The cessation of testing of any nuclear explosive devices in all environments is the goal of the Comprehensive Test Ban Treaty. In order to assure compliance with such a treaty, an international monitoring system has been proposed. This system will include seismic, infrasound, hydroacoustic and radionucleide monitors located throughout the world. The goal of this system is the detection of any ...

Aspects of mathematical and physical modeling deflagration explosions emerging during atmospheric (outdoor) accidental are addressed. It has been demonstrated that when physically explosions, a stoichiometric mixture in the shape sphere or hemisphere supported by ground should be used. This allows us to research parameters blast loads for worst-case scenarios address accident using most conserv...

In an effort to obtain ground truth (GT) classifications in support of nuclear explosion monitoring for continental regions of northeastern Russia, we relocated and assigned GT classifications to 118 seismic events reported in the International Seismological Centre (ISC) supplemented with previously unavailable local data. Of the relocated events, 26 events are classified as GT10. From these ev...

Rainfall patterns and land cover are two important factors that affect the runoff generation process. To determine the surface and subsurface flows associated with different rainfall patterns on sloping Ferralsols under different land cover types, observational data related to surface and subsurface flows from 5 m × 15 m plots were collected from 2010 to 2012. The experiment was conducted to as...

Motivated by the success of kinetic theory in the description of observables in intermediate and high energy heavy ion collisions, we use kinetic theory to model the dynamics of core collapse supernovae. The specific way that we employ kinetic theory to solve the relevant transport equations allows us to explicitly model the propagation of neutrinos and a full ensemble of nuclei and treat neutr...

Crises are discontinuous changes in the size of a chaotic attractor as a parameter is varied. A special type of crisis is an explosion, in which the new points of the attractor form far from any previously recurrent points. This article summarizes new results in explosions in dimension one, and surveys previous results in dimensions two and three. Explosions can be the result of homoclinic and ...

coriander is one of the important economic plants for medicinal production. this investigation consists of the effects of different drip irrigation (surface and subsurface) and furrow irrigation methods on grain, oil and essential of coriander. for this purpose, experiment over the past two years (2010 and 2011) in a randomized complete block was designed in three replications. treatments were ...

Magnetotelluric (MT) method is an electromagnetic technique that uses the earth natural field to map the electrical resistivity changes in subsurface structures. Because of the high penetration depth of the electromagnetic fields in this method (tens of meters to tens of kilometers), the MT data is used to investigate the shallow to deep subsurface geoelectrical structures and their dimensions....

We study nucleosynthesis in ’hypernovae’, i.e., supernovae with very large explosion energies ( ∼ > 10 ergs) for both spherical and aspherical explosions. The hypernova yields compared to those of ordinary corecollapse supernovae show the following characteristics: 1) Complete Siburning takes place in more extended region, so that the mass ratio between the complete and incomplete Si burning re...
