Excretion of the lampricide Bayer 73 by rainbow trout Excretion of the lampricide Bayer 73 by rainbow trout

Urinary excretion of the 2-aminoethanol salt of 2′, 5-dichloro-4′-nitrosalicylanilide (Bayer 73) in rainbow trout (Salmo gairdneri) was measured after exposure of the trout to Bayer 73 and also after intraperitoneal (ip) injection of the lampricide. Fish exposed to 0.05 mg/litre of Bayer 73 for 12 h quickly began to excrete residues in the urine. The largest amount of Bayer 73 was...

b values and ω^−γ seismic source models: Implications for tectonic stress variations along active crustal fault zones and the estimation of high-frequency strong ground motion b values and ω^−γ seismic source models: Implications for tectonic stress variations along active crustal fault zones and the estimation of high-frequency strong ground motion

In this study the tectonic stress along active crustal fault zones is taken to be of the form , where is the average tectonic stress at depth y and Δσp(x, y) is a seismologically observable, essentially random function of both fault plane coordinates; the stress differences arising in the course of crustal faulting are derived from Δσp(x, y). Empirically known frequency of occurrence...

Better utilization of ground water in the Piedmont and mountain region of the southeast Better utilization of ground water in the Piedmont and mountain region of the southeast

The development of water supplies for domestic consumption, and for those commercial and industrial uses requiring relatively pure water, has followed a pattern in the Piedmont and mountain areas of the southeast similar to that in most other humid areas. The first settlers utilized seepage springs on hillsides. Such springs occur along steep slopes where the water table intersects the...
