Basic density of the wood and bark of seven eucalyptus species (E. saligna, E. grandis, E. urophylla, E. camaldulensis, E. citriodora, E. paniculata and E. pellita) and three eucalyptus clones (E. grandis x E. urophylla hybrids) were evaluated before and during the cultivation of ...
[Demonstration of non-metallic foreign bodies by conventional x-ray techniques and computer tomography. Absorption coefficient of glass, plastic and wood (... Densitometric measurements were carried out on various types of glass, plastic and wood in order to determine the scope of computer tomography...

This method was first introduced to the field of wood analysis by Polge in 1963, and was further developed by various researchers. During the past two decades direct scanning X-ray densitometry systems have been developed, at which the attenuation of an X-ray beam passing through the wood ...
In the three species, the number of proventitious shoots decreased over time, favoring natural pruning. Basic density of the wood had values similar to adult plantations, which benefited production of biomass for energy from shoots as short-rotation dendroenergy crops. 展开 ...
As the leaves of apple trees became fully expanded in May, the rate of photosynthesis was high in various parts of the crown. However, between the end of June and early August, the rate of photosynthesis declined rapidly in the shaded crown interior (Porpiglia and Barden, 1980). ...
Inheritance of Wood Specific Gravity in Hardwoods Not as much is published on the inheritance of specific gravity inhardwoodsas in conifers, but the information is still substantial. Most of the work was done oneucalyptsandpoplars, with some on other species. In general, wood specific gravity is...

As noted above, the toxicity shown by silica sols toward certain cells and membrane-bound organelles can be offset by the addition of various polymers, presumably through competition between