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...

The relationship of lysosomal stability to radiation-induced delay of cell division in Tetrahymena pyriformis

Creator:: Hodge, Frederick Allen
Abstract:: Cell division in a heat synchronized Tetrahymena pyriformis (GL-I) cell can be delayed if the cell is exposed to X-irradiation (300 kVp, 20 mA, HVL = 0. 9 mm Cu, 25 R/ sec) prior to a critical time after the end of the synchronizing treatment (EST). At the critical time,...

Automated science curriculum : an experimental science program

Creator:: Hutchinson, John Stuart
Abstract:: Purpose: The purpose of this study was to determine statistically the effects of an automated science curriculum on the science learnings of eighth grade students. This curriculum involved the use of Keysort cards as a flexible handbook for teachers and included in the directions for use a teaching method which...

A study of the deterioration of X-ray fluoroscopic screens

Creator:: Properzio, William Stuart, 1940-
Abstract:: From the time when fluoroscopic screens were first used there have been scattered references to reduction in their light output due to age, use, etc. References are scarce and usually devoid of quantitative data. A long-range program has been set up in an effort to arrive at some meaningful information....

A critical analysis of wildlife conservation in Oregon

Creator:: Rymon, Larry Maring
Abstract:: This analysis is the study of Oregon's wildlife resources from the period prior to white settlement up to the present time, including critical projections, based on present trends and expected conditions for both human and wildlife populations in the state up to the year 2010. Prior to white settlement Oregon...

The influence of ionizing radiation, photoperiod, and environmental temperature on cell proliferation in the intestinal epithelium of the rough-skinned newt (Taricha granulosa)

Creator:: Filipy, R. E.
Abstract:: Kinetics of cell division in the intestinal epithelial proliferative cells (cell nests) of the rough-skinned newt, Taricha granulosa, were studied using tritiated thymidine autoradiography and the mitotic arresting properties of colcemid. Percent labeled mitoses (PLM) curves were drawn from the autoradiographic data from two separate experiments in which the newts...

An assessment of rival British theories of biogeography, 1800-1859

Creator:: Kinch, Michael P.
Abstract:: At the beginning of the nineteenth century most theorizing British naturalists supported a Biblical account of the distribution of life which was based upon the notion that life had been dispersed from the resting place of the ark. This implied a relatively even dispersion of life about the Earth, but...

In vivo counting of americium-241 in human lungs and tracheobronchial lymph nodes

Creator:: Northcutt, Allison Ruth
Abstract:: To distinguish americium-241 in human lungs from translocated activity in the tracheobronchial lymph nodes (TBLN), two intrinsic germanium detectors were collimated with 0.3-cm lead sheeting. A tissue- equivalent phantom containing either 620 nCi (22.9 kBq) in the lungs or a 2200 nCi (81.4 kBq) TBLN point source was counted; as...

History and analysis of the creation research society

Creator:: Elliott, William E.
Abstract:: The resurgence of creationism the past few years has been led by advocates of recent-creationism. These individuals, a minority among creationists in general, argue that the entire universe was created approximately 10,000 years ago in one six-day period of time. Recent-creationists support their position by appealing to the Genesis account...
