This project calculates the value of β for ice particles based on wavelength dependent values of their refractive and absorptive indices. β is the ratio of the force due to radiation to the force due to gravity acting on a particle in the solar system. This parameter can later be...
Future satellite missions like NASA’s upcoming Magnetospheric Multiscale (MMS) mission are targeting reconnection diffusion regions at the Earth’s magnetopause. These diffusion regions are small compared to the total surface area of the magnetopause. Furthermore, the location of the diffusion region depends on external parameters such as the current state of...
Six standard coyote scent station index lines and one scentless control line were repeatedly sampled from May through October, 1974, on a 400 square mile study area in Central Oregon. The scent station index remained relatively constant at a mean value of 0.025 from May through mid-August; increased to a...
Oregon's minimum stream flow program is intended to protect
certain instream flow values by maintaining sufficient stream
flows to support aquatic life and to minimize pollution. The
increasing demand for consumptive uses of water, as well as certain
deficiencies in the laws, policies, and administration of the program,
bring into...
The "old-growth controversy" in the Pacific Northwest recognized thinning as the
primary silvicultural practice for land managers to produce wildlife habitat while
continuing to produce timber. For the foreseeable future, forest stands will be harvested to
produce forest gaps and a patchwork of trees of different ages. In order to...
The analysis of a member carrying a combination of lateral and axial
loads (a "beam-column") is a problem of frequent occurrence in aircraft
structural design. This thesis presents the derivation and application
of the Polar method, both analytical and graphical. The method was first
suggested in Germany, several years later...
Lipids, especially phospholipids, are very common
but important molecules found in cells and animal
tissue, performing many biological functions, particularly
in membranes. Lipids, when mixed with water,
spontaneously form ordered systems, such as micelles,
vesicles and multibilayers. The size of these systems
and their degree of ordering depend on the...
