The effect of dimethyl sulfoxide (DMSO) on the radiosensitivity of the rough-skinned newt (Taricha granulosa)

Creator:: Lappenbusch, William L.
Abstract:: More than 2,000 male newts were collected during the summer and maintained unfed at 10°C both pre- and post-irradiation. Exposures ranging up to 30 kR were given with 300 kVp X-rays and ⁶⁰Co gamma rays. Half of the newts were injected (I. P.) with 15 g DMSO/kg (the maximum sublethal...

A determination and selection of a biology course content of significance for a freshman level general education course

Creator:: Hankins, Lela Ruth
Abstract:: The purposes of this investigation were twofold: 1. To determine important criteria for making a selection of course content in general biology. 2. To ascertain what should be the content emphasis in biology for the purposes of general education at the freshman college level. The literature pertinent to the problem...

Isolation and partial characterization of temperature sensitive division mutants of Chlamydomonas reinhardtii

Creator:: Wolff, Darold Melvin, 1940-
Abstract:: The primary objective of this study was to develop methods for the selection of temperature sensitive division (TSD) mutants of Chlamydomonas reinhardtii. Such methods were developed and four temperature sensitive (TS) mutants were isolated and partially characterized. Wild type (WT) cells of the plus mating type were synchronized by a...

Denison Olmsted (1791-1859), scientist, teacher, Christian : a biographical study of the connection of science with religion in antebellum America

Creator:: Schoepflin, Gary Lee
Abstract:: A biographical study of Denison Olmsted, focusing upon his own Christian world view and its connection with his various activities in science, supports the view that religion served as a significant factor in the promotion of science in America during this time period. Olmsted taught physics, meteorology and astronomy at...

Enlarging radiation survey read-outs for large audience viewing

Creator:: Aaserude, Robert Arnold
Abstract:: A method is presented for enlarging read-outs from a Victoreen Model 575 Radocon, an ionization chamber type of radiation survey instrument. The read-out enlargement is accomplished by taking the signal across the Radocon indicating meter, amplifying it, and using the amplified signal to drive a projection meter. The face and...

The GEK signatures of lowest mode internal waves

Creator:: Lipparelli, Michael Arthur
Abstract:: Present GEK (Geomagnetic Electrokinetograph) theory is extended to include internal waves of the lowest mode. The predicted towed electrode GEK signal is determined to second-order for long-crested internal waves in a finite but deep ocean. The analysis includes the determination of GEK signatures for small amplitude and finite amplitude interfacial...

Development of mitochondria-rich cells in gill epithelium of coho salmon Oncorhynchus kisutch during seawater adaptation

Creator:: Lin, David Hung Yu
Abstract:: A study on the cellular differentiation of the gill structure in juvenile coho salmon (O. kisutch) with emphasis on the excretion of monovalent ions was performed upon animals maintained under both seawater and freshwater environments. 1. The excretion rate of sodium-24 was observed to be higher for animals adapted to...

A chromatographic method for fractionating histone and ribosomal protein

Creator:: Haley, Lawrence Robert
Abstract:: Histones are presumed to be of chromosomal origin and provide both structural and functional elements for chromatin. In like manner the ribosomal proteins are of ribosomal origin and have analogous roles. Considerable controversy over their cellular roles exists because of the inability to compare directly both groups of proteins. In...

The comparative metabolism of cadmium, mercury and zinc as environmental contaminants in the freshwater mussel, Margaritifera margaritifera

Creator:: Mellinger, P. J.
Abstract:: The uptake, tissue distribution and retention patterns of cadmium, mercury and zinc were examined in the freshwater mussel, Margaritifera margaritifera. All three of these heavy metals are found in the environment. Both cadmium and mercury are toxic at low environmental concentrations. Zinc may also be toxic at low concentrations but...
