However, due to the lack of Islamic knowledge it might be very difficult for a layperson to perform it correctly. This paper presents an ontology based representation of Islamic rules to perform Salah. The Salah ontology has been built under the guidance of domain expert in light of Quran and Hadith. The ontology consists of basic concepts as well as relationship among concepts and constraints on them. The basic concepts include cleanness, body cover, Salah timing and steps to perform Salah. The SWRL rule language has been used to represent rule to determine whether the Salah performed correctly or it should be repeated. Finally, we evaluate the use of the Salat ontology through user’s example queries using SPARQL queries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prayer" title="prayer">prayer</a>, <a href="https://publications.waset.org/abstracts/search?q=salah" title=" salah"> salah</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=SPARQL%20queries" title=" SPARQL queries"> SPARQL queries</a>, <a href="https://publications.waset.org/abstracts/search?q=reasoning" title=" reasoning"> reasoning</a> </p> <a href="https://publications.waset.org/abstracts/49552/ontology-based-representation-of-islamic-rules-to-perform-salah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49552.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">418</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">1757</span> Adverse Effects on Liver Function in Male Rats after Exposure to a Mixture of Endocrine Disrupting Pesticides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amine%20Aiche">Mohamed Amine Aiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Elkhansa%20Yahia"> Elkhansa Yahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Mallem"> Leila Mallem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salah%20Boulakoud"> Mohamed Salah Boulakoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exposure to endocrine disrupting (ED) during life may cause long-term health effects, the population is exposed to chemicals present in air, water, food and in a variety of consumer and personal care products. Previous research indicates that a wide range of pesticides may act as endocrine disrupters. The azole fungicides propiconazole and propineb have been shown to react through several endocrine disrupting mechanisms, and to induce various endocrine disrupting effects. The purpose of this study was to evaluate the effects of two fungicides; propiconazole and propineb tested separately and in combination, on liver function. The experimental was applied on male Wistar rats dosed orally with Propiconazole 60 mg/kg/day, Propineb 100 mg/kg/day and their mixture 30 mg Propiconazole/kg/day + 50 mg Propineb /kg/day for 4 weeks, for result, a significant increase in liver weights in both treated groups with propineb, propiconazole and their mixture by reference with controls group. Also, highly significant mean values of markers of liver function such as transaminases (ALT/AST) and the activity of alkaline phosphatase (ALP) in all treated groups. The antioxidant activity showed a significant decrease in the hepatic glutathione content (GSH) and glutathione peroxidase (GPX) in all treated groups. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endocrine%20disrupting" title="endocrine disrupting">endocrine disrupting</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticide%20mixture" title=" pesticide mixture"> pesticide mixture</a>, <a href="https://publications.waset.org/abstracts/search?q=propineb" title=" propineb"> propineb</a>, <a href="https://publications.waset.org/abstracts/search?q=propiconazole" title=" propiconazole"> propiconazole</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/14958/adverse-effects-on-liver-function-in-male-rats-after-exposure-to-a-mixture-of-endocrine-disrupting-pesticides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14958.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">522</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1756</span> Repeated Dose 28-Day Oral Toxicity Study Offungicides: Propinèbe, Propiconazole, And Their Mixture in Wistar Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aiche%20Mohamed%20Amine">Aiche Mohamed Amine</a>, <a href="https://publications.waset.org/abstracts/search?q=Mallem%20Leila"> Mallem Leila</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahia%20El%20Khansa"> Yahia El Khansa</a>, <a href="https://publications.waset.org/abstracts/search?q=Boulakoud%20Mohamed%20Salah"> Boulakoud Mohamed Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Until recently, toxicological studies focused on the effects of individual chemicals.

