The objective of the current study was to evaluate traffic and geometric features and their influences on the safety performance of roundabouts by developing suitable crash modification factors (CMFs).The cross-sectional method can be applied as an alternative method to estimate the CMFs when before-and-after studies are impractical to apply, e.g.,
Household food consumption is the associative link between ecosystems and anthropogenic activities.In grassland areas, inappropriate food phyre vapes consumption patterns will cause irreversible damage to vulnerable local ecosystems.For this study, we selected three typical transitional grassland areas of Inner Mongolia, China (i.e., meadow steppe,
We present a theoretical study of the dynamics of a thick polar epithelium subjected to the action of both an electric and a flow field in a planar geometry.We develop a generalized continuum hydrodynamic description and describe the tissue as a two component fluid system.The cells and the interstitial hastu goyal fluid are the two components and w
