The Helmholtz free energy function is introduced with the existence of a dissipation potential surface in the space of thermodynamic conjugate forces. The constitutive equation and the damage evolution were derived as well. The modified damage has been examined to model the nonlinear behavior of reinforced concrete (RC) slabs with an opening. A parametric study with RC was carried out to investigate the impact of different factors on the behavior of RC slabs. These factors are the opening area, the opening shape, the place of opening, and the thickness of the slabs. And the numerical results have been compared with the experimental data from literature. Finally, the model showed its ability to be applied to the structural analysis of RC slabs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damage%20mechanics" title="damage mechanics">damage mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=3-D%20numerical%20analysis" title=" 3-D numerical analysis"> 3-D numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=RC" title=" RC"> RC</a>, <a href="https://publications.waset.org/abstracts/search?q=slab%20with%20opening" title=" slab with opening"> slab with opening</a> </p> <a href="https://publications.waset.org/abstracts/97463/three-dimensional-numerical-investigation-for-reinforced-concrete-slabs-with-opening" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97463.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">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Innovative Approaches to Water Resources Management: Addressing Challenges through Machine Learning and Remote Sensing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Elsehsah">Abdelrahman Elsehsah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelazim%20Negm"> Abdelazim Negm</a>, <a href="https://publications.waset.org/abstracts/search?q=Eid%20Ashour"> Eid Ashour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elsahabi"> Mohamed Elsahabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water resources management is a critical field that encompasses the planning, development, conservation, and allocation of water resources to meet societal needs while ensuring environmental sustainability. This paper reviews the key concepts and challenges in water resources management, emphasizing the significance of a holistic approach that integrates social, economic, and environmental factors. Traditional water management practices, characterized by supply-oriented strategies and centralized control, are increasingly inadequate in addressing contemporary challenges such as water scarcity, climate change impacts, and ecosystem degradation. Emerging technologies, particularly machine learning and remote sensing, offer innovative solutions to enhance decision-making processes in water management. Machine learning algorithms facilitate accurate water demand forecasting, quality monitoring, and leak detection, while remote sensing technologies provide vital data for assessing water availability and quality. This review highlights the need for integrated water management strategies that leverage these technologies to promote sustainable practices and foster resilience in water systems. Future research should focus on improving data quality, accessibility, and the integration of diverse datasets to optimize the benefits of these technological advancements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20resources%20management" title="water resources management">water resources management</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20scarcity" title=" water scarcity"> water scarcity</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20governance" title=" water governance"> water governance</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20practices" title=" sustainable practices"> sustainable practices</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20management" title=" ecosystem management"> ecosystem management</a> </p> <a href="https://publications.waset.org/abstracts/194875/innovative-approaches-to-water-resources-management-addressing-challenges-through-machine-learning-and-remote-sensing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194875.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">6</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Evaluating Evaporation and Seepage Losses in Lakes Using Sentinel Images and the Water Balance Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Elsehsah">Abdelrahman Elsehsah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study is to assess changes in the water capacity of Aswan High Dam Lake (AHDL) caused by evaporation and seepage losses. To achieve this objective, a comprehensive methodology was employed. The methodology involves acquiring Sentinel-3 imagery and extracting the surface area of the lake using remote sensing techniques. Using water areas calculated from sentinel images, collected field data, and the lake’s water balance equation, monthly evaporation and seepage losses were estimated for the years 2021 and 2022. Based on the water balance method results, the average monthly evaporation losses for the year 2021 were estimated to be around 1.41 billion cubic meters (Bm3), which closely matches the estimates provided by the Ministry of Water Resources and Irrigation (MWRI) annual reports (approximately 1.37 Bm3 in the same year). This means that the water balance method slightly overestimated the monthly evaporation losses by about 2.92%. Similarly, the average monthly seepage losses for the year 2022 were estimated to be around 0.005 Bm3, while the MWRI reports indicated approximately 0.0046 Bm3. By another means, the water balance method overestimated the monthly seepage losses by about 8.70%. Furthermore, the study found that the average monthly evaporation rate within AHDL was 210.88 mm/month, which closely aligns with the computed value of approximately 204.9 mm/month by AHDA. These findings indicated that the applied water balance method, utilizing remote sensing and field data, is a reliable tool for estimating monthly evaporation and seepage losses as well as monthly evaporation rates in AHDL. