Tuberculosis (TB) is considered as a major disease that affects daily activities and impairs health-related quality of life (HRQoL). The impact of TB on HRQoL can affect treatment outcome and may lead to treatment defaulting. Therefore, this study aims to evaluate the HRQoL of TB treatment lost to follow-up during and after treatment in Yemen. For this aim, this prospective study enrolled a total of 399 TB lost to follow-up patients between January 2011 and December 2015. By applying HRQoL criteria, only 136 fill the survey during treatment. Moreover, 96 were traced and fill out the HRQoL survey. All eight HRQol domains were categorized into the physical component score (PCS) and mental component score (MCS), which were calculated using QM scoring software. Results show that all lost to follow-up TB patients reported a score less than 47 for all eight domains, except general health (67.3) during their treatment period. Low scores of 27.9 and 29.8 were reported for emotional role limitation (RE) and mental health (MH), respectively. Moreover, the mental component score (MCS) was found to be only 28.9. The trace lost follow-up shows a significant improvement in all eight domains and a mental component score of 43.1. The low scores of 27.9 and 29.8 for role emotion and mental health, respectively, in addition to the MCS score of 28.9, show that severe emotional condition and reflect the higher depression during treatment period that can result to lost to follow-up. The low MH, RE, and MCS can be used as a clue for predicting future TB treatment lost to follow-up. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yemen" title="Yemen">Yemen</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberculosis" title=" tuberculosis"> tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=health-related%20quality%20of%20life" title=" health-related quality of life"> health-related quality of life</a>, <a href="https://publications.waset.org/abstracts/search?q=Khat" title=" Khat"> Khat</a> </p> <a href="https://publications.waset.org/abstracts/102697/evaluating-health-related-quality-of-life-of-lost-to-follow-up-tuberculosis-patients-in-yemen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102697.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">173</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">352</span> Design, Research and Culture Change in the Age of Transformation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maya%20Jaber">Maya Jaber</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change is one of the biggest challenges that require immediate attention and mitigation for the continued prosperity of human existence.

Change agents and leaders will need a new paradigm of thinking for creative problem solving and innovation in a time of uncertainty. A new framework that is developed from Design Science Research foundations with holistic design thinking methodologies (HTDM) and action research approaches has been developed through Dr. Jaber’s research. It combines these philosophies into a three-step process that can be utilized in practice for any sustainability, change, or project management applications. This framework was developed to assist in the pedagogy for the implementation of her holistic strategy formalized framework Integral Design Thinking (IDT). Her work focuses on real world application for the streamlining and adoption of initiatives into organizational culture transformation. This paper will discuss the foundations of this philosophy and the methods for utilization in practice developed in Dr. Jaber's research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20science%20research" title="design science research">design science research</a>, <a href="https://publications.waset.org/abstracts/search?q=action%20research" title=" action research"> action research</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20thinking" title=" critical thinking"> critical thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20thinking" title=" design thinking"> design thinking</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20transformation" title=" organizational transformation"> organizational transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability%20management" title=" sustainability management"> sustainability management</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20culture%20change" title=" organizational culture change"> organizational culture change</a> </p> <a href="https://publications.waset.org/abstracts/143518/bringing-design-science-research-methodology-into-real-world-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143518.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">350</span> Isolation and Molecular Identification of Two Fungal Strains Capable of Degrading hydrocarbon Contaminants on Saudi Arabian Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20A.%20EL%20Hanafy">Amr A.

