Spatial and temporal changes of outdoor thermal stress: influence of urban land cover types

Scientific Reports, 2022
Green infrastructure (GI) has emerged as a feasible strategy for promoting adaptive capacities of cities to climate change by alleviating urban heat island (UHI) and thus heat stress for humans. However, GI can also intensify the winter cold stress.

Size-structure dynamics of mixed versus pure forest stands

Forest Systems, 2014
Mixed species forests are presently on the advance and widely held to provide many ecosystem functions and services better than pure stands. Recent studies well explored species mixing effects at the individual tree or stand level.

PDCA – Hogyan tanul a szervezet?

International Journal of Engineering and Management Sciences, 2016
Egy szervezet (legyen az profitközpontú vagy versenyszférán kívüli) tudja, hova akar eljutni (jövőkép). Ez történhet szándék szerint megvalósult stratégia mentén, de lehet fokozatosan kifejlődő stratégia eredménye is. A stratégia vagy korábban kialakult
