Integracija toplotnih pumpi u postojeći energetski sistem u malim i srednjim preduzećima

open access: yesEnergija, Ekonomija, Ekologija, 2022
Industry processes are characterized by large amounts of energy losses dissipated as waste heat to the ambient. In industry sectors analysed in the US, China and EU28 low- temperature waste heat below 230ºC makes up from 33% up to 60% of waste heat.

Transcriptomic analysis of grape (Vitis vinifera L.) leaves during and after recovery from heat stress

open access: yesBMC Plant Biology, 2012
Background Grapes are a major fruit crop around the world. Heat stress can significantly reduce grape yield and quality. Changes at the molecular level in response to heat stress and subsequent recovery are poorly understood.
