The physical, chemical and bacteriological quality of the water contributed from each of these water-bearing formations and resultant effects of indiscriminate wastes disposal will be dependent on the dissolution of material within the formation. Therefore, water withdrawn from any ground water source will be a composite of these individual aquifers. The water quality was determined by actual sampling and analysis of the completed wells. This study attempted to examine the physicochemical and bacteriological water quality of twenty five selected wells comprising twenty boreholes (deep wells) and five hand dug wells (shallow wells). The twenty five wells cut across the entire Ado Ekiti Metropolitan area. The water samples collected using standard method was promptly taken to water laboratory at the Federal Polytechnic Ado-Ekiti for analysis, physical, chemical and bacteriological tests were carried out. Quality characteristics tested were found to meet WHO’s standard and generally acceptable, making it potable for drinking in most situations, thus encouraging the use of groundwater. Possible improvement strategies to groundwater exploitation were highlighted while remedies to poor quality water were suggested. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteriological" title="bacteriological">bacteriological</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical" title=" physicochemical"> physicochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=wells" title=" wells"> wells</a>, <a href="https://publications.waset.org/abstracts/search?q=Ado%20Ekiti" title=" Ado Ekiti"> Ado Ekiti</a> </p> <a href="https://publications.waset.org/abstracts/35884/physicochemical-and-bacteriological-quality-characterization-of-some-selected-wells-in-ado-ekiti-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">368</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1072</span> A Psycholinguistic Analysis of John Nash’s Hallucinations as Represented in the Film “A Beautiful Mind”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizkia%20Shafarini">Rizkia Shafarini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The film A Beautiful Mind explores hallucination in this study. A Beautiful Mind depicts the tale of John Nash, a university student who dislikes studying in class or prefers to study alone. Throughout his life, John Nash has hallucinated, or what is known as schizophrenia, as depicted in the film A Beautiful Mind. The goal of this study was to figure out what hallucinations were, what caused them, and how John Nash managed his hallucinations. In general, this study examines the link between language and mind, or the linguistic relationship portrayed in John Nash's character's speech, as evidenced by his conduct. This study takes a psycholinguistic approach to data analysis by employing qualitative methodologies. Data sources include talks and scenes from the film A Beautiful Mind. Hearing, seeing, and feeling are the scientific results of John Nash's hallucinations in the film A Beautiful Mind. Second, dreams, aspirations, and sickness are the sources of John Nash's hallucinations. Third, John Nash's method of managing hallucinations is to see a doctor without medical or distracting assistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=A%20Beautiful%20Mind" title="A Beautiful Mind">A Beautiful Mind</a>, <a href="https://publications.waset.org/abstracts/search?q=hallucination" title=" hallucination"> hallucination</a>, <a href="https://publications.waset.org/abstracts/search?q=psycholinguistic" title=" psycholinguistic"> psycholinguistic</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Nash" title=" John Nash"> John Nash</a> </p> <a href="https://publications.waset.org/abstracts/144856/a-psycholinguistic-analysis-of-john-nashs-hallucinations-as-represented-in-the-film-a-beautiful-mind" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144856.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">168</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">1071</span> Effect of Blade Shape on the Performance of Wells Turbine for Wave Energy Conversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katsuya%20Takasaki">Katsuya Takasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Manabu%20Takao"> Manabu Takao</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshiaki%20Setoguchi"> Toshiaki Setoguchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Effect of 3-dimensional (3D) blade on the turbine characteristics of Wells turbine for wave energy conversion has been investigated experimentally by model testing under steady flow conditions in the study, in order to improve the peak efficiency and the stall characteristics. The aim of the use of 3D blade is to prevent flow separation on the suction surface near the tip. The chord length is constant with radius and the blade profile changes gradually from mean radius to tip. The proposed blade profiles in the study are NACA0015 from hub to mean radius and NACA0025 at the tip. The performances of Wells turbine with 3D blades has been compared with those of the original Wells turbine, i.e. the turbine with 2-dimensional (2D) blades. As a result, it was concluded that although the peak efficiency of Wells turbine can be improved by the use of the proposed 3D blade, its blade does not overcome the weakness of stalling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluid%20machinery" title="fluid machinery">fluid machinery</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean%20engineering" title=" ocean engineering"> ocean engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=stall" title=" stall"> stall</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20energy%20conversion" title=" wave energy conversion"> wave energy conversion</a>, <a href="https://publications.waset.org/abstracts/search?q=wells%20turbine" title=" wells turbine"> wells turbine</a> </p> <a href="https://publications.waset.org/abstracts/17316/effect-of-blade-shape-on-the-performance-of-wells-turbine-for-wave-energy-conversion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17316.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">305</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">1070</span> Water Budget in High Drought-Borne Area in Jaffna District, Sri Lanka during Dry Season</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Kandiah">R.

