A proposition of an authoring tool, for pedagogical scripting, adapted to teachers
IMANE RYANE,MOHAMMED KHALIDI IDRISSI,SAMIR BENNANI
International Journal of Engineering Science and Technology , 2011,
Abstract: Pedagogical scripting allows teachers to better plan their courses. There are many authoring tools that help in pedagogical scripting. However these tools are little used by teachers, because they are based on complicated educational modeling language (EMLs) like IMS-LD, and don’t offer any support mechanism for the designtask. Therefore we designed an intuitive authoring tool that allows the creation of scenarios, according to an EML easy to learn for teachers, and with a high level of support. This design assistance is provided through a bank of scenario models, and a repository of best practices in education. This repository is a set of rules to follow in teaching, and that the scenarios created with our tool should verify. The validation of a scenario, according to this repository, is done at the request of the designer, once the design is complete, so as not to limit his creativity. The bank of scenario models will enable designer to choose the scenario model the most adapted to his pedagogical strategy, and to the learning situation that he wants to plan.
Effets de deux séquences didactiques sur la production écrite d’un texte informatif (documentaire) en FLE : cas d’apprenants de première année moyenne

Abstract: En fran ais langue étrangère, la production écrite est une activité permanente au cours du processus d’apprentissage. Son enseignement est influencé par plusieurs recherches notamment en linguistique textuelle et en psychologie cognitive qui ont mis en évidence le fait que l’activité de lecture/compréhension peut renforcer celle de l’écriture de différents types de textes dont le texte informatif qui nous intéresse car il constitue, d’une part, un moyen important de découverte du monde et d’enrichissement des connaissances ; d’autre part, nous avons constaté que ce type de texte se réfère à un contenu peu familier aux jeunes apprenants de 1.A.M. Partant de ce postulat, nous faisons l’hypothèse que la production écrite d’un texte informatif pourrait être favorisée par deux activités : tri de texte vs questionnaire, issues respectivement de la linguistique textuelle et de la psychologie cognitive. Notre objectif est donc de repérer quelle est l’activité qui aide le plus efficacement les apprenants de première année moyenne à produire des textes informatifs

Abstract: Recently, lanthanum oxide doped by group IIA elements may strongly influence solid state reaction. A series of samples, noted LaSrX (where X = % atomic of strontium) have been prepared by hydrolysis, in neutral medium from La2O3 and SrCO3. These samples were calcined under air at 450?C and 1150?C then characterized by specific surface area (BET), X-ray diffraction, scanning electron microscopy (SEM), thermogravimetry (TG) and differential thermal analysis (DTA). Obtained results show that after calcinations at: 1) 450?C, the addition of strontium is without effect on surface of La2O3 and the XRD analysis revealed no interaction between lanthanum oxide and strontium carbonate; 2) 1150?C, the sintering of the samples is very important, reduction of 70% of surfaces compared to the samples calcined at 450?C; XRD results show that LaSrX are formed principally by two oxides: SrLa2O4 and La2O3, which is confirmed by SEM method. The reaction between La2O3 and SrCO3 showed three endothermic weight losses; elimination of water, a partial dehydroxylation of La(OH)3 and formation of La2O2CO3 and La2(CO3)3.
DETERMINATION DES METAUX LOURDS PAR VOIE ELECTROCHIMIQUE
Imane ADRAOUI,Aziz AMINE
Technologies de Laboratoire , 2007,
Abstract: La contamination de l’environnement par les métaux toxiques est actuellement un problème majeur. Il en résulte une demande croissante en moyens d’analyse de polluants métalliques, présents dans l’environnement à des niveaux de traces et d’ultra–traces (10-12 -10-7 moll-1). La détermination des métaux lourds par voie électrochimique a connu un essor important au cours de ces dernières années. Cette détermination s’articule autour de trois étapes ; i) étape de préparation des électrodes à flm métallique à base de mercure, bismuth et or ; ii) étape de préconcentration du métal à analyser à la surface flm métallique; iii) étape de redissolution et de quantifcation du métal par balayage de potentiel et mesure d’intensité au potentiel approprié.

Abstract:

Multiple myeloma, a disease of elderly, is extremely rare in those about 30 years of age. A patient with MM diagnosed at age 27 is described. He was a male with a four-month history of back pain and later, hemurus and tibia pain persisting despite NSAIDS. X-rays had shown lytic lesions on lateral radiograph of the skull and the humerus. His ESR was 120 mm. Serum calcium was 125 mg/l and glomerular filtration rate at 25 ml/min. There was a beta2 peak in the serum protein electrophoresis. The Immunohistochemical examination demonstrated a strong reaction for the Lambda light chain in all tumor cells. Bence Jones protein was present in urine. Bone marrow biopsy confirmed the diagnosis of multiple myeloma. Our patient was treated with dexamethasone, zoledronic acid, cyclophosphamide and thalidomide with good evolution. Actually, he was proposed for stem cell transplantation. This report illustrated that multiple myeloma should be even evoked in young patients.

