Application Of Oscillographic Polarography To Determination Of Organic Phosphorus Pesticide Residues, Raymond J. Gajan
Application Of Oscillographic Polarography To Determination Of Organic Phosphorus Pesticide Residues, Raymond J. Gajan
Food and Drug Administration Papers
Some organic phosphorus pesticides have been determined successfully by polarography (1-7). However, in most cases the methods were used to determine the pesticide in commercial formulations. Little has been reported on the polarographic determination of microgram amounts of these pesticides such as those encountered in pesticide residue analysis.
Many of the methods used for the determination of these pesticides are nonspecific. They are based on cholinesterase assay (8- 12), radioactive tracer analysis (13, 14), total phosphorus (15-17), and paper chromatography (18-24).
In this paper we will discuss the polarography of Systox, Di-Syston, and· Thimet and some of their oxidation products, …

Swine Brucellosis And Human Health, Us Public Health Service
Food and Drug Administration Papers
Swine brucellosis is caused by Brucella suis, a strain of bacteria which also cau ses human brucellosis, or undulant fever. T his disease is an imp 0 r tan t public health problem which affects thousands of farmers, livestock handlers, meat processors, and butchers .. The U. S. Department of Agriculture estimates that 6.15 percent of the 1.8 million swine herds in the Nation are infected with brucellosis. This represents about 131,000 in f e c ted herds on farms, where some 579,000 farm people come into daily c ontact with these herds. The infection rate among these rural persons …
Purification And Sanitary Control Of Water (Potable And Waste), Paul W. Kabler
Purification And Sanitary Control Of Water (Potable And Waste), Paul W. Kabler
Public Health Resources
Although most of the streams draining inhabited regions are contaminated with human or animal feces, water-borne disease today in the United States is relatively uncommon. Pathogenic enteric microorganisms probably do not multiply in raw water sources under normal conditions. They usually disappear in a relatively short time, with the rates depending on variations in environmental conditions. Urban water supplies have played a diminishing role in the transmission of intestinal disease because of improvements in the detection and enumeration of pollution indicators, water and sewage treatment processes, and t h e sanitary control of water systems.

Nebraska Beef Cattle Reports
Feeding pastured calves protein supplements weekly instead of daily during the winter made little difference in either winter or summer gains, according to research results to date.
Two sources of protein were used in the trial. (I) Second cutting alfalfa hay was fed at the rate of four pounds per head daily. One group of calves was fed four pounds per head daily and one group was fed 28 pounds per head once each week. (2) Forty percent protein, pellets or cake, was fed at the rate of one pound per head daily. One group was fed one pound per …
