Having faced threats of persecution and assassination, Eissa is a controversial figure in Egyptian media, and his works always pose a trigger of outrage and conversation. His book The Preacher, his movie The Guest, and his TV show Faten Amal Harby all led to some controversy unfolding in Egyptian society, and all led to conversations erupting in Egyptian households and on social media platforms. Through a close reading of his written work and an analytic watch of his work on-screen, the paper delves into the details of the intentions behind and the repercussions of Ibrahim Eissa's work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=censorship" title="censorship">censorship</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a> </p> <a href="https://publications.waset.org/abstracts/175686/the-works-of-ibrahim-eissa-a-controversy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175686.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">707</span> Benefits and Drawbacks of Robotic Firefighting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukhtar%20Ibrahim%20Bello">Mukhtar Ibrahim Bello</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20U.%20Aikawa"> Ibrahim U.

However, some physical and chemical demonstrations of the laser effect upon interaction with the corneal tissue are still not fully explained. Therefore, different computational and mathematical models have been implemented to predict the depth of the ablated channel and calculate the ablation threshold and the local temperature rise. In the current paper, we present a modified model that aims to answer some of the open questions about the ablation threshold, the ablation rate, and the physical and chemical mechanisms of that action. The proposed model consists of three parts. The first part deals with possible photochemical reactions between the incident photons and various components of the cornea (collagen, water, etc.). Such photochemical reactions may end by photo-ablation or just the electronic excitation of molecules. Then a chemical reaction is responsible for the ablation threshold. Finally, another chemical reaction produces fragments that can be cleared out. The model takes into account all processes at the same time with different probabilities. Moreover, the effect of applying different laser wavelengths that have been studied before, namely the common excimer laser (193-nm) and the solid state lasers (213-nm & 266-nm), has been investigated. Despite the success and ubiquity of the ArF laser, the presented results reveal that a carefully designed 213-nm laser gives the same results with lower operational drawbacks. Moreover, the use of mode locked laser could also decrease the risk of heat generation and diffusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UV%20lasers" title="UV lasers">UV lasers</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a>, <a href="https://publications.waset.org/abstracts/search?q=corneal%20ablation" title=" corneal ablation"> corneal ablation</a>, <a href="https://publications.waset.org/abstracts/search?q=photochemical%20ablation" title=" photochemical ablation"> photochemical ablation</a> </p> <a href="https://publications.waset.org/abstracts/160661/modified-model-for-uv-laser-corneal-ablation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160661.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">89</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">705</span> FLC with 3DSVM for 4LEG 4WIRE Shunt Active Power Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhalim%20Kessal">Abdelhalim Kessal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Chebabhi"> Ali Chebabhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a controller based on fuzzy logic control (FLC) associated to Three Dimensional Space Vector Modulation (3DSVM) is applied for shunt active filter in αβo axes domain.

Numerical investigations into the transmission loss values of these ring-shaped attenuators using finite element method simulations (COMSOL Multiphysics) have been presented in the frequency range of 100– 1000 Hz.

However, they still lack the low limit of detection (LOD) and there still a place for improvement. SPR conventional sensors are based on the detection of a dip in the reflectivity spectrum which is relatively wide. To improve the performance of these sensors, many techniques and methods proposed either to reduce the width of the dip or to increase the sensitivity. Together with that, profiting from the sharp jump in the phase spectrum under SPR, several works suggested the extraction of the phase of the reflected wave. However, existing phase measurement setups are in general more complicated compared to the conventional setups, require more stability and are very sensitive to external vibrations and noises. In this study, a simple polarimetric technique for phase extraction under SPR is presented, followed by a theoretical error analysis and an experimental verification. The advantages of the proposed technique upon existing techniques will be elaborated, together with conclusions regarding the best polarimetric function, and its corresponding optimal metal layer range of thicknesses to use under the conventional Kretschmann-Raether configuration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasmonics" title="plasmonics">plasmonics</a>, <a href="https://publications.waset.org/abstracts/search?q=polarimetry" title=" polarimetry"> polarimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20films" title=" thin films"> thin films</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20sensors" title=" optical sensors"> optical sensors</a> </p> <a href="https://publications.waset.org/abstracts/53083/optimal-configuration-for-polarimetric-surface-plasmon-resonance-sensors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53083.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">404</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">696</span> Fuzzy Analytic Hierarchy Process for Determination of Supply Chain Performance Evaluation Criteria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Cil">Ibrahim Cil</a>, <a href="https://publications.waset.org/abstracts/search?q=Onur%20Kurtcu"> Onur Kurtcu</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20Ibrahim%20Demir"> H.

