A public-public partnership (PUP) is a partnership between two or more public authorities or between a public authority and any non-profit organization with the goal of providing services and facilities or transferring technical skills. The paper presents this kind of partnership between two public authorities in Macedonia, the Municipality of Gazi Baba on one hand, and the University of Goce Delcev on the other. The main idea of this partnership is the development of a tourism strategy for the Municipality of Gazi Baba by the University on one side, and on the other, the construction of a mini park in the court of the University by the Municipality. This paper presents the causes and analyzes the procedures relating to this partnership and the methodology of the tourism development strategy. It contains a relevant literature review related to PUPs and tourism development strategy. The results and benefits of this partnership are presented with figures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public-public%20partnership" title="public-public partnership">public-public partnership</a>, <a href="https://publications.waset.org/abstracts/search?q=tourism%20development%20strategy" title=" tourism development strategy"> tourism development strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=municipality%20of%20Gazi%20Baba" title=" municipality of Gazi Baba"> municipality of Gazi Baba</a>, <a href="https://publications.waset.org/abstracts/search?q=Macedonia" title=" Macedonia"> Macedonia</a> </p> <a href="https://publications.waset.org/abstracts/69350/public-public-partnership-and-tourism-development-strategy-the-case-of-municipality-of-gazi-baba-in-macedonia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69350.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">362</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> In Vivo Maltase and Sucrase Inhibitory Activities of Five Underutilized Nigerian Edible Fruits</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Auwal%20Ibrahim">Mohammed Auwal Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Isa%20Yunusa"> Isa Yunusa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafisa%20Kabir"> Nafisa Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Shazali%20Ali%20Baba"> Shazali Ali Baba</a>, <a href="https://publications.waset.org/abstracts/search?q=Amina%20Muhammad%20Yushau"> Amina Muhammad Yushau</a>, <a href="https://publications.waset.org/abstracts/search?q=Suraj%20Suraj%20Ibrahim"> Suraj Suraj Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaharaddeen%20Idris%20Bello"> Zaharaddeen Idris Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Suleiman%20Haruna%20Suleiman"> Suleiman Haruna Suleiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Murtala%20Bindawa%20Isah"> Murtala Bindawa Isah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Inhibition of intestinal maltase and sucrase prevents postprandial blood glucose excursions which are beneficial in ameliorating diabetes-associated complications. Objective: In this study, the inhibitory effects of fruit extracts of Parinari macrophylla, Detarium microcarpum, Ziziphus spina-christi, Z. mairei and Parkia biglobosa were investigated against intestinal maltase and sucrase. Methods: Rats were given co-administration of the fruit extracts with maltose or sucrose and blood glucose levels were measured at 0, 30, 90 and 120 min. Results: The glucose-time curves indicated that all the fruits had the most potent inhibitory effects on both maltase and sucrase within the first 30 min. The computed Area Under the Curves (AUC0-120)for all the fruits indicated more potent inhibitory effects against intestinal maltase than sucrase.The ED50 range for the fruits extract against maltase and sucrase were 647.15-1118.35 and 942.44-1851.94 mg/kg bw respectively. Conclusion: The data suggests that the fruits could prevent postprandial hyperglycemia via inhibition of intestinal maltase and sucrase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=fruits" title=" fruits"> fruits</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B1-glucosidases" title=" α-glucosidases"> α-glucosidases</a>, <a href="https://publications.waset.org/abstracts/search?q=maltase" title=" maltase"> maltase</a>, <a href="https://publications.waset.org/abstracts/search?q=sucrase" title=" sucrase"> sucrase</a> </p> <a href="https://publications.waset.org/abstracts/43113/in-vivo-maltase-and-sucrase-inhibitory-activities-of-five-underutilized-nigerian-edible-fruits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43113.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">383</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">43</span> Gender and Political Participation in Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Baba">Ibrahim Baba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work examines the nature and causes of differential politics in Africa with particular reference to the sub-Saharan region of the continent.

