Pressure increases, the formation of chromite seams, and the development of the ultramafic series in the Stillwater Complex, Montana Pressure increases, the formation of chromite seams, and the development of the ultramafic series in the Stillwater Complex, Montana
This paper explores the hypothesis that chromite seams in the Stillwater Complex formed in response to periodic increases in total pressure in the chamber. Total pressure increased because of the positive δV of nucleation of CO2 bubbles in the melt and their subsequent rise through the magma chamber, during which the bubbles increased in volume by a factor of 4–6. By analogy with the...

Evaluation of the anesthetic metomidate for the handling and transport of juvenile American shad Evaluation of the anesthetic metomidate for the handling and transport of juvenile American shad
Juvenile American shad (Alosa sapidissima) were exposed to three levels of metomidate (0.0 = control, 0.5, and 1.0 mg/L) and three types of sedation or handling (none, sedation only, and handling after sedation) to determine the efficacy and safety of the drug for use in transport and handling of this species. Mean sedation times were 9 and 3 min, and mean recovery times were 6 and 7 min
