Abstract. Mesoscale convective systems (MCSs) are especially visible in the summertime when there is an advection of warm maritime air from west. Advection masses enriched by water vapour, source which can be found over Mediterranean Sea. In propitious atmospheric conditions, and thus significant convection, instability or strong vertical thermal gradient leads to development thunderstorm syste...
Abstract. The representation of unresolved clouds in radiation schemes coarse-resolution weather and climate models has progressed noticeably over the past years. Nevertheless, a lot room remains for improvement, as current picture is by no means complete. main objective present study to advance cloud–radiation interaction parameterization, focusing on issues related model misrepresentation clo...
We have investigated the characteristics of human hematopoietic progenitor cells (HPCs) with the CD34(+)CD45(low)SSC(low) phenotype from full-term placental tissue (FTPT) as compared to cord blood (CB) and fetal liver (FL) cells. We demonstrated the presence of cell subpopulations at various stages of the differentiation with such immunophenotypes as CD34(+/low)CD45(low/-), CD34(++)CD45(low/-),...
This study assessed the incidence of cytomegalovirus (CMV) infection after transplantation of cord blood (CB) from unrelated donors and evaluated strategies for screening CB donors. Posttransplantation CMV infection, reported in 23% of 1221 CB recipients, was associated with patient pretransplantation CMV serology (P < .001), but not with CMV serology in CB donors or their mothers. A total of 2...
We present measured radio emission from cosmic-ray-induced air showers under thunderstorm conditions. We observe for these events large differences in intensity, linear polarization and circular polarization from the events measured under fair-weather conditions. This can be explained by the effects of atmospheric electric fields in thunderclouds. Therefore, measuring the intensity and polariza...
Purpose Pathologic complete response to neoadjuvant chemoradiation therapy (CRT) is associated with improved outcomes for patients with locally advanced rectal cancer (LARC). Increased response rates have been reported with higher radiation doses, but these studies often lack long-term outcome and/or toxicity data. We conducted a case-control analysis of patients with LARC who underwent definit...
the supercapacitive behavior of polyaniline/mno2-carbon black (pani/mno2-cb), mno2-cb nanocompositesand cb was studied. mno2-cb made by the in situ direct coating method to deposit mno2 onto cb; then pani coating was coated on it. morphology of the nanocomposite was studied by x-ray diffraction (xrd), fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the el...
The importance of narrow zones of boundary layer convergence (or boundaries) for thunderstorm development and evolution has been recognized since the days of the Thunderstorm Project. Boundary detection and characterization are primary objectives of automated nowcasting systems, which employ surface data, radar and satellite observations of current storms and trends in their intensity to foreca...
Cord blood (CB) is a valuable donor source in hematopoietic cell transplantation. However, the initial time to engraftment in CB transplantation (CBT) is often delayed because of low graft cell numbers. This limits the use of CB. To overcome this cell dose barrier, we modeled an insufficient dose CBT setting in lethally irradiated mice and then added hematopoietic stem/progenitor cells (HSCs/HP...
