Nature and Thermal Behavior of Precipitated Calcium-Magnesium Phosphates

1. A large number of invertebrates have cells that produce intracellular granules of amorphous calcium magnesium phosphates that are thought to act as ion stores or sites of metal detoxification. 2. The interatomic potentials and force constants have been calculated for these ions, and computer simulations of the crystal lattices have been used to determine the effects of ion substitutions on these lattice energies. 3. The results provide insights into the mechanisms of granule formation and the effects of ion substitutions on cell physiology.

SUMMARYGrowing wether sheep in metabolism cages were fed a low phosphorus diet (0·75g P/day) supplemented with 1·75 g P/day as either a magnesium phosphate (20·0% Mg, 18·5% P) or a calcium magnesium phosphate (16·1% Ca, 6·0% Mg, 18·5% P). In addition, the magnesium phosphate provided 1·87 g Mg/day and the calcium magnesium phosphate 0·57 g Mg/day. In each case comparisons were made with equivalent amounts of phosphorus and magnesium supplied as dicalcium phosphate (26·5% Ca, 16·0% P) and magnesium oxide (60·0% Mg).All the supplements resulted in similar positive phosphorus retentions of between 0·77and 0·92 g P/day compared with a daily loss of 0·17 g P/day for the low phosphorus diet. Calcium retentions were higher (1·40 and 1·70 g Ca/day) whendicalcium phosphate rather than the magnesium phosphates (1·16 g Ca/day) were given. Magnesium retentions were increased from 0·1 g Mg/day (unsupplemented) to 0·3–0·4 gMg/day and were similar for both magnesium oxide and the magnesium phosphates.Blood phosphorus and magnesium concentrations were increased to a similar degree by all forms of supplementation.

Abstract: Different Physico-chemical parameters of Kanekal tank water, Kanekal were estimated from October 2012 to September 2014 to assess its quality. The different parameters like Temperature, pH, TDS, conductivity, salinity, dissolved oxygen, turbidity, alkalinity, free carbon dioxide, chloride, total hardness, calcium, magnesium, phosphates, sulphates, silicates, nitrites, nitrates, BOD and COD were carried out by standard methods. These parameters showed either positive or negative correlation between each other. The analysis revels these parameters are interrelated with each other. From the data it can be said that water of this tank is partially contaminated with human faeces, domestic sewage etc. Hence it is not good quality for culture of fish as well as drinking for animals.KeywordsÂ â€“Kanekal Tank, water quality, Physico-chemical parameters, BOD, COD
