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...

Inheritance and Allelism Among the B genes in Cucurbita moschata

Creator:: Wilson, Casey K.
Abstract:: One of the most economically important genes in squash (Cucurbita spp.) is the B gene which conditions precocious depletion of chlorophyll in preanthesis fruit. The B genes are found naturally occurring in at least three of the five domesticated species of Cucurbita, including C. pepo, C. maxima and, most recently...

Development of a multi-parent advanced generation inter-cross (MAGIC) population and analysis of a nested association mapping (NAM) population for improvement of genetic resistance to white mold in snap bean

Creator:: Ağır, Ahmet R.
Abstract:: Common bean (Phaseolus vulgaris L.) comes in a huge assortment of fresh and dried varieties, including snap beans, kidney beans, and pinto beans. Together, these and other market classes provide a third of the daily dietary protein in some cultures, particularly in Africa, Asia, and developing nations in the Americas....

Breeding Snap Beans for Organic Agriculture: Quantification and Application of Key Traits

Creator:: Park, Hayley E.
Abstract:: Improving crop cultivars for use on organic farms is pertinent, as current elite germplasm is less resilient within the more variable context of organic farm environments. Although a growing number of studies have focused on organic plant breeding in cereal crops, very few have focused on vegetable crops, especially those...

Adaptive Self-governance of Small-scale Commercial Fishers in Northeast Puerto Rico: Characterizing Formal and Informal Cooperation during Times of Crises

Creator:: Gómez-Andújar, Nicolás X.
Abstract:: Small-scale fisheries often suffer from weak, formal governance, and in response they organize in various ways. These self-organizational arrangements rely on the capacity of informal institutions, such as norms and communication, in generating social cohesion among actors in the supply chain and therefore improve the likelihood of generating commonly devised...

Fisheries Connectivity Networks to Measure the Adaptive Capacity of Small-Scale Fisheries in the Baja California Peninsula, Mexico

Creator:: Nomura, Keiko
Abstract:: Small-scale fisheries around the world are increasingly facing pressures from a range of environmental, economic, and social sources. In order to sustain the societal benefits of small-scale fisheries, it is imperative to understand how fishing communities adapt to disturbances. Fishermen often catch multiple different species as an adaptation technique because...

The Cosmetic Stay-Green Trait in Snap Bean and the Event Cascade that Reduces Seed Germination and Emergence

Creator:: Cirak, Melike
Abstract:: The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...

Breeding Snap Beans for Organic Agriculture: Genomic Shifts under Different Agricultural Management Systems

Creator:: King, Ryan M.
Abstract:: Although the concept of breeding crops for organic agricultural systems has been around for decades, few studies have been reported for vegetable crops to quantify and compare how conventional and organic systems differ in their selection pressures on genotypes advancing through the breeding cycle; especially research utilizing modern sequencing capabilities....

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...

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...

Abstract:: A constant temperature anemometer, utilizing quartz coated hot film probes, was used to measure velocities from .1 to 5 cm/sec. The effects on anemometer performance due to time, reimmersion, and metallic sensor coatings were examinated by repeated calibrations of the probes. Contrary to previous published results, calibration change due to...

Histologic effects of chronic selenium deficiency in selected tissues of laboratory rats

Creator:: Sprinker, Lucas Harry
Abstract:: The selenium-responsive syndromes and the discovery of Factor 3-selenium focused attention on selenium in metabolism. Two hypotheses have been advanced to explain the metabolic effect of selenium: 1) substitution or sparing of alpha tocopherol, and 2) a primary role in metabolism. The first hypothesis is supported by Scott and Desai,...