Objective: In this study, the inhibitory effects of fruit extracts of Parinari macrophylla, Detarium microcarpum, Ziziphus spina-christi, Z. mairei and Parkia biglobosa were investigated against intestinal maltase and sucrase. Methods: Rats were given co-administration of the fruit extracts with maltose or sucrose and blood glucose levels were measured at 0, 30, 90 and 120 min. Results: The glucose-time curves indicated that all the fruits had the most potent inhibitory effects on both maltase and sucrase within the first 30 min. The computed Area Under the Curves (AUC0-120)for all the fruits indicated more potent inhibitory effects against intestinal maltase than sucrase.The ED50 range for the fruits extract against maltase and sucrase were 647.15-1118.35 and 942.44-1851.94 mg/kg bw respectively. Conclusion: The data suggests that the fruits could prevent postprandial hyperglycemia via inhibition of intestinal maltase and sucrase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes%20mellitus" title="diabetes mellitus">diabetes mellitus</a>, <a href="https://publications.waset.org/abstracts/search?q=fruits" title=" fruits"> fruits</a>, <a href="https://publications.waset.org/abstracts/search?q=%CE%B1-glucosidases" title=" α-glucosidases"> α-glucosidases</a>, <a href="https://publications.waset.org/abstracts/search?q=maltase" title=" maltase"> maltase</a>, <a href="https://publications.waset.org/abstracts/search?q=sucrase" title=" sucrase"> sucrase</a> </p> <a href="https://publications.waset.org/abstracts/43113/in-vivo-maltase-and-sucrase-inhibitory-activities-of-five-underutilized-nigerian-edible-fruits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43113.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">384</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">692</span> Challenges of Domestic Water Security for Sustainable Development in North Central Belt of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Ibbi%20Ibrahim">Samuel Ibbi Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaiah%20Ndalassan%20Ibrahim"> Isaiah Ndalassan Ibrahim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accessibility and availability of good quality water have become a major concern among different users. This paper examines the caustic importance of water security in relation to people’s desire for survival. It observed the democratic ideology of national policy on domestic water supply and demand and its implementation for national and societal development. It used analogy on equilibrium approach to ascertain the household water security. In most communities, it is glaring that several public water management in operation for several years are hardly performing efficiently to reach equilibrium demand. Moreover most settlements being rural or urban lack effective public water system that could ensure regular supplies to the population. The terrain and gradual declining of efficient rainfall northward poses great challenge to the region in managing water supply and demand adequately. This study itemized the need for the government to get clear strategy for a sustainable development on better water efficiency. Partnership in providing workable policy on water security is considered apparently important. It is also suggested that water plant treatment should be established in every medium-sized towns in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=good%20quality%20of%20water" title="good quality of water">good quality of water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20accessibility" title=" water accessibility"> water accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20availability" title=" water availability"> water availability</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20sustainable" title=" water sustainable "> water sustainable </a> </p> <a href="https://publications.waset.org/abstracts/36333/challenges-of-domestic-water-security-for-sustainable-development-in-north-central-belt-of-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36333.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">527</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">691</span> Psychiatric Symptoms in Keratoconus: Analyzing Anxiety and Depression in Affected Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nida%20Amin">Nida Amin</a>, <a href="https://publications.waset.org/abstracts/search?q=Fahad%20Tanveer"> Fahad Tanveer</a>, <a href="https://publications.waset.org/abstracts/search?q=Hina%20Shabbir"> Hina Shabbir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayesha%20Saeed"> Ayesha Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Attiqa%20Riaz"> Attiqa Riaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The gradual progression of corneal disorder keratoconus significantly impairs eyesight and quality of life, increasing the likelihood of depression.

