The current study sought to understand the professional goals of female students doing a master's degree in ELT. In particular, this study aimed at exploring female students' initial expectations in the implemented ELT programme at SQU in terms of the courses' content and materials as well as their pedagogical design and implementation, and whether these expectations have been met. Semi-structured interviews were conducted with six female students, including four females who completed 24 credits of the coursework which is the total number of required credits in the M.Ed. ELT programme at SQU and currently working on their thesis as well as two females who graduated from the same programme. A descriptive phenomenology approach was adopted, and a thematic analysis was utilized to analyse the data obtained from semi-structured interviews. The findings suggested that all participants were highly critical of the programme as being outdated, theory-based and lacking the practical component. They came with high expectations that the syllabus would help them to overcome the contemporary challenges of ELT in Oman and expose them to the current practices in the field. Moreover, all participants were critical of the design and availability of the materials. They indicated that some materials were outdated, focused on theoretical aspects, lacked practical aspects, and encouraged rote learning. They further indicated that some courses lacked authentic materials. They additionally reported that these materials were inadequate to prepare them as researchers. Furthermore, the findings revealed that some participants seemed satisfied with formative assessment, while others were highly critical of the summative assessment adopted in some courses and which mainly focused on rote memorization. Besides, all participants believed that instructors were experts, competent, knowledgeable, and dedicated but there were complaints about their feedback and their teaching styles. It was found that lecturing was the dominant teaching method in the programme and many of the participants also reported a lack of technology use. Moreover, results indicated that instructors' feedback about students' performance was almost completely overlooked in the courses. Based on the findings, practical implications and suggestions for future improvement have been outlined.

This study was carried in the period from December 2002 to February2003. A total of 49 blood samples werecollected from mycetoma patients inMycetoma Research Center – Soba Civil Hospital and National Healthlaboratory (ESTAC)- Khartoum State. The group surveyed included: 17(34.7%)infected untreated or new patients, 32 (65.3%)infected treated patients, andnormal control group (16 individual).The study showed that males were more affectedthan females and theratio was 4:1. Most of mycetoma patients werein the age group 15 – 25 yearsold. Students (20.4%), jobless (18.4%) and farmers (14.3%) were moreaffected than other occupations. Algazera State had a highest prevalence ofmycetoma with (34.7%); next state was Khartoum State (16.3%).The duration of the disease varied from 7 month to 30 years and theonsets of the disease in most of patients (73.5%) had no known history oftrauma. Left foot was the major site of infection (34.7%) and most of patients(83.7%) had no family history of mycetomainfection. Eumycetoma infectionhad higher prevalence (59.2%) than actinomycetoma infection (38.8%).The drug used for treatment in eumycetoma infection was ketoconazole,and in actinomycetoma was a combination of Streptomycin, Septrin and folicacid.Total white blood cells in most of patients (44.9%)were normal countbetween 4050 - 6000cells ⁄µl. and the mean value in untreated patients was6081.5cells ⁄µl, while in treatedpatients it was 6178.3cells ⁄µland in non-infected control it was 570.9 cells/µl.

Le Présent mémoire tend à révéler le concept de qualité, de coût et de délai pour les marchés publics en Algérie ainsi qu’identifier leurs exigencesen matière deprocédures et de documents constituant un contrat de commande publique dans le domaine de la production architecturale. Pour ce faire, l’enchaînement des idées a commencétout d’abord par la construction d’une base de données sur le triptyque : qualité, coût et délai, ensuite l’exploration de notre champ de recherche par l’explication des marchés publics dans le but de mieux comprendre le contexte contractuel. Il a été, ensuite, question d’établir le lien entre les informations récoltées en repérant la qualité, le coût et le délai dans les marchés publics. Et enfin, l’application des connaissances acquises sur le cas d’étude qui est le nouvel hôpital 240 lits à Ain M’lila.À l’aide d’un questionnaire destiné aux professionnels et aux agents exerçant dans le domaine, la recherche a tenté d’apporter une réponse à l’unedes questionsprincipales sur l’importance accordée par la règlementation des marchés publicsaux notions de qualité,de coûtetde délai.Pour aboutir en fin de compte à un projet dans le secteur sanitaire « Hôpital Mère-Enfant » à la ville de Ain M’Lila, où on a essayé de créer un équipement réconcilié tant avec son contexte urbain que règlementaire.

