A complete solution, exact to second-order, for wave motion
forced by a hinged-wavemaker of variable-draft is presented. A
solution for a piston type wavemaker is also obtained as a special
case of a hinged-wavemaker with negative infinite draft. The
existing Stokes inviscid theories for mass transport is extended to
include...
Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...
Laboratory and field studies were conducted at Pendleton, Oregon, during 1983 and 1984 to evaluate germination and growth characteristics of five jointed goatgrass (Aegilops cylindrica Host) accessions collected from sites in Echo, Ione, Pendleton, Condon, and Elgin, Oregon. Spikelets were germinated for 27 days at room (23 +̲ 2 C)...
The purpose of this study was to identify the dry season
vegetable production sources of information, technical knowledge
base and needs of women farmers expressed by the women farmers
themselves in Ngabu Agricultural Development Division, Malawi,
Central Africa.
The objectives were to identify the following aspects of dry
season vegetable...
Farm equipment is becoming an increasingly important
financial asset for many farmers. Tractors probably represent the
single largest component of equipment asset value. As such, changes
in tractor values can have a dramatic effect on a farmer's financial
situation. Changes in equipment value can be attributed to
depreciation and the...
The known distribution of beluga whales ranges from sub-Arctic to Arctic waters where they migrate in pods in response to environmental factors such as the presence of sea ice and prey. This study uses bivariate and multivariate analysis techniques to measure how environmental covariates are associated with the spatial-temporal distribution...
California brome (Bromus carinatus Hook & Arn), is
considered an important weed infesting wheat and grass seed
fields in the Willamette Valley of Oregon. Field and
greenhouse experiments were conducted to study some
biological aspects to develop more efficient management
strategies.
A field experiment was conducted to determine the
effect...
The lack of information regarding the inheritance of the duration and rate of
grain filling, and the possible relationship between grain fill and grain protein
content in wheat prompted this study.
Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late
maturing cultivars adapted to Oregon, 'Stephens' and...
The main objective of this study was to offer an alternative methodology for
forest sector modeling in developing economies. To this effect, a policy preference
function was developed and estimated using data from the forest sector of the Cote
d'Ivoire.
The justification for this alternative framework for forest sector analysis...