In this study, we aimed to investigate the possible protective effect of olive oil, an antioxidant agent, against experimental mercury toxicity in rat model. Administration of mercuric chloride induced significant increase in serum: ALT, AST, and LPA activities; interleukine1, interleukine6, tumor necrosis factor α (TNFα), creatinine, urea, and uric acid levels. Mercuric chloride also induced oxidative stress, as indicate by decreased tissue of GSH level, GSH-Px, and GST activities along with increase the level of lipid peroxidation. Furthermore, treatment with mercuric chloride caused a marked elevation of kidney and liver weight and decreased body weight. Virgin olive oil treatment markedly reduced elevated serum: AST, ALT, and LPA activities; interleukine1, interleukine6, tumor necrosis factor α (TNFα), creatinine, urea, and uric acid levels and contracted the deterious effects of mercuric chloride on oxidative stress markers changes caused by HgCl2 in tissue as compared to control group. Our results implicate that mercury induced oxidative damage in liver and kidney tissue protected by virgin olive oil, with its antioxidant effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mercury" title="mercury">mercury</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzymes" title=" antioxidant enzymes"> antioxidant enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=pro-inflammatory%20cytokine" title=" pro-inflammatory cytokine"> pro-inflammatory cytokine</a>, <a href="https://publications.waset.org/abstracts/search?q=virgin%20olive%20oil" title=" virgin olive oil"> virgin olive oil</a>, <a href="https://publications.waset.org/abstracts/search?q=lipid%20peroxidation" title=" lipid peroxidation"> lipid peroxidation</a> </p> <a href="https://publications.waset.org/abstracts/4443/olive-oil-olea-europea-l-protects-against-mercury-ii-induced-oxidative-tissue-damage-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4443.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">361</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">1753</span> Combined Cervical Headache Snag with Cervical Snag Half Rotation Techniques on Cervicogenic Headache Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wael%20Salah%20Shendy">Wael Salah Shendy</a>, <a href="https://publications.waset.org/abstracts/search?q=Moataz%20Mohamed%20EL%20Semary"> Moataz Mohamed EL Semary</a>, <a href="https://publications.waset.org/abstracts/search?q=Hosam%20Salah%20Murad"> Hosam Salah Murad</a>, <a href="https://publications.waset.org/abstracts/search?q=Adham%20A.%20Mohamed"> Adham A.

Objectives: To determine the effect of C1-C2 Mulligan SNAGs mobilizations on cervicogenic headache and associated dizziness symptoms. Methods: Forty-eight patients with cervicogenic headache included in the study; from the outpatient clinic of Faculty of Physical Therapy, Cairo University, and New Cairo outpatient clinics, were randomly assigned into three equal groups; group A ( Headache SNAG), group B (C1-C2 SNAG rotation) and group C (combined). Their mean age was (29.37 ± 2.6), (29.31 ± 2.54) and (29.68 ± 2.65). Neck Disability Index used to examine neck pain intensity and CEH symptoms. 6 Items Headache Impact test '6-HIT' scale used to examine headache severity and its adverse effects on social life and functions. Flexion-Rotation Test 'FRT' also used to assess rotation ROM at the level of C1-C2 by 'CROM' device. Dizziness Handicap Inventory 'DHI' scale was used to evaluate dizziness symptoms. Evaluation is done pre and post treatment, and comparison between groups was quantified. Correlations between the examined parameters were also measured. Headache SNAG and C1-C2 Rotation SNAGs were done separately in group (A- B) and combined in group C as a treatment intervention. Results: Group C has Significant improvement in whole parameters compared to group A and B, positive correlation was found between NDI and 6-HIT scores compared to negative correlation between NDI and DHI scores. Conclusion: SNAGs mobilizations used in the study were effective in reducing cervicogenic headache and dizziness symptoms in all groups with a noticeable improvement in the combined group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cervicogenic%20headache" title="cervicogenic headache">cervicogenic headache</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20headache%20snag" title=" cervical headache snag"> cervical headache snag</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20snag%20half%20rotation" title=" cervical snag half rotation"> cervical snag half rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=cervical%20dizziness" title=" cervical dizziness"> cervical dizziness</a> </p> <a href="https://publications.waset.org/abstracts/90197/combined-cervical-headache-snag-with-cervical-snag-half-rotation-techniques-on-cervicogenic-headache-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90197.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">197</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">1752</span> A Novel Parametric Chaos-Based Switching System PCSS for Image Encryption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salah%20Azzaz">Mohamed Salah Azzaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Camel%20Tanougast"> Camel Tanougast</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Hadjem"> Tarek Hadjem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a new low-cost image encryption technique is proposed and analyzed.

By cons when these materials are mixed, their behavior will become different from each considered alone. The behavior of these mixtures (silty sands etc.) is currently the state of several studies to better use. We studied in this work: The influence of the following factors on the shear strength: (The density, the fines content, the water content).