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aswan%20high%20dam%20lake" title="Aswan high dam lake">Aswan high dam lake</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20balance%20equation" title=" water balance equation"> water balance equation</a>, <a href="https://publications.waset.org/abstracts/search?q=seepage%20loss" title=" seepage loss"> seepage loss</a>, <a href="https://publications.waset.org/abstracts/search?q=evaporation%20loss" title=" evaporation loss"> evaporation loss</a> </p> <a href="https://publications.waset.org/abstracts/188529/evaluating-evaporation-and-seepage-losses-in-lakes-using-sentinel-images-and-the-water-balance-equation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188529.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">34</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">38</span> Spatio-Temporal Land Cover Changes Monitoring Using Remotely Sensed Techniques in Riyadh Region, KSA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Elsehsah">Abdelrahman Elsehsah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Land Use and Land Cover (LULC) dynamics in Riyadh over a decade were comprehensively analyzed using the Google Earth Engine (GEE) platform. By harnessing the Landsat 8 Image collection and night-time light image collection from May to August for the years 2013 and 2023, we were able to generate insightful datasets capturing the changing landscape of the region. Our approach involved a Random Forest (RF) classification model that consistently displayed commendable precision scores above 92% for both years. A notable discovery from the study was the pronounced urban expansion, particularly around Riyadh city. Within a mere ten-year span, urbanization surged noticeably, affecting the broader ecological environment of the region. Interestingly, the northeastern part of Riyadh emerged as a focal point of this growth, signaling rapid urban growth of urban sprawl and development. A comparison between the two years indicates a 21.51% increase in built-up areas, revealing the transformative pace of urban sprawl. Contrastingly, vegetation cover patterns presented a more nuanced picture. While our initial hypothesis predicted a decline in vegetation, the actual findings depicted both vegetation reduction in certain pockets and new growth in others, resulting in an overall 25.89% increase. This intricate pattern might be attributed to shifting agricultural practices, afforestation efforts, or even satellite image timings not aligning with seasonal vegetation growth. The bare soil, predominant in the desert landscape of Riyadh, saw a marginal reduction of 0.37% over the decade, challenging our initial expectations. Urban and agricultural advancements in Saudi Arabia appear to have slightly reduced the expanse of barren terrains. This study, underpinned by a rigorous methodological framework, reveals the multifaceted land cover changes in Riyadh in response to urban development and environmental factors. The precise, data-driven insights provided by our analysis serve as invaluable tools for understanding urban growth trajectories, guiding urban planning, policy formulation, and sustainable development endeavors in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title="remote sensing">remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=KSA" title=" KSA"> KSA</a>, <a href="https://publications.waset.org/abstracts/search?q=ArcGIS" title=" ArcGIS"> ArcGIS</a>, <a href="https://publications.waset.org/abstracts/search?q=spatio-temporal" title=" spatio-temporal"> spatio-temporal</a> </p> <a href="https://publications.waset.org/abstracts/188743/spatio-temporal-land-cover-changes-monitoring-using-remotely-sensed-techniques-in-riyadh-region-ksa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188743.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">35</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> 3D Scanning Documentation and X-Ray Radiography Examination for Ancient Egyptian Canopic Jar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Mohamed%20Abdelrahman">Abdelrahman Mohamed Abdelrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Canopic jars are one of the vessels of funerary nature used by the ancient Egyptian in mummification process that were used to save the viscera of the mummified body after being extracted from the body and treated. Canopic jars are made of several types of materials like Limestone, Alabaster, and Pottery. The studied canopic jar dates back to Late period, located in the Grand Egyptian Museum (GEM), Giza, Egypt. This jar carved from limestone with carved hieroglyphic inscriptions, and it filled and closed by mortar from inside. Some aspects of damage appeared in the jar, such as dust, dirts, classification, wide crack, weakness of limestone. In this study, we used documentation and investigation modern techniques to document and examine the jar. 3D scanning and X-ray Radiography imaging used in applied study. X-ray imaging showed that the mortar was placed at a time when the jar contained probably viscera where the mortar appeared that not reach up to the base of the inner jar. Through the three-dimensional photography, the jar was documented, and we have 3D model of the jar, and now we have the ability through the computer to see any part of the jar in all its details. After that, conservation procedures have been applied with high accuracy to conserve the jar, including mechanical, wet, and chemical cleaning, filling wide crack in the body of the jar using mortar consisting of calcium carbonate powder mixing with primal E330 S, and consolidation, so the limestone became strong after using paraloid B72 2% concentrate as a consolidate material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vessel" title="vessel">vessel</a>, <a href="https://publications.waset.org/abstracts/search?q=limestone" title=" limestone"> limestone</a>, <a href="https://publications.waset.org/abstracts/search?q=canopic%20jar" title=" canopic jar"> canopic jar</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20scanning" title=" 3D scanning"> 3D scanning</a>, <a href="https://publications.waset.org/abstracts/search?q=X-ray%20radiography" title=" X-ray radiography"> X-ray radiography</a> </p> <a href="https://publications.waset.org/abstracts/164624/3d-scanning-documentation-and-x-ray-radiography-examination-for-ancient-egyptian-canopic-jar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164624.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">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Routine pus Swabs for Uncomplicated Abscesses – Do They Alter Our Management Plan?