Companies are advised by accounting bodies to enhance IC disclosure which complements the conventional financial disclosures. There are no accounting standards for Intellectual Capital Disclosure (ICD), therefore the disclosure is entirely voluntary. Hence, this study aims to investigate the extent of ICD and to examine the relationship between corporate governance and ICD in Malaysia. This study employed content analysis of 100 annual reports by the top 100 public listed companies in Malaysia during 2012. The uniqueness of this study lies on its underpinning theory used where it applies the institutional isomorphism theory to support the effect of the attributes of corporate governance towards ICD. In order to achieve the stated objective, multiple regression analysis were employed to conduct this study. From the descriptive statistics, it was concluded that public listed companies in Malaysia have increased their awareness towards the importance of ICD. Furthermore, results from the multiple regression analysis confirmed that corporate governance affects the company’s ICD where the frequency of audit committee meetings and the board size has positively influenced the level of ICD in companies. Findings from this study would provide an incentive for companies in Malaysia to enhance the disclosure of IC. In addition, this study would assist Bursa Malaysia and other regulatory bodies to come up with a proper guideline for the disclosure of IC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=annual%20report" title="annual report">annual report</a>, <a href="https://publications.waset.org/abstracts/search?q=content%20analysis" title=" content analysis"> content analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=intellectual%20capital%20disclosure" title=" intellectual capital disclosure"> intellectual capital disclosure</a> </p> <a href="https://publications.waset.org/abstracts/70158/the-relationship-between-corporate-governance-and-intellectual-capital-disclosure-malaysian-evidence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70158.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Polygenetic Iron Mineralization in the Baba-Ali and Galali Deposits, Further Evidences from Stable (S, O, H) Isotope Data, NW Hamedan, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghodratollah%20Rostami%20Paydar">Ghodratollah Rostami Paydar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Baba-Ali and Galali iron deposits are located in northwest Hamedan and the Iranian Sanandaj-Sirjan geological structural zone. The host rocks of these deposits are metavolcanosedimentary successions of Songhor stratigraphic series with permo-trriassic age. Field investigation, ore geometry, textures and structures and paragenetic sequence of minerals, all indicate that the ore minerals are crystallized in four stages: primary volcanosedimentary stage, secondary regional metamorphism with formation of ductile shear zones, contact metamorphism and metasomatism stage and the finally late hydrothermal mineralization within uplift and exposure. Totally 29 samples of sulfide, oxide-silicate and carbonate minerals of iron orees and gangue has been purified for stable isotope analysis. The isotope ratio data assure that occurrence of dynamothermal metamorphism in these areas typically involves a lengthy period of time, which results in a tendency toward isotopic homogenization specifically in O and H stable isotopes and showing the role of metamorphic waters in mineralization process. Measurement of δ34S (CDT) in first generation of pyrite is higher than another ones, so it confirms the volcanogenic origin of primary iron mineralization. δ13C data measurements in Galali carbonate country rocks show a marine origin. δ18O in magnetite and skarn forming silicates, δ18O and δ13C in limestone and skarn calcite and δ34S in sulphides are all consistent with the interaction of a magmatic-equilibrated fluid with Galali limestone, and a dominantly magmatic source for S. All these data imply skarn formation and mineralisation in a magmatic-hydrothermal system that maintained high salinity to relatively late stages resulting in the formation of the regional Na metasomatic alteration halo. Late stage hydrothermal quartz-calcite veinlets are important for gold mineralization, but the economic evaluation is required to detailed geochemical studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron" title="iron">iron</a>, <a href="https://publications.waset.org/abstracts/search?q=polygenetic" title=" polygenetic"> polygenetic</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=BabaAli" title=" BabaAli"> BabaAli</a>, <a href="https://publications.waset.org/abstracts/search?q=Galali" title=" Galali "> Galali </a> </p> <a href="https://publications.waset.org/abstracts/42430/polygenetic-iron-mineralization-in-the-baba-ali-and-galali-deposits-further-evidences-from-stable-s-o-h-isotope-data-nw-hamedan-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42430.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">301</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> High Viscous Oil–Water Flow: Experiments and CFD Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Archibong-Eso">A.

Likewise, project execution is the third phase in project lifecycle, is the phase where the work of the project must get done correctly and it’s the longest phase in the project lifecycle therefore, they must be effectively communicated, now today Communication has become the crucial element of every organization. During construction project delivery, information needs to be accurately and timely communicating among project stakeholders in order to realize the project objective. Effective communication among stakeholders during construction project delivery is one of the major factors that impact construction project delivery. Therefore, the aim of the research work is to examine the critical factors influencing effective communication among stakeholders on construction project delivery from the perspective of construction professionals (Architects, Builders, Quantity surveyors, and Civil engineers). A quantitative approach was adopted. This entailed the used of structured questionnaire to one (108) construction professionals in public and private organization within dutse metropolis. Frequency, mean, ranking and multiple linear regression using SPSS vision 25 software were used to analyses the data. The results show that Leadership, Trust, Communication tools, Communication skills, Stakeholders involvement, Cultural differences, and Communication technology were the most critical factors influencing effective communication among stakeholders on construction project delivery. The hypothesis revealed that, effective communication among stakeholders has significant effects on construction project delivery. This research work will profit the construction stakeholders in construction industry, by providing adequate knowledge regarding the factors influencing effective communication among stakeholders, so that necessary steps to be taken to improve project performance. Also, it will provide knowledge about the appropriate strategies to employ in order to improve communication among stakeholders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effetive%20communication" title="effetive communication">effetive communication</a>, <a href="https://publications.waset.org/abstracts/search?q=ineffective%20communication" title=" ineffective communication"> ineffective communication</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders"> stakeholders</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20delivery" title=" project delivery"> project delivery</a> </p> <a href="https://publications.waset.org/abstracts/183441/critical-factors-influencing-effective-communication-among-stakeholders-on-construction-project-delivery-in-jigawa-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183441.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">51</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 Effect of Some Macrofungi Extracts on Cytoplasmic Membrane of Multidrug Resistant Bacteria by Flow Cytometry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yener%20Tekeli">Yener Tekeli</a>, <a href="https://publications.waset.org/abstracts/search?q=Hayri%20Baba"> Hayri Baba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The natural active compounds found in medicinal plants are belong to various chemical structures including polyphenolic compounds, flavonoids, essential oils, and vitamins and some of these compounds have anticancer, antioxidant, and antimicrobial activity.