On the basis of aptitude to degrade the crude oil and DCPIP assay, two fungal isolates were selected amongst 15 oil degrading strains. Analysis of ITS-1, ITS-2 and amplicon pyrosequencing studies of fungal diversity revealed that these strains belong to Penicillium and Aspergillus species. Two strains that proved to be the most efficient in degrading crude oil was Aspergillus niger (54 %) and Penicillium commune (48 %) Subsequent to two weeks of cultivation in BHS medium the degradation rate were recorded by using spectrophotometer and GC-MS. Hence, it is cleared that these fungal strains has the capability of degradation and can be utilized for cleaning the Saudi Arabian environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungal%20%20strains" title="fungal strains">fungal strains</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20contaminants" title=" hydrocarbon contaminants"> hydrocarbon contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20identification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradation" title=" biodegradation"> biodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/36036/isolation-and-molecular-identification-of-two-fungal-strains-capable-of-degrading-hydrocarbon-contaminants-on-saudi-arabian-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36036.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">522</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">349</span> Double-Diffusive Natural Convection with Various Partially Heated and Salted Sources Arrangements in an Open Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Norazam%20Arbin">Norazam Arbin</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibis%20Saleh"> Habibis Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Alsabery"> Ammar Alsabery</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishak%20Hashim"> Ishak Hashim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Double-diffusive natural convection in an open top cavity with partial vertical heating and salting sources is investigated numerically. Different temperatures and concentrations are applied at the source location on the right and left walls while the other remains adiabatic except at the open top surface. Various combinations of sources arrangements are imposed at the vertical walls in order to observe the signiﬁcant impact to the convection. An iterative ﬁnite different method is used to solve the dimensionless governing equations. The effects of Marangoni number and sources arrangements on the contours of streamlines, isotherms, and concentrations are visualized as the outcome of the numerical solutions. The average Nusselt and Sherwood number are presented for various sources arrangements. It is clearly observed that the sources arrangements gave major impact on the heat and mass transfer rates. A horizontal-like pattern is found for sources arrangements that near the top-free surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=double-diffusive" title="double-diffusive">double-diffusive</a>, <a href="https://publications.waset.org/abstracts/search?q=Marangoni%20effect" title=" Marangoni effect"> Marangoni effect</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20heating" title=" partial heating"> partial heating</a>, <a href="https://publications.waset.org/abstracts/search?q=salting" title=" salting"> salting</a> </p> <a href="https://publications.waset.org/abstracts/13496/double-diffusive-natural-convection-with-various-partially-heated-and-salted-sources-arrangements-in-an-open-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13496.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">348</span> Unsteady Natural Convection in a Square Cavity Partially Filled with Porous Media Using a Thermal Non-Equilibrium Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Alsabery">Ammar Alsabery</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibis%20Saleh"> Habibis Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Norazam%20Arbin"> Norazam Arbin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishak%20Hashim"> Ishak Hashim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unsteady natural convection and heat transfer in a square cavity partially filled with porous media using a thermal non-equilibrium model is studied in this paper. The left vertical wall is maintained at a constant hot temperature and the right vertical wall is maintained at a constant cold temperature, while the horizontal walls are adiabatic. The governing equations are obtained by applying the Darcy model and Boussinesq approximation. COMSOL's finite element method is used to solve the non-dimensional governing equations together with specified boundary conditions. The governing parameters of this study are the Rayleigh number, the modified thermal conductivity ratio, the inter-phase heat transfer coefficien and the time independent. The results presented for values of the governing parameters in terms of streamlines in both fluid/porous layer, isotherms of fluid and solid porous layer, isotherms of fluid layer, and average Nusselt number. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unsteady%20natural%20convection" title="unsteady natural convection">unsteady natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20non-equilibrium%20model" title=" thermal non-equilibrium model"> thermal non-equilibrium model</a>, <a href="https://publications.waset.org/abstracts/search?q=Darcy%20model" title=" Darcy model"> Darcy model</a> </p> <a href="https://publications.waset.org/abstracts/12724/unsteady-natural-convection-in-a-square-cavity-partially-filled-with-porous-media-using-a-thermal-non-equilibrium-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12724.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">376</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">347</span> Optimization of Robot Motion Planning Using Biogeography Based Optimization (Bbo)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaber%20Nikpouri">Jaber Nikpouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Arsalan%20Amralizadeh"> Arsalan Amralizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In robotics manipulators, the trajectory should be optimum, thus the torque of the robot can be minimized in order to save power.

