This report measures the effects of logging on the production and yield of Coho salmon, coastal cutthroat, and steelhead trout in small coastal streams. It contains descriptions of the physical and biological environment before logging, and describes some immediate effects of logging, such as such as a decrease in dissolved...
This thesis documents a new language which facilitates
the construction of Turing machines. The language translator
is written in Compass and has been debugged and is
available for use on the CDC 3300.

Moisture has long been identified as one of the major
limiting factors in the distribution of agricultural land use practices.
However, the importance of any environmental element can only be
determined by considering how it is affected by its relationship with

A rheostat is an adjustable resistor so constructed that its resistance may be changed without opening the circuit in which it may be connected. Conventional rheostats are adjusted mechanically. This thesis presents a method of adjusting resistance electrically by varying the light intensity incident on the surface of a photoconductive...
In freshwater the crayfish, Pacifasticus leniusculus, maintains
sodium balance by absorbing sodium against a large concentration
gradient. The site of uptake is the gills. The rate of uptake is
regulated and can be increased by depleting the animals of sodium
Neither the mechanism of sodium transport or the regulatory mechanism...
Sporadic outbreaks of diacetyl off-flavor in beer are a serious
economic problem to the brewing industry. Studies were carried out
in an attempt to improve the understanding of the problem and to experiment
with new ways of controlling this defect.
The Owades and Jakovac method of diacetyl determination as
modified...
