1998, ASTM Special Technical Publication STP1333
A standard methodology for assessing the impacts of simulated solar ultraviolet-B radiation (UV-B) on aquatic invertebrates was established. A solar simulator was used to expose a variety of aquatic invertebrates to different levels of UV-B. The simulator was calibrated as close as possible to match local ambient solar radiation measured...
The chemical evolution of Kurnub Group palcowater in the Sinai-Negev province - A mass balance approach
E. Rosenthal, B.F. Jones, G. Weinberger
1998, Applied Geochemistry (13) 553-569
The chemical evolution of the Kurnub Group paleowater was studied starting from rainwater in recharge areas of the Sinai and along groundwater flowpaths leading to the natural outlets of this regional aquifer. This was achieved by investigating the chemical composition of groundwater, ionic ratios, degrees of saturation with common mineral...

K. Fynn-Aikins, P.R. Bowser, D. C. Honeyfield, J.D. Fitzsimons, H. G. Ketola
1998, Transactions of the American Fisheries Society (127) 747-757
Broodfish of Atlantic salmon Salmo salar were fed either thiamin-deficient diets fortified with 0.05% and 0.1% amprolium chloride (Amp, a thiamin antagonist) or thiamin-sufficient diets (0% Amp and ASD2-30, a U.S. Fish and Wildlife Service open-formula feed) for 6 months before spawning. We observed Cayuga syndrome (CS) only in the fry produced...

Hydrology and quality of ground water in northern Thurston County, Washington
B. W. Drost, G. L. Turney, N. P. Dion, M. A. Jones
1998, Water-Resources Investigations Report 92-4109
Northern Thurston County is underlain by as much as 1,800 feet of unconsolidated deposits of Pleistocene Age that are of glacial and nonglacial origin. Iterpretation of approximately 1,140 drillers' logs led to the delineation of seven major geohydrologic units, four of which are significant aquifers. Precipitation ranges from about 35...
