In this situation, the only possible test for an approximate theoretical solution is to compare with data generated from a computer simulation. In this paper, Monte Carlo tools are used to study and compare the elementary particles models. All the experiments are implemented using 10000 events, and the simulated energy is 13 TeV. The mean and the curves of several variables are calculated for each model using MadAnalysis 5. Anomalies in the results can be seen in the muons masses of the minimal supersymmetric standard model and the two Higgs doublet model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feynman%20rules" title="Feynman rules">Feynman rules</a>, <a href="https://publications.waset.org/abstracts/search?q=hadrons" title=" hadrons"> hadrons</a>, <a href="https://publications.waset.org/abstracts/search?q=Lagrangian" title=" Lagrangian"> Lagrangian</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo" title=" Monte Carlo"> Monte Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/63496/simulation-of-the-large-hadrons-collisions-using-monte-carlo-tools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63496.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">319</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Comparison between XGBoost, LightGBM and CatBoost Using a Home Credit Dataset</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Essam%20Al%20Daoud">Essam Al Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gradient boosting methods have been proven to be a very important strategy.

Oto-nephrotxicity is an important and dose - limiting side effect of cis - platin therapy. Nowadays, more attention had been paid to oto-toxicity caused with cis-platin. Aim of the Work: This study was designed to investigate the potential protective effect of Whey protein (WP) against cis-platin induced ototoxicity compared to the effect of N-acetylcysteine (NAC) in rats. Methodology: Male albino rats were randomly divided into 6 groups: untreated rats (control), rats orally treated with whey protein (1g/kg b.w/day) for seven executive days, rats treated orally with N-acetylcysteine (500 mg/kgb.w /day) for seven executive days, rates intoxicated intraperitoneal (ip) with cis- platin (10 mg/kgb.w. once), rats treated with whey protein (1g/kgb.w./day) for seven executive days) followed by one injection (ip) of cis-platin(10 mg/kg b.w.) one hour after the last oral administration of whey protein, rats treated with N- acetylcysteine (for seven executive days followed by one injection (ip) of cis-platin (10 mg/kgb.w) one hour after the last oral administration of N-acetylcysteine. The organ of Corti, the stria vascularis and spiral ganglia were visualized by light microscopy at different magnifications. Results: Cis-platin intoxicated animals showed a significant decrease in serum level of total antioxidant capacity (TAC),with inhibition in the activity of serum glutathione-s transferase(GST) and paraoxonnase-1 (PON-1) in comparison with control. Group treated with either NAC or WP with cis-platin showed significant elevation in the activity of both GST & PON-1 with increased serum level of TAC when compared with cis-platin intoxicated rats. Animals treated with NAC or WP with cis-platin compared to those treated with cis-platin alone showed marked degree of improvement towards control rats as there was significant drop in the serum level of cortecosterone, nitric oxide (NO), and melandialdehyde (MDA).Histopathologic, in NAC pretreated group there was no changes in stria vascularis or spiral ganglia. In group pretreated with WP, there was no histopathologic alteration detected in the organ of Corti and Reissers membrane but oedema and haemorrhage were founded in the stria vascularis in small focal manner. Conclusion: Our finding showed that Whey protein is a natural dietary supplement product proved its ability of protection of anti-oxidant system and the cochlea against cis-platin induced ototoxicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-oxidant" title="anti-oxidant">anti-oxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=cis-platin" title=" cis-platin"> cis-platin</a>, <a href="https://publications.waset.org/abstracts/search?q=N-acetylcysteine" title=" N-acetylcysteine"> N-acetylcysteine</a>, <a href="https://publications.waset.org/abstracts/search?q=ototoxicity" title=" ototoxicity"> ototoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=whey%20protein" title=" whey protein "> whey protein </a> </p> <a href="https://publications.waset.org/abstracts/29781/whey-protein-a-noval-protective-agent-against-oto-toxicity-induced-by-cis-platin-in-male-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29781.