—MIMO satellite links have recently attracted a high interest with respect to possible link capacity enhancements. In [1] it has been shown that especially in Line-of-Sight (LOS) satellite channels maximum multiplexing gain can be achieved via the construction of orthogonal channels by means of the geometrical arrangement of the ground terminal antennae in(More)
The numbers of the carbohydrate side chains have been analyzed on a series of subtype 7 hemagglutinins of influenza A virus. The procedure employed involves growth of the virus in the presence of the trimming inhibitor N-methyl-1-desoxynojirimycin followed by controlled removal of the resulting mannose-rich oligosaccharides with endo-N-acetylglucosaminidase(More)

Semliki Forest Virus (SFV) infected chick embryo cells (CEC) incubated in the presence of Tunicamycin, a drug which specifically inhibits glycosylation, were studied under the electron microscope. No extracellular virions were produced although intracellular viral nucleocapsids in paracrystalline form were detected. Under these conditions the structures,(More)
The α-glucosidase inhibitor bromoconduritol inhibits the formation of the N-linked, complex-type oligosaccharides of the glycoproteins from influenza viruses (fowl plague virus, influenza virus PR-8) and from sindbis virus. Viral glycoproteins produced in bromoconduritol-treated chickenembryo and baby-hamster kidney cells are fully glycosylated, but(More)
—The impact of atmospheric impairments on the bandwidth efficiency of Multiple-Input Multiple-Output (MIMO) geostationary satellite links is investigated theoretically. In particular we analyze the impairments caused by precipitation because especially rain and wet snow are the most severe atmospheric impact factors degrading the channel capacity. We focus(More)

Sphingolipids are key components of eukaryotic plasma membranes that are involved in many functions, including the formation signal transduction complexes. In addition, these lipid species and their catabolites function as secondary signalling molecules in, amongst other processes, apoptosis. The biosynthetic pathway for the formation of sphingolipid is(More)
