Geology and ground-water resources of Fillmore County, Nebraska, with a section on chemical quality of the water
Charles Franklin Keech, V. H. Dreeszen, L. R. Petri
1968, Water Supply Paper 1839-L
Fillmore County, an area 24 miles square, lies in the eastern part of the Nebraska loess plain. Although tributaries of the Big Blue River have eroded valleys into this plain, much of the original surface is intact. Broad flats and numerous shallow undrained depressions characterize the plain. The county is...

Gas chromatographic separation and quantitative estimation of barbiturate mixtures in solid dosage forms
J. L. Allen
1968, Journal of the Association of Official Analytical Chemists (51) 619-621
A gas chromatographic method has been described for the analysis of mixed barbiturates in solid dosage forms. Analysis on a 10% SE-30 column gave good separations for butabarbital, amobarbital, secobarbital, pentobarbital, and/or phenobarbital; amobarbital is not separated adequately from pentobarbital. An internal standard, mephobarbital, is used to minimize injection errors....

On the quantitative inventory of the riverscape
Luna Bergere Leopold, Maura O’Brien Marchand
1968, Water Resources Research (4) 709-717
In the vicinity of Berkeley, California, 24 minor valleys were described in terms of factors chosen to represent aspects of the river landscape. A total of 28 factors were evaluated at each site. Some were directly measurable, others were estimated, but each observation was assigned to one of five categories...
Ground-water reconnaissance of the Santa Barbara-Montecito area, Santa Barbara County, California
K. S. Muir
1968, Water Supply Paper 1859-A
This is the third interpretive report prepared by the U.S. Geological Survey in cooperation with the Santa Barbara County Water Agency on the groundwater resources of areas along the south coast of the county. The two previous reports--one by J. E. Upson in 1951 and another by R. E. Evenson,...
Silver-bearing black calcite in western mining districts
D. F. Hewett, A. S. Radtke
1967, Economic Geology (62) 1-21
The name black calcite has been applied from time to time to a dark gray to black variety of calcite or aragonite in metalliferous ore deposits in the Western States. Most of the material shows curved, roughly rhombic cleavage. The color is due to dispersed minute grains of one or...

1967, Utah Geological and Mineralogical Survey Water-Resources Bulletin 9-I
This report presents data collected during the first part of an investigation that was started in 1963 by the U.S. Geological Survey in cooperation with the Utah Geological and Mineralogical Survey. The investigation has the purpose of providing information about the chemical quality of water in western Utah that will...
The effect of pumping large-discharge wells on the ground-water reservoir in southern Utah Valley, Utah County, Utah
R.M. Cordova, R. W. Mower
1967, Utah State Engineer Information Bulletin 18
An extensive aquifer test in southern Utah Valley, Utah County, Utah, was made during January-March 1967 by the U.S. Geological Survey in cooperation with the Utah State Engineer. The purpose of the test was to obtain data about the hydraulic characteristics of the aquifer in the valley and to determine...

This study of the ground-water conditions in Cedar Valley, Utah, was made by the U.S. Geological Survey in cooperation with the Utah State Engineer during the period July 1965-July 1966. The purposes of the study were to estimate the recharge to and the yield of the ground-water reservoir and to...
Biodegradation of dichlorodiphenyltrichloroethane: Intermediates in dichlorodiphenylacetic acid metabolism by Aerobacter aerogenes
Gary Wedemeyer
1967, Applied Microbiology (15) 1494-1495
The final product of dichlorodiphenyltrichloroethane (DDT) degradation by vertebrates is commonly considered to be dichlorodiphenylacetic acid, DDA (J. E. Peterson and W. H. Robison, Toxicol. Appl. Pharmacol. 6:321, 1964). Recently, certain organisms (A. S. Perry, S. Miller, and A. J. Buckner. J. Agr. Food Chem. 11:457, 1963; J. D. Pinto,...
A closed recirculated sea-water system
1967, Progressive Fish-Culturist (29) 133-139
Study of a virus disease in the chinook salmon (Oncorhynchus tshawytscha) necessitated the use of a marine environment to study the long range effects of the disease and to complete the life cycle of its etiologic agent. A closed recirculated sea-water system was designed for use under experimental laboratory conditions so...
A comparison of Oregon pellet and fish-meat diets for administration of sulfamethazine to Chinook salmon
D.F. Amend, J. L. Fryer, K.S. Pilcher
1967, Research Briefs: Fish Commission of the State of Oregon (13) 20-24
The absorption of sulfamethazine by yearling spring chinook salmon (Oncorhynchus tshawytscha) was compared when administered in the Oregon Pellet and a fish-meat diet. The pelleted diet delivered the drug to the fish approximately twice as efficiently as the fish-meat diet. Dosage levels are recommended for both diets, and the efficacy...
Nutritionally induced hepatomagenesis of rainbow trout (Salmo gairdneri)
1967, Research Report 70
Hepatoma in commercially reared rainbow trout (Salmo gairdneri) was first seen at this laboratory in April of 1960. The subsequent discovery of it in near epizootic proportions in other hatchery-reared rainbow trout and cutthroat trout (S. clarki) populations throughout the United States precipitated extensive research by numerous agencies. Although the...
Trends in ground-water levels in Wisconsin through 1966
Robert W. Devaul
1967, Wisconsin Geological & Natural History Survey Information Circular 9
The water supplies of Wisconsin are the State's most valuable natural resource. Although the State has abundant water supplies to maintain the perennial flow of most streams, and to sustain large increases in municipal, agricultural, and industrial use in many areas, the available supply is not distributed equally throughout the...
