A large (540 square meters) bed of Bathymodiolus n. sp. (Mytilidae: Bivalvia) rings a pool of hypersaline (121.35 practical salinity units) brine at a water depth of 650 meters on the continental slope south of Louisiana. The anoxic brine (dissolved oxygen =0.17 milliliters per liter) contains high concentrations of methane, which nourishes methanotrophic symbionts in the mussels. The brine, which originates from a salt-cored diapir that penetrates to within 500 meters ofthe sea floor, fills a depression that was evidently excavated by escaping gas. The spatial continuity of the mussel bed indicates that the brine level has remained fairly constant; however, demographic differences between the inner and outer parts of the bed record small fluctuations. 相似文献

Every equine hoof has a certain amount of distortion. This presents in various forms: flares, dished toes, under-run heels, and cracks. Several farrier texts anecdotally suggest a correlation between hoof capsule distortion and lameness. The goal of this study was to evaluate the effects of the Sigafoos Series I glue-on shoe on hoof capsule distortion, and specifically, the effect on dorsal wall deviation. Measurements of the hoof were made using the Metron hoof evaluating system by Eponatech. Comparisons were made of the following values: dorsal length, hoof angle, dorsal wall deviation, hairline angle, hairline deviation, heel/toe height, heel height, heel angle, and support length. The study group consisted of front feet of horses shod exclusively in the Sigafoos glue-on shoe for a period of 1 year, and the control group consisted of 133 front feet from horses using nailed on shoes for a similar period and with a musculoskeletal complaint. The results indicate a 48% reduction in dorsal wall deviation for the study group. This finding supports the use of this glue-on shoe as beneficial with the goal to reduce capsular distortion of the dorsal wall. 相似文献

Multiple drug therapy is often used in veterinary practice; occasionally, inappropriate combinations of drugs may be administered which interact to produce adverse responses. Such interactions may occur in vitro because of physically or chemically incompatible drugs having been mixed before administration or in vivo. A number of important in vitro incompatibilities concerning parenteral drugs are tabulated, consideration having been given both to problems attending the use of intravenous fluids as vehicles for their administration and to incompatibilities between the drugs themselves. Interactions which occur in vivo are also examined; these have been grouped according to the various mechanisms by which they occur. 相似文献

Abstract: On many measures of ethno‐linguistic diversity, Papua New Guinea is the most fragmented society in the world. I argue that the macro‐level political effect of this diversity has been to reduce, rather than increase, the impact of ethnic conflict on the state. Outside the Bougainville conflict, and (to a lesser extent) the recent upsurge of violence in the Southern Highlands, ethnic conflicts in Papua New Guinea have not presented a threat to national government. In contrast to most other ethnically diverse societies, the most consequential impacts of ethnic conflict in Papua New Guinea are at the local level. This paper therefore examines the disparate impacts of local‐ and national‐level forms of ethnic conflict in Papua New Guinea. 相似文献
