Polar analysis of beam-columns for aircraft

Creator:: Jones, Walter Richard
Abstract:: 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...

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: 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...

Investigating the Genetic Control of Fusarium Root Rot Resistance in Snap Beans

Creator:: Huster, Abigail R.
Abstract:: Root rot diseases are a major constraint to bean (Phaseolus vulgaris L.) production around the world. Both snap beans and dry beans are affected. Root rot diseases can be caused by a variety of pathogens; however, Fusarium solani is a common causal agent. Fusarium root rot is a primary yield...

Rogue pod traits in Phaseolus vulgaris

Creator:: Al-Bader, Noor
Abstract:: Snap beans are the vegetable form of dry bean (Phaseolus vulgaris L.) with low fiber, stringless and round, succulent pods that are eaten in the immature stage. Seed companies commit significant resources to maintaining purity and uniformity of snap bean cultivars. While some variability may be introduced through outcrossing (beans...

The study of active sites and bubble formation frequency in nucleate boiling heat transfer

Creator:: Aoki, Tadao
Abstract:: The heat-transfer mechanism studied in this experiment was pool boiling from a flat horizontal surface facing upward with the bulk liquid at its saturation temperature. The hot-film anemometer probe was introduced to boiling heat-transfer analysis as a possible device for counting active nucleation sites and for other investigations such as...

An investigation into the mechanisms of adherence between borosilicate glass and steatite ceramic and between borosilicate glass and alumina ceramic

Creator:: Peck, Roger Lee
Abstract:: A qualitative evaluation was made of the adherence between borosilicate glass and the ceramics, steatite and alumina. Three basic adherence studies were performed. (1) A comparison between the x-ray diffraction patterns of the ceramic and the fused glass-ceramic powder mixture was made to determine if any new compounds were formed...

The effect of entrance configuration on local heat transfer coefficients in subsonic diffusers

Creator:: Stoffel, Edward Oswald
Abstract:: The effects of round, square, and reentrant entrances on flow regimes and local heat transfer coefficients were determined using a symmetrical, plane-wall two-dimensional, subsonic air diffuser with one of the diverging walls heated and maintained isothermal. Flow and heat transfer studies were made at total divergence angles ranging from 0...

The design, construction and calibration of an instrumented surface for convective heat transfer studies

Creator:: Meyers, Stanley Kent
Abstract:: The purpose of this thesis work has been the design, construction and calibration of an instrumented surface for convective heat transfer studies. The surface is in the form of a flat plate roughly 24 inches wide by 48 inches long. It is made up of 48 individual cells, laminated side-by-side...

An experimental study of natural convection in air between a vertical isothermal flat plate and a parallel insulted flat plate

Creator:: Lee, Soon Mo
Abstract:: The free convective heat transfer phenomena in air between two vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the other adiabatic. A quartz fiber anomometer was used for measuring local velocities in the air between the vertical...

Some aspects of an hemophilus infection in the laboratory rat

Creator:: Burdett, Ramsay George
Abstract:: There is need for more knowledge of the naturally acquired diseases of the laboratory rat. Respiratory diseases occurring in the species were reviewed with special reference to an acute respiratory disease affecting certain rats in the Oregon State University closed Wistar rat colony which has also involved human infections. The...
