Therefore we will obtain the current-voltage characteristics (I-V) of the reverse-biased structure which may include the effect of breakdown.The geometrical model assumes that the polysilicon layer is composed by a succession of defined mean grain size crystallites, separated by lateral grain boundaries which are parallel to the metallurgic junction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breakdown" title="breakdown">breakdown</a>, <a href="https://publications.waset.org/abstracts/search?q=polycrystalline%20silicon" title=" polycrystalline silicon"> polycrystalline silicon</a>, <a href="https://publications.waset.org/abstracts/search?q=PIN" title=" PIN"> PIN</a>, <a href="https://publications.waset.org/abstracts/search?q=grain" title=" grain"> grain</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20ionization" title=" impact ionization"> impact ionization</a> </p> <a href="https://publications.waset.org/abstracts/1337/simulation-of-i-v-characteristics-of-lateral-pin-diode-on-polysilicon-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1337.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">380</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">81</span> Experimental Evaluation of Workability and Compressive Strength of Concrete With Sediments From Dam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khouadjia%20Mohamed%20Lyes%20Kamel">Khouadjia Mohamed Lyes Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Bensalem%20Sara"> Bensalem Sara</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdou%20Kamel"> Abdou Kamel</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkadi%20Ahmed%20Abderraouf"> Belkadi Ahmed Abderraouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Kessal%20Oussama"> Kessal Oussama</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The experimental study was conducted on sediments dredging from the dam of Bni Haroun, the most important and the largest dam in Algeria.

According to this participatory point of view, the effectiveness of place branding strategies cannot be achieved without citizen involvement. However, the role of all residents as key participants in the city branding process has not been widely discussed. The aim of this paper was to determine how citizens’ involvement impacts their perceptions of the city's image, using a multivariate model. To test our hypotheses hypothetical-deductive reasoning by the quantitative method was chosen. Our investigation is based on data collected through a survey among 200 citizens of Casablanca. Results show that the more citizens are involved, the more they tend to evaluate the image of the brand positively. Additionally, the degree of involvement seems to impact satisfaction and a sense of belonging. As well, the more citizen develops a sense of belonging to the city, the more favorable his or her perception of the brand image is. Ultimately, the role of citizens shouldn’t be limited to reception. They are also Co-creators of the brand, who ensure the correlation of the brand with authentic place roots. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citybranding" title="citybranding">citybranding</a>, <a href="https://publications.waset.org/abstracts/search?q=sense%20of%20belonging" title=" sense of belonging"> sense of belonging</a>, <a href="https://publications.waset.org/abstracts/search?q=satisfaction" title=" satisfaction"> satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=impact" title=" impact"> impact</a>, <a href="https://publications.waset.org/abstracts/search?q=brand%E2%80%99s%20image" title=" brand’s image"> brand’s image</a> </p> <a href="https://publications.waset.org/abstracts/143521/the-impact-of-citizens-involvement-on-their-perception-of-the-brands-image-the-case-of-the-city-of-casablanca" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143521.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">176</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">78</span> Characteristics of Handgrip (Kumi-Kata) Profile of Georgian Elite Judo Athletes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Belkadi%20Adel">Belkadi Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Beboucha%20Wahib"> Beboucha Wahib</a>, <a href="https://publications.waset.org/abstracts/search?q=Cherara%20lalia"> Cherara lalia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: The aim of this study was to investigate the characteristics of Kumi-kata in elite judokas and characterize the kinematic and temporal parameters of different types of handgrip (HG). Method: fourteen participated in this study male athlete (23.5±2.61 years; 1.81±0.37 0 m; 87.25±22.75 kg), members of the Georgian Judo team. To characterize the dominance and types of kumi-kata used, videos of international competitions from each athlete were analyzed, and to characterize kinematic and temporal parameters and handgrip, and the volunteers pressed a digital dynamometer with each hand for 30 seconds(s) after a visual signal. Results: The values of 0.26±0.69s and 0.31±0.03s for reaction time were obtained, respectively, in the full grip and pinch grip; 19.62±18.83N/cm/s and 6.17±3.48N/cm/s for the rate of force development; 475,21 ± 101,322N and 494,65±112,73 for the FDR; 1,37 ± 0,521s and 1,45 ± 0,824s for the time between the force onset to the TFP; and 41,27±4,54N/cm/s and 45,16 ± 5,64N/cm/s for the fall index, in the dominant hand. There was no significant difference between hands for any variable, except for the dominance of Kumi-kata (p<0.05) used in combat. Conclusion: The dominance of application of the Kumi-kata is a technical option, as it does not depend on the kinetic-temporal parameters of the handgrip. