Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...
Pheromones are chemical cues produced by organisms that affect the behavior and/or physiology of conspecifics. The orchestration of reproductive behaviors in many animals depends on the expression of sex pheromones. In insects, intraspecific variation in sex pheromone expression is commonly observed and often influences social interactions between individuals. To what...
World food markets are becoming increasingly interconnected as firms seek to sell their products not only in domestic markets but in international ones as well. Moreover, processed and high-value consumer-oriented products represent an increasing share of total agricultural exports. This growing international market may have implications for the future competitiveness...
In animals, reproductive behaviors serve to attract individuals together during the
breeding season and to coordinate the behavioral and physiological states of individuals
so that mating can successfully occur. In snakes, the various reproductive behaviors
including courtship, mating, courtship inhibition, male combat and trailing are mediated
primarily by pheromones. Pheromones...
The dynamic response of an offshore structure to measured and simulated
stochastic wave forces is investigated. The theoretical nondeterministic
analysis is performed in the frequency domain for a two-dimensional
model. The ocean wave system is assumed to be a zero mean, stationary,
ergodic Gaussian process described by a one-dimensional wave...
The effect of acetylcholine on vascular adrenergic
neuroeffector transmission was investigated. Caudal
arteries of rats were isolated and their responses to
electrical stimulation of the adrenergic nerves and/or
acetylcholine were monitored. Acetylcholine had no
effect on the basal perfusion pressure or the vascular
response to norepinephrine in arteries from non-stressed...
The 2004 Indian Ocean and 2011 Tohoku tsunami events have shown the destructive power of tsunami inundation to the constructed environment in addition to the tragic loss of life. A comparable event is expected for the Cascadia Subduction Zone (CSZ) which will impact the west coast of North America. Research...
To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...
