This thesis is a discussion of the major bee diseases
found in Oregon with notes on minor ailments of bees and
on diseases not yet present followed by a history of the
introduction and spread of the more important diseases,
a history of bee legislation in Oregon and a discussion...
In order to develop a stimulating yet effective school-based program which elicits
a positive bone growth response, we need to understand the forces acting on the bones of
children during various high-impact activities. One activity found to promote bone
growth is drop landings from a height. We determined whether there...

This study is the second of a three-part project to determine potential locations for public transient tie-up facilities along the Columbia River. The goal of the three studies is to identify opportunities for developing a network of facilities, which will enable recreational boaters to safely traverse Oregon's portion of the...
Previous research has shown that activated carbon is effective
in inactivating certain herbicides applied as a preemergence treatment.
Studies were conducted in the greenhouse to determine the
influence of various factors on the ability of activated carbon to
inactivate herbicides applied after carbon application. Field studies
were conducted to determine...
PURPOSE: The purpose of the study was to identify a set of core competencies needed to meet the minimal requirements for high school graduation and to test their level of acceptance by administrators, counselors, teachers and parents in 50 Oregon secondary school districts. PROCEDURES: Utilizing the 1136 existing graduation competencies...
Purpose of the Study The primary focus of this study was to compare Iowa Tests of Educational Development (ITED) subtest scores with achievement letter grades (A, B, C, D, and F) in vocational education classes at Bartlett High School, Anchorage, Alaska. The two secondary purposes of the study were to...
Studies were conducted in 1969 and 1970 to evaluate the
effectiveness of an experimental herbicide, SD 30053 (alanine,
N-benzoyl-N-(3, 4-dichlorophenyl)-, ethyl ester), for wild oat
(Avena fatua L.) control in winter cereals.
The 1969 field studies showed that postemergence applications
of SD 30053 were effective in controlling wild oats. Wild...
Investigations were made in the field, greenhouse, growth
chamber, and laboratory to: (a) observe the general activity of N-
(phosphonomethyl)glycine (glyphosate); (b) determine the extent of its
interaction with certain s-triazine herbicides; and (c) find an explanation
for such an interaction.
Greenhouse and growth chamber studies substantiated other
observations that...
Several studies were conducted to determine the effect of weed
density on herbicide efficacy. Diuron [3-(3, 4- dichlorophenyl) -1, 1-
dimethylurea] was tested on various densities of Italian ryegrass
(Lolium multiflorum Lam. ) under greenhouse and field conditions.
Cycloate (S-ethyl N-ethylthiocyclohexanecarbamate) was tested on
green foxtail (Setaria viridis (L. )...

A program, Color Choropleth Mapping System (CCMS), has
been developed to provide high quality color choropleth maps at
the Geography Department at Oregon State University. The program
operates interactively and is menu-driven. When developing the
software for mapping programs, programmers need to be aware of
cartographic theory, as well as...
Abstract: A series of 23 thin, mostly mud-silt turbidites are found interspersed between larger, well-dated and regionally correlated paleoseismic sandy turbidites that extend along most of the Cascadia margin, northwestern United States. Investigation of the structure, distribution, and sedimentology of these thin mud-silt units supports the interpretation of these units...
The purpose of this study was to examine conditions under which functional ability predicts relocation of older persons. Data for this study came from a sample of 6,225 respondents aged 70 or older, who were interviewed both at Wave 1 (1993) and 2 (1995) of a longitudinal national survey of...
Greenhouse and growth chamber experiments were conducted with
the following objectives: (a) to study the effects of N-1-naphthylphthalamic
acid (naptalam) on shoot and tuber production, rhizome transformation,
and growth of yellow nutsedge (Cyperus esculentus L.) plants;
(b) to study the effects of N-phosphonomethyl glycine (glyphosate) on
nutsedge plants at different...