Miyamoto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Sri Lanka, the Jaffna area is a high drought affected area and depends mainly on groundwater aquifers for water needs. Water for daily activities is extracted from wells. As households manually extract water from the wells, it is not drawn from mid evening to early morning. The water inflow at night provides the maximum water level that decreases during the daytime due to extraction. The storage volume of water in wells is limited or at its lowest level during the dry season. This study analyzes the domestic water budget during the dry season in the Jaffna area. In order to evaluate the water inflow rate into wells, storage volume and extraction volume from wells over time, water pressure is measured at the bottom of three wells, which are located in coastal area denoted as well A, in nonspecific area denoted as well B, and agricultural area denoted as well C. The water quality at the wells A, B, and C, are mostly fresh, modest fresh, and saline respectively. From the monitoring, we can find that the daily inflow amount of water into the wells and daily water extraction depend on each other, that is, higher extraction yields higher inflow. And, in the dry season, the daily inflow volume and the daily extraction volume of each well are almost in balance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accessible%20volume" title="accessible volume">accessible volume</a>, <a href="https://publications.waset.org/abstracts/search?q=consumption%20volume" title=" consumption volume"> consumption volume</a>, <a href="https://publications.waset.org/abstracts/search?q=inflow%20rate" title=" inflow rate"> inflow rate</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20budget" title=" water budget"> water budget</a> </p> <a href="https://publications.waset.org/abstracts/44906/water-budget-in-high-drought-borne-area-in-jaffna-district-sri-lanka-during-dry-season" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44906.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">358</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">1069</span> Oil Producing Wells Using a Technique of Gas Lift on Prosper Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikhil%20Yadav">Nikhil Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubham%20Verma"> Shubham Verma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gas lift is a common technique used to optimize oil production in wells. Prosper software is a powerful tool for modeling and optimizing gas lift systems in oil wells. This review paper examines the effectiveness of Prosper software in optimizing gas lift systems in oil-producing wells. The literature review identified several studies that demonstrated the use of Prosper software to adjust injection rate, depth, and valve characteristics to optimize gas lift system performance. The results showed that Prosper software can significantly improve production rates and reduce operating costs in oil-producing wells. However, the accuracy of the model depends on the accuracy of the input data, and the cost of Prosper software can be high. Therefore, further research is needed to improve the accuracy of the model and evaluate the cost-effectiveness of using Prosper software in gas lift system optimization <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20lift" title="gas lift">gas lift</a>, <a href="https://publications.waset.org/abstracts/search?q=prosper%20software" title=" prosper software"> prosper software</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20rate" title=" injection rate"> injection rate</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20costs" title=" operating costs"> operating costs</a>, <a href="https://publications.waset.org/abstracts/search?q=oil-producing%20wells" title=" oil-producing wells"> oil-producing wells</a> </p> <a href="https://publications.waset.org/abstracts/167194/oil-producing-wells-using-a-technique-of-gas-lift-on-prosper-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167194.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">88</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">1068</span> Aerodynamic Bicycle Torque Augmentation with a Wells Turbine in Wheels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsuyoshi%20Yamazaki">Tsuyoshi Yamazaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Etsuo%20Morishita"> Etsuo Morishita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cyclists often run through a crosswind and sometimes we experience the adverse pressure. We came to an idea that Wells turbine can be used as power augmentation device in the crosswind something like sails of a yacht. Wells turbine always rotates in the same direction irrespective of the incoming flow direction, and we use it in the small-scale power generation in the ocean where waves create an oscillating flow. We incorporate the turbine to the wheel of a bike. A commercial device integrates strain gauges in the crank of a bike and transmitted force and torque applied to the pedal of the bike as an e-mail to the driver’s mobile phone. We can analyze the unsteady data in a spreadsheet sent from the crank sensor. We run the bike with the crank sensor on the rollers at the exit of a low-speed wind tunnel and analyze the effect of the crosswind to the wheel with a Wells turbine. We also test the aerodynamic characteristics of the turbine separately. Although power gain depends on the flow direction, several Watts increase might be possible by the Wells turbine incorporated to a bike wheel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=Wells%20turbine" title=" Wells turbine"> Wells turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=bicycle" title=" bicycle"> bicycle</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20engineering" title=" wind engineering"> wind engineering</a> </p> <a href="https://publications.waset.org/abstracts/84277/aerodynamic-bicycle-torque-augmentation-with-a-wells-turbine-in-wheels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84277.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">180</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">1067</span> Petrology and Hydrothermal Alteration Mineral Distribution of Wells La-9D and La-10D in Aluto Geothermal Field, Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dereje%20Moges%20Azbite">Dereje Moges Azbite</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laboratory analysis of igneous rocks is performed with the help of the main oxide plots.

Moreover, there are two large values of PL intensity in the DPQW, which also differs from the PQW. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Photoluminescence" title="Photoluminescence">Photoluminescence</a>, <a href="https://publications.waset.org/abstracts/search?q=quantum%20wells" title=" quantum wells"> quantum wells</a>, <a href="https://publications.waset.org/abstracts/search?q=quasiperiodic%20structure" title=" quasiperiodic structure"> quasiperiodic structure</a> </p> <a href="https://publications.waset.org/abstracts/21210/characteristics-of-photoluminescence-in-resonant-quasiperiodic-double-period-quantum-wells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21210.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">719</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">1064</span> Economic Evaluation of Bowland Shale Gas Wells Development in the UK</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elijah%20Acquah-Andoh">Elijah Acquah-Andoh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The UK has had its fair share of the shale gas revolutionary waves blowing across the global oil and gas industry at present. Although, its exploitation is widely agreed to have been delayed, shale gas was looked upon favorably by the UK Parliament when they recognized it as genuine energy source and granted licenses to industry to search and extract the resource. This, although a significant progress by industry, there yet remains another test the UK fracking resource must pass in order to render shale gas extraction feasible – it must be economically extractible and sustainably so. Developing unconventional resources is much more expensive and risky, and for shale gas wells, producing in commercial volumes is conditional upon drilling horizontal wells and hydraulic fracturing, techniques which increase CAPEX. Meanwhile, investment in shale gas development projects is sensitive to gas price and technical and geological risks. Using a Two-Factor Model, the economics of the Bowland shale wells were analyzed and the operational conditions under which fracking is profitable in the UK was characterized. We find that there is a great degree of flexibility about Opex spending; hence Opex does not pose much threat to the fracking industry in the UK. However, we discover Bowland shale gas wells fail to add value at gas price of $8/ Mmbtu. A minimum gas price of $12/Mmbtu at Opex of no more than $2/ Mcf and no more than $14.95M Capex are required to create value within the present petroleum tax regime, in the UK fracking industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capex" title="capex">capex</a>, <a href="https://publications.waset.org/abstracts/search?q=economical" title=" economical"> economical</a>, <a href="https://publications.waset.org/abstracts/search?q=investment" title=" investment"> investment</a>, <a href="https://publications.waset.org/abstracts/search?q=profitability" title=" profitability"> profitability</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20gas%20development" title=" shale gas development"> shale gas development</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable" title=" sustainable"> sustainable</a> </p> <a href="https://publications.waset.org/abstracts/29712/economic-evaluation-of-bowland-shale-gas-wells-development-in-the-uk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29712.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">579</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">1063</span> Application of Decline Curve Analysis to Depleted Wells in a Cluster and then Predicting the Performance of Currently Flowing Wells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Satish%20Kumar%20Pappu">Satish Kumar Pappu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The most common questions which are frequently asked in oil and gas industry are how much is the current production rate from a particular well and what is the approximate predicted life of that well. These questions can be answered through forecasting of important realistic data like flowing tubing hole pressures FTHP, Production decline curves which are used predict the future performance of a well in a reservoir. With the advent of directional drilling, cluster well drilling has gained much importance and in-fact has even revolutionized the whole world of oil and gas industry. An oil or gas reservoir can generally be described as a collection of several overlying, producing and potentially producing sands in to which a number of wells are drilled depending upon the in-place volume and several other important factors both technical and economical in nature, in some sands only one well is drilled and in some, more than one. The aim of this study is to derive important information from the data collected over a period of time at regular intervals on a depleted well in a reservoir sand and apply this information to predict the performance of other wells in that reservoir sand. The depleted wells are the most common observations when an oil or gas field is being visited, w the application of this study more realistic in nature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decline%20curve%20analysis" title="decline curve analysis">decline curve analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation%20of%20future%20gas%20reserves" title=" estimation of future gas reserves"> estimation of future gas reserves</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20sands" title=" reservoir sands"> reservoir sands</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20risk%20profile" title=" reservoir risk profile"> reservoir risk profile</a> </p> <a href="https://publications.waset.org/abstracts/34930/application-of-decline-curve-analysis-to-depleted-wells-in-a-cluster-and-then-predicting-the-performance-of-currently-flowing-wells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34930.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">437</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">1062</span> Optimum Dewatering Network Design Using Firefly Optimization Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Javad%20Davoodi">S.

