Fatigue (physiologie)La fatigue est un état résultant de contraintes physiologiques ou psychologiques aboutissant à une diminution des performances physiques ou cognitives. La fatigue physiologique est réversible avec la mise au repos, qui restaure un niveau normal de performances. La fatigue psychique se manifeste par une baisse de l’attention et de la concentration. Lorsque associée à une pathologie, on parle plutôt d'asthénie. Au niveau sociologique, l’accélération des rythmes de vie inhérents aux sociétés modernes accentue ce phénomène de fatigue.
Construction managementConstruction management (CM) is a professional service that uses specialized, project management techniques and software to oversee the planning, design, construction and closeout of a project. The purpose of construction management is to control the quality of a project's scope, time / delivery and cost—sometimes referred to as a project management triangle or "triple constraints." CM is compatible with all project delivery systems, including design-bid-build, design-build, CM At-Risk and Public Private Partnerships.
Construction biddingConstruction bidding is the process of submitting a proposal (tender) to undertake, or manage the undertaking of a construction project. The process starts with a cost estimate from blueprints and material take offs. The tender is treated as an offer to do the work for a certain amount of money (firm price), or a certain amount of profit (cost reimbursement or cost plus). The tender, which is submitted by the competing firms, is generally based on a bill of quantities, a bill of approximate quantities or other specifications which enable the tenders to attain higher levels of accuracy, the statement of work.
Cancer-related fatigueCancer-related fatigue is a symptom of fatigue that is experienced by nearly all cancer patients. Among patients receiving cancer treatment other than surgery, it is essentially universal. Fatigue is a normal and expected side effect of most forms of chemotherapy, radiation therapy, and biotherapy. On average, cancer-related fatigue is "more severe, more distressing, and less likely to be relieved by rest" than fatigue experienced by healthy people. It can range from mild to severe, and may be either temporary or a long-term effect.
SoudageLe soudage est un procédé d'assemblage permanent qui assure la continuité de la matière à assembler ; la soudure est le résultat obtenu (mais le terme est souvent utilisé pour le procédé). Cette continuité est ce qui distingue le soudage d'autres techniques d'assemblage mécaniques (rivetage, boulonnage, ...) ou par adhésion (collage), ainsi que les techniques de brasage L'opération peut être appliquée aux métaux ainsi qu'aux matières thermoplastiques (voir Soudage de plastiques) et au bois (voir Soudage du bois).
