During the Spring of 1969, 47 surface soil samples (0 to 15 cm)
as well as foliage samples of subterranean clover were collected from
32 selected western Oregon pastures, in an effort to determine their
molybdenum status and to evaluate the use of anion exchange resin
method as a means...
This thesis presents an economic analysis for a proposed toll
road which is to separate different types of traffic such as pedestrians,
slow speed vehicles and high speed motor vehicles, and to
divert through traffic from the local roads. The use of a toll road
usually provides significant savings in...
The genus Coenonycha contains 30 described species of small to
medium sized scarabs. They are found in the arid and semi-arid
regions of western United States and northern Baja California. The
adults feed at night on several genera of xerophylous plants.
An examination of the male genitalia of the 19...
The purpose of this thesis was (1) to determine a dietary regimen which would produce the greatest incidence of cardiac calcification in the cotton rat and (2) to determine the fatty acid composition of heart tissue.
Maximum incidence of cardiac calcification occurred from feeding torula yeast ration supplemented with 0.5%...
The reproductive characteristics of the mountain cottontail
rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269
specimens collected in central Oregon between 28 May 1968 and
28 August 1969.
Male rabbits were in breeding condition between mid-February
and 3 July 1969. Nearly 77% of the females bore four litters between
7...
The thesis area includes 54 square miles of the southeastern
Cuddy Mountains in west-central Idaho. The oldest rocks within the
area are plutonic phases of the Jurassic Cuddy Mountain complex.
These and Cretaceous (?) intrusive and associated (?) extrusive rocks
and nearby Triassic to Early Jurassic metasedimentary and metavolcanic
rocks...
There are six types of Cl. botulinum (Types A, B, C, D, E,
and F). The differentiation between these types is based upon the
antigenic structure of the toxin. Many strains of these various types
have been isolated. In addition, a number of nontoxigenic "type Elike"
strains have come to...
The thesis area includes 44 square miles of the Centennial
Range in Beaverhead County, Montana, and Clark County, Idaho.
The rocks exposed in the area range in age from Precambrian
to Recent and have been divided into 23 mapped units. Pre-Belt
metamorphic basement rocks are overlain unconformably by 3,433
feet...
This programmed text covers the basic elements of the theory
of modulation. It is by no means a comprehensive reference to
modulation topics. The text is designed to introduce the student to
modulation in general terms. After successful completion of this
text, the student should be able to advance to...
A study was conducted to determine the quantity and character
of substances leached from logs floating in water, and the rate of
leaching of these substances. The species of wood studied were Douglas
fir and ponderosa pine. The research was carried out in a controlled
laboratory environment with log sections...