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand%20grip" title="hand grip">hand grip</a>, <a href="https://publications.waset.org/abstracts/search?q=judo" title=" judo"> judo</a>, <a href="https://publications.waset.org/abstracts/search?q=athletes" title=" athletes"> athletes</a>, <a href="https://publications.waset.org/abstracts/search?q=Kumi-Kata" title=" Kumi-Kata"> Kumi-Kata</a> </p> <a href="https://publications.waset.org/abstracts/142125/characteristics-of-handgrip-kumi-kata-profile-of-georgian-elite-judo-athletes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142125.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">189</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">77</span> Sporting Events among the Disabled between Excellence and Ideal in Motor Performance: Analytical Descriptive Study in Some Paralympic Sports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guebli%20Abdelkader">Guebli Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Reguieg%20Madani"> Reguieg Madani</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkadi%20Adel"> Belkadi Adel</a>, <a href="https://publications.waset.org/abstracts/search?q=Sbaa%20Bouabdellah"> Sbaa Bouabdellah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The identification of mechanical variables in the motor performance trajectory has a prominent role in improving skill performance, error-exceeding, it contributes seriously to solving some problems of learning and training. The study aims to highlight the indicators of motor performance for Paralympic athletes during the practicing sports between modelling and between excellence in motor performance, this by taking into account the distinction of athlete practicing with special behavioral skills for the Paralympic athletes. In the study, we relied on the analysis of some previous research of biomechanical performance indicators during some of the events sports (shooting activities in the Paralympic athletics, shooting skill in the wheelchair basketball). The results of the study highlight the distinction of disabled practitioners of sporting events identified in motor performance during practice, by overcoming some physics indicators in human movement, as a lower center of body weight, increase in offset distance, such resistance which requires them to redouble their efforts. However, the results of the study highlighted the strength of the correlation between biomechanical variables of motor performance and the digital level achievement similar to the other practitioners normal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sports" title="sports">sports</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20disabled" title=" the disabled"> the disabled</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20performance" title=" motor performance"> motor performance</a>, <a href="https://publications.waset.org/abstracts/search?q=Paralympic" title=" Paralympic"> Paralympic</a> </p> <a href="https://publications.waset.org/abstracts/92665/sporting-events-among-the-disabled-between-excellence-and-ideal-in-motor-performance-analytical-descriptive-study-in-some-paralympic-sports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92665.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">283</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">76</span> Antibacterial and Antifungal Activities of the Essential Oil of Pulicaria jaubertii Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Methaq%20Algabr">Methaq Algabr</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Al-Hajj"> Nabil Al-Hajj</a>, <a href="https://publications.waset.org/abstracts/search?q=Ameerh%20Jaber"> Ameerh Jaber</a>, <a href="https://publications.waset.org/abstracts/search?q=Amtellah%20Alshotobi"> Amtellah Alshotobi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaima%27a%20Al-suryhi"> Shaima'a Al-suryhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Gadah%20Whaban"> Gadah Whaban</a>, <a href="https://publications.waset.org/abstracts/search?q=Nawal%20Alshehari"> Nawal Alshehari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Steam distillation of the essential oil of P. jaubertii was performed using a Clevenger apparatus.

