Efficacy of benzocaine as an anesthetic for salmonid fishes Efficacy of benzocaine as an anesthetic for salmonid fishes
Benzocaine was tested in the laboratory to determine the effective concentrations for anesthetizing juvenile chinook salmon Oncorhynchus tshawytscha and rainbow trout O. mykiss (formerly Salmo gairdneri). Tests were conducted at three water temperatures, in waters ranging from very soft to very hard, and with groups of rainbow trout from 5 to 47 cm long and chinook salmon 20 cm long...

Analysis of antimycin A by reversed-phase liquid chromatography/nuclear magnetic-resonance spectrometry Analysis of antimycin A by reversed-phase liquid chromatography/nuclear magnetic-resonance spectrometry
A mixture of closely related streptomyces fermentation products, antimycin A, Is separated, and the components are identified by using reversed-phase high-performance liquid chromatography with directly linked 400-MHz proton nuclear magnetic resonance detection. Analyses of mixtures of three amino acids, alanine, glycine, and valine, are used to determine optimal measurement conditions

Direct-current vertical electrical-resistivity soundings in the Lower Peninsula of Michigan Direct-current vertical electrical-resistivity soundings in the Lower Peninsula of Michigan
Ninety-three direct-current vertical electrical-resistivity soundings were conducted in the Lower Peninsula of Michigan from June through October 1987. These soundings were made to assist in mapping the depth to brine in areas where borehole resistivity logs and water-quality data are sparse or lacking. The Schlumberger array for placement of current and potential electrodes was used for...

A macrophyte submodel for aquatic ecosystems A macrophyte submodel for aquatic ecosystems
A macrophyte submodel has been incorporated and tested in CE-QUAL-R1, a one-dimensional, vertically averaged model of reservoir water quality. A quasi two-dimensional scheme was necessary to represent the spatial relationship of macrophytes in reservoirs adequately. The macrophyte processes modeled were photosynthesis, dark respiration, excretion and nonpredatory mortality. Process...

Disposition of pentachlorophenol in rainbow trout (Salmo gairdneri): Effect of inhibition of metabolism Disposition of pentachlorophenol in rainbow trout (Salmo gairdneri): Effect of inhibition of metabolism
The accumulation kinetics of pentachlorophenol (PCP) were investigated in rainbow trout (Salmo gairdneri) in the absence and presence of 25 mg/1 salicylamide, an inhibitor of PCP metabolism. After exposure to 5 μg/1 PCP over 1–96 h, the amount of PCP in the whole fish, its concentration in water and the total amount of metabolites (water, whole fish and bile) were measured. Equations for...

Reversed-phase thin-layer chromatography of homologs of Antimycin-A and related derivatives Reversed-phase thin-layer chromatography of homologs of Antimycin-A and related derivatives
Using a reversed-phase high-performance liquid chromatographic (HPLC) technique, a mixture of antimycins A was separated into eight hitherto unreported subcomponents, Ala, Alb, A2a, A2b, A3a, A3b, A4a, and A4b. Although a base-line resolution of the known four major antimycins Al, A2, A3, and A4 was readily achieved with mobile phases containing acetate buffers, the separation of the new

Reversed-phase high-performance liquid chromatography of unsubstituted aminobenzoic acids Reversed-phase high-performance liquid chromatography of unsubstituted aminobenzoic acids
High-performance liquid chromatographic (HPLC) characteristics of three position isomers of aminobenzoic acids (potential metabolites of important anesthetic drugs), were delineated with respect to their interactions with various mobile phases and stationary phases. HPLC with five hydrocarbonaceous phase, I?-cyclodextrin silica (CDS), macrophase MP-1 polymer (MP), macroporous polystyrene