One of the methods to control groundwater in such cases is using pumping wells. These pumping wells remove excess water from the site project and lower the water table to a desirable value. Although the efficiency of this method is acceptable, it needs high expenses to apply. It means even small improvement in a design of pumping wells can lead to substantial cost savings. In order to minimize the total cost in the method of pumping wells, a simulation-optimization approach is applied. The proposed model integrates MODFLOW as the simulation model with Firefly as the optimization algorithm. In fact, MODFLOW computes the drawdown due to pumping in an aquifer and the Firefly algorithm defines the optimum value of design parameters which are numbers, pumping rates and layout of the designing wells. The developed Firefly-MODFLOW model is applied to minimize the cost of the dewatering project for the ancient mosque of Kerman city in Iran. Repetitive runs of the Firefly-MODFLOW model indicates that drilling two wells with the total rate of pumping 5503 m3/day is the result of the minimization problem. Results show that implementing the proposed solution leads to at least 1.5 m drawdown in the aquifer beneath mosque region. Also, the subsidence due to groundwater depletion is less than 80 mm. Sensitivity analyses indicate that desirable groundwater depletion has an enormous impact on total cost of the project. Besides, in a hypothetical aquifer decreasing the hydraulic conductivity contributes to decrease in total water extraction for dewatering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20dewatering" title="groundwater dewatering">groundwater dewatering</a>, <a href="https://publications.waset.org/abstracts/search?q=pumping%20wells" title=" pumping wells"> pumping wells</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation-optimization" title=" simulation-optimization"> simulation-optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=MODFLOW" title=" MODFLOW"> MODFLOW</a>, <a href="https://publications.waset.org/abstracts/search?q=firefly%20algorithm" title=" firefly algorithm"> firefly algorithm</a> </p> <a href="https://publications.waset.org/abstracts/26422/optimum-dewatering-network-design-using-firefly-optimization-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26422.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">294</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">1061</span> Deep Injection Wells for Flood Prevention and Groundwater Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20R.%20Jafari">Mohammad R.

However, the fast-paced rate of infrastructure development in the capital city of Doha has led to recurring instances of surface water flooding as well as rising groundwater levels. Public Work Authority (PWA/ASHGHAL) has implemented an approach to collect and discharge the flood water into a) positive gravity systems; b) Emergency Flooding Area (EFA) – Evaporation, Infiltration or Storage off-site using tankers; and c) Discharge to deep injection wells. As part of the flood prevention scheme, 21 deep injection wells have been constructed to discharge the collected surface and groundwater table in Doha city. These injection wells function as an alternative in localities that do not possess either positive gravity systems or downstream networks that can accommodate additional loads. These injection wells are 400-m deep and are constructed in a complex karstic subsurface condition with large cavities. The injection well system will discharge collected groundwater and storm surface runoff into the permeable Umm Er Radhuma Formation, which is an aquifer present throughout the Persian Gulf Region. The Umm Er Radhuma formation contains saline water that is not being used for water supply. The injection zone is separated by an impervious gypsum formation which acts as a barrier between upper and lower aquifer. State of the art drilling, grouting, and geophysical techniques have been implemented in construction of the wells to assure that the shallow aquifer would not be contaminated and impacted by injected water. Injection and pumping tests were performed to evaluate injection well functionality (injectability). The results of these tests indicated that majority of the wells can accept injection rate of 200 to 300 m<sup>3 </sup>/h (56 to 83 l/s) under gravity with average value of 250 m<sup>3 </sup>/h (70 l/s) compared to design value of 50 l/s. This paper presents design and construction process and issues associated with these injection wells, performing injection/pumping tests to determine capacity and effectiveness of the injection wells, the detailed design of collection system and conveying system into the injection wells, and the operation and maintenance process. This system is completed now and is under operation, and therefore, construction of injection wells is an effective option for flood control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20injection%20well" title="deep injection well">deep injection well</a>, <a href="https://publications.waset.org/abstracts/search?q=flood%20prevention%20scheme" title=" flood prevention scheme"> flood prevention scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=geophysical%20tests" title=" geophysical tests"> geophysical tests</a>, <a href="https://publications.waset.org/abstracts/search?q=pumping%20and%20injection%20tests" title=" pumping and injection tests"> pumping and injection tests</a>, <a href="https://publications.waset.org/abstracts/search?q=wellhead%20assembly" title=" wellhead assembly"> wellhead assembly</a> </p> <a href="https://publications.waset.org/abstracts/101291/deep-injection-wells-for-flood-prevention-and-groundwater-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101291.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">119</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">1060</span> The Review of Coiled Tubing Intelligent Sidetracking Steering Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Xueran">Zhao Xueran</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Dong"> Yang Dong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to improve the problem that old wells in oilfields are shut down due to low oil recovery, sidetracking has become one of the main technical means to restore the vitality of old wells.

