D. Hidayat, B. Chouet, B. Voight, P. Dawson, Antonius Ratdomopurbo
2002, Geophysical Research Letters (29) 33-1-33-4
Very-long-period (VLP) pulses with period of 6–7s, displaying similar waveforms, were identified in 1998 from broadband seismographs around the summit crater. These pulses accompanied most of multiphase (MP) earthquakes, a type of long-period event locally defined at Merapi Volcano. Source mechanisms for several VLP pulses were examined by applying moment...

2002, Journal of Applied Ecology (39) 79-90
1. Animal populations, defined by geographical areas within a species’ distribution where population dynamics are largely regulated by births and deaths rather than by migration from surrounding areas, may be the correct unit for wildlife management. However, in heterogeneous landscapes varying habitat quality may yield subpopulations with distinct patterns in...
Cement manufacture and the environment - Part I: Chemistry and technology
H. G. Van Oss, A.C. Padovani
2002, Journal of Industrial Ecology (6) 89-106
Hydraulic (chiefly portland) cement is the binding agent in concrete and mortar and thus a key component of a country's construction sector. Concrete is arguably the most abundant of all manufactured solid materials. Portland cement is made primarily from finely ground clinker, which itself is composed dominantly of hydraulically active...

Model-based estimation of individual fitness
William A. Link, Evan G. Cooch, Emmanuelle Cam
2002, Journal of Applied Statistics (29) 207-224
Fitness is the currency of natural selection, a measure of the propagation rate of genotypes into future generations. Its various definitions have the common feature that they are functions of survival and fertility rates. At the individual level, the operative level for natural selection, these rates must be understood as...

Water level fluctuations in an urban pond: Climatic or anthropogenic impact?
S. E. Benton
2002, Journal of the American Water Resources Association (38) 43-54
In 1996, the Illinois State Geological Survey began an investigation of fluctuating water levels in a pond in Cary, Illinois. The cause of the fluctuations appeared to be ground water discharge into a storm sewer recently installed by the Illinois Department of Transportation. However, analysis of climatic data provided an...
A national look at water quality
Robert J. Gilliom, David K. Mueller, John S. Zogorski, Sarah J. Ryker
2002, Water Resources Impact (4) 12-14
Most water-quality problems we face today result from diffuse "nonpoint" sources of pollution from agricultural land, urban development, forest harvesting and the atmosphere (U.S. Army Corps of Engineers et al., 1999). It is difficult to quantify nonpoint sources because the contaminants they deliver vary in composition and concentrations...
