osungbemiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanni%20Rafiu%20Olugbenga"> Sanni Rafiu Olugbenga</a>, <a href="https://publications.waset.org/abstracts/search?q=Abayomi%20Olufemi%20Olajuyigbe"> Abayomi Olufemi Olajuyigbe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ninety Fingerlings of Clarias gariepinus were exposed to the pathogenic Flavobacterium columnare a Gram Negative bacteria responsible for high mortality in fish pond raised young fish (fries and fingerlings) of Clarias sp. in Southwestern Nigeria. After feeding with 40% crude protein pelletized fish feed for 5 days, the fishes were divided into two groups, one group was treated with extracts from Calendula officinalis flowers, while the second group was not treated (control). The results indicated that, at day 5, colony formation had been manifesting and at day 7, skin lesion occurred and at the 8th day, first mortality of fish occurred, and this continued steadily on the 9th-12th day when all the fishes were dead. Whereas, in the group that was treated with Calendula sp., no single mortality was recorded. This research shows that plant extract from Calendula flowers is an effective antimicrobial agent against the virulent pathogenic Flavobacterium columnare disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=Flavobacterium%20columnare" title=" Flavobacterium columnare"> Flavobacterium columnare</a>, <a href="https://publications.waset.org/abstracts/search?q=Clarias%20gariepinus" title=" Clarias gariepinus"> Clarias gariepinus</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a> </p> <a href="https://publications.waset.org/abstracts/25461/antimicrobial-potential-of-calendula-officinalis-extracts-on-flavobacterium-columnare-of-clarias-gariepinus-fingerlings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25461.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">608</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Catering for Children with Autism in the Regular Classroom: Challenges and the Way Forward</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beatrice%20Tayo%20Ajayi">Beatrice Tayo Ajayi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dzever%20Linus%20Terry"> Dzever Linus Terry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pupils with autism in the general classroom have dare need to be adequately catered for in social and academic activities for successful attainment in school work and future life. However, adequate catering for autistic children by teachers that basically received no training in content related to inclusive education and lack the ability to use inclusive strategies during classroom instruction appears to be a mirage. This paper intends to examine the current classroom environment in relation to the level to which autistic primary school pupils are catered for in the regular classroom. The study also seeks to identify the challenges teachers experience in the course of catering to the needs of children with autism and the way out. The sample consists of thirty (30) primary school teachers of Ondo West Local Government Area, Ondo State, Nigeria (10 male, 15 female), age grades between twenty five (25) to sixty (60). Data collection will be a survey using the researcher developed 18 statements Four Point- Likert Scale type to assess the level to which participants agree or disagree with the statement about catering for pupils with autism.

The reflection process involves examining the past and present to identify challenges, and culminates in the creation of an action plan to address barriers to further growth and teaching development of graduate students, thus positively impacting student experience. The outcomes of the reflective critique of the PFF program indicate that lack of mentoring as well as inadequate feedback and funding are barriers that need to be addressed to positively impact the graduate student experience. Consequently, interventions, such as peer and student evaluations, and alumni surveys are highlighted as pragmatic modes of addressing the inadequate feedback and mentoring barriers. However, funding remains an ongoing challenge. This article is a contribution to the literature on the use of critical reflection approaches to investigate and evaluate specific programming that focuses on enhancing the graduate student experience and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graduate%20student%20experience" title="graduate student experience">graduate student experience</a>, <a href="https://publications.waset.org/abstracts/search?q=longitudinal%20reflection" title=" longitudinal reflection"> longitudinal reflection</a>, <a href="https://publications.waset.org/abstracts/search?q=quality%20enhancement" title=" quality enhancement"> quality enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching" title=" teaching"> teaching</a> </p> <a href="https://publications.waset.org/abstracts/51183/reflections-on-ten-years-of-preparing-graduate-students-for-the-professoriate-at-an-american-research-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51183.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">265</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> Physicochemical and Bacteriological Quality Characterization of Some Selected Wells in Ado-Ekiti, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olu%20Ale">Olu Ale</a>, <a href="https://publications.waset.org/abstracts/search?q=Olugbenga%20Aribisala"> Olugbenga Aribisala</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanmi%20Awopetu"> Sanmi Awopetu </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater (Wells) is obtained from several well-defined and different water-bearing geological layers or strata. The physical, chemical and bacteriological quality of the water contributed from each of these water-bearing formations and resultant effects of indiscriminate wastes disposal will be dependent on the dissolution of material within the formation. Therefore, water withdrawn from any ground water source will be a composite of these individual aquifers. The water quality was determined by actual sampling and analysis of the completed wells. This study attempted to examine the physicochemical and bacteriological water quality of twenty five selected wells comprising twenty boreholes (deep wells) and five hand dug wells (shallow wells). The twenty five wells cut across the entire Ado Ekiti Metropolitan area. The water samples collected using standard method was promptly taken to water laboratory at the Federal Polytechnic Ado-Ekiti for analysis, physical, chemical and bacteriological tests were carried out. Quality characteristics tested were found to meet WHO’s standard and generally acceptable, making it potable for drinking in most situations, thus encouraging the use of groundwater. Possible improvement strategies to groundwater exploitation were highlighted while remedies to poor quality water were suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteriological" title="bacteriological">bacteriological</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical" title=" physicochemical"> physicochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=wells" title=" wells"> wells</a>, <a href="https://publications.waset.org/abstracts/search?q=Ado%20Ekiti" title=" Ado Ekiti"> Ado Ekiti</a> </p> <a href="https://publications.waset.org/abstracts/35884/physicochemical-and-bacteriological-quality-characterization-of-some-selected-wells-in-ado-ekiti-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35884.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">368</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> Evaluation of Massive Open Online Course in a Rural Marginalized Area: Case Study of Alice Community, 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=Dare%20Ebenezer%20Fatumo">Dare Ebenezer Fatumo</a>, <a href="https://publications.waset.org/abstracts/search?q=Olusesan%20Emmanuel%20Adelabu"> Olusesan Emmanuel Adelabu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Online learning has taken another dimension through the introduction of Massive Open Online Courses (MOOCs), it has also become an important resource base for teaching and learning.

