In this thesis innovative tunnel devices based on new architectures, new fabrication approaches and novel material combinations are fabricated and investigated in detail. In particular, nanowire homoand heterojunction tunnel diodes based on Si and InAs-Si have been demonstrated for the rst time. The gained knowledge and understanding of tunnel diodes is applied to design and fabricate InAs-Si h...

1. We investigated the glycine-induced response in ventromedial hypothalamic (VMH) neurons freshly dissociated from 8- to 12-day-old rats using the nystatin and gramicidin perforated patch recording modes. The nystatin-formed pores in the plasma membrane are permeable for both monovalent cations and anions, whereas those formed by gramicidin are permeable only to monovalent cations. Therefore, ...

The main goal of this paper is a compactness result for families of functions in the space SBV (Special functions of Bounded Variation) defined on periodically perforated domains. Given an open and bounded set Ω ⊆ R, and an open, connected, and (−1/2, 1/2)-periodic set P ⊆ R, consider for any ε > 0 the perforated domain Ωε := Ω ∩ εP . Let (uε) ⊂ SBV (Ωε), p > 1, be such that ́ Ωε |∇uε|p dx+H(Suε...

BACKGROUND Our goals were to analyze cost and efficiency of performing carpal tunnel release (CTR) in the main operating room (OR) versus the ambulatory setting, and to document the venue of carpal tunnel surgery practices by plastic surgeons in Canada. METHOD A detailed analysis of the salaries of nonphysician personnel and materials involved in CTR performed in these settings was tabulated....

In this paper, simulation of fire in a short 2-lane road tunnel and its evacuation are described. Two traffic situations in the tunnel and their impact on people evacuation in fire conditions are analyzed. For simulation of the tunnel fire, the FDS (Fire Dynamics Simulator) system, version 5.5.3 based on advanced CFD (Computational Fluid Dynamics) fire model is used. The evacuation of people in...