The precursor aqueous bath contained 1 mole of lead nitrate, 1 mole of Thiourea and complexing agents (triethanolamine (TEA) and NaOH). Bath temperature and deposition time were fixed at 60°C and 3 hours, respectively. However, the PH of bath was varied from 10.5 to 12.5. Structural properties of the deposited films were characterized by X-ray diffraction and Raman spectroscopy. The preferred direction was revealed to be along (111) and the PbS crystal structure was confirmed. Strains and grains sizes were also calculated. Optical studies showed that films thicknesses do not exceed 600nm. Energy band gap values of films decreases with increase in pH and reached a value ~ 0.4eV at pH equal 12.5. The small value of the energy band gap makes PbS one of the most interesting candidate for solar energy conversion near the infrared ray. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CBD" title="CBD">CBD</a>, <a href="https://publications.waset.org/abstracts/search?q=PbS" title=" PbS"> PbS</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</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=x-ray%20diffraction" title=" x-ray diffraction"> x-ray diffraction</a> </p> <a href="https://publications.waset.org/abstracts/29510/structural-optical-and-electrical-properties-of-pbs-thin-films-deposited-by-cbd-at-different-bath-ph" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29510.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">1747</span> Anterior Segment Optical Coherence Tomography Study of Cornea and Tear Film Parameters in Juvenile Systemic Lupus Erythematous Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salah%20El-Din%20Mahmoud">Mohamed Salah El-Din Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hamed"> Ahmed Hamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Anwar%20Mohamed"> Asmaa Anwar Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: To study the tear film parameters, total corneal thickness (CT), corneal epithelial thickness and, corneal power in Juvenile systemic lupus erythematosus (JSLE) patients compared to age-matched controls using anterior segment optical coherence tomography (AS-OCT). Methods: This was a cross-sectional study. Study participants were divided into 2 groups: Group A: 75 eyes of JSLE patients, Group B: 75 eyes of healthy controls. Tear meniscus height (TMH), tear meniscus depth (TMD), and tear meniscus area (TMA) were the lower tear meniscus parameters that were measured. The corneal power, CT, and epithelial thickness were all determined automatically. Results: In the JSLE group, the range of age was 10 to 15 years while the control group was 11 to 16 years. TMH, TMA, and TMD were 527.7±46.8, 0.059±0.015 and 343.3±59.9 respectively in JSLE group while 525.4±44.6, 0.058±0.011 and 340.6±58.0 respectively in control group without significant difference (p-value<0.001). The corneal power was 43.3±0.55 in the JSLE while 43.2±0.54 in the control group without significant difference (p-value= 0.407). CT was 551.1±13.5 in JSLE group while 551.2±15.3 in control group without significant difference (p-value= 0.982). Epithelial thickness was 52.66±1.35 in the JSLE group while 52.60±1.36 in the control group without significant difference (p-value= 0.765). Conclusion: We demonstrated no significant difference in tear meniscus dimensions, CT, epithelial thickness, and corneal power in the JSLE patients compared to age-matched controls using AS-OCT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tear%20film" title="tear film">tear film</a>, <a href="https://publications.waset.org/abstracts/search?q=ASOCT" title=" ASOCT"> ASOCT</a>, <a href="https://publications.waset.org/abstracts/search?q=JSLE" title=" JSLE"> JSLE</a>, <a href="https://publications.waset.org/abstracts/search?q=pachymetry" title=" pachymetry"> pachymetry</a>, <a href="https://publications.waset.org/abstracts/search?q=corneal%20thickness" title=" corneal thickness"> corneal thickness</a> </p> <a href="https://publications.waset.org/abstracts/143829/anterior-segment-optical-coherence-tomography-study-of-cornea-and-tear-film-parameters-in-juvenile-systemic-lupus-erythematous-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143829.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">172</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">1746</span> Rejuvenate: Face and Body Retouching Using Image Inpainting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossam%20Abdelrahman">Hossam Abdelrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Sama%20Rostom"> Sama Rostom</a>, <a href="https://publications.waset.org/abstracts/search?q=Reem%20Yassein"> Reem Yassein</a>, <a href="https://publications.waset.org/abstracts/search?q=Yara%20Mohamed"> Yara Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Salma%20Salah"> Salma Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour%20Awny"> Nour Awny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In today’s environment, people are becoming increasingly interested in their appearance. However, they are afraid of their unknown appearance after a plastic surgery or treatment. 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. The system uses the input of the user of an image to indicate a problem, the system will then modify the image and output the fixed image, facilitating for the patient to see the final result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=generative%20adversarial%20network" title="generative adversarial network">generative adversarial network</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20mask%20inpainting" title=" large mask inpainting"> large mask inpainting</a>, <a href="https://publications.waset.org/abstracts/search?q=stable%20diffusion%20inpainting" title=" stable diffusion inpainting"> stable diffusion inpainting</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20surgery" title=" plastic surgery"> plastic surgery</a> </p> <a href="https://publications.waset.org/abstracts/171208/rejuvenate-face-and-body-retouching-using-image-inpainting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171208.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">1745</span> The Influence of the Form of Grain on the Mechanical Behaviour of Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Boualem%20Salah">Mohamed Boualem Salah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The size and shape of soil particles reflect the formation history of the grains. In turn, the macro scale behavior of the soil mass results from particle level interactions which are affected by particle shape. Sphericity, roundness and smoothness characterize different scales associated to particle shape. New experimental data and data from previously published studies are gathered into two databases to explore the effects of particle shape on packing as well as small and large-strain properties of sandy soils. Data analysis shows that increased particle irregularity (angularity and/or eccentricity) leads to: an increase in emax and emin, a decrease in stiffness yet with increased sensitivity to the state of stress, an increase in compressibility under zero-lateral strain loading, and an increase in critical state friction angle φcs and intercept Γ with a weak effect on slope λ. Therefore, particle shape emerges as a significant soil index property that needs to be properly characterized and documented, particularly in clean sands and gravels. The systematic assessment of particle shape will lead to a better understanding of sand behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angularity" title="angularity">angularity</a>, <a href="https://publications.waset.org/abstracts/search?q=eccentricity" title=" eccentricity"> eccentricity</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20%20particle" title=" shape particle"> shape particle</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior%20of%20soil" title=" behavior of soil"> behavior of soil</a> </p> <a href="https://publications.waset.org/abstracts/17611/the-influence-of-the-form-of-grain-on-the-mechanical-behaviour-of-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17611.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">414</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">1744</span> Consumers Rights during COVID-19 Pandemic Time: Evidence from Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabri%20Gabran%20Mohammed%20Elkrghli">Sabri Gabran Mohammed Elkrghli</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah%20A.%20Mohamed%20Abdulgader"> Salah A.

