In this study is to examine the effect of industrial heat treatment application on dimensional stability and dynamic wettability properties ash (Fraxinus excelsior) wood. Ash samples that were treated for 120 minutes at 210 degrees according ThermoWood process used. study, a total 30 samples, including 15 with dimensions 20x20x30 mm, unheat cut examined. The results obtained in showed property ...

The evolution of laws on the use of biocide products has led to important changes in the field of wood preservation leading to an increasing interest for non “biocidal treatments” like thermal or chemical modifications. While thermal modifications become more and more common on industrial scale, development of chemical modifications progresses slowly. One reason for the challenges encountered i...

The influence of physical and chemical properties of 20 species of imported wood on degradation of the wood by termites under field conditions was studied. The wood species studied were: Sycamore maple, Acer pseudoplatanus L. (Sapindales: Sapindaceae) (from two countries), Camphor, Dryobalanops aromatic C.F.Gaertner (Malvales: Dipterocarpaceae), Beech, Fagus grandifolia Ehrhart (Fagales: Fagace...

A quantitative evaluation of wood chemical components for some tree species in a forest area from east-northern Romania is presented here, through a comparative study from 1964 to 2000. Investigation upon the wood tree-rings in a Quercus robur L. tree species, as a dominant species, as regards its chemical composition and structure of the natural polymer constituents cellulose and lignin was al...

Pigment disorders1,3 Hypopigmentation or depigmentation. Lesions demonstrate increased sharpness of borders under Wood lamp examination and fluoresce bright blue-white owing to the increased amount of dermal collagen illuminated. This results from decreased or absent intervening melanin. Vitiligo: patches, varying in location and extent. Tuberous sclerosis: patches; characteristic shapes are la...

Buxus wallichiana Baill, belongs to family Buxaceae. Traditionally Buxus wallichiana is used as bittertonic, diaphoretic, anti-rheumatic, vermifuge, antihelmentic, analgesic, purgative, diuretic, antiepileptic, antileprotic and in hemorrhoids. Th is paper deals with the macroscopic, microscopic and powdered studies of Buxus wallichiana wood, along with this physical constants like ash values an...

Overview Description of real life problem Motivation for choosing a multiple objective model Multiple objective model (decision variables, objectives, constraints) Technique used to solve the problem Analysis of results Opinion about the proposed model and solution approach Description of the real life problem We consider a waste incineration plant Input : Waste (cardboard, wood, glass, food wa...

This paper reviews the use of charcoal and wood ash in acid soils as adsorbents to improve N availability at same time improving their soil fertility crop productivity. Soil acidification poses a major challenge agricultural sustainability it is serious highly weathered such Ultisols Oxisols which are noted for nutrient deficiency Al Fe ions toxicities. Understanding sorption mechanisms isother...

this study was aimed to investigate the effect of altitude on fiber characteristics, chemical composition and kraft yield pulp of brutian pine. wood samples were collected from different altitudes as 450, 750 and 960m of arabdagh plantation, located in kalaleh region in the northeast of golestan province. three healthy sample trees of brutian pine were cut from each altitude. maceration of earl...

ABSTRACT The addition of wood ash to soil is an alternative disposing this residue. However, the effects on physical-hydric properties remain divergent. In study, added water characteristic curve, gravitational water, field capacity, total available and saturated hydraulic conductivity were evaluated in Oxisol (40% clay texture) Quartzipsamment (6% sand texture). experimental design was complet...
