A reservoir is an integral component of a water resources system. Periodic evaluation of the sediment deposition pattern and assessment of available storage capacity of reservoirs is an important aspect of water resources management. The conventional techniques of quantification of sediment deposition in a reservoir, such as hydrographie surveys and the inflow-outflow methods, are cumbersome, c...

abstract one of the most important sources of drinking and agricultural water needs is rivers. one of the oldest methods of getting water from rivers that still has the greatest use is the gravity intake. in this type of intake, due to the disproportionate velocity at the upstream and downstream mouth of intake, occur flow separation and following sedimentation at the upstream mouth. in this st...

Activity of glucocorticoid receptor in mouse mammary cytosol changes during lactogenesis. The highest receptor activity is observed in the second half of pregnancy. The receptor from mammary glands from lactating and pregnant mice exhibits the same sedimentation pattern, as well as the same specificity and affinity for binding of steroid hormones.

In a case of neuroblastoma the presence of an abnormal blood constituent was suspected from the raised erythrocyte sedimentation rate, sludging of the red cells, marked rouleaux formation, an atypical Leishman stain, increased plasma viscosity, and a distorted protein electrophoresis pattern. The abnormal constituent was shown to be a mucopolysaccharide which was either hyaluronic acid or chond...

Sedimentation dynamics in the East China Sea was investigated based on profiles and inventories of Pb , Cs and ex Pu in sediment cores collected from various settings in this marginal sea. The derived sedimentation rates vary by two orders of magnitude, from ;2 to 0.02 cm yr, and generally decrease southward along the inner shelf and eastward offshore. This pattern is consistent with the disper...

Studies were carried out to determine whether or not oxygenated derivatives of cholesterol (e.g., 25-hydroxycholesterol) that specifically suppress the activity of 3-hydroxy-3-methylglutaryl-CoA reductase [mevalonate:NADP(+) oxidoreductase (CoA-acylating), EC 1.1.1.34], bind to a soluble component of the cytoplasm different from that which binds the nonsuppressor, cholesterol. Density gradient ...

A method has been developed for combining lipids in vitro with delipidized high density lipoprotein (apo-HDL) by mixing a concentrated petroleum ether solution of lipids with an aqueous solution of apo-HDL. When a mixture of plasma lipids was used, combination of phospholipids and cholesterol was observed in amounts comparable with those present in native HDL; triglycerides and cholesterol este...