Libyan consumers have been targeted in this study with the aim to measure their attitudes towards the extent to which their rights, as consumers of foodstuff, have been secured during the Covid-19 pandemic. The recommended sample size was randomly selected (384) local participants. Out of this number, only a validated number of (267) responses were deemed valid for the analysis phase. The instrument of this research was developed based on the extant published literature on consumer rights. The study concluded with a set of key results; the most important result is that consumer rights of foodstuffs were below the satisfactory level. Theoretical and practical implications have emerged from the study. The most important implication is that customers of foodstuffs need more protection in Libya. This issue should be given greater importance, especially in the light of contemporary environmental challenges such as the outbreak of Covid-19. Designing and conducting global and local awareness campaigns is another significant advice suggested by this study.

This division has to be made in a methodical way. In this paper, we introduce an industrial control system modeling and simulation based on the Multi-Agent System (MAS) methodology AALAADIN and more particularly the underlying conceptual model Agent/Group/Role (AGR). Indeed, in this division using AGR model, the overall system is decomposed into sub-systems in order to improve the understanding of regulation and control systems, and to simplify the implementation of the obtained agents and their groups, which are implemented using the Multi-Agents Development KIT (MAD-KIT) platform. This approach appears to us to be the most appropriate for modeling of this type of systems because, due to the use of MAS, it is possible to model real systems in which very complex behaviors emerge from relatively simple and local interactions between many different individuals, therefore a MAS is well adapted to describe a system from the standpoint of the activity of its components, that is to say when the behavior of the individuals is complex (difficult to describe with equations). The main aim of this approach is the take advantage of the performance, the scalability and the robustness that are intuitively provided by MAS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20systems" title="complex systems">complex systems</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20and%20simulation" title=" modeling and simulation"> modeling and simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20control%20system" title=" industrial control system"> industrial control system</a>, <a href="https://publications.waset.org/abstracts/search?q=MAS" title=" MAS"> MAS</a>, <a href="https://publications.waset.org/abstracts/search?q=AALAADIN" title=" AALAADIN"> AALAADIN</a>, <a href="https://publications.waset.org/abstracts/search?q=AGR" title=" AGR"> AGR</a>, <a href="https://publications.waset.org/abstracts/search?q=MAD-KIT" title=" MAD-KIT"> MAD-KIT</a> </p> <a href="https://publications.waset.org/abstracts/77295/agentgrouprole-organizational-model-to-simulate-an-industrial-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77295.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">240</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">1742</span> Synthesis, Characterization, Computational Study, Antimicrobial Evaluation, in Vivo Toxicity Study of Manganese (II) and Copper (II) Complexes with Derivative Sulfa-drug</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afaf%20Bouchoucha">Afaf Bouchoucha</a>, <a href="https://publications.waset.org/abstracts/search?q=Karima%20Si%20Larbi"> Karima Si Larbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amine%20Bourouaia"> Mohamed Amine Bourouaia</a>, <a href="https://publications.waset.org/abstracts/search?q=Salah.Boulanouar"> Salah.Boulanouar</a>, <a href="https://publications.waset.org/abstracts/search?q=Safia.Djabbar"> Safia.Djabbar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The synthesis, characterization and comparative biological study of manganese (II) and copper (II) complexes with an heterocyclic ligand used in pharmaceutical field (Scheme 1), were reported.