Unfortunately, when the voltage of the S.C supplying the inverter reaches the minimal threshold of 7-8VDC the inverter shuts down leaving the remaining 40% of the valuable energy stored inside the ultracapacitor un-usable. In this work a power electronic circuit is proposed which switches 2 banks of supercapacitors from parallel connection when both are fully charged at 14VDC to serial connection when their voltages drop down to 7 volts, thus keeping the inverter working within its operating limits for a longer time and advantageously tapping almost 92% of the stored energy in the supercapacitors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra%20capacitor" title="ultra capacitor">ultra capacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=switched%20ultracapacitors" title=" switched ultracapacitors"> switched ultracapacitors</a>, <a href="https://publications.waset.org/abstracts/search?q=inverter" title=" inverter"> inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=supercapacitor" title=" supercapacitor"> supercapacitor</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20connection" title=" parallel connection"> parallel connection</a>, <a href="https://publications.waset.org/abstracts/search?q=serial%20connection" title=" serial connection"> serial connection</a>, <a href="https://publications.waset.org/abstracts/search?q=battery%20limitation" title=" battery limitation"> battery limitation</a> </p> <a href="https://publications.waset.org/abstracts/12182/switched-ultracapacitors-for-maximizing-energy-supply" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12182.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">411</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">344</span> Mechanized Harvest Impact on Reproductive Performance of Ewes of Some Villages</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaber%20Jafarzadeh">Jaber Jafarzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The two nodes of treatment for the study of indirect effects on the reproductive performance of sheep farming machines used.

The traditional Waterfall approach used to develop software systems requires a lot of time to estimate the effort needed to implement user requirements. Agile manifesto, however, is currently more used in the industry than the Waterfall to develop software systems. In Agile, the user requirement is referred to as a user story. Agile teams mostly use the Fibonacci sequence 1, 2, 3, 5, 8, 11, etc. in estimating the effort needed to implement the user story. This work shows through analysis that the Arithmetic sequence, e.g., 3, 6, 9, 12, etc., is more effective than the Fibonacci sequence in estimating the user stories. This paper mathematically and visually proves the effectiveness of the Arithmetic sequence over the FB sequence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agie" title="agie">agie</a>, <a href="https://publications.waset.org/abstracts/search?q=scrum" title=" scrum"> scrum</a>, <a href="https://publications.waset.org/abstracts/search?q=estimation" title=" estimation"> estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=fibonacci%20sequence" title=" fibonacci sequence"> fibonacci sequence</a> </p> <a href="https://publications.waset.org/abstracts/145354/in-agile-projects-arithmetic-sequence-is-more-effective-than-fibonacci-sequence-to-use-for-estimating-the-implementation-effort-of-user-stories" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145354.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">205</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">341</span> Failure Detection in an Edge Cracked Tapered Pipe Conveying Fluid Using Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Gaith">Mohamed Gaith</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaid%20Haddadin"> Zaid Haddadin</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulah%20Wahbe"> Abdulah Wahbe</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Hamam"> Mahmoud Hamam</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Qunees"> Mahmoud Qunees</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Al%20Khatib"> Mohammad Al Khatib</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Bsaileh"> Mohammad Bsaileh</a>, <a href="https://publications.waset.org/abstracts/search?q=Abd%20Al-Aziz%20Jaber"> Abd Al-Aziz Jaber</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Aqra%E2%80%99a"> Ahmad Aqra’a</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The crack is one of the most common types of failure in pipelines that convey fluid, and early detection of the crack may assist to avoid the piping system from experiencing catastrophic damage, which would otherwise be fatal.

In addition, RCA and RAP were incorporated in the same mixes with replacement levels of (1) 20% RCA and 80% RAP; (2) 40% RCA and 60% RAP; (3) 60% RCA and 40% RAP; and (4) 80% RCA and 20% RAP. A comparison between the experimental capacities and the theoretically predicted values according to Eurocode 4 (EC4) was made as well.

