We analyzed the frequency and regional distribution of cells with genetic abnormalities of chromosomes 1, 14, and 22 in meningiomas. This data was evaluated for correlation to the clinical outcome of the patients. Eight defined areas of each of 77 paraffin-embedded meningioma samples (59 grade I, 13 grade II, and 5 grade III) were analyzed by fluorescent in situ hybridization using bacterial ar...

The consistency of the constraint with the evolution equations for spatially inhomogeneous and irrotational silent (SIIS) models of Petrov type I, demands that the former are preserved along the timelike congruence represented by the velocity of the dust fluid, leading to new non-trivial constraints. This fact has been used to conjecture that the resulting models correspond to the spatially hom...

This paper presents and analyzes two different strategies of heterogeneous distribution of computations solving dense linear algebra problems on heterogeneous networks of computers. The first strategy is based on heterogeneous distribution of processes over processors and homogeneous block cyclic distribution of data over the processes. The second is based on homogeneous distribution of process...

characteristics of precipitation and the regionalization major role in the efficient use of water resources and soil and management of environmental hazards. regionalization of rainfall can help to better use of water resources and to correct manage of environmental hazards. according to the analysis of climate phenomena such as precipitation, all data should be related to a homogeneous region,...

A capillary chromatography system has been developed based on the tube radial distribution of the carrier solvents using an open capillary tube and a water-acetonitrile-ethyl acetate mixture carrier solution. This tube radial distribution chromatography (TRDC) system works under laminar flow conditions. In this study, a phase diagram for the ternary mixture carrier solvents of water, acetonitri...
