Predicting Generator Coupling Using Power System Impedance Matrices
(2008-09-09)
The combination of power flows on multiple lines constitutes a flowgate. Transmission flowgates are one tool being used to deal with wide-area stability issues because experience with dynamic simulation suggests that ...
An Accurate CMOS Four-Quadrant Analog Multiplier
(2008-09-09)
Analog multipliers are used in communication circuits, neural networks as well as frequency doublers, RMS circuits and phase detectors. High linearity is the prime issue for multipliers in conventional applications like ...
Modeling a Fuel Cell System for Residential Dwellings
(2008-09-09)
Fuel cells produce electricity by combining hydrogen and oxygen to form water. Fuel cells have unique electrical characteristics and performances that warrant examination and discussion. From the hydrogen source to the ...
Evolution of Signal Divergence and Behavior in Cyprinella galactura, the whitetail shiner
(2008-09-09)
Acoustic signaling in anurans, insects, birds, and mammals has played an important role as an interspecific isolating mechanism and is also believed to be a mechanism of sexual selection in intraspecific mate choice. A ...
A Comparative Study of the Immunological Properties of Extracellular Products Between Virulent and Less Virulent Edwardsiella tarda
(2008-09-09)
The immunological properties of the extracellular products (ECP) of the Edwardsiella tarda parent FL6-60 and mutant RET-04 isolates were investigated in Nile tilapia Oreochromis niloticus. Non-purified ECP derived from ...
Effects of hydrologic variation on dynamics of channel catfish and flathead catfish populations in regulated and unregulated rivers in the southeast USA
(2008-09-09)
Altered flow regimes resulting from dam construction can have negative impacts on growth and recruitment of fishes in regulated river systems. The effects of hydrologic variation on channel catfish Ictalurus punctatus and ...
Assessing Soil Microbial Populations and Activity Following the Use of Microbial Inoculants: Effects on Disease Suppressiveness and Soil Health
(2008-09-09)
In recent years, assessing use of microbial inoculants for promotion of plant growth has increased. Optimizing application frequency of PGPR is critical to achieving the maximum benefit from this technology. The study ...
Language acquisition of same-sex, multiple-birth siblings: A nature/nurture study
(2008-09-09)
This retrospective study considers the extent to which nature and nurture influence early first language acquisition. Data sets that address rate of grammatical acquisition, acquisition of regional dialect features, and ...
Oligotrophication Effects Following Diversion of Waste Effluent from an Embayment of Lake Martin, Alabama
(2008-09-09)
I examined the effects of nutrient diversion on water quality, phytoplankton, and macroinvertebrate and fish community structures over a 10-year period in Lake Martin, Alabama. In 2001, a pipeline began diverting treated ...
An Evaluation of the Catfish Fishery in Wilson Reservoir, Alabama
(2008-09-09)
On Lake Wilson, Alabama, a popular recreational and commercial catfish fishery exists and this study was initiated to assess population metrics and estimate exploitation. Currently, creel or length limits are not used to ...