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">523</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Vitamin D and Prevention of Rickets in Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mousa%20Saleh%20Daoud">Mousa Saleh Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rickets is a condition that affects the development of bones in children. It causes soft bones, which can become bowed or curved, this bending and curvature is evident in the age of Walking. The most common cause of rickets is dietary deficiency of vitamin D or Lack of exposure to sunlight or both together. The link between vitamin D and rickets has been known for many years and is well understood by doctors and scientists. If a child does not get enough of the vitamin D, the bones cannot form hard outer shells. This is why they become soft and weak. This study was conducted on children who reviewed by our medical clinic between the years 2011-2013. The study included 400 children, aged between one and six years. 11 children had clear clinical manifestations of rickets of varying degrees and all of them due to lack of vitamin D except for one case of rickets resistant to vitamin D. 389 cases ranged between natural and deficiency in vitamin D without clinical manifestations of Rickets. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rickts" title="rickts">rickts</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20metabolic%20diseases" title=" bone metabolic diseases"> bone metabolic diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D" title=" vitamin D"> vitamin D</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a> </p> <a href="https://publications.waset.org/abstracts/39361/vitamin-d-and-prevention-of-rickets-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39361.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">28</span> Simulation and Experimental of Solid Mixing of Free Flowing Material Using Solid Works in V-Blender</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Bouhaouche">Amina Bouhaouche</a>, <a href="https://publications.waset.org/abstracts/search?q=Zineb%20Kaoua"> Zineb Kaoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Lila%20Lahreche"> Lila Lahreche</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Ali%20Kaoua"> Sid Ali Kaoua</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Daoud"> Kamel Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to present a novel approach for analyzing the solid dispersion and mixing performance by a numerical simulation method using solid works software of a monodisperse particles for a large span of time reached 20 minutes.

The chemical fractionation method was used for the speciation study (different forms) of micronutrients in these soils. The results show that total form quantities of cations are height than norms in agricultural soils, thus the quantities of anion are lows. At the other hand, the quantities of available forms are lows. Statistical analysis reveals that cationic micronutrients localize preferentially in the coarse fraction of the soil in salty conditions and that sodicity causes a decrease in the iron reserve in the soil. The pH range ‘7.49 - 8.76’ represents a constraint for the complexation of micronutrients by organic matter. The study concluded that quantities of total and available forms of micronutrients in salty soils are influenced by soil properties such as: pH, electrical conductivity and exchangeable sodium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20fractionation" title="chemical fractionation">chemical fractionation</a>, <a href="https://publications.waset.org/abstracts/search?q=micronutrients" title=" micronutrients"> micronutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=salty%20soils" title=" salty soils"> salty soils</a>, <a href="https://publications.waset.org/abstracts/search?q=speciation" title=" speciation"> speciation</a> </p> <a href="https://publications.waset.org/abstracts/92470/evaluation-of-the-behavior-of-micronutrients-in-salty-soils-of-low-cheliff" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92470.