The cancer chemotherapy laboratory has been active since 1952. It now functions as an integrated unit with joint services and collaboration of a chemical synthesis division under Dr. Kloetzel and pharmacological supervi sion under Dr. Thienes. The progress of the laboratory is greatly facilitated by the close collaboration and support obtained from a number of drug and pharmaceutical houses, es...

to evaluate the relationships between soil inorganic phosphorus p (pi) fractions, the soil p test and plant parameters such as plant p uptake, dry matter yield, tissue p concentra-tion and relative yield, glasshouse experiments and chemical analyses were conducted on 13 calcareous soils from six agricultural and seven adjacent bushland (virgin soil) sites. four rates of p (0, 15, 30, 60 mg/kg s...

Formulas proposed for the mineral of bone were reviewed. Literature data were collected where Ca, P, Na, Mg and CO3 are determined in the same samples. These data were analyzed for their conformity to the above mentioned formulas. According to this analysis Mg is contained in a phase having the Ca/P of magnesium whitlockite within the limites of error. Na is contained in a carbonated calcium ph...

A better understanding of the P dynamic resupply roles fertilization from soil solids to solution is urgently required optimize sustainable fertilizer management practices for efficient supply. five–year experiment was used investigate effects on fractions and availability, kinetic based a novel simulation technique (Diffusive gradients in thin films (DGT) DGT–induced fluxes sediments soils (DI...

43Ca nuclear magnetic resonance (NMR) spectroscopy has been extensively applied to the detailed study of octacalcium phosphate (OCP), Ca8(HPO4)2(PO4)4.5H2O, and hybrid derivatives involving intercalated metabolic acids (viz., citrate, succinate, formate, adipate). Such phases are importance in development a better understanding bone structure. High-resolution magic angle spinning (MAS) experime...
