1. Rachitic bone lesions may be produced in rats by a diet containing an excess of calcium, but deficient in phosphates. 2. Similar lesions follow a diet deficient in calcium, but containing an excess of phosphates. The endochondral lesions, however, are less pronounced. 3. A diet deficient in both calcium and phosphate induces atypical rickets. 4. Inorganic salts other than calcium or phosphat...
The article presents the distribution coefficient (Kd) values of 137Cs and 90Sr tracer radionuclides in solutions sodium calcium salts for a wide range commercially available inorganic sorbents: natural synthetic aluminosilicates, manganese, titanium zirconium oxyhydrates, phosphates, titanosilicates alkali metals, ferrocyanides transition metals. results were obtained using standard technique ...

The current study was conducted on 10 wells of water located within the city Mosul / left side. quality this evaluated to determine number physical and chemical properties, including acidity, turbidity, total dissolved salts, alkalinity, nitrates, chlorides, phosphates, calcium, magnesium, sulfates. showed that values of solids sulfate rates for well ranged between 155-1150 mg/L, 226-1037mg/L...
The algorithm is suggested for selecting most appropriate and sensitive bioassay method to a particular type of pollution prevailing in the study area. bases on battery bioassays, which necessarily includes mortality test Daphnia magna Straus, 1820. Other approaches comparing sensitivity methods are selected aim. has been tested model situ samples. According proposed algorithm, tests D. Cerioda...
The efficiencies of the restoration two lakes varied morphometries and trophic states—meromictic, hypertrophic Lake Klasztorne Ma?e, dimictic, eutrophic Du?e—with use phosphorus inactivation method with sequential application iron aluminum compounds have been compared. total dose agents applied for Ma?e was 38 tons PAX 18 (aluminum polychloride) 14 PIX 111 (iron chloride), Du?e, it 74 46 111.

Calcium phosphate bions (CPB) are biomimetic mineralo-organic nanoparticles which represent a physiological mechanism regulating the function, transport and disposal of calcium and phosphorus in the human body. We hypothesised that CPB may be pathogenic entities and even a cause of cardiovascular calcification. Here we revealed that CPB isolated from calcified atherosclerotic plaques and artifi...
In this study, the process of anthropic decay on stone materials and on the lithobiontic microbial colonization associated was investigated by means of both laboratory simulation (granite) and field experiments (dolostone ́s historical quarry), all of them stone materials traditionally used in heritage construction. A wide variety of salts including sulphates, phosphates and chlorides resulted f...
Several reports have mentioned the existence of non-apatitic environments of phosphate and carbonate ions in synthetic and biological poorly crystalline apatites. However there were no direct spectroscopic evidences for the existence of non-apatitic environment of calcium ions. Xray Absorption Spectroscopy, at the K-edge of calcium, allows the discrimination between different calcium phosphates...