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">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> An Improved Ant Colony Algorithm for Genome Rearrangements</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Essam%20Al%20Daoud">Essam Al Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Genome rearrangement is an important area in computational biology and bioinformatics. The basic problem in genome rearrangements is to compute the edit distance, i.e., the minimum number of operations needed to transform one genome into another. Unfortunately, unsigned genome rearrangement problem is NP-hard. In this study an improved ant colony optimization algorithm to approximate the edit distance is proposed. The main idea is to convert the unsigned permutation to signed permutation and evaluate the ants by using Kaplan algorithm. Two new operations are added to the standard ant colony algorithm: Replacing the worst ants by re-sampling the ants from a new probability distribution and applying the crossover operations on the best ants. The proposed algorithm is tested and compared with the improved breakpoint reversal sort algorithm by using three datasets. The results indicate that the proposed algorithm achieves better accuracy ratio than the previous methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ant%20colony%20algorithm" title="ant colony algorithm">ant colony algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=edit%20distance" title=" edit distance"> edit distance</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%0D%0Abreakpoint" title=" genome breakpoint"> genome breakpoint</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20rearrangement" title=" genome rearrangement"> genome rearrangement</a>, <a href="https://publications.waset.org/abstracts/search?q=reversal%20sort" title=" reversal sort"> reversal sort</a> </p> <a href="https://publications.waset.org/abstracts/5601/an-improved-ant-colony-algorithm-for-genome-rearrangements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5601.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">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Some Probiotic Traits of Lactobacillus Strains Isolated from Pollen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hani%20Belhadj">Hani Belhadj</a>, <a href="https://publications.waset.org/abstracts/search?q=Daoud%20Harzallah"> Daoud Harzallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Seddik%20Khennouf"> Seddik Khennouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Saliha%20Dahamna"> Saliha Dahamna</a>, <a href="https://publications.waset.org/abstracts/search?q=Mouloud%20Ghadbane"> Mouloud Ghadbane </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, Lactobacillus strains isolated from pollen were identiﬁed by means of phenotypic and genotypic methods, At pH 2, most strains proved to be acid resistants, with losses in cell viability ranging from 0.77 to 4.04 Log orders. In addition, at pH 3 all strains could grew and resist the acidic conditions, with losses in cell viability ranging from 0.40 to 3.61 Log orders. It seems that, 0.3% and 0.5% of bile salts does not affect greatly the survival of most strains, excluding Lactobacillus sp. BH1398. Survival ranged from 81.0±3.5 to 93.5±3.9%. In contrast, in the presence of 1.0% bile salts, survival of five strains was decreased by more than 50%. Lactobacillus fermentum BH1509 was considered the most tolerant strain (77.5% for 1% bile) followed by Lactobacillus plantarum BH1541 (59.9% for 1% bile). Furthermore, all strains were resistant to colistine, clindamycine, chloramphenicol, and ciprofloxacine, but most of the strains were susceptible to Peniciline, Oxacillin, Oxytetracyclin, and Amoxicillin. Functionally interesting Lactobacillus isolates may be used in the future as probiotic cultures for manufacturing fermented foods and as bioactive delivery systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=probiotics" title="probiotics">probiotics</a>, <a href="https://publications.waset.org/abstracts/search?q=lactobacillus" title=" lactobacillus"> lactobacillus</a>, <a href="https://publications.waset.org/abstracts/search?q=pollen" title=" pollen"> pollen</a>, <a href="https://publications.waset.org/abstracts/search?q=bile" title=" bile"> bile</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20tolerance" title=" acid tolerance"> acid tolerance</a> </p> <a href="https://publications.waset.org/abstracts/14064/some-probiotic-traits-of-lactobacillus-strains-isolated-from-pollen" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14064.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">420</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Numerical Study of Heat Transfer Nanofluid TiO₂ through a Solar Flat Plate Collector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Maouassi">A.

