Aims. We assess the evolutionary status of the intriguing object Walker 90 (V590 Mon, LkHα 25, NGC 2264-Vas62, HBC 219, IRAS 06379+0950, 2MASS J06404464+0948021), which is located about 20 arcminutes northwest of the Cone Nebula near the center of the open cluster NGC 2264. This object, according to its most recent spectral type determination (B7), which we confirmed, is at least 3 magnitudes t...

The antimicrobial activity of essential oils of oregano, thyme, basil, marjoram, lemongrass, ginger, and clove was investigated in vitro by agar dilution method and minimal inhibitory concentration (MIC) determination against Gram-positive (Staphylococcus aureus and Listeria monocytogenes) and Gram-negative strains (Escherichia coli and Salmonella Enteritidis). MIC(90%) values were tested again...

Type V collagen inhibits the cell-substratum adhesion of many types of cells. In this study, inhibitory effects of type V collagen on the adhesion of mouse melanoma B16-F10 cells to fibronectin, laminin and vitronectin were investigated. When the culture dishes were coated with a mixture of fibronectin and type V collagen, adhesion of the cells was inhibited by 50% at a fibronectin/collagen mol...

A quantum mechanical model is developed for the observed resonance enhancement of light scattering by aggregates of electronically interacting chromophores. Aggregate size, monomer oscillator strength, extent of electronic coupling, and aggregate geometry are all important determinants of intensity in resonance light scattering (RLS) spectra. The theory also predicts the value of the depolariza...

In dieser Ausarbeitung stellen wir die Probleme One-Slot-Scheduling und Scheduling im Modell SINRG vor. Dieses Modell ist physikalisch motiviert und geht davon aus, dass Sensorknoten in der euklidischen Ebene verteilt sind. Sendende Sensorknoten üben Interferenz aufeinander aus. Bei den beiden genannten Problemen geht es darum, gewünschte Funkverbindungen so zu planen, dass die dabei auftretend...

This work presents an optimized method for the determination of multiple samples containing 90Sr when its daughter 90Y is measured after chemical separation and in sequence, i.e. during its decay. Consequently the measurement times will increase for each subsequent sample, since there has been a longer time for decay before measurement. Compared to a previously published approach, when 90Y is m...
