Pyrethroids are the active ingredients in most insecticides available to consumers for residential use in the United States. Yet despite their dominance in the marketplace, there has been no attempt to analyze for most of these compounds in watercour

SUMMARY. 1. We developed equations which describe relationships between the relative abundance of diatom assemblages in the surface sediments of twenty-seven Sierra Nevada lakes and the present pH and acid neutralizing capacity in these lakes. 2. The

Surveys of snails occurring at water contact points used by rural people in Rhodesia show that transmission of Schistosoma haematobium is very high during the spring and early summer seasons. Although infected snails are found in all seasons, fewest

The discharge capacity of Li/SO/sub 2/ cells was examined at high current and temperatures. D cells rated at 8 Ah delivered over 7 Ah at 5A current and 55/sup 0/C, while cells discharged at 72/sup 0/C gave 7 Ah at 3A. The cells were analyzed for resi

Three marine diatoms, Skeletonema costatum, Chaetoceros debilis, and Thalassiosira gravida were grown under no limitation and ammonium or silicate limitation or starvation. Changes in cell morphology were documented with photomicrographs of ammonium

An isothermal DTA technique was developed for studying the kinetics of the heterogeneous exothermic reactions involving lithium metal and organic solvents used in the batteries. The results showed that while film forming agents such as and PC retard

The lithium reactivity of a variety of organic solvents and their mixtures was determined by measuring the exotherm initiation temperature of the organic solvents with Li using DTA. The least reactive solvent and mixtures were used to prepare electro

Radiative transfer within a hydrosol such as ocean or lake water can best be described by means of the inherent and apparent optical properties of the hydrosol. Equipment for obtaining the important optical properties of large bodies of water is desc