Abstract:

Adenoid cystic carcinoma (ACC) of the breast is a rare type of primary breast cancer with a favorable prognosis, despite its triple-negative status. There has been no consensus regarding treatments. We will report a case of Adenoid cystic carcinoma of the breast presented with localized disease and no axillary lymph node metastases. We performed a radical mastectomy with axillary lymph node dissection, with a favorable clinical course and we will describe the clinic pathologic features of ACC of the breast and review the current literature.

Abstract: The traditional combinatorial designs can be used as basic designs for constructing designs of computer experiments which have been used successfully till now in various domains such as engineering, pharmaceutical industry, etc. In this paper, a new series of generalized partially balanced incomplete blocks PBIB designs with m associated classes (m = 4, 5 and 7) based on new generalized association schemes with number of treatments v arranged in w arrays of n rows and l columns (w ≥ 2, n ≥ 2, l ≥ 2) is defined. Some construction methods of these new PBIB are given and their parameters are specified using the Combinatory Method (s). For n or l even and s divisor of n or l, the obtained PBIB designs are resolvable PBIB designs. So the Fang RBIBD method is applied to obtain a series of particular U-type designs U (wnl;\"\") (r is the repetition number of each treatment in our resolvable PBIB design).

Abstract: Mirizzi syndrome is a rare complication of gallstones with an incidence of less than 1% per year in Western countries. Imaging and endoscopy play a key role in its diagnosis. CT scan helps to eliminate any malignant lesion of the bile ducts or liver hence comes in handy in the confirmation of Mirizzi syndrome. We hereby report a case of a Mirizzi syndrome complicating acute cholecystitis in a 41-year-old patient without any history of disease.

Abstract: Background Bat pups produce individually distinct isolation calls to facilitate maternal recognition. Increasing evidence suggests that, in group-living bat species, adults often use similar calls to maintain contact. We investigated if isolated adults from all three species of the highly cooperative vampire bats (Phyllostomidae: Desmodontinae) would produce vocally distinct contact calls when physically isolated. Methods/Principal Findings We assessed variation in contact calls recorded from isolated captive and wild-caught adult common vampire bats (Desmodus rotundus), white-winged vampire bats (Diaemus youngi) and hairy-legged vampire bats (Diphylla ecaudata). We compared species-typical contact call structure, and used information theory and permuted discriminate function analyses to examine call structure variation, and to determine if the individuality of contact calls is encoded by different call features across species and populations. We found that isolated adult vampire bats produce contact calls that vary by species, population, colony, and individual. However, much variation occurred within a single context and individual. We estimated signature information for captive Diaemus (same colony), captive Desmodus (same colony), and wild Desmodus (different colonies) at 3.21, 3.26, and 3.88 bits, respectively. Contact calls from a captive colony of Desmodus were less individually distinct than calls from wild-caught Desmodus from different colonies. Both the degree of individuality and parameters encoding individuality differed between the bats from a single captive colony and the wild-caught individuals from different groups. This result is consistent with, but not sufficient evidence of, vocal convergence in groups. Conclusion Our results show that adult vampire bats of all three species produce highly variable contact calls when isolated. Contact calls contain sufficient information for vocal discrimination, but also possess more intra-individual variation than is required for the sole purpose of identifying individuals.

Abstract: Introduction: Mucinous tubular and spindle cell carcinomas (MTSCC's) are recently described rare type of renal cell carcinoma (RCC). They may have morphological similarities to papillary RCC (papRCC) and in our case to carcinoma collecting ducts of Bellini. Case report: We report a rare case of renal tumor, mucinous tubular and spindle cell carcinoma in a 56-year-old woman. The tumor, located in the left kidney, was well circumscribed. MTSCC's are characterized by small, elongated tubules lined by cuboidal cells and/or cords of spindled cells separated by pale mucinous stroma. Discussion: MTSCC is a rare type of renal cell carcinoma. Pathologists should be aware of the histological spectrum of MTSCCs to ensure an accurate diagnosis. Careful attention to the presence of a spindle cell population may be helpful in the differential diagnosis in tumors with predominant compact tubular growth.
