The Chemical Compositions Of RR Lyrae Type C Variable Stars

We present a detailed chemical abundance study of eight RR Lyrae variable stars of subclass c (RRc). The target RRc stars chosen for study exhibit "Blazhko-effect" period and amplitude modulations to their pulsational cycles. Data for this study were gathered with the echelle spectrograph of the 100 inch du Pont telescope at Las Campanas Observatory. Spectra were obtained throughout each star's pulsation cycle. Atmospheric parameters-effective temperature, surface gravity, microturbulent velocity, and metallicity-were derived at multiple phase points. We found metallicities and element abundance ratios to be constant within observational uncertainties over the pulsational cycles of all stars. Moreover, the alpha-element and Fe-group abundance ratios with respect to iron are consistent with other horizontal-branch members (RRab, blue and red non-variables). Finally, we have used the [Fe/H] values of these eight RRc stars to anchor the metallicity estimates of a large-sample RRc snapshot spectroscopic study being conducted with the same telescope and instrument combination employed here.NSF AST-0908978, AST-1211585Baker Centennial Research EndowmentJohn W.

Porcs et volailles sous les tropiques

Le Centre Technique de Coopération Agricole et Rurale (CTA) a pour tâche essentielle de l’information scientifique et technique au profit des États d’Afrique, des et du Pacifique, signatairesde la Convention de Lome. Les principaux domaines concernés sont les suivants la production vegetale, l’élevage, I’agroforesterie, la pêche, l’aménagement rural ainsi que les aspects socio-économiques. Le Centre aussi bien les résultats de recherche que l’expérience acquise dans les projets de développement. Dans le but d‘aider les États ACP à améliorer leur potentiel de production animale, le a demandé au Dr. Preston de réaliser une qui fait l’objet de cette publication. Le abordé a une implication économique importante et il intéresse de nombreux pays. L‘auteur propose une alternative aux grands elevages intensifs et avicoles, peu adaptés aux paysACP et souventtrop coûteux en aliments importés. propose des solutions permettant d’améliorer l’élevage en utilisant les ressources locales. Moins de dépendance vis vis des importations et une meilleure valorisation des potentialités nationales, tel est le principe défendu dans cet ouvrage. est en avec les politiques définies par les États Daniel Mba Directeur du CT

Physician Involvement in Life-Ending Practices

This Article explains that we need to acknowledge physicians\u27 widespread involvement in ending patients\u27 lives by a variety of means, from withdrawal of life-sustaining treatment to euthanasia. Our inquiry should move from appearance and professional acceptance of practices to the conditions under which society allows physicians to be involved in ending patients\u27 lives

Salt Marsh Hydrology and Restoration

Hydrologic changes have affected coastal ecosystem sustainability along the Texas coast and throughout the Gulf of Mexico. Human utilization of coastal ecosystems has led to the alteration of tidal hydrology. These ecosystems are highly dynamic and are greatly affected by tidal fluctuations and restriction to hydrologic flow. The main objective of this study was to understand the hydrologic effects of tides, hydrologic alterations, and subsequent restoration on salt marshes along the Texas coast. The selected study site was Magnolia Beach marsh in Matagorda Bay, approximately 10.5 kilometers southeast of Port Lavaca, Texas. The study also had three more specific objectives. The first objective was to determine the cause of marsh loss observed since 1958. This was accomplished by a GIS analysis that identified over 62 hectares of marsh loss and a hydrologic analysis that identified a pair of tidal barriers. These barriers reduced the volume of water that could be exchanged between the salt marsh and Matagorda Bay. This intermittent connectivity resulted in the internal waters of the marsh becoming hypersaline. The second objective was to measure the hydrologic response to tidal reconnection with the removal of the two barriers. This was accomplished through the creation of a STELLA computer model, a numerical inlet hydrology model, and a meta-analysis to predict barrier removal success. An analysis of water level and water velocity before and after the barrier removal was used to quantify the success of the hydrologic reconnection. The final objective was to create a tide prediction model to better estimate wind driven tides. The current NOAA model has been effective to give astronomical tide movements, but is not capable of predicting wind driven tides. The Enhanced Tide Model resulted in a 13.34% average increase in tidal prediction accuracy across all NOAA tidal gauges in the Gulf of Mexico and the East coast of Florida. This tool could be used by the public, the shipping industry, and restoration planners to better understand tide dynamics in the Gulf of Mexico and abroad