On the base of the Geomechanical model (GMM), a methodology was developed for sweet spot intervals and zones for drilling horizontal wells with hydraulic fracturing. Based on mechanical rock typification, eight mechanical rock types (MRT) have been identified. Sweet spot intervals are represented by siliceous-carbonate (2), siliceous (5) and carbonate (8) MRT that have the greatest brittleness index (BRIT). A correlation has been established between the thickness of brittle intervals and the initial well production rates, which makes it possible to identify sweet spot zones for drilling horizontal wells with hydraulic fracturing. Brittle and ductile intervals are separated by a BRIT cut-off of 0.4 since wells located at points with BRIT < 0.4 have insignificant rates (less than 2 m³/day). Wells with an average BRIT in BAUF of more than 0.4 reach industrial production rates. The next application of GMM is associated with the instability of the overburdened clay formation above the top of the BAUF. According to the wellbore stability analysis, the recommended mud weight for this formation must be not less than 1.53–1.55 g/cc. The optimal direction for horizontal wells corresponds to the azimuth of Shmin equal to 70-80°. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconventional%20reservoirs" title="unconventional reservoirs">unconventional reservoirs</a>, <a href="https://publications.waset.org/abstracts/search?q=geomechanics" title=" geomechanics"> geomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=sweet%20spot%20zones" title=" sweet spot zones"> sweet spot zones</a>, <a href="https://publications.waset.org/abstracts/search?q=borehole%20stability" title=" borehole stability"> borehole stability</a> </p> <a href="https://publications.waset.org/abstracts/181212/application-of-a-geomechanical-model-to-justify-the-exploitation-of-bazhenov-abalak-formation-western-siberia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181212.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">67</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">1058</span> Effect of Papaverine on Neurospheres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Noura%20Shehab-Eldeen">Noura Shehab-Eldeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elsherbeeny"> Mohamed Elsherbeeny</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Elmetwally"> Hossam Elmetwally</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salama"> Mohamed Salama</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Lotfy"> Ahmed Lotfy</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elgamal"> Mohamed Elgamal</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Sheashaa"> Hussein Sheashaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sobh"> Mohamed Sobh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mitochondrial toxins including papaverine may be implicated in the etiology and pathogenesis of Parkinson's disease. The aim was to detect the effect of papaverine on the proliferation and viability of neural stem cells. Rat neural progenitor cells were isolated from embryos (E14) brains. The dispersed tissues were allowed to settle, then, The supernatant was centrifuged at 1,000 g for 5 min. The pellet was placed in Hank’s solution cultured as free-floating neurospheres Dulbecco’s modified Eagle medium (DMEM) and Hams F12 (3:1) supplemented with B27 (Invitrogen GmBH, Karlsruhe, Germany), 20 ng/mL epidermal growth factor (EGF; Biosource, Karlsruhe, Germany), 20 ng/mL recombinant human fibroblast growth factor (rhFGF; R&D Systems, Wiesbaden-Nordenstadt, Germany), and penicillin and streptomycin (1:100; Invitrogen) at 37°C with 7.5% CO2 . Differentiation was initiated by growth factor withdrawal and plating onto a poly-d-lysine/ laminin matrix. The neurospheres were fed every 2-3 days by replacing 50% of the culture media with fresh media. The culture suspension was transferred to a dish containing 16 wells. The wells were divided as follows: 4 wells received no papaverine (control), 4 wells 1 u, 4 wells 5 u and 4 wells 10 u of papaverine solution. In the next 2 weeks, photography (0,4,5,11days) and viability test were done. The photographs were analysed. Results : papaverine didn't affect proliferation of neurospheres, while it affected viability compared to control , this was dose related.

Therefore, it is necessary to control water during fracturing in deep coal measure tight gas reservoir. Using fuzzy-ball fluid to control water fracturing can not only increase the output but also reduce the water output. The fuzzy-ball fluid was prepared indoors to carry out evaluation experiments. The fuzzy ball fluid was mixed in equal volume with the pre-fluid and formation water to test its compatibility. The core displacement device was used to test the gas and water breaking through the matrix and fractured cores blocked by fuzzy-ball fluid. The breakthrough pressure of the plunger tests its water blocking performance. The experimental results show that there is no precipitation after the fuzzy-ball fluid is mixed with the pad fluid and the formation water, respectively. The breakthrough pressure gradients of gas and water after the fuzzy-ball fluid plugged the cracks were 0.02MPa/cm and 0.04MPa/cm, respectively, and the breakthrough pressure gradients of gas and water after the matrix was plugged were 0.03MPa/cm and 0.2MPa/cm, respectively, which meet the requirements of field operation. Two wells A and B in the Sulige Gas Field were used on site to implement water control fracturing. After the pre-fluid was injected into the two wells, 50m3 of fuzzy-ball fluid was pumped to plug the water. The construction went smoothly. After water control and fracturing, the average daily output in 161 days was increased by 13.71% and 6.99% compared with that of adjacent wells in the same layer. The adjacent wells were bubbled for 3 times and 63 times respectively, while there was no effusion in A and B construction wells. The results show that fuzzy-ball fluid is a water plugging material suitable for water control fracturing in tight gas wells, and its water control mechanism can also provide a new idea for the development of water control fracturing materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coal%20seam" title="coal seam">coal seam</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20layer" title=" deep layer"> deep layer</a>, <a href="https://publications.waset.org/abstracts/search?q=fracking" title=" fracking"> fracking</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy-ball%20fluid" title=" fuzzy-ball fluid"> fuzzy-ball fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20reconstruction" title=" reservoir reconstruction"> reservoir reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/137940/water-controlled-fracturing-with-fuzzy-ball-fluid-in-tight-gas-reservoirs-of-deep-coal-measures-in-sulige" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137940.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">227</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">1056</span> Investigating the Effects of Hydrogen on Wet Cement for Underground Hydrogen Storage Applications in Oil and Gas Wells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamoud%20Al-Hadrami">Hamoud Al-Hadrami</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Emadi"> Hossein Emadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Athar%20Hussain"> Athar Hussain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green hydrogen is quickly emerging as a new source of renewable energy for the world. Hydrogen production using water electrolysis is deemed as an environmentally friendly and safe source of energy for transportation and other industries. However, storing a high volume of hydrogen seems to be a significant challenge. Abandoned hydrocarbon reservoirs are considered as viable hydrogen storage options because of the availability of the required infrastructure such as wells and surface facilities. However, long-term wellbore integrity in these wells could be a serious challenge. Hydrogen reduces the compressive strength of a set cement if it gets in contact with the cement slurry. Also, mixing hydrogen with cement slurry slightly increases its density and rheological properties, which need to be considered to have a successful primary cementing operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title="hydrogen">hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20bore%20integrity" title=" well bore integrity"> well bore integrity</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20energy" title=" clean energy"> clean energy</a>, <a href="https://publications.waset.org/abstracts/search?q=cementing" title=" cementing"> cementing</a> </p> <a href="https://publications.waset.org/abstracts/142191/investigating-the-effects-of-hydrogen-on-wet-cement-for-underground-hydrogen-storage-applications-in-oil-and-gas-wells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142191.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">213</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">1055</span> Gas Lift Optimization Using Smart Gas Lift Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A.%20G.%20H.%20Abdalsadig">Mohamed A.