Stir followed by squeeze casting techniques are used to produce A359 composites. It was noticed that, A359/AlN composites have high thermal conductivity as compared to A359 alloy and even to A359/SiC or A359/(SiC+Si3N4) composites. Microstructures of the composites have shown homogeneous and even distribution of reinforcements within the matrix. Interfacial reactions between particles and matrix were investigated using X-ray diffraction and energy dispersive X-ray analysis. The presence of particles led not only to increase peak hardness of the composites but also to accelerate the aging kinetics. As compared with A359 matrix alloy, compression test of the composites has exhibited a significant increase in the yield and the ultimate compressive strengths with a relative reduction in the failure strain. Those light weight composites have a high potential to be used for automotive and aerospace applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal-matrix%20composite" title="metal-matrix composite">metal-matrix composite</a>, <a href="https://publications.waset.org/abstracts/search?q=squeeze" title=" squeeze"> squeeze</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20properties" title=" compressive properties"> compressive properties</a> </p> <a href="https://publications.waset.org/abstracts/66981/a-comparative-study-of-microstructure-thermal-and-mechanical-properties-of-a359-composites-reinforced-with-sic-si3n4-and-aln-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66981.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">381</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">19</span> Alternative Coating Compositions by Thermal Arc Spraying to Improve the Contact Heat Treatment in Press Hardening</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Philipp%20Burger">Philipp Burger</a>, <a href="https://publications.waset.org/abstracts/search?q=Jonas%20Sommer"> Jonas Sommer</a>, <a href="https://publications.waset.org/abstracts/search?q=Haneen%20Daoud"> Haneen Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Hilmer"> Franz Hilmer</a>, <a href="https://publications.waset.org/abstracts/search?q=Uwe%20Glatzel"> Uwe Glatzel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Press-hardened structural components made of coated high-strength steel are an essential part of the automotive industry when it comes to weight reduction, safety, and durability. Alternative heat treatment processes, such as contact heating, have been developed to improve the efficiency of this process. However, contact heating of the steel sheets often results in cracking within the Al-Si-coated layer. Therefore, this paper will address the development of alternative coating compositions based on Al-Si-X, suitable for contact heating. For this purpose, robot-assisted thermal arc spray was applied to coat the high-strength steel sheets. This ensured high reproducibility as well as effectiveness. The influence of the coating parameters and the variation of the nozzle geometry on the microstructure of the developed coatings will be discussed. Finally, the surface and mechanical properties after contact heating and press hardening will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=press%20hardening" title="press hardening">press hardening</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20stamping" title=" hot stamping"> hot stamping</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20spraying" title=" thermal spraying"> thermal spraying</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20spraying" title=" arc spraying"> arc spraying</a>, <a href="https://publications.waset.org/abstracts/search?q=coating%20compositions" title=" coating compositions"> coating compositions</a> </p> <a href="https://publications.waset.org/abstracts/159998/alternative-coating-compositions-by-thermal-arc-spraying-to-improve-the-contact-heat-treatment-in-press-hardening" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159998.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">94</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Gender Inequalities in Depression among Palestinian Citizens in Israel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nihaya%20Daoud">Nihaya Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Adi%20Finkelstein"> Adi Finkelstein</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Depression is a major public health concern and it is estimated to be the second leading cause of morbidity in 2020. One of the most consistent findings in mental health in the Western societies is inequalities in depression between men and women. Studies on differences in depression between Arab men and women are scarce. In this paper, we use data of a countrywide study on the Arab minority in Israel to compare the prevalence of depressive symptoms between men and women and examine factors that contribute to this gender inequality in the context of Arab society. The study was conducted in 2005-2006. It included a sample of Palestinian citizens of Israel, aged 30–70. The final sample included 902 respondents (381 women and 521 men) who were interviewed face-to-face using a structured questionnaire in Arabic, before which they each signed an informed consent form. The study was approved by the Institutional Review Board at Hadassah – Hebrew University Medical Center. Results show that women had significantly higher depressive symptoms (DS) than men. In addition, while Arab women had steady rates of depressive symptoms between the ages of 40-54 and a peak at the age group of 55-59, among Arab men there was a peak almost every 10 years (more results will show in the full presentation). We assume that our findings might be attributed to the specific structural changes in the Arab society in Israel in the last decades. