Bacterial surface layer glycoproteins

Glycobiology, 1991
Crystalline cell surface layers (S-layers) are ubiquitously present in bacterial species from almost all phylogenetic branches. Recent investigations have shown that the S-layer proteins of many archaebacteria and eubacteria contain covalently linked carbohydrate chains.

Viscosity of the ice surface layer

The Journal of Chemical Physics, 1980
The thermal contraction of ice single crystals between 0 and −50 °C has been measured by the use of silicon strain gauges frozen on the crystal basal surface. The experimental results cannot be explained without assuming the existence of a Newtonian viscous layer at the ice-strain-gauge interface; this layer has a thickness which changes in temperature

Surface waves in chiral layers

Optics Letters, 1991
We analyze the surface-wave propagation in homogeneous layers of chiral or optically active materials. Two cases of chiral slab are considered: a symmetric chiral slab waveguide and a grounded chiral slab waveguide. The dispersion relation and the electric-field components for surface waves guided in a symmetric chiral slab are analyzed and discussed ...

The Cold Surface Layer on Storglaciaren

Geografiska Annaler. Series A, Physical Geography, 1989
The thickness of the cold, water free surface layer was mapped using a high frequency radar. In the ablation area of Storglaciaren the layer was approximately 30 m thick.

Glycobiology of surface layer proteins

Biochimie, 2001
Over the last two decades, a significant change of perception has taken place regarding prokaryotic glycoproteins. For many years, protein glycosylation was assumed to be limited to eukaryotes; but now, a wealth of information on structure, function, biosynthesis and molecular biology of prokaryotic glycoproteins has accumulated, with surface layer (S ...

Layer-By-Layer Oxidation of Silicon Surfaces

MRS Proceedings, 1999
ABSTRACTLayer-by-layer oxidation of Si(111) and (001) surfaces has been studied by using scanning reflection electron microscopy (SREM). We found that SREM images reveal interfacial structures of the SiO2/Si system. Our results showed that the initial step structure of Si substrates was preserved at SiO2/Si interfaces and that interfacial steps did not

Diffusion in the diabatic surface layer

Journal of Geophysical Research, 1962
Diffusion from point and line sources in an adiabatic surface layer were briefly discussed using a similarity method by Ellison, following a suggestion made at the 1958 Oxford Symposium by Batchelor. The chief result is that the ground concentration at a downwind distance x, from a point source at ground level, is found to be proportional to xm, where ...

Temperature above the surface layer

Climatic Change, 1995
Three published data sets of upper-air global temperatures, two from radiosondes and one from satellites, are examined and compared for the lower stratosphere and troposphere.
