The aim of this study was to investigate relationships between soil properties and plant species to determine the most effective factors separating vegetation communities in Rineh rangeland. Three stratifying variables were selected including slop, aspect and elevation. The study area was partitioned by combining these classes to generate homogenous units. 1m2 quadrates were located at sampling...
Relatively little information is available on the phosphorus content of horse blood. Abderhalden (1)) in his pioneer investigations of 1898, analyzed the blood of two horses and reported 3.3 mg. of inorganic phosphorus per 100 ml. of serum. Robinson (2), using the method of Fiske and Subbarow, determined the inorganic phosphorus content of the blood of forty-four horses and found a range of 1.9...
There are two biological systems available for removing phosphorus from waste water, conventional phosphorus removal (CPR) and denitrifying phosphorus removal (DPR) systems, and each is characterized by the type of sludge used in the process. In this study, we compared the characteristics associated with the efficiency of carbon utilization between CPR and DPR sludge using acetate as a carbon s...