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arab%20men" title="Arab men">Arab men</a>, <a href="https://publications.waset.org/abstracts/search?q=Arab%20women" title=" Arab women"> Arab women</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20inequality" title=" gender inequality"> gender inequality</a> </p> <a href="https://publications.waset.org/abstracts/45766/gender-inequalities-in-depression-among-palestinian-citizens-in-israel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45766.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">245</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">17</span> Effect of Different Parameters in the Preparation of Antidiabetic Microparticules by Coacervation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nawel%20Ouennoughi">Nawel Ouennoughi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamel%20Daoud"> Kamel Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During recent years, new pharmaceutical dosage forms were developed in the research laboratories and which consists of encapsulating one or more active molecules in a polymeric envelope. Several techniques of encapsulation allow obtaining the microparticles or the nanoparticles containing one or several polymers. In the industry, microencapsulation is implemented to fill the following objectives: to ensure protection, the compatibility and the stabilization of an active matter in a formulation, to carry out an adapted working, to improve the presentation of a product, to mask a taste or an odor, to modify and control the profile of release of an active matter to obtain, for example, prolonged or started effect. To this end, we focus ourselves on the encapsulation of the antidiabetic. It is an oral hypoglycemic agent belonging to the second generation of sulfonylurea’s commonly employed in the treatment of type II non-insulin-dependent diabetes in order to improve profile them dissolution. Our choice was made on the technique of encapsulation by complex coacervation with two types of polymers (gelatin and the gum Arabic) which is a physicochemical process. Several parameters were studied at the time of the formulation of the microparticles and the nanoparticles: temperature, pH, ratio of polymers etc. The microparticles and the nanoparticles obtained were characterized by microscopy, laser granulometry, FTIR and UV-visible spectrophotometry. The profile of dissolution obtained for the microparticles showed an improvement of the kinetics of dissolution compared to that obtained for the active ingredient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coacervation" title="coacervation">coacervation</a>, <a href="https://publications.waset.org/abstracts/search?q=gum%20Arabic" title=" gum Arabic"> gum Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=microencapsulation" title=" microencapsulation"> microencapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a> </p> <a href="https://publications.waset.org/abstracts/39396/effect-of-different-parameters-in-the-preparation-of-antidiabetic-microparticules-by-coacervation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39396.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">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Metallic Coating for Carbon Fiber Reinforced Polymer Matrix Composite Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amine%20Rezzoug">Amine Rezzoug</a>, <a href="https://publications.waset.org/abstracts/search?q=Said%20Abdi"> Said Abdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadjet%20Bouhelal"> Nadjet Bouhelal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Daoud"> Ismail Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the application of metallic coatings on high fiber volume fraction carbon/epoxy polymer matrix composites. For the grip of the metallic layer, a method of modifying the surface of the composite by introducing a mixture of copper and steel powder (filler powders) which can reduce the impact of thermal spray particles. The powder was introduced to the surface at the time of the forming. Arc spray was used to project the zinc coating layer. The substrate was grit blasted to avoid poor adherence. The porosity, microstructure, and morphology of layers are characterized by optical microscopy, SEM and image analysis. The samples were studied also in terms of hardness and erosion resistance. This investigation did not reveal any visible evidence damage to the substrates. The hardness of zinc layer was about 25.94 MPa and the porosity was around (&sim;6.70%). The erosion test showed that the zinc coating improves the resistance to erosion. Based on the results obtained, we can conclude that thermal spraying allows the production of protective coating on PMC. Zinc coating has been identified as a compatible material with the substrate. The filler powders layer protects the substrate from the impact of hot particles and allows avoiding the rupture of brittle carbon fibers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arc%20spray" title="arc spray">arc spray</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion" title=" erosion"> erosion</a> </p> <a href="https://publications.waset.org/abstracts/35535/metallic-coating-for-carbon-fiber-reinforced-polymer-matrix-composite-substrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35535.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">451</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Behavior of Droplets in Microfluidic System with T-Junction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Guellati">A.