The results are given graphically by using the EES software, and an appropriate discussion and conclusion was made. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=exergy%20efficiency" title="exergy efficiency">exergy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title="gas turbine">gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=irreversibility" title=" irreversibility"> irreversibility</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerator" title=" regenerator"> regenerator</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20efficiency" title=" thermal efficiency"> thermal efficiency</a> </p> <a href="https://publications.waset.org/abstracts/68679/thermo-exergy-optimization-of-gas-turbine-cycle-with-two-different-regenerator-designs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">334</span> The Nursing Rounds System: Effect of Patient's Call Light Use, Bed Sores, Fall and Satisfaction Level</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassem%20Saleh">Bassem Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussam%20Nusair"> Hussam Nusair</a>, <a href="https://publications.waset.org/abstracts/search?q=Nariman%20Al%20Zubadi"> Nariman Al Zubadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shams%20Al%20Shloul"> Shams Al Shloul</a>, <a href="https://publications.waset.org/abstracts/search?q=Usama%20Saleh"> Usama Saleh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The nursing round system (NRS) means checking patients on an hourly basis during the A (0700–2200 h) shift and once every 2 h during the B (2200–0700 h) by the assigned nursing staff. The overall goal of this prospective study is to implement an NRS in a major rehabilitation centre—Sultan Bin Abdulaziz Humanitarian City—in the Riyadh area of the Kingdom of Saudi Arabia. The purposes of this study are to measure the effect of the NRS on: (i) the use of patient call light; (ii) the number of incidences of patients’ fall; (iii) the number of incidences of hospital-acquired bed sores; and (iv) the level of patients’ satisfaction. All patients hospitalized in the male stroke unit will be involved in this study. For the period of 8 weeks (17 December 2009–17 February 2010) All Nursing staff on the unit will record each call light and the patient’s need. Implementation of the NRS would start on 18 February 2010 and last for 8 weeks, until 18 April 2010. Data collected throughout this period will be compared with data collected during the 8 weeks period immediately preceding the implementation of the NRS (17 December 2009–17 February 2010) in order to measure the impact of the call light use. The following information were collected on all subjects involved in the study: (i) the Demographic Information Form; (ii) authors’ developed NRS Audit Form; (iii) Patient Call Light Audit Form; (iv) Patient Fall Audit Record; (v) Hospital-Acquired Bed Sores Audit Form; and (vi) hospital developed Patient Satisfaction Records. The findings suggested that a significant reduction on the use of call bell (P < 0.001), a significant reduction of fall incidence (P < 0.01) while pressure ulcer reduced by 50% before and after the implementation of NRS. In addition, the implementation of NRS increased patient satisfaction by 7/5 (P < 0.05). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=call%20light" title="call light">call light</a>, <a href="https://publications.waset.org/abstracts/search?q=patient-care%20management" title=" patient-care management"> patient-care management</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20safety" title=" patient safety"> patient safety</a>, <a href="https://publications.waset.org/abstracts/search?q=patient%20satisfaction" title=" patient satisfaction"> patient satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=rounds" title=" rounds"> rounds</a> </p> <a href="https://publications.waset.org/abstracts/41680/the-nursing-rounds-system-effect-of-patients-call-light-use-bed-sores-fall-and-satisfaction-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41680.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">374</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">333</span> Investigation of Main Operating Parameters Affecting Gas Turbine Efficiency and Gas Releases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhat%20Hajer">Farhat Hajer</a>, <a href="https://publications.waset.org/abstracts/search?q=Khir%20Tahar"> Khir Tahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Ben%20Brahim"> Ammar Ben Brahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents a study on the influence of the main operating variables on the gas turbine cycle.

More than 90% of esophageal cancers are either squamous cell carcinoma or adenocarcinoma. Squamous dysplasia is a precancerous lesion for squamous cell carcinoma and Barrett's esophagus is the precancerous lesion for adenocarcinoma. Gastro-esophageal reflux disease (GERD) is the initiation factor for Barrett's esophagus. Cyclooxygenase-2 (COX-2) is a key enzyme in arachidonic metabolism. It appears to play an important role in gastrointestinal carcinogenesis. COX-2 activity may be a potential target for the prevention of cancer progression by selective COX-2 inhibitors, which decrease proliferation and increase apoptosis. Objectives To assess COX-2 expression in premalignant and malignant esophageal epitheliums changes and detect its roles in progression of these lesions. Materials and Methods We analyzed the expression of COX-2 immunohistochemically in 40 esophageal biopsies utilizing the streptavidin-biotin-peroxidase complex method on archival formalin fixed-paraffin embedded blocks. Histopathologically, 17 (42.5%) of cases were non-malignant cases which included GERD, Barrett's esophagus and squamous dysplasia. The malignant cases were 23 (57.5%) squamous cell carcinoma, adenocarcinoma and undifferentiated carcinoma. Results In non-malignant cases 7 (41.2%) out of 17 cases had high COX-2 expression. In squamous cell carcinoma 10 (83.3%) out of 12 cases had high COX-2 expression. The expression of COX-2 was high in all 9 (100%) cases of adenocarcinoma. COX-2 expression is significantly increased (P=0.005 and P=0.0001) in squamous cell carcinoma and adenocarcinoma respectively. There was a significant difference in COX-2 immunoreactivity between malignant and non-malignant lesions (P=0.0003). Conclusion COX-2 is responsible for the progression of esophageal diseases from benign to malignant. We recommend that COX-2 immunohistochemistry should be done routinely for premalignant and malignant esophageal lesions as selective COX-2 inhibitors will be helpful in the treatment. Further studies on molecular and genetic basis of COX-2 expression are needed to unmask its role and relation to progression of esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cox-2" title="Cox-2">Cox-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20adinocarcinoma" title=" Esophageal adinocarcinoma"> Esophageal adinocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20squamous%20cell%20carcinoma" title=" Esophageal squamous cell carcinoma"> Esophageal squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunohistochemistry." title=" Immunohistochemistry.