This experiments exhibited enhancement of these extracts to disrupt the cytoplasmic membrane of living bacterial (Listeria innocua and Escherichia coli) cells. These experiments were designed to detect uptake of PI&SYT by enhancing with a ranged concentration of herb extracts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title="antimicrobial activity">antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20cytometry" title=" flow cytometry"> flow cytometry</a>, <a href="https://publications.waset.org/abstracts/search?q=macrofungi" title=" macrofungi"> macrofungi</a>, <a href="https://publications.waset.org/abstracts/search?q=multidrug%20resistant" title=" multidrug resistant "> multidrug resistant </a> </p> <a href="https://publications.waset.org/abstracts/34026/the-effect-of-some-macrofungi-extracts-on-cytoplasmic-membrane-of-multidrug-resistant-bacteria-by-flow-cytometry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34026.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">445</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> Analysis of Technical Efficiency and Its Determinants among Cattle Fattening Enterprises in Kebbi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gona%20Ayuba">Gona Ayuba</a>, <a href="https://publications.waset.org/abstracts/search?q=Isiaka%20Mohammed"> Isiaka Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Kotom%20Mohammed%20Baba"> Kotom Mohammed Baba</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Aabubakar%20Maikasuwa"> Mohammed Aabubakar Maikasuwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study examined the technical efficiency and its determinants of cattle fattening enterprises in Kebbi state, Nigeria. Data were collected from a sample of 160 fatteners between June 2010 and June 2011 using the multistage random sampling technique. Translog stochastic frontier production function was employed for the analysis. Results of the analysis show that technical efficiency indices varied from 0.74 to 0.98%, with a mean of 0.90%, indicating that there was no wide gap between the efficiency of best technical efficient fatteners and that of the average fattener. The result also showed that fattening experience and herd size influenced the level of technical efficiency at 1% levels. It is recommended that credit agencies should ensure that credit made available to the fatteners is monitored to ensure appropriate utilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=technical%20efficiency" title="technical efficiency">technical efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=determinants" title=" determinants"> determinants</a>, <a href="https://publications.waset.org/abstracts/search?q=cattle" title=" cattle"> cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=fattening%20enterprises" title=" fattening enterprises"> fattening enterprises</a> </p> <a href="https://publications.waset.org/abstracts/48489/analysis-of-technical-efficiency-and-its-determinants-among-cattle-fattening-enterprises-in-kebbi-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48489.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">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Study of Low Loading Heavier Phase in Horizontal Oil-Water Liquid-Liquid Pipe Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aminu%20J.%20A.%20Koguna">Aminu J.

Water being one of the heavier phases tends to settle at the bottom of pipelines especially at low flow velocities and this has adverse consequences for pipeline integrity. On restart after a shutdown this could result in corrosion and issues for process equipment, thus the need to have the heavier liquid dispersed into the flowing lighter fluid. This study looked at the flow regime of low water cut and low flow velocity oil and water flow using conductive film thickness probes in a large diameter 4-inch pipe to obtain oil and water interface height and the interface structural velocity. A wide range of 0.1–1.0 m/s oil and water mixture velocities was investigated for 0.5–5% water cut.

These ethnic minorities are African –Caribbean, Indians, Pakistanis, Banghaladashi and Chinese. For policy development ethnic diversity was among the problem of developing policy in United Kingdom. The study finds that there is a danger in treating all ethnic minority businesses as homogeneous rather than heterogeneous. The diversity is due to religious beliefs, culture and race. This indicates that there is a wide range have shortfall in addressing the peculiarities of ethnic minority businesses in policy formulation. Also, there are differences between ethnic minorities in accessing finance.