This study concludes that MOOCs is a veritable medium for busy or less privileged individual to acquire a degree or certification. Therefore, the study recommends MOOCs platform to be fully embraced by people in rural marginalized areas, awareness programs about its usefulness should be propagated across the municipalities nationwide. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distance%20learning" title="distance learning">distance learning</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communication%20technology" title=" information and communication technology"> information and communication technology</a>, <a href="https://publications.waset.org/abstracts/search?q=massive%20open%20online%20course" title=" massive open online course"> massive open online course</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20learning" title=" online learning"> online learning</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20and%20learning" title=" teaching and learning"> teaching and learning</a> </p> <a href="https://publications.waset.org/abstracts/98901/evaluation-of-massive-open-online-course-in-a-rural-marginalized-area-case-study-of-alice-community-eastern-cape-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98901.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">29</span> Determinants of Integrated Reporting in Nigeria </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Uwalomwa%20Uwuigbe">Uwalomwa Uwuigbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Olubukola%20Ranti%20Uwuigbe"> Olubukola Ranti Uwuigbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinadu%20Olugbenga"> Jinadu Olugbenga</a>, <a href="https://publications.waset.org/abstracts/search?q=Otekunrin%20Adegbola"> Otekunrin Adegbola </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Corporate reporting has evolved over the years resulting from criticisms of the precedent by shareholders, stakeholders and other relevant financial institutions. Integrated reporting has become a globalized corporate reporting style, with its adoption around the world occurring rapidly to bring about an improvement in the quality of corporate reporting. While some countries have swiftly clinched into reporting in an integrated manner, others have not. In addition, there are ample research that has been conducted on the benefits of adopting integrated reporting, however, the same is not true in developing economies like Nigeria. Hence, this study basically examined the factors determining the adoption of integrated reporting in Nigeria. One hundred (100) copies of questionnaire was administered to financial managers of 20 selected listed companies in the Nigeria stock exchange market. The data obtained was analysed using the Spearman Rank Order Correlation via the Statistical Package for Social Science. This study observed that there is a significant relationship between the social pressures of isomorphic changes and integrated reporting adoption in Nigeria. The study recommends the need for an enforcement mechanism to be put in place while considering the adoption of integrated reporting in Nigeria, enforcement mechanisms should put into consideration the investors demand, the level of economic development, and the degree of corporate social responsibility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20social%20responsibility" title="corporate social responsibility">corporate social responsibility</a>, <a href="https://publications.waset.org/abstracts/search?q=isomorphic" title=" isomorphic"> isomorphic</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20reporting" title=" integrated reporting"> integrated reporting</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability "> sustainability </a> </p> <a href="https://publications.waset.org/abstracts/62690/determinants-of-integrated-reporting-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62690.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">390</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> Understanding Barriers to Sports Participation as a Means of Achieving Sustainable Development in Michael Otedola College of Primary Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Osifeko%20Olalekan%20Remigious">Osifeko Olalekan Remigious</a>, <a href="https://publications.waset.org/abstracts/search?q=Osifeko%20Christiana%20Osikorede"> Osifeko Christiana Osikorede</a>, <a href="https://publications.waset.org/abstracts/search?q=Folarin%20Bolanle%20Eunice"> Folarin Bolanle Eunice</a>, <a href="https://publications.waset.org/abstracts/search?q=Olugbenga%20Adebola%20Shodiya"> Olugbenga Adebola Shodiya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During these difficult economic times, nations are looking for ways to improve their finances, preserve the environment as well as the socio-political climate and educational institutions, which are needed to increase their economy and preserve their sustainable development.