It catalyzes the reduction of dihydrofolate to tetrahydrofolate and intimately couples with thymidylate synthase. Thymidylate synthase is a crucial enzyme that catalyzes the reductive methylation of (dUMP) to (dTMP) utilizing N5, N10-methylenetetrahydrofolate as a cofactor. A new series of 2-substituted thio-quinazolin-4-one analogs was designed that possessed electron withdrawing or donating functional groups (Cl or OCH3) at position 6- or 7-, 4-methoxyphenyl function at position 3-.The thiol function is used to connect to either 1,2,4-triazole, or 1,3,4-thiadiazole via a methylene bridge. Most of the functional groups designed to be accommodated on the quinazoline ring such as thioether, alkyl to increase lipid solubility of polar compounds, a character very much needed in the nonclassical DHFR inhibitors. The target compounds were verified with spectral data and elemental analysis. DHFR inhibitions, as well as antitumor activity, were applied on three cell lines (MCF-7, CACO-2, HEPG-2). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonclassical%20antifolates" title="nonclassical antifolates">nonclassical antifolates</a>, <a href="https://publications.waset.org/abstracts/search?q=DHFR%20Inhibitors" title=" DHFR Inhibitors"> DHFR Inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=antitumor%20activity" title=" antitumor activity"> antitumor activity</a>, <a href="https://publications.waset.org/abstracts/search?q=quinazoline%20ring" title=" quinazoline ring"> quinazoline ring</a> </p> <a href="https://publications.waset.org/abstracts/53324/nonclassical-antifolates-synthesis-biological-evaluation-and-molecular-modeling-study-of-some-new-quinazolin-4-one-analogues-as-dihydrofolate-reductase-inhibitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53324.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">394</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">689</span> Influence of Cathodic Protection on High Strength, Pre-Stressed Corroded Tendons</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20R.%20Elomari">Ibrahim R.

However, it is not generally used on high strength, pre-stressed tendons due to the risk of hydrogen generation, leading to possible embrittlement. This paper investigates its use in such circumstances where the applied protection potential is varied to determine if CP can be safely employed on pre-stressed tendons. Plain steel tendons measuring 5.4 mm diameter were pre-stressed in timber moulds and embedded in sand/cement mortar, formulated to represent gunite. Two levels of pre-stressing were investigated (400MPa and 1200MPa). Pre-corrosion of 0% (control), 3% and 6% target loss of cross-sectional area was applied to replicate service conditions. Impressed current cathodic protection (ICCP) was then applied to the tendons at two levels of potential to identify any effect on strength. Instant-off values up to -950mV were used for normal protection with values of -1100mV or more negative to achieve overprotection. Following the ICCP phase, the tendons were removed from the mortar, cleaned and weighed to confirm actual percentage of corrosion. Tensile tests were then conducted on the tendons. The preliminary results show the influence of normal levels and overprotection of CP on the ultimate strength of the tendons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pre-stressed%20concrete" title="pre-stressed concrete">pre-stressed concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=cathodic%20protection" title=" cathodic protection"> cathodic protection</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20embrittlement" title=" hydrogen embrittlement"> hydrogen embrittlement</a> </p> <a href="https://publications.waset.org/abstracts/79186/influence-of-cathodic-protection-on-high-strength-pre-stressed-corroded-tendons" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79186.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">266</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">688</span> Integrating Process Planning, WMS Dispatching, and WPPW Weighted Due Date Assignment Using a Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Halil%20Ibrahim%20Demir">Halil Ibrahim Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=Tar%C4%B1k%20Cakar"> Tarık Cakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Cil"> Ibrahim Cil</a>, <a href="https://publications.waset.org/abstracts/search?q=Muharrem%20Dugenci"> Muharrem Dugenci</a>, <a href="https://publications.waset.org/abstracts/search?q=Caner%20Erden"> Caner Erden</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conventionally, process planning, scheduling, and due-date assignment functions are performed separately and sequentially. The interdependence of these functions requires integration. Although integrated process planning and scheduling, and scheduling with due date assignment problems are popular research topics, only a few works address the integration of these three functions. This work focuses on the integration of process planning, WMS scheduling, and WPPW due date assignment. Another novelty of this work is the use of a weighted due date assignment. In the literature, due dates are generally assigned without considering the importance of customers. However, in this study, more important customers get closer due dates. Typically, only tardiness is punished, but the JIT philosophy punishes both earliness and tardiness. In this study, all weighted earliness, tardiness, and due date related costs are penalized. As no customer desires distant due dates, such distant due dates should be penalized. In this study, various levels of integration of these three functions are tested and genetic search and random search are compared both with each other and with ordinary solutions. Higher integration levels are superior, while search is always useful. Genetic searches outperformed random searches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=process%20planning" title="process planning">process planning</a>, <a href="https://publications.waset.org/abstracts/search?q=weighted%20scheduling" title=" weighted scheduling"> weighted scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=weighted%20due-date%20assignment" title=" weighted due-date assignment"> weighted due-date assignment</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=random%20search" title=" random search"> random search</a> </p> <a href="https://publications.waset.org/abstracts/51544/integrating-process-planning-wms-dispatching-and-wppw-weighted-due-date-assignment-using-a-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51544.