We investigate the relationship between the number of women directors on the board and important board committees and financial performance measured as return on assets. Our statistical analysis supports the theoretical position of the effect diversity on financial performance. These studies enhanced the previous studies on the board of director’s gender diversity, board committees, and its impacts on firm financial performance. The study uses data from eighteen (18) Nigerian commercial banks. The study finds that banks with a higher number of females directors on board and board committees have higher Earning per share(EPS)) and Return on Assets (ROA). It also finds that some banks did not even have a single female on its corporate board. Evidence imply that decisions concerning the appointment of women to corporate boards should be on criteria and financial performance. It is recommended that banks can enhance their financial performance by having more female directors on their corporate board. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=board%20of%20directors" title="board of directors">board of directors</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20diversity" title=" gender diversity"> gender diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=board%20committees" title=" board committees"> board committees</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20performance" title=" financial performance"> financial performance</a> </p> <a href="https://publications.waset.org/abstracts/47226/board-of-directors-gender-diversity-board-committees-and-financial-performance-evidence-from-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47226.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">323</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> E-Book: An Essential Tool for Promoting Reading and Learning Amongst Students of Niger State College of Education, Minna</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulkadir%20Mustapha%20Gana">Abdulkadir Mustapha Gana</a>, <a href="https://publications.waset.org/abstracts/search?q=Musa%20Baba%20Adamu"> Musa Baba Adamu</a>, <a href="https://publications.waset.org/abstracts/search?q=Edimeh%20Augustine%20Jr"> Edimeh Augustine Jr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are growing concerns over the astronomical decline inquality of teaching and learning amongst youths especially in developing countries, and handful research have been conducted in this regard. However, results from many of these studies revealed similar findings which all pointed to the steady decline in quality of teaching and learning across the globe. One common factor attributed for this drawback was the new media due to the evolution and advancement of technology as studies have revealed. In the beginning, what was then the new media (broadcast media of radio and television) was singled out as being responsible for diverting people’s attention from reading; particularly television. At present times, it was revealed that the social media and internet connectivity were responsible for diverting the attention of many, thus distracting attentions from reading. However, it is pertinent to note that the devastating effects, social media platforms have a couple of tools that could improve reading by extension teaching and learning amongst students. Therefore, this study reviewed the literature on the advantageous aspect of social media to reading and learning; whilst laying emphasis on how youths can utilize social media to improve their reading habits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ebook" title="ebook">ebook</a>, <a href="https://publications.waset.org/abstracts/search?q=reading" title=" reading"> reading</a>, <a href="https://publications.waset.org/abstracts/search?q=learning" title=" learning"> learning</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/169707/e-book-an-essential-tool-for-promoting-reading-and-learning-amongst-students-of-niger-state-college-of-education-minna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169707.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Assessment of Digital Literacy Skills of Librarians in Tertiary Institutions Inniger State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustapha%20%20Abdulkadir%20Gana">Mustapha Abdulkadir Gana</a>, <a href="https://publications.waset.org/abstracts/search?q=Jibrin%20%20Attahiru%20Alhassan"> Jibrin Attahiru Alhassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Adamu%20%20Musa%20Baba"> Adamu Musa Baba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The exponential growth of information sources, resources and the continued Communication Technology (ICT) sophistication of libraries all over the world call for capable and ICT compliant librarians in Nigeria, this article assesses the digital literacy skills of librarians in tertiary institutions in Niger state.

Although, the present state of insecurity has become serious issue devastating the peace, unity, stability and progress of man and his physical environment particularly in developing countries. Recently, measure of security and it management in Nigeria has been a bottle-neck to the effectiveness and advancement of various sectors that include; business, education, social relations, politics and above all an economy. Several measures have been considered on mitigating environment insecurity such as surveillance, demarcation, security personnel empowerment and the likes, but still the issue remains disturbing. In this paper, we present the application of new technology that contributes to the improvement of security surveillance known as “Wireless Sensor Network (WSN)”. The system is new, smart and emerging technology that provides monitoring, detection and aggregation of information using sensor nodes and wireless network. WSN detects, monitors and stores information or activities in the deployed area such as schools, environment, business centers, public squares, industries, and outskirts and transmit to end users. This will reduce the cost of security funding and eases security surveillance depending on the nature and the requirement of the deployment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=application" title="application">application</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=insecurity" title=" insecurity"> insecurity</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title=" wireless sensor network"> wireless sensor network</a> </p> <a href="https://publications.waset.org/abstracts/44680/enhancement-of-environmental-security-by-the-application-of-wireless-sensor-network-in-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44680.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">263</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> Law Verses Tradition: Beliefs in and Practices of Witchcraft in Contemporary Ghana and the Law</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baba%20Iddrisu%20Musah">Baba Iddrisu Musah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many Ghanaians, including the rich and downtrodden, elite and unlettered, rural and urban dwellers, politicians and civil servants, in one way or the other, believe in and practice witchcraft. The existence of witches’ camp in northern Ghana, the rise of Pentecostal churches, especially in southern Ghana with the penchant to cleanse people of witchcraft, as well as media reports of witchcraft imputations assuming wider dimensions in the country, often classified as a citadel of democracy, good governance and human rights in Africa, buttress the pervasive nature of belief in and the practice of witchcraft in the country. This is in spite of the fact that tremendous efforts, especially by British colonial authorities, were made to regulate witchcraft beliefs and its associated practices. Informed by Western values and philosophy, witchcraft was considered by colonial authorities as illogical and unscientific. This paper, which is largely a review of existing literature, supplemented by archival information from the national archives of Ghana, focuses on the nature of witchcraft regulation in Ghana’s pre-colonial and colonial past, as well as immediately after Ghana obtained her independence in 1957. This article concludes by rhetorically questioning whether or not believing in and the practice of witchcraft in contemporary Ghana in general, and the existence of witches’ camps in the northern region of the country are attributed to the failure of past regulations, as well as the failure of present government policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colonial" title="colonial">colonial</a>, <a href="https://publications.waset.org/abstracts/search?q=natives" title=" natives"> natives</a>, <a href="https://publications.waset.org/abstracts/search?q=regulation" title=" regulation"> regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=witchcraft" title=" witchcraft"> witchcraft</a> </p> <a href="https://publications.waset.org/abstracts/85009/law-verses-tradition-beliefs-in-and-practices-of-witchcraft-in-contemporary-ghana-and-the-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85009.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">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> A Review on Literatures in Management and Maintenance of WAQF Properties in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huraizah%20Arshad">Huraizah Arshad</a>, <a href="https://publications.waset.org/abstracts/search?q=Maizan%20Baba"> Maizan Baba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malaysia is the country that consists of high population of Muslim community with more than 60%; as reported in year 2014. The stability of economy allowed people to contribute towards ongoing charity such as waqf and infaq. Waqf is an important component of the Islamic economic instruments since it is beneficial to help those needy in the community. Although waqf had been implemented in Malaysia for many years, there is no specific framework on how to manage and maintain the waqf properties in effective and efficient practice. Thus, a comprehensive framework related to the management and maintenance of the waqf properties is crucial to ensure that the administration of the fund is fair within the community. The objective of this article is to examine the related literatures in administration, management and maintenance of waqf for the past ten (10) years. The methodology of this article is through qualitative research based on literature on waqf administration and management; waqf planning and development and the application of maintenance concept. Data from each articles related in this field were collected and statistically analyzed using the SPSS software. A variable such as authorship patterns, number of articles published and geographical affiliation are identified in this study.

