We examined the yield, the yield production per 1kg NPK fertilizer and the water and nutrient utilization of hybrid PR37N01 and PR37M81 in 2013. We found that PR37N01 produced the most yield at the level of N120+P (17,476kg ha-1) while PR37M81 reached the highest yield at level N150+PK (16,754kg ha-1). Studies related to yield production per 1kg NPK indicated that the best results were achieved at level N30+PK compared to the control treatment. Yield production per 1kg NPK was17.6kg kg-1 by P37N01 and 44.2kg kg-1 by PR37M81. By comparing the water utilization of hybrids we found that the worst water utilization results were reached in the control treatment (PR37N01: 26.2kg mm-1, PR37M81: 19.5kg mm-1). The best water utilization values were produced at level N120+PK in the case of hybrid PR37N01 (32.1kg mm-1) and at N150+PK in the case of hybrid PR37M81 (30.8kg mm-1). We established the values of the nutrient reaction and the fertilizer optimum of hybrids. We discovered a strong relationship between the amount of fertilizer applied and the yield produced (r2= 0.8228–0.9515). The best nutrient response was induced by hybrid PR37N01, while the weakest results were reached by hybrid PR37M81. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid" title="hybrid">hybrid</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient" title=" nutrient"> nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20utilization" title=" water utilization"> water utilization</a> </p> <a href="https://publications.waset.org/abstracts/3689/examination-of-the-water-and-nutrient-utilization-of-maize-hybrids-on-chernozem-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3689.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">413</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">10245</span> Environmental Impacts and Ecological Utilization of Water Hyacinth (Eichhornia crassipes) in the Niger Delta Fresh Ecosystem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seiyaboh%20E.%20I.">Seiyaboh E.

However, it is considered a dangerous pest today because when not controlled, water hyacinth will cover rivers, lakes and ponds entirely; this dramatically impacts water flow, blocks sunlight from reaching native aquatic plants, and starves the water of oxygen, often killing fish and other aquatic organisms. In the Niger Delta region, water hyacinth is considered a nuisance because of its very obvious devastating environmental impacts in the region. However, water hyacinth (Eichhornia crassipes) constitutes a very important part of an aquatic ecosystem. It possesses specialized growth habits, physiological characteristics and reproductive strategies that allow for rapid growth and spread in freshwater environments and this explains its very rapid spread in the Niger Delta freshwater ecosystem. This paper therefore focuses on the environmental consequences of the proliferation of water hyacinth (Eichhornia crassipes) in the Niger Delta freshwater ecosystem, extent of impact, and options available for its ecological utilization which will help mitigate proliferation, restore effective freshwater ecosystem utilization and balance. It concludes by recommending sustainable practices outlining the beneficial uses of water hyacinth (Eichhornia crassipes) rather than control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title="environmental impacts">environmental impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20utilization" title=" ecological utilization"> ecological utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=Niger%20Delta" title=" Niger Delta"> Niger Delta</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20hyacinth" title=" water hyacinth"> water hyacinth</a>, <a href="https://publications.waset.org/abstracts/search?q=Eichhornia%20crassipes" title=" Eichhornia crassipes"> Eichhornia crassipes</a> </p> <a href="https://publications.waset.org/abstracts/24966/environmental-impacts-and-ecological-utilization-of-water-hyacinth-eichhornia-crassipes-in-the-niger-delta-fresh-ecosystem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24966.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">273</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">10244</span> Research on Steam Injection Technology of Extended Range Engine Cylinder for Waste Heat Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhiyuan%20Jia">Zhiyuan Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuxiu%20Sun"> Xiuxiu Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Chen"> Yong Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Liu%20Hai"> Liu Hai</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuangqing%20Li"> Shuangqing Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The engine cooling water and exhaust gas contain a large amount of available energy. In order to improve energy efficiency, a steam injection technology based on waste heat recovery is proposed. The models of cooling water waste heat utilization, exhaust gas waste heat utilization, and exhaust gas-cooling water waste heat utilization were constructed, and the effects of the three modes on the performance of steam injection were analyzed, and then the feasibility of in-cylinder water injection steam technology based on waste heat recovery was verified. The research results show that when the injection water flow rate is 0.10 kg/s and the temperature is 298 K, at a cooling water temperature of 363 K, the maximum temperature of the injection water heated by the cooling water can reach 314.5 K; at an exhaust gas temperature of 973 K and an exhaust gas flow rate of 0.12 kg/s, the maximum temperature of the injection water heated by the exhaust gas can reach 430 K; Under the condition of cooling water temperature of 363 K, exhaust gas temperature of 973 K and exhaust gas flow rate of 0.12 kg/s, after cooling water and exhaust gas heating, the maximum temperature of the injection water can reach 463 K. When the engine is 1200 rpm, the water injection volume is 30 mg, and the water injection time is 36°CA, the engine power increases by 2% and the fuel consumption is reduced by 2.6%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooling%20water" title="cooling water">cooling water</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20gas" title=" exhaust gas"> exhaust gas</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20range%20engine" title=" extended range engine"> extended range engine</a>, <a href="https://publications.waset.org/abstracts/search?q=steam%20injection" title=" steam injection"> steam injection</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20heat%20recovery" title=" waste heat recovery"> waste heat recovery</a> </p> <a href="https://publications.waset.org/abstracts/128975/research-on-steam-injection-technology-of-extended-range-engine-cylinder-for-waste-heat-recovery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128975.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">184</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">10243</span> A Review on Potential Utilization of Water Hyacinth (Eichhornia crassipes) as Livestock Feed with Particular Emphasis to Developing Countries in Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shigdaf%20Mekuriaw">Shigdaf Mekuriaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Firew%20Tegegne"> Firew Tegegne</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Tsunekawa"> A.

