We studied the ligand-induced endocytosis of the yeast alpha-factor receptor Ste2p by immuno-electron microscopy. We observed and quantitated time-dependent loss of Ste2p from the plasma membrane of cells exposed to alpha-factor. This ligand-induced internalization of Ste2p was blocked in the well-characterized endocytosis-deficient mutant sac6Delta. We(More)

N.I. Vavilov considered the territory of Afghanistan, the site of one of the first centers of farming, to be Central Asia’s hub of crop origin and diversity. This center also includes the hexaploid 42-chromosomal wheat with the AABBDD genomic formula. The agricultural regions of Afghanistan were surveyed repeatedly by scientific expeditions from various(More)
The wake vortex warning system, WVWS, at Frankfurt airport, in particular the so called glide-path extension is now technically completed. The system shall enable a reduction of the wake turbulence separation using predictions of the wake vortices' motion between the two closely spaced parallel final approach paths for runways 25L and 25R up to 5000 ft(More)
Basic problems of the semiclassical microscopic modelling of strongly interacting systems are discussed within the framework of Quantum Molecular Dynamics (QMD). This model allows to study the influence of several types of nucleonic interactions on a large variety of observables and phenomena occurring in heavy ion collisions at relativistic energies. It is(More)