The emergence of MOOCs caused a great deal of interest amongst academics and technology experts as well as ordinary people. Some of the authors who wrote on MOOCs perceived it as the next big thing that will disrupt education. Other authors saw it as another fad that will go away once it ran its course (as most fads often do). But MOOCs did not turn out to be a fad and it is still around. Most importantly, they evolved into something that is beginning to look like a viable business model. This paper explores this phenomenon within the theoretical frameworks of disruptive innovations and jobs to be done as developed by Clayton Christensen and his colleagues and its implications for the future of higher education (HE). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MOOCs" title="MOOCs">MOOCs</a>, <a href="https://publications.waset.org/abstracts/search?q=disruptive%20innovations" title=" disruptive innovations"> disruptive innovations</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=jobs%20theory" title=" jobs theory"> jobs theory</a> </p> <a href="https://publications.waset.org/abstracts/88600/innovating-and-disrupting-higher-education-the-evolution-of-massive-open-online-courses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88600.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">270</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">71</span> Real-time PCR to Determine Resistance Genes in ESBLEscherichia Coli Strains Stored in the Epidemic Diseases Laboratory of the National Institute of Hygiene (INH)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Qasmaoui">A.

The production of ESBL extended spectrum β-lactamase enzymes is the main mechanism of resistance to β-lactam antibiotics in Escherichia coli. The objective of our work is to determine the resistance genes in E. coli strains.ESBL coli stored at the epidemic diseases laboratory of the National Institute of Hygiene. The strains were identified according to the classic bacteriological criteria. An antibiogram was performed on the strains isolated by the Mueller Hinton agar disc diffusion method. The production of ESBL in the strains was detected by the synergy assay technique and confirmed for the presence of the blaCTX-M1, blaCTX-M2, blaTEM, blaSHV, blaOXA-48 genes by gene amplification . Of the 27 observed strains of E.coli, 17 isolated strains present the phenotype of extended-spectrum Beta-lactamase with a percentage of 63%.. All 18 cefotaxime-resistant strains were analyzed for an ESBL phenotype. All strains were positive in the double-disc synergy assay. The fight against the emergence and spread of these multi-resistant antibiotic-resistant strains requires the reasonable use of antibiotics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E%20coli" title="E coli">E coli</a>, <a href="https://publications.waset.org/abstracts/search?q=BLSE" title=" BLSE"> BLSE</a>, <a href="https://publications.waset.org/abstracts/search?q=CTX" title=" CTX"> CTX</a>, <a href="https://publications.waset.org/abstracts/search?q=TEM" title=" TEM"> TEM</a>, <a href="https://publications.waset.org/abstracts/search?q=SHV" title=" SHV"> SHV</a>, <a href="https://publications.waset.org/abstracts/search?q=OXA" title=" OXA"> OXA</a>, <a href="https://publications.waset.org/abstracts/search?q=r%C3%A9sistance%20aux%20antibiotique" title=" résistance aux antibiotique"> résistance aux antibiotique</a> </p> <a href="https://publications.waset.org/abstracts/193448/real-time-pcr-to-determine-resistance-genes-in-esblescherichia-coli-strains-stored-in-the-epidemic-diseases-laboratory-of-the-national-institute-of-hygiene-inh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193448.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">18</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">70</span> Hate Speech Detection Using Deep Learning and Machine Learning Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Shawkat">Nabil Shawkat</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamil%20Saquer"> Jamil Saquer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social media has accelerated our ability to engage with others and eliminated many communication barriers.

