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 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...

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...

A classification of determinants whose evaluations have appeared in periodical literature

Creator:: Liebetrau, Albert M.
Abstract:: This paper is a classification of 181 problems, each of which involves the evaluation or application of determinants. The problems are those which have appeared in the "Problems and Solutions" sections of the American Mathematical Monthly, Deutsche Mathematiker-Vereinigung Jahresbricht, Mathematics Magazine, and School Science and Mathematics. The problems are classified,...

Design of a digital repetitive titrator

Creator:: Wendlick, Joseph David
Abstract:: An automatic digital titrator for use in potentiometric titrations is described. The automatic titrator described provides a permanent digital and analog record of all titrations. The modular units which combine to form the automatic titrator are described individually. Accuracy achieved by the titrator on successive acid-base titrations of ammonia in...

The study of fluo-tantalum species by solvent extraction

Creator:: Coker, Marjory Carol
Abstract:: The extraction of tantalum fluoride complexes by large cationic extractants (tetraphenylarsonium ion, TPA, and crystal violet) and by methyl isobutyl ketone (MIBK) has been investigated as a function of fluoride concentration using ¹⁸² Ta as tracer. Extractions by the cationic extractants into chloroform were carried out in the absence of...

Studies of electrode processes with voltage scanning coulometry

Creator:: Sandoz, Dennis Paul
Abstract:: Voltage scanning coulometry was used to study the effects of electrode surfaces and metals on the electrochemistry of the ferric-ferrous couple and the silver ion-silver metal couple. The analytical technique called voltage scanning coulometry is very similar to controlled potential coulometry. The main difference is that in voltage scanning coulometry...