Motivated by this fact, the stochastic model predictive control method in which a performance index is minimized subject to probabilistic constraints imposed on the state variables of systems has been proposed for linear feedback control systems with random dither quantization. In other words, a method for solving optimal control problems subject to probabilistic state constraints for linear discrete-time control systems with random dither quantization has been already established. To our best knowledge, however, the feasibility of such a kind of optimal control problems has not yet been studied. Our objective in this paper is to investigate the feasibility of stochastic model predictive control problems for linear discrete-time control systems with random dither quantization. To this end, we provide the results of numerical simulations that verify the feasibility of stochastic model predictive control problems for linear discrete-time control systems with random dither quantization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=model%20predictive%20control" title="model predictive control">model predictive control</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20systems" title=" stochastic systems"> stochastic systems</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20constraints" title=" probabilistic constraints"> probabilistic constraints</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20dither%20quantization" title=" random dither quantization"> random dither quantization</a> </p> <a href="https://publications.waset.org/abstracts/78538/numerical-simulations-on-feasibility-of-stochastic-model-predictive-control-for-linear-discrete-time-systems-with-random-dither-quantization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78538.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">281</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> Radiological Assessment of Fish Samples Due to Natural Radionuclides in River Yobe, North Eastern Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20T.%20Abba">H.

Radioactivity is phenomenon that leads to production of radiations, whereas radiation is known to trigger or induce cancer. The fish were analyzed to estimate the radioactivity (activity) concentrations due to natural radionuclides (Radium 222(226Ra), Thorium 232 (232Th) and Potassium 40 (40K)). The obtained result show that the activity concentration for (226Ra), in all the fish samples collected ranges from 15.23±2.45 BqKg-1 to 67.39±2.13 BqKg-1 with an average value of 34.13±1.34 BqKg-1. That of 232Th, ranges from 42.66±0.81 BqKg-1 to 201.18±3.82 BqKg-1, and the average value stands at 96.01±3.82 BqKg-1. The activity concentration for 40K, ranges between 243.3±1.56 BqKg-1 to 618.2±2.81 BqKg-1 and the average is 413.92±1.7 BqKg-1. This study indicated that average daily intake due to natural activity from the fish is valued at 0.913 Bq/day, 2.577Bq/day and 11.088 Bq/day for 226Ra, 232Th and 40K respectively. This shows that the activity concentration values for fish, shows a promising result with most of the fish activity concentrations been within the acceptable limits. However locations (F02, F07 and F12) fish, became outliers with significant values of 112.53μSvy-1, 121.11μSvy-1 and 114.32μSvy-1 effective Dose. This could be attributed to variation in geological formations within the river as while as the feeding habits of these fish. The work shows that consumers of fish from River Yobe have no risk of radioactivity ingestion, even though no amount of radiation is assumed to be totally safe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radiation" title="radiation">radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=radio-activity" title=" radio-activity"> radio-activity</a>, <a href="https://publications.waset.org/abstracts/search?q=dose" title=" dose"> dose</a>, <a href="https://publications.waset.org/abstracts/search?q=radionuclides" title=" radionuclides"> radionuclides</a>, <a href="https://publications.waset.org/abstracts/search?q=river%20Yobe" title=" river Yobe "> river Yobe </a> </p> <a href="https://publications.waset.org/abstracts/12312/radiological-assessment-of-fish-samples-due-to-natural-radionuclides-in-river-yobe-north-eastern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12312.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">318</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> Potassium Acetate - Coconut Shell Activated Carbon for Adsorption of Benzene and Toluene: Equilibrium and Kinetic Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jibril%20Mohammed">Jibril Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Usman%20Dadum%20Hamza"> Usman Dadum Hamza</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulsalam%20Surajudeen"> Abdulsalam Surajudeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Baba%20Yahya%20Danjuma"> Baba Yahya Danjuma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considerable concerns have been raised over the presence of volatile organic compounds (VOCs) in water. In this study, coconut shell based activated carbon was produced through chemical activation with potassium acetate (PAAC) for adsorption of benzene and toluene. The porous carbons were characterized using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), proximate analysis, and ultimate analysis and nitrogen adsorption tests. Adsorption of benzene and toluene on the porous carbons were conducted at varying concentrations (50-250 mg/l). The high BET surface area of 622 m2/g and highly heteroporous adsorbent prepared gave good removal efficiencies of 79 and 82% for benzene and toluene respectively, with 32% yield. Equilibrium data were fitted to Langmuir, Freundlich and Temkin isotherms with all the models having R2 > 0.94. The equilibrium data were best represented by the Langmuir isotherm, with maximum adsorption capacity of 192 mg/g and 227 mg/g for benzene and toluene respectively. The Webber and Chakkravorti equilibrium parameter (RL) values are between 0 and 1 confirming the favourability of the Langmuir model. The adsorption kinetics was found to follow the pseudo-second-order kinetic model. The PAAC produced can be used effectively to salvage environmental pollution problems posed by VOCs through a sustainable process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=equilibrium%20and%20kinetics%20studies" title=" equilibrium and kinetics studies"> equilibrium and kinetics studies</a>, <a href="https://publications.waset.org/abstracts/search?q=potassium%20acetate" title=" potassium acetate"> potassium acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title=" water treatment "> water treatment </a> </p> <a href="https://publications.waset.org/abstracts/47700/potassium-acetate-coconut-shell-activated-carbon-for-adsorption-of-benzene-and-toluene-equilibrium-and-kinetic-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47700.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">22</span> Geoelectrical Investigation Around Bomo Area, Kaduna State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20S.%20Jatau">B.

