This paper introduces the application of IP multicasting for enhancing of software-only DSM systems and, at the same time, sim-pliication of the programming model by ooering a simple memory consistency model. The described algorithm is the foundation of a runtime system implemented as lesystems for the Windows NT and FreeBSD operating systems. 1 Introduction Software distributed shared memory (...

Riverine ecosystems are linked to their watersheds, and both land use and physiographic environmental conditions influence nutrient dynamics and water quality. We assessed aquatic nutrients and their relationship with land use and physiographic conditions at multiple spatial scales in the Brazos River watershed (Texas, USA) to examine the interactions between land use and physiography and their...

Migratory fishes with periodic life history strategies are sensitive to river regulation. Populations of these may persist in highly regulated rivers by using tributaries that provide access intermittently connected spawning and early stage habitat floodplains. We analyzed system hydrology associated movement a long-lived strategist, the alligator gar ( Atractosteus spatula), Brazos River, Texa...

Drainage systems of the Great Plains and western Gulf Slope underwent substantial changes through diversions and stream captures during the Pleistocene, either as the result of the glacial advances or through independent geologic processes. The distributions of a variety of fishes that range across west-central North America, such as the plains killifish (Fundulus zebrinus), are thought to be t...

Accretionary carbonate spherules of small size are a common component of distal Chicxulub impact ejecta deposits and are documented at Brazos River, Texas, and Bass River, New Jersey, located about 1000 km and 2500 km respectively from the crater. This spherule type is also present in northeast Mexico and is related to accretionary carbonate lapilli present in proximal Chicxulub ejecta deposits...

We report on new collections of cephalopods (ammonites and nautilids) from the Cretaceous-Paleogene (K-Pg) successions Corsicana Kincaid formations exposed along Brazos River in Falls County, Texas. An abundant fauna eight species comprising four genera ammonites is described Formation, including Discoscaphites mullinaxorum n. sp. The presence aptychi (probably lower jaws) Eubaculites, as well ...

The effects of heterogeneous reactions between river-borne particles and the carbonate system were studied in plumes Mississippi Brazos rivers. Measurements within these revealed significant removal dissolved inorganic carbon (DIC) total alkalinity (TA). After accounting for all known DIC TA sinks sources, (i.e., CaCO3 precipitation cation exchange adsorbed ions) found to be responsible a fract...
