One of the areas wood waste processing is their use in production wood-polymer composites (WPC). The relevance products due to wide range applications and qualities this material. WPC does not rot, damaged by insects fungi, contain harmful binders. Products from duodenum do crack, gouge, are waterproof, which makes them an excellent material for manufacturing a terrace board. However, board mus...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
application of cellulosic fibers and minerals of deinked waste paper sludge has a great impression on utilization and characteristics of final product. this study was designed to produce use gypsum-fiber board from the dip sludge. the gypsum: sludge ratio was considered as 100:0, 90:10, 80:20, 70:30 and 60:40. two types of gypsum boards were prepared with fixed 12 mm thickness and cold pressing...

Observations from the WHISPER (Waves of High frequency and Sounder for Probing of Electron density by Relaxation) instrument on board Cluster, for the interval spanning 2001–2012, are utilized to determine an empirical model describing the total electron density along closed geomagnetic field lines. The model, representing field lines in the region of 4.5≤ L<9.5, includes dependences on L and m...
