Commercial availability of biological control agents.
2003The commercial use of biological control has seen a very fast development during the past 30 years. Currently, about 85 companies worldwide produce more than 125 species of natural enemies. The largest variety of commercially produced species of natural enemies is available in Europe, mainly as a result of a much larger greenhouse industry in Europe ...

Biological assay for zinc availability in wheat germ
Science of The Total Environment, 1983Our objective was to develop a method to determine the bioavailability of zinc in wheat germ. Weanling rats were fed for 10 days a Zn-free diet supplemented with different levels of Zn, with or without 2% wheat germ. Zinc concentrations of either tibia or femurs were plotted directly against Zn added to the diet, giving two lines that were essentially ...

Biological availability of endogenous calcitonin in rats
Bulletin of Experimental Biology and Medicine, 1998Significant correlation was established in 52-week-old rats between serum calcitonin content and density of sublemmal granules at the vascular pole of C-cells (N Vsg)∶r xy=0.922 ...

Assessment of the biologic availability of tetracycline products in man
Clinical Pharmacology & Therapeutics, 1972Significant differences were found in the absorption characteristics of three commercial tetracycline preparations. These differences were observed after both single‐dose and multiple‐dose administration. The relative amount of tetracycline absorbed (biological availability) but not the relative rate of absorption was greater for a standard preparation
