There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
Juvenile Chinook Salmon (Oncorhynchus tshawytscha) leave the natal reach at different times and move downstream at different rates which can increase their productivity by allowing them to utilize habitats on different temporal scales and spreading risk of localized stochastic events. This life history diversity can also allow fish to adapt...
Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...
Poet John Haines is best known for his first book of
poetry, Winter News, which was published in 1966. The book
contains poems about the Alaskan landscape that surrounded
Haines during his many years of living in Richardson,
Alaska. The recurring motifs in his poems include hunting,
trapping, the Arctic...
The search for the stand density that optimizes growth and hence generates the maximum amount of wood is one of the philosopher’s stone in modern forestry. Since scientific methods were applied to forestry, numerous generations of foresters have studied the relations between stocking density and growth, obtaining diverse results and...
Electrophoretic karyotypes were obtained from intact cells of four wild
type strains of Tilletia caries and T. controversa, and 5 inter specific hybrid
progeny using clamped homogeneous electric field, pulsed field gel
electrophoresis (CHEF PFGE). Each karyotype was polymorphic and unique
relative to the other strains. However, the relative size...
A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
This thesis traces the relationship between the First World War, constructions of masculinity, and the life and poetry of T.S. Eliot. Central to this relationship is a study of homoeroticism, which the author characterizes as different from homosexuality but not exclusive of it, in late 19th and early 20th century...
