Within the United States, the number of "out" Lesbian, Gay, and Bisexual (LGB) individuals attending a college or university is on the rise (Rosario, Schrimshaw, Hunter & Braun, 2006). With this increase, the new and/or different ways that lesbian and gay individuals can present and express their sexual orientation has...
Plate loading tests in rock are deceptively simple tests to perform.
Consequently, many varieties have been developed in the past
60 years. From each of the varieties various investigators have added
their own developments and modifications, some good, and some not so
good. The result has been a confusion of...
An examination of the technical and historical literature
concerning the discovery and development of antibiotics suggests the
possible existence of an era of discovery. This era appears to have
a well-defined beginning (about 1940) and a well-defined close (about
1960). It is the purpose of this dissertation to examine the...
Samarium-neodymium data for authigenic ferromanganese
sediments from the oceans indicate that the Atlantic, Pacific, and
Indian Oceans each have a distinct range in Nd isotopic composition,
all of which are far less than ¹⁴³Nd/¹⁴⁴Nd ratios of source rocks with
oceanic affinities. Direct measurements of the Nd isotopic composition
of seawater...
Centuries of continuous grain cropping in northern Africa have
reduced N levels in soils to a degree such that agricultural production
is now largely dependent upon nitrogen fertilizer. Through the
identification of highly effective legume and Rhizobium strain combinations,
the production of protein-rich livestock forage and green
manure can be...
This thesis asserts that faculty are the critical resource for the integration of distance
education by postsecondary institutions. The major barriers to the participation and
adoption of distance education center around faculty. This manuscript thesis incorporates a
series of articles to develop applied frameworks and strategies that place faculty at...
Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...
Sex steroids, follicle stimulating hormone (FSH),
luteinizing hormone (LH) and gonadotropin releasing hormone
(GnRH) were measured in monosex and mixed sex populations of
rainbow trout during early development. Steroids declined
following fertilization, increased at hatch, then fell and
remained constant thereafter. Trends toward differences in
steroids between males and females...
Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee,
Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed
growers in western North America who use populations of this bee for
pollination. Basic studies were conducted to determine the etiology of
this disease and the course of...
The simplified equations of motion proposed by Morton to determine
the extent of vertical travel of a forced plume in a linear
density stratified environment were re-written and solved in a way
which allowed them to be applied to any non linear profile of density.
For application to any specific...
This is a description of the physical setting and distribution of plant and animal species near the mouth of the Salmon River. Intertidal invertebrates are emphasized. A more marine location is contrasted with a more estuarine site.

Environmental restrictions have induced many sawmills to seek alternatives to pentachlorophenol (penta) or similar chlorinated phenols to control fungal sapstains on green lumber. Five alternative preventives were evaluated against a traditional penta product (Permatox 101) on Douglas-fir, hem-fir, and pine lumber in an accelerated 6-week test on small specimens in...
Production of hardwood lumber (mostly red alder) has been a small but growing part of the forest products industry in the Pacific Northwest. In laboratory tests, Rodewod® 200 EC plus borax protected alder at nearly all levels tested. Eight other chemicals provided some protection at the highest level tested. Fungal-stain...
Tanoak lumber might supplement the supply of white oak for boat construction, as the tree has extremely thick sapwood that can be pressure- treated readily with preservatives.
One-inch tanoak lumber was kiln -dried to 3 different moisture content ranges, then pressure -treated with water -borne preservatives. Some unseasoned lumber was...
Environmental restrictions have induced many sawmills to seek alternatives to pentachiorophenol (penta) and similar chlorinated phenols for controlling mold and fungal stains on green lumber during storage and shipment. For that purpose, ten alternative stain preventives were evaluated against a traditional penta product (Permatox 101) on studs of Douglas-fir [Pseudotsuga...
This summary of the 1958 inspection of the T. J. Starker Post Farm is issued as a supplement to the detailed Progress Report 11, October 1957. Complete Progress reports to be issued at intervals of 2-5 years will describe post series mentioned here and will summarize previous work.
Two techniques widely recommended for managing Port-Orford-cedar root disease (caused by the introduced pathogen Phytophthora lateralis) are vehicle washing and roadside sanitation. However, their effectiveness has never been tested using a sample-based approach. Vehicle washing effectiveness was evaluated using Port-Orford-cedar seedling baits and a double-washing method. Washing with water can...
The primary goal of a Bulk Tank Milk Culture (BTMC) is to determine what types of bacteria are in milk. Bacteria originate from three sources: udder tissue infected with a contagious bacteria, cow's environment, including milking equipment, and bacteria flora that reside on the teat or udder skin.
Use this...

The nonlinear dynamics of unstable alongshore currents in the nearshore
surf zone over variable barred beach topography are studied using numerical
experiments. These experiments extend the recent studies of Allen et al. [1996]
and Slnn et al. [1998], which utilized alongshore uniform beach topographies by
including sinusoidal alongshore variation to...
