Vibrio cholerae has adapted to a wide range of salinity, pH and osmotic conditions, enabling it to survive passage through the host and persist in the environment. Among the many proteins responsible for bacterial survival under these diverse conditions, we have identified Vc-NhaP1 as a K+(Na+)/H+ antiporter essential for V....
Compression perpendicular to grain (C┴) of wood is an important property and has a drastic effect on serviceability of the structure. Typical C┴ loading scenarios include the bottom chord of a truss resting on the top plate of a shear wall and chords of a shear wall resting on the...
Uptake, in-plant transport, and local accumulation of organic
chemicals by plants are influenced by plant characteristics, properties
of the chemical and the soil, and by environmental conditions. Evaluations
of plant contamination required by regulatory agencies cannot be
made experimentally for the many thousands of xenobiotic chemicals in
existence or being...
The objective of this study was to investigate the effects of a flaxseed-supplemented diet on archaeal abundance and gene
expression of methanogens in the rumen of dairy cows. In all, 11 non-lactating dairy cows were randomly divided into two
groups: group A (five cows) and B (six cows). The two...
“Perennial ryegrass staggers” is a neurological condition characterized by muscular tremors and ataxia in livestock that ingest the indole diterpene lolitrem B from endophyte-infected perennial ryegrass. While the neurotoxic mechanism of action of ryegrass staggers has been defined, little is known about metabolic and other molecular processes that lolitrem B...
Reducing the weight and decreasing pressure losses of aviation gas turbine engines improves the thrust-to-weight ratio and improves efficiency. In ultra-compact combustors (UCC), engine length is reduced and pressure losses are decreased by merging a combustor with adjacent components using a systems engineering approach. High-pressure turbine inlet vanes can be...
To evaluate the impact of hypoxia (< 2 mg O₂ l⁻¹) on habitat quality of pelagic prey fishes in the northern Gulf of Mexico, we used a spatially explicit, bioenergetics-based growth rate potential (GRP) model to develop indices of habitat quality. Our focus was on the pelagic bay anchovy Anchoa...
The most diverse marine ecosystems, coral reefs, depend upon a functional symbiosis between a cnidarian animal host (the coral) and intracellular photosynthetic dinoflagellate algae. The molecular and cellular mechanisms underlying this endosymbiosis are not well understood, in part because of the difficulties of experimental work with corals. The small sea...