The study used a qualitative research methodology with an exploratory research design. A sample of 12 mothers was used, comprising different racial backgrounds from low income areas in the Western Cape. The data was collected by means of semi-structured, in-depth interviews, which were transcribed verbatim, analysed using Braun’s and Clark’s (2006) six phases of thematic analysis. Some of the findings revealed that the mothers who participated in the study were consistently unable to feed their children and themselves due to profound and extreme situations of poverty, stress, and lack of infrastructural support. These mothers residing in low-income communities are not adequately supported both financially and socially and are often unable to meet the needs of their infants within the first 1000 days. Given the consequential nature of this period, it is imperative that mothers are able to access such support. Single mothers especially are in need of social and financial support. Appropriate interventions are required to assist mothers generally but more specifically, mothers who have children within the first 1000 days of life. By implementing appropriate interventions to address these needs, it will assist mothers to ensure optimal developmental growth of their children. This will positively impact the developmental trajectory of children in South Africa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=caring" title="caring">caring</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20hardship" title=" economic hardship"> economic hardship</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20one%20thousand%20days" title=" first one thousand days"> first one thousand days</a>, <a href="https://publications.waset.org/abstracts/search?q=mothers" title=" mothers"> mothers</a> </p> <a href="https://publications.waset.org/abstracts/109146/first-1000-days-of-life-mothers-economic-hardship-of-caring-for-their-babies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109146.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">133</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> Effects of Air Pollution on Dew Water: A Case Study of Ado-Ekiti, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sanmi%20Awopetu">M.

Earth is getting warmer; ozone layer is getting depleted, acid rain is being experienced, all as a result of air pollution. This study seeks to investigate the effect of air pollution on dew water. Thirty-one (31) samples of dew water were collected in four locations in Ado- Ekiti, Ekiti State Nigeria. Analytical studies of the dew water samples were carried out to determine the pH, Total Dissolved Solids (TDS) and Electrical Conductivity (EC) in order to determine whether the dew water is polluted or not. There is no documented world standard for dew water quality. However, the standard for normal rain water which is pH between 5.0-5.6 and acid rain pH between 4.0-4.4 was adopted for this study. The pH of dew water samples collected and analyzed ranged between 5.5 and 7.9 in Olokun Ado-Ekiti while other samples fell in between this range. In Government Reserved Area (GRA), Ajilosun and EKSU school area, the pH ranged between 6.4 and 7.9 while EC fell in between 0.0 and 0.9 mS/cm which shows that the observed zones are polluted. Everyone has a role to play in order to reduce the pollutants being released into the atmosphere. There is a need to develop an international standard for dew water quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dew" title="dew">dew</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20pollution" title=" air pollution"> air pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20dissolved%20solids" title=" total dissolved solids"> total dissolved solids</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Ado-Ekiti" title=" Ado-Ekiti"> Ado-Ekiti</a> </p> <a href="https://publications.waset.org/abstracts/83876/effects-of-air-pollution-on-dew-water-a-case-study-of-ado-ekiti-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83876.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">194</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Sexual Health and Sexual Risk Behavior of the Youth with HIV Positive in Northeastern Part, Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Orathai%20Srithongtham">Orathai Srithongtham</a>, <a href="https://publications.waset.org/abstracts/search?q=Ubonsri%20Thabuddha"> Ubonsri Thabuddha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The youth with HIV positive is not difference from the general youth in term of sexual needs. Sexual health is crucial the most to support the youth with HIV positive to be sexual well-being. This study aims to elucidate the sexual health on protection from STDs (Sexual Transmitted Diseases) and HIV transmission and to explain sexual risk behavior of the youth with HIV positive. The target group was the youth with HIV positive about 23 cases from two provinces in northeastern part of Thailand. Qualitative method was applied for collecting data by in-depth interview. Content analysis was use for data analysis. The youth with HIV positive was protection from STDs and HIV transmission by using the condom during sexual activity. The reason to deny the condom use were ashamed, condom is not a part of life, no have fit size, and the youth fear to stigmatized as a mental disorder and fear to stigmatized as going to fuck someone. The youth who trust with nurse in clinic was dare to request the condom by face. Sexual activity without condom use is sexual risk behavior. The major causes were couple trust and the sexual enjoyment first and sexual active competition with friend without condom use. The concern on HIV was the boyfriend or girlfriend not accepts the HIV positive people, worry about the HIV transmutation, and finally not compliance to ARV drug. The youth with HIV positive was lacking of the knowledge on sexual health on the issues of access to condom and the concern to keep on relationship with the boyfriend or girlfriend. This concern issues was led to the non-adherence of ARV drug and HIV distribution. To provide the sexual health service is more essential to the youth with HIV positive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexual%20health" title="sexual health">sexual health</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20risk%20behavior" title=" sexual risk behavior"> sexual risk behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=youth" title=" youth"> youth</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV "> HIV </a> </p> <a href="https://publications.waset.org/abstracts/35614/sexual-health-and-sexual-risk-behavior-of-the-youth-with-hiv-positive-in-northeastern-part-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35614.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">477</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> Finite Difference Modelling of Temperature Distribution around Fire Generated Heat Source in an Enclosure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20Dare">A.

