General Balance

In the general balance of water consumption, a considerable part falls on softened water. The processes of obtaining softened water form a significant amount of liquid waste containing calcium and magnesium salts. We show the possibility of using wastewater from water softening installations for the treatment of wastewater containing dyes. The obtained results demonstrate high efficiency of wastewater treatment in textile factories. An additional advantage of the use of sewage water softening plants is the economy of reagents for the removal of dyes.

Blood Platelet Aggregation

SummaryThe effect of calcium and magnesium on the aggregation of rabbit blood platelets in vitro was studied, with the following results:1. Platelet aggregation induced by ADP or collagen could be prevented by EGTA or EDTA. The aggregating effect was restored by recalcification. The effect was also restored by addition of magnesium in EDTA-PRP, but not in EGTA-PRP unless a surplus of calcium was present.2. Calcium remained in concentrations of the order of 0.15–0.25 mM after dialysis or cation exchange of plasma. Aggregation of washed platelets resuspended in such plasma could not be produced with ADP or collagen, unless the calcium concentration was increased or that magnesium was added.3. The adhesiveness of blood platelets to collagen was reduced in EGTA-PRP and EDTA-PRP. Release of ADP from platelets influenced by collagen could not be demonstrated either in EGTA-PRP (presence of magnesium) or in EDTA-PRP.4. It is concluded that calcium is a necessary factor both for the reaction leading to release of ADP and for the the aggregation produced by ADP.5. Thrombin induced aggregation of washed platelets suspended in tris-buffered saline in the presence of calcium. No effect of magnesium could be observed unless small quantities of calcium were present.

A thermochemical study of natural calcium and magnesium orthosilicate ─ monticellite (Ca1.00Mg0.95)[SiO4] (Khabarovsk Territory, Russia) was carried out on the Tian-Calvet microcalorimeter. The enthalpy of formation from the elements fHоel(298.15 K) = -2238.4 4.5 kJ / mol was determined by the method of high-temperature melt solution calorimetry. The enthalpy and Gibbs energy of formation of monticellite of the theoretical composition of CaMg[SiO4] are calculated: fH0el(298.15 K) = -2248.4 4.5 kJ/mol and fG0el(298.15 K) = -2130.5 4.5 kJ/mol.

The present study was carried out to evaluate the variations in serum minerals ( viz. calcium, magnesium and phosphorus) and transaminases in ketotic buffaloes. Results of blood analysis revealed a significant (P<0.05) reduction in serum phosphorus in ketotic buffaloes whereas nonsignificant (P>0.05) difference occur in serum calcium and magnesium in ketotic buffaloes as compared to control. At the same time significant increase in transaminases GPT, GOT and GGT have been observed .
