The Supplemental Poverty Measure (SPM) is the newest method to paint a more accurate picture of the scope of poverty in the United States than the Official Poverty Measure (OPM). In doing so, the SPM includes many sources of income, including income from work and in-kind government supplemental policies. The...
The primary purpose of this investigation was to determine the
conditions necessary for the preparation of cell-free extracts of
nodule bacteroids capable of catalysing the reduction of acetylene to
ethylene and nitrogen to ammonia. Initial investigations were conducted
to determine whether intact soybean root nodules would reduce
acetylene to ethylene...
Climate change and other anthropogenic impacts are threatening the existence of millions of species around the globe. On western continental boundaries, the large-scale secondary process of upwelling, which brings low pH, deoxygenated, high nutrient seawater to the surface, is compounded by climate change, that together could drive some species to...
The Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor and member of the basic helix-loop-helix Per/ARNT/Sim (bHLH/PAS) family of chemosensors and developmental regulators. As a member of the PAS domain family of transcription factors responsive to exogenous signals, the AhR exerts influence on many processes relating to cellular fate....
We have developed a compact micro total analysis system (μTAS) to serve as a platform for in-situ spectrophotometric water quality monitoring. Individual fluidic, optical, and electrical components were designed, developed, and characterized. These components were combined in both an integrated (single lithographic “chip-based” platform) and a modular manner. The microfluidic...
Six polycyclic aliphatic hydrocarbons were reacted with the
trichloromethyl radical photolytically generated from bromotrichloromethane
at 40°. Relative rates of reaction were correlated
with a computer analysis of the change in strain energy in going
from the ground state to the intermediate. A good correlation between
the log of the relative...
This thesis presents the development of a supervisory controller for a pre-commercial
Brushless Doubly-Fed Machine (BDFM) drive system. In addition,
characterizations of new diecast rotors for the BDFM are presented. Using the
characterization results from the new rotors, a control scheme was developed to allow a
BDFM to be packaged...
