The filbert is propagated by layerage and a faster method is
needed to keep pace with the rapidly expanding industry and the demand
for new cultivars. Propagation by seedage and graftage were the
two methods selected for evaluation in the research. Seed experiments
were initiated to identify optimum treatments for...
Local government officials and county planners may find descriptive information concerning the economic structure of each Oregon county useful for planning for future economic development. Specifically, citizens of counties and planning districts need to know whether industries in their area are growing or declining and in which industries a comparative...
This study centered upon two objectives. First, to demonstrate and apply a statistical method, the transfer function, and to test its usefulness in regional economic modeling and regional impact ana1ysis; and second, to obtain a better understanding of the causal relationships among total employment, government employment, lumber and wood products...
The B lymphocyte is the immune cell responsible
for the production of antibodies. It has receptor
molecules on its surface which bind to a molecule known
as an antigen. The antigen either stimulates the cell
to produce antibodies or tolerizes it so that it is
unable to produce antibodies.
It...
Methodology for characterization of the phenolic profile of
apple, pear and grape juice was developed. It utilized High
Performance Liquid Chromatography (HPLC) for separation of
individual phenolic compounds and Diode Array Detection for
recording the Ultra-violet (UV) spectrum of chromatographic
peaks. The high resolution achieved and the ability of recording...
Seven red raspberry (Rubus Ideaus L.) samples from Oregon, Washington, British Columbia and New Zealand were processed into juice. These, along with three juice samples supplied from West Germany were analyzed by high performance liquid chromatography, (HPLC), for nonvolatile acid, sugar, anthocyanin and anthocyanidin composition. In
order to quantitate the...
We discuss a mathematical model arising in the filtration of a
fluid through a porous medium. The model leads to a free boundary
value problem whose governing equation depends on the retention
function. A numerical approximation by means of finite elements
is used to present an existence and uniqueness theorem...
Our purpose is twofold, to derive a 2-dimensional model of streambed erosion and to develop a solution procedure to solve the equations of our model. The flow domain, which varies in time, is bounded above by a free surface and is bounded below by an erodable streambed. An initial flow...
An analytical model of the radiative contribution to the
total heat transfer between a large-particle (greater
than 1 mm) gas-fluidized bed and an immersed horizontal
tube is discussed. The model is applied to the case of a
bubbling bed and the emulsion phase contribution is obtained from a detailed analysis...