The mechanism of micro droplet formation using two immiscible liquids running through a T-junction has been widely studied. We believe that the flow of these two immiscible phases can be of greater important factor that could have an impact on out-flow hydrodynamic behavior, the droplets generated and the size of the droplets. In this study, the type of the capillary tubes used also represents another important factor that can have an impact on the generation of micro droplets. The tygon capillary tubing with hydrophilic inner surface doesn't allow regular out-flows due to the fact that the continuous phase doesn't adhere to the wall of the capillary inner surface. Teflon capillary tubing, presents better wettability than tygon tubing, and allows to obtain steady and regular regimes of out-flow, and the micro droplets are homogeneoussize. The size of the droplets is directly dependent on the flows of the continuous and dispersed phases. Thus, as increasing the flow of the continuous phase, to flow of the dispersed phase stationary, the size of the drops decreases. Inversely, while increasing the flow of the dispersed phase, to flow of the continuous phase stationary, the size of the droplet increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microfluidic%20system" title="microfluidic system">microfluidic system</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20droplets%20generation" title=" micro droplets generation"> micro droplets generation</a>, <a href="https://publications.waset.org/abstracts/search?q=t-junction" title=" t-junction"> t-junction</a>, <a href="https://publications.waset.org/abstracts/search?q=fluids%20engineering" title=" fluids engineering"> fluids engineering</a> </p> <a href="https://publications.waset.org/abstracts/7208/behavior-of-droplets-in-microfluidic-system-with-t-junction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7208.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">342</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> Production of Metal Powder Using Twin Arc Spraying Process for Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Chen">D.

To enhance the properties of the produced tooling using additive manufacturing, prototypes should be produced in short periods. Thereby, this requires a small amount of tailored powders, which either has a high production cost or is commercially unavailable. Hence, in this study, an arc spray atomization approach to produce a tailored metal powder at a lower cost and even in small quantities, in comparison to the conventional powder production methods, was proposed. This approach involves converting commercially available metal wire into powder by modifying the wire arc spraying process. The influences of spray medium and gas pressure on the powder properties were investigated. As a result, particles with smooth surface and lower porosity were obtained, when nonoxidizing gases are used for thermal spraying. The particle size decreased with increasing of the gas pressure, and the particles sizes are in the range from 10 to 70 µm, which is desirable for selective laser melting (SLM). A comparison of microstructure and mechanical behavior of SLM generated parts using arc sprayed powders (alloy: X5CrNiCuNb 16-4) and commercial powder (alloy: X5CrNiCuNb 16-4) was also conducted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20spraying" title=" arc spraying"> arc spraying</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20production" title=" powder production"> powder production</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title=" selective laser melting"> selective laser melting</a> </p> <a href="https://publications.waset.org/abstracts/104457/production-of-metal-powder-using-twin-arc-spraying-process-for-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104457.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">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> The MTHFR C677T Polymorphism Screening: A Challenge in Recurrent Pregnancy Loss</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rim%20Frikha">Rim Frikha</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouha%20Bouayed"> Nouha Bouayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Afifa%20Sellami"> Afifa Sellami</a>, <a href="https://publications.waset.org/abstracts/search?q=Nozha%20Chakroun"> Nozha Chakroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Salima%20Daoud"> Salima Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Keskes"> Leila Keskes</a>, <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Rebai"> Tarek Rebai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Recurrent pregnancy loss (RPL) defined as two or more pregnancy losses, is a serious clinical problem. Methylene-tetrahydro-folate-reductase (MTHFR) polymorphisms, commonly the variant C677T is recognized as an inherited thrombophilia which might affect embryonic development and pregnancy success and cause pregnancy complications as RPL. Material and Methods DNA was extracted from peripheral blood samples and PCR-RFLP was performed for the molecular diagnosis of the C677T MTHFR polymorphism among 70 patients (35 couples) with more than 2 fetal losses. Aims and Objective: The aim of this study is to determine the frequency of MTHFR C677T among Tunisian couples with RPL and to critically analyze the available literature on the importance of MTHFR polymorphism testing in the management of RPL. Result and comments: No C677T mutation was detected in the carriers of RPL. This result would be related to sample size and to different criteria (number of abortion), - The association between MTHFR polymorphisms and pregnancy complications has been reported but with controversial results. - A lack of evidence for MTHFR polymorphism testing previously recommended by ACMG (American College of Medical medicine). Our study highlights the importance of screening of MTHFR polymorphism since the real impact of such thrombotic molecular defect on the pregnancy outcome is evident. - Folic supplementation of these patients during pregnancy can prevent such complications and lead to a successful pregnancy outcome. