This study was conducted to investigate the relationship between
the Human Development Program (HDP) and reading achievement and
between HDP and the self-concept of selected fourth grade students
attending a public school. A further purpose was to investigate the
relationship between fourth grade students' measured feelings of
responsibility for the...
There is increasing evidence that the type of land cover surrounding remnant patches of native habitats (the ‘matrix’) can modify effects of landscape change on biodiversity; thus the traditional idea of dichotomous habitat and non-habitat following island biogeography theory is insufficient in complex landscapes. Matrix type can have dramatic influences...
We present a deterministic spectral method to predict equilibrium temperature distributions, heat flux, and thermal conductivity in homogeneous and heterogeneous media. We solve the Boltzmann transport equation in a second order spatial, self-adjoint angular flux formulation. We implemented this method into the radiation transport code Rattlesnake, built using the MOOSE...
Downward flow opposing mixed convection conditions have been studied using the FLUENT CFD code. This work was comprised of two primary objectives. The first was to study core channel flow reversal susceptibility in the Gas Reactor Test Section (GRTS) at low flow conditions. The second objective was the development of...
The Boltzmann transport equation derived in the Self-Adjoint Angular Flux (SAAF) formulation is applied to simulate phonon transport. The neutron transport code Rattlesnake is leveraged in this fashion, slightly modi ed to accept input from variables consistent with phonon transport simulations. Several benchmark problems are modeled to assess the potential...
The Generation IV Very High Temperature Reactor (VHTR) design is being actively
studied in various countries for application due to its inherent passive safe design,
higher thermal efficiencies, and proposed capability of providing high temperature
process heat. The pebble bed core is one of two core designs used in gas...
The Endangered Species Act (ESA) grants legal standing for any individual or party willing to challenge a species status finding in court. As a result, the legislation has become a controversial, but powerful tool leveraged in political battles and legal disputes that go far beyond the narrow confines of conservation...