The fire leads to temperature distribution inside the enclosure. A proper understanding of the temperature and velocity distribution within the enclosure is often required for optimal design and use of the furnace. This study was therefore directed at numerical modeling of temperature distribution inside an enclosure as typical in a furnace. A mathematical model was developed from the conservation of mass, momentum and energy. The stream function-vorticity formulation of the governing equations was solved by an alternating direction implicit (ADI) finite difference technique. The finite difference formulation obtained were then developed into a computer code. This was used to determine the temperature, velocities, stream function and vorticity. The effect of the wall heat conduction was also considered, by assuming a one-dimensional heat flow through the wall. The computer code (MATLAB program) developed was used for the determination of the aforementioned variables. The results obtained showed that the transient temperature distribution assumed a uniform profile which becomes more chaotic with increasing time. The vertical velocity showed increasing turbulent behavior with time, while the horizontal velocity assumed decreasing laminar behavior with time. All of these behaviours were equally reported in the literature. The developed model has provided understanding of heat transfer process in an industrial furnace. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20source" title="heat source">heat source</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=enclosure" title=" enclosure"> enclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=furnace" title=" furnace"> furnace</a> </p> <a href="https://publications.waset.org/abstracts/11099/finite-difference-modelling-of-temperature-distribution-around-fire-generated-heat-source-in-an-enclosure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11099.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">255</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> Estimation of Effective Radiation Dose Following Computed Tomography Urography at Aminu Kano Teaching Hospital, Kano Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Idris%20Garba">Idris Garba</a>, <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Rabiu%20Abdullahi"> Aisha Rabiu Abdullahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansur%20Yahuza"> Mansur Yahuza</a>, <a href="https://publications.waset.org/abstracts/search?q=Akintade%20Dare"> Akintade Dare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: CT urography (CTU) is efficient radiological examination for the evaluation of the urinary system disorders. However, patients are exposed to a significant radiation dose which is in a way associated with increased cancer risks. Objectives: To determine Computed Tomography Dose Index following CTU, and to evaluate organs equivalent doses. Materials and Methods: A prospective cohort study was carried at a tertiary institution located in Kano northwestern. Ethical clearance was sought and obtained from the research ethics board of the institution. Demographic, scan parameters and CT radiation dose data were obtained from patients that had CTU procedure. Effective dose, organ equivalent doses, and cancer risks were estimated using SPSS statistical software version 16 and CT dose calculator software. Result: A total of 56 patients were included in the study, consisting of 29 males and 27 females. The common indication for CTU examination was found to be renal cyst seen commonly among young adults (15-44yrs). CT radiation dose values in DLP, CTDI and effective dose for CTU were 2320 mGy cm, CTDIw 9.67 mGy and 35.04 mSv respectively. The probability of cancer risks was estimated to be 600 per a million CTU examinations. Conclusion: In this study, the radiation dose for CTU is considered significantly high, with increase in cancer risks probability. Wide radiation dose variations between patient doses suggest that optimization is not fulfilled yet. Patient radiation dose estimate should be taken into consideration when imaging protocols are established for CT urography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CT%20urography" title="CT urography">CT urography</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20risks" title=" cancer risks"> cancer risks</a>, <a href="https://publications.waset.org/abstracts/search?q=effective%20dose" title=" effective dose"> effective dose</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20exposure" title=" radiation exposure"> radiation exposure</a> </p> <a href="https://publications.waset.org/abstracts/61467/estimation-of-effective-radiation-dose-following-computed-tomography-urography-at-aminu-kano-teaching-hospital-kano-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61467.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">22</span> Assessment of in vitro Antioxidant and Anti-Inflammatory Potentials of Methanol Extract of Chrysophyllum albidum Cotyledon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christianah%20Adebimpe%20Dare">Christianah Adebimpe Dare</a>, <a href="https://publications.waset.org/abstracts/search?q=Nelson%20Oghenebrorhie%20Elvis"> Nelson Oghenebrorhie Elvis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was aimed at analysing the phytochemicals in Chrysophyllum albidum cotyledon extract and their in vitro antioxidant and anti-inflammatory effects. The star apple fruit was bought at Igbona market Osogbo, Osun State, Nigeria. The seed from the fruit was removed and defatted. The residue was exhaustively extracted with methanol. The Chrysophyllum albidum cotyledon methanol extract (CCME) was phytochemically screened, flavonoids and phenol contents, antioxidant and anti-inflammatory assays were carried out on the extract using standard procedures. Phytochemicals analysis revealed the presence of steroids, tannins, flavonoid, saponin, triterpenes, and xanthoproteins. The phenolic concentration, total flavonoids concentration, and total sugar concentration were found to be 26.72 ± 0.048 µgTAE/mg, 23.12 ± 1.92µg of Rutin equivalent (RTE)/mg (10.49 ± 1.12µg of Quercetin equivalent (QE/mg) and 778.38 ± 12.82 µg of glucose/ml, respectively. The extract demonstrated significant inhibitory effect compared with the standards as potent antioxidant with percentage inhibition of DPPH as 38.10 %-39.51 %, lipid peroxidation as 45.85 %-65.85 %; ferric reducing power showed linear correlation to the standard and the anti-inflammatory potential with 22.06 %-26.37 % protection of the human red blood membrane and the percentage inhibition of denaturation of albumin 3.42 %-7.32 %. The study showed that C. albidum cotyledon methanol extract is a potent antioxidant and anti-inflammatory agent to combat oxidative stress and pathological diseases caused by reactive species. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=albumin%20denaturation" title="albumin denaturation">albumin denaturation</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20radicals" title=" free radicals"> free radicals</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20species" title=" reactive species"> reactive species</a> </p> <a href="https://publications.waset.org/abstracts/125612/assessment-of-in-vitro-antioxidant-and-anti-inflammatory-potentials-of-methanol-extract-of-chrysophyllum-albidum-cotyledon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125612.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">21</span> Effects of Titanium Dioxide Coatings on Building Composites for Sustainable Construction Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ifeyinwa%20Ijeoma%20Obianyo">Ifeyinwa Ijeoma Obianyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Luqman%20Adedeji%20Taiwo"> Luqman Adedeji Taiwo</a>, <a href="https://publications.waset.org/abstracts/search?q=Olugbenga%20O.%20Amu"> Olugbenga O.

