Observations and theory relevant to evaluating the importance of effect Ionosphere-Earth current density, JZ, in global electric circuit on cloud microphysics opacity at high latitudes, with presumed consequences for surface pressure, are reviewed updated. The day-to-day input variations less than 10% their mean values, as reported pressure effects, but could be indicative more important longer...

The cytotoxic activity of natural killer cells is usually tested by radioactive assay CSI Cr release assay), which detects the release of cytoplasmic contents after plasma membrane disintegration of dying cells. In contrast to this indirect evaluation of cytotoxicity, the assessment of cell damage by flow cytometry aims to provide a more exact characterization of the death pathway via detec...

Cloud computing is changing businesses and governments. It offers flexible computation resources in a model where customers only pay for resources they use. This leads to cost savings when compared to a situation where organizations manage their own server farms. Very often such servers are running at a very low utilization level, which is partly because of old habits that lead to not placing m...

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...

This second part of a two-part study examines the lightning and charge structure evolution of the 29 June 2000 tornadic supercell observed during the Severe Thunderstorm Electrification and Precipitation Study (STEPS). Data from the National Lightning Detection Network and the New Mexico Tech Lightning Mapping Array (LMA) are used to quantify the total and cloud-toground (CG) flash rates. Addit...

SUMMARY: BACKGROUND AND METHODS: As a source of hematopoietic stem cells, cord blood (CB) is an alternative to bone marrow or peripheral blood stem cells (PBSC). The Mannheim Cord Blood Bank has currently stored about 1,750 allogeneic CB units. Here we report our experiences and discuss future perspectives of CB banking. We analyzed CB units for nucleated cell (NC), mononucleated cell (MNC) and...

Abstract The current study identifies and quantifies various mechanisms of entrainment, their diluting effects, in the developing mature stages a simulated supercell thunderstorm. two stages, differentiated by lack or presence rotating updraft, are shown to entrain air different, but related that result from strong vertical wind shear environment. greatest entrainment rates stage asymmetric ove...

1It is generally recognized that the environmental buoyancy and vertical wind shear have important effect on the characteristics of convective storms. Parameters and indices, such as the bulk Richardson number (BRN) and environmental storm -relative helicity, have been commonly used in both research and operations to characterize the environmental properties important to thunderstorm developmen...