Water Hyacinth is one of the most noxious plant invaders of rivers and lakes. Such weeds cause environmental disaster and interfere with economic and recreational activities such as water transportation and fishing. Economic impacts of the weed in seven African countries have been estimated at between 20-50 million US$ every year. It would, therefore, be prudent to suggest utilization as a complementary control method. The majority of people in developing countries are dependent on traditional and inefficient crop-livestock production system that constrains their ability to enhance economic productivity and quality of life. Livestock in developing countries faces shortage of feed, especially during the long dry seasons. Existing literature shows the use of water hyacinth as livestock and fish feed. The chemical composition of water hyacinth varies considerably. Due to its relatively high crude protein (CP) content (5.8-20.0%), water hyacinth can be considered as a potential protein supplement for livestock which commonly feed cereal crop residues whose contribution as source of feed is increasing in Africa. Though the effects of anti-nutritional factors (ANFs) present in water hyacinth is not investigated, their concentrations are not above threshold hinder its utilization as livestock feed. In conclusion, water hyacinth could provide large quantities of nutritious feed for animals. Like other feeds, water hyacinth may not be offered as a sole feed and based on existing literature its optimum inclusion level reaches 50%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Africa" title="Africa">Africa</a>, <a href="https://publications.waset.org/abstracts/search?q=livestock%20feed" title=" livestock feed"> livestock feed</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20bodies" title=" water bodies"> water bodies</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20hyacinth%20and%20weed%20control%20method" title=" water hyacinth and weed control method"> water hyacinth and weed control method</a> </p> <a href="https://publications.waset.org/abstracts/43297/a-review-on-potential-utilization-of-water-hyacinth-eichhornia-crassipes-as-livestock-feed-with-particular-emphasis-to-developing-countries-in-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43297.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">386</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">10242</span> Consequential Effects of Coal Utilization on Urban Water Supply Sources – a Study of Ajali River in Enugu State Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enebe%20Christian%20Chukwudi">Enebe Christian Chukwudi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water bodies around the world notably underground water, ground water, rivers, streams, and seas, face degradation of their water quality as a result of activities associated with coal utilization including coal mining, coal processing, coal burning, waste storage and thermal pollution from coal plants which tend to contaminate these water bodies. This contamination results from heavy metals, presence of sulphate and iron, dissolved solids, mercury and other toxins contained in coal ash, sludge, and coal waste. These wastes sometimes find their way to sources of urban water supply and contaminate them. A major problem encountered in the supply of potable water to Enugu municipality is the contamination of Ajali River, the source of water supply to Enugu municipal by coal waste. Hydro geochemical analysis of Ajali water samples indicate high sulphate and iron content, high total dissolved solids(TDS), low pH (acidity values) and significant hardness in addition to presence of heavy metals, mercury, and other toxins. This is indicative of the following remedial measures: I. Proper disposal of mine wastes at designated disposal sites that are suitably prepared. II. Proper water treatment and III. Reduction of coal related contaminants taking advantage of clean coal technology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=effects" title="effects">effects</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a>, <a href="https://publications.waset.org/abstracts/search?q=utilization" title=" utilization"> utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=sources" title=" sources"> sources</a>, <a href="https://publications.waset.org/abstracts/search?q=waste" title=" waste"> waste</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination" title=" contamination"> contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/16098/consequential-effects-of-coal-utilization-on-urban-water-supply-sources-a-study-of-ajali-river-in-enugu-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16098.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">423</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">10241</span> Variation in Water Utilization of Typical Desert Shrubs in a Desert-Oasis Ecotone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hai%20Zhou">Hai Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Wenzhi%20Zhao"> Wenzhi Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water is one of the most important factors limiting plant growth and development in desert ecosystems. In order to understand how desert shrubs cope with variation in water sources over time, it is important to understand plant–water relations in desert-oasis ecotone. We selected the typical desert shrubs: Nitraria sibirica, Calligonum mongolicum and Haloxylon ammodendron of 5-, 10-, 20- and 40-year old as the research species, to study the seasonal variation of plant water sources and response to precipitation in the desert-oasis ecotone of Linze, Northwestern China. We examined stable isotopic ratios of oxygen (δ18O) in stem water of desert shrubs as well as in precipitation, groundwater, and soil water in different soil layers and seasons to determine water sources for the shrubs. We found that the N. sibirica and H. ammodendron of 5-, 10-year old showed significant seasonal variation characteristics of δ18O value of stem water and water sources. However, the C. mongolicum and 20- and 40-year H. ammodendron main water sources were from deep soil water and groundwater, and less response to precipitation pulse. After 22.4 mm precipitation, the contribution of shallow soil water (0-50cm) to the use of N. sibirica increased from 6.7% to 36.5%; the C. mongolicum rarely use precipitation that were about 58.29% and 23.51%, absorbed from the deep soil water and groundwater; the contribution of precipitation to use of H. ammodendron had significantly differences among the four ages. The H. ammodendron of 5- and 10-year old about 86.3% and 42.5% water sources absorbed from the shallow soil water after precipitation. However, the contribution to 20- and 40-year old plant was less than 15%. So, the precipitation was one of the main water sources for desert shrubs, but the species showed different water utilization. We conclude that the main water source of the N. sibirica and H. ammodendron of 5-, 10-year was soil water recharged by precipitation, but the deeply rooted H. ammodendron of 20‐ and 40‐year‐old and the C. mongolicum have the ability to exploit a deep and reliable water source. