This work was carried out to study the distribution and densities of mosquitoes adults and larvae in a total of five selected stations in El Obied Town. A cross-sectional survey of Anopheline mosquito larval habitats was conducted. The survey was conducted during the dry season (January 2013). Larvae were collected by using the standard dipping technique, while adult stages were collected by rearing larvae in cage, because the density of adults Anopheles mosquito per room was zero by using spray sheet method by using Permethrin pesticide 25%E.C, during the study period. The results revealed that (2347) Anopheline mosquito larvae were found and collected from only one station. All of which (2347) larvae (100%) were classified as probably Anopheles Squamosus. The study also showed that, a number of 81 adults (100%) Anopheline mosquito were classified as probably Anopheles Squamosus. Anopheles Squamosus were found only in the shallow pond water habitat in Alrahma west area of El Obied, the mean Anopheline density in the study area for larvae was 0.313 per dip while the mean density of adult was 0 per room. The high mosquito larval density in Alrahma west area indicated that, this part of El Obied Town is at risk of mosquito-borne diseases including malaria. This study recommended to apply the control program against mosquito at this part of the Town. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anopheles" title="anopheles">anopheles</a>, <a href="https://publications.waset.org/abstracts/search?q=squamosus" title=" squamosus"> squamosus</a>, <a href="https://publications.waset.org/abstracts/search?q=Alrahma" title=" Alrahma"> Alrahma</a>, <a href="https://publications.waset.org/abstracts/search?q=distribution" title=" distribution"> distribution</a> </p> <a href="https://publications.waset.org/abstracts/76461/distribution-and-densities-of-anopheles-mosquito-in-el-obied-town-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76461.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">285</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> High Performance Methyl Orange Capture on Magnetic Nanoporous MCM-41 Prepared by Incipient Wetness Impregnation Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talib%20M.%20Albayati">Talib M.

This research aimed to uncover the elements influencing the effectiveness of management creativity by employing the Theory of Planned Behavior. The study's findings indicate that two significant predictors of management creativity effectiveness are one's attitude towards it and the subjective norms within the organization. Such results are rather important for the organizations and their leaders who would want to increase management creativity. The attitudes of subordinates towards management creativity should be positive if managers wish to cultivate management creativity among their employees, and the organizational culture must also be one that enhances and supports creative thinking. They should also make available all the requisite resources and support required for the implementation of their creative ideas and let employees participate in the decision-making processes in order to increase their sense of control over their creative activities. This research contributes to the literature on managerial creativity by presenting evidence about the effectiveness of managerial creativity and the strategies aimed at increasing the level of creativity in organizations through empirical insights. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=management%20creativity" title="management creativity">management creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes" title=" attitudes"> attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20norms" title=" subjective norms"> subjective norms</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20behavioral%20control" title=" perceived behavioral control"> perceived behavioral control</a> </p> <a href="https://publications.waset.org/abstracts/193897/factors-affecting-the-effectiveness-of-management-creativity-using-theory-planned-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193897.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">9</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Investigation the Effect of Quenching Media on Abrasive Wear in Grade Medium Carbon Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abbas%20S.%20Alwan">Abbas S.

This technique is found promising to improve the quality of agriculture components working with the soil in dry condition. Abrasive wear resistance is very important in many applications and in most cases it is directly correlated with the hardness of materials surface. Responded of heat treatments were carried out in various media (Still air, Cottonseed oil, and Brine water 10 %) and follow by low-temperature tempering (250°C) was applied on steel type (AISI 1030). After heat treatment was applied wear with soil texture by using tillage process to determine the (actual wear rate) of the specimens depending on weight loss method. It was found; the wear resistance Increases with increase hardness with varying quenching media as follows; 30 HRC, 45 HRC, 52 HRC, and 60 HRC for nontreated (as received) cooling media as still air, cottonseed oil, and Brine water 10 %, respectively. Martensitic structure with retained austenite can be obtained depending on the quenching medium. Wear was presented on the worn surfaces of the steels which were used in this work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microstructures" title="microstructures">microstructures</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a>, <a href="https://publications.waset.org/abstracts/search?q=abrasive%20wear" title=" abrasive wear"> abrasive wear</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20texture" title=" soil texture"> soil texture</a> </p> <a href="https://publications.waset.org/abstracts/19571/investigation-the-effect-of-quenching-media-on-abrasive-wear-in-grade-medium-carbon-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19571.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">388</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> The Impact of Quality Cost on Revenue Sharing in Supply Chain Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fayza%20M.%20Obied-Allah">Fayza M.

