Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...

to evaluate the nutritive value in some lignocellulosic materials, 3 sets of experiments were conducted on aspen, and grape woods. to enhance the digestibility, the woods were treated with 5% naoh. throughout the first trial, chemical composition and digestibility coefficients of dry matter, organic matter and ndf of experimental feeds, ph of rumen, as well as palatability were evaluated while ...

the entomopathogenic fungus metarhizium anisopliae (metschnikoff) sorokin, causal agent of green muscardine of insects, is an important fungus in biological control of pests. no reports exist on the impact of this fungus on microcerotermes diversus silvestri (iso.: termitidae) in the world. the present research evaluated efficacy of strain demi001, from saravan, iran, against m. diversus. the t...

As part of the process outlined in Washington's Statewide Strategy to Recover Salmon: Extinction is Not an Option the Washington Departments of Fish and Wildlife, Ecology, and Transportation were charged to develop Aquatic Habitat Guidelines employing an integrated approach to marine, freshwater, and riparian habitat protection and restoration. Guidelines will be issued, as funding allows, in a...

the current research was planned to investigate the effect of maleic anhydride (man) and glycidyl methacrylate (gma) treatments on morphological and physical properties of the hornbeam wood-styrene composite. test samples were divided according to astm d4446-05 to control and treated with man, st, man/st and man /st/gma. treatment was performed by vacuum- pressure method using a experimental cy...

The present studies were conducted on effect of plant extracts on Trametes versicolor (White rot) fungal colonization and inhibition of treated and untreated wood of Pinus roxburghii Sargent. The data on colonization and fungal inhibition were noticed significant variation. Among the concentrations, maximum value for fungal colonization treated wood samples with extract was noticed in the (100%...

High-Density Polyethylene (HDPE)-based composites with alkaline copper quaternary (ACQ)and micronized copper quaternary (MCQ)treated wood fibers were manufactured through injection molding. The mechanical properties, water absorption, and biological resistance properties of the fabricated composites with different coupling treatments were investigated. Composites with ACQand MCQ-treated wood ha...

influences of temperature as well as holding time on physical and mechanical properties of fir wood were studied in this work during the oleothermal wood modification. wood samples were cut and treated oleothermally in the soybean oil at 200 and 230°c for the holding time of 1, 3 and 5 hours. weights and the dimensions were measured before and after treatment. bending strengths, water absorptio...