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20use%20pattern" title="water use pattern">water use pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resource" title=" water resource"> water resource</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=seasonal%20change" title=" seasonal change"> seasonal change</a>, <a href="https://publications.waset.org/abstracts/search?q=precipitation%20pulse" title=" precipitation pulse"> precipitation pulse</a> </p> <a href="https://publications.waset.org/abstracts/77818/variation-in-water-utilization-of-typical-desert-shrubs-in-a-desert-oasis-ecotone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77818.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">429</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">10240</span> An Overview of Sludge Utilization into Fired Clay Brick</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aeslina%20Binti%20Abdul%20Kadir">Aeslina Binti Abdul Kadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Shayuti%20Bin%20Abdul%20Rahim"> Ahmad Shayuti Bin Abdul Rahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brick is one of the most common masonry units used as building material. Due to the demand, different types of waste have been investigated to be incorporated into the bricks. Many types of sludge have been incorporated in fired clay brick for example marble sludge, stone sludge, water sludge, sewage sludge, and ceramic sludge. The utilization of these waste materials in fired clay bricks usually has positive effects on the properties such as lightweight bricks with improved shrinkage, porosity, and strength. This paper reviews on utilization of different types of sludge wastes into fired clay bricks. Previous investigations have demonstrated positive effects on the physical and mechanical properties as well as less impact towards the environment. Thus, the utilizations of sludge waste could produce a good quality of brick and could be one of alternative disposal methods for the sludge wastes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fired%20clay%20brick" title="fired clay brick">fired clay brick</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20waste" title=" sludge waste"> sludge waste</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption" title=" water absorption"> water absorption</a> </p> <a href="https://publications.waset.org/abstracts/11628/an-overview-of-sludge-utilization-into-fired-clay-brick" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11628.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">446</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">10239</span> Green Technology for the Treatment of Industrial Effluent Contaminated with Dyes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afzaal%20Gulzar">Afzaal Gulzar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shafaq%20Mubarak"> Shafaq Mubarak</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Zia-Ur-Rehman"> M.

The developed technique not only used to treat contaminated waters but also resulted in the utilization of poultry eggshell waste which in turn assists in solid waste management. Batch sorption studies like contact time, adsorbent dose, dye concentration, temp and pH has been conducted to find the optimum adsorption parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20technology" title="green technology">green technology</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20waste%20management" title=" solid waste management"> solid waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20effluent" title=" industrial effluent"> industrial effluent</a>, <a href="https://publications.waset.org/abstracts/search?q=eggshell%20waste%20utilization" title=" eggshell waste utilization"> eggshell waste utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water%20treatment" title=" waste water treatment"> waste water treatment</a> </p> <a href="https://publications.waset.org/abstracts/11994/green-technology-for-the-treatment-of-industrial-effluent-contaminated-with-dyes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11994.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">10238</span> Effect of Permeability Reducing Admixture Utilization on Sulfate Resistance of Self-Consolidating Concrete Mixture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mardani-Aghabaglou">Ali Mardani-Aghabaglou</a>, <a href="https://publications.waset.org/abstracts/search?q=Zia%20Ahmad%20Faqiri"> Zia Ahmad Faqiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Semsi%20Yazici"> Semsi Yazici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of permeability reducing admixture (PRA) utilization on fresh properties, compressive strength and sulfate resistance of self-consolidating concrete (SSC) were investigated. For this aim, two different commercial PRA were used at two utilization ratios as %0.1 and %0.2 wt. CEM I 42.5 R type cement and crushed limestone aggregate having Dmax of 15 mm were used for preparing of SCC mixtures. In all mixtures, cement content, water/cement ratio, and flow value were kept constant as 450 kg, 0.40 and 65 ± 2 cm, respectively. In order to obtain desired flow value, a polycarboxylate ether-based high range water reducing admixture was used at different content. T50 flow time, flow value, L-box, and U-funnel of SCC mixture were measured as fresh properties. 1, 3, 7 and 28-day compressive strength of SCC mixture were obtained on 150 mm cubic specimens. To investigate the sulfate resistance of SCC mixture 75x75x285 mm prismatic specimens were produced. After 28-day water curing, specimens were immersed in %5 sodium sulfate solution during 210 days. The length change of specimens was measured at 5-day time intervals up to 210 days. According to the test results, all fresh properties of SCC mixtures were in accordance with the European federation of specialist construction chemicals and concrete systems (EFNARC) critter for SCC mixtures. The utilization of PRA had no significant effect on compressive strength and fresh properties of SCC mixtures. Regardless of PRA type, sulfate resistance of SCC mixture increased by adding of PRA into the SCC mixtures. The length changes of the SCC mixtures containing %1 and %2 PRA were measured as %8 and %14 less than that of control mixture containing no PRA, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permeability%20reducing%20admixture" title="permeability reducing admixture">permeability reducing admixture</a>, <a href="https://publications.waset.org/abstracts/search?q=self-consolidating%20concrete" title=" self-consolidating concrete"> self-consolidating concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20properties" title=" fresh properties"> fresh properties</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfate%20resistance" title=" sulfate resistance"> sulfate resistance</a> </p> <a href="https://publications.waset.org/abstracts/99509/effect-of-permeability-reducing-admixture-utilization-on-sulfate-resistance-of-self-consolidating-concrete-mixture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99509.