The current study, therefore, evaluates the effectiveness of four various configurations for shear strengthening of deep beams with two different types of CFRP materials including sheets and laminates. For this purpose, a total of 10 specimens of deep beams were cast and tested. The shear performance of the strengthened beams is assessed with respect to the cracks’ formation, modes of failure, ultimate strength and the overall stiffness. The obtained results demonstrate the effectiveness of using the CFRP technique on enhancing the shear capacity of deep beams; however, the efficiency varies depending on the material used and the strengthening scheme adopted. Among the four investigated schemes, the highest increase in the ultimate strength is recorded by using the continuous wrap of two layers of CFRP sheets, exceeding a value of 86%, whereas an enhancement of about 36% is achieved by the inclined CFRP laminates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20beams" title="deep beams">deep beams</a>, <a href="https://publications.waset.org/abstracts/search?q=laminates" title=" laminates"> laminates</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20strengthening" title=" shear strengthening"> shear strengthening</a>, <a href="https://publications.waset.org/abstracts/search?q=sheets" title=" sheets"> sheets</a> </p> <a href="https://publications.waset.org/abstracts/55807/shear-strengthening-of-reinforced-concrete-deep-beams-using-carbon-fiber-reinforced-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55807.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">360</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">327</span> A Study of Recent Contribution on Simulation Tools for Network-on-Chip</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muthana%20Saleh%20Alalaki">Muthana Saleh Alalaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Opoku%20Agyeman"> Michael Opoku Agyeman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The growth in the number of Intellectual Properties (IPs) or the number of cores on the same chip becomes a critical issue in System-on-Chip (SoC) due to the intra-communication problem between the chip elements.

This paper studies to what extent the poet was committed to the Palestinian goals and agenda throughout poetry as well as to explore the ways and techniques in which the poet employed poetry in order to explore the Palestinian belonging and identification of the Palestinians in Israel. Methodologically, this paper will literary analyze some considerable poems of the poet looking in-depth critically and objectively. Moreover, this article relies on several poems of the poet because they are much relevant to the aimed discussion. By addressing both commitment and identity, this article hopes to contribute to a fuller understanding of Palestinian poets of 1960s to 2000s. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tawfiq%20Zayyad" title="Tawfiq Zayyad">Tawfiq Zayyad</a>, <a href="https://publications.waset.org/abstracts/search?q=Palestinian%20poetry" title=" Palestinian poetry"> Palestinian poetry</a>, <a href="https://publications.waset.org/abstracts/search?q=poetic%20commitment" title=" poetic commitment"> poetic commitment</a>, <a href="https://publications.waset.org/abstracts/search?q=poetic%20techniques" title=" poetic techniques"> poetic techniques</a> </p> <a href="https://publications.waset.org/abstracts/90126/the-quest-for-palestinian-identity-throughout-zayyads-poetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90126.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">163</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">324</span> Solar Seawater Desalination Still with Seawater Preheater Using Efficient Heat Transfer Oil: Numerical Investigation and Data Verification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20N.%20Shmroukh">Ahmed N.

This solar desalination unit with proposed auxiliary device as seawater preheating system using petrol based textherm oil was used to produce pure fresh water from seawater. The effective evaporation area of basin is about 1 m<sup>2</sup>. The unit was tested in two main operation modes which are normal and with seawater preheating system. The results showed that, there is good agreement between the theoretical data and the experimental data; this means that the numerical model can be accurately dependable for predicting the proposed solar still performance and design parameters. The results also showed that the fresh water productivity of the solar still in the modified preheating case which is higher than normal case, leads to an increase in productivity of 42%. <p