This relation is tested by using two models. The first is used for testing this relation directly by regressing firm specific estimates of cost of equity capital on market beta, firm size and a measure of disclosure level. The second model is used for testing this relation by introducing information asymmetry as mediator variable. This model is suggested by Baron and Kenny (1986) to demonstrate the role of mediator variable in general. Based on a sample of 21 non-financial Tunisian’s listed firms over a period from 2000 to 2004, the results prove that greater disclosure is associated with a lower cost of equity capital. However, the results of indirect relationship indicate a significant positive association between the level of voluntary disclosure and information asymmetry and a significant negative association between information asymmetry and cost of equity capital in contradiction with our previsions. Perhaps this result is due to the biases of measure of information asymmetry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cost%20of%20equity%20capital" title="cost of equity capital">cost of equity capital</a>, <a href="https://publications.waset.org/abstracts/search?q=voluntary%20disclosure" title=" voluntary disclosure"> voluntary disclosure</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20asymmetry" title=" information asymmetry"> information asymmetry</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20Tunisian%E2%80%99s%20listed%20non-financial%20firms" title=" and Tunisian’s listed non-financial firms"> and Tunisian’s listed non-financial firms</a> </p> <a href="https://publications.waset.org/abstracts/19862/the-impact-of-voluntary-disclosure-level-on-the-cost-of-equity-capital-in-tunisians-listed-firms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19862.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">517</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">1740</span> Acute Respiratory Distress Syndrome (ARDS) Developed Clinical Pathway: Suggested Protocol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Salah">Maha Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanaa%20Hashem"> Hanaa Hashem</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20M.%20Alsagheir"> Mahmoud M.

The severity of the clinical course, the uncertainty of the outcome, and the reliance on the full spectrum of critical care resources for treatment mean that the entire health care team is challenged. Researchers and clinicians have investigated the nature of the pathological process and explored treatment options with the goal of improving outcome. Through this application of research to practice, we know that some previous strategies have been ineffective, and innovations in mechanical ventilation, sedation, nutrition, and pharmacological intervention remain important research initiatives. Developed Clinical pathway is multidisciplinary plans of best clinical practice for this specified groups of patients that aid in the coordination and delivery of high quality care. They are a documented sequence of clinical interventions that help a patient to move, progressively through a clinical experience to a desired outcome. Although there is a lot of heterogeneity in patients with ARDS, this suggested developed clinical pathway with alternatives was built depended on a lot of researches and evidence based medicine and nursing practices which may be helping these patients to improve outcomes, quality of life and decrease mortality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20respiratory%20distress%20syndrome%20%28ARDS%29" title="acute respiratory distress syndrome (ARDS)">acute respiratory distress syndrome (ARDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20pathway" title=" clinical pathway"> clinical pathway</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20syndrome" title=" clinical syndrome "> clinical syndrome </a> </p> <a href="https://publications.waset.org/abstracts/29315/acute-respiratory-distress-syndrome-ards-developed-clinical-pathway-suggested-protocol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29315.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">534</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">1739</span> Sudan’s Approach to Knowledge Management in Disaster Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdalla%20Elamein%20Boshara">Mohamed Abdalla Elamein Boshara</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Charles%20Woods"> Peter Charles Woods</a>, <a href="https://publications.waset.org/abstracts/search?q=Nour%20Eldin%20Mohamed%20Elshaiekh"> Nour Eldin Mohamed Elshaiekh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Knowledge Management has become very important for Disaster Management response and planning.

