b values and ω−γ seismic source models: Implications for tectonic stress variations along active crustal fault zones and the estimation of high-frequency strong ground motion b values and ω−γ seismic source models: Implications for tectonic stress variations along active crustal fault zones and the estimation of high-frequency strong ground motion
In this study the tectonic stress along active crustal fault zones is taken to be of the form , where is the average tectonic stress at depth y and Δσp(x, y) is a seismologically observable, essentially random function of both fault plane coordinates; the stress differences arising in the course of crustal faulting are derived from Δσp(x, y). Empirically known frequency of occurrence...

Better utilization of ground water in the Piedmont and mountain region of the southeast Better utilization of ground water in the Piedmont and mountain region of the southeast
The development of water supplies for domestic consumption, and for those commercial and industrial uses requiring relatively pure water, has followed a pattern in the Piedmont and mountain areas of the southeast similar to that in most other humid areas. The first settlers utilized seepage springs on hillsides. Such springs occur along steep slopes where the water table intersects the...

Modeling of rock friction 1. Experimental results and constitutive equations Modeling of rock friction 1. Experimental results and constitutive equations
Direct shear experiments on ground surfaces of a granodiorite from Raymond, California, at normal stresses of ??6 MPa demonstrate that competing time, displacement, and velocity effects control rock friction. It is proposed that the strength of the population of points of contacts between sliding surfaces determines frictional strength and that the population of contacts changes...

Modeling of rock friction 2. Simulation of preseismic slip Modeling of rock friction 2. Simulation of preseismic slip
The constitutive relations developed in the companion paper are used to model detailed observations of preseismic slip and the onset of unstable slip in biaxial laboratory experiments. The simulations employ a deterministic plane strain finite element model to represent the interactions both within the sliding blocks and between the blocks and the loading apparatus. Both experiments and

Multiple-factor influences upon feeding flight rates at wading bird colonies (Alias: Are flight-line counts useful?) Multiple-factor influences upon feeding flight rates at wading bird colonies (Alias: Are flight-line counts useful?)
The temporal patterns of feeding, resting, and reproductive behavior in colonial wading birds have been studied by a number of investigators (Recher and Recher 1972, King 1974, Capen 1978, Custer and Osborn 1978, Kushlan 1978) both on a short-term (daily) and long-term (annual) basis. In coastal marine environments, activities at colonies are influenced by tides (Recher and Recher 1972...

Recovery of breeding success in a population of brown pelicans Recovery of breeding success in a population of brown pelicans
Breeding populations of the brown pelican (Pelecanus occidentalis) declined during the 1960's on both east and west coasts of the United States. In 1969, colonies in South Carolina fledged an average of 0.78 young per nest (Blus et al. 1974b), and those in California only 0.004 (Anderson et al. 1975). The minimum production for population stability has been estimated to be 1.0 to 1.2...