Presently, petroleum industry is investing in exploration and development fields in offshore locations where oil and gas wells are being drilled thousands of feet below the ocean in high pressure and temperature conditions. Therefore, gas-lifted oil wells are capable of failure through gas lift valves which are considered as the heart of the gas lift system for controlling the amount of the gas inside the tubing string. The gas injection rate through gas lift valve must be controlled to be sufficient to obtain and maintain critical flow, also, gas lift valves must be designed not only to allow gas passage through it and prevent oil passage, but also for gas injection into wells to be started and stopped when needed. In this paper, smart gas lift valve has been used to investigate the effect of the valve port size, depth of injection and vertical lift performance on well productivity; all these aspects have been investigated using PROSPER simulator program coupled with experimental data. The results show that by using smart gas lift valve, the gas injection rate can be controlled which leads to improved flow performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Effect%20of%20gas%20lift%20valve%20port%20size" title="Effect of gas lift valve port size">Effect of gas lift valve port size</a>, <a href="https://publications.waset.org/abstracts/search?q=effect%20water%20cut" title=" effect water cut"> effect water cut</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20flow%20performance" title=" vertical flow performance"> vertical flow performance</a> </p> <a href="https://publications.waset.org/abstracts/48540/gas-lift-optimization-using-smart-gas-lift-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48540.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">291</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">1054</span> Numerical Study of Trailing Edge Serrations on a Wells Turbine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20S.%20AlKhalifa">Abdullah S.

The baseline turbine consists of eight blades with NACA 0015 airfoils. The blade chord length was 0.125 m, and the span was 0.100 m. Two modified NACA 0015 serrated configurations were studied: 1) full-span and 2) partial span serrations covering the trailing edge from hub to tip. Numerical simulations were carried out by solving the three-dimensional, incompressible steady-state Reynolds Averaged Navier-Stokes (RANS) equations using the k-ω SST turbulence model in ANSYS™ (CFX). The aerodynamic performance of the modified Wells turbine to the baseline was made by comparing non-dimensional parameters of torque coefficient, pressure drop coefficient, and turbine efficiency. A comparison of the surface limiting streamlines was performed to analyze the flow topology of the turbine blades. The trailing edge serrations generated a substantial change in surface pressure and effectively reduced the separated flow region, thus improving efficiency in most cases. As a result, the average efficiency increased across the range of simulated flow coefficients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title="renewable energy">renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=trailing%20edge%20serrations" title=" trailing edge serrations"> trailing edge serrations</a>, <a href="https://publications.waset.org/abstracts/search?q=Wells%20turbine" title=" Wells turbine"> Wells turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20serration" title=" partial serration"> partial serration</a> </p> <a href="https://publications.waset.org/abstracts/157691/numerical-study-of-trailing-edge-serrations-on-a-wells-turbine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157691.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">101</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">1053</span> Gabriel Mtsire’s "The Golden Spring" and Its Primary Sources, Textual and Content Changes Based on Cultural Development in the Context of the 4th-20th Centuries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Georgi%20Kalandadze">Georgi Kalandadze</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For studying the development of world civilizations, textual sources that have undergone textological and worldview changes are of great importance. The conference will discuss the collection of the XVIII century "The Golden Spring", compiled by Gabriel Mtsire, which includes texts of John Chrysostom. John Chrysostom lived in the 4th century and his writings correspond to the culture of readers of that time. In the 10th-11th centuries, the works of John Chrysostom were translated into Georgian by Euthymius of Athos. These texts correspond to the requirements of the Georgian society of the 10th-11th centuries. In the 18th century, Gabriel Mtsire collected and edited these texts to make them more understandable to his modern readers. In the 20th century, these texts were again adapted. Thus, the present study provides an opportunity to evaluate and outline the linguistic and content transformation process of the same work over 16 centuries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gabriel%20mtsire" title="gabriel mtsire">gabriel mtsire</a>, <a href="https://publications.waset.org/abstracts/search?q=john%20chrysostom" title=" john chrysostom"> john chrysostom</a>, <a href="https://publications.waset.org/abstracts/search?q=euthymius%20the%20athonite" title=" euthymius the athonite"> euthymius the athonite</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20golden%20spring" title=" the golden spring"> the golden spring</a> </p> <a href="https://publications.waset.org/abstracts/166769/gabriel-mtsires-the-golden-spring-and-its-primary-sources-textual-and-content-changes-based-on-cultural-development-in-the-context-of-the-4th-20th-centuries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166769.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">85</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">1052</span> The Effect of Finding and Development Costs and Gas Price on Basins in the Barnett Shale</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Kenomore">Michael Kenomore</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hassan"> Mohamed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Shah"> Amjad Shah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hom%20Dhakal"> Hom Dhakal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shale gas reservoirs have been of greater importance compared to shale oil reservoirs since 2009 and with the current nature of the oil market, understanding the technical and economic performance of shale gas reservoirs is of importance. Using the Barnett shale as a case study, an economic model was developed to quantify the effect of finding and development costs and gas prices on the basins in the Barnett shale using net present value as an evaluation parameter. A rate of return of 20% and a payback period of 60 months or less was used as the investment hurdle in the model. The Barnett was split into four basins (Strawn Basin, Ouachita Folded Belt, Forth-worth Syncline and Bend-arch Basin) with analysis conducted on each of the basin to provide a holistic outlook. The dataset consisted of only horizontal wells that started production from 2008 to at most 2015 with 1835 wells coming from the strawn basin, 137 wells from the Ouachita folded belt, 55 wells from the bend-arch basin and 724 wells from the forth-worth syncline. The data was analyzed initially on Microsoft Excel to determine the estimated ultimate