This experiment was carried out to evaluate the potential of extracted Datura metel seed oil as a bio wood preservative against fungi attack reports have shown bio-preservatives be toxic free and environmentally friendly. The from by Soxhlet apparatus using N-Hexane ethanol solvents volume-to-volume method dilution kerosene (at 50%) added increase its quantity thereafter. phytochemical screenin...

azomethine-H methods are based on ABSTRACT photometry (1,9,33). AWPA A2-98 (1) This paper describes the development of a microsssay for boron and the application macroassay method has been used in of this microassay for evaluating leachability of boron by post-treatment of southern several studies to measure boron conpine with the calcium precipitating agent NHA (N'N-napthaloylhydroxylamine). T...

Wood in outdoor applications is exposed to various environmental factors that cause weathering. Weathering important, primarily from an aesthetic standpoint and predominantly wooden claddings. However, not all parts of claddings are equally Sections UV radiation moisture discolour faster than less sections, such as wood under roof overhangs. Architects owners seek a uniform appearance buildings...

Wood-based composite utility poles are rece!VIng increasing attention in the North American pole market. This interest is being driven by many increasing factors such as increasing: (I) disposal costs of solid wood poles, (2) liability and environmental concerns with traditional means of disposal of solid wood poles, (3) cost and concerns of long-term availability of pole-sized timber, and ( 4)...

Reliable exposure factors are essential to determine health risks posed by chemicals in consumer products. We analyzed five risk-concerned product categories (anti-fogging, dye, disinfectant, repellent, and preservative products) for 13 products (three car anti-fogging products, a lens anti-fogging product, two car dye products, two drain disinfectants, an air conditioner disinfectant, a chlori...

Description of the subject. In Europe, heat treatment native wood species is gradually becoming an industrial reality. It provides a promising alternative to both use naturally durable, essentially tropical woods and chemical preservative treatments based on biocides. Objectives. The aim this study quantify effect physico-mechanical decay resistance properties three hardwood (oak, ash, beech + ...

Nanoparticles (NPs) in aqueous suspension have just begun to be exploited for the preservative treatment of wood. However, at present, there is very little information available on the distribution of NPs in wood after impregnation, due to associated analytical challenges. In this study, we present the detection of model NPs in softwood and hardwood by surface-enhanced Raman spectroscopy (SERS)...
