Liquefaction sites, Imperial Valley, California.
T. L. Youd, M.J. Bennett
1983, Journal of Geotechnical Engineering (109) 440-457
Sands that did and did not liquefy at two sites during the 1979 Imperial Valley, Calif., earthquake (ML = 6.6) are identified and their properties evaluated. SPT tests were used to evaluate liquefaction susceptibility. Loose fine sands in an abandoned channel liquefied and produced sand boils, ground fissures, and a...
Carbonatite tuffs in the Laetolil Beds of Tanzania and the Kaiserstuhl in Germany
R. L. Hay, J. R. O’Neil
1983, Contributions to Mineralogy and Petrology (82) 403-406
Carbonatite lava and tephra are now well known. The only modern eruptive carbonatites, from Oldoinyo Lengai, Tanzania, are of alkali carbonatite, whereas all of the pre-modern examples are of calcite or dolomite. Chemical and stable isotope analyses were made of separate phases of Pliocene carbonatite tuffs of the Laetolil Beds...
Analysis of spurious oscillation modes for the shallow water and Navier-Stokes equations
Roy A. Walters, G. F. Carey
1983, Computers and Fluids (11) 51-68
The origin and nature of spurious oscillation modes that appear in mixed finite element methods are examined. In particular, the shallow water equations are considered and a modal analysis for the one-dimensional problem is developed. From the resulting dispersion relations we find that the spurious modes in elevation are associated...
Incorporation of prior information on parameters into nonlinear regression groundwater flow models: 2. Applications
Richard L. Cooley
1983, Water Resources Research (19) 662-676
This paper investigates factors influencing the degree of improvement in estimates of parameters of a nonlinear regression groundwater flow model by incorporating prior information of unknown reliability. Consideration of expected behavior of the regression solutions and results of a hypothetical modeling problem lead to several general conclusions. First, if the...
Branched-chain amino acid aminotransferase activity in the tissues of lake trout
S. G. Hughes, G. L. Rumsey, M.C. Nesheim
1983, Comparative Biochemistry and Physiology, Part B: Comparative Biochemistry (76) 429-431
1. The enzyme branched-chain amino acid aminotransferase (BCAT) was found in five tissues of fingerling lake trout, Salvelinus namaycush, (listed in order of decreasing tissue specific activity): posterior kidney, skeletal muscle, gill, liver, and anterior kidney.2. This pattern is consistent with that found in other animals.3. The results of this...
Factors affecting dietary requirement and deficiency signs of L-tryptophan in rainbow trout
H. A. Poston, G. L. Rumsey
1983, Journal of Nutrition (113) 2568-2577
Two experiments were conducted to determine the concentration of dietary tryptophan needed for optimal growth and survival of fingerling rainbow trout (Salmo gairdneri), to characterize signs of tryptophan deficiency, and to ascertain the effects of niacin on deficiency signs. Test diets containing either hydrolyzed or intact casein were fed with...
Geo-botanical evidence of Late Quaternary mass wasting in block field areas of Virginia
Cliff R. Hupp
1983, Earth Surface Processes and Landforms (8) 439-450
Studies of block fields at Massanutten Mountain, Virginia, document and provide information on the magnitude and frequency of mass movement on these coarse-grained slopes. Although Pleistocene periglacial climate may have facilitated original formation of block fields, some block fields now continue to spread downslope during intense runoff events. Present block-field...

Selective control of common carp: Ineffectiveness of 2-(digeranylamino)-ethanol (GD-174) in pond trials
P.A. Gilderhus, R.M. Burress
1983, North American Journal of Fisheries Management (3) 61-66
The candidate piscicide, 2‐(digeranylamino)‐ethanol, (commonly known as GD‐174) was subjected to efficacy trials in ponds under a wide variety of conditions. Results of the trials were disappointing considering that laboratory tests had shown the compound to be selectively toxic to common carp (Cyprinus carpio). Results of pretreatment, on‐site toxicity tests...
The use of sagebrush (Artemisia) as a biogeochemical indicator of base-metal deposits in Precambrian rocks of west-central Colorado
T.G. Lovering, J. A. Hedal
1983, Journal of Geochemical Exploration (18) 205-230
The efficacy of sagebrush (Artemisia) as a biogeochemical indicator of base-metal mineralization in stratabound Precambrian ore deposits in west-central Colorado was investigated by collecting new (mostly flowering) growth from several sagebrush shrubs over and near five such deposits in three different areas. These are the Sedalia mine and two mines...

A reexamination of the effects of adsorbates on the Raman spectrum of gibbsite
K.W. Cunningham, M. C. Goldberg
1983, Soil Science (136) 102-110
Previous workers have attributed substantial changes in the Raman intensities of the OH stretching bands in solid, powdered gibbsite of surface area 10 m2/g to surface interactions with the adsorbates 093Ca2+,HxPO43x- and SiO2.xH2O. These changes apparently resulted from an unsatisfactory Raman measurement procedure as a re-examination using an internal intensity...

Cuprian fraipontite and sauconite from the Defiance-Silver Bill mines, Gleeson, Arizona.
E.E. Foord, J. E. Taggart, N. M. Conklin
1983, Mineralogical Record (14) 131-132
XRD studies have shown the fine-grained, light blue-green mineral previously identified as turquoise or chrysocolla to be the rare species fraipontite + or - admixed sauconite. Composite microprobe and XRF analyses gave SiO2 24.8, Al2O3 17.3, CaO 0.34, CuO 5.2, ZnO 40.95, H2O (ign. loss, 900oC) 12.8, = 101.39, yielding...
EFFICIENT TRANSFER OF DATA BETWEEN MAPS OF DIFFERENT PROJECTIONS.
John P. Snyder
1983, Conference Paper, Technical Papers of the American Congress of Surveying and Mapping
There are several ways to transfer data from an existing map to another map by computer. If the projection and parameters of both maps are known, analytic formulas may be used to convert rectangular coordinates of the first map to latitude and longitude and then to rectangular coordinates of the...
Elevated DDE and toxaphene residues in fishes and birds reflect local contamination in the lower Rio Grande valley Texas USA
Donald H. White, C. A. Mitchell, H.R. Kennedy, A. J. Krynitsky, M. A. Ribick
1983, Southwestern Naturalist (28) 325-334
A potential organochlorine pesticide problem was identified near Mission, Texas, by the National Park Monitoring Program. Fish samples from this site have consistently contained elevated levels of DDE since 1968. Surveys were made in 1976, 1978, and 1979 to determine the extent of organochlorine pesticide contamination in fishes and birds...

Temporal patterns of seed use and availability in a guild of desert ants
Patricia Mehlhop, Norman J. Scott Jr.
1983, Ecological Entomology (8) 69-85
1Temporal patterns of seed use were studied from late winter to autumn in three species of seed-harvesting ants in the Sonoran Desert. Measures of effective foraging activity, dietary niche breadth and dietary niche overlaps were obtained each month and were tested for correlation with estimates of the...
Inclusion body disease of cranes: A serological follow-up to the 1978 die-off
D. E. Docherty, Renee I. Romaine
1983, Avian Diseases (27) 830-835
A herpesvirus was isolated from captive cranes involved in a 1978 die-off. Neutralizing antibody to this virus was detected in this captive population as early as 1975 and consistently thereafter through 1979. Exposure to the virus evidently occurred at least 2 1/2 years before the die-off, without causing any mortality...
