effect of calcium carbonate and calcium sulfate on e.coli survival in fine sand mixtures

the effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...

transport of pseudomonas fluorescents through unsaturated sand columns: influence of calcium carbonate and calcium sulfate

transport of pathogenic bacteria has been recently considered a major source surface and subsurface water contaminations. soil could affect transport or filtering of bacteria depending on its physical and chemical properties. calcium carbonate and calcium sulfate are two important minerals of arid and semi-arid soils that their effect on bacteria transport has not been investigated, yet. in thi...

Calcium Carbonate and Calcium Sulfate in Martian Heteorite Eeta79001

Availability of calcium from skim milk, calcium sulfate and calcium carbonate for bone mineralization in pigs.

Dairy products provide abundant, accessible calcium for humans, while some calcium sulfate-rich mineral waters could provide appreciable amounts of calcium. But there is little evidence that this calcium is as available as milk calcium for making bone. The availability of calcium was studied by monitoring bone parameters in 2-month-old pigs fed restricted amounts of calcium (70% RDA) for 2.5 mo...

Effect of Calcium Carbonate Fineness on Calcium Sulfoaluminate-Belite Cement

This study investigated the hydration characteristics and strength development of calcium sulfoaluminate-belite (CSAB) cements incorporating calcium carbonate (CC) powders with various particle size distributions and different gypsum amounts. In general, the CSAB hydration was accelerated by the CC powder, but the acceleration and resulting strength improvement were more effective with finer CC...