Vertical Electrical Sounding (VES) using Schlumberger array was carried out at fifteen (15) VES stations. ABEM terrameter (SAS 300) was used for the data acquisition. The field data obtained have been analyzed using computer software (IPI2win) which gives an automatic interpretation of the apparent resistivity. The VES results revealed heterogeneous nature of the subsurface geological sequence. The geologic sequence beneath the study area is composed of hard pan top soil (clayey and sandy-lateritic), weathered layer, partly weathered or fractured basement and fresh basement. The resistivity value for the topsoil layer varies from 40Ωm to 450Ωm with thickness ranging from 1.25 to 7.5 m. The weathered basement has resistivity values ranging from 50Ωm to 593Ωm and thickness between 1.37 and 20.1 m. The fractured basement has resistivity values ranging from 218Ωm to 520Ωm and thickness of between 12.9 and 26.3 m. The fresh basement (bedrock) has resistivity values ranging from 1215Ωm to 2150Ωm with infinite depth. However, the depth of the earth’s surface to the bedrock surface varies between 2.63 and 34.99 m. The study further stressed the importance of the findings in civil engineering structures and groundwater prospecting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20resistivity" title="electrical resistivity">electrical resistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=CERT%20%28CT%29" title=" CERT (CT)"> CERT (CT)</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20electrical%20sounding%20%28VES%29" title=" vertical electrical sounding (VES)"> vertical electrical sounding (VES)</a>, <a href="https://publications.waset.org/abstracts/search?q=top%20soil%20%28TP%29" title=" top soil (TP)"> top soil (TP)</a>, <a href="https://publications.waset.org/abstracts/search?q=weathered%20basement%20%28WB%29" title=" weathered basement (WB)"> weathered basement (WB)</a>, <a href="https://publications.waset.org/abstracts/search?q=partly%20weathered%20basement%20%28PWB%29" title=" partly weathered basement (PWB)"> partly weathered basement (PWB)</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20basement%20%28FB%29" title=" fresh basement (FB)"> fresh basement (FB)</a> </p> <a href="https://publications.waset.org/abstracts/3919/geoelectrical-investigation-around-bomo-area-kaduna-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3919.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">327</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> Dry Season Rice Production along Hadejia Valley Irrigation Scheme in Auyo Local Government Area in Jigawa State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saifullahi%20Umar">Saifullahi Umar</a>, <a href="https://publications.waset.org/abstracts/search?q=Baba%20Mamman%20Yarima"> Baba Mamman Yarima</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Bello%20Usman"> Mohammed Bello Usman</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Mohammed"> Hassan Mohammed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted along with the Hadejia valley project irrigation under the Hadejia-Jama’are River Basin Development Authority (HRBDA) in Jigawa State. The multi-stage sampling procedure was used to select 72 rice farmers operating along with the Hadejia Valley Irrigation Project. Data for the study were collected using a structured questionnaire. The analytical tools employed for the study were descriptive statistics and Farm budget technique. The result shows that 55% of the farmers were between 31-40 years of age, 66.01% were male, and the result also revealed that the total cost of cultivation of an acre of land for rice production during the dry season was N73,900 with input cost accounting for 63.59% of the total cost of production. The gross return was N332,500, with a net return of N258,600 per acre. The estimated benefit-cost ratio of 3.449 indicates the strong performance of the dry season rice production. The leading constraints to dry season rice production were low access to quality extension services, low access to finance, poor quality fertilizers, and poor prices. The study, therefore, concludes that dry season rice production is a profitable enterprise in the study area hence, to productivity the farmers should be linked to effective extension service delivery institutions, expanding their access to productive sources of finances, the government should strengthen fertilizer quality control measures and comprehensive market linkages for the farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Auyo" title="Auyo">Auyo</a>, <a href="https://publications.waset.org/abstracts/search?q=dry%20season" title=" dry season"> dry season</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadejia%20Valley" title=" Hadejia Valley"> Hadejia Valley</a>, <a href="https://publications.waset.org/abstracts/search?q=rice" title=" rice"> rice</a> </p> <a href="https://publications.waset.org/abstracts/118617/dry-season-rice-production-along-hadejia-valley-irrigation-scheme-in-auyo-local-government-area-in-jigawa-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118617.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">164</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> A Study of High Viscosity Oil-Gas Slug Flow Using Gamma Densitometer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Baba">Y.

