The incorporation of europium and dysprosium in potassium
chloride crystals was investigated. The crystals were prepared by
the Kyropoulos method from melts containing the rare-earth chlorides.
The concentration of these rare-earth ions in the crystals was determined
by neutron-activation analysis. The distribution coefficient of
europium and dysprosium between the molten...
High purity single crystals of zirconium were produced and
mechanically strained in the temperature range from 4.2°K to 293°K.
The crystals were produced by thermal treatment with a specially
constructed electron beam zone refiner which provided the abrupt
temperature gradient necessary for crystal growth. Specimens were
electrolytically machined to have...
The storage tube computer graphics terminal provides
high resolution, high speed, and comparatively low cost
graphics. Oregon State University currently supports
four such terminals under the OS-3 time sharing system.
The terminals are used for a wide variety of applications
in the physical sciences and engineering.
This thesis describes TEKPLOT...
Vegetative propagation is most effective when individuals of demonstrated superior characteristic can be propagated. For this
reason, a method for the induction of adventitious buds on cultured Douglas-fir shoot tips from 20-25 year old trees was developed. Douglas-fir shoot tips failed to survive and grow on a full strength Murashige...
The genome sequence of a baculovirus from Hemileuca sp. was determined. The genome is 140,633 kb, has a G+C content of 38.1%, and encodes 137 putative open reading frames over 50 amino acids. 126 of these ORFs showed similarity to other baculovirus genes in the database including all 37 core...
Before developing a plan or deciding to add facilities to increase tourist potential, ask the question, "Is it worth it? Will tourism do for this community what we want done?''
The cost-benefit technique balances costs against benefits to show the estimated net effects of a plan. The study may be...
In analyzing tourism, we want to know how many visitors will be coming to visit and how much they will spend, so that we can evaluate:
• Whether existing facilities can handle the visitors expected.
• Whether it will be profitable to make preparations for increased tourists.
It is important...
The money tourists spend in a community is the benefit which people probably recognize most readily. Other benefits might include improved recreation facilities, expanded cultural and social opportunities, and pride in one's community, but additional dollars provide the usual appeal for tourism development. These dollars benefit sectors throughout the community,...
Impact studies that examine the economic effects within a community of development projects such as a new hotel are usually confined to a fiscal analysis of local government costs and revenues. But increasing emphasis on the total environment-social, biological, and business-calls for an appraisal of broader impacts within the community...
