Tables for simplifying calculations of activities produced by thermal neutrons
F. E. Senftle, W.R. Champion
1954, Il Nuovo Cimento (12) 550-571
The method of calculation described is useful for the types of work of which examples are given. It is also useful in making rapid comparison of the activities that might be expected from several different elements. For instance, suppose it is desired to know which of the three elements, cobalt,...
Rodent repellents, preparation and properties of thiouronium compounds and cyclic imides
E. Bellack, J.B. DeWitt
1954, Journal of Agricultural and Food Chemistry (2) 1176-1179
Syntheses and bioassays of cyclic imides and thiouronium compounds were carried out as part of a search for materials capable of preventing rodent damage to packaged commodities. Previous studies had shown that repellent activity was associated with functional groups containing nitrogen and sulfur, and was enhanced by the presence...
A comparative study of 28 culture media for Trichomonas gallinae
L. S. Diamond
1954, Experimental Parasitology (3) 251-258
1. 1. A study was made of the ability of 28 different culture media to support growth of 5 strains of Trichomonas gallinae with their normally associated bacteria. A standard inoculum of 50 protozoa was used, and the cultures were incubated at 35 ?C. Based upon the number of positive...