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Abdelrahman">Abdelrahman Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Lawrence%20Nip"> Lawrence Nip</a>, <a href="https://publications.waset.org/abstracts/search?q=Seun%20Ikotun"> Seun Ikotun</a>, <a href="https://publications.waset.org/abstracts/search?q=Iman%20Satar"> Iman Satar</a>, <a href="https://publications.waset.org/abstracts/search?q=Anur%20Miah"> Anur Miah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Incision and drainage of an abscess is a common procedure performed by the general surgeon. Pus swabs are often obtained routinely for MC&S.Our study aimed to investigate whether swabs taken at our local institution had any impact on the overall management plan for uncomplicated abscesses. Methods: We retrospectively assessed all patients presenting to University Hospital Lewisham with an abscess between October 2020 – April 2021. Exclusion criteria were recurrent abscesses, patients admitted with sepsis, known inflammatory bowel disease, immunocompromised, and those managed non-operatively. Results: We identified 131 patients who met the inclusion criteria. Two thirds were performed in theatre under general anaesthetic and the other one third under local. 63% of patients had a pus swab collected. Of these, 96% were not followed up by the requesting doctor, and there was no further patient contact. In the other 4%, the organisms cultured were flagged as atypical such as MRSA. In these cases, microbiology advice was that if the patient was clinically well and adequate drainage was achieved, then no furtherantibiotics were required. All patients were discharged before any microbiology results had come back with no subsequent change in the management plan. Average cost of pus swab = £10.10 – potentially cost saving of £1656.4 annually. Conclusion: Our study reveals that the majority of pus swabs taken from uncomplicated abscessesare not followed up by requesting doctor with no impact on the overall management plan. We, therefore, do not recommend the routine use of pus swabs for uncomplicated abscesses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pus%20swabs" title="pus swabs">pus swabs</a>, <a href="https://publications.waset.org/abstracts/search?q=uncomplated%20abscess" title=" uncomplated abscess"> uncomplated abscess</a>, <a href="https://publications.waset.org/abstracts/search?q=Pus%20MCS" title=" Pus MCS"> Pus MCS</a>, <a href="https://publications.waset.org/abstracts/search?q=follow%20up%20of%20uncomplicated%20abscess" title=" follow up of uncomplicated abscess"> follow up of uncomplicated abscess</a> </p> <a href="https://publications.waset.org/abstracts/144561/routine-pus-swabs-for-uncomplicated-abscesses-do-they-alter-our-management-plan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144561.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">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Design of a Rectifier with Enhanced Efficiency and a High-gain Antenna for Integrated and Compact-size Rectenna Circuit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rawaa%20Maher">Rawaa Maher</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Allam"> Ahmed Allam</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruichi%20Kanaya"> Haruichi Kanaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20B.%20Abdelrahman"> Adel B.

These scenarios were simulated programs such as MATLAB and Python to test how the V2V system would respond to the different scenarios and warn the car drivers exposed to the threat of collisions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=V2V%20communication" title="V2V communication">V2V communication</a>, <a href="https://publications.waset.org/abstracts/search?q=vehicle%20to%20vehicle%20scenarios" title=" vehicle to vehicle scenarios"> vehicle to vehicle scenarios</a>, <a href="https://publications.waset.org/abstracts/search?q=VANET" title=" VANET"> VANET</a>, <a href="https://publications.waset.org/abstracts/search?q=FCW" title=" FCW"> FCW</a>, <a href="https://publications.waset.org/abstracts/search?q=EEBL" title=" EEBL"> EEBL</a>, <a href="https://publications.waset.org/abstracts/search?q=IMA" title=" IMA"> IMA</a>, <a href="https://publications.waset.org/abstracts/search?q=Laplacian%20matrix" title=" Laplacian matrix"> Laplacian matrix</a> </p> <a href="https://publications.waset.org/abstracts/156914/vehicle-to-vehicle-communication-collision-avoidance-scenarios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156914.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">33</span> Computational Models for Accurate Estimation of Joint Forces</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Elnour%20Abdelrahman%20Eltayeb">Ibrahim Elnour Abdelrahman Eltayeb</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational modelling is a method used to investigate joint forces during a movement. It can get high accuracy in the joint forces via subject-specific models. However, the construction of subject-specific models remains time-consuming and expensive.

It appraised the impact of these alterations on the accuracy of the estimated joint forces. It found different strategies of alterations: joint model, muscle model, and an optimisation problem. All these alterations affected joint contact force accuracy, so showing the potential for improving the model predictions without involving costly and time-consuming medical images. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20force" title="joint force">joint force</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20model" title=" joint model"> joint model</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation%20problem" title=" optimisation problem"> optimisation problem</a>, <a href="https://publications.waset.org/abstracts/search?q=validation" title=" validation"> validation</a> </p> <a href="https://publications.waset.org/abstracts/158393/computational-models-for-accurate-estimation-of-joint-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158393.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">170</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">32</span> Study of Pottery And Glazed Canopic Vessels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Mohamed">Abdelrahman Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The ancient Egyptians used canopic vessels in embalming operations in order to preserve the guts of the mummified corpse.

