This investigation was motivated by the apparent increase in genetic
variability resulting from the systematic combining of gene pools
represented by winter and spring types of wheats.
It was the objective of this study to provide information regarding
the nature of this genetic variability for nine agronomic characters
in populations...
This thesis examines the transient and steady-state temperature performance
of a rotary regenerative heat exchanger. In contrast to previous
studies on this problem, fluid flow in the circumferential direction was
considered. Appropriate modeling was included to measure the effect of
carry-over on the differential equations describing mass and energy
conservation....
In November 1990, Oregon voters approved Ballot Measure 5,
placing an ultimate ceiling on local property tax rates of 1.5% of
market value (excluding specific levies for capital expenditure). Any
resulting shortfalls in local education revenues are to be made up by
transfers from state funds, at the expense of...
By 1976 extended fisheries jurisdiction had been
declared by most coastal states and territories of the
world. The new regime of property rights was expected to
affect seafood production costs which, in turn, could impact
on seafood trade and the competitive positions of
producing countries. In theory this policy should...
Effective two-body interactions were obtained from
realistic nucleon-nucleon potentials and applications made
in calculations of ground state properties of even-even N=Z light nuclei. The admixture of high momentum states into
the nuclear wavefunction caused by the strong, short-range
repulsion of the two-nucleon force was taken into account
by making a...
The development of a novel high temperature space radiator is
described. A Rotating Bubble Membrane Radiator (RBMR) combines the
best features of heat pipes and droplet radiators while avoiding
their negative attributes. The RBMR offers light weight, self
deployment, ease of startup and its performance is less affected by
acceleration....
Sediments on the inner portion of the Oregon continental shelf
consist of clean, well-sorted, detrital sand. This sand has an average
median diameter of 2.53Φ (. 173 mm) and is both positively and
negatively skewed. Deposits with median diameters in the coarse
sand and gravel classes occur at depths of...
Respiratory infections caused by nontuberculous mycobacteria (NTM), especially Mycobacterium avium, can lead to progressive, recurrent disease that is refractory to therapy. Bacterial biofilms are intrinsically resistant to a variety of stressors and pressures, including host killing mechanisms and antibiotic therapy. Though it is becoming increasingly evident that NTM biofilms are...
Breast cancer is the leading cancer in women with an estimated 13% of women in the United States developing a form of invasive breast cancer in her lifetime. The survival rate is estimated to be 85%, but the American Cancer Society estimates that early detection of breast cancer in the...
