Float fraction of float/sink process of car shredder light fraction was received from RAV (The Netherlands) in the frame of the W2Plastics (http://www.w2plastics.eu/) EU7 project (magnetic sorting and ultrasound sensor technologies for production of high purity secondary polyolefins from waste). The differently coloured plastic waste particles were manually separated and after determining the m...

Enzymatic hydrolysis of cellulose in plant and wood cell walls is expected to be affected by its chemical composition as well as structural and morphological features. In the present study, different crystallinity cellulose samples and varying size fractionated loblolly pine wood cell wall particles were hydrolyzed using a mixture of Celluclast and Novozyme 188. In pure cellulose samples of Wha...

[1] Individual aerosol particles collected over southern Africa during the SAFARI 2000 field study were studied using transmission electron microscopy and field-emission scanning electron microscopy. The sizes, shapes, compositions, mixing states, surface coatings, and relative abundances of aerosol particles from biomass burning, in boundary layer hazes, and in the free troposphere were compar...

The impact of wood combustion on ambient aerosols was investigated in Augsburg, Germany during a winter measurement campaign of a six-week period. Special attention was paid to the high time resolution observations of wood combustion with different mass spectrometric methods. Here we present and compare the results from an Aerodyne aerosol mass spectrometer (AMS) and gas chromatographic – mass ...

Homer and Wigley (1936) reported a case of dermatitis due to Mansonia wood (Sterculiacea altissima) and in his annual report the Chief Inspector of Factories (1936) also reported that the dust of this wood could give rise to serious symptoms and in this respect compared it with African box wood. There are apparently no other reports of the possible dangers relating to the use of this wood, and,...

The anti-skid resistance of six coatings (Alfa, Beta, Gamma, Lambda, Mu and Theta) designed for outdoor wood flooring were tested in chestnut (Castanea sativa Mill.) and pine (Pinus pinaster Ait.) using a Portable Skid Resistance Tester according to standard ENV 12633. Film thickness, coating retention level, and presence of mineral particles were determined for each coating. Furthermore, the l...

The density of humic acids and humic like substances (HULIS) from fresh and aged wood burning and pollution aerosol particles E. Dinar, T. F. Mentel, and Y. Rudich Department of Environmental Sciences, Weizmann Institute of Science, Rehovot 76100, Israel Institute for Tropospheric Chemistry, Research Center Jülich, Jülich, Germany Received: 25 July 2006 – Accepted: 7 August 2006 – Published: 11...

The objective of this research was to characterize the qualities (mechanical properties and water resistance) of particleboard made from saline Jose Tall Wheatgrass (JTW), Agropyron elongatum. For the JTW particleboards made with 4% polymeric methane diphenyl diisocyanate (PMDI), the mechanical properties and water resistance improved with the increase of particleboard density from 0.71 to 0.75...

in this research, the effect of tension wood formation in populus nigra on its anatomical characteristics was studied. vessel element and ray frequency (n/mm²), vessel diameter and ray dimensions were measured in both normal and tension wood. furthermore, the formation of gelatinous layer (g-layer) in the fibers of tension wood was studied. the results showed that the vessel proportion and diam...

The simultaneous pyrolysis of coal with wood was experimentally found to allow reducing concentrations sulfur-containing substances in gases released. objective experimental studies is comparison the sulphate calcium and aluminum ash coal-wood mixtures after latter a dense “packing” aggregate particles these two fuels at few millimeters distance between particles. 3B-grade lignite, T-grade bitu...
