Dans ce travail, il est formulé des lois prédictives pour l’estimation des pseudo spectres en vitesse, des pics d’accélération de sol et des durées de mouvements sismiques forts. Ces équations prédictives sont élaborées en utilisant des analyses statistiques faites sur la base d’une banque mondiale de données accélerométriques. Les résultats obtenus montrent que les lois prédictives proposées sont particulièrement intéressantes pour la prédiction réaliste de la réponse des structures et de l’intensité des mouvements forts de tremblement de terre futurs.

Hasil nilai pada kemampuan berbicara (6,413), > t- table (2,05/2,76).) ini menunjukan adanya efektifitas penggunaan media Strip Story dalam memperbaiki keterampilan berbicara bahasa Arab siswa. Berdasarkan hasil penelitian ini, maka hendaknya para peneliti berikut untuk mengembangkan media pembelajaran berbicara yang lain untuk dapat dijadikan perbandingan antara media strip story dengan media pembelajaran yang lain. ABSTRACT Teaching aids that help the teaching and learning process by the effective activites and interesting in using the media a teacher doesn’t choose the teaching aids easy and cheap only, but the teaching aids that gives much benefits in developing the reading learning on the text comprehension and increase the language and language structure. Strip story is one of media/ case from teaching thah help the speaking proess. Ali Ahmed said, this Strip Story is teaching aids a kind of short story card that divided. And this cards is divided of story. The students is asked to arrange the cards to be a story. The research aimed at knowing the effectiviness of strip story teaching aids aplications in improving and developing atudent’s speaking skill of students of Senior high shool Ma’arif Pasuruan East java. The methodology of this research is empirical research used by the researcher to obtain result of the experiment the school year 2012-2013, the researcher discovered teh data through direct observation and interview and test and questionnare. The result of can be concluded that: the test of pretest and post test result for text comprehension in showed that the t-count result (6,413) > t-table (2,05/2,76). So does the result of the tests for speaking skill its mean that there was significant for student’s speaking competence before and after the application of Strip Story.The application of “Strip Story” had effective and significant influence in developing student’s speaking skill. Based on this result research, be desirable that for researchers after this research for expand the speaking teaching aids or other learning, and to compare between the Strip Story Teaching aids and the other teaching aids.

A new series of heterocyclic compounds was prepared via the reaction of different substituted hydrazonoyl chlorides 22, 120 and 121 with substituted aminopyrimidines 122-124. The reaction produced in general a mixture of acyclic products 127, 132b, 136, 137, 139a, 139b, 139c and fused heterocyclic rings 129, 133a, 133b, 140a and 140b.The obtained acyclic adducts compounds 127, 132b, 139a, 139b and 139c are produced as a result of direct attack of the pyrimidine amino groups 122-124 at the electrophilic carbon of nitrilimine. In one particular case the acyclic product 136, 137 was obtained as a result of direct attack of the pyrimidine nitrogen at the electrophilic carbon of nitrilimine. The fused imidazopyrimidine derivatives 129, 133a, 133b, 140a and 140b are obtained as a result of the reaction of the dinucleophilic pyrimidine nitrogen and the amino group at the dielectrophilic carbons of nitrilimine.The obtained products were fully characterized and their chemical structures were confirmed by 1H-NMR, 13C-NMR, MS and HRMS. The structures of compounds 132b and 133b were further confirmed by x-ray.The biological activities of the obtained products were tested and evaluated against Gram-negative and Gram positive microorganisms. The Microbroth Dilution Method was used to evaluate the antibacterial activity and determination of MIC50

L'utilisation des vers de terre comme source alternative de protéines pour l'alimentation des volailles est une opportunité pour fournir des services environnementaux moins coûteuses . Grâce aux vers de terre, les déchets et sousproduits organiques générés par les activités d'élevage peuvent être valorisés et devenir une ressource pour l'alimentation animale dans une économie circulaire. Dans ce contexte, ce travail est mené dans le but d’améliorer les connaissances sur les des vers de terre, et de présenter des pistes pour l’optimisation de l’élevage des vers et la valorisation de ses produits finaux dans l’alimentation des volailles et la fertilisation des cultures. Après un élevage à domicile, les résultats issus étaient encourageants avec un taux de multiplication de 64% preuve de la prolificité et la rentabilité de cette filière. De même, pour une meilleure exploitation de ces ressources, un projet intégral a été proposé et une maquette artisanale démonstrative a été conçue avec un devis des couts attribué par un éleveur de vers de terre. Ce travail est une contribution à la connaissance des vers de terre et aux perspectives de leur valorisation pour l’alimentation animale et l’amélioration des fertilités des sols agricoles.

Tests are familiar in educational field; vocabulary tests have been adopted as measures of general ability or intelligence and as measures of achievement in special subject fields. It has been presumed that vocabulary can be learnt through reading and practicing other language skills. The study aims to :Present with effective techniques for future remedial work, to draw attention of EFL teachers and syllabus designers to the importance of constructing vocabulary tests, to investigate the difficulties facing teachers in testing vocabulary, provide EFL teachers with effective ways of testing vocabulary, and to emphasize the importance of awareness of meaning of the words. The study followed the descriptive analytical method. A questionnaire is used as a means of data collected, it consisted of ten statements then distributed to basic schools in Wed Medani in order to elicit their view. The collection data were analyzed through Statistical Packages for Social Sciences (SPSS) by using tables and graphs. The study comes up with many results, among such: Translating the meaning of the new items into student’s native language interrupts them in testing, More drills and exercises reduce the problems of vocabulary tests, using the new items in various contexts, helps the students to recognize them easily in testing, and adequate recycling of the new item in the syllabus improves the learners’ performance in testing. Upon the previous results the study recommended that students should be exposed to more spelling and testing practice, drills should be designed periodically, teacher at basic level should not present many new items in a limited period of time some of the new items should let for students to guess, students should practice the use of the new items by attempting more drills and exercise, and syllabus designers should be aware of the importance in the student's textbooks.
