The Gibbs free energy of formation of nukundamite (Cu3.38Fe0.62S4) was calculated from published experimental studies of the reaction 3.25 Cu3.38Fe0.62S4 + S2 = 11 CuS + 2 FeS2 in order to correct an erroneous expression in the published record. The correct expression describing the Gibbs free energy of formation (kJ·mol−1) of nukundamite relative to the elements and ideal S2 gas is ΔfG

Na+-K+-2Cl−cotransporter abundance and location was examined in the gills of Atlantic salmon (Salmo salar) during seawater acclimation and smolting. Western blots revealed three bands centered at 285, 160, and 120 kDa. The Na+-K+-2Cl−cotransporter was colocalized with Na+-K+-ATPase to chloride cells on both the primary filament and secondary lamellae. Parr acclimated to 30 parts per...

A model system was used to study bacterial fish pathogen transmission between the freshwater bivalve Amblema plicata and two strains (Nauyuk and Labrador) of Arctic char Salvelinus alpinus. Aeromonas salmonicida, the cause of fish furunculosis, was readily transmitted from Arctic char to A. plicata and vice versa via simple cohabitation. Clinical furunculosis was artificially established...

The hormones responsible for the regulation of the teleostean gill Na+–K+–2Cl− cotransporter have not been elucidated. With Western blotting and immunocytochemistry, Na+–K+–2Cl− cotransporter abundance and localization were examined in the gills of Atlantic salmon (Salmo salar) following 2-week treatment with growth hormone (GH; 5.0 μg · g−1), cortisol (50 μg · g−1), and both hormones in

Perkinsus marinus, the cause of serious losses of the eastern oyster Crassostrea virginica, secretes extracellular proteins (ECP) in culture (in vitro) including serine proteases. The production of similar ECP in the eastern oyster (in vivo) and their role in pathogenicity, however, remain to be elucidated. The induction and dissemination of these proteins within infected eastern oysters...

Overharvest and habitat alteration have led to a collapse of most commercial Atlantic sturgeon(Acipenser oxyrinchus oxyrinchus)fisheries while pushing the species to rarity or extirpation in most of its historical range. A biologically sound conservation program for this species requires knowledge of its genetic diversity and of the evolutionary relationships among geographic populations...

Atlantic salmon (n = 1682) from 27 anadromous river populations and two nonanadromous strains ranging from south-central Maine, USA to northern Spain were genotyped at 12 microsatellite DNA loci. This suite of moderate to highly polymorphic loci revealed 266 alleles (5–37/locus) range-wide. Statistically significant allelic and genotypic heterogeneity was observed across loci between all...

Water-resources data for the 1999 water year for Ohio consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at 120 gaging stations and 69 partial-record sites; water levels at 187 observation wells and 26...

The estimated production during 2000 of construction aggregates, crushed stone, and construction sand and gravel increased by about 2.6% to 2.7 Gt (3 billion st), compared with 1999. The expansion that started in 1992 continued with record production levels for the ninth consecutive year. By commodity, construction sand and gravel production increased by 4.5% to 1.16 Gt (1.28 billion st)...

Part of the 2000 annual review of the industrial minerals sector. A general overview of the ball clay industry is provided. In 2000, sales of ball clay reached record levels, with sanitary ware and tile applications accounting for the largest sales. Ball clay production, consumption, prices, foreign trade, and industry news are summarized. The outlook for the ball clay industry is also...