It's a dominant and economically important species widely distributed in the Bou-Hedma National Park, Tunisia. Reintroduction and expansion of T. teneriffae depend solely on sexual reproduction. This makes the understanding of its germination requirements vital for conservation and management. To provide basic information for its conservation and reintroduction, we studied the influence of environmental factors on seed germination patterns. The germination responses of seeds were determined over a wide range of constant temperatures (15–35°C), polyethylene glycol solutions of different osmotic potentials (0 to −2 MPa) and salt solution (0 to 150 mM of NaCl). Results indicated that the optimum temperature germination was attained at 25°C which corresponds to temperatures prevailing during mid spring season in the Mediterranean area. Seeds germinated in Polyethylene Glycol solutions exhibited significantly lower germination than control especially when water potential fell below -0.6 MPa. Germination percentage and rate decreased with an increase NaCl concentration. Seeds germination was substantially delayed and reduced with an increase in NaCl to levels above 50 mM. T. teneriffae is moderately salt tolerant at germination stage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=germination" title="germination">germination</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=Tricholaena%20teneriffae%20L." title=" Tricholaena teneriffae L."> Tricholaena teneriffae L.</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20stress" title=" salt stress"> salt stress</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20stress" title=" water stress"> water stress</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/22742/germination-behavior-of-tricholaena-teneriffae-l-a-perennial-grass-species" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22742.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">293</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">1737</span> Prone Positioning and Clinical Outcomes of Mechanically Ventilated Patients with Severe Acute Respiratory Distress Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20Salah%20Abdullah%20Ismail">Maha Salah Abdullah Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20M.%20Alsagheir"> Mahmoud M.

Lung-protective ventilation is still the key of better outcome in ARDS. Prone position reduces the trans-pulmonary pressure gradient, recruiting collapsed regions of the lung without increasing airway pressure or hyperinflation. Prone ventilation showed improved oxygenation and improved outcomes in severe hypoxemic patients with ARDS. This study evaluates the effect of prone positioning on mechanically ventilated patients with ARDS. A quasi-experimental design was carried out at Critical Care Units, on 60 patients. Two tools were utilized to collect data; Socio demographic, medical and clinical outcomes data sheet. Results of the present study indicated that prone position improves oxygenation in patients with severe respiratory distress syndrome. The study recommended that use prone position in patients with severe ARDS, as early as possible and for long sessions. Also, replication of this study on larger probability sample at the different geographical location is highly recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20respiratory%20distress%20syndrome" title="acute respiratory distress syndrome">acute respiratory distress syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20care" title=" critical care"> critical care</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20ventilation" title=" mechanical ventilation"> mechanical ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=prone%20position" title=" prone position"> prone position</a> </p> <a href="https://publications.waset.org/abstracts/29401/prone-positioning-and-clinical-outcomes-of-mechanically-ventilated-patients-with-severe-acute-respiratory-distress-syndrome" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29401.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">538</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">1736</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">385</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">1735</span> Isolation and Molecular Identification of Two Fungal Strains Capable of Degrading hydrocarbon Contaminants on Saudi Arabian Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amr%20A.%20EL%20Hanafy">Amr A.

