ON THE ABRASIVE WEAR HIGH STRENGTH COATING LAYERS ON MACHINE PARTS TESTING
Plasma coating technology was applied to machine parts. During application, the jet formed hits the surface of the material and particles are deposited on the surface. In this way, layers of high thickness can be applied and thus revitalize worn machine parts. The paper examines the abrasion resistance of Al2O3 and Al2O3 phosphate layers applied to...

COMPARATIVE ANALYSIS OF OLD-GROWTH STANDS JANJ AND LOM USING VEGETATION INDICES
Old-growth forests represent a very valuable field for research of natural processes. The application of remote sensing was carried out on two old-growth forests in the northwestern part of the Republic of Srpska. The sample plots from OG Janj show relatively higher mean values (NDVI, SAVI and EVI) compared to OG Lom, with the exception of the VARI...