In the light of these challenges, modern ideas must contribute to counter these challenges and exploit opportunities. Perhaps this paper will be one of these contributions. This paper discusses the impact of the quality cost on revenue sharing as a most important incentive to configure business networks. No doubt that the costs directly affect the size of income generated by a business network, so this paper investigates the impact of quality costs on business networks revenue, and their impact on the decision to participate the revenue among the companies in the supply chain. This paper develops the quality cost approach to align with the modern era, the developed model includes five categories besides the well-known four categories (namely prevention costs, appraisal costs, internal failure costs, and external failure costs), a new category has been developed in this research as a new vision of the relationship between quality costs and innovations of industry. This new category is Recycle Cost. This paper is organized into six sections, Section I shows quality costs overview in the supply chain. Section II discusses revenue sharing between the parties in supply chain. Section III investigates the impact of quality costs in revenue sharing decision between partners in supply chain. The fourth section includes survey study and presents statistical results. Section V discusses the results and shows future opportunities for research. Finally, Section VI summarizes the theoretical and practical results of this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20cost" title="quality cost">quality cost</a>, <a href="https://publications.waset.org/abstracts/search?q=recycle%20cost" title=" recycle cost"> recycle cost</a>, <a href="https://publications.waset.org/abstracts/search?q=revenue%20sharing" title=" revenue sharing"> revenue sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title=" supply chain management"> supply chain management</a> </p> <a href="https://publications.waset.org/abstracts/27761/the-impact-of-quality-cost-on-revenue-sharing-in-supply-chain-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27761.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">5</span> Effect of Nitriding and Shot Peening on Corrosion Behavior and Surface Properties of Austenite Stainless Steel 316L</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khiaira%20S.%20Hassan">Khiaira S.

Chemical surface heat treatment by liquid nitriding process was carried out at 500 °C for 1 h and followed by shot peening with using ball steel diameter of 1.25 mm in different exposure time of 10 and 20 min. Electrochemical corrosion test was applied in sea water (3.5% NaCl solution) by using potentostat instrument. The results showed that the nitride layer consists of a compound layer (white layer) and diffusion zone immediately below the alloy layer. It has been found that the mechanical treatment (shot peening) has led to the formation of compressive residual stresses in layer surface that increased the hardness of stainless steel surface. All surface treatment (nitriding and shot peening) processes have led to the formation of carbide of CrN in hard surface layer. It was shown that both processes caused an increase in surface hardness and roughness which increases with shot peening time. Also, the corrosion results showed that the liquid nitriding and shot peening processes increase the corrosion rate to values more than that of not treated stainless steel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stainless%20steel%20316L" title="stainless steel 316L">stainless steel 316L</a>, <a href="https://publications.waset.org/abstracts/search?q=shot%20peening" title=" shot peening"> shot peening</a>, <a href="https://publications.waset.org/abstracts/search?q=nitriding" title=" nitriding"> nitriding</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=hardness" title=" hardness"> hardness</a> </p> <a href="https://publications.waset.org/abstracts/68488/effect-of-nitriding-and-shot-peening-on-corrosion-behavior-and-surface-properties-of-austenite-stainless-steel-316l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68488.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">468</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Studying the Structural Behaviour of RC Beams with Circular Openings of Different Sizes and Locations Using FE Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Shubbar">Ali Shubbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasanain%20Alwan"> Hasanain Alwan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ee%20Yu%20Phur"> Ee Yu Phur</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20McLoughlin"> John McLoughlin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ameer%20Al-khaykan"> Ameer Al-khaykan </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to investigate the structural behaviour of RC beams with circular openings of different sizes and locations modelled using ABAQUS FEM software. Seven RC beams with the dimensions of 1200 mm×150 mm×150 mm were tested under three-point loading. Group A consists of three RC beams incorporating circular openings with diameters of 40 mm, 55 mm and 65 mm in the shear zone. However, Group B consists of three RC beams incorporating circular openings with diameters of 40 mm, 55 mm and 65 mm in the flexural zone. The final RC beam did not have any openings, to provide a control beam for comparison. The results show that increasing the diameter of the openings increases the maximum deflection and the ultimate failure load decreases relative to the control beam. In the shear zone, the presence of the openings caused an increase in the maximum deflection ranging between 4% and 22% and a decrease in the ultimate failure load of between 26% and 36% compared to the control beam. However, the presence of the openings in the flexural zone caused an increase in the maximum deflection of between 1.5% and 19.7% and a decrease in the ultimate failure load of between 6% and 13% relative to the control beam. In this study, the optimum location for placing circular openings was found to be in the flexural zone of the beam with a diameter of less than 30% of the depth of the beam.<o:p></o:p></span> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultimate%20failure%20load" title="ultimate failure load">ultimate failure load</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20deflection" title=" maximum deflection"> maximum deflection</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20zone%20and%20flexural%20zone" title=" shear zone and flexural zone"> shear zone and flexural zone</a> </p> <a href="https://publications.waset.org/abstracts/76164/studying-the-structural-behaviour-of-rc-beams-with-circular-openings-of-different-sizes-and-locations-using-fe-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76164.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">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> The Level of Administrative Creativity and Its Obstacles From the Point of View of Workers in Youth Centers in Jordan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Basheer%20Ahmad%20Al-Alwan">Basheer Ahmad Al-Alwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to assess the extent of administrative creativity and identify its barriers from the perspective of employees working in youth centers in Jordan. The sample comprised 156 individuals employed in youth centers within the Hashemite Kingdom of Jordan. Data collection involved the utilization of two measures: the administrative creativity scale and the obstacles to administrative work scale. Correlation and stepwise multiple regression analyses were conducted. The findings revealed a high level of administrative creativity, as indicated by a mean score of 3.82 and a standard deviation of 0.51. Furthermore, statistically significant gender-based differences in administrative creativity were observed, favoring males, with a mean score of 3.32 for males compared to 2.91 for females. The results also demonstrated statistically significant differences in the level of administrative creativity based on experience, with the highest mean score observed for individuals with 5 to less than 10 years of experience. Regarding the obstacles to administrative creativity, the findings revealed an average level, with a mean score of 2.86 and a standard deviation of 0.791. Based on these results, the study recommends the promotion of a culture of creativity among employees and the provision of a broader scope of authority to foster an environment conducive to administrative creativity. Additionally, it suggests offering training courses encompassing the annual plan for these centers and minimizing obstacles that hinder the creative process among employees in Jordanian youth centers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=administrative%20creativity" title="administrative creativity">administrative creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=obstacles" title=" obstacles"> obstacles</a>, <a href="https://publications.waset.org/abstracts/search?q=workers%20in%20youth%20centers" title=" workers in youth centers"> workers in youth centers</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan" title=" Jordan"> Jordan</a> </p> <a href="https://publications.waset.org/abstracts/174224/the-level-of-administrative-creativity-and-its-obstacles-from-the-point-of-view-of-workers-in-youth-centers-in-jordan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174224.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">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Determination of Lithology, Porosity and Water Saturation for Mishrif Carbonate Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20S.%20Kadhim">F.

