Root rot diseases of bean (Phaseolus vulgaris L.) are a problem wherever they are grown, and are a major constraint to dry edible and snap bean production. Root rot is a primary yield limitation of snap bean production in the US, especially within the top three snap bean producing states...
The advanced backcross-quatitative trait loci (AB-QTL) breeding method was employed on snap bean (OR 91G x PI433251B) and dry bean (M0162 x PI433251B) interspecific populations to transfer resistance QTL from resistant donor parent Phaseolus coccineus into P. vulgaris. For OR 91G x PI433251B, analyses produced nine linkage groups corresponding to...

White mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, results in severe losses in the production of common bean, Phaseolus vulgaris, especially snap bean varieties. Advanced backcross QTL analysis was used to identify quantitative trait loci for resistance to white mold in an interspecific cross of P. vulgaris and P....

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...

Small-scale fisheries often suffer from weak, formal governance
The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...
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...
Riparian areas are an integral component of fluvial ecosystems. The management of Oregon's riparian areas has come under greater scrutiny since that latest revision of the Oregon Forest Practices Act (1994). Many riparian areas lie within forested areas. Riparian management issues such as anadromous fish population decline and large woody...
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...
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...
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...
