The relativistic plane-wave Born approximation is applied to the study of inelastic collisions charged particles with atoms, by considering atomic wave functions calculated from independent-electron self-consistent Dirac-Hartree-Fock-Slater potential. A database longitudinal and transverse generalized oscillator strengths (GOSs) has been computed using accurate numerical methods for all subshel...

Distributed computing enables parallel execution of smaller tasks that make up a large job. Its purpose is to reduce the job completion time. However, random fluctuations in task service times lead straggling with long times. Redundancy provides diversity allows when only subset redundant executed, thus removing dependency on tasks. Under constrained resources (here, fixed number ...

An algorithm for the derivation of LET-distributions from pulse-height spectra obtained with proportional counters is described. The method is based on Fourier transformation; it is applicable to spherical as well as non-spherical proportional counters. The relation between the energy mean, E,, of LET and the energy mean, g , , of the lineal energy density is given. 1. Introduction Tissue equiv...

The book written by seventeen experts in the field of rangeland management, this compilation of essays brings to light the latent issues concerning this subject to readers all over the globe. Though technical approaches can address some issues, social processes ultimately prevent the balancing of these matters. Socio-economic and political institutions are often a stumbling block for improving ...

the aim of this study was to investigate the range utilization of rhode island red hens, grazing outdoor (under tropical conditions) and to scan their activities inside the house as well as during their outdoor visits. the activities of rir hens, raised in indoor floor pens connected with outdoor areas covered with natural vegetation, were scanned and recorded individually within 15 minute inte...