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=methylenetetrahydrofolate%20reductase" title="methylenetetrahydrofolate reductase">methylenetetrahydrofolate reductase</a>, <a href="https://publications.waset.org/abstracts/search?q=C677T" title=" C677T"> C677T</a>, <a href="https://publications.waset.org/abstracts/search?q=recurrent%20pregnancy%20loss" title=" recurrent pregnancy loss"> recurrent pregnancy loss</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20testing" title=" genetic testing"> genetic testing</a> </p> <a href="https://publications.waset.org/abstracts/44932/the-mthfr-c677t-polymorphism-screening-a-challenge-in-recurrent-pregnancy-loss" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44932.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">307</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> A Multigranular Linguistic ARAS Model in Group Decision Making</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wiem%20Daoud%20Ben%20Amor">Wiem Daoud Ben Amor</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Mart%C3%ADnez%20L%C3%B3pez"> Luis Martínez López</a>, <a href="https://publications.waset.org/abstracts/search?q=Hela%20Moalla%20Frikha"> Hela Moalla Frikha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most of the multi-criteria group decision making (MCGDM) problems dealing with qualitative criteria require consideration of the large background of expert information. It is common that experts have different degrees of knowledge for giving their alternative assessments according to criteria. So, it seems logical that they use different evaluation scales to express their judgment, i.e., multi granular linguistic scales. In this context, we propose the extension of the classical additive ratio assessment (ARAS) method to the case of a hierarchical linguistics term for managing multi granular linguistic scales in uncertain contexts where uncertainty is modeled by means in linguistic information. The proposed approach is called the extended hierarchical linguistics-ARAS method (ARAS-ELH). Within the ARAS-ELH approach, the DM can diagnose the results (the ranking of the alternatives) in a decomposed style, i.e., not only at one level of the hierarchy but also at the intermediate ones. Also, the developed approach allows a feedback transformation i.e the collective final results of all experts able to be transformed at any level of the extended linguistic hierarchy that each expert has previously used. Therefore, the ARAS-ELH technique makes it easier for decision-makers to understand the results. Finally, An MCGDM case study is given to illustrate the proposed approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20ratio%20assessment" title="additive ratio assessment">additive ratio assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20hierarchical%20linguistic" title=" extended hierarchical linguistic"> extended hierarchical linguistic</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-criteria%20group%20decision%20making%20problems" title=" multi-criteria group decision making problems"> multi-criteria group decision making problems</a>, <a href="https://publications.waset.org/abstracts/search?q=multi%20granular%20linguistic%20contexts" title=" multi granular linguistic contexts"> multi granular linguistic contexts</a> </p> <a href="https://publications.waset.org/abstracts/141933/a-multigranular-linguistic-aras-model-in-group-decision-making" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141933.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">206</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">11</span> Synthesis and Characterization of Carboxymethyl Cellulose-Chitosan Based Composite Hydrogels for Biomedical and Non-Biomedical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Uyanga">K.

Limitations on extending their applications have resulted from the synthesis of hydrogels using toxic materials and complex irreproducible processing techniques. In order to promote environmental sustainability, hydrogel efficiency, and wider application, this study focused on the synthesis of composite hydrogels matrices from an edible non-toxic crosslinker-citric acid (CA) using a simple low energy processing method based on carboxymethyl cellulose (CMC) and chitosan (CSN) natural polymers. Composite hydrogels were developed by chemical crosslinking. The results demonstrated that CMC:2CSN:CA exhibited good performance properties and super-absorbency 21× its original weight. This makes it promising for biomedical applications such as chronic wound healing and regeneration, next generation skin substitute, in situ bone regeneration and cell delivery. On the other hand, CMC:CSN:CA exhibited durable well-structured internal network with minimum swelling degrees, water absorbency, excellent gel fraction, and infra-red reflectance. These properties make it a suitable composite hydrogel matrix for warming effect and controlled and efficient release of loaded materials. CMC:2CSN:CA and CMC:CSN:CA composite hydrogels developed also exhibited excellent chemical, morphological, and thermal properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citric%20acid" title="citric acid">citric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fumaric%20acid" title=" fumaric acid"> fumaric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=tartaric%20acid" title=" tartaric acid"> tartaric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20nitrate%20hexahydrate" title=" zinc nitrate hexahydrate"> zinc nitrate hexahydrate</a> </p> <a href="https://publications.waset.org/abstracts/110048/synthesis-and-characterization-of-carboxymethyl-cellulose-chitosan-based-composite-hydrogels-for-biomedical-and-non-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110048.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">152</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">10</span> Effects of the Food Colour Erythrosine on Thyroid Gland Function in Experimental Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maha%20M.Saber">Maha M.Saber</a>, <a href="https://publications.waset.org/abstracts/search?q=Eitedal%20Daoud"> Eitedal Daoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Moetazza%20M.%20Alshafei"> Moetazza M.

