For algae-dolostone of tidal flat and lagoon facies. δ=0.922-1. MgCO=50.230-50.912%. Sr/Ba=0.277-0.313, also less than 1. Dolomite is developed on the Coorong dolomitizationmodel, but with fresh water effect.
For fresh,salt,saturated salt,and mixed salts clay base muds treated by 2.0% of IE,the API fitrate losses are of 12.2,14.3,19.5,and 14.0 mL in intact state and of 13.8,19.2,28.0,and 16.3% after rolling at 150℃ in 16 hrs.
Oxygen isotope of carbonate vein is lighter with narrow ranges,whose value varies from -10.66‰ to-18.91‰,and its Z value most is 100 and 110.Those indicate there was fresh-water leaching during formation of carbonate vein.
Effect of Toxic Industrial Pollutants on the Activity and Isoforms of Acid DNase in the Freshwater Snail Viviparus viviparusL.
A preparation of lysozyme from a freshwater bivalve, Unio pictorum, has been isolated by sorption to chitin, and its physicochemical properties have been studied.
Respiration Rate and Species-Specific Lifespan in Freshwater Bivalves of Margaritiferidae and Unionidae Families
We studied changes in the respiration rate in five species of freshwater bivalves as a function of animal age and size.
The longest and shortest lifespan among the studied mollusks was specific for the pearl mussel Margaritifera margaritifera(Ru= 37 kJ and T20= 36 years) and the freshwater mussel Anodonta anatina(Ru= 8 kJ and T20= 8 years), respectively.
Shape of the fresh-water lens resulting from canal seepage
Sulfur Compounds in Bottom Sediments of Fresh-Water Basins (Mouth of the Severnaya Dvina River and Rybinsk Water Reservoir)
Contents and correlations of some trace elements (Sr, Li, F, Ba, and others) indicate that primary sediments formed under humid-semihumid paleoclimate in a fresh-water paleobasin (lagoon) characterized by occasional increase in salinity.
The operation conditions of the inner surface of the long-distance Astrakhan-Mangyshlak fresh-water main and the properties of corrosion deposits on it are considered.
In ornamental carps from the collection of the Experimental Station, All-Russia Research Institute of Fresh-Water Fisheries, fish with a dirty dark tint of body color among orange and white fish were found.