In this study, titanium dioxide coated conventional and non-conventional composites were produced, and the effects of titanium dioxide coatings were investigated. Conventional composites were produced using river sand and Portland cement, whereas non-conventional composites were produced by partially replacing river sand and Portland cement with quarry dust and rice husk ash. Water absorption and thickness swelling tests were conducted on the produced coated and non-coated block samples. A reduction in water absorption was observed in the coated composite samples when compared to the non-coated composite samples, and this is an indication of the improved durability of the samples coated with titanium dioxide. However, there was an increase in the thickness swelling of coatings on the coated block samples, but this increase has a slight influence on the compressive strength of the coated samples. The outcome of this study indicates that coating composite building blocks with titanium dioxide will improve theirdurability. Also, the site exposure experiments revealed the self-cleansing properties of TiO2-coated composite block samples, while the Rhodamine B discolouration test confirmed the photocatalytic features of TiO2-coated composite block samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20dioxide" title="titanium dioxide">titanium dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption" title=" water absorption"> water absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=durability" title=" durability"> durability</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20composite" title=" building composite"> building composite</a> </p> <a href="https://publications.waset.org/abstracts/156859/effects-of-titanium-dioxide-coatings-on-building-composites-for-sustainable-construction-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156859.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">113</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> Study on the Effect of Weather Variables on the Spider Abundance in Two Ecological Zones of Ogun State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Odejayi%20Adedayo%20Olugbenga">Odejayi Adedayo Olugbenga</a>, <a href="https://publications.waset.org/abstracts/search?q=Aina%20Adebisi"> Aina Adebisi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Weather variables (rainfall and temperature) affect the diversity and abundance of both fauna and flora species. This study compared the weather variables with spider abundance in two ecological zones of Ogun State, Nigeria namely Ago-iwoye (Rainforest) in the Ijebu axis and Aiyetoro (Derived Savannah) in the Yewa axis. Seven study sites chosen by Simple Random Sampling in each ecosystem were used for the study. In each sampling area, a 60 m x 120 m land area was marked and sampled, spider collection techniques were; hand picking, use of sweep netting, and Pitfall trap. Adult spiders were identified to the species level. Species richness was estimated by a non-parametric species estimator while the diversity of spider species was assessed by Simpson Diversity Index and Species Richness by One-way Analysis of Variance. Results revealed that spiders were more abundant in rainforest zones than in derived savannah ecosystems. However, the pattern of spider abundance in rainforest zone and residential areas were similar. During high temperatures, the activities of spiders tended to increase according to this study. In contrast, results showed that there was a negative correlation between rainfall and spider species abundance in addition to a negative and weak correlation between rainfall and species richness. It was concluded that heavy downpour has lethal effects on both immature and sometimes matured spiders, which could lead to the extinction of some unknown species of spiders. Tree planting should be encouraged, as this shelters the spider. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spider" title="spider">spider</a>, <a href="https://publications.waset.org/abstracts/search?q=abundance" title=" abundance"> abundance</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20richness" title=" species richness"> species richness</a>, <a href="https://publications.waset.org/abstracts/search?q=species%20diversity" title=" species diversity"> species diversity</a> </p> <a href="https://publications.waset.org/abstracts/168175/study-on-the-effect-of-weather-variables-on-the-spider-abundance-in-two-ecological-zones-of-ogun-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168175.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">92</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 the Determinants of Boko Haram Terrorism in Nigerian Security Systems and Economy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abara%20Onu">Abara Onu</a>, <a href="https://publications.waset.org/abstracts/search?q=Augustine%20Mina%20Ephraim"> Augustine Mina Ephraim</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20%20Teidi"> Emmanuel Teidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Terrorism has been a major challenge and is so dare to the Nigerian government in recent times. The actions and activities of the Islamic sect known as Boko Haram had led to enormous loss of lives and properties in the country, mostly the Northern part of Nigeria. Some of these activities entails bombings, suicide attacks, intimidations, sporadic gunfire of the unarmed, blameless and innocent Nigerians, burning of police stations and churches, kidnappings, raping of school girls and women. Nigeria has also been included amongst one of the terrorist countries of the world. This has serious implications for the development of Nigerian economy. Although, Nigeria had made several worried hard work to deal with these challenges masqueraded by terrorism and insecurity in the country but the rate of insurgency and insecurity is still worrisome. The study looks at exploring the determinants of Boko Haram terrorism in Nigerian security systems and economy. Data used for the study work was from questionnaire administered, using Analysis of Variance (ANOVA) method to analyse the data. The result shows that Ideology and funding are significant basic factors that propelled the Boko Haram group in Nigeria. The Boko Haram disaster poses a significant threat to Nigeria’s economy and the military is the best option and solution in tackling the Boko Haram menace in Nigeria. The work x-rayed the following recommendations; government should declare war on terrorism and as well seek support and cooperation from international communities who in time or the other might have faced with this kind ugly experience and challenge and were able to tackle it. Nigerian Military needs to be more empowered with high dangerous weapons to combat the insurgency as well as beef up security across the Country to curb the threats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=terrorism" title="terrorism">terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=economy" title=" economy"> economy</a>, <a href="https://publications.waset.org/abstracts/search?q=Boko%20Haram" title=" Boko Haram"> Boko Haram</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a> </p> <a href="https://publications.waset.org/abstracts/71878/exploring-the-determinants-of-boko-haram-terrorism-in-nigerian-security-systems-and-economy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71878.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">261</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> Facile Synthesis and Characterization of Heterostructure Core-Shell Silver-Silica Nanocomposite for Humidity Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatai%20O.%20Oladoyinbo">Fatai O.

