Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...
The degree to which camping is related to selected characteristics of river terraces along the Rogue Waterway, Oregon has been analyzed. Previous attempts to formulate models relating campsite choice to characteristics of the natural environment focused on camping parties engaged in auto-camping and the aggregate population behavior rather than on...
A long standing problem has been the question of what maps to select for acquisition in a college map library. This thesis addresses
the problem and provides a carto-bibliography of basic maps for a map library. Following a brief review of pertinent literature, criteria for evaluation and selection of maps...
As non-renewable resources dwindle and costs increase, it becomes ever more important for people to understand and control their electricity usage. Eco-feedback devices are being developed to increase user awareness and reduce consumption. In order for feedback devices to be successfully adopted into the home, however, they must be appealing...
A statistical analysis of extreme chinooks in Montana as they
relate to large scale atmospheric circulation changes is the subject
of this thesis.
A mean chinook situation was identified which indicated that a
critical pattern of the surface flow always contained a Polar or
Arctic airmass which overspread the prairie...
EDLAN is a simple, inexpensive local area network suitable for
educational applications. In EDLAN, a number of personal computers are
connected through an RS-485 global bus which carries the data
transmission among the computers. CSMA/CD protocol is used to control
the access of the global bus. The communications are controlled...
Investigations were conducted to study in detail some biochemical and physiological aspects of ripening in pears. Anjou pears
picked at different degrees of maturity were treated with Ethrel
(2-chloroethane phosphonic acid), 4000 ppm, and ethylene, 500 ppm,
for different lengths of time. Respiration rate was measured twice
daily and changes...

parks in Colombia was described; 2) The status, as of August,
1974, of the areas administered by the Colombian Renewable Natural
Resources Development Institute (INDERENA) was summarized; 3) An
analysis of major...
An experimental formulation of 9 -oxodec-trans-2-enoic acid, the major component of honey bee (Apis mellifera L.) queen pheromone, was tested for its effect on worker foraging behavior in the pollination of sweet cherries (Prunus avium L. ). The test formulation consisted of a solid beeswax cylinder impregnated with a measured...
