Texto completoWood experiences a growing demand as a construction material in tall buildings. Its aesthetic qualities and the fact that it is a renewable material make it attractive for architects. When compared to functionally equivalent products, it appears that the wood decreases non-renewable energy consumption and total energy demand. Plus, wood carbon storage can reduce the environmental footprint of buildings when compared to steel or concrete. Now allowed up to six stories high in Canada, tall wood buildings are matter for important design challenges. When designing structures, the connector areas are often the critical points. Indeed, the stresses are highest there. Thus, the structures tend to appear massive and to reduce architectural innovation. New strategies need to be developed to improve the mechanical strength in the connector zone. Various studies have recently brought on creating or improving assembly type. In this study, the aim is to target the material used in the connection area by reinforcing it. The impregnation was chosen as the strengthening solution since the literature demonstrates that it is possible to increase the wood hardness with this technique. The use of this treatment on black spruce (Picea Mariana (Mill.) BSP) as a structural application is the novelty element in this research. Despite a full piece impregnation, the low permeability wood species helped to create a thin layer of densified surface without having to use a large quantity of chemicals. A vacuum-pressure impregnation process was used to develop a new wood-based material more performant in assemblies. The impregnation agent was composed of 1,6 hexanediol diacrylate, trimethylolpropane tricacrylate and of a polyester acrylate oligomer. A second formulation containing SiO2 nanoparticles allowed to verify the effect of the nanoparticles on the treatment. The dowel-bearing strength test was performed to determine the contribution of the treatment on the wood used as a connector element. The scale effect was observed by performing the test with three different diameters of bolts (9.525 mm, 12.700 mm and 15.875 mm). In addition, the test was carried out according to a load applied in the perpendicular to grain direction for the mean diameter of bolt (12.700 mm). The digital image correlation was used while executing the dowel-bearing test as an analytical tool to compare the differences between strain fields before and after the reinforcement treatment. Results have shown higher bearing strengths after treatment. Furthermore, the efficiency was increased more the bolt diameter decreased. The best results were defined as a 79% greater dowel bearing strength for the characteristic value using the bolt of 9.525 mm. The stiffness of treated wood was higher of approximately 30%. Better mechanical performances after treatment are associated to the increase of density giving by the polymerization of formulation at the border of the bolt hole. Change in dowel bearing strength was almost nonexistent for the perpendicular to grain orientation. Low depth penetration due to the wood anatomy limiting the permeability in the perpendicular to grain direction caused this phenomenon. For the treated sample, the presence of a cracking failure was less common. With the digital image correlation analysis, the strains were found to be distributed more widely around the connection area. Also, no significant differences were found in the samples treated with and without nanoparticles. A slightly lower chemical retention was observed for the treated with nanoparticles sample group due to the accumulation of nanoparticles acting as a barrier at wood surface. Normally, this could lead to better densification of the external layer of the wood, but in this case mechanical performances were the same. There is no need to add nanoparticles and increase the cost of chemicals. Despite a very low penetration of the liquid inside the timber, the densified layer created at wood surface is suitable to produce a new, strong material in the connecting areas. The reinforcement of wood in connectors region could influence the design of large structures. With strengthen connection elements, it would be possible to extend the beams spans, thus multiplying the architectural possibilities. The reinforcement could also reduce the sections of beams and decrease the need in construction materials. This would result in diminished transport costs and faster assembly times. In addition, a fewer quantity of connector elements could be needed, reducing the supply costs in metal elements as well. The outcomes of a new and more efficient wood-based material used in connections would promote wood in tall buildings while helping to lower the environmental impact of buildings.

Texto completoSince its independence in 1958, the Republic of Guinea has experienced three regimes of government. During the First Republic, many reforms were introduced to promote the democratisation of education. Following the inauguration of the Second Republic in 1984, the new authorities identified serious distortions in the education sector with a weakness of financial viability and adopted a new policy. The objective of the democratisation of education remained the same, but the number of higher education institutions was drastically reduced The criteria for student acceptance became stronger and the number of students shrank. Current research work has been based on a recognition of the present inability of the government to meet a strongest demand for higher education. The objective is to develop a complementary solution which preserves, and improves the quality of teaching, in the context of a shortage of resources, by the distance learning. Following a initial approach of distance learning, a deeper study of both the social-economic and educational contexts has given a better understanding of pressures for a wider access to university. From this analysis originated the concept of a Cooperative Centre of Higher Education of Distance Learning based on a federation of the former establishments to provide improvements in the reception of students and opportunities better adapted to meet both the needs and the social- economic imperatives of Guinea

Texto completoSalt stress is one of the main environmental factors limiting plant growth and yield in cereal crops. It is therefore imperative to develop varieties more tolerant to salt stress in order to increase yield and ensure food security. The signaling pathway linking salt stress perception to cellular response was addressed here by studying RSS1-like proteins in plants. RSS1 (Rice Salt Sensitive 1) protein plays an important role in salt stress tolerance. It acts at the interface of stress perception and developmental control and division in meristems. During this work, the RSS1 counterpart named TdRL1 (Triticum durum RSS-Like 1) was isolated from the durum wheat Tunisian variety "Oum Rabiaa". We have demonstrated that TdRL1 carries the conserved D and DEN-Box motifs involved in the post-translational regulation of the protein. In addition, we show that TdRL1 is the functional homologue of RSS1 since it was able to complement the loss-of-function mutant rss1, hypersensitive to salt stress. In addition, heterologous expression of TdRL1 enhances salt stress tolerance in yeast and in Arabidopsis by increasing germination and reducing the accumulation of reactive oxygen species. Our cytological studies have shown that the TdRL1 protein is cytoplasmic in interphase and is localized at the spindle during mitosis. Remarkably, TdRL1 changes its subcellular localization under salt stress treatment and shows a partial accumulation in the nucleus, highlighting the multifunctional nature of this protein during salt stress response. Our data suggest that under salt stress, TdRL1 plays a role in the regulation of the cell cycle in relation with the microtubule network. Pursuing the study of RSS1-like multifunctional proteins will open up new research areas for the creation of wheat varieties that are more resilient to environmental stresses

