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...

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...

Institutionalizing Science in Oregon : The Role of the Oregon State Academy of Sciences, 1905-1914

Creator:: Read, Richard Thomas
Abstract:: In February 1905 the Oregon State Academy of Sciences formed in Portland to promote scientific research and diffusion of scientific knowledge in Oregon. The founders also planned to assist in the discovery and development of the state's natural resources. The Academy was the first scientific society in Oregon with professional...

Benthic macroinvertebrates and sediment characteristics of a coastal dune margin lake (Carter Lake, Douglas County, Oregon)

Creator:: Wones, Andrew G.
Abstract:: Carter Lake, a freshwater, coastal dune-margin lake, was sampled at the beginning and end of the summer of 1986 to determine the sediment characteristics and benthic macroinvertebrate abundance, biomass, variety, and diversity. The distributions of major benthic habitats were estimated by snorkeling in June and July, 1986. Water temperature and...

The effects of tritiated seawater on development of the goose barnacle Pollicipes polymerus

Creator:: Abbott, David Thomas
Abstract:: The purpose of this study was to determine the effects of tritiated seawater (HTO) on selected developmental stages of the goose barnacle, Pollicipes polymerus. Barnacle embryos were cultured in Millipore cytology monitors with HTO concentrations of 0, 10⁻⁵, 10⁻³, 10⁻¹, and 10¹ μCi/ml. After 22 days, hatching was complete and...

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....

Ionizing radiation and its chemical effects : a historical study of chemical dosimetry (1902-1962)

Creator:: Chorzempa, Mary André, Sister
Abstract:: Chemical dosimetry developed in response to needs created by developments in the field of high-energy radiation. Shortly after the discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious effects of ionizing radiation were recognized. To guard against the injurious effects of radiation in medical application, dose-measuring methods...