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">394</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">687</span> The Effect of Artificial Intelligence on the Production of Agricultural Lands and Labor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Makram%20Ibrahim%20Salib">Ibrahim Makram Ibrahim Salib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agriculture plays an essential role in providing food for the world's population. It also offers numerous benefits to countries, including non-food products, transportation, and environmental balance. Precision agriculture, which employs advanced tools to monitor variability and manage inputs, can help achieve these benefits. The increasing demand for food security puts pressure on decision-makers to ensure sufficient food production worldwide. To support sustainable agriculture, unmanned aerial vehicles (UAVs) can be utilized to manage farms and increase yields. This paper aims to provide an understanding of UAV usage and its applications in agriculture. The objective is to review the various applications of UAVs in agriculture. Based on a comprehensive review of existing research, it was found that different sensors provide varying analyses for agriculture applications. Therefore, the purpose of the project must be determined before using UAV technology for better data quality and analysis. In conclusion, identifying a suitable sensor and UAV is crucial to gather accurate data and precise analysis when using UAVs in agriculture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture%20land" title="agriculture land">agriculture land</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture%20land%20loss" title=" agriculture land loss"> agriculture land loss</a>, <a href="https://publications.waset.org/abstracts/search?q=Kabul%20city" title=" Kabul city"> Kabul city</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20land%20expansion" title=" urban land expansion"> urban land expansion</a>, <a href="https://publications.waset.org/abstracts/search?q=urbanization%20agriculture%20yield%20growth" title=" urbanization agriculture yield growth"> urbanization agriculture yield growth</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture%20yield%20prediction" title=" agriculture yield prediction"> agriculture yield prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=explorative%20data%20analysis" title=" explorative data analysis"> explorative data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20models" title=" predictive models"> predictive models</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20models%20drone" title=" regression models drone"> regression models drone</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20agriculture" title=" precision agriculture"> precision agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=farmer%20income" title=" farmer income"> farmer income</a> </p> <a href="https://publications.waset.org/abstracts/183735/the-effect-of-artificial-intelligence-on-the-production-of-agricultural-lands-and-labor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183735.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">74</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">686</span> Role of Interlukin-18 in Primary Knee Osteoarthritis: Clinical, Laboratory and Radiological Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Khalil%20Ibrahim">Ibrahim Khalil Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Enas%20Mohamed%20Shahine"> Enas Mohamed Shahine</a>, <a href="https://publications.waset.org/abstracts/search?q=Abeer%20Shawky%20El%20Hadedy"> Abeer Shawky El Hadedy</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba"> Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghada%20Salah%20Attia%20Hussein"> Ghada Salah Attia Hussein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Osteoarthritis (OA) is a multifactorial disease characterized by a progressive degradation of articular cartilage and is the leading cause of disability in elderly persons. IL-18 contributes to the destruction of cartilage and bone in the disease process of arthritis. The aim of the study was to investigate the role of IL-18 in primary knee OA patients. Serum level of IL-18 was assessed by enzyme-linked immunosorbent assay in 30 primary knee OA patients and compared to 20 age and gender-matched healthy volunteers as a control group. Radiographic severity of OA was assessed by Kellgren and Lawrence (KL) global scale. Pain, stiffness and functional assessment were done using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). OA patients had significantly higher serum IL-18 level than in control group (420.93 ± 345.4 versus 151.03 ± 144.16 pg/ml, P=0.001). Serum level of IL-18 was positively correlated with KL global scale (P=0.001). There were no statistically significant correlations between serum level of IL-18 and pain, stiffness, function subscales and total WOMAC index scores among the studied patients. In conclusions, IL-18 has a role in the pathogenesis of OA and it is positively correlated with the radiographic damage of OA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Interlukin-18" title="Interlukin-18">Interlukin-18</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20osteoarthritis" title=" knee osteoarthritis"> knee osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=primary%20osteoarthritis" title=" primary osteoarthritis"> primary osteoarthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=WOMAC%20scale" title=" WOMAC scale"> WOMAC scale</a> </p> <a href="https://publications.waset.org/abstracts/46517/role-of-interlukin-18-in-primary-knee-osteoarthritis-clinical-laboratory-and-radiological-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46517.