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">157</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">10237</span> Drought Resilient Water Supply for Livelihood: Establishment of Groundwater Treatment Plant at Construction Sites in Taichung City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shang-Hsin%20Ou">Shang-Hsin Ou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang-Chun%20Lin"> Yang-Chun Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ke-Hao%20Cheng"> Ke-Hao Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The year 2021 marked a historic drought in Taiwan, posing unprecedented challenges due to record-low rainfall and inadequate reservoir storage. The central region experienced water scarcity, leading to the implementation of "Groundwater Utilization at Construction Sites" for drought-resilient livelihood water supply. This study focuses on the establishment process of temporary groundwater treatment plants at construction sites in Taichung City, serving as a reference for future emergency response and the utilization of construction site groundwater. To identify suitable sites for groundwater reuse projects, site selection operations were carried out based on relevant water quality regulations and assessment principles. Subsequently, the planning and design of temporary water treatment plants were conducted, considering the water quality, quantity, and on-site conditions of groundwater wells associated with construction projects. The study consolidates the major water treatment facilities at each site and addresses encountered challenges during the establishment process. Practical insights gained from operating temporary groundwater treatment plants are presented, including improvements related to stable water quality, water quantity, equipment operation, and hydraulic control. In light of possible future droughts, this study provides an outlook and recommendations to expedite and improve the setup of groundwater treatment plants at construction sites. This includes considering on-site water abstraction, treatment, and distribution conditions. The study's results aim to offer practical guidelines for effectively establishing and managing such treatment plants, while offering experiences and recommendations for other regions facing similar emergencies, water shortages, and drought situations. These endeavors contribute to ensuring sustainable water supply for drought-resilient livelihoods and maintaining societal stability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drought%20resilience" title="drought resilience">drought resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20treatment" title=" groundwater treatment"> groundwater treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20site" title=" construction site"> construction site</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20supply" title=" water supply"> water supply</a> </p> <a href="https://publications.waset.org/abstracts/167631/drought-resilient-water-supply-for-livelihood-establishment-of-groundwater-treatment-plant-at-construction-sites-in-taichung-city" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167631.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">82</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">10236</span> Utilization of Low-Cost Adsorbent Fly Ash for the Removal of Phenol from Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ihsanullah">Ihsanullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Muataz%20Ali%20Atieh"> Muataz Ali Atieh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a low-cost adsorbent carbon fly ash (CFA) was used for the removal of Phenol from the water.

Azab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shortage of fresh water is a major problem in several areas of the world such as arid regions and coastal zones in several countries of Arabian Gulf. Fortunately, arid regions are exposed to high levels of solar irradiation most the year, which makes the utilization of solar energy a promising solution to such problem with zero harmful emission (Green System). The main objective of this work is to conduct a feasibility study of utilizing small autonomous water desalination units powered by photovoltaic modules as a green renewable energy resource to be employed in different isolated zones as a source of drinking water for some scattered societies where the installation of huge desalination stations are discarded owing to the unavailability of electric grid. Yanbu City is chosen as a case study where the Renewable Energy Center exists and equipped with all sensors to assess the availability of solar energy all over the year. The study included two types of available water: the first type is brackish well water and the second type is seawater of coastal regions. In the case of well water, two versions of desalination units are involved in the study: the first version is based on day operation only. While the second version takes into consideration night operation also, which requires energy storage system as batteries to provide the necessary electric power at night. According to the feasibility study results, it is found that utilization of small autonomous desalinations unit is applicable and economically accepted in the case of brackish well water. While in the case of seawater the capital costs are extremely high and the cost of desalinated water will not be economically feasible unless governmental subsidies are provided. In addition, the study indicated that, for the same water production, the utilization of energy storage version (day-night) adds additional capital cost for batteries, and extra running cost for their replacement, which makes the unit price not only incompetent with day-only unit but also with conventional units powered by diesel generator (fossil fuel) owing to the low prices of fuel in the kingdom. However, the cost analysis shows that the price of the produced water per cubic meter of day-night unit is similar to that produced from the day-only unit provided that the day-night unit operates theoretically for a longer period of 50%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title="solar energy">solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20desalination" title=" water desalination"> water desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20osmosis" title=" reverse osmosis"> reverse osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=arid%20regions" title=" arid regions"> arid regions</a> </p> <a href="https://publications.waset.org/abstracts/16602/feasibility-of-small-autonomous-solar-powered-water-desalination-units-for-arid-regions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16602.