BACKGROUND: Advanced magnetic resonance imaging (MRI) sequences, include the apparent diffusion coefficient (ADC) and diffusion-weighted imaging (DWI), are of great benefit in assessing troublesome vertebral marrow lesion in patients presented with primar... see more

Underground coal gasification (UCG) proceeds generally in the presence of an ash layer on coal (or char) surface. The ash layer increases the mass transfer resistance of O2 to the gasification surface, which may become the limiting step of whole process. ... see more

A spectrophotometric technique for the determination of the CuSO4 soret coefficient of a CuSO4-water binary solutions system is described. A short column of solutions is placed between horizontal metal plates that are held at different temperatures. The s... see more

In the article is carried out the computation of reliability function and mean time between failures of the series connected and reserved elements without recovery for diffusion-nonmonotonic distribution of their failures. Calculations are carried out for... see more

Objective. To study the possibility of application of the diffusion-weighted images of the magnet resonance tomography (?R?) for prognostication of the chronic renal disease (CHRD) development in the patients, suffering renal-cellular cancer (RCC) after r... see more

Graphene as a type of novel additive significantly enhanced the tribological performance of blended lubricating oil. However, the dispersibility of graphene with long-term stability in lubricating oil is still a challenge. Chemical modification for graphe... see more

A two-dimensional numerical model for radon transport based on the finite difference time domain (FDTD) method have been developed. The model is governed by the radon transport equation taking into account the mechanisms of diffusion, advection, and decay... see more

Carbon monoxide (CO) gas is one of the harmful and toxic gases derived from the residue of blasting and incomplete combustion of mining equipment machines in underground mines. CO gas dilution is carried out with the intention of unsafe conditions in the ... see more

This paper is devoted to the studies of the specific features of the simulation of the particle diffusion processes in space – periodic potentials using Langevin equations. Different methods used for the presetting of initial conditions and their effect o... see more