The possible adverse effect of erythrosine ER on the thyroid gland function is investigated in albino rats. Forty-five adult male albino rats were divided to three groups two groups will receive ER orally in doses 68 and I36mg/kg respectively. Third group will receive distilled water for three months Sections of thyroid glands were examined for histopathological, morphometric analysis and MIB-I Ki67 (proliferative marker). Serum concentration of triiodothyronine (T3), Thyroxin (T4) and thyrotrophin (TSH) were determined, results showed histological changes in the two treatment groups versus control group in the group with 68mg/kg dose show vaculation of the cytoplasm of follicular cells and pleomorphism of their nuclei. While the other treated group {136mg /kg} showed congestion of blood vessels, hyperplasia of the interstitial cells and increased multilayer of the follicular cells. Highly significant increase in the mean area of the thyroid follicles in both treated groups compared to control group.Erythrosine treated groups showed a very highly significant decrease (P < 0.001) in serum concentration of T3 and T 4 while TSH showed a very highly significant increase versus control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erythrosine" title="erythrosine">erythrosine</a>, <a href="https://publications.waset.org/abstracts/search?q=thyroid" title=" thyroid"> thyroid</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometrics" title=" morphometrics"> morphometrics</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferative%20marker" title=" proliferative marker"> proliferative marker</a> </p> <a href="https://publications.waset.org/abstracts/29603/effects-of-the-food-colour-erythrosine-on-thyroid-gland-function-in-experimental-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29603.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">407</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">9</span> Debating the Role of Patriarchy in the Incidence of Gender-Based Violence in Jordan: Systematic Review of the Literature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nour%20Daoud">Nour Daoud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Patriarchy continues to thrive in Jordan where male-controlled values are still entrenched in a society that is suffering from upsetting percentages of Gender-based Violence (GBV). This paper is a systematic review of the literature with an attempt to evaluate and interpret all available research evidence relevant to determining the extent to which patriarchy contributes to the occurrence, re-occurrence, and continuation of GBV in Jordan. Twenty-one (21) full-text articles were selected for the in-depth review due to meeting the established criteria for inclusion. 81 percent of articles included primary data while 19 percent included secondary data. Analysis of data was based on a specific extraction form that was developed using the ‘Excel’ to respond to the main goal of the paper. Interpretation of data was in light of the theorization of different feminism schools on the relationship between patriarchy and gender-based violence. Findings show that 33 percent of the selected articles affirm that the patriarchal standpoint best explains the role of patriarchy in the incidence of gender-based violence in Jordan under its three main themes (Honor-based Violence, Intimate Partner Violence and Street Harassment). Apart from the limited number of articles that were found debating this argument and the low percentage of articles that acknowledged the role of patriarchy in the incidence of gender-based violence in Jordan, this paper breaks the ice to implement future empirical studies on this subject. Also, it is an invitation for all Jordanian women to unite their efforts in order to eradicate all forms of victimization against them. <p class="card-text"><strong>Keywords:</strong> <a