Late diagnosis can cause severe problems due to the late treatment and to the misconceptions and lack of awareness as a whole towards these disorders. Moreover, electroencephalography (EEG) has played a vital role in the assessment of neural function in children. Therefore, quantitative EEG measurement will be utilized as a tool for use in the evaluation of patients who may have ADHD, epilepsy, and autism. We propose a screening tool that uses EEG signals and machine learning algorithms to detect these disorders at an early age in an automated manner. The proposed classifiers used with epilepsy as a step taken for the work done so far, provided an accuracy of approximately 97% using SVM, Naïve Bayes and Decision tree, while 98% using KNN, which gives hope for the work yet to be conducted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ADHD" title="ADHD">ADHD</a>, <a href="https://publications.waset.org/abstracts/search?q=autism" title=" autism"> autism</a>, <a href="https://publications.waset.org/abstracts/search?q=epilepsy" title=" epilepsy"> epilepsy</a>, <a href="https://publications.waset.org/abstracts/search?q=EEG" title=" EEG"> EEG</a>, <a href="https://publications.waset.org/abstracts/search?q=SVM" title=" SVM"> SVM</a> </p> <a href="https://publications.waset.org/abstracts/108018/eeg-based-screening-tool-for-school-students-brain-disorders-using-machine-learning-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108018.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">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Impact of Health Sector Economic Reforms in Underdeveloped Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haga%20Abdelrahman%20Elimam">Haga Abdelrahman Elimam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the connotation, and some of the realistic implications, of the economic reform of health sector in under developed countries. The paper investigates the issues that economic reforms have to address, and the policy targets they are considered to accomplish. The work argues that the development of economic reform is not connected only with understanding the priorities and refining them, furthermore with reformation and restructuring the organizations through which health policies are employed. Considering various organizational values, that are likely to be regular to all economic reform programs, a regulatory approach to institutional reform is unsuitable. The paper further investigates the selection of economic reform that may as well influence via technical suggestions and analysis, but the verdict to continue, and the consequent success of execution, eventually depends on the progressive political sustainability. The paper concludes by giving examples of institutional reforms from various underdeveloped countries and includes recommendation of the responsibility and control of donor organizations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=economic%20reform" title="economic reform">economic reform</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20sector" title=" health sector"> health sector</a>, <a href="https://publications.waset.org/abstracts/search?q=underdeveloped%20countries" title=" underdeveloped countries"> underdeveloped countries</a>, <a href="https://publications.waset.org/abstracts/search?q=technical%20suggestions" title=" technical suggestions"> technical suggestions</a> </p> <a href="https://publications.waset.org/abstracts/27909/impact-of-health-sector-economic-reforms-in-underdeveloped-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27909.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">423</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> The Effect of the Thermal Temperature and Injected Current on Laser Diode 808 nm Output Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20H.%20Abuelhassan">Hassan H.

The output power increases by the increasing the injected current and temperature. We also showed that the increasing of the injected current results rising in heat, which also, results into decreasing of the laser diode output power during the highest temperature as well.

AA-Ph was synthesized through single-step melt polycondensation of adipic acid (AA) and phloroglucinol (Ph) and then incorporated into RPET before spinning. The addition of AA-Ph significantly improves the dye uptake of recycled PET when dyed with disperse dye blue 56 due to the introduction of polar groups and aromatic rings. The blends RPET-3 and RPET-5 show strong abrasion resistance, dyeability, and washing fastness. Furthermore, these blends exhibit high moisture absorbance owing to the polar groups and aromatic structures, as demonstrated by exhaustion tests, which enhance perspiration absorption for added comfort in apparel. Overall, RPET-3 and RPET-5 blends are well-suited for various textile applications, especially in garment manufacturing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=recycled%20poly%20%28ethylene%20terephthalate%29" title="recycled poly (ethylene terephthalate)">recycled poly (ethylene terephthalate)</a>, <a href="https://publications.waset.org/abstracts/search?q=hyperbranched%20polyester" title=" hyperbranched polyester"> hyperbranched polyester</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeability" title=" dyeability"> dyeability</a>, <a href="https://publications.waset.org/abstracts/search?q=dye%20blue" title=" dye blue"> dye blue</a> </p> <a href="https://publications.waset.org/abstracts/194927/enhancing-the-dyeability-and-performance-of-recycled-polyethylene-terephthalate-with-hyperbranched-polyester" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194927.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">4</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Nitrogen-Doped Ultrananocrystalline Diamond/Hydrogenated Amorphous Carbon Composite Films Prepared by Coaxial Arc Plasma Deposition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Zkria">Abdelrahman Zkria</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsuyoshi%20Yoshitake"> Tsuyoshi Yoshitake</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diamond is one of the most interesting semiconducting carbon materials owing to its unique physical and chemical properties, yet its application in electronic devices is limited due to the difﬁculty of realizing n-type conduction by nitrogen doping.

Accidents, burns and genetic problems such as bowing of body parts of people have a negative impact on their mental health with their appearance and this makes them feel uncomfortable and underestimated. The approach presents a revolutionary deep learning-based image inpainting method that analyses the various picture structures and corrects damaged images. In this study, A model is proposed based on the in-painting of medical images with Stable Diffusion Inpainting method. Reconstructing missing and damaged sections of an image is known as image inpainting is a key progress facilitated by deep neural networks.

To implement these, factories tend to use advanced systems that could alter complicity to simplicity and rudimentary to advancement. Cloud Manufacturing is a new movement that aims to mirror and integrate cloud computing into manufacturing. Amongst cloud manufacturing various advantages are decreasing the human involvements and increasing the dependency on automated machines, which in turns decreases human errors and increases efficiency. A reliable and extraordinary performance processes with minimum errors are highly desired factors of today’s manufacturers. At the glance it seems to be the best alternative, however, the implementation of a cloud system can be very challenging. This work investigates cloud manufacturing in details, it outlines its advantages and disadvantages by converting a local factory in Kuwait to a cloud-ready system. Initially the flow of the factory’s manufacturing process has been analyzed identifying the bottlenecks and illustrating how cloud manufacturing can eliminate them. Following this an automation process has been analyzed and implemented. A comparison between the process before and after the adaptation has been carried out showing the effects on the cost, the output and the efficiency of the process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20manufacturing" title="cloud manufacturing">cloud manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=automation" title=" automation"> automation</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait%20industrial%20sector" title=" Kuwait industrial sector"> Kuwait industrial sector</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20digital%20manufacturing" title=" advanced digital manufacturing"> advanced digital manufacturing</a> </p> <a href="https://publications.waset.org/abstracts/16143/advanced-digital-manufacturing-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16143.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">771</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Level of Behavioral Development for Hepatitis C Virus Cases Versus Their Contacts: Does Infection Make a Difference and What Is Beyond?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammal%20M.%20Metwally">Ammal M.

