On the basis of aptitude to degrade the crude oil and DCPIP assay, two fungal isolates were selected amongst 15 oil degrading strains. Analysis of ITS-1, ITS-2 and amplicon pyrosequencing studies of fungal diversity revealed that these strains belong to Penicillium and Aspergillus species. Two strains that proved to be the most efficient in degrading crude oil was Aspergillus niger (54 %) and Penicillium commune (48 %) Subsequent to two weeks of cultivation in BHS medium the degradation rate were recorded by using spectrophotometer and GC-MS. Hence, it is cleared that these fungal strains has the capability of degradation and can be utilized for cleaning the Saudi Arabian environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fungal%20%20strains" title="fungal strains">fungal strains</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20contaminants" title=" hydrocarbon contaminants"> hydrocarbon contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20identification" title=" molecular identification"> molecular identification</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradation" title=" biodegradation"> biodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS" title=" GC-MS"> GC-MS</a> </p> <a href="https://publications.waset.org/abstracts/36036/isolation-and-molecular-identification-of-two-fungal-strains-capable-of-degrading-hydrocarbon-contaminants-on-saudi-arabian-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36036.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">522</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1606</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 aim was to detect the effect of papaverine on the proliferation and viability of neural stem cells. Rat neural progenitor cells were isolated from embryos (E14) brains. The dispersed tissues were allowed to settle, then, The supernatant was centrifuged at 1,000 g for 5 min. The pellet was placed in Hank’s solution cultured as free-floating neurospheres Dulbecco’s modified Eagle medium (DMEM) and Hams F12 (3:1) supplemented with B27 (Invitrogen GmBH, Karlsruhe, Germany), 20 ng/mL epidermal growth factor (EGF; Biosource, Karlsruhe, Germany), 20 ng/mL recombinant human fibroblast growth factor (rhFGF; R&D Systems, Wiesbaden-Nordenstadt, Germany), and penicillin and streptomycin (1:100; Invitrogen) at 37°C with 7.5% CO2 . Differentiation was initiated by growth factor withdrawal and plating onto a poly-d-lysine/ laminin matrix. The neurospheres were fed every 2-3 days by replacing 50% of the culture media with fresh media. The culture suspension was transferred to a dish containing 16 wells. The wells were divided as follows: 4 wells received no papaverine (control), 4 wells 1 u, 4 wells 5 u and 4 wells 10 u of papaverine solution. In the next 2 weeks, photography (0,4,5,11days) and viability test were done. The photographs were analysed. Results : papaverine didn't affect proliferation of neurospheres, while it affected viability compared to control , this was dose related. Conclusion: This indicates the harmful effect of papaverine suggesting it to be a candidate neurotoxin causing Parkinsonism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurospheres" title="neurospheres">neurospheres</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20stem%20cells" title=" neural stem cells"> neural stem cells</a>, <a href="https://publications.waset.org/abstracts/search?q=papaverine" title=" papaverine"> papaverine</a>, <a href="https://publications.waset.org/abstracts/search?q=Parkinsonism" title=" Parkinsonism"> Parkinsonism</a> </p> <a href="https://publications.waset.org/abstracts/14864/effect-of-papaverine-on-neurospheres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14864.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">660</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">1599</span> Improved Skin Detection Using Colour Space and Texture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Medjram%20Sofiane">Medjram Sofiane</a>, <a href="https://publications.waset.org/abstracts/search?q=Babahenini%20Mohamed%20Chaouki"> Babahenini Mohamed Chaouki</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Benali%20Yamina"> Mohamed Benali Yamina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Skin detection is an important task for computer vision systems. A good method for skin detection means a good and successful result of the system. The colour is a good descriptor that allows us to detect skin colour in the images, but because of lightings effects and objects that have a similar colour skin, skin detection becomes difficult.

