Determinants of phosphorus mobilization during hemodialysis [PDF]
Our recent work proposed a pseudo one-compartment model for describing intradialysis and postdialysis rebound kinetics of phosphorus. In this model, phosphorus is removed directly from a central distribution volume with the rate of phosphorus mobilization from a second, very large compartment proportional to the phosphorus mobilization clearance. Here,

A novel electrochemical sensor for phosphorus determination in the high phosphorus liquid iron
A novel phosphorus sensor based on the bilayer structure of ZrO2(MgO)/CaAl1.64O3.46 was fabricated and tested in high phosphorus liquid iron in this work, where the 4CaO∙P2O5 used as the auxiliary electrode was synthesized in situ by the CaAl1.64O3.46 ...

Phosphorus Metabolism of Mycobacteria: Determination of Phosphorus Compounds in some Mycobacteria [PDF]
SUMMARY: A procedure is described for the determinati on of phospholipid, ‘phosphoprotein’, ‘acid-soluble’ phosphate, pentosenucleic acid (DNA), deoxypentose-nucleic acid (DNA), and ‘insoluble’ polyphosphate in samples of mycobacteria of about 30 mg. dry weight.

Phosphorus in Finnish soils in the 1900s with particular reference to the acid ammonium acetate soil test [PDF]
Comprehensive research into phosphorus (P) in soils and crops began in Finland in the early 1900s. The average amount of total P in the ploughed topsoil layer of mineral soils was about two tonnes per hectare in the 1930s, before the abundant use of ...

Quantitative determination of phosphorus in soybean lipids
Black and Hammond's method for determining lipid phosphorus has been modified for use with oils containing small amounts of phosphorus. The minimum amount of P that can be determined is 3 nmoles, with a coefficient of variation sd of 2%.