recoverable (EUR). The range of EUR from each basin were loaded in the Palisade Risk software and a log normal distribution typical of Barnett shale wells was fitted to the dataset. Monte Carlo simulation was then carried out over a 1000 iterations to obtain a cumulative distribution plot showing the probabilistic distribution of EUR for each basin. From the cumulative distribution plot, the P10, P50 and P90 EUR values for each basin were used in the economic model. Gas production from an individual well with a EUR similar to the calculated EUR was chosen and rescaled to fit the calculated EUR values for each basin at the respective percentiles i.e. P10, P50 and P90. The rescaled production was entered into the economic model to determine the effect of the finding and development cost and gas price on the net present value (10% discount rate/year) as well as also determine the scenario that satisfied the proposed investment hurdle. The finding and development costs used in this paper (assumed to consist only of the drilling and completion costs) were £1 million, £2 million and £4 million while the gas price was varied from $2/MCF-$13/MCF based on Henry Hub spot prices from 2008-2015. One of the major findings in this study was that wells in the bend-arch basin were least economic, higher gas prices are needed in basins containing non-core counties and 90% of the Barnet shale wells were not economic at all finding and development costs irrespective of the gas price in all the basins. This study helps to determine the percentage of wells that are economic at different range of costs and gas prices, determine the basins that are most economic and the wells that satisfy the investment hurdle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shale%20gas" title="shale gas">shale gas</a>, <a href="https://publications.waset.org/abstracts/search?q=Barnett%20shale" title=" Barnett shale"> Barnett shale</a>, <a href="https://publications.waset.org/abstracts/search?q=unconventional%20gas" title=" unconventional gas"> unconventional gas</a>, <a href="https://publications.waset.org/abstracts/search?q=estimated%20ultimate%20recoverable" title=" estimated ultimate recoverable"> estimated ultimate recoverable</a> </p> <a href="https://publications.waset.org/abstracts/66971/the-effect-of-finding-and-development-costs-and-gas-price-on-basins-in-the-barnett-shale" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66971.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1051</span> Diagnostic Yield of CT PA and Value of Pre Test Assessments in Predicting the Probability of Pulmonary Embolism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shanza%20Akram">Shanza Akram</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameen%20Toor"> Sameen Toor</a>, <a href="https://publications.waset.org/abstracts/search?q=Heba%20Harb%20Abu%20Alkass"> Heba Harb Abu Alkass</a>, <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Abdulsalam%20Altaha"> Zainab Abdulsalam Altaha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Taha%20Abdulla"> Sara Taha Abdulla</a>, <a href="https://publications.waset.org/abstracts/search?q=Saleem%20Imran"> Saleem Imran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Acute pulmonary embolism (PE) is a common disease and can be fatal. The clinical presentation is variable and nonspecific, making accurate diagnosis difficult. Testing patients with suspected acute PE has increased dramatically. However, the overuse of some tests, particularly CT and D-dimer measurement, may not improve care while potentially leading to patient harm and unnecessary expense. CTPA is the investigation of choice for PE. Its easy availability, accuracy and ability to provide alternative diagnosis has lowered the threshold for performing it, resulting in its overuse. Guidelines have recommended the use of clinical pretest probability tools such as ‘Wells score’ to assess risk of suspected PE. Unfortunately, implementation of guidelines in clinical practice is inconsistent. This has led to low risk patients being subjected to unnecessary imaging, exposure to radiation and possible contrast related complications. Aim: To study the diagnostic yield of CT PA, clinical pretest probability of patients according to wells score and to determine whether or not there was an overuse of CTPA in our service. Methods: CT scans done on patients with suspected P.E in our hospital from 1st January 2014 to 31st December 2014 were retrospectively reviewed. Medical records were reviewed to study demographics, clinical presentation, final diagnosis, and to establish if Wells score and D-Dimer were used correctly in predicting the probability of PE and the need for subsequent CTPA. Results: 100 patients (51male) underwent CT PA in the time period. Mean age was 57 years (24-91 years). Majority of patients presented with shortness of breath (52%). Other presenting symptoms included chest pain 34%, palpitations 6%, collapse 5% and haemoptysis 5%. D Dimer test was done in 69%. Overall Wells score was low (<2) in 28 %, moderate (>2 - < 6) in 47% and high (> 6) in 15% of patients. Wells score was documented in medical notes of only 20% patients. PE was confirmed in 12% (8 male) patients. 4 had bilateral PE’s. In high-risk group (Wells > 6) (n=15), there were 5 diagnosed PEs. In moderate risk group (Wells >2 - < 6) (n=47), there were 6 and in low risk group (Wells <2) (n=28), one case of PE was confirmed. CT scans negative for PE showed pleural effusion in 30, Consolidation in 20, atelactasis in 15 and pulmonary nodule in 4 patients. 31 scans were completely normal. Conclusion: Yield of CT for pulmonary embolism was low in our cohort at 12%. A significant number of our patients who underwent CT PA had low Wells score. This suggests that CT PA is over utilized in our institution. Wells score was poorly documented in medical notes. CT-PA was able to detect alternative pulmonary abnormalities explaining the patient's clinical presentation. CT-PA requires concomitant pretest clinical probability assessment to be an effective diagnostic tool for confirming or excluding PE. . Clinicians should use validated clinical prediction rules to estimate pretest probability in patients in whom acute PE is being considered. Combining Wells scores with clinical and laboratory assessment may reduce the need for CTPA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CT%20PA" title="CT PA">CT PA</a>, <a href="https://publications.waset.org/abstracts/search?q=D%20dimer" title=" D dimer"> D dimer</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary%20embolism" title=" pulmonary embolism"> pulmonary embolism</a>, <a href="https://publications.waset.org/abstracts/search?q=wells%20score" title=" wells score"> wells score</a> </p> <a href="https://publications.waset.org/abstracts/41853/diagnostic-yield-of-ct-pa-and-value-of-pre-test-assessments-in-predicting-the-probability-of-pulmonary-embolism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41853.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">231</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">1050</span> When Talk Is the Cure for the Morning After: Talking Therapy in Conor Mcpherson’s Dublin Carol and Shining City</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Hamoud%20Alatawi">Maha Hamoud Alatawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drawing on the work of John McLeod and Ariel Watson, this paper explains the relationship between narrative and psychotherapy in two plays by the Irish playwright Conor McPherson.