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">384</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">685</span> Theoretical Study of Structural, Magnetic, and Magneto-Optical Properties of Ultrathin Films of Fe/Cu (001)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mebarek%20Boukelkoul">Mebarek Boukelkoul</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhalim%20Haroun"> Abdelhalim Haroun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> By means of the first principle calculation, we have investigated the structural, magnetic and magneto-optical properties of the ultra-thin films of Fen/Cu(001) with (n=1, 2, 3). We adopted a relativistic approach using DFT theorem with local spin density approximation (LSDA). The electronic structure is performed within the framework of the Spin-Polarized Relativistic (SPR) Linear Muffin-Tin Orbitals (LMTO) with the Atomic Sphere Approximation (ASA) method. During the variational principle, the crystal wave function is expressed as a linear combination of the Bloch sums of the so-called relativistic muffin-tin orbitals centered on the atomic sites. The crystalline structure is calculated after an atomic relaxation process using the optimization of the total energy with respect to the atomic interplane distance. A body-centered tetragonal (BCT) pseudomorphic crystalline structure with a tetragonality ratio c/a larger than unity is found. The magnetic behaviour is characterized by an enhanced magnetic moment and a ferromagnetic interplane coupling. The polar magneto-optical Kerr effect spectra are given over a photon energy range extended to 15eV and the microscopic origin of the most interesting features are interpreted by interband transitions. Unlike thin layers, the anisotropy in the ultra-thin films is characterized by a perpendicular magnetization which is perpendicular to the film plane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrathin%20films" title="ultrathin films">ultrathin films</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetism" title=" magnetism"> magnetism</a>, <a href="https://publications.waset.org/abstracts/search?q=magneto-optics" title=" magneto-optics"> magneto-optics</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomorphic%20structure" title=" pseudomorphic structure"> pseudomorphic structure</a> </p> <a href="https://publications.waset.org/abstracts/25728/theoretical-study-of-structural-magnetic-and-magneto-optical-properties-of-ultrathin-films-of-fecu-001" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25728.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">335</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">684</span> Low Back Pain among Nurses in Penang Public Hospitals: A Study on Prevalence and Factors Associated</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Izani%20Uzair%20Zubair">Izani Uzair Zubair</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Ismail%20Ibrahim"> Mohd Ismail Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Nazri%20Shafei"> Mohd Nazri Shafei</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Merican%20Omar%20Naina%20Merican"> Hassan Merican Omar Naina Merican</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Sabri%20Othman"> Mohamad Sabri Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Izmi%20Ahmad%20Ibrahim"> Mohd Izmi Ahmad Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rasilah%20Ramli"> Rasilah Ramli</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajpal%20Singh%20Karam%20Singh"> Rajpal Singh Karam Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nurses experience a higher prevalence of low back pain (LBP) and musculoskeletal complaints as compared to other hospital workers. Due to no proper policy related to LBP, the job has exposed them to the problem. Thus, the current study aims to look at the intensity of the problem and factors associated with development of LBP. Method and Tools: A cross sectional study was carried out among 1292 nurses from six public hospitals in Penang. They were randomly selected and those who were pregnant and have been diagnosed to have LBP were excluded. A Malay validated BACK Questionnaire was used. The associated factors were determined by using multiple logistic regression from SPSS version 20.0. Result: Most of the respondents were at mean age 30 years old and had mean working experience 86 months. The prevalence of LBP was identified as 76% (95% CI 74, 82). Factors that were associated with LBP among nurses include lifting a heavy object (OR2.626 (95% CI 1.978, 3.486) p =0.001 and the estimation weight of the lifted object (OR1.443 (95% CI 1.056, 1.970) p =0.021. Conclusion: Nurses who practice lifting heavy object and weight of the object lifted give a significant contribution to the development of LBP. The prevalence of the problem is significantly high. Thus, a proper no weight lifting policy should be considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=nurses" title=" nurses"> nurses</a>, <a href="https://publications.waset.org/abstracts/search?q=Penang%20public%20hospital" title=" Penang public hospital"> Penang public hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=Penang" title=" Penang"> Penang</a> </p> <a href="https://publications.waset.org/abstracts/64098/low-back-pain-among-nurses-in-penang-public-hospitals-a-study-on-prevalence-and-factors-associated" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64098.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">487</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">683</span> Evaluation of Digital Assessment of Anal Sphincter Muscle Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Gihan%20Abd%20El-Lateif%20Younis%20El-Tantawi"> Gihan Abd El-Lateif Younis El-Tantawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hamdy%20Zahran"> Mohammed Hamdy Zahran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Khalil%20Ibrahim"> Ibrahim Khalil Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Abd%20El-Salam%20Shehata"> Mohammed Abd El-Salam Shehata</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Al-Moghazy%20Sultan"> Hussein Al-Moghazy Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Medhat%20Mohamed%20Anwar"> Medhat Mohamed Anwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Examination of the external anal sphincter muscle strength of voluntary contraction is essential in initial assessment and assessment of efficacy of rehabilitation of patients with faecal incontinence (FI) and obstructed defecation (OD).