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">454</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">10234</span> Optimization of Dez Dam Reservoir Operation Using Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Nikbakht%20Shahbazi">Alireza Nikbakht Shahbazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Emadeddin%20Shirali"> Emadeddin Shirali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since optimization issues of water resources are complicated due to the variety of decision making criteria and objective functions, it is sometimes impossible to resolve them through regular optimization methods or, it is time or money consuming. Therefore, the use of modern tools and methods is inevitable in resolving such problems. An accurate and essential utilization policy has to be determined in order to use natural resources such as water reservoirs optimally. Water reservoir programming studies aim to determine the final cultivated land area based on predefined agricultural models and water requirements. Dam utilization rule curve is also provided in such studies. The basic information applied in water reservoir programming studies generally include meteorological, hydrological, agricultural and water reservoir related data, and the geometric characteristics of the reservoir. The system of Dez dam water resources was simulated applying the basic information in order to determine the capability of its reservoir to provide the objectives of the performed plan. As a meta-exploratory method, genetic algorithm was applied in order to provide utilization rule curves (intersecting the reservoir volume). MATLAB software was used in order to resolve the foresaid model. Rule curves were firstly obtained through genetic algorithm. Then the significance of using rule curves and the decrease in decision making variables in the system was determined through system simulation and comparing the results with optimization results (Standard Operating Procedure). One of the most essential issues in optimization of a complicated water resource system is the increasing number of variables. Therefore a lot of time is required to find an optimum answer and in some cases, no desirable result is obtained. In this research, intersecting the reservoir volume has been applied as a modern model in order to reduce the number of variables. Water reservoir programming studies has been performed based on basic information, general hypotheses and standards and applying monthly simulation technique for a statistical period of 30 years. Results indicated that application of rule curve prevents the extreme shortages and decrease the monthly shortages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=rule%20curve" title=" rule curve"> rule curve</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm%20method" title=" genetic algorithm method"> genetic algorithm method</a>, <a href="https://publications.waset.org/abstracts/search?q=Dez%20dam%20reservoir" title=" Dez dam reservoir"> Dez dam reservoir</a> </p> <a href="https://publications.waset.org/abstracts/40791/optimization-of-dez-dam-reservoir-operation-using-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40791.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">10233</span> Water Absorption Studies on Natural Fiber Reinforced Polymer Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20L.%20Devnani">G.

Therefore, in order to take maximum advantage of these novel materials, one should have a complete understanding of their moisture or water absorption phenomena. Various fiber surface treatment methods like alkaline treatment, acetylation etc. have also been suggested for reduction in water absorption of these composites. In the present study, a detailed review is done for water absorption behavior of natural fiber reinforced polymer composites, and experiments also have been performed on these composites with varying the parameters like fiber loading etc. for understanding the water absorption kinetics.

Carbon Capture, Utilization, and Storage (CCUS) is a topic which is a tool to deal with this CO₂ realization. Flue gas is drawn down from the chimney and filtered, then it is compressed to build up the pressure until 8 bar. This compressed flue gas is sent to three stages Pressure Swing Adsorption (PSA), which is filled with activated carbon. Experiments were showed the optimum adsorption pressure at 7bar, which CO₂ can be adsorbed step by step in 1st, 2nd, and 3rd stage, obtaining CO₂ concentration 29.8, 66.4, and 96.7 %, respectively. The mixed gas concentration from the last step is composed of 96.7% CO₂,2.7% N₂, and 0.6%O₂. This mixed CO₂product gas obtained from 3 stages PSA contained high concentration CO₂, which is ready to use for methanol synthesis. The mixed CO₂ was experimented in 5 Liter/Day of methanol synthesis reactor skid by 3 step processes as followed steam reforming, reverse water gas shift, and then hydrogenation.

Irrigation schedule based on local environmental conditions, soil type and water availability will allow a sustainable use of water resources in agriculture. In this study, the FAO crop water model (AquaCrop) was used to simulate the different water and fertilizer management strategies in different location of Bangladesh to obtain a management guideline for the farmer. Model was calibrated and validated for wheat (Triticum aestivum L.). The statistical indices between the observed and simulated grain yields obtained were very good with R2, RMSE, and EF values of 0.92, 0.33, and 0.83, respectively for model calibration and 0.92, 0.68 and 0.77, respectively for model validations. Stem elongation (jointing) to booting and flowering stage were identified as most water sensitive for wheat. Deficit irrigation on water sensitive stage could increase the grain yield for increasing soil fertility levels both for loamy and sandy type soils. Deficit irrigation strategies provides higher water productivity than full irrigation strategies and increase the yield stability (reduce the standard deviation). The practical deficit irrigation schedule for wheat for four different stations and two different soils were designed. Farmer can produce more crops by using deficit irrigation schedule under water stress condition.