In the present study, simulation optimization approach has been used to develop management strategy for remediating LNAPL (Light Non-Aqueous Phase Liquid) contaminated aquifers. Benzene, toluene, ethyl benzene and xylene are the main component of LNAPL contaminant. Collectively, these contaminants are known as BTEX. In in-situ bioremediation process, a set of injection and extraction wells are installed. Injection wells supply oxygen and other nutrient which convert BTEX into carbon dioxide and water with the help of indigenous soil bacteria. On the other hand, extraction wells check the movement of plume along downstream. In this study, optimal design of the system has been done using PSO (Particle Swarm Optimization) algorithm. A comprehensive management strategy for pumping of injection and extraction wells has been done to attain a maximum allowable concentration of 5 ppm and 4.5 ppm. The management strategy comprises determination of pumping rates, the total pumping volume and the total running cost incurred for each potential injection and extraction well. The results indicate a high pumping rate for injection wells during the initial management period since it facilitates the availability of oxygen and other nutrients necessary for biodegradation, however it is low during the third year on account of sufficient oxygen availability. This is because the contaminant is assumed to have biodegraded by the end of the third year when the concentration drops to a permissible level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater" title="groundwater">groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=in-situ%20bioremediation" title=" in-situ bioremediation"> in-situ bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20non-aqueous%20phase%20liquid" title=" light non-aqueous phase liquid"> light non-aqueous phase liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=BTEX" title=" BTEX"> BTEX</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a> </p> <a href="https://publications.waset.org/abstracts/39609/multi-criteria-optimal-management-strategy-for-in-situ-bioremediation-of-lnapl-contaminated-aquifer-using-particle-swarm-optimization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39609.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">445</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1048</span> Improving Recovery Reuse and Irrigation Scheme Efficiency – North Gaza Emergency Sewage Treatment Project as Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaser%20S.%20Kishawi">Yaser S.

The coastal aquifer is only source of water with only 5-10% suitable for human use. This barely cover the domestic and agricultural needs of Gaza Strip. Palestinian Water Authority Strategy is finding non-conventional water resource from treated wastewater to cover agricultural requirements and serve the population. A new WWTP project is to replace the old-overloaded Biet Lahia WWTP. The project consists of three parts; phase A (pressure line & infiltration basins - IBs), phase B (a new WWTP) and phase C (Recovery and Reuse Scheme – RRS – to capture the spreading plume). Currently, only phase A is functioning. Nearly 23 Mm3 of partially treated wastewater were infiltrated into the aquifer. Phase B and phase C witnessed many delays and this forced a reassessment of the RRS original design. An Environmental Management Plan was conducted from Jul 2013 to Jun 2014 on 13 existing monitoring wells surrounding the project location. This is to measure the efficiency of the SAT system and the spread of the contamination plume with relation to the efficiency of the proposed RRS. Along with the proposed location of the 27 recovery wells as part of the proposed RRS. The results of monitored wells were assessed compared with PWA baseline data. This was put into a groundwater model to simulate the plume to propose the best suitable solution to the delays. The redesign mainly manipulated the pumping rate of wells, proposed locations and functioning schedules (including wells groupings). The proposed simulations were examined using visual MODFLOW V4.2 to simulate the results. The results of monitored wells were assessed based on the location of the monitoring wells related to the proposed recovery wells locations (200m, 500m and 750m away from the IBs). Near the 500m line (the first row of proposed recovery wells), an increase of nitrate (from 30 to 70mg/L) compare to a decrease in Chloride (1500 to below 900mg/L) was found during the monitoring period which indicated an expansion of plume to this distance. On this rate with the required time to construct the recovery scheme, keeping the original design the RRS will fail to capture the plume. Based on that many simulations were conducted leading into three main scenarios. The scenarios manipulated the starting dates, the pumping rate and the locations of recovery wells. A simulation of plume expansion and path-lines were extracted from the model monitoring how to prevent the expansion towards the nearby municipal wells. It was concluded that the location is the most important factor in determining the RRS efficiency. Scenario III was adopted and showed an effective results even with a reduced pumping rates. This scenario proposed adding two additional recovery wells in a location beyond the 750m line to compensate the delays and effectively capture the plume. A continuous monitoring program for current and future monitoring wells should be in place to support the proposed scenario and ensure maximum protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20aquifer%20treatment" title="soil aquifer treatment">soil aquifer treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20and%20reuse%20scheme" title=" recovery and reuse scheme"> recovery and reuse scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration%20basins" title=" infiltration basins"> infiltration basins</a>, <a href="https://publications.waset.org/abstracts/search?q=north%20gaza" title=" north gaza"> north gaza</a> </p> <a href="https://publications.waset.org/abstracts/27630/improving-recovery-reuse-and-irrigation-scheme-efficiency-north-gaza-emergency-sewage-treatment-project-as-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27630.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">313</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">1047</span> An East-West Trans-Cultural Study: Zen Enlightenment in Asian and John Cage's Visual Arts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu-Shun%20Elisa%20Pong">Yu-Shun Elisa Pong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> American composer John Cage (1912-1992) is an influential figure in musical, visual and performing arts after World War II and has also been claimed as a forerunner of the western avant-garde in the artistic field. However, the crucial factors contributed to his highly acclaimed achievements include the Zen enlightenment, which he mainly got from Japanese Zen master D. T. Suzuki (1870-1966). As a kind of reflection and afterthought of the Zen inspiration, John Cage created various forms of arts in which visual arts have recently attracted more and more attention and discussion, especially from the perspectives of Zen. John Cage had started to create visual art works since he was 66 years old and the activity had lasted until his death. The quality and quantity of the works are worthy of in-depth study— the 667 pieces of print, 114 pieces of water color, and about 150 pieces of sketch. Cage’s stylistic changes during the 14 years of creation are quite obvious, and the Zen elements in the later works seem to be omnipresent. Based on comparative artistic study, a historical and conceptual view of Zen art that was formed initially in the traditional Chinese and Japanese visual arts will be discussed. Then, Chinese and Japanese representative Zen works will be mentioned, and the technique aspect, as well as stylistic analysis, will be revealed. Finally, a comprehensive comparison of the original Oriental Zen works with John Cage’s works and focus on the influence, and art transformation will be addressed. The master pieces from Zen tradition by Chinese artists like Liang Kai (d. 1210) and Ma Yuan (1160-1225) from Southern Sung Dynasty, the Japanese artists like Sesshū (1420-1506), Miyamoto Musashi (1584-1645) and some others would be discussed. In the current study, these art works from different periods of historical development in Zen will serve as the basis of analogy, interpretation, and criticism to Cage's visual art works. Through the perspectives of the Zen authenticity from Asia, we see how John Cage appropriated the eastern culture to his innovation, which changed the art world forever. And it is believed that through a transition from inter-, cross-, toward trans-cultural inspiration, John Cage set up a unique pathway of art innovations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Cage" title="John Cage">John Cage</a>, <a href="https://publications.waset.org/abstracts/search?q=Chinese%20Zen%20art" title=" Chinese Zen art"> Chinese Zen art</a>, <a href="https://publications.waset.org/abstracts/search?q=Japanese%20Zen%20art" title=" Japanese Zen art"> Japanese Zen art</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20art" title=" visual art"> visual art</a> </p> <a href="https://publications.waset.org/abstracts/78742/an-east-west-trans-cultural-study-zen-enlightenment-in-asian-and-john-cages-visual-arts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78742.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">524</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">1046</span> The Assessment of Infiltrated Wastewater on the Efficiency of Recovery Reuse and Irrigation Scheme: North Gaza Emergency Sewage Treatment Project as a Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yaser%20S.%20Kishawi">Yaser S.