The results of several simulations are reported. The first study was performed for NACA0012 of hydrofoil with different meshes, this section is analyzed at h/c= 1, 0345 for 2D. In the second simulation, a mathematically defined Wigley hull form is used to investigate the application of a commercial CFD code in prediction of the total resistance and its components from tangential and normal forces on the hull wetted surface. The computed resistance and wave profiles are used to estimate the coefficient of the total resistance for Wigley hull advancing in calm water under steady conditions. The commercial CFD software FLUENT version 12 is used for the computations in the present study. The calculated grid is established using the code computer GAMBIT 2.3.26. The shear stress k-ωSST model is used for turbulence modeling and the volume of the fluid technique is employed to simulate the free-surface motion. The second order upwind scheme is used for discretizing the convection terms in the momentum transport equations, the Modified HRICscheme for VOF discretization. The results obtained compare well with the experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=free%20surface%20flows" title="free surface flows">free surface flows</a>, <a href="https://publications.waset.org/abstracts/search?q=breaking%20waves" title=" breaking waves"> breaking waves</a>, <a href="https://publications.waset.org/abstracts/search?q=boundary%20layer" title=" boundary layer"> boundary layer</a>, <a href="https://publications.waset.org/abstracts/search?q=Wigley%20hull" title=" Wigley hull"> Wigley hull</a>, <a href="https://publications.waset.org/abstracts/search?q=volume%20of%20fluid" title=" volume of fluid "> volume of fluid </a> </p> <a href="https://publications.waset.org/abstracts/26743/numerical-simulation-of-free-surface-water-wave-for-the-flow-around-naca-0012-hydrofoil-and-wigley-hull-using-vof-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26743.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">376</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">67</span> Influence of Age on Some Testicular and Spermatic Parameters in Kids and Bucks in Local Breed Arbia in Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boukhalfa%20Djemouai">Boukhalfa Djemouai</a>, <a href="https://publications.waset.org/abstracts/search?q=Belkadi%20Souhila"> Belkadi Souhila</a>, <a href="https://publications.waset.org/abstracts/search?q=Safsaf%20Boubakeur"> Safsaf Boubakeur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To increase the profitability of the national herd so that it can meet the needs of the population, Algeria has proceeded to the introduction of new reproductive biotechnologies, including artificial insemination on natural heat, by induction and heat synchronization. This biotechnology uses the male way for the creation and dissemination of genetic progress. The study has focused on 30 goat kids and bucks local breed aged between 03 and 24 months, divided into 03 groups 03-06 months[Grp 1; n=9], 07-10 months [Grp 2; n=13] and 11-24 months [Grp 3; n=8], in order to determine the influence of age on testicular evolution by measurements of testis and scrotum, and the epididymis sperm parameters evaluation. These parameters are influenced by age variations (sperm and spermocytogram). The examined parameters have focused on testicular weight (grams), the scrotal circumference (cm), mass mobility (%), vitality rate (%), sperm concentration (x 109), and percentage of abnormal spermatozoa (%). The ANOVA reveals a significance effect of age on parameters: testis weight, scrotal circumference, sperm concentration, motility varying between high (p < 0.01) to very high significance (p < 0.001), while in viability and abnormalities no significance was observed between all groups. The value of these parameters increased significantly until the age of 02 years, while that of sperm abnormalities has increased in Grp2. The histological study of testicular development shows that the genetic spermatozoa function characterized by cell proliferation, which is more and more intense starting from the age of 05 months and can be considered as an age of puberty in the local breed goat Arbia and increases with animal age. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kids%20and%20bucks" title="kids and bucks">kids and bucks</a>, <a href="https://publications.waset.org/abstracts/search?q=epididymis%20sperm" title=" epididymis sperm"> epididymis sperm</a>, <a href="https://publications.waset.org/abstracts/search?q=testicular%20measurements" title=" testicular measurements"> testicular measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=Arbia%20breed" title=" Arbia breed"> Arbia breed</a> </p> <a href="https://publications.waset.org/abstracts/125017/influence-of-age-on-some-testicular-and-spermatic-parameters-in-kids-and-bucks-in-local-breed-arbia-in-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125017.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">132</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">66</span> Biogas Production Improve From Waste Activated Sludge Using Fenton Oxidation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Hassiba%20Zemmouri">A.

The most significant one was, yet, to happen during the colonial era, where the Arab Muslim ‘cosmic’ clock was recalibrated to match a more or less modern perception of time. As for modern civic and political experiences of life, they were left in a state of inertia. This article considers the problematic amalgam of traditional Islam, modernity and democratization in the Arab world, as well as the effects on the configuration of recent progressive endeavours. It is argued that the assimilation of democratic ethos - as a requisite for modernity - depends on the assimilation of power, progress and time, by what is referred to as the Umma. Drawing on postmodern and political literature, it is suggested that because of a conceptualization which draws mainly on traditional Islam, the Umma and the state in the Arab world remain in conflict while, at times, they appear to act collaboratively, either to embrace modernity or to obstruct democratization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islam" title="Islam">Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=democracy" title=" democracy"> democracy</a>, <a href="https://publications.waset.org/abstracts/search?q=Arab%20world" title=" Arab world"> Arab world</a>, <a href="https://publications.waset.org/abstracts/search?q=modernity" title=" modernity"> modernity</a> </p> <a href="https://publications.waset.org/abstracts/185127/conceptualizing-power-progress-and-time-an-essay-on-islam-and-democracy-in-the-arab-world" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185127.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">43</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">61</span> Hydro-Mechanical Behavior of Calcareous Soils in Arid Region </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Goual">I.

