Lors de son jaunissement, une feuille subit aussi bien des modifications morphologiques que métaboliques. Ce processus est appelé « sénescence ». Une meilleure compréhension des mécanismes de la sénescence représente un challenge très important non seulement pour la recherche fondamentale mais aussi pour de futures applications en biotechnologie. La thèse présentée ici porte sur d’importants aspects relatifs aux mécanismes cellulaires et métaboliques rencontrés lors de la sénescence foliaire et ce, en apportant une attention particulière à l’implication des mitochondries lors de ce processus.

Supramolecular chemistry involves the study of noncovalent interactions that take place between molecules. A supramolecule or host-guest complex is formed when a noncovalent binding or complexation event occurs between two such molecules. Hydrogen bonds, electrostatics, pi-stacking, hydrophobic effects, solvatophobic effects and van der Waals forces are all types of noncovalent interactions. Biological systems have provided much of the inspiration for the development of supramolecular chemistry, and many synthetic supramolecular systems have been designed to mimic biological and enzymatic proc

Abstract:
Iron is ubiquitous in the environment, ranking fourth in abundance in the earth's crust. Iron is responsible for many environmental mechanisms including the distribution of plant nutrients and pollutants. Iron can exist in several minerals, including iron oxides. Arsenic is a naturally occurring metalloid which has been confirmed by the EPA as a carcinogen. Recently, an arsenic epidemic has unfurled in Bangladesh, poisoning an estimated 70 million people. Arsenic contamination does not exist only in the third world, but also in the United States, including Iowa. Due to the widespread distribut

Abstract:
As wind energy penetration levels increase, there is a growing interest in using storage devices to aid in managing the fluctuations in wind turbine output power. Vanadium-Redox batteries (VRB) and Lithium-Ion (Li-Ion) batteries are two emerging technologies which can provide power smoothing in wind energy systems. However, there is an apparent gap when it comes to the data available regarding the design, integration and operation of these batteries in wind systems. This thesis presents suitable battery electrical models which will be used to assess system performance in wind energy applicatio

Abstract:
The chemistry of transition metal clusters has been a fast developing area of organometallic research in recent years. Compared to mononuclear metal complexes, polynuclear clusters offer more opportunities to study cooperative effects and electron reservoir properties between contiguous metal centers, in addition to functioning as storehouses for the release of catalytically active small fragments capable of exhibiting heterosite subtrate activation. Theoretically, metal clusters are intermediates between mononuclear complexes and metal surfaces, i.e., they serve as a bridge between molecular

Abstract:
The utility of fluorophores for sensing applications in the current state of the art of biological imaging hardly needs to be stated. The use of fluorophores in exploring and determining the internal structure and active dynamics of cellular processes has been pivotal, allowing us to explore areas of study inaccessible through other means. A simple search of fluorophores in Scifinder© demonstrates their popularity, as the number of hits increases year after year, until the year of 2015 when there were 1400+ journal articles published with the phrase. Fluorophore applications range far and wid

Abstract:
Lactococcus lactis a été étudié jusqu'à présent pour ses capacités de fermentation. Notre équipe a mis en évidence qu'en présence d'hème et d'oxygène, L. Lactis est capable de respirer. La croissance par respiration s'accompagne d'une augmentation de la biomasse, d'une baisse de la production de lactate et d'une amélioration de la survie à long terme. Une étude par électrophorèse bidimensionnelle (E2D) menée sur des cultures en phase exponentielle montre que la plupart des protéines cytoplasmiques présentes en respiration le sont déjà en fermentation. Une seule protéine spécifique de la respir
