the goal is assessing the diffusion magnetic resonance imaging (dmri) method effi ciency in characterizing focal hepatic lesions (fhls). about 28-fhl patients were studied in radiology and clinical imaging department of our university hospital using 1.5 tesla mri system between january 2010 and june 2011. patients underwent hepatic mri consisting of dynamic t1- and t2-weighted imaging. the dmri...

As we have seen in previous chapters (Chapter 4 by Callaghan, and Chapter 5 by Le Bihan), nuclear magnetic resonance (NMR) is the gold standard for measuring the diffusivity of water and other spin-labeled species. It is the least perturbing measurement imaginable, providing extremely accurate and precise data. We have also learned that the subsequent combination of the Stejskal and Tanner puls...

The paper presents data on the dynamics of body weight and mass coeffi cient lungs in golden Syrian hamsters after infection with SARS CoV-2 virus. It was found that most pronounced deviations studied parameters develop 7th day disease. study also demonstrates main histopathological changes during this period

Electrochemical characteristic parameters such as diffusional permeability, ion transport number, fi xed charge concentration and electrical resistance for a regenerated cellulose/polypropylene-supported membrane (RC/PP sample) in contact with NaCl solutions at different concentrations were determined. The effect of the polypropylene support on mass and charge transport was estimated by compari...

In dynamic regression models conditional maximum likelihood (least-squares) coeffi cient and variance estimators are biased. From expansions of the coeffi cient variance and its estimator we obtain an approximation to the bias in variance estimation and a bias corrected variance estimator, for both the standard and a bias corrected coeffi cient estimator. These enable a comparison of their mean...

Radon (222Rn) is a naturally occurring radioactive gas that originates from the decay of radium (226Ra) in the primordial uranium (238U) decay series. As a noble gas, it easily migrates through inter-granular spaces; then, because of advection, diffusion and convection with other gasses or with water, it moves through fi ssures and faults until it reaches the outdoor atmosphere. Its half-life i...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(2): 497–502. The paper is focused on a hydraulic problem of water overfall on hydrotechnic structures, especially outlets and spillways of water reservoirs. The main parameter o...

The Article deals with the controlled influence of adhesive force in contact road vehicle’s wheel road. first section shows how is reduced. next step familiarization experimental vehicle Alternative SkidCar, where measurements were carried out, assessment advantages and disadvantages SkidCar drive on sliding surface following test methods. objective article to determine great difference b...

Comprehensive analysis of the chemical phenomena taking place in the liquid metal/gaseous phase systems typical for metallurgy requires knowledge of the mass transfer phenomena occurring in both the said phases. This results from the fact that in heterogeneous systems, the components of the individual phases react with one another only after penetrating the interface. The parameter characterisi...

A blind box economy has emerged in 2019, reflecting new consumption psy-chology among the young Z generation. Based on previous studies Customer Perceived Value (CPV), customer satisfaction, and loyalty, this study analyzes 12 characteristics, 5 CPV, loyalty via questionnaires interviews. Better-Worse Coeffi-cient analysis, characteristic, Kano attribute classification of CPV are used to determ...
