The thesis area consists of approximately thirty square miles in the Southern Cascades of Washington near Mount Adams. The oldest exposed rocks are sedimentary volcanic clastics and pyroclastic flows of late-Oligocene age that form a homocline in the northwest corner of the area. A thick pile of younger Tertiary lavas,...

La lagune de Nador se caractérise par un écosystème semi-fermé, en communication avec la mer par une étroite passe. Cet écosystème est sous l'influence de plusieurs facteurs externes tels que l'ensoleillement, l'apport en eau douce, les eaux de ruissellement, le lessivage des champs agricoles et les eaux usées urbaines. L'influence...
Le projet «système d’information géographique pour les pêcheries en Afrique de l’Ouest » a pour objectif de promouvoir l’utilisation des systèmes d’information géographique comme outil d’aide à la décision en matière d’aménagement des pêcheries. Un rappel préliminaire des critères caractérisant un produit d’aide à la décision (accessibilité technique, disponibilité en...
Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...
Uses for materials with a large surface area and high porosity have grown sig-nificantly in recent years. Porous materials have found usage in applications such as separation, gas storage, sensing, purification and more, prompting researchers to find and discover numerous new porous materials to suit a specific purpose. Hundreds of...
Two digestibility trials using sheep were conducted to determine
the digestibility coefficients of a commercially processed NaOH treated
annual ryegrass straw cube. Comparisons were made with loose, chopped
ryegrass straw and a ryegrass straw cube processed with molasses as a
binder.
The NaOH cubed straw was produced by spraying a...
A great deal of research has been focused on the microbiomes of terrestrial angiosperms (flowering plants), but much less research has been performed on the microbiomes of aquatic angiosperms (Turner et al. 2013). Eelgrass beds are extremely productive ecosystems that provide habitat for many marine organisms, such as fish, shellfish,...
Vibrio tubiashii is reported to be a bacterial pathogen of larval Eastern oysters (Crassostrea virginica) and Pacific oysters (Crassostrea
gigas) and has been associated with major hatchery crashes, causing shortages in seed oysters for commercial shellfish
producers. Another bacterium, Vibrio coralliilyticus, a well-known coral pathogen, has recently been shown to...
