Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...

Subglacial erosion and sediment dynamics influence the size, stability, and climatic sensitivity of large ice sheets. These processes may regulate large-scale surging behavior, initiating rapid shifts in climate and sea level (MacAyeal, 1993a,b), and perhaps dictate the periodicity of the Quaternary ice ages (Clark and Pollard, 1998). We intuitivly associate the scoured landscapes of the northe...

This review investigates erosion and abrasion in dental structures undergoing at- home bleaching. Dental erosion is a multifactorial condition that may be idiopathic or caused by a known acid source. Some bleaching agents have a pH lower than the critical level, which can cause changes in the enamel mineral content. Investigations have shown that at-home tooth bleaching with low concentrations ...

Abstract Arctic coastal erosion damages infrastructure, threatens communities and releases organic carbon from permafrost. However, the magnitude, timing sensitivity of increase to global warming remain unknown. Here we project Arctic-mean rate very likely exceed its historical range variability before end century in a wide emission scenarios. The roughly doubles, reaching 0.4–0.8 m yr −1 °C 2....

MPSIAC is currently known as an appropriate method to measure sediment ofWatershed basins of the country while there has not been any sensitivity analysis so far forthis method. In this study, required data for MPSIAC model were gathered from six basins;Amame-Kamarkhani, Kand-Golandok, Tang Kenesht (from two different references), Nojian(from three different references), Pegahe sorkh katvand (f...

Land degradation by soil erosion is one of the most severe environmental issues that greatly dependent on land use management. In this study, effects long-term management (including annual cultivated field (ACF), fallow (FF), rangeland (R), and orchard (OF)), depth (0–10 10–20 cm), organic matter content (SOM) wind- water-erosion indices were investigated in calcareous soils southern Iran. Soil...

BACKGROUND/AIMS Professional wine tasters face a hidden occupational hazard due to the high acid content in wine. This study evaluates the self-perceived dentinal sensitivity and erosive effects of wine on the professional wine tasters of the Granite Belt and the Scenic Rim regions of South East Queensland, Australia. METHODS Seventy wineries were contacted and participants were surveyed abou...
