Cette présente recherche s’inscrit dans le domaine de la didactique des langues étrangères Elle à pour thème l’application des concepts de la pédagogie inversée dans l’enseignement /apprentissage de l’oral chez les apprenants de 2AM. L’objectif de cette recherche est de vérifier l’impact de cette dernière sur la prise de parole chez l’apprenant. L’utilisation de l’expérimentation et l’observation de classe comme outils d’investigation nous aurait permis de relever les indicateurs qualitatifs et quantitatifs relatifs à l’analyse des données et à la validation de notre hypothèse de recherche.

Dans ce travail, l'hydroxyapatite (HAp) a été synthétisée et appliquée pour éliminer le colorant bleu solophényl (BS) d'une solution aqueuse. Les propriétés physico-chimiques de l'HAp ont été caractérisées par la spectroscopie infrarouge et par la méthode BET. Plusieurs paramètres ont été optimisés tel que le pH initial, la masse de l'adsorbant, la concentration initiale du colorant, le temps de contact et la température pour éliminer le BS d'une solution aqueuse. La cinétique de l'adsorption a montré que l'équilibre est atteint au bout de 40 minutes avec un taux d'élimination de 98,5% pour une masse d'adsorbant de 0,06 g et un pH égale à 6. Les études cinétiques et isothermes ont montré que l'adsorption du BS suivait le modèle de pseudo-second ordre et l'isotherme de Langmuir s'est avéré être le modèle le plus approprié. L'étude thermodynamique a révélé que l'adsorption est spontanée, endothermique et de nature physique.

Family of coronavirus has significant human and animal pathogens. At the end of December 2019, a novel coronavirus was recognized as the reason of a group of pneumonia cases of unidentified etiology. The novel coronavirus has quickly become widespread, resulting in an epidemic throughout China, followed by a pandemic, an increasing number of cases in various countries throughout the world. The CCL2 is the prominent chemokine linked to COVID-19 severity. Other chemokines such as CCL5 and CXCL10 may be elevated in patients with COVID-19.Ninety blood samples were taken from clinically diagnosed patients infected with COVID-19 virus divided in to (45) with severe infection and (45) with mild infection. The samples were taken from both sexes (51) males and (39) females at age ranged between (20-80) years old attending to Al Zahraa Hospital of Imam AL-Hussein Medical City, Karbala /Iraq during the period extended from October (2020) to February (2021).The CCL 2, CXCL 10, and CCL 5, were measured and recorded by ELISA. The complete blood count, C-Reactive Protein, Ferritin, and D.dimer, were measured and recorded by swelab alfa complete blood count analyzer, antigen antibody agglutination reaction, and Enzyme Linked Fluorescent Assay analyzer, respectively. All patients were taken with positive Polymerase Chain Reaction (PCR).In this study observed role of different laboratory data and immunological Markers. The mean of C-Reactive Protein in severe patients was significantly higher (P=0.000) than in mild patients, (136.44) and (16.53), respectively. The mean of serum ferritin mean among mild patients (114.98) compared to (1018.27) for severe patients group, showing a significant association with severe patients (P=0.000). The mean of D.dimer showing a higher significant association with severe patients group, giving to a mean of mild groups (303.13) and (1049.56) among severe groups (P =0.000). Monocyte Chemotactic Protein 1(MCP-1) or CCL2 mean among mild patients (405.39) compared to (857.99) for severe patients group, and showing a significant association with severe patients (P=0.000). Another marker with important role as biomarker severity for COVID-19 is the Interferon Gamma Induced Protein 10kDa (IP-10) or CXCL10, in severe patients was significantly higher (P=0.000) than in mild patients, with mean (453.80) and (243.17), respectively. A Chemokine (C-C motif) ligand 5 or CCL5 showing a significant association (P=0.000) between severe patients group, giving to a mean of mild patients (594.86) and (1300.70) among severe patients group.The results of this study have shown an elevated serum levels of CCL2, CCL5 and CXCL10 in severe group compared with mild group of COVID 19 patients, therefore, these markers might have an important role in the severity of COVID 19 infection.

Ce projet consiste à faciliter le processus de mesure de différentes conditions(température, niveau, courant, et tension…etc.) et améliorer l’acquisition des données du banc didactique de pompe à chaleur (Mod.F-PC/EV).Ce mémoire nous permet de plonger dans le domaine d’instrumentation et d’acquisition de données afin d’arriver à réaliser un data logger qui communique entre (l’unité de pompe à chaleur et la carte Arduino ainsi que les différents capteurs.)L’objectif préliminaire est de manipuler un langage et programmation (Arduino IDE) et transmettre les résultats de mesure vers un pc via un câble USB et vers un afficheur LCD

Background and aims: Inflammatory bowel disease, a diseasepreviously thought to afflict predominantly people of western countries,has not gained the awareness and publicity among Sudanese cliniciansand pathologists. The aim of this study is to enlighten this dark area andprovide some epidemiologic, clinical and pathologic data oninflammatory bowel disease in Sudanese patients.Methods: Patients diagnosed with inflammatory bowel disease at SobaUniversity Hospital in the period 2006-2010 were retrospectively selectedfor the study. Clinical and endoscopic data were collected. Tissue blockswere retrieved and processed into H&E slides. The slides were reviewedand our observations compared to those on the original histopathologyreports. Any discrepancy between the two made the case excluded. Allthe data thus obtained was compiled into a checklist for each individualcase and analysed electronically.Results: Seventy two cases of inflammatory bowel disease were found inthe study period, 42 (58%) with ulcerative colitis, 15 (21%) with Crohn’sdisease and 15 (21%) with a label of indeterminate colitis. More caseswere diagnosed in the last three years of the study compared to the firsttwo. The age range was 14-87 years with the peak for ulcerative colitisVIIbetween 51-60 years and for Crohn’s disease between 31-40 years.Seventy two percent of the study population were males with a higherobserved prevalence among males for both ulcerative colitis and Crohn’sdisease. Seventy percent of the cases were from patients residing atcentral relatively more urbanised areas of the country. A third of the casesof Crohn’s disease were diagnosed from resection specimens compared tonone of ulcerative colitis cases. Granulomas were demonstrated in 60%of Crohn’s disease patients compared to only 2% of ulcerative colitiscases. Further, granulomas in Crohn’s disease patients were morefrequent in resection than in biopsy materials. Dysplasia was found in12.5% of the whole study population. Among patients with ulcerativecolitis and Crohn’s disease, dysplasia was found in 19% and 7%respectively. However, the association between frequency of dysplasiaand disease duration was difficult to estimate because of paucity of data.Conclusion: The number of new inflammatory bowel disease cases is onthe rise. A high volume of cases diagnosed as indeterminate colitis isnoted. Well designed epidemiologic studies are needed to verify theissues of disease locales and the relation of disease duration to thefrequency of dysplasia.