Yeung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Experimental study of high viscosity oil-gas flows in horizontal pipelines published in literature has indicated that hydrodynamic slug flow is the dominant flow pattern observed. Investigations have shown that hydrodynamic slugging brings about high instabilities in pressure that can damage production facilities thereby making it inherent to study high viscous slug flow regime so as to improve the understanding of its flow dynamics. Most slug flow models used in the petroleum industry for the design of pipelines together with their closure relationships were formulated based on observations of low viscosity liquid-gas flows. New experimental investigations and data are therefore required to validate these models. In cases where these models underperform, improving upon or building new predictive models and correlations will also depend on the new experimental dataset and further understanding of the flow dynamics in high viscous oil-gas flows. In this study conducted at the Flow laboratory, Oil and Gas Engineering Centre of Cranfield University, slug flow variables such as pressure gradient, mean liquid holdup, frequency and slug length for oil viscosity ranging from 1..0 – 5.5 Pa.s are experimentally investigated and analysed. The study was carried out in a 0.076m ID pipe, two fast sampling gamma densitometer and pressure transducers (differential and point) were used to obtain experimental measurements. Comparison of the measured slug flow parameters to the existing slug flow prediction models available in the literature showed disagreement with high viscosity experimental data thus highlighting the importance of building new predictive models and correlations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gamma%20densitometer" title="gamma densitometer">gamma densitometer</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20liquid%20holdup" title=" mean liquid holdup"> mean liquid holdup</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20gradient" title=" pressure gradient"> pressure gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=slug%20frequency%20and%20slug%20length" title=" slug frequency and slug length"> slug frequency and slug length</a> </p> <a href="https://publications.waset.org/abstracts/33621/a-study-of-high-viscosity-oil-gas-slug-flow-using-gamma-densitometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33621.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">329</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> Improved Water Productivity by Deficit Irrigation: Implications for Water Saving in Orange, Olive and Vineyard Orchards in Arid Conditions of Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Nagaz">K.

Four irrigation treatments were compared: full irrigation (FI), which was irrigated at 100% of ETc for the whole season; two deficit irrigation (DI) strategies -DI75 and DI50- which received, respectively, 25 and 50% less water than FI; and traditional farming management (FM) - with water input much less than actually needed. The traditional farming (FM) applied 11, 18, 30 and 33% less water than the FI treatment, respectively, in orange, grapevine and table and oil olive orchards, indicating that the farmers practices represent a form of unintended deficit irrigation. Yield was reduced when deficit irrigation was applied and there were significant differences between DI75, DI50 and FM treatments. Significant differences were not observed between DI50 and FM treatments even though numerically smaller yield was observed in the former (DI50) as compared to the latter (FM). The irrigation water productivity (IWP) was significantly affected by irrigation treatments. The smallest IWP was recorded under the FI treatment, while the largest IWP was obtained under the deficit irrigation treatment (DI50). The DI50 and FM treatments reduced the economic return compared to the full treatment (FI), while the DI75 treatment resulted in a better economic return in respect to DI50 and FM. Full irrigation (FI) could be recommended for olive, orange and grapevine irrigation under the arid climate of Tunisia. Nevertheless, the treatment DI75 can be applied as a strategy under water scarcity conditions in commercial olive, orange and grapevine orchards allowing water savings up to 25% but with some reduction in yield and net return. The results would be helpful in adopting deficit irrigation in ways that enhance net financial returns. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20productivity" title="water productivity">water productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=deficit%20irrigation" title=" deficit irrigation"> deficit irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=drip%20irrigation" title=" drip irrigation"> drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=orchards" title=" orchards"> orchards</a> </p> <a href="https://publications.waset.org/abstracts/68095/improved-water-productivity-by-deficit-irrigation-implications-for-water-saving-in-orange-olive-and-vineyard-orchards-in-arid-conditions-of-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68095.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">223</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> Seismic Performance of Steel Shear Wall Using Experimental and Numerical Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wahab%20Abdul%20Ghafar">Wahab Abdul Ghafar</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Zhong"> Tao Zhong</a>, <a href="https://publications.waset.org/abstracts/search?q=Baba%20Kalan%20Enamullah"> Baba Kalan Enamullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steel plate shear walls (SPSWs) are a robust lateral load resistance structure because of their high flexibility and efficient energy dissipation when subjected to seismic loads. This research investigates the seismic Performance of an innovative infill web strip (IWS-SPSW) and a typical unstiffened steel plate shear wall (USPSW). As a result, two 1:3 scale specimens of an IWS-SPSW and USPSW with a single story and a single bay were built and subjected to a cyclic lateral loading methodology. In the prototype, the beam-to-column connections were accomplished with the assistance of semi-rigid end-plate connectors. IWS-SPSW