This study aims at analytically and numerically exploring the influence of combustion-induced thermal expansion on turbulence in premixed flames. In theoretical part, contributions solenoidal potential velocity fluctuations to unclosed component advection term Reynolds-averaged Navier–Stokes equations are compared, a new criterion for assessing importance effects is introduced. The highlights r...

Neuronal progenitor cells of the anterior subventricular zone (SVZa) migrate along the rostral migratory stream (RMS) to the olfactory bulb, where they exit the cell cycle and differentiate. The molecular mechanisms that regulate SVZa progenitor proliferation and cell-cycle exit are largely undefined. We investigated the role of p27 KIP1 in regulating cell proliferation and survival in the RMS ...

Neural stem cells (NSCs) persist in the adult mammalian subventricular zone (SVZ) of the lateral ventricle. Primary NSCs generate rapidly dividing intermediate progenitor cells, which in turn generate neuroblasts that migrate along the rostral migratory stream (RMS) to the olfactory bulb (OB). Here, we have examined the role of the COUP-TFI and COUP-TFII orphan nuclear receptor transcription fa...

AIMS To define the prevalence and characteristics of non-rheumatic annular mitral stenosis (AMS) in a general population as compared with rheumatic mitral stenosis (RMS). METHODS AND RESULTS Clinical and echocardiographical variables were assessed in 70 patients with mitral stenosis. AMS and RMS patients were age- and gender-matched for the comparison of echocardiographic variables. Thirteen ...

This study quantified the interplay and gradient effects on GTV dose coverage for 3D CRT, dMLC IMRT, and VMAT SABR treatments for target amplitudes of 5-30 mm using 3DVH v3.1 software incorporating 4D Respiratory MotionSim (4D RMS) module. For clinically relevant motion periods (5 s), the interplay effect was small, with deviations in the minimum dose covering the target volume (D99%) of less t...

The influence of rotation on turbulent convection is investigated with direct numerical simulation. The classical Rayleigh-Bénard configuration is augmented with steady rotation about the vertical axis. Correspondingly, characterization of the dynamics requires both the dimensionless Rayleigh number Ra and the Taylor number Ta. With increasing Ta the root-mean-square (rms) velocityvariations ar...

The relationship between behaviour of radio wave propagation and building architecture in a small indoor environment is examined. A site is divided into three partitions on the basis of number of walls between transmitter and receiver. Wideband radio propagation measurements are performed in each partition and the data analysed to compare channel characteristics in the partitions. Comparisons i...