The study was conducted over one year from Jan. 2011 till Jan. 2012. Knowledge, attitude and behavior of 540 HCV patients and 102 of their contacts were assessed and the level of behavioral development was determined. The study revealed that the majority of patients and contacts knew that HCV infection is dangerous with perceived concern for early diagnosis and treatment. More than 75% knew the correct modes of transmission. The assessment showed positive attitudes towards the recommended practices with the intention to adopt those practices. Strategies to create opportunities to continue the recommended behaviors should be adopted together with the reinforcement of social support. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatitis%20C%20virus" title="hepatitis C virus">hepatitis C virus</a>, <a href="https://publications.waset.org/abstracts/search?q=level%20of%20behavioral%20development" title=" level of behavioral development"> level of behavioral development</a>, <a href="https://publications.waset.org/abstracts/search?q=recommended%20behaviors" title=" recommended behaviors"> recommended behaviors</a> </p> <a href="https://publications.waset.org/abstracts/2281/level-of-behavioral-development-for-hepatitis-c-virus-cases-versus-their-contacts-does-infection-make-a-difference-and-what-is-beyond" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2281.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">397</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> The Current Status of Integrating Information and Communication Technology in Teaching at Sultan Qaboos University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdelrahman">Ahmed Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdelraheem"> Ahmed Abdelraheem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are many essential factors affecting the integration of information and communication technology (ICT) into teaching and learning, including technology infrastructure, institutional support, professional development, and faculty members’ beliefs regarding ICT integration. The present research project investigated the current status of integrating ICT into teaching and learning at Sultan Qaboos University (SQU). A sample of 220 faculty members from six different colleges and four administrators from the Center of Educational Technology (CET) and the Center for Information Systems (CIS) at SQU in Oman were chosen, and quantitative, qualitative design using a semi-structured questionnaire, interviews and checklists were employed. The findings show that SQU had a high availability of ICT infrastructure in terms of hardware, software, and support services, as well as adequate computer labs for educational purposes. However, the results also indicated that, although SQU provided a series of professional development workshops related to using ICT in teaching, few faculty members were interested. Furthermore, the finding indicated that the degree of ICT integration into teaching at SQU was at a medium level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=information%20and%20communication%20technology" title="information and communication technology">information and communication technology</a>, <a href="https://publications.waset.org/abstracts/search?q=integration" title=" integration"> integration</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20development" title=" professional development"> professional development</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching" title=" teaching"> teaching</a> </p> <a href="https://publications.waset.org/abstracts/117012/the-current-status-of-integrating-information-and-communication-technology-in-teaching-at-sultan-qaboos-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117012.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">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Prediction of the Mechanical Power in Wind Turbine Powered Car Using Velocity Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Alghazali">Abdelrahman Alghazali</a>, <a href="https://publications.waset.org/abstracts/search?q=Youssef%20Kassem"> Youssef Kassem</a>, <a href="https://publications.waset.org/abstracts/search?q=H%C3%BCseyin%20%C3%87amur"> Hüseyin Çamur</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozan%20Erenay"> Ozan Erenay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Savonius is a drag type vertical axis wind turbine. Savonius wind turbines have a low cut-in speed and can operate at low wind speed. This makes it suitable for electricity or mechanical generation in low-power applications such as individual domestic installations. Therefore, the primary purpose of this work was to investigate the relationship between the type of Savonius rotor and the torque and mechanical power generated. And it was to illustrate how the type of rotor might play an important role in the prediction of mechanical power of wind turbine powered car. The main purpose of this paper is to predict and investigate the aerodynamic effects by means of velocity analysis on the performance of a wind turbine powered car by converting the wind energy into mechanical energy to overcome load that rotates the main shaft. The predicted results based on theoretical analysis were compared with experimental results obtained from literature. The percentage of error between the two was approximately around 20%. Prediction of the torque was done at a wind speed of 4 m/s, and an angular velocity of 130 RPM according to meteorological statistics in Northern Cyprus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20power" title="mechanical power">mechanical power</a>, <a href="https://publications.waset.org/abstracts/search?q=torque" title=" torque"> torque</a>, <a href="https://publications.waset.org/abstracts/search?q=Savonius%20rotor" title=" Savonius rotor"> Savonius rotor</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20car" title=" wind car"> wind car</a> </p> <a href="https://publications.waset.org/abstracts/73215/prediction-of-the-mechanical-power-in-wind-turbine-powered-car-using-velocity-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73215.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">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Compost Enriched with Actinomyces and Bacillus Polymyxa Algae as a Partial Substitute for Mineral N in Ewaise Mango Orchards</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Sheba%20Abdelrahman">Abdelaziz Sheba Abdelrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Compost enriched with actinomyces and Bacillus polymyxa algae as a Partial Substitute for Mineral N in Ewaise Mango Orchards Organic fertiliser, compost enriched with actinomyces, and the biofertilizer Bacillus polymyxa algae were used as a partial replacement for mineral N fertiliser in Ewaise mango orchards during the 2019 and 2020 seasons. When compared to using mineral N alone, the results showed that reducing the percentage of mineral N fertiliser from 100 to 50% and using compost enriched with actinomyces at 25 to 50% and Bacillus polymyxa had an announced promotion on leaf area, total chlorophylls, leaf N, P, and K, yield, and fruit quality. The use of compost enriched with actinomyces and Bacillus polymyxa, as well as mineral N, resulted in a significant decrease in nitrite in the pulp. Reducing mineral N to 25% of the suitable N had a negative impact on yield. The application of appropriate N via 50% inorganic N + compost enriched with actinomyces at 50% + Bacillus polymyxa algae increased yield quantitatively and qualitatively in Ewaise mango orchards.

