Spatial variability of air dry bulb temperature and black globe humidity index in a broiler house during the heating phase [PDF]

open access: yesEngenharia Agrícola, 2013
The air dry-bulb temperature (t db),as well as the black globe humidity index (BGHI), exert great influence on the development of broiler chickens during their heating phase. Therefore, the aim of this study was to analyze the structure and the magnitude

Spatial analysis of tree regeneration in a preserved area in Zagros forests, Iran [PDF]

open access: yesEnvironmental Resources Research, 2021
Forest ecosystems are complex dynamical systems described by attributes of composition, structure, and function. To understand and manage forest ecosystems, we are required to explain and classify their dynamic structure and spatial patterns.