Texto completoIntroduction: Maintaining physical activity is essential to maintain the benefits of multidisciplinary care. However, chronic low back pain patients are not well prepared foran independent approach. It is necessary to support them in this process of behavioral change in order to bring them to regular physical activity.Objective: The main objective was to determine strategies for improving physical activitycompliance with chronic low back pain patients.Method: 3 studies have been conducted. The first one has searched to determine theeffectiveness of a short physical activity program, outside the care structure, for chroniclow back pain workers. The second one has consisted of the evaluation of an educationprogram added to the multidisciplinary management on the compliance in physicalactivity of chronic low back pain patients. The third one has consisted of establishingisometric muscle norms on healthy subjects.Results/conclusion: These studies have shown the benefits of physical activity in themanagement of chronic low back pain, both on pain and on functional and psychologicalparameters. However, the practice of physical activity alone does not make it possible tomodify patients' behaviors. The implementation of a education program leads to asignificant improvement in compliance with the treatment program and physical activity,although this remains moderate. However, these studies have made it possible tounderstand the complex nature of the behavioral changes that can lead patients with lowback pain to adopt an active lifestyle

Texto completoMaritime pine (Pinus pinaster Ait.) is one of the main economical forest species in France, providing about twenty five percent of the national round wood production. A breeding program, implemented since the 60’s, offers genetically improved varieties for growth and stem straightness.This PhD explores the use of molecular markers in breeding strategies for maritime pine in Aquitaine. Molecular markers were used for pedigree recovery in a polycross progeny trial to test assumptions of backward selection on one hand, and to evaluate the feasibility of a new breeding strategy on the other hand. First, the pedigree of 984 progeny was recovered with 63 SNPs allowing to verify the assumptions of backward selection. We also showed that genetic parameters and maternal breeding value estimates were not much modified by inclusion of full pedigree information. Then, the best progenies in the polycross trial were preselected and genotyped to investigate the possibility of carrying out a forward selection strategy. Finally, establishment of clonal seed orchards were simulated from various breeding strategies (backward, forward, mixed) in order to compare genetic gains from the improved varieties obtained thereby.This study opens new perspectives towards an implementation of forward selection in the French maritime pine breeding program, to speed the selection cycles up and to increase the frequency of variety renewal. Moreover, the set of SNP markers developed is now used in different steps of the breeding program

Texto completoAdditive manufacturing of metallic parts has gained significant popularity in recent years as an important technological solution for the production of complex parts. Among the different processes of metal additive manufacturing, the wire-arc additive manufacturing (WAAM) using CMT (Cold metal transfer) welding is taken for our study because of its high deposition rate, low cost of equipment and little loss of material (low spatter) during manufacturing. In the literature review, it can be noted that one of the most important problems that prevent the industrial application of the WAAM is the poor geometric accuracy of the manufactured parts due to the instability of the process and the lack of reliable control system to deal with irregularities during deposition. The focus of this work is to improve the stability and geometric performance of the process. In this work, an experimental system is implemented to robotize the process and to monitor the geometry of the deposited parts. The process is modeled by artificial neural networks and a control system is developed to regulate the geometry of the deposit and to reduce manufacturing errors. Furthermore, an improvement strategy is applied in order to reduce the geometric instabilities at the ends of the bead; an in-situ monitoring method is also developed to detect the internal defects of deposited parts

Texto completoThe coconut selection scheme developed by the Institut de Recherches pour les Huiles et Oléagineux is based on the constitution of a collection containing numerous ecotypes, then detection and improvement of the best hybrid combinations between ecotypes. We have undertaken a general overview in the aim of definiting how best to proceed with coconut improvement. After taking stock of breeding work throughout the world, we analysed the latest data available on species variability and on genetic trials conducted in Côte d'Ivoire. This approach enabled us to define thre major lines of research : privileging the collection and assessment of a large number of introductions, furthering genetic recombinations between ecotypes and , finally, preparing the way for the development of vegetative propagation in vitro, which should eventually lead to clone distribution. The method recommended involves two selection channels : improvement of Dwarf x Tall hybrids and of Tall xTall hybrids. It is based on the use of evolutionary testers, chosen so as to retrieve the essential elements of the genetic progress made during previous selection cycles. These testers are initially made up of simple hybrids between the best ecotypes ; selection will therefore concentrate on complex hybrids (three or more parent ecotypes). Tall x Tall hybrids tests will also be used as a genetic combination phase between Tall ecotypes, which will enable considerable savings to be made in both time and resources. The main risk in our method lies in the existence of high variability within the progenies tested, but this risk mainly involves the Tall x Tall hybrids. In additon, as soon as selection is based on individuals, this risk will be much reduced. Finally, within-progeny variability will provide for effective clonal seletion as soon as the in vitro vegetative propagation method has been perfected. The selection method proposed seems to be especially adapted to the launching of a new improvement programme. It should meet the requirements of breeders, who are keen to exploit rapidily the variability of ecotypes in their country, but who whish to benefit from the considerable genetic progress made the forty years of research carried out at the Marc Delorme station