X-ray Diffraction (XRD), High-Resolution Transmission Electron Microscopy (HRTEM), Scanning Electron Microscopy (SEM), Uv-Visible spectroscopy, Energy Dispersive X-ray (EDX) spectroscopy and N2 adsorption-desorption techniques were utilized to characterize the composition and structure of the samples. The crystallinity pattern of Ag nanoparticles was indexed as (111), (200), (220) and (311), which allowed reflections from face-centered cubic silver. XRD of SiO2 showed good porosity with a broad-spectrum band at Bragg’s angle 2θ of 22° while that of Ag-SiO2 showed distinct peaks at 2θ values of 39°, 43°, 66° and 79°. The XRD result agreed perfectly with the SEM and HRTEM images which showed Ag-SiO2 isotropic and anisotropic under the varying concentration of reactants. The elemental composition of Ag-SiO2, as displayed by EDX, confirmed Ag enrichment in the Ag-SiO2 heterostructure. The Uv-Visible peak at 421 nm confirmed the Surface Plasmon Resonance absorption peak of silver nanoparticles. N2 adsorption-desorption result showed a broad band of Ag-SiO2 from 3 to 8 nm, which indicated relatively narrow pore size distributions. Humidity sensing measurements performed in a controlled humidity chamber showed very high sensitivity with a sensitivity factor (SF) of 4.63 and high linearity with a steady decrease in resistance to humidity from 880 Ω at 10% RH to 190 Ω at 100% RH, indicating that Ag-SiO2 nanocomposite is a good sensing material with high sensitivity and linearity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=silver" title="silver">silver</a>, <a href="https://publications.waset.org/abstracts/search?q=silica" title=" silica"> silica</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=heterostructure" title=" heterostructure"> heterostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20shell" title=" core shell"> core shell</a> </p> <a href="https://publications.waset.org/abstracts/165614/facile-synthesis-and-characterization-of-heterostructure-core-shell-silver-silica-nanocomposite-for-humidity-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165614.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">77</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> Detection and Expression of Peroxidase Genes in Trichoderma harzianum KY488466 and Its Response to Crude Oil Degradation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Dare%20Asemoloye">Michael Dare Asemoloye</a>, <a href="https://publications.waset.org/abstracts/search?q=Segun%20Gbolagade%20Jonathan"> Segun Gbolagade Jonathan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafiq%20Ahmad"> Rafiq Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Odunayo%20Joseph%20Olawuyi"> Odunayo Joseph Olawuyi</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20O.%20Adejoye"> D.

Crude oil tolerance and degradation by Trichoderma harzianum was investigated in this study with its ability to produce peroxidase enzymes (LiP and MnP). Many fungal strains were isolated from rhizosphere of grasses growing on a crude oil spilled site, and the most frequent strain based on percentage incidence was further characterized using morphological and molecular characteristics. Molecular characterization was done through the amplification of Ribosomal-RNA regions of 18s (1609-1627) and 28s (287-266) using ITS1 and ITS4 combinations and it was identified using NCBI BLAST tool. The selected fungus was also subjected to an in-vitro tolerance test at crude oil concentrations of 5, 10, 15, 20 and 25% while 0% served as control. In addition, lignin peroxidase genes (lig1-6) and manganese peroxidase gene (mnp) were detected and expressed in this strain using RT-PCR technique, its peroxidase producing activities was also studied in aliquots (U/ml). This strain had highest incidence of 80%, it was registered in NCBI as Trichoderma harzianum asemoJ KY488466. The strain KY488466 responded to crude oil concentrations as it increase, the dose inhibition response percentage (DIRP) increased from 41.67 to 95.41 at 5 to 25 % crude oil concentrations. All the peroxidase genes are present in KY488466, and expressed with amplified 900-1000 bp through RT-PCR technique. In this strain, lig2, lig4 and mnp genes were over-expressed, lig 6 was moderately expressed, while none of the genes was under-expressed. The strain also produced 90±0.87 U/ml lignin peroxidase and 120±1.23 U/mil manganese peroxidase enzymes in aliquots. These results imply that KY488466 can tolerate and survive high crude oil concentration and could be exploited for bioremediation of oil-spilled soils, the produced peroxidase enzymes could also be exploited for other biotechnological experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crude%20oil" title="crude oil">crude oil</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymes" title=" enzymes"> enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=expression" title=" expression"> expression</a>, <a href="https://publications.waset.org/abstracts/search?q=peroxidase%20genes" title=" peroxidase genes"> peroxidase genes</a>, <a href="https://publications.waset.org/abstracts/search?q=tolerance" title=" tolerance"> tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=Trichoderma%20harzianum" title=" Trichoderma harzianum"> Trichoderma harzianum</a> </p> <a href="https://publications.waset.org/abstracts/77759/detection-and-expression-of-peroxidase-genes-in-trichoderma-harzianum-ky488466-and-its-response-to-crude-oil-degradation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77759.