Evaluation of phosphate knowledge and the effectiveness of a phosphate management protocol to achieve optimum serum phosphate levels in haemodialysis patients
… to achieve and maintain acceptable serum phosphate levels, current prevalence rates of hyperphosphataemia and associated health risks, in haemodialysis patients indicate that controlling serum phosphate levels remains a challenge in the 21st century. The aims of this study were to evaluate …

Studies on the metabolism of polyhydroxyalkanoic acid and phosphate in the biological excess phosphate removal process
… of my thesis were to examine the role of PHA in phosphate sequestering sludge metabolism and to test the effect of nutrient combinations on the intracellular level of PHA. The role of PHA in the process was studied by measuring levels of PHA in both functional and non-functional sewage treatment …

Formylated dipyrromethane based phosphate derivatives receptors
… chemistry is provided with a particular focus on phosphate anion recognition. The common defining feature of the receptors reviewed is the pyrrole ring. The new structures are often designed via modification of known macrocyclic molecules. In Chapter 2, structural modifications of a Schiff-base …

INTRACELLULAR TARGETS OF SPHINGOSINE-1-PHOSPHATE
The bioactive lipid mediator sphingosine-1-phosphate (S1P) has emerged as a key regulator of a variety of important physiological functions, including cell growth, cell survival, cell motility, angiogenesis, lymphocyte trafficking, and mast cell function. S1P is formed by two different sphingosine …

Reduction of Fluorine in Phosphate Rock
Phosphorus is widely distributed in the earth's crust, constituting about 0.13%. Like many other reactive elements, it is never found free in nature. Phosphorus is an essential constituent of both vegetable and animal matter; thus, it is important as a component of fertilizers and feed supplements.

Field study with rock phosphate and superphosphate 1952 to 1990 and dissolution of rock phosphate in silage leachate
… agronomic and economic effectiveness of rock phosphate (RP) was compared with super phosphate (SP) on crops consisting of oats-alfalfa (hay)-corn-corn (rotation ""A"") and corn-soybean (rotation ""B""). Phosphorus applications ranged from 0 to 80 pounds P$\sb2$O$\sb5$/a. Agronomically, …