All patients were subjected to history taking, clinical examination including assessment of the external anal sphincter muscle strength of voluntary contraction by using MOS and anal manometry (mean squeeze pressure and maximal squeeze pressure). There was a statistically significant positive correlation between MOS and anal manometry squeeze pressures including mean squeeze pressure and maximal squeeze pressure among FI group and OD group. In conclusion, assessment of the external anal sphincter muscle strength of voluntary contraction by using MOS is a valid method and can substitute anal manometry assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anal%20manometry" title="anal manometry">anal manometry</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20anal%20sphincter%20muscle" title=" external anal sphincter muscle"> external anal sphincter muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=Modified%20Oxford%20Scale" title=" Modified Oxford Scale"> Modified Oxford Scale</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20strength" title=" muscle strength"> muscle strength</a> </p> <a href="https://publications.waset.org/abstracts/32483/evaluation-of-digital-assessment-of-anal-sphincter-muscle-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32483.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">416</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">682</span> Rock Slope Stabilization and Protection for Roads and Multi-Storey Structures in Jabal Omar, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Abdel%20Gadir%20Malik">Ibrahim Abdel Gadir Malik</a>, <a href="https://publications.waset.org/abstracts/search?q=Dafalla%20Siddig%20Dafalla"> Dafalla Siddig Dafalla</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelazim%20Ibrahim"> Abdelazim Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Jabal Omar is located in the western side of Makkah city in Saudi Arabia. The proposed Jabal Omar Development project includes several multi-storey buildings, roads, bridges and below ground structures founded at various depths. In this study, geological mapping and site inspection which covered pre-selected areas were carried out within the easily accessed parts. Geological features; including rock types, structures, degree of weathering, and geotechnical hazards were observed and analyzed with specified software and also were documented in form of photographs. The presence of joints and fractures in the area made the rock blocks small and weak. The site is full of jointing; it was observed that, the northern side consists of 3 to 4 jointing systems with 2 random fractures associated with dykes. The southern part is affected by 2 to 3 jointing systems with minor fault and shear zones. From the field measurements and observations, it was concluded that, the Jabal Omar intruded by andesitic and basaltic dykes of different thickness and orientation. These dykes made the outcrop weak, highly deformed and made the rock masses sensitive to weathering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rock" title="rock">rock</a>, <a href="https://publications.waset.org/abstracts/search?q=slope" title=" slope"> slope</a>, <a href="https://publications.waset.org/abstracts/search?q=stabilization" title=" stabilization"> stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=protection" title=" protection"> protection</a>, <a href="https://publications.waset.org/abstracts/search?q=Makkah" title=" Makkah"> Makkah</a> </p> <a href="https://publications.waset.org/abstracts/32229/rock-slope-stabilization-and-protection-for-roads-and-multi-storey-structures-in-jabal-omar-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32229.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">809</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">681</span> ICT for Smart Appliances: Current Technology and Identification of Future ICT Trend</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abubakar%20Uba%20Ibrahim">Abubakar Uba Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Haruna%20Shanono"> Ibrahim Haruna Shanono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smart metering and demand response are gaining ground in industrial and residential applications. Smart Appliances have been given concern towards achieving Smart home. The success of Smart grid development relies on the successful implementation of Information and Communication Technology (ICT) in power sector. Smart Appliances have been the technology under development and many new contributions to its realization have been reported in the last few years. The role of ICT here is to capture data in real time, thereby allowing bi-directional flow of information/data between producing and utilization point; that lead a way for the attainment of Smart appliances where home appliances can communicate between themselves and provide a self-control (switch on and off) using the