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">228</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> Perceived Impact of Climate Change on the Livelihood of Arable Crop Farmers in Ipokia Local Government Area of Ogun State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Olugbenga%20Fakoya">Emmanuel Olugbenga Fakoya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study examined the perceived impact of climate change on the livelihood of arable crop farmers in Ipokia Local Government Area of Ogun State, Nigeria. Multistage sampling technique was used to select 80 arable crop farmers in the study area. Data collected were analyzed using percentages, frequencies and Chi square analysis. The result showed that 63.8 percent of the respondents were male while 55.0 percent were married. Less than half (30.0 percent) of the respondents were between the age bracket of 41-50 years and 50.0 percent had 6-10 household size. Furthermore, majority (40.0 percent) of the arable crop farmers farmed on an inherited land and 51.3 percent had 2-3 hectares of land. Majority (38.8 percent) of the farmers intercrop maize with cassava and maize with yam. Various strategies adapted to reduce the effect of climate change on their crop and livelihood include: crop rotation (53.8 percent), planting of leguminous crop (35.0 percent), application of organic fertilizers (45.0 percent), mulching (56.3 percent) and by planting drought resistance crops (46.5 percent). Reported among the effects of climate change on crop and farmers’ livelihood were: discoloration of crop leave (63.8 percent), increase infestation of pests and diseases (58.8 percent) and reduction of crop yield (60.0 percent). Chi- square analysis showed significant relationship between impact of climate change on arable crop production and thus famers’ livelihood. It was concluded from the study that climate change is an impinging factor that seriously affect arable crop production and hence farmers’ livelihood despite coping strategies to minimize its effect. It was however recommended that Agricultural policies and practices that could minimize or eliminate its effect should be seriously enacted to boost production and increase farmers’ livelihood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agricultural%20extension" title="agricultural extension">agricultural extension</a>, <a href="https://publications.waset.org/abstracts/search?q=extension%20agent" title=" extension agent"> extension agent</a>, <a href="https://publications.waset.org/abstracts/search?q=private%20sector" title=" private sector"> private sector</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a> </p> <a href="https://publications.waset.org/abstracts/12502/perceived-impact-of-climate-change-on-the-livelihood-of-arable-crop-farmers-in-ipokia-local-government-area-of-ogun-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12502.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">444</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> Petrogenesis of the Neoproterozoic Rocks of Megele Area, Asosa, Western Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temesgen%20Oljira">Temesgen Oljira</a>, <a href="https://publications.waset.org/abstracts/search?q=Olugbenga%20Akindeji%20Okunlola"> Olugbenga Akindeji Okunlola</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinade%20Shadrach%20Olatunji"> Akinade Shadrach Olatunji</a>, <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Ayalew"> Dereje Ayalew</a>, <a href="https://publications.waset.org/abstracts/search?q=Bekele%20Ayele%20Bedada"> Bekele Ayele Bedada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Western Ethiopian Shield (WES) is underlain by volcano-sedimentary terranes, gneissic terranes, and ophiolitic rocks intruded by different granitoid bodies. For the past few years, Neoproterozoic rocks of the Megele area in the western part of the WES have been explored. Understanding the geology of the area and assessing the mineralized area's economic potential requires petrological, geochemical, and geological characterization of the Neoproterozoic granitoids and associated metavolcanic rocks. Thus, the geological, geochemical, and petrogenetic features of Neoproterozoic granitoids and associated metavolcanic rocks were elucidated using a combination of field mapping, petrological, and geochemical study. The Megele area is part of a low-grade volcano-sedimentary zone that has been intruded by mafic (dolerite dyke) and granitoid intrusions (granodiorite, diorite, granite gneiss). The granodiorite, associated diorite, and granite gneiss are calc-alkaline, peraluminous to slightly metaluminous, S-type granitoids formed in volcanic arc subduction (VAG) to syn-collisional (syn-COLD) tectonic setting by fractionation of LREE-enriched, HREE-depleted basaltic magma with considerable crustal input. While the metabasalt is sub-alkaline (tholeiitic), metaluminous bodies are generated at the mid-oceanic ridge tectonic setting by partially melting HREE-depleted and LREE-enriched basaltic magma. The reworking of sediment-loaded crustal blocks at depth in a subduction zone resulted in the production of S-type granitoids. This basaltic magma was supplied from an LREE-enriched, HREE-depleted mantle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractional%20crystallization" title="fractional crystallization">fractional crystallization</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemistry" title=" geochemistry"> geochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=Megele" title=" Megele"> Megele</a>, <a href="https://publications.waset.org/abstracts/search?q=petrogenesis" title=" petrogenesis"> petrogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=s-type%20granite" title=" s-type granite"> s-type granite</a> </p> <a href="https://publications.waset.org/abstracts/149624/petrogenesis-of-the-neoproterozoic-rocks-of-megele-area-asosa-western-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149624.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">129</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> Oxygen and Sulfur Isotope Composition of Gold Bearing Granite Gneiss and Quartz Veins of Megele Area, Western Ethiopia: Implication for Fluid Source</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temesgen%20Oljira">Temesgen Oljira</a>, <a href="https://publications.waset.org/abstracts/search?q=Olugbenga%20Akindeji%20Okunlola"> Olugbenga Akindeji Okunlola</a>, <a href="https://publications.waset.org/abstracts/search?q=Akinade%20Shadrach%20Olatunji"> Akinade Shadrach Olatunji</a>, <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Ayalew"> Dereje Ayalew</a>, <a href="https://publications.waset.org/abstracts/search?q=Bekele%20A.%20Bedada"> Bekele A.