demonstrated exceptional ductility and shear load-bearing capacity during the testing process, with no cracks or other damage occurring. In addition, the IWS-SPSW could effectively dissipate energy without causing a significant amount of beam-column connection distortion. The shear load-bearing capacity of the USPSW was exceptional. However, it exhibited low ductility, severe infill plate corner ripping, and huge infill web plate cracks. The FE models were created and then confirmed using the experimental data. It has been demonstrated that the infill web strips of an SPSW system can affect the system's high Performance and total energy dissipation. In addition, a parametric analysis was carried out to evaluate the material qualities of the IWS, which can considerably improve the system's seismic performances. These properties include the steel's strength as well as its thickness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel%20shear%20walls" title="steel shear walls">steel shear walls</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20performance" title=" seismic performance"> seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=failure%20mode" title=" failure mode"> failure mode</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis%20response" title=" hysteresis response"> hysteresis response</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20finite%20element%20analysis" title=" nonlinear finite element analysis"> nonlinear finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=parametric%20study." title=" parametric study."> parametric study.</a> </p> <a href="https://publications.waset.org/abstracts/160502/seismic-performance-of-steel-shear-wall-using-experimental-and-numerical-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160502.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">17</span> Prioritization Assessment of Housing Development Risk Factors: A Fuzzy Hierarchical Process-Based Approach </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Garba%20Baba">Yusuf Garba Baba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The construction industry and housing subsector are fraught with risks that have the potential of negatively impacting on the achievement of project objectives. The success or otherwise of most construction projects depends to large extent on how well these risks have been managed. The recent paradigm shift by the subsector to use of formal risk management approach in contrast to hitherto developed rules of thumb means that risks must not only be identified but also properly assessed and responded to in a systematic manner. The study focused on identifying risks associated with housing development projects and prioritisation assessment of the identified risks in order to provide basis for informed decision. The study used a three-step identification framework: review of literature for similar projects, expert consultation and questionnaire based survey to identify potential risk factors. Delphi survey method was employed in carrying out the relative prioritization assessment of the risks factors using computer-based Analytical Hierarchical Process (AHP) software. The results show that 19 out of the 50 risks significantly impact on housing development projects. The study concludes that although significant numbers of risk factors have been identified as having relevance and impacting to housing construction projects, economic risk group and, in particular, ‘changes in demand for houses’ is prioritised by most developers as posing a threat to the achievement of their housing development objectives. Unless these risks are carefully managed, their effects will continue to impede success in these projects. The study recommends the adoption and use of the combination of multi-technique identification framework and AHP prioritization assessment methodology as a suitable model for the assessment of risks in housing development projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title="risk management">risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20identification" title=" risk identification"> risk identification</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20analysis" title=" risk analysis"> risk analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=analytic%20hierarchical%20process" title=" analytic hierarchical process"> analytic hierarchical process</a> </p> <a href="https://publications.waset.org/abstracts/108045/prioritization-assessment-of-housing-development-risk-factors-a-fuzzy-hierarchical-process-based-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108045.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">118</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> Hydrometallurgical Processing of a Nigerian Chalcopyrite Ore</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alafara%20A.%20Baba">Alafara A.

At a particular set of experimental parameter with respect to acid concentration, reaction temperature and particle size, the leaching investigation showed that the ore dissolution increases with increasing acid concentration, temperature and decreasing particle diameter at a moderate stirring. The kinetics data has been analyzed and was found to follow diffusion control mechanism. At optimal conditions, the extent of ore dissolution reached 94.3%. The recovery of the total copper from the hydrochloric acid-leached chalcopyrite ore was undertaken by solvent extraction and precipitation techniques, prior to the beneficiation of the purified solution as copper oxide. The purification of the leach liquor was firstly done by precipitation of total iron and manganese using Ca(OH)2 and H2O2 as oxidizer at pH 3.5 and 4.25, respectively. An extraction efficiency of 97.3% total copper was obtained by 0.2 mol/L Dithizone in kerosene at 25±2ºC within 40 minutes, from which ≈98% Cu from loaded organic phase was successfully stripped by 0.1 mol/L HCl solution. The beneficiation of the recovered pure copper solution was carried out by crystallization through alkali addition followed by calcination at 600ºC to obtain high grade copper oxide (Tenorite, CuO: 05-0661). Finally, a simple hydrometallurgical scheme for the operational extraction procedure amenable for industrial utilization and economic sustainability was provided. <p
