 Casimir entropy is an important aspect of casimir effect and at the nanoscale is visible. In this paper, we employ the path integral method to ‎obtain a‎ ‎general‎ relation for casimir entropy and ‎i‎nternal energy of arbitrary shaped objects in the presence of two, three and four dimension scalar fields and ‎the‎ electromagnetic field. For this purpose, using Lagrangian and based on a perturb...

Background and aim: statins promote the proliferation and survival of endothelial cells. Angiogenesis is the formation of new blood vessels from pre-existing ones.It contributes to physiological and pathophysiological condition. In this research we used atorvastatin (0/1m) and (10m) with electromagnetic field on angiogenesis of chick embryo. Method: in this experiment study 98 Ross fertilized...

In this study, the efficiencies of seed priming with electromagnetic field (0, 2, 4, and 6 mT; 30 minutes daily for 3 days) were investigated in Salvia nemorosa. The exposure to electromagnetic filed led to significant increases in biomass accumulation (mean=53.6 %). Electromagnetic filed treatments significantly increased K, Ca, Mg, and Fe contents in leaves by mean 39.5 %. The electromagnetic...
