Spatial differentiation of gully clusters based on the regional scale: an example from northeastern China [PDF]

PeerJ, 2020
Gully erosion represents a serious environmental threat around the world, but their spatial distribution law are unclear at the regional scale. To quantitatively characterize the spatial distribution model of gullies and determine the regularity of ...

Hydrogen sulphide alleviates iron deficiency by promoting iron availability and plant hormone levels in Glycine max seedlings

BMC Plant Biology, 2020
Background Hydrogen sulphide (H2S) is involved in regulating physiological processes in plants. We investigated how H2S ameliorates iron (Fe) deficiency in soybean (Glycine max L.) seedlings.

Clinical Studies of Dental Erosion and Erosive Wear [PDF]

Caries Research, 2011
We define <i>erosion </i>as apartial demineralisation of enamel or dentine by intrinsic or extrinsic acidsand <i>erosive tooth wear</i> as the accelerated loss of dental hard tissue through the combined effect of erosion and mechanical wear (abrasion and attrition) on the tooth surface.