Through this research, bentonite clay can be used to remove organic hydrocarbon compounds, such as heptane and octane, resulting from oil spills in seawater. Bentonite clay can be obtained from the Kholayaz area, located north of Jeddah, at a distance of 80 km. Chemical analysis shows that bentonite clay consists of a mixture of silica, alumina and oxides of some elements. Bentonite clay can be activated in order to raise its adsorption efficiency and to make it suitable for removing pollutants using an ionic organic solvent. It is necessary to study some of the factors that could be in the efficiency of bentonite clay in removing oily organic compounds, such as the time of contact of the clay with heptane and octane solutions, pH and temperature, in order to reach the highest adsorption capacity of bentonite clay. The temperature can be a few degrees Celsius higher. The adsorption capacity of the clay decreases when the temperature is raised more than 4°C to reach its lowest value at the temperature of 50°C. The results show that the friction time of 30 minutes and the pH of 6.8 is the best conditions to obtain the highest adsorption capacity of the clay, 467 mg in the case of heptane and 385 mg in the case of octane compound. Experiments conducted on bentonite clay were encouraging to select it to remove heavy molecular weight pollutants such as petroleum compounds under study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorbent" title="adsorbent">adsorbent</a>, <a href="https://publications.waset.org/abstracts/search?q=bentonite%20clay" title=" bentonite clay"> bentonite clay</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20spills" title=" oil spills"> oil spills</a>, <a href="https://publications.waset.org/abstracts/search?q=removal" title=" removal"> removal</a> </p> <a href="https://publications.waset.org/abstracts/163185/adsorbent-removal-of-oil-spills-using-bentonite-clay" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163185.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">18</span> Bitcoin, Blockchain and Smart Contract: Attacks and Mitigations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rasslan">Mohamed Rasslan</a>, <a href="https://publications.waset.org/abstracts/search?q=Doaa%20Abdelrahman"> Doaa Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20M.%20Nasreldin"> Mahmoud M.

Smart contracts are programs that are stored on a blockchain. Smart contracts are executed when predetermined conditions are fulfilled. Smart contracts automate the agreement execution in order to make sure that all participants immediate-synchronism of the outcome-certainty, without any intermediary's involvement or time loss. Currently, the Bitcoin market worth billions of dollars. Bitcoin could be transferred from one purchaser to another without the need for an intermediary bank. Network nodes through cryptography verify bitcoin transactions, which are registered in a public-book called “blockchain”. Bitcoin could be replaced by other coins, merchandise, and services. Rapid growing of the bitcoin market-value, encourages its counterparts to make use of its weaknesses and exploit vulnerabilities for profit. Moreover, it motivates scientists to define known vulnerabilities, offer countermeasures, and predict future threats. In his paper, we study blockchain technology and bitcoin from the attacker’s point of view. Furthermore, mitigations for the attacks are suggested, and contemporary security solutions are discussed.

