We have developed a cepstral simulation and inversion algorithm for analysis of regional seismic recordings of underwater explosions that determines the yield and depth of the explosions. The spectra of seismic recordings of the underwater blasts have strong time-independent spectral scalloping produced by the correlated bubble pulses and echoes of acoustic reflections from the water surface an...

This study was designed to calibrate and evaluate the subsurface drain flow component of the Root Zone Water Quality Model (RZWQM; Version 2.5) for four tillage-systems: chisel plow (CP), moldboard plow (MB), no-tillage (NT), and ridge-tillage (RT). Measured subsurface drain flow data for 1990 was used for model calibration. Main parameters calibrated were lateral saturated hydraulic conductivi...

We demonstrate the important role of anisotropic neutrino radiation on the mechanism of core-collapse supernova explosions. Through a new parameter study with a fixed radiation field of neutrinos, we show that prolate explosions caused by globally anisotropic neutrino radiation is the most effective mechanism of increasing the explosion energy when the total neutrino luminosity is given. This i...

We present a study of exploding soliton and front solutions of the complex cubic–quintic Ginzburg–Landau (CGLE) equation. We show that exploding fronts occur in a region of the parameter space close to that where exploding solitons exist. Explosions occur when eigenvalues in the linear stability analysis for the ground-state stationary solitons have positive real parts. We also study transition...

INTRODUCTION Over a period of 40 years (1949 to 1989) more than 400 nuclear explosions were carried out at the Semipalatinsk Nuclear Test Site (STS) which is located in the north-eastern part of the Kazakh Republic. According to the Kazakh Scientific Institute for Radiation Medicine and Ecology, 26 surface and 92 atmospheric nuclear explosions were carried out from August 1949 to December 1962 ...

Twenty-eight polychlorinated biphenyl (PCB) accidents were recorded during a 1-year period in Finland. They comprised leaks, fires or explosions of capacitors. Some of the explosions and fires gave rise to high concentrations of PCBs in air and of PCBs and tetrachlorodibenzofurans (TCDFs), including 2,3,7,8-TCDF, on surfaces. One large explosion is described in detail, and biomedical data and f...
