The decay of ⁶¹Cu and ⁵⁹Cu--energy levels of ⁶¹Ni and ⁵⁹Ni

Creator:: Walker, Donald Arthur
Abstract:: The decay of ⁶¹Cu and ⁵⁹Cu produced by (d, n) reactions on natural nickel has been investigated. Gamma-ray energies and relative intensities were measured with a high resolution Ge(Li) spectrometer. The gamma-gamma coincidence spectrum of ⁶¹Cu was studied with a Ge(Li)-NaI(T1) system. From these data decay schemes of ⁶¹Cu and...

The utilization of nonliving algal products by larval oysters

Creator:: DeBoer, James Arthur
Abstract:: Although studies have shown that some marine invertebrates can obtain a portion of their nutrition from dissolved and nonliving particulate organic matter, the relative importance of such foods in their diet has not been established. The success of oyster hatcheries could be significantly improved if the diet of living algal...

The analysis and recommended design of a high-resolution digital data acquisition system for the in situ measurement of various physical and chemical parameters of sea water

Creator:: Albin, Arthur Grayson
Abstract:: The lack of availability of a single, complete paper on the analysis of a digital data acquisition system for in situ oceanographic measurements brought about the present work. In order to compile an accurate technical paper on such a complex system, it was necessary to design, construct, and calibrate a...

Growth of Aphanizomenon flos-aquae in defined media

Creator:: O'Flaherty, Larrance Michael Arthur, 1941-
Abstract:: A strain of Aphanizomenon flos-aquae Born. et Flah. has been introduced into culture and maintained since August of 1964 in completely defined media. It exhibits the planktonic, colonial flake form found in nature, and both heterocysts and akinetes are present. The color and size of the flake and general appearance...

Cryogenic preservation of ram spermatozoa

Creator:: Burkhart, Harry Ray
Abstract:: Investigations with ram semen were conducted to develop procedures of cyrogenic preservation that would provide long-term retention of fertilizing capacity in ram spermatozoa. An isotonic extender consisting of egg yolk, sodium citrate, lactose, glycerol, and a broad spectrum antibiotic was selected from among several extenders tested in pilot studies. Using...

A comparison between educable mentally retarded and normal students, using selected social and environmental variables

Creator:: Bates, Ralph Carson
Abstract:: The purpose of this study was to investigate the relationship between poverty and mental retardation and to place mental retardation in its true perspective as a social condition which thrives especially in poverty areas. More specifically, this study attempted to determine if there was any significant relationship between selected social...

Influence of certain chemicals on the sensitivity of rat embryos to X-irradiation

Creator:: Loawhakasetr, Pathom
Abstract:: The effect of 2-aminoethyl-2-thiopseudourea[superscript .]Br[superscript .]HBr (AET), 2-mercaptoethylamine[superscript .]HC1 (MEA) and trisodium calcium chelate of diethylenetriaminepentaacetic acid (CaNa₃DTPA) on the radiosensitivity of rat fetus was investigated. A total of 1256 fetuses were critically examined. Exposure of rats to 200 r whole-body X-irradiation at 9.5 days of gestation resulted in a...

Oregon's Mid-Willamette Valley wetlands : agricultural uses, alternative uses, problems and trends

Creator:: Tsutsui, Setsuo Harry
Abstract:: The wetlands are distinguished from other lands of the Mid-Willamette Valley by excessive soil moisture. The wetlands, as defined for this study, consist of 20 soil series (in 22 soil mapping units) which are classified by the Soil Conservation Service as having excessive wetness as the major factor limiting their...