The lack of proper definition of the function of the brain ventricles and the central spinal canal has made it difficult to ascertain the pathophysiology of its different disease conditions or to treat them. This study aims to review the simple physics that could explain the basic function of the CNS ventricular system and to suggest new ways of approaching its pathology. There are probably more physical factors to consider than only the pressure. Monro-Killie hypothesis focuses on volume and subsequently pressure to direct our surgical management in different disease conditions. However, the enlarged volume of the ventricles in normal pressure hydrocephalus does not move any blood or brain outside the skull. Also, in idiopathic intracranial hypertension, the very high intracranial pressure rarely causes brain herniation. On this note, the continuum of the intracranial cavity with the spinal canal makes it a whole unit and hence the defect in the theory. In this study, adding different factors to the equation like brain and CSF density and positions of the brain in space, in addition to the volume and pressure, aims to identify how the ventricles are important in the CNS homeostasis. In addition, increasing the variables that we analyze to treat different CSF pathological conditions should increase our understanding and hence accuracy of treatment of such conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communicating%20hydrocephalus" title="communicating hydrocephalus">communicating hydrocephalus</a>, <a href="https://publications.waset.org/abstracts/search?q=functions%20of%20the%20ventricles" title=" functions of the ventricles"> functions of the ventricles</a>, <a href="https://publications.waset.org/abstracts/search?q=idiopathic%20intracranial%20hypertension%20physics%20of%20CSF" title=" idiopathic intracranial hypertension physics of CSF"> idiopathic intracranial hypertension physics of CSF</a> </p> <a href="https://publications.waset.org/abstracts/129705/functions-and-pathophysiology-of-the-ventricular-system-review-of-the-underlying-basic-physics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Finite Element Modeling of Friction Stir Welding of Dissimilar Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fadi%20Al-Badour">Fadi Al-Badour</a>, <a href="https://publications.waset.org/abstracts/search?q=Nesar%20Merah"> Nesar Merah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Shuaib"> Abdelrahman Shuaib</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelaziz%20Bazoune"> Abdelaziz Bazoune</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current work, a Coupled Eulerian Lagrangian (CEL) model is developed to simulate the friction stir welding (FSW) process of dissimilar Aluminum alloys (Al 6061-T6 with Al 5083-O). The model predicts volumetric defects, material flow, developed temperatures, and stresses in addition to tool reaction loads. Simulation of welding phase is performed by employing a control volume approach, whereas the welding speed is defined as inflow and outflow over Eulerian domain boundaries. Only material softening due to inelastic heat generation is considered and material behavior is assumed to obey Johnson-Cook’s Model. The model was validated using published experimentally measured temperatures, at similar welding conditions, and by qualitative comparison of dissimilar weld microstructure. The FE results showed that most of developed temperatures were below melting and that the bulk of the deformed material in solid state. The temperature gradient on AL6061-T6 side was found to be less than that of Al 5083-O. Changing the position Al 6061-T6 from retreating (Ret.) side to advancing (Adv.) side led to a decrease in maximum process temperature and strain rate. This could be due to the higher resistance of Al 6061-T6 to flow as compared to Al 5083-O. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=friction%20stir%20welding" title="friction stir welding">friction stir welding</a>, <a href="https://publications.waset.org/abstracts/search?q=dissimilar%20metals" title=" dissimilar metals"> dissimilar metals</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20modeling" title=" finite element modeling"> finite element modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20Eulerian%0D%0ALagrangian%20Analysis" title=" coupled Eulerian Lagrangian Analysis"> coupled Eulerian Lagrangian Analysis</a> </p> <a href="https://publications.waset.org/abstracts/2021/finite-element-modeling-of-friction-stir-welding-of-dissimilar-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2021.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">331</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">15</span> Assessing Psycho-Social Stressors for Chronically Infected Hepatitis C Virus Patients in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammal%20M.%20Metwally">Ammal M.

Objective: The study was conducted to determine the psycho-social stressors accompanying Hepatitis C virus (HCV) chronic infection. The study focused on immediate and later on reactions to being diagnosed as infected HCV patients. Effect of HCV on disruption of patients’ relationships in term of family relationship and friendship, employment and financial status was assessed. The magnitude and causes of the social stigma and its relation to awareness about illness, level of education were also assessed. Methods: During this study the subjective experiences of people having HCV was explored through a designed questionnaire targeted 540 cases; 359 males and 181 females from ten out of 21 National Treatment Reference Centers of National Hepatology and Tropical Medicine Research Institutes of Ministry of Health (MOH) hospitals. The study was conducted along a period of six months from September 2011 to March 2012. Results: The study revealed that the financial problems are the commonest problems faced by 75.5 % of the cases. More than 70% of the cases suffered from immediate sadness versus 67.4% suffered from worry. Social stigma was reported by 13 % of HCV +patients, the majority of which were females. Conclusions: Exploring the psychosocial consequences of HCV infection can act as pressing motivators for behavior change needed for limiting HCV endemicity in Egypt. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Egypt" title="Egypt">Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=HCV%20infection" title=" HCV infection"> HCV infection</a>, <a href="https://publications.waset.org/abstracts/search?q=psycho-social%20adjustment" title=" psycho-social adjustment"> psycho-social adjustment</a>, <a href="https://publications.waset.org/abstracts/search?q=stigma" title=" stigma"> stigma</a> </p> <a href="https://publications.waset.org/abstracts/3471/assessing-psycho-social-stressors-for-chronically-infected-hepatitis-c-virus-patients-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3471.