The monitoring of bacterial growth by measuring the optical density at 600 nm by spectrophotometer and the surface tension clearly showed the ability of Pseudomonas luteola to produce biosurfactants at various conditions of the culture medium. The biosurfactant produced in the pharmaceutical reject medium generated a decrease in the surface tension with a percentage of 19.4% greater than the percentage obtained when using whey which is 7.0%. The pharmaceutical rejection is diluted at various percentages ranging from 5% to 100% in order to study the effect of the concentration on the biosurfactant production.

Farmers tend to improve the local native herds by crossbreeding with Damascus bucks. The aim of the current investigation was to study the effects of physiological status on blood progesterone and some biochemical parameters in Shami goats and their crosses with local breed in arid conditions of Algeria. Ten does with an age range of 1.5- 3 years and BSC between 2.5 and 3.5 were used. Female goats were divided into two groups of five animals each: Damascus, and crossbred (Damascus x Arbia). All females were estrus synchronized and naturally mated. Blood samples were collected before intravaginal sponge insertion (non- pregnant), in early (30 days after sponge removal), mid (90 days), late pregnancy (130 days) and after kidding (30 days post-partum). Results demonstrate a significant effect of the reproductive stage on progesterone (P4) levels in both groups, on glycemia and cholesterolemia in crossbred does (p<0.05) and on albuminemia and uremia in Damascus ones. Concentrations of triglycerides, total proteins, globulin and creatinine revealed no significant difference between physiological phases in both groups (p>0.05). Breed effect was detected in early and mid-pregnancy for P4, in early pregnancy and lactation for total proteins and in lactation for globulin with lower concentrations in Damascus compared to crossbred does. Changes in P4 and biochemical profiles of both groups reflect the female goat’s adaptation to increased requirement of gestation and lactation in arid conditions of Algeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=damascus%20goat" title="damascus goat">damascus goat</a>, <a href="https://publications.waset.org/abstracts/search?q=crossbred" title=" crossbred"> crossbred</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive%20status" title=" reproductive status"> reproductive status</a>, <a href="https://publications.waset.org/abstracts/search?q=progesterone" title=" progesterone"> progesterone</a>, <a href="https://publications.waset.org/abstracts/search?q=biochemical%20metabolites" title=" biochemical metabolites"> biochemical metabolites</a> </p> <a href="https://publications.waset.org/abstracts/183990/impact-of-breed-and-physiological-status-on-blood-content-of-goats-in-arid-conditions-of-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183990.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">61</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">57</span> Hydro-Mechanical Behavior of a Tuff and Calcareous Sand Mixture for Use in Pavement in Arid Region</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Goual">I.

