Calcium carbonate is a cheap and readily available filler used in rubber industry. This material is not compatible with rubber matrix, so many researchers have tried to modify its surface with various materials in order to increase its hydrophobicity and improve compatibility with the rubber matrix. In this effort, surface modification of calcium carbonate was carried out by 1.5%, 3% and 4% ste...

Recent progress in nanotechnology and electrochemical methods can be applied to fine control of the size, crystal structure, and surface properties of iron oxide nanoparticles. Here we appliedcathodic electrochemical deposition (CED) as an efficient and effective tactic for synthesisand double coating of surface of superparamagnetic iron oxide nanoparticles (SPIONs). In first step, bare Fe3O4 n...

Skidding operations can cause considerable and wide spread soil disturbance. The objective of this study was to evaluate the effects of ground skidding operations on soil compaction, moisture content, and total porosity at different levels of slope and traffic frequency. Four levels of traffic intensity (3, 8, 13, and >13 passes of a Crawler Tractor Onezhets ? 110) and three levels of slope ( ...