signal (information) obtained from the grid. This paper depicts the background on ICT for smart appliances paying a particular attention to the current technology and identifying the future ICT trends for load monitoring through which smart appliances can be achieved to facilitate an efficient smart home system which promote demand response program. This paper grouped and reviewed the recent contributions, in order to establish the current state of the art and trends of the technology, so that the reader can be provided with a comprehensive and insightful review of where ICT for smart appliances stands and is heading to. The paper also presents a brief overview of communication types, and then narrowed the discussion to the load monitoring (Non-intrusive Appliances Load Monitoring ‘NALM’). Finally, some future trends and challenges in the further development of the ICT framework are discussed to motivate future contributions that address open problems and explore new possibilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication%20technology%20between%20appliances" title="communication technology between appliances">communication technology between appliances</a>, <a href="https://publications.waset.org/abstracts/search?q=demand%20response" title=" demand response"> demand response</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20monitoring" title=" load monitoring"> load monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20appliances" title=" smart appliances"> smart appliances</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a> </p> <a href="https://publications.waset.org/abstracts/32985/ict-for-smart-appliances-current-technology-and-identification-of-future-ict-trend" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32985.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">613</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">680</span> Chamba Encroachment into Jukum Territory and Its Impact 1830-1900</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iliya%20Ibrahim%20%20Gimba">Iliya Ibrahim Gimba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The period between the late 18th and early 19th centuries was characterized by conflict of ethnic nationalities in the Benue valley region. This conflict was exacerbated by the introduction of the Fulani jihad that began in Hausa land into the Benue valley region. Fulani in this region launched the Jihad movement which pushed out some ethnic groups from their natural abode or ancestral home to live a nomad live until they could settle and established a stayed in a particular place. The Chamba were being displaced by the Fulani jihad that took place around Faro deo in about 1809. It was from there that most of the Chamba migrated out, some into the Cameroon republic, while others moved into the Benue valley region. Among those that entered into the Benue valley region are the Sama, Kola, Gayam etc, and could be found in Donga local Government area of Taraba state. Those Chamba clan that later on cameo into the Benue Valley are Pyeri, Kashimbila etc. The sudden movement of the Chamba or migrations into the Jukun territory co-in ceded with the period that the Jihad had already had a severe and consequential effect or impact on the Jukun territory cause by Yakubu Ibrahim of Bzuchi, and Buba Yero of Gombe, and Hamaruwa of Muri Emirate. This ne authorities in Kwararafa Kingdom cut the Jukun King out of contact with Borno and Hausa-land. This paper set to examine the chiefdom that the Chamba established right within the Jukun headquarters of Wukari.

The majority of sea ports depend on the national electric grid as a source of power for the domestic and ships’ electric demands. This paper discusses the possibility of shifting ports from relying on the national grid electricity to green power-based ports. Offshore wind turbines and hydrogenic PEM fuel cell units appear as two typical promising clean energy sources for ports. As a case study, the paper investigates the prospect of converting Alexandria Port in Egypt to be an eco-friendly port with the study of technical, logistic, and financial requirements. The results show that the fuel cell, followed by a combined system of wind turbines and fuel cells, is the best choice regarding electricity production unit cost by 0.101 and 0.107 $/kWh, respectively. Furthermore, using of fuel cells and offshore wind turbine as green power concept will achieving emissions reduction quantity of CO₂, NOx, and CO emissions by 80,441, 20.814, and 133.025 ton per year, respectively. Finally, the paper highlights the role that renewable energy can play when supplying Alexandria Port with green energy to lift the burden on the government in supporting the electricity, with a possibility of achieving a profit of 3.85% to 22.31% of the annual electricity cost compared with the international prices. <p class="card-text"><strong>Keywords:</strong> <a