In some areas, it is progressing more slowly. In other areas, irreversible damage has already occurred, rendering regions largely unsuitable for human existence with destruction of the environment and the economy. Today, 2.5 billion people or 36 percent of the world population live in water-stressed areas. The convergence of factors that created this global water crisis includes local, regional, and global failures. In this paper, a survey of some of these factors is presented. They include abuse of political power and regulatory acquiescence, improper planning and design, ignoring good science and models, systemic failures, and division between the powerful and the powerless. Increasing water demand imposed by exploding human populations and growing economies with short-falls exacerbated by climate change and continuing water quality degradation will accelerate this growing water crisis in many areas. Without regional measures to improve water efficiencies and protect dwindling and vulnerable water resources, environmental and economic displacement of populations and conflict over water resources will only grow. Perhaps more challenging, a global commitment is necessary to curtail if not reverse the devastating effects of climate change. Factors will be illustrated by real-world examples, followed by some partial solutions offered by water experts for helping to mitigate the growing water crisis. These solutions include more water efficient technologies, education and incentivization for water conservation, wastewater treatment for reuse, and improved data collection and utilization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20conservation" title=" water conservation"> water conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20crisis" title=" water crisis"> water crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20technologies" title=" water technologies"> water technologies</a> </p> <a href="https://publications.waset.org/abstracts/60880/keynote-talk-some-underlying-factors-and-partial-solutions-to-the-global-water-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60880.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">235</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">10228</span> Social Network Analysis in Water Governance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faribaebrahimi">Faribaebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Ghorbani"> Mehdi Ghorbani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Mohsenisaravi"> Mohsen Mohsenisaravi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ecosystem management is complex because of natural and human issues. To cope with this complexity water governance is recommended since it involves all stakeholders including people, governmental and non-governmental organization who related to environmental systems. Water governance emphasizes on water co-management through consideration of all the stakeholders in the form of social and organizational network. In this research, to illustrate indicators of water governance in Dorood watershed, in Shemiranat region of Iran, social network analysis had been applied. The results revealed that social cohesion among pastoralists in Dorood is medium because of trust links, while link sustainability is weak to medium. According to the results, some pastoralists have high social power and therefore are key actors in the utilization network, regarding to centrality index and trust links. The results also demonstrated that Agricultural Development Office and (Shemshak-Darbandsar Islamic) Council are key actors in rangeland co-management, based on centrality index in rangeland institutional network at regional scale in Shemiranat district. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20network%20analysis" title="social network analysis">social network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20governance" title=" water governance"> water governance</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20network" title=" organizational network"> organizational network</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20co-management" title=" water co-management"> water co-management</a> </p> <a href="https://publications.waset.org/abstracts/37465/social-network-analysis-in-water-governance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37465.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">351</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">10227</span> An Alternative Institutional Design for Efficient Management of Nepalese Irrigation Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tirtha%20Raj%20Dhakal">Tirtha Raj Dhakal</a>, <a href="https://publications.waset.org/abstracts/search?q=Brian%20Davidson"> Brian Davidson</a>, <a href="https://publications.waset.org/abstracts/search?q=Bob%20Farquharson"> Bob Farquharson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Institutional design is important if water resources are to be managed efficiently. In Nepal, the supply of water in both farmer- and agency-managed irrigation systems is inefficient because of the weak institutional frameworks. This type of inefficiency is linked with collective problems such as non-excludability of irrigation water, inadequate recognition of property rights and externalities. Irrigation scheme surveys from Nepal as well as existing literature revealed that the Nepalese irrigation sector is facing many issues such as low cost recovery, inadequate maintenance of the schemes and inefficient allocation and utilization of irrigation water. The institutional practices currently in place also fail to create/force any incentives for farmers to use water efficiently and to pay for its use. This, thus, compels the need of refined institutional framework that can address the collective problems and improve irrigation efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agency-managed" title="agency-managed">agency-managed</a>, <a href="https://publications.waset.org/abstracts/search?q=cost%20recovery" title=" cost recovery"> cost recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer-managed" title=" farmer-managed"> farmer-managed</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20design" title=" institutional design"> institutional design</a> </p> <a href="https://publications.waset.org/abstracts/62687/an-alternative-institutional-design-for-efficient-management-of-nepalese-irrigation-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62687.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">424</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">10226</span> A Performance Analysis Study of an Active Solar Still Integrating Fin at the Basin Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20Ansari">O.

Water-level continues declining year after year and it is primarily caused by sustained, extensive, and traditional usage methods. Improving water utilization becomes an urgent issue in order satisfy the increasing population needs. Desalination of seawater or brackish water could help in increasing water potential. However, a cost-effective desalination process is required. The most appropriate method for performing this desalination is solar-driven distillation, given its simplicity, low cost and especially the availability of the solar energy source. The main objective of this paper is to demonstrate the influence of coupling integrated basin plate by fins with preheating by solar collector on the performance of solar still. The energy balance equations for the various elements of the solar still are introduced. A numerical example is used to show the efficiency of the proposed solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20solar%20still" title="active solar still">active solar still</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=fins" title=" fins"> fins</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20collector" title=" solar collector"> solar collector</a> </p> <a href="https://publications.waset.org/abstracts/79883/a-performance-analysis-study-of-an-active-solar-still-integrating-fin-at-the-basin-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79883.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">217</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">10225</span> Utilization of Coconut Husk and Sugarcane Bagasse as a Natural Component in Making Water Resistance Tote Bags</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cyril%20Mae%20B.%20Mationg">Cyril Mae B.

