An attempt was made to differentiate between runs of steelhead by comparing the reassociations of their DNA. Conditions for the reassociation were studied using E. coli DNA, and observations
were made spectrophotometrically. Of the five buffers examined, 1.0 molar sodium perchlorate plus one-hundredth molar tris-HCl, pH 7.1, at 60° or...
The genome composition and DNA base sequence homologies
of several diverse species of fish were examined. The fishes were
characterized from spectrophotometric studies of reassociation and
hybridization of their DNAs and from the thermal stabilities of hybrid
duplexes.
Spectrophotometric studies indicated that repeated sequences
comprise 35-40% of the genomes of...
1. Genetic tools are commonly used for conservation and management of at-risk species. Individuals are often sampled from mixtures that are composed of many populations, which creates a need to assign individuals to their source. This can be problematic when the genetic divergence among source populations is weak but can...
The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...
The fishing communities in the St. Anthony area of Newfoundland, Canada, were forced to adjust to the
collapse of cod catches in Atlantic Canada in the early 1990’s. It was not only the fishing industry that
was affected. The entire community had to live through the changes in resources. To...
A distinguishing feature of elite cross-country (xc) skiers is their superlative upper body power (UBP). Race points/rankings are highly correlated to UBP, thus it appears that UIBP training is an integral component to the success of xc ski racers. Recently, roller board training was shown to be superior for improving...
Running economy (RE) is the amount of oxygen utilized (ml.kg⁻¹min⁻¹) when
running a fixed speed, and it has been demonstrated to be an important factor
determining race performance in distance runners. There is evidence that running
economy and/or maximal oxygen consumption (VO₂max) improves over the course
of a training season...
Endurance athletes set the intensities of training sessions using blood lactate data from a maximal graded exercise test. Specifically, these intensities are set as a percentage of heart rate (HR) at lactate threshold (LT). Often, however, gas exchange threshold (GET) data is used as a predictor of LT as it...
