erosion is considered as a main problem for the loss of arable land around the world. as the world arable land is reaching its limit, marginal areas, such as those prone to wind erosion, have gained importance for agricultural use. a simple and effective way of restoring wind eroded soils is addition of organic materials. sewage sludge can be an effective way to solve this problem. the effect o...

The article presents the main results of substantiating materials used when conducting experimental studies channel processes in a river, which is composed easily eroded soils. It substantiated that Amudarya sand cannot be modeled on geometric scale since model deposits are too small (powder) and lose property loose bodies. In such cases, material with decrease specific gravity without diameter...

all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...

A surgical sponge left in the peritoneal cavity at cesarean section eroded into the bowel and caused obstruction 3 years later. This unusual case is presented.

OBJECTIVE Toothbrush abrasion is significant in the development of tooth wear, particularly when combined with erosion. This in vitro study aimed to evaluate the impact of toothpaste slurry abrasivity and toothbrush filament stiffness on abrasion of eroded enamel. MATERIAL AND METHODS Eroded enamel samples (hydrochloric acid, pH: 2.6, 15 s) were brushed with 40 strokes in an automatic brushin...

Oil spills and natural oil seeps are sources of petrogenic hydrocarbons in soils sediments. To determine the source hydrocarbon contamination environment geochemical signature contaminant needs to be characterised. Here, we present biomarker other molecular marker diagnostic ratios Alberta Sands using gas chromatography-mass spectrometry characterise deposits detect their incorporation surficia...
