wood vinegar is the aqueous phase of the liquid produced during the slow pyrolysis of wood.it has the potential to be used as a pesticide against various weeds, insects and molluscs. due to divergentfeedstocks, pyrolysis processes and storing conditions, the chemical composition of wood vinegar variesbetween producers and time. the aim of our current study was to use the copse snail arianta arb...
Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...

A recent analysis of R&D productivity suggests that there are grounds for 'cautious optimism' that the industry 'turned the corner' in 2008 and is 'on the comeback trail'. We believe that this analysis is flawed and most probably wrong. We present an alternative analysis of these same data to suggest that the industry is not yet 'out of the woods' and suggest that many of the systemic issues af...
From the still life with a bowl of fruit to scenes of wildlife in the woods, from Michelangelo’s David to Damien Hirst’s Verity, biology often provides the shapes, forms, colours and concepts that most inspire visual artists to create their own representation of life. Apart from the unique case of Leonardo da Vinci, the scientific and the artistic eye cast on living things have rarely resided i...
the influence of initial moisture content on wood decay at different levels of atmospheric oxygen concentration was studied. three fungi, coriolus versicolor (c. versicolor) a white rot, coniophora puteana (c. puteana) a brown rot, and chaetomium globosum (c. globosum) a soft rot, were chosen. the mycelia of the fungi were inoculated in to mini blocks of fagus sylvatica (beech) and pinus sy...