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">367</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">14</span> A Questionnaire Survey Reviewing Radiographers' Knowledge of Computed Tomography Exposure Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Rawashdeh">Mohammad Rawashdeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mark%20McEntee"> Mark McEntee</a>, <a href="https://publications.waset.org/abstracts/search?q=Maha%20Zaitoun"> Maha Zaitoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Abdelrahman"> Mostafa Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Patrick%20Brennan"> Patrick Brennan</a>, <a href="https://publications.waset.org/abstracts/search?q=Haytham%20Alewaidat"> Haytham Alewaidat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Lewis"> Sarah Lewis</a>, <a href="https://publications.waset.org/abstracts/search?q=Charbel%20Saade"> Charbel Saade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the tremendous advancements that have been generated by Computed Tomography (CT) in the field of diagnosis, concerns have been raised about the potential cancer induction risk from CT because of the exponentially increased use of it in medicine. This study aims at investigating the application and knowledge of practicing radiographers in Jordan about CT radiation. In order to collect the primary data of this study, a questionnaire was designed and distributed by social media using a snow-balling sampling method. The respondents (n=54) have answered 36 questions including the questions about their demographic information, knowledge about Diagnostic Reference Levels (DRLs), CT exposure and adaptation of pediatric patients exposure. The educational level of the respondents was either at a diploma degree (35.2%) or bachelor (64.8%). The results of this study have indicated a good level of general knowledge between radiographers about the relationship between image quality, exposure parameters, and patient dose. The level of knowledge related to DRL was poor where less than 7.4 percent of the sample members were able to give specific values for a number of common anatomical fields, including abdomen, brain, and chest. Overall, Jordanian radiographers need to gain more knowledge about the expected levels of the dose when applying good practice. Additional education on DRL or DRL inclusion in educational programs is highlighted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography" title="computed tomography">computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20scan" title=" CT scan"> CT scan</a>, <a href="https://publications.waset.org/abstracts/search?q=DRLs" title=" DRLs"> DRLs</a>, <a href="https://publications.waset.org/abstracts/search?q=exposure%20parameters" title=" exposure parameters"> exposure parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20quality" title=" image quality"> image quality</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20dose" title=" radiation dose"> radiation dose</a> </p> <a href="https://publications.waset.org/abstracts/107826/a-questionnaire-survey-reviewing-radiographers-knowledge-of-computed-tomography-exposure-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107826.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">143</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">13</span> Factors Associated with Mammography Screening Behaviors: A Cross-Sectional Descriptive Study of Egyptian Women </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salwa%20Hagag%20Abdelaziz">Salwa Hagag Abdelaziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Naglaa%20Fathy%20Youssef"> Naglaa Fathy Youssef</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadia%20Abdellatif%20Hassan"> Nadia Abdellatif Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Wesam%20Abdelrahman"> Rasha Wesam Abdelrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast cancer is considered as a substantial health concern and practicing mammography screening [MS] is important in minimizing its related morbidity. So it is essential to have a better understanding of breast cancer screening behaviors of women and factors that influence utilization of them. The aim of this study is to identify the factors that are linked to MS behaviors among the Egyptian women. A cross-sectional descriptive design was carried out to provide a snapshot of the factors that are linked to MS behaviors. A convenience sample of 311 women was utilized and all eligible participants admitted to the Women Imaging Unit who are 40 years of age or above, coming for mammography assessment, not pregnant or breast feeding and who accepted to participate in the study were included. A structured questionnaire was developed by the researchers and contains three parts; Socio-demographic data; Motivating factors associated with MS; and association between MS and model of behavior change. The analyzed data indicated that most of the participated women (66.6 %) belonged to the age group of 40-49.A high proportion of participants (58.1%) of group having previous MS influenced by their neighbors to practice MS, whereas 32.7 % in group not having previous MS were influenced by family members which indicated significant differences (P <0.05). Doctors and media are shown to be the least influence of others to practice MS. Women with intention to have a future mammogram had higher OR (1.404) for practicing MS compared with women with no intention. Further studies are needed to examine the relation between Trans-theoretical Model [TTM] and practicing MS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=mammography" title=" mammography"> mammography</a>, <a href="https://publications.waset.org/abstracts/search?q=screening%20behaviors" title=" screening behaviors"> screening behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=morbidity" title=" morbidity"> morbidity</a> </p> <a href="https://publications.waset.org/abstracts/28433/factors-associated-with-mammography-screening-behaviors-a-cross-sectional-descriptive-study-of-egyptian-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28433.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">442</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">12</span> Time-Domain Analysis Approaches of Soil-Structure Interaction: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Taha">Abdelrahman Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Malekghaini"> Niloofar Malekghaini</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Ebrahimian"> Hamed Ebrahimian</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Motamed"> Ramin Motamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper compares the substructure and direct methods for soil-structure interaction (SSI) analysis in the time domain. In the substructure SSI method, the soil domain is replaced by a set of springs and dashpots, also referred to as the impedance function, derived through the study of the behavior of a massless rigid foundation. The impedance function is inherently frequency dependent, i.e., it varies as a function of the frequency content of the structural response. To use the frequency-dependent impedance function for time-domain SSI analysis, the impedance function is approximated at the fundamental frequency of the structure-soil system. To explore the potential limitations of the substructure modeling process, a two-dimensional reinforced concrete frame structure is modeled using substructure and direct methods in this study. The results show discrepancies between the simulated responses of the substructure and the direct approaches. To isolate the effects of higher modal responses, the same study is repeated using a harmonic input motion, in which a similar discrepancy is still observed between the substructure and direct approaches. It is concluded that the main source of discrepancy between the substructure and direct SSI approaches is likely attributed to the way the impedance functions are calculated, i.e., assuming a massless rigid foundation without considering the presence of the superstructure. Hence, a refined impedance function, considering the presence of the superstructure, shall be developed. This refined impedance function is expected to significantly improve the simulation accuracy of the substructure approach for structural systems whose behavior is dominated by the fundamental mode response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20approach" title="direct approach">direct approach</a>, <a
