Interspecific hybridization between Phaseolus vulgaris and P.
coccineus results in the formation of either mature F₁ seeds or abnormal
embryos, depending on the direction of the cross. However, normal as
well as abnormal embryos occur in the reciprocal F₂ populations. The
exact cause of abnormal embryo development is unknown. To...
Power planning efforts in Oregon require accurate information
about hydroelectric potential. Potential uses for Geographic Information
Systems (GISs) are being investigated by three Oregon planning agencies.
This paper presents a method in which a 616 is used to help identify and
reduce uncertainty in previous hydroelectric inventories. Uncertainty with
respect...
Dungeness crab is an important fishery on the Pacific Coast.
The processing subsystem of the fishery is hampered by a variety of
problems that have acted to impede technological innovations that
could improve efficiency and sanitation in seafood plants. This paper
provides background for problems encountered by the processors, discusses...
It is no longer possible in any area of the United States to formulate
water resources plans for single purpose projects as has been
done in past years. No longer can one of our greatest natural resources,
water, be used solely for navigation, power generation,
irrigation, or controlled for reducing...
Perennial ryegrass (PRG, Lolium perenne) is a hardy cool-season grass that is infected with the endophytic fungus Neotyphodium lolii, which enables the plant to be insect repellant and drought resistant, lowering the use of insecticides and fertilizers. However, this fungus produces the compound lolitrem B (LB, m/z 686.4) which causes...
For the last fifty years, meadow foxtail (Alopecurus pratensis L.) has been invading native flood meadows throughout the Harney Basin in southeastern Oregon. The expansion of this grass species has been the result of its broad climatic requirements and ability to withstand drought while thriving in saturated soil conditions for...
Alpha acids are found in the lupulin glands of hops cones. These acids have no bitterness of their own, but can be isomerized and subsequently hydrogenated to form bitter iso-α-acids and tetrahydroiso-α-acids respectively. Current literature values for the detection thresholds of iso-α-acid and tetrahydroiso-α-acid in lager beer have been reported...
