Au début des années 1970, les travailleurs de l'amiante de Thetford Mines et d'Asbestos ont entrepris un combat pour assainir leurs milieux de travail et leurs villes, dans lesquelles les mines étaient imbriquées. À Thetford Mines, ils ont mené une longue grève de sept mois et demi qui a conduit à la mise sur pied du Comité d'étude sur la salubrité dans l'industrie de l'amiante, puis, avec l'élection du jeune Parti québécois, à la Loi sur la santé et la sécurité du travail qui introduisait les principes de l'élimination des dangers à la source et de la participation des travailleurs à son application. La crédibilité de leurs syndicats s'en trouvait renforcée. Mais bientôt la montée d'un mouvement international visant à bannir l'amiante et la crise économique du début des années 1980 allaient porter un dur coup à l'industrie et entrainer un déclin que rien ne pourrait arrêter. Les travailleurs miniers, qui s'étaient unis contre leurs employeurs et parfois contre l'État dans leur combat pour la santé, s'allièrent dès lors à leurs entreprises et aux pouvoirs publics pour promouvoir le minéral et tenter de préserver leurs emplois et la vitalité de leurs régions. Ils n'ont jamais envisagé l'arrêt de la production d'amiante car ils ont toujours considéré qu'il est possible d'en maitriser les risques et ils défendirent bec et ongles leur produit en arguant du caractère sécuritaire de ses utilisations modernes, malgré un consensus international grandissant à l'encontre de cette thèse. / The asbestos workers in the cities of Thetford Mines and Asbestos launched a campaign for better working conditions and healthier living conditions despite the entanglement of the mines in the heart of their cities, in the early 1970s. The unions in Thetford Mines together led a long, seven-and-a-half month strike, which culminated with the establishment of a committee on hygiene in the asbestos industry (Comité d’étude sur la salubrité dans l’industrie de l’amiante), and then, with the election of the young Parti Québécois, with a new occupational safety and health law which implemented the principles of eliminating dangers at their source, as well as that of worker participation in the endeavour. The asbestos unions had become credible political players. But the rise of an international movement to ban asbestos, along with the economic crisis of the early 1980s, dealt a crushing blow to the industry from which it would never recover. The miners, who had come together to take on their employers - and the government in some cases – to better their health, soon sided with industry and the public authorities to promote asbestos as a way to preserve their jobs and the life of their surrounding areas. They had never considered ceasing asbestos production because they believed the hazards could be controlled, and they persisted in their steadfast defense of the safety of the product even as an international consensus formed against this thesis.

he master’s thesis consists of a case study of an observation tower design made of glue laminated timber and steel. There are two different tower shapes of anchored or free standing tower and these towers are compared. One of the design is chosen and elaborated into final detailing. A short review of main issues bound with the observation towers is given. The review deals mainly with loading (mainly priniples wind loads are analised) and evaluating of towers (ultimate limit states, service limit states and acceleration comfort). The height of final construction is up to 60m. The design is formed by a space lattice structure made of glue laminated timber and steel members of different class. The members are fastened mainly by means of dowel joints with slotted-in-plates . There is a light steel stairway inserted into the main structure.

From RNA-to-protein, translation initiation and protein synthesis is mediated by trans-acting factors that recognize mRNA features common to almost all eukaryotes. Eukaryotic translation initiation factor 3 complex (eIF3) is a highly conserved protein complex that recognizes 5'-CAP elements of the mRNA to initiate translation. eIF3 consists of nine subunits, three of them having two isoforms: eIF3A, eIF2B1, eIF3B2, eIF3C1, eIF3C2, eIF3D, eIF3E, eIF3F, eIF3G1, eIF3G2, eIF3H and eIF3K. This work deals with functional characterization, expression and subcellular localization of eIF3B1, eIF3B2 and eIF3E in Arabidopsis thaliana male gametophyte and interaction of eIF3E with the Constitutive photomorphogenesis 9 (COP9) complex as a regulatory complex of eIF3E post-translational control. Here we show that depletion of eif3b1 or eif3b2 is not gametophytic lethal and that the two protein might function redundantly, whereas, knockout of eIF3E causes male gametophyte lethality. Interestingly, eif3b1 show post-fertilization defects during embryogenesis, suggesting that its redundancy with eIF3B2 is restricted to the gametophyte. Gene expression studies revealed high expression of eIF3 subunits in actively dividing zones of leaf primordia, root meristem and root elongation zones as well as in the vegetative...
