Heavy use of outdoor recreation areas in the United States
since World War II is endangering their quality. Demand made by a
rapidly growing population with rising personal incomes and increasing
leisure time is expected to grow 50 percent nationally and 146 percent in Oregon by 1975. In Oregon, population,...
This paper focuses on the explosive and controversial growth in finfish farming in general and salmon aquaculture in particular, and the response of Alaska policy makers to this emerging industry. It seeks to define and analyze why Alaska policy makers chose to prohibit all commercial culture of finfish at a...
The primary objective of this study was to identify, and to
group, the professional education competencies common to administrators
of vocational education. The technique of factor analysis was
used to form logical groups of competencies. The secondary objectives
were to:
1. determine, by the method of the analysis of variance,...
Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)-
6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)-
glycine], the naturally occurring apoplastic leaf solutes, and
the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate)
were compared. Aliquots of sap were expressed from intact
sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4
bars. Three distinct fractions were detected...
Some perennial grass seed crops such as red fescue (Festuca rubra
L.) do not produce a profitable seed crop during the first growing
season. The present establishment method in Oregon for red fescue seed
crops generally entails spring planting which does not satisfy
vernalization requirements for seed production in the...
Stable oxygen and carbon isotope δ[superscript 18]O and δ[superscript 13]C analyses of otoliths are becoming increasingly common in fisheries science and management. However, little is known about the statistical properties of isotopic data and few attempts have been made to explore appropriate statistical methods that could be used for otolith...
Greenhouse and field grown coffee plants were used to
study the synchronization of flowering and fruiting. The
purpose of these studies was to develop methods of
improving the selective harvesting of mature coffee fruits
by machine. The studies were divided into 4 parts: 1)
Synchronization of flowering, 2) Synchronization of...
Thirty-six female guinea pigs were placed on a scorbutogenic
diet for 14 days and then divided into groups of four. Three groups
received adrenocorticotropic hormone (ACTH) with each group given
10, 20, or 40 units. Three groups each received 50 mg of ascorbic
acid and three groups received 50 mg...
