Soil thermal conductivity is significantly influenced by saturation and dry density. In this paper, a family of empirical correlations are presented which relate soil thermal conductivity to saturation for five soil types, namely, gravel, sand, silt, clay and peat, in both the frozen and unfrozen states. These correlations were developed from a soil thermal conductivity database which was const...

background: estrogens include estoril (e3), estradiol and estrone (e1). these chemicals are produced in human and animal bodies as well as in synthetic chemicals (drugs). estrogens can enter water sources in different ways. when these chemicals enter the human body through water and wastewater, they have the ability to mimic or disrupt the normal estrogen activities in humans and animals. estro...

Many landfill siting reports, of which those of the Franklin County, OH, landfill are typical, imply continuity of minor sand bodies in till between widely-spaced test holes where sand deposits fall within similar depth ranges. This review of studies of the local origin of most sand and gravel "lenses" or "seams," and their transport in active glaciers, however, indicate that most such deposits...

in this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from sm to gm on behavior of sandy soil. in this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 kpa were carried out in ...

of the Thesis Evaluation of Ar-Ar ages of Individual Mica Grains for Provenance Studies of Loess, Long Island, NY by Jian Zhong Master of Science in Geosciences State University of New York at Stony Brook 2001 Loess in a one-meter thick section on the SUNY Stony Brook Campus has been studied for grain size distribution and provenance. The loess provenance has been evaluated using single crystal...

Colic (abdominal pain), caused from the accumulation of sand and small pieces of gravel in the large colon, continues to be a problem for horses. In one study, of the cases of colic with an identifiable cause, 5% of the reported colic cases were due to sand. This was greater than those caused by gas (3%), mesenteric arteritis caused by small strongyles (1%), and ingestion of moldy grain (1%). I...

Studies on predat~on are often based solely on the measurement of predator consumption rates, providing little information on underlying behavioral mechan~sms. In this study, behav~oral observations were used In conjunchon with consumption rate analyses to investigate the predatory interactions between 2 brachyuran crabs, Ovalipes ocellatus and Calllnectes sapidus, and juvenile hard clams Aderc...