The contributing causes of shortage in water resources are sophisticated and have interactions with each other. The world-scale phenomena like global warming have led to an increase in air and ocean’s mean temperature, and this has already caused adverse effects on water resources. Other factors that exacerbated this situation such as population increase, changes in farming habits, rise in city dwellers, unbalanced request for energy and aquatic resources, improved living standards, new eating habits, increasing economic growth and consequently flourishing industrial activities, and different types of pollution such as air, water, etc., are compelling more pressure on our limited water resources. The report will briefly discuss climate change and its detrimental impacts on the water resources and finally will introduce two effective solutions to mitigate the consequences or even reverse them in the near to mid-term future: utilization of molten salt technology for storing huge amounts of generated electricity in solar power plants to accommodate power grid demands, and implementing fuel cell CHPs to reduce carbon emission, and consequently, mitigate the global warming phenomenon as the major root cause of threatening water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title=" global warming"> global warming</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell-CHP" title=" fuel cell-CHP"> fuel cell-CHP</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20power%20plant" title=" solar power plant"> solar power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt%20storage" title=" molten salt storage"> molten salt storage</a> </p> <a href="https://publications.waset.org/abstracts/151405/the-effect-of-global-warming-on-water-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151405.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">112</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">10223</span> Gender Responsiveness of Water, Sanitation Policies and Legal Frameworks at Makerere University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harriet%20Kebirungi">Harriet Kebirungi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majaliwa%20Jackson-Gilbert%20Mwanjalolo"> Majaliwa Jackson-Gilbert Mwanjalolo</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Livingstone%20Luboobi"> S.

The objectives of the study were to i) examine the gender responsiveness of water and sanitation related policies and frameworks implemented at Makerere University; and ii) assess the challenges faced by the University in customizing national water and sanitation policies and legal frameworks into University policies. A cross-sectional gender-focused study design was adopted. A checklist was developed to analyze national water and sanitation policies and legal frameworks and University based policies. In addition, primary data was obtained from Key informants at the Ministry of Water and Environment and Makerere University. A gender responsive five-step analytical framework was used to analyze the collected data. Key findings indicated that the policies did not adequately address issues of gender, water and sanitation and the policies were gender neutral consistently. The national policy formulation process was found to be gender blind and not backed by situation analysis of different stakeholders including higher education institutions like Universities. At Makerere University, due to lack of customized and gender responsive water and sanitation policy and implementation framework, there were gender differences and deficiencies in access to and utilization of water and sanitation facilities. The University should take advantage of existing expertise within them to customize existing national water policies and gender, and water and sanitation sub-sector strategy. This will help the University to design gender responsive, culturally acceptable and environmental friendly water and sanitation systems that provide adequate water and sanitation facilities that address the needs and interests of male and female students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=Makerere%20University" title=" Makerere University"> Makerere University</a>, <a href="https://publications.waset.org/abstracts/search?q=policies" title=" policies"> policies</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=sanitation" title=" sanitation"> sanitation</a> </p> <a href="https://publications.waset.org/abstracts/70074/gender-responsiveness-of-water-sanitation-policies-and-legal-frameworks-at-makerere-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70074.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">403</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">10222</span> Utilization of Two Kind of Recycling Greywater in Irrigation of Syngonium SP.

The novel aspects of the process lie in a series of bioreactors that specially arrange and design to meet the required conditions for water purification. The BAS maximizes the utilization of bio-balls as the ideal surface for beneficial microbes to flourish. It also serves as a physical barrier that traps organic particles, which in turn becomes source for the microbes to perform their work. The operation in the proposed system gives a low concentration and average range of good maintain excellent water quality, i.e., with low levels of ammonia, nitrite, nitrate, a suitable pH range for aquaculture and low turbidity. The BAS thus provides a solution for sustainable small-scale, urban aquaculture operation with a high recovery water and minimal waste disposal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammonia" title="ammonia">ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=bioreactor" title=" bioreactor"> bioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=Biological%20Aquaculture%20System%20%28BAS%29" title=" Biological Aquaculture System (BAS)"> Biological Aquaculture System (BAS)</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-balls" title=" bio-balls"> bio-balls</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20recirculating%20technology" title=" water recirculating technology"> water recirculating technology</a> </p> <a href="https://publications.waset.org/abstracts/19005/biological-aquaculture-system-bas-design-and-water-quality-on-marble-goby-oxyeleotris-marmoratus-a-water-recirculating-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19005.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">592</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">10220</span> The Prototype of the Solar Energy Utilization for the Finding Sustainable Conditions in the Future: The Solar Community with 4000 Dwellers 960 Families, equal to 480 Solar Dwelling Houses and 32 Mansion Buildings (480 Dwellers)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kunihisa%20Kakumoto">Kunihisa Kakumoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This technical paper is for the prototype of solar energy utilization for finding sustainable conditions.

