The katabatic wind system over the Greenland ice sheet is studied using simulations of the hydrostatic Norwegian Limited Area Model (NORLAM) and measurements of an instrumented aircraft. The structure and the dynamics of the katabatic wind over the ice sheet are investigated for a case study of the aircraft-based experiment KABEG (Katabatic wind and boundary layer front experiment around Greenl...

Bare copper sheet and three commercial Cu-based alloys, Cu15Zn, Cu4Sn and Cu5Al5Zn, have been exposed to four test sites in Brest, France, with strongly varying chloride deposition rates. The corrosion rates of all four materials decrease continuously with distance from the coast, i.e. with decreasing chloride load, and in the following order: Cu4Sn>Cu sheet>Cu15Zn>Cu5Al5Zn. The patina on all m...

We investigate experimentally the behavior of a thin sheet of polytetrafluoroethylene between a steel plate and a cylindrical steel indenter under combined action of high normal force and torsion. Under these actions, the polytetrafluoroethylene layer is partially squeezed out of the contact area. The thickness of the remaining layer is studied as function of the applied normal force, the torsi...

BACKGROUND Split- thickness skin graft is one of the most common operations in plastic surgery. It is always painful and patient discomfort from donor site often is more significant than recipient site. There is not still a standard method for treatment of the donor site. The purpose of this study was to determine the best method of dressing the donor site among three different methods with re...

Disposable hygienic products are classified as technical textile and used intensively in the field of medical textiles. As a product, sanitary napkin consists top sheet, an inner layer (Acquisition Distribution Layer (ADL) core Pulp/Superabsorbent mixture), back sheet. Nonwovens commonly production these components. The most important factors to consider new product design rapid absorption mens...

The surface layer protein encoding genes from five mosquito-pathogenic Bacillus sphaericus isolates were amplified and sequenced. Negative staining of the S-layer protein extracted from the cell wall of wild-type B. sphaericus C3-41 was prepared. It showed a flat-sheet crystal lattice structure. Two genes encoding the entire and N-terminally truncated S-layer protein (slpC and DeltaslpC respect...

Resonantly damped surface type quasi-modes are computed as eigenmodes of the linear dissipative MHD equations for a simple equilibrium model of a current sheet. The current sheet is modeled by a nonuniform plasma layer embedded in a uniform plasma environment. The physical equilibrium variables change in a continuous way in the nonuniform plasma layer. In particular, this is the case with both ...