The coastal aquifer is only source of water with only 5-10% suitable for human use. This barely covers the domestic and agricultural needs of Gaza Strip. Palestinian Water Authority Strategy is finding non-conventional water resource from treated wastewater to cover agricultural requirements and serve the population. A new WWTP project is to replace the old-overloaded Biet Lahia WWTP. The project consists of three parts; phase A (pressure line and infiltration basins-IBs), phase B (a new WWTP) and phase C (Recovery and Reuse Scheme–RRS– to capture the spreading plume). Currently, only phase A is functioning. Nearly 23 Mm3 of partially treated wastewater were infiltrated into the aquifer. Phase B and phase C witnessed many delays and this forced a reassessment of the RRS original design. An Environmental Management Plan was conducted from Jul 2013 to Jun 2014 on 13 existing monitoring wells surrounding the project location. This is to measure the efficiency of the SAT system and the spread of the contamination plume with relation to the efficiency of the proposed RRS. Along with the proposed location of the 27 recovery wells as part of the proposed RRS. The results of monitored wells were assessed compared with PWA baseline data. This was put into a groundwater model to simulate the plume to propose the best suitable solution to the delays. The redesign mainly manipulated the pumping rate of wells, proposed locations and functioning schedules (including wells groupings). The proposed simulations were examined using visual MODFLOW V4.2 to simulate the results. The results of monitored wells were assessed based on the location of the monitoring wells related to the proposed recovery wells locations (200m, 500m, and 750m away from the IBs). Near the 500m line (the first row of proposed recovery wells), an increase of nitrate (from 30 to 70mg/L) compare to a decrease in Chloride (1500 to below 900mg/L) was found during the monitoring period which indicated an expansion of plume to this distance. On this rate with the required time to construct the recovery scheme, keeping the original design the RRS will fail to capture the plume. Based on that many simulations were conducted leading into three main scenarios. The scenarios manipulated the starting dates, the pumping rate and the locations of recovery wells. A simulation of plume expansion and path-lines were extracted from the model monitoring how to prevent the expansion towards the nearby municipal wells. It was concluded that the location is the most important factor in determining the RRS efficiency. Scenario III was adopted and showed effective results even with a reduced pumping rates. This scenario proposed adding two additional recovery wells in a location beyond the 750m line to compensate the delays and effectively capture the plume. A continuous monitoring program for current and future monitoring wells should be in place to support the proposed scenario and ensure maximum protection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20aquifer%20treatment" title="soil aquifer treatment">soil aquifer treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=recovery%20reuse%20scheme" title=" recovery reuse scheme"> recovery reuse scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration%20basins" title=" infiltration basins"> infiltration basins</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Gaza" title=" North Gaza"> North Gaza</a> </p> <a href="https://publications.waset.org/abstracts/21235/the-assessment-of-infiltrated-wastewater-on-the-efficiency-of-recovery-reuse-and-irrigation-scheme-north-gaza-emergency-sewage-treatment-project-as-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21235.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">204</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">1045</span> Aerodynamic Devices Development for Model Aircraft Control and Wind-Driven Bicycle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuta%20Moriyama">Yuta Moriyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsuyoshi%20Yamazaki"> Tsuyoshi Yamazaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Etsuo%20Morishita"> Etsuo Morishita</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Several aerodynamic devices currently attract engineers and research students. The plasma actuator is one of them, and it is very effective to control the flow. The actuator recovers a separated flow to an attached one. The actuator is also inversely applied to a spoiler. The model aircraft might be controlled by this actuator. We develop a model aircraft with the plasma actuator. Another interesting device is the Wells turbine which rotates in one direction. The present authors propose a bicycle with the Wells turbine in the wheels. Power reduction is measured when the turbine is driven by an electric motor at the exit of a wind tunnel. Several Watts power reduction might be possible. This means that the torque of the bike can be augmented by the turbine in the cross wind. These devices are tested in the wind tunnel with a three-component balance and the aerodynamic forces and moment are obtained. In this paper, we introduce these devices and their aerodynamic characteristics. The control force and moment of the plasma actuator are clarified and the power reduction of the bicycle is quantified. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20aircraft" title=" model aircraft"> model aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20actuator" title=" plasma actuator"> plasma actuator</a>, <a href="https://publications.waset.org/abstracts/search?q=Wells%20turbine" title=" Wells turbine"> Wells turbine</a> </p> <a href="https://publications.waset.org/abstracts/92167/aerodynamic-devices-development-for-model-aircraft-control-and-wind-driven-bicycle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92167.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">246</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">1044</span> Investigation the Polluting Effect of Heavy Elements on Underground Water in Behbahan Plain, South West Zagros</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohreh%20Marbooti">Zohreh Marbooti</a>, <a href="https://publications.waset.org/abstracts/search?q=Rezvan%20Khavari"> Rezvan Khavari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater as an essential part of natural resources seems to be an important issue in environmental engineering, so preservation and purification of it can have a critical value for any community. This paper investigates the concentration of elements of Pb, Cd, As, Se. For ground water in Behbahan (a city on south west of Iran), to this purpose a group of 30 wells were studied to examine the concentration of the elements of Pb, Cd, As, Se, and also to determine PH, EC, TDS, temperature and the ions of HCO32-, SO42-, Cl-, Na+, Mg2+, Ca2+, K+ for the wells. Results of the analyses show that the concentration of the elements of Pb, As and, Cd in 33,13,56 percent of the wells respectively and Se in all the samples were greater than normal range of WHO. Since there is a low correlation between Pb and major ions of (HCO32-, SO42-, Cl-, Na+, Mg2+, Ca2+, K+) it can be revealed that Pb overconcentration caused by human contamination. Relative great correlation between Se and the ions showed that Se derived from Gypsum and Dolomit. The big correlation between As and major cations and onions, imply that As can originate from dissolution and liquidation of mineral evaporation in the zone. The high rate of Cadmium concentration in urban sewagewater is due to the small industries, workshops and, mills wastewater. <p class="card-text"><strong>Keywords:</strong> <a