The accurate calculations of porosity in carbonate reservoirs are the most challenging aspects of well log analysis. Many equations have been developed over the years based on known physical principles or on empirically derived relationships, which are used to calculate porosity, estimate lithology and water saturation; however these parameters are calculated from well logs by using modern technique in a current study. Nasiriya (NS) oilfield is one of giant oilfields in the Middle East, and the formation under study is the Mishrif carbonate formation which is the shallowest hydrocarbon bearing zone in the NS oilfield. Neurolog software (V5, 2008) was used to digitize the scanned copies of the available logs. Environmental corrections had been made as per Schlumberger charts 2005, which supplied in the Interactive Petrophysics software (IP, V3.5, 2008). Three saturation models have been used to calculate water saturation of carbonate formations, which are simple Archie equation, Dual water model, and Indonesia model. Results indicate that the Mishrif formation consists mainly of limestone, some dolomite and shale. The porosity interpretation shows that the logging tools have a good quality after making the environmental corrections. The average formation water saturation for Mishrif formation is around 0.4-0.6.This study is provided accurate behavior of petrophysical properties with depth for this formation by using modern software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithology" title="lithology">lithology</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity" title=" porosity"> porosity</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20saturation" title=" water saturation"> water saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=carbonate%20formation" title=" carbonate formation"> carbonate formation</a>, <a href="https://publications.waset.org/abstracts/search?q=mishrif%20formation" title=" mishrif formation"> mishrif formation</a> </p> <a href="https://publications.waset.org/abstracts/27926/determination-of-lithology-porosity-and-water-saturation-for-mishrif-carbonate-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27926.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">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Reasons for the Slow Uptake of Embodied Carbon Estimation in the Sri Lankan Building Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amalka%20Nawarathna">Amalka Nawarathna</a>, <a href="https://publications.waset.org/abstracts/search?q=Nirodha%20Fernando"> Nirodha Fernando</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaid%20Alwan"> Zaid Alwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global carbon reduction is not merely a responsibility of environmentally advanced developed countries, but also a responsibility of developing countries regardless of their less impact on global carbon emissions. In recognition of that, Sri Lanka as a developing country has initiated promoting green building construction as one reduction strategy. However, notwithstanding the increasing attention on Embodied Carbon (EC) reduction in the global building sector, they still mostly focus on Operational Carbon (OC) reduction (through improving operational energy). An adequate attention has not yet been given on EC estimation and reduction. Therefore, this study aims to identify the reasons for the slow uptake of EC estimation in the Sri Lankan building sector. To achieve this aim, 16 numbers of global barriers to estimate EC were identified through existing literature. They were then subjected to a pilot survey to identify the significant reasons for the slow uptake of EC estimation in the Sri Lankan building sector. A questionnaire with a three-point Likert scale was used to this end. The collected data were analysed using descriptive statistics. The findings revealed that 11 out of 16 challenges/ barriers are highly relevant as reasons for the slow uptake in estimating EC in buildings in Sri Lanka while the other five challenges/ barriers remain as moderately relevant reasons. Further, the findings revealed that there are no low relevant reasons. Eventually, the paper concluded that all the known reasons are significant to the Sri Lankan building sector and it is necessary to address them in order to upturn the attention on EC reduction. <p
