Angiogenesis is vital for tumour formation, development and metastasis. Recent reports show that carbon nanomaterials inhibit various angiogenic signalling pathways and, therefore, can be potentially used in anti-angiogenic therapy. In the present study, we compared the effect of different carbon nanomaterials on blood vessel development. Diamond nanoparticles, graphite nanoparticles, graphene ...

In the paper, we gave after a brief overview of free space, Bacon and CEPT SE21 propagation models, mentioned in the TETRA Direct Mode Operation (DMO) standard, the comparison of the path losses, calculated by two-ray and multi-wall models and pass losses, obtained by field measurement campaign. We found out, that the tworay model is suitable for fast estimation of the TETRA DMO signal coverage...

Abstract In order to investigate the effects of nano silver and multi wall carbon nanotube levels on ‎some morphological and physiological traits of faba bean the present study was done. This ‎factorial experiment was conducted in a completely randomized design with three replications ‎and two treatments with four concentrations (0,100,200 and 300 mgl-1). The results showed ‎the total number o...

Wind tunnel experiments were performed to investigate turbulent flow over an array of heterogeneous roughness elements using stereoscopic particle image velocimetry. Nine streamwise planes, covering one periodic cell a multi-scale element that is arranged in staggered pattern, are combined quantify mean features and Reynolds stresses. Dispersive stresses, arising from spatial variations the tem...
