Chemical reaction studies by frequency response methods

Creator:: Knudsen, Robert Allen
Abstract:: A method for measuring chemical reaction rates in order to distinguish between different reaction mechanisms is presented. This method was used to study zero -, first- and second -order reactions by analyzing the output response to a sinusoidal input of reactant concentrations in an isothermal continuous stirred tank reactor. The...

Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...
