Six headwalls in the central Oregon coast range were selected for study of soil engineering properties and vegetativecharacteristics important for analysis of slope stability. The headwalls were considered representative of those which would be candidates for timber leave areas due to geomorphic and topographic features, including steepness of slope and...
The purpose of the study was to assess county extension agents'
knowledge of geotextiles; to determine their current level of
information and their location on an adoption-diffusion curve; and to
determine the agents' attitudes toward the potential use of
geotextiles in agriculture, specifically in soil erosion control.
A questionnaire was...
The middle to upper Eocene Tillamook Volcanics form the basement in the Rock Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and andesites were erupted as shield volcanoes seaward of the strandline ontop of an older deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...
Tolerance analysis and synthesis plays a vital role in the success of a product design because it directly affects product quality and manufacturing cost. It also affects manufacturing process selection and planning. This research provides a review of several commonly used assembly tolerance analysis models and evaluation of their limitations....
The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...
The northern Los Angeles basin is influenced by two structural styles: the west-trending compressional Transverse Ranges to the north, and the strike-slip Peninsular Ranges to the south. The interaction of these two structural styles has resulted in a complex fold fault belt at the northern margin of the Los Angeles...
The major portion of Pacific whiting (PW) is commercialized in the form of frozen surimi. Alternative products for PW were investigated focusing on fresh surimi and texturized meat from PW mince. Fresh surimi is made without additives and kept refrigerated instead of frozen. Texturized meat is a meat-like product made...
The purposes of this study were:1) to review the land use history of Oak Creek watershed since European settlement. And 2) to consider the human-caused impacts and their effects associated with different land uses. The study area was classified into three land use patterns: residential,agricultural, and forested areas.Since the European...
A characterization of the antigenic determinants (epitopes) of the glycoprotein (G) of infectious hematopoietic necrosis virus (IHNV) was made with different regions of the G gene expressed in Escherichia coli. A cDNA copy of the G gene was divided into four fragments after Taq I digestion and these fragments were...
Nutrition and diet are significantly interrelated with oral health and disease.
The control of diet and nutrient intake and good oral hygiene are important elements
in the prevention and treatment of dental caries and periodontal disease.
Prevention of dental disease is the major focus of dentistry today, and dietary counseling...
The Sulaiman foldbelt is an active and conspicuous tectonic
feature on the northwestern margin of the Indo-Pakistani plate.
Seismic reflection data have been combined with surface geological
mapping and drillhole data to interpret the structural style and
tectonic shortening of the eastern Sulaiman foldbelt and its adjacent
foredeep. The data...
The environment has been exposed to a number of hazardous chlorinated
organic compounds. These compounds may be anaerobically biotransformed by
sequential reductive dechlorination reactions in which the chlorine atoms are
replaced with hydrogen atoms. Because reductive dechlorination processes may
occur very slowly in the environment and chlorine position affects the...
This thesis describes the design of a Reduced Instruction Set Computer. Its instruction memory utilizes a unique cache architecture and a two-stage memory pipelining technique. Because of the bandwidth of the 64-bit instruction bus, instruction prefetching is possible and is implemented. The data memory is bridged by a four-way set-associative...
Increasing automation and highly flexible manufacturing processes cause increasing complexity for manufacturing system. FMS (Flexible Manufacturing System) is an approach to solve this problem. Since the elements of the FMS and manufacturing process performance are closely interrelated, the application of simple modeling and emulation techniques in the planning stages for...
Previous research suggests that fabric store customers
are not satisfied with the service provided in fabric
stores. According to the EBM consumer behavior model
(Engle, Blackwell, Miniard, 1986) and Oliver's consumer
satisfaction/dissatisfaction model (1981), fabric store
customers' dissatisfaction may be a result of their
unfulfilled service expectations. The purpose of...
The new CMOS folded source-coupled logic (FSCL)
technique intended for mixed-mode integrated circuits has
been designed. It has advantages over conventional CMOS
circuit in terms of reduced current spike, circuit delay,
logic flexibility, and layout density. A simple CPU
implemented in 2 μm CMOS technology with a 5.0 volt supply...
The photosynthetic activities, the pigmentation and the chloroplast
membrane polypeptides of several mutants of the green alga, Scenedesmus
obliquus, with complete or limited deficiencies in the light-harvesting
complex of photosystem II are characterized and compared to those of the
normal phenotype.. The principal phenotype examined in this study, K0 -9,...
Microcomputers are being used in teaching and learning
mathematics. This paper examines ways that computers can be used
to enhance teaching in precalculus mathematics. The advantages of
computers discussed are: 1) instant access to graphs, 2) examples
that are not oversimplified to make computations manageable, 3)
encouragement of hypothesizing and...