The geochemical and ore petrological characterization of the gold-bearing granite gneiss and associated quartz vein is crucial in understanding the gold's genesis. The present study concerns the ore petrological, geochemical, and stable O2 and S characterization of the gold-bearing granite gneiss and associated quartz vein. This area is known for its long history of placer gold mining. The presence of quartz veins of different generations and orientations, visible sulfide mineralization, and oxidation suggests that the Megele area is geologically fertile for mineralization. The Au and base metals analysis also indicate that Megele area rocks are characterized by Cu (2-22 ppm av. 7.83 ppm), Zn (2-53 ppm av. 29.33 ppm), Co (1-27 ppm av. 13.33 ppm), Ni (2-16 ppm av. 10 ppm), Pb (5-10 ppm av. 8.33 ppm), Au (1-5 ppb av. 2.11 ppb), Ag (0.5 ppm), As (5-12 ppm av. 7.83 ppm), Cd (0.5ppm), Li (0.5 ppm), Mo (1-4 ppm av. 1.6 ppm), Sc (5-13 ppm av. 9.3 ppm), and Tl (10 ppm). The oxygen isotope (δ18O) values of gold-bearing granite gneiss and associated quartz veins range from +8.6 to +11.5 ‰, suggesting the mixing of metamorphic water with magmatic water within the ore-forming fluid. The Sulfur isotope (δ34S) values of gold-bearing granite gneiss range from -1.92 to -0.45 ‰ (mean value of -1.13 ‰) indicating the narrow range of value. This suggests that the sulfides have been precipitated from the fluid system originating from a single source of the magmatic component under sulfur isotopic fractionation equilibrium condition. The tectonic setting of the host rocks, the occurrence of ore bodies, mineral assemblages of the host rocks and proposed ore-forming fluids of the Megele area gold prospects have similarities with features of orogenic gold deposit. The δ18O and δ34S isotopic values also suggested a metamorphic origin with the magmatic components. Thus, the Megele gold prospect could be related to an orogenic gold deposit related to metamorphism and associated intrusions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid%20source" title="fluid source">fluid source</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%20mineralization" title=" gold mineralization"> gold mineralization</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen%20isotope" title=" oxygen isotope"> oxygen isotope</a>, <a href="https://publications.waset.org/abstracts/search?q=stable%20isotope" title=" stable isotope"> stable isotope</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20isotope" title=" sulfur isotope"> sulfur isotope</a> </p> <a href="https://publications.waset.org/abstracts/169023/oxygen-and-sulfur-isotope-composition-of-gold-bearing-granite-gneiss-and-quartz-veins-of-megele-area-western-ethiopia-implication-for-fluid-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169023.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">73</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> Pervasive Computing: Model to Increase Arable Crop Yield through Detection Intrusion System (IDS)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Idowu%20Olugbenga%20Adewumi">Idowu Olugbenga Adewumi</a>, <a href="https://publications.waset.org/abstracts/search?q=Foluke%20Iyabo%20Oluwatoyinbo"> Foluke Iyabo Oluwatoyinbo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Presently, there are several discussions on the food security with increase in yield of arable crop throughout the world. This article, briefly present research efforts to create digital interfaces to nature, in particular to area of crop production in agriculture with increase in yield with interest on pervasive computing. The approach goes beyond the use of sensor networks for environmental monitoring but also by emphasizing the development of a system architecture that detect intruder (Intrusion Process) which reduce the yield of the farmer at the end of the planting/harvesting period. The objective of the work is to set a model for setting up the hand held or portable device for increasing the quality and quantity of arable crop. This process incorporates the use of infrared motion image sensor with security alarm system which can send a noise signal to intruder on the farm. This model of the portable image sensing device in monitoring or scaring human, rodent, birds and even pests activities will reduce post harvest loss which will increase the yield on farm. The nano intelligence technology was proposed to combat and minimize intrusion process that usually leads to low quality and quantity of produce from farm. Intranet system will be in place with wireless radio (WLAN), router, server, and client computer system or hand held device e.g PDAs or mobile phone. This approach enables the development of hybrid systems which will be effective as a security measure on farm. Since, precision agriculture has developed with the computerization of agricultural production systems and the networking of computerized control systems. In the intelligent plant production system of controlled greenhouses, information on plant responses, measured by sensors, is used to optimize the system. Further work must be carry out on modeling using pervasive computing environment to solve problems of agriculture, as the use of electronics in agriculture will attracts more youth involvement in the industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pervasive%20computing" title="pervasive computing">pervasive computing</a>, <a
