Notre travail porte sur les ressources et les connaissances professionnelles des professeurs. Nous nous intéressons en particulier à l'enseignement du nombre à l'école maternelle et considérons le cas des ressources technologiques. Concevoir et mettre en oeuvre un enseignement ayant recours à ces ressources d'une manière qui favorise les apprentissages est complexe et implique sans doute des évolutions dans les ressources, les pratiques et les connaissances professionnelles des professeurs. Notre thèse s'intéresse précisément à saisir ces évolutions et les moteurs de ces évolutions. Nous mobilisons l'approche documentaire du didactique qui nous permet d'envisager l'intégration des ressources technologiques dans le système de ressources des enseignants. Nous articulons à cette approche la notion d'orchestration et analysons les délicates gestions didactiques des ressources technologiques et de ressources tangibles dans les classes de maternelle. Notre travail s'inscrit dans un projet de conception de ressources (projet Mallette, groupe MARENE). Nous suivons sur une durée longue le travail documentaire de deux professeures impliquées dans ce projet.Nous proposons une « plongée » au coeur de la documentation de ces deux professeures. Nous mettons en évidence les articulations entre un système de ressources général et un système de ressources local, lié à l'enseignement du nombre. Nous développons les notions de ressources indispensables et pivots pour penser ces liens. Nous proposons d'y articuler la notion de blocs de ressources situées. Notre étude permet également d'identifier de nouvelles orchestrations spécifiques de l'école maternelle. Elles sont liées à des connaissances professionnelles et des ressources partagées par les professeurs exerçant dans ce contexte (importance de la manipulation en mathématiques, ressources tangibles). Cette étude met en relief des genèses documentaires différentes chez les deux professeures suivies. Nous montrons l'existence de genèses dynamiques dans lesquelles s'entrelacent des processus d'instrumentalisation et d'instrumentation portant sur la conception et la mise en oeuvre d'un enseignement impliquant les ressources technologiques, mais aussi plus largement portant sur l'enseignement du nombre. L'observation des élèves et le collectif sont des moteurs essentiels dans le déploiement de ces genèses. / Our research focuses on kindergarten teachers' resources and professional knowledge. We examine how numbers are taught, particularly with technological resources. Designing and implementing teaching units with these resources, in a fruitful way, is complex, and probably implies that these resources, along with teachers' practices and professional knowledge, evolve. We notably attempt to grasp these evolutions and their impetus. Our theoretical framework mainly refers to the documentational approach of didactics, that allows us to observe how technological resources are integrated in teachers' resource systems. We link up with this approach the notion of orchestration, and analyse the fine didactic management of technological and tangible resources in kindergarten classes. Our study lies within the framework of the research group MARENE, a project on the designing of resources and of the follow-up of their use. Thus, we follow the long-term documentation work of two teachers involved in this project.We propose an « immersion » at the core of these two teachers' documentation activity. We highlight how a general resource system is articulated with a local resource system on the teaching of numbers. We develop the notions of essential ressources and of pivotal resources in order to examine this articulation. We propose to join another notion to these, the notion of set of situated resources. Our research also makes us identify new specific orchestrations at kindergarten school. These are deeply linked to professional knowledge and to resources shared by teachers working in this context (importance, in mathematics, of manipulation, of tangible resources) . We bring out differentdocumentational geneses among the two teachers we follow. We show the dynamic geneses in which the instrumentalisation and instrumentation processes overlap, when it comes to the designing and implementation of lessons including technological ressources, but also, in a broader perspective, as regards the teaching of numbers. The observation of pupils and the collective are essential incentive for the unfolding of these geneses.

Os resultados da avaliação do equipamento nas três bases estudada levaram a concluir que: o equipamento apresentou bons resultados quando analisado como um todo para as base, constatou-se problemas de uniformidade e de eficiência em alguns setores quando a análise foi feita por raio individualmente, indicando setores com déficit e outros com excesso de água, o equipamento apresentou seus piores resultados quando foi avaliado na base 5, verificou-se que existe uma dispersão das lâminas de água aplicadas em relação ao valor médio, em todas as bases estudadas, as pressões de entrada do pivô nas bases, 4 e 5 estão muito abaixo da pressão recomendada o que resultou numa baixa vazão nestas bases. / The objective of this work was to evaluate the performance of a towable pivot center in thefield on Fazenda Capim in the municipal district of Capim-PB. The results of the equipment evaluation of the three studied bases showed that the equipment presented goodresults when analyzed as a whole for them. Uniformity and efficiency problems in some sections were analyzed when the analysis was individually made by ratio, indicating sections with deficit and other with excess of water. The equipment presented their worst results when it was evaluated in base 5. It was verified a dispersion of the applied water sheets in relation to the mean value, in ali studied bases. The pressures on pivot in bases 4 and 5 are a lot below the recommended pressure and resulted in low flow in these bases.

The Master´s thesis is focused on the design and structural analysis of the hall serving for businnes and exhibitons purposes that is strained by the permanent load, climatic and operational load. The construction is located in the area Opava. The hall is designed as intersection of two domes. The diametr of smaller one is 38,0 m and diametr of bigger one is 50,0 m. Maximum high of the construction reach 15,150 m. The main carrier elements of the structure are beams made from glued laminated timber, class GL24h.

The subject of the diploma thesis is design and examination of supporting steel structure of the exhibition pavilion situated at the Brno Exhibition Centre, including a comparison with the second variant. The design emphasis has been placed on keeping the architectural character of building related to its purpose. The structure consists of 11 sections shaped as elliptical arcs, formed by truss frames with variable length of semi-axes, while the largest size (the smallest) is 13 m (7 m) for minor semi-axis and 20 m (14 m) for the main semi-axis, height is 16 m (10 m) and distance of support 38.92 m (25.30 meters). For the analysis of internal forces has been assembled spatial bar shaped model. Cladding is made of Kalzip system.