To start with, the equations of the ideal magnetohydrodynamics theory will be presented describing the basic behaviour of magnetically confined plasma and equations are discretized with finite element method in cylindrical coordinates. The discharge chamber is assumed to be axially symmetric and the plasma is treated as a compressible gas. Plasma generation due to ionization is added to the continuity equation. Magnetic vector potential equation is solved for the electromagnetic fields. A strong dependence of the plasma properties on the discharge conditions and the gas temperature is obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct-coupled%20model" title="direct-coupled model">direct-coupled model</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic" title=" magnetohydrodynamic"> magnetohydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20torch%20simulation" title=" plasma torch simulation"> plasma torch simulation</a> </p> <a href="https://publications.waset.org/abstracts/38779/2d-rf-icp-torch-modelling-with-fluid-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38779.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">433</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">55</span> Efficient Ground Targets Detection Using Compressive Sensing in Ground-Based Synthetic-Aperture Radar (SAR) Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gherbi%20Nabil">Gherbi Nabil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Detection of ground targets in SAR radar images is an important area for radar information processing. In the literature, various algorithms have been discussed in this context. However, most of them are of low robustness and accuracy. To this end, we discuss target detection in SAR images based on compressive sensing. Firstly, traditional SAR image target detection algorithms are discussed, and their limitations are highlighted. Secondly, a compressive sensing method is proposed based on the sparsity of SAR images. Next, the detection problem is solved using Multiple Measurements Vector configuration. Furthermore, a robust Alternating Direction Method of Multipliers (ADMM) is developed to solve the optimization problem. Finally, the detection results obtained using raw complex data are presented. Experimental results on real SAR images have verified the effectiveness of the proposed algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compressive%20sensing" title="compressive sensing">compressive sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=raw%20complex%20data" title=" raw complex data"> raw complex data</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20aperture%20radar" title=" synthetic aperture radar"> synthetic aperture radar</a>, <a href="https://publications.waset.org/abstracts/search?q=ADMM" title=" ADMM"> ADMM</a> </p> <a href="https://publications.waset.org/abstracts/191958/efficient-ground-targets-detection-using-compressive-sensing-in-ground-based-synthetic-aperture-radar-sar-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191958.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">18</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">54</span> Correlation between Seismic Risk Insurance Indexes and Uninhabitability Indexes of Buildings in Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Mekaoui">Nabil Mekaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacer%20Jabour"> Nacer Jabour</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhamid%20Allaoui"> Abdelhamid Allaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Abderahim%20Oulidi"> Abderahim Oulidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The reliability of several insurance indexes of the seismic risk is evaluated and compared for an efficient seismic risk coverage of buildings in Morocco, thus, reducing the basic risk. A large database of earthquake ground motions is established from recent seismic events in Morocco and synthetic ground motions compatible with the design spectrum in order to conduct nonlinear time history analyses on three building models representative of the building stock in Morocco. The uninhabitability index is evaluated based on the simulated damage index, then correlated with preselected insurance indexes. Interestingly, the commonly used peak ground acceleration index showed poor correlation when compared with other indexes, such as spectral accelerations at low periods. Recommendations on the choice of suitable insurance indexes are formulated for efficient seismic risk coverage in Morocco. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=catastrophe%20modeling" title="catastrophe modeling">catastrophe modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=damage" title=" damage"> damage</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquake" title=" earthquake"> earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=reinsurance" title=" reinsurance"> reinsurance</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20hazard" title=" seismic hazard"> seismic hazard</a>, <a href="https://publications.waset.org/abstracts/search?q=trigger%20index" title=" trigger index"> trigger index</a>, <a href="https://publications.waset.org/abstracts/search?q=vulnerability" title=" vulnerability"> vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/170497/correlation-between-seismic-risk-insurance-indexes-and-uninhabitability-indexes-of-buildings-in-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170497.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">69</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">53</span> Evaluating the Suitability and Performance of Dynamic Modulus Predictive Models for North Dakota’s Asphalt Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duncan%20Oteki">Duncan Oteki</a>, <a href="https://publications.waset.org/abstracts/search?q=Andebut%20Yeneneh"> Andebut Yeneneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Daba%20Gedafa"> Daba Gedafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Suleiman"> Nabil Suleiman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most agencies lack the equipment required to measure the dynamic modulus (|E*|) of asphalt mixtures, necessitating the need to use predictive models. This study compared measured |E*| values for nine North Dakota asphalt mixes using the original Witczak, modified Witczak, and Hirsch models. The influence of temperature on the |E*| models was investigated, and Pavement ME simulations were conducted using measured |E*| and predictions from the most accurate |E*| model. The results revealed that the original Witczak model yielded the lowest Se/Sy and highest R² values, indicating the lowest bias and highest accuracy, while the poorest overall performance was exhibited by the Hirsch model. Using predicted |E*| as inputs in the Pavement ME generated conservative distress predictions compared to using measured |E*|. The original Witczak model was recommended for predicting |E*| for low-reliability pavements in North Dakota. <p class="card-text"><strong>Keywords:</strong> <a