The MEP is related to the electronic density and is a very useful descriptor in understanding sites for electrophilic attack and nucleophilic reactions as well as hydrogen bonding interactions. First, geometry optimization was carried out using Hartree–Fock (HF) and DFT methods with 6-311G(d,p) basis set. In order to get more information on the molecule, its stability has been analyzed by natural bond orbital (NBO) analysis. Mulliken population analyses have been calculated. Finally, the molecular electrostatic potential (MEP) and HOMO-LUMO energy levels have been performed. The calculated HOMO and LUMO energies show also the charge transfer within the molecule. The energy gap obtained is about 4 eV which explain the stability of the studied compound. The obtained molecular electrostatic potential from the two methods confirms the nature of the electron charge transfer at the molecular shell and locate the electropositive part and the electronegative part in molecular scale of the title compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=ab%20initio" title=" ab initio"> ab initio</a>, <a href="https://publications.waset.org/abstracts/search?q=HOMO-LUMO" title=" HOMO-LUMO"> HOMO-LUMO</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20compounds" title=" organic compounds"> organic compounds</a> </p> <a href="https://publications.waset.org/abstracts/43840/molecular-electrostatic-potential-in-z-3n2-ethoxyphenyl-2-n2-ethoxyphenyl-imino-thiazolidin-4-one-molecule-by-ab-initio-and-dft-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43840.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">536</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">1733</span> Experimental Study on Friction Factor of Oscillating Flow Through a Regenerator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sa%C3%AFd%20Kahaleras">Mohamed Saïd Kahaleras</a>, <a href="https://publications.waset.org/abstracts/search?q=Fran%C3%A7ois%20Lanzetta"> François Lanzetta</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Khan"> Mohamed Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Guillaume%20Layes"> Guillaume Layes</a>, <a href="https://publications.waset.org/abstracts/search?q=Philippe%20Nika"> Philippe Nika</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an experimental work to characterize the dynamic operation of a metal regenerator crossed by dry compressible air alternating flow.

The manufacture of fertilizers is generally at a high temperature and high pressure, in the presence of several highly hazardous chemicals, dust and gases. These products are absorbed high in the airway, increasing the airway resistance thereby adversely affecting the pulmonary functions of workers. A study was conducted on 34 employees, especially exposed to nitrate derivatives. A questionnaire was prepared and distributed to all employees in the unit. The workers were divided into two groups according to age. Several hormonal parameters Assay were measured. The results of the questionnaire have detected a fertility problem, Concerning the hormones a significant reduction in the concentration of testosterone in both groups and LH in the group aged 30 to 40 year were noted compared to the control. However, an increase in the concentration of prolactin in both groups compared to the control. There was a significant decrease in FSH in the group aged 30 to 40 always in compared with the control group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fertilizers" title="fertilizers">fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20worker" title=" healthy worker"> healthy worker</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=fertility" title=" fertility"> fertility</a> </p> <a href="https://publications.waset.org/abstracts/16066/the-effects-of-fertilizer-in-the-workplace-on-male-infertility-about-workers-of-unit-npk-in-complex-fertial-annaba" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16066.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">399</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">1730</span> Study and Melanocyte Adrenocorticotropic Effects on Sugar Metabolism and Immune Response in Rabbits Oryctolagus cuniculus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Bouaouiche">A.

Melatonin is the main neuro-hormone expressing this operation. It is synthesized in the pinealocytes after conversion serotonin via N-acetyl-transferase enzyme, itself subject to a photoperiodic modulation (activation dark inhibition by light). Some authors have suggested that melatonin is involved in diabetic disease and found that it could have a diabetogenic effect. To this study the effect of this hormone on glucose metabolism has long been subject to controversy. Agreeing in effect and hyperinsulinemic hypoglycemic effect. In order to illustrate the level of interaction of melatonin with neuro-immune- corticotropin axis and its impact on carbohydrate metabolism, we studied the impact homeostatic (glucose) through the solicitation of two control systems (gland pineal and corticotropin axis). We then found that melatonin could have an indirect influence on insulin control (glucose metabolism) to the levels of the growth hormone axis (somatostatin) and adrenocorticotropic (corticotropin). In addition, we have suggested that melatonin might limit the hyperglycemic action of corticosteroids by direct action at peripheral level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pin%C3%A9al%20gland" title="pinéal gland">pinéal gland</a>, <a href="https://publications.waset.org/abstracts/search?q=melatonin" title=" melatonin"> melatonin</a>, <a href="https://publications.waset.org/abstracts/search?q=neuro-immuno-corticotrop" title=" neuro-immuno-corticotrop"> neuro-immuno-corticotrop</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolism" title=" metabolism "> metabolism </a> </p> <a href="https://publications.waset.org/abstracts/23778/study-and-melanocyte-adrenocorticotropic-effects-on-sugar-metabolism-and-immune-response-in-rabbits-oryctolagus-cuniculus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23778.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">476</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">1729</span> Static Relaxation of Glass Fiber Reinforced Pipes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Y.%20Abdellah">Mohammed Y.
