It is well known that the administration of acids or of potentially acid salts, such as ammonium chloride, to animals often leads to decalcification. Apparently several factors are involved, such as the age of the animal, the calcium intake, and the disturbance in the acid-base equilibrium. Burns (1) fed hydrochloric acid to rabbits and rats and found that it retarded growth, increased the wate...

Theoretical calculations and preliminary measurements of vibrational Raman optical activity (ROA) spectra of different species of amphetamine (amphetamine and amphetamine-H) are reported for the first time. The quantum chemical calculations were carried out as hybrid ab initio DFT-molecular orbital calculations by use of the Gaussian 03W program, based on complete geometry minimizations of the ...

“Food additives” is a general term referring to anything added to food to achieve specific functions, for example, to aid in food processing, to increase the product’s nutritive value, to enhance the product’s palatability through regulating its physicochemical properties, and to extend the product’s storage stability. In muscle food processing, both synthetic and natural, generally recognized ...

Pirie, van Heyningen & Flanders (1955) showed that the concentrations of certain acid-soluble phosphates in the lens, when estimated by the enzymic method of Slater (1953), were much lower than the concentrations reported by Nordmann & Mandel (1952), who used the barium-fractionation method of LePage (1948, 1949). This method has, until recently, been the accepted and standard one for estimatio...

The plasmodium of Physarum polycephalum reacts to various kinds of chemicals substances and moves towards or away from them. Threshold concentration of recognition of chemicals was examined in terms of membrane potential and of the averaged motive force of tactic movement by using a double-chamber method, i.e., a single plasmodium was placed between two compartments through a narrow ditch, and ...

conclusions in critically ill patients, the symptoms of hypophosphatemia may not be apparent, but clinicians should be vigilant about this complication during therapy. in cases of severe symptoms (e.g., cardiopulmonary distress, anemia and thrombocytopenia, or rhabdomyolysis), phosphate therapy under close surveillance is warranted. introduction although asymptomatic hypophosphatemia is a commo...

Step 2 Phosphating The metal is treated with phosphoric acid, leading to the following two reactions occuring in the zinc-rich surface of the steel: 2H3PO4 + 3Zn → 3H2 + Zn3(PO4)2 2H3PO4 + Fe + 2Zn → 3H2 + FeZn2(PO4)2 This gives a mixture of zinc phosphates. The electrocoat paint binds better to these zinc phosphates than to the steel alone, and the zinc phosphates corrode much slower than the ...