In the present study, the molecular hybridization tool was adopted to obtain six Schiﬀ bases of isatin and adamantane-1-carbohydrazide (18–23). Then, their anticonvulsant activity was evaluated using a pentylenetetrazole- (PTZ-) induced seizure model using phenobarbitone as a positive control. Our ﬁndings showed that compounds 18–23 provided signiﬁcant protection against PTZ-induced seizure, and maximum activities were associated with compound 23. Moreover, all investigated compounds increased the latency of induced convulsion and reduced the duration of epilepsy, with compound 23 being the best. Interestingly, most of the synthesized molecules showed a reduction in neurological symptoms and severity of the seizure. Molecular docking studies suggest GABA-A receptor as a potential target, and in silico ADME screening revealed that the pharmaceutical properties of compound 23 are within the speciﬁed limit. Thus, compound 23 was identified as a promising candidate that warrants further drug discovery processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isatin%20and%20adamantane" title="isatin and adamantane">isatin and adamantane</a>, <a href="https://publications.waset.org/abstracts/search?q=anticonvulsant%20activity" title=" anticonvulsant activity"> anticonvulsant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=PTZ-induced%20seizure" title=" PTZ-induced seizure"> PTZ-induced seizure</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20docking" title=" molecular docking"> molecular docking</a> </p> <a href="https://publications.waset.org/abstracts/145055/schiff-bases-of-isatin-and-admantane-1-carbohydrazide-synthesis-characterization-and-anticonvulsant-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145055.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">207</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">1593</span> Study of the Phenomenon Nature of Order and Disorder in BaMn(Fe/V)F7 Fluoride Glass by the Hybrid Reverse Monte Carlo Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidi%20Mohamed%20Mesli">Sidi Mohamed Mesli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Habchi"> Mohamed Habchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Kotbi"> Mohamed Kotbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Benallal"> Rafik Benallal</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelali%20Derouiche"> Abdelali Derouiche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fluoride glasses with a nominal composition of BaMnMF7 (M = FeV assuming isomorphous replacement) have been structurally modelled through the simultaneous simulation of their neutron diffraction patterns by a reverse Monte Carlo (RMC) model and by a Rietveld for disordered materials (RDM) method.

The most common extrapulmonary cause of ALI is sepsis, accounting more than 30% of the cases in humans. Lipopolysaccharide (LPS) has gained wide acceptance as a clinically relevant model of ALI. Lipopolysaccharide is a glycoprotein forming the major constituent of bacterial endotoxin. Losartan is angiotensin II type 1 (AT1) receptor antagonists. It is widely used for management of hypertension. It was recently suggested that losartan protects against septic ALI. It would thereby prevent LPS-induced ALI. Aim of the work and design of the experiment: This work investigated the injurious effect of lipopolysaccharide (LPS) and ALI on adult male albino rat at 24 hours and 14 days of LPS administration and the possible protective role of losartan pretreatment. LPS has deteriorated animal survival and behavior. It increased lung weight and induced lung histological damage. These changes could be much reduced by the losartan pretreatment. Conclusion: Administration of losartan before LPS could largely reduce these LPS/ ALI induced short and long term alterations. It could be recommended that patients susceptible to developing ALI, as in ICU, should receive a protective dose of angitensin II type 1 (AT1) receptor blocker as losartan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acute%20lung%20injury%20%28ALI%29" title="acute lung injury (ALI)">acute lung injury (ALI)</a>, <a href="https://publications.waset.org/abstracts/search?q=lipopolysaccharide%20%28LPS%29" title=" lipopolysaccharide (LPS)"> lipopolysaccharide (LPS)</a>, <a href="https://publications.waset.org/abstracts/search?q=losartan" title=" losartan "> losartan </a> </p> <a href="https://publications.waset.org/abstracts/24421/possible-protective-role-of-angiotensin-ii-antagonist-on-bacterial-endotoxin-induced-acute-lung-injury-morphological-study-on-adult-male-albino-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24421.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">607</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">1589</span> Power Quality Evaluation of Electrical Distribution Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Idris%20S.%20Abozaed">Mohamed Idris S.