Les catalyseurs à base de fer et du cuivre sont des systèmes catalytiques très actifs dans la réaction de conversion du 4-nitrophénol en 4-aminophénol. Dans ce cadre, deux types de catalyseurs à base de fer et du cuivre : supportés, Fe/NaX et Cu/NaX, oxydes, α-Fe2O3 (naturelle et synthétique) et Cu/α-Fe2O3, ont été proposés et leurs propriétés physico-chimiques, acido-basiques et catalytiques ont été étudiées et comparées. La réactivité de nos catalyseurs a été testée dans la réaction de réduction du 4-nitrophénol en présence de NaBH4 à une température ambiante. Les résultats obtenus ont montré que ces différentes propriétés sont très influencées par le type de solide (supporté ou massique), la nature de l’oxyde (naturel ou synthétique, simple ou mixte), la méthode de préparation, la teneur en cuivre et le traitement thermique. Les meilleures performances catalytiques dans réduction du 4-nitrophénol ont été obtenues sur les catalyseurs Cu/NaX et Cu/ α-Fe2O3 ont conduit à des conversions totales en 4-aminophénol respectivement à 60 s et 50 s.

Tomato yellow leaf curl disease is the most devastating viral disease of tomato and other dicot species caused by Tomato yellow leaf curl virus (TYLCV). TYLCV is a whitefly (Bemisia tabaci) transmitted geminivirus belongs to the family Geminiviridae, genus Begomovirus. The management of the disease in Oman is mainly based on cultural practices and use of pesticides, which is not sufficient to reduce disease incidence. The deployment of host-plant resistance is the most practical mean to control this disease.MicroRNAs (miRNAs) are short 21 to 23 nucleotide long RNA sequences homologous to target viral Rep sequences with important regulatory role. miRNAs control the expression of target transcripts by binding to complementary sequences leading to cleavage or translational inhibition of the target RNA. Plants carrying sense or antisense transgenes can exhibit spontaneous silencing.To achieve this goal, sense and antisense transgenes derived from Rep (replication associated protein) ORF of TYLCV-OM driven by 350S CaMV promoter and Nos terminator were synthesized commercially. Susceptible tomato cultivar (Moneymaker) was used as explants and co-cultivated with Agrobacterium tumefaciens strain AGL1 harboring plant expression binary vector carrying miRNA gene. Transformed shoots were selected on kanamycin medium and the presence of the transgene in the primary transformants was confirmed by PCR using CaMV promoter specific primers. Seeds were collected and sown. Integration of amiRNA genes into F1 transgenic plants was confirmed by PCR. F1 tomato seedlings were challenged with TYLCV-OM.Putative transgenic plants obtained through Agrobacterium mediated transformation have 70% transformation efficiency. Seeds from transgenic plants have been collected to test resistance against TYLCV-OM in F1 generation. Severe disease symptoms of TYLCV infection appeared on susceptible tomato plants whereas no symptoms developed on transgenic plants.The findings of this study were consistent with previous studies demonstrating amiRNAmediated resistance is an effective silencing strategy to introduce anti-viral transgenes in host plants. Transgenic expression of Rep-specific amiRNAs was found to be an effective method to inhibit TYLCV infection in tomato plants.

Lebanon’s transportation sector has always experienced decades of deterioration and chaos due to political and administrative instability, limited investment, and more importantly the absence of a standardized public transit mapping system. Despite the sector’s importance in everyday commuting and the several reformative initiatives proposed over the years, it remains in an unstable and outdated state of decay and disorder. This thesis addresses the need for an organized and inclusive mapping system by proposing a human-centered schematic prototype for the Lebanese transit sector. The design is built on a hybrid grid system strategy that combines regular and adapted octo linear structures with a curvilinear grid, and is grounded in principles of schematization, wayfinding semiotics, and inclusive transit design strategies. The research incorporates extensive archival analysis, field observations, stakeholder interviews, and contemporary data collected from academic and governmental institutions involved in public transit. The resulting prototype and mobile user interface are evaluated through usability observations and iterative testing to assess their accessibility and wayfinding performance across diverse transportation settings. The outcome proposes a reformative mapping strategy branded and adapted to Lebanon’s public transit infrastructure and the needs of its daily commuters.
