Student project
Abstract

L’objectif de ce projet est de réaliser l’examen d’un ouvrage d’art et de proposer un projet d’intervention. L’examen permet de vérifier la sécurité structurale et l’aptitude au service de la structure porteuse. Une prévision de l’évolution de l’état de la structure est alors dressée et la durée d’utilisation ultérieure estimée. Selon les résultats obtenus des solutions d’interventions seront proposées.¨ Dans la deuxième partie du 20ème siècle, de nombreux ouvrages d’arts en béton armé précontraint ont vu le jour tel que le Pont de Sierne à Genève. L’examen a permis de conclure que cet ouvrage est en très bon état et par conséquent ne nécessite aucun renforcement particulier dans les conditions d’utilisation actuelles. En effet, la capacité portante des différents éléments s’est révélée suffisante. Cependant l’utilisation du pont a changé et un élargissement du tablier est considéré pour accueillir une voie de circulation et une piste cyclable supplémentaire. Ce projet de master propose une intervention permettant d’atteindre l’objectif d’élargissement tout en conservant l’intégrité esthétique de l’ouvrage existant. La solution retenue se compose d’un porte-à-faux en CFUP soutenu par des béquilles acier. L’ensemble est préfabriqué et permet un montage minimisant la durée d’interruption du trafic. De plus, la technologie du CFUP

Evolution
In biology, evolution is the change in heritable characteristics of biological populations over successive generations. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation.
Evolution and the Catholic Church
The Catholic Church holds no official position on the theory of creation or evolution, leaving the specifics of either theistic evolution or literal creationism to the individual within certain parameters established by the Church. According to the Catechism of the Catholic Church, any believer may accept either literal or special creation within the period of an actual six-day, twenty-four-hour period, or they may accept the belief that the earth evolved over time under the guidance of God.
Molecular evolution
Molecular evolution is the process of change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, the evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes.

Sexual conflict drives male manipulation of female postmating responses in Drosophila melanogaster

Laurent Keller, Brian Dennis Hollis

In many animals, females respond to mating with changes in physiology and behavior that are triggered by molecules transferred by males during mating. In Drosophila melanogaster, proteins in the seminal fluid are responsible for important female postmating ...
