This study aims to investigate the effect of corpus consultation on learners' writing performance and attitudes at Sultan Qaboos University.The study population consists of 52 students enrolled in the Writing 2 course (LANC 1120) in the Language Center in the spring semester 2012. The sample comprises two intact classes (N=20). One class functioned as the experimental group and the other as the control group. Both groups used the traditional reference tools in editing written drafts in addition to the corpus program in the experimental group.Two instruments were used in the current study: a writing achievement test to measure students' performance in grammar and vocabulary. An attitude questionnaire was also developed by the researcher based on the available literature to elicit students' attitudes towards the use of the corpus in writing.The results of the study showed the following:1. There was no significant difference at the .05 level in the writing performanceof the experimental and the control groups as far as the grammar knowledge isconcerned, 2. The results of the attitude questionnaire analysis revealed that the students inthe experimental group had a highly positive attitude towards the use of the corpus in writingIn the light of these findings, recommendations are made for further research.

Le présent travail porte sur l’étude de formation de siliciures à partir du système Ni/Co/Si(111). Les échantillonssont obtenus par dépôt d’une bicouche métallique de cobalt et de nickel par évaporation sous vide sur un substrat desilicium monocristallin orienté (111). Pour amorcer la réaction de siliciuration en phase solide, ces échantillons ont subidifférents recuits (300, 500, 700, 900°C).Nous avons utilisé trois techniques de caractérisation, à savoir, la diffraction des rayons X sous incidence rasante(GIXRD), la spectroscopie de rétrodiffusion de Rutherford (RBS) et la microscopie électronique à balayage, pour suivrel’évolution de nos échantillons en fonction du recuit subi.Après analyse des résultats obtenus, nous avons remarqué que la formation de siliciure est observable à partir de latempérature de 700°C par la présence de la phase du siliciure de cobalt CoSi et le début de formation de la phase CoSi2Le décalage angulaire des pics de diffraction de la phase CoSi quidevient majoritaire à 900°C. Les images MEB nous a permis de constater l’évolution de l’état de la surface de noséchantillons qui devient plus rugueuse en augmentant la température.2 vers les petits angles annonçant une augmentationdu volume de sa maille et l’interdiffusion des éléments Co, Ni, Si observée par RBS, nous a mené à croire qu’il y aformation de la solution solide (CoSi2-Ni) ou plus probablement la formation d’un siliciure ternaire de type CoxNi1-xSi2.

La surveillance d'état des machines est importante pour vérifier l’efficacité des usines et la sûreté des ouvriers. Une variété de techniques d'analyse des signaux de vibration a été déjà employée dans le diagnostic de défauts des machines électriques. Cette étude traite le diagnostic à distance des systèmes électriques. En se basant sur l’Internet et les nouvelles technologies de communication mobile nous avons développé un système de surveillance à distance. L’utilisation d’un tel système offre plusieurs avantages: réduire les coûts de production, améliorer la fiabilité, réduire le temps d'arrêt des machines et assurer l’efficacité des opérations. Les utilisateurs peuvent consulter l’état de la machine par l’Internet.

Chaetostomella cylindrica and Chaetostomella lurida are cryptic and sympatric non-frugivorous fruit flies that cannot be differentiated morphologically. Ecologically, the two species differ C. cylindrica is highly oligophagous while C. lurida is monophag

Explorar el patrimonio político y cultural de los Moriscos en la Regencia de Argel no esuna cosa fácil. Para eso, es imprescindible ver como se estableció la sociedad morisca en laRegencia de Argel antes de la Reconquista de al Ándalus.Con el general Tarik Ibn Ziyad bajo las órdenes de su superior Musa Ibn Nusair,gobernador del norte de África, se conquista la Península ibérica. Esta conquista da elnacimiento del espacio de al- Ándalus, gobernado por los musulmanes durante ocho siglos,del año de 711 hasta el año 1492, edificando una de las civilizaciones más brillantes en laHistoria de la Humanidad.Muchos historiadores consideraron la España musulmana como un gran centro cultural, elmás resplandeciente de la época y otros calificaron la presencia musulmana en al- Ándaluscomo la Edad de Oro islámica.Antes de la Reconquista de al Ándalus, los musulmanes, judíos y cristianos vivieron enpaz; no conocieron ni guerras ni tampoco expulsión por causa de la creencia. Después de lamuerte de Almanzor, empezó la fitna entre los musulmanes y, los cristianos empezaron laReconquista de sus tierras, a partir del siglo XI. Durante los IV siglos siguientes, al Ándalusfue reconquistada por completo, quedando en el siglo XIII sólo el reino de Granada quepudo resistir al avance de los Reyes Católicos, durante III siglos.

Background: Campylobacter jejuni is the main cause of gastroenteritis worldwide. Symptoms of C. jejuni infections range from asymptomatic to bloody diarrhea. Previous studies showed a strong association between diversity in presence of bacterial virulence factors including: Campylobacter invasion protein B (CiaB), fibronectin-binding outer membrane protein (CadF), cytolethal distending toxin B (CdtB), Clp ATP dependent protease (ClpP) and HtrB protein. The aim of this project was to study the association between prevalence of the aforementioned genes, the antimicrobial resistance patterns of the isolates, and the demographic data of patients. Methodology: A total of 174 archived isolates of C. jejuni were obtained from stool samples of symptomatic patients in the Microbiology Laboratory at Hamad Medical Corporation (HMC). Isolates were revived using selective media and DNA was extracted from posititve colonies. C. jejuni isolates were screened by real-time PCR for the presence of five of virulence-associated genes. Isolates were also tested for the antimicrobial susceptibility to common antimicrobial agents used in HMC including: chloramphenicol, ciprofloxacin, erythromycin and gentamicin. Demographic data such as age, gender and nationality were also collected fromt he medical charts of subjects included in this study. Results: 75% of the isolates were obtained from patients younger than 5 years old. 60.3% of the participants were males and 57% of the subjects were from the Arabian Peninsula. All the virulence genes were detected with different percentages. There was a significant association between gender (male) and presence of two of the virulence genes cadF and clpP (P value: 0.022 for both). No clear associations were found between presence of the remaining virulence genes and demographic data; or between antimicrobial susceptibility patterns with age, gender and nationality. Isolates were highly sensitive to all antimicrobial agents except ciprofloxacin, where high resistance was observed. Conclusion: Gender (male) was strongly associated with presence of cadF and clpP genes. Other correlations between prevalence of virulence genes, antimicrobial susceptibility and demographic data were found to be insignificant. Further investigation on the characteristics Campylobacter jejuni, and how they induce different symptoms and responses to their infection are needed.

Chick lit emerged as a literary genre three decades ago. Chick lit swept the literary world by storm overnight and transformed the world of contemporary women’s fiction. Chick lit’s light tone makes it easy to overlook the idea that chick lit novels still reinforce patriarchal views about women. Therefore, this work sets to prove the presence post-feminist backlash in chick lit novels through the analysis of two chick lit novels. In Lauren Weisberger’s two chick lit novels The Devil Wears Prada (2003) and The Singles Game (2016), post-feminist backlash against women is an underlying presence. In both novels patriarchal views about women and professional work are reestablished. Through the depiction of miserable stressed career women, the novels implies that women are not fit for professional career and a happy, fulfilled women to leads a more domestic lifestyle. Moreover, The Singles Game showcases the renewed focus on female body in the women’s sports and exposes underlying sexism that still prevails in western society. Furthermore, The Devil Wears Prada showcases the dangers of women in power.