This sudden increase in the number of concerns over power quality problems is a result of the huge increase in the use of non-linear loads. In this paper, power quality evaluation of some distribution networks at Misurata - Libya has been done using a power quality and energy analyzer (Fluke 437 Series II). The results of this evaluation are used to minimize the problems of power quality. The analysis shows the main power quality problems that exist and the level of awareness of power quality issues with the aim of generating a start point which can be used as guidelines for researchers and end users in the field of power systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=power%20quality%20disturbances" title="power quality disturbances">power quality disturbances</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality%20evaluation" title=" power quality evaluation"> power quality evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20distribution%20networks" title=" electrical distribution networks "> electrical distribution networks </a> </p> <a href="https://publications.waset.org/abstracts/11250/power-quality-evaluation-of-electrical-distribution-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11250.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">1588</span> Dynamic Modeling of Orthotropic Cracked Materials by X-FEM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Houcine%20Habib">S.

In this approach, the finite element method model is first created and then enriched by special orthotropic crack tip enrichments and Heaviside functions in the framework of partition of unity. The mixed mode stress intensity factor (SIF) is computed using the interaction integral technique based on J-integral in order to predict cracking behavior of the structure. The developments of these procedures are programmed and introduced in a self-software platform code. To assess the accuracy of the developed code, results obtained by the proposed method are compared with those of literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=X-FEM" title="X-FEM">X-FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20intensity%20factor" title=" stress intensity factor"> stress intensity factor</a>, <a href="https://publications.waset.org/abstracts/search?q=crack" title=" crack"> crack</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20orthotropic%20behavior" title=" dynamic orthotropic behavior"> dynamic orthotropic behavior</a> </p> <a href="https://publications.waset.org/abstracts/38362/dynamic-modeling-of-orthotropic-cracked-materials-by-x-fem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38362.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">569</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">1587</span> Basin Geometry and Salt Structures in the Knana/Ragoubet Mahjbia Ranges, North of Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Montassar%20Ben%20Slama">Mohamed Montassar Ben Slama</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Fadel%20Ladeb"> Mohamed Fadel Ladeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ghanmi"> Mohamed Ghanmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Ben%20Youssef"> Mohamed Ben Youssef</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouad%20Zargouni"> Fouad Zargouni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The salt province Basin in Northern Tunisia is a complex of late Triassic to Early Cretaceous rift and sag basins which was inverted during the Tertiary folding. The deposition of evaporitic sediments during the Late Triassic times played a major role in the subsequent tectonic evolution of the basin. Within southern tethyan passive marge, the ductile salt mass shown early mobilization, vertical transport and withdrawal of the evaporites. These movements influenced the sedimentation during the late Jurassic and Early Cretaceous. The evaporites also influenced deformation during the inversion of the basin and the development of the Tertiary and Quaternary folding. In the studied area, the biostratigraphic and tectonic map analysis of the region of Jebel el Asoued / Ragoubet el Mahjbia can resolve between the hypotheses of the diapiric intrusion of the Triassic salt and the lateral spreading of the Triassic salt as salt ‘glacier’. Also the variation in thickness and facies of the Aptian sediments demonstrates the existence of continental rise architecture at the Aptian time. The observation in a mappable outcrop of the extension segment of the graben fault of Bou Arada on the one hand confirms the existence of a Cretaceous extensive architecture and the tectonic inversion during the Tertiary time has not filled the main game distension. The extent of our observations of Triassic/Aptian and Triassic/Early Campanian contacts, we propose a composite salt ‘glacier’ model as the structures recorded in the Gulf of Mexico in the subsurface and in the Ouenza east Algeria and in Tunisia within Fedj el Adoum, Touiref-Nebeur and Jebel Ech Cheid in the outcrops. <p class="card-text"><strong>Keywords:</strong> <a