For the finding sustainable conditions, the amount of the solar energy generation and its reduction of carbon dioxide and the reduction of carbon dioxide by the green planting and the amount of carbon dioxide according to the normal daily life in the solar community and the amount of the necessary water for the daily life in the solar community and the amount of the water supply by the rainfall on-site were calculated. These all values were taken into consideration. The relations between each calculated result are shown in the expression of inequality. This solar community and its consideration for finding sustainable conditions can be one prototype to do the feasibility study for our life in the future <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title="carbon dioxide">carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20planting" title=" green planting"> green planting</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20community" title=" solar community"> solar community</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20condition" title=" sustainable condition"> sustainable condition</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20activity" title=" water activity"> water activity</a> </p> <a href="https://publications.waset.org/abstracts/131638/the-prototype-of-the-solar-energy-utilization-for-the-finding-sustainable-conditions-in-the-future-the-solar-community-with-4000-dwellers-960-families-equal-to-480-solar-dwelling-houses-and-32-mansion-buildings-480-dwellers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131638.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">287</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">10219</span> Exercise in Extreme Conditions: Leg Cooling and Fat/Carbohydrate Utilization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anastasios%20Rodis">Anastasios Rodis </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Case studies of walkers, climbers, and campers exposed to cold and wet conditions without limb water/windproof protection revealed experiences of muscle weakness and fatigue. It is reasonable to assume that a part of the fatigue could occur due to an alteration in substrate utilization, since reduction of performance in extreme cold conditions, may partially be explained by higher anaerobic glycolysis, reflecting higher carbohydrate oxidation and an increase accumulation rate of blood lactate. The aim of this study was to assess the effects of pre-exercise lower limb cooling on substrate utilization rate during sub-maximal exercise. Method: Six male university students (mean (SD): age, 21.3 (1.0) yr; maximal oxygen uptake (V0₂ max), 49.6 (3.6) ml.min⁻¹; and percentage of body fat, 13.6 (2.5) % were examined in random order after either 30min cold water (12°C) immersion utilized as the cooling strategy up to the gluteal fold, or under control conditions (no precooling), with tests separated by minimum of 7 days. Exercise consisted of 60min cycling at 50% V0₂ max, in a thermoneutral environment of 20°C. Subjects were also required to record a diet diary over the 24hrs prior to the each trial. Means (SD) for the three macronutrients during the 1 day prior to each trial (expressed as a percentage of total energy) 52 (3) % carbohydrate, 31 (4) % fat, and 17 (± 2) % protein. Results: The following responses to lower limb cooling relative to control trial during exercise were: 1) Carbohydrate (CHO) oxidation, and blood lactate (Bₗₐc) concentration were significantly higher (P < 0.05); 2) rectal temperature (Tᵣₑc) was significantly higher (P < 0.05), but skin temperature was significantly lower (P < 0.05); no significant differences were found in blood glucose (Bg), heart rate (HR) and oxygen consumption (V0₂). Discussion: These data suggested that lower limb cooling prior to submaximal exercise will shift metabolic processes from Fat oxidation to CHO oxidation. This shift from Fat to CHO oxidation will probably have important implications in the surviving scenario, since people facing accidental localized cooling of their limbs either through wading/falling in cold water or snow even if they do not perform high intensity activity, they have to rely on CHO availability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exercise%20in%20wet%20conditions" title="exercise in wet conditions">exercise in wet conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=leg%20cooling" title=" leg cooling"> leg cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=outdoors%20exercise" title=" outdoors exercise"> outdoors exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate%20utilization" title=" substrate utilization"> substrate utilization</a> </p> <a href="https://publications.waset.org/abstracts/70033/exercise-in-extreme-conditions-leg-cooling-and-fatcarbohydrate-utilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70033.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">440</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">10218</span> Load Balancing and Resource Utilization in Cloud Computing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gagandeep%20Kaur">Gagandeep Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cloud computing uses various computing resources such as CPU, memory, processor etc. which is used to deliver service over the network and is one of the emerging fields for large scale distributed computing. In cloud computing, execution of large number of tasks with available resources to achieve high performance, minimal total time for completion, minimum response time, effective utilization of resources etc. are the major research areas. In the proposed research, an algorithm has been proposed to achieve high performance in load balancing and resource utilization. The proposed algorithm is used to reduce the makespan, increase the resource utilization and performance cost for independent tasks. Further scheduling metrics based on algorithm in cloud computing has been proposed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resource%20utilization" title="resource utilization">resource utilization</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20time" title=" response time"> response time</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20balancing" title=" load balancing"> load balancing</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20cost" title=" performance cost"> performance cost</a> </p> <a href="https://publications.waset.org/abstracts/140764/load-balancing-and-resource-utilization-in-cloud-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140764.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">182</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">10217</span> Characterization of High Carbon Ash from Pulp and Paper mill for Potential Utilization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruma%20Rano">Ruma Rano</a>, <a href="https://publications.waset.org/abstracts/search?q=Firoza%20Sultana"> Firoza Sultana</a>, <a href="https://publications.waset.org/abstracts/search?q=Bishal%20Bhuyan"> Bishal Bhuyan</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurul%20Alam%20Mazumder"> Nurul Alam Mazumder</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fly ash collected from Cachar Paper Mill, Assam, India has been thoroughly characterized in respect of its physico-chemical, morphological and mineralogical features were concerned by using density, LOI, FTIR, XRD, SEM-EDS etc. The results reveal that there is a striking difference in the features and properties of the coarser and finer fractions .The high carbon ash consists of large unburnt carbon (chars), irregular carbonaceous particles in the coarser fraction, which appear to be porous and may be used as domestic fuel. The percentage of char albeit the carbon content decreases with decrease in size of particles. The various fractions essentially contain quartz and mullite as the main mineral phases. For suggesting the potential utilization channels, number of experiments were performed correlating the total characteristic features. Water holding capacities of different size classified fractions were determined, the coarser fractions have unexpectedly higher water holding capacities than the finer ones. An attempt has been made to correlate the results obtained with potential use in agriculture. Another potential application of coarser particles is used as adsorbent for effluents containing waste organic materials. Thus thorough characterization leads to not only a definite direction about the uses of the value added components but also gives useful information regarding the prevailing combustion process. <p
