An autoradiographic study of cell renewal in a freshwater mussel, Margaritifera margaritifera, using high specific activity tritiated thymidine

Creator:: Tomasovic, Stephen Peter
Abstract:: High specific activity tritiated thymidine (40-60 Ci/mM) and autoradiographic techniques were used to study cell renewal systems in the freshwater mussel, Margaritifera margaritifera. Groups of mussels were injected with tritiated thymidine (1.0 [μ Ci/g) and then serially sacrificed. Tissues from selected areas of the body were routinely processed, and slides...

Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

The development of the chlorinity-salinity concept in oceanography

Creator:: Wallace, William J.
Abstract:: This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...

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...

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...

The antibiotic discovery era (1940-1960) : vancomycin as an example of the era

Creator:: McGraw, Donald J.
Abstract:: An examination of the technical and historical literature concerning the discovery and development of antibiotics suggests the possible existence of an era of discovery. This era appears to have a well-defined beginning (about 1940) and a well-defined close (about 1960). It is the purpose of this dissertation to examine the...

The population dynamics and reproductive strategy of the stream snail Oxytrema silicula (Gould) in relation to stream order

Creator:: Diamond, J. (Jerome), 1951-
Abstract:: The population dynamics and reproductive strategies of the stream snail Oxytrema silicula were examined in four coastal streams in Oregon representing a small first order stream, a wider third order stream and a fourth and sixth order stream. Samples were taken in each type of stream bottom for each stream...

J.H. Woodger and the emergence of supra-empirical orders of discussion in early twentieth century biology

Creator:: Allen, Marshall William
Abstract:: This investigation attempts to demonstrate that the development of the early 20th century biological enterprise involved a striving for a unifying theoretical perspective. A skeletal substantiation of this is given by an overview of early 20th century biology in which some biologists began recognizing a multiplicity of different orders of...

The coloration of animals : a nineteenth century controversy

Creator:: Blaisdell, Muriel Louise
Abstract:: Mimicry, obscure colors, and secondary sexual colors were important classes of observations that were analyzed by nineteenth century biologists from several vantage points. Adherents of the doctrine of special creation of fixed species believed animal colors to be evidence of design; Darwin and Wallace and their successors suggested that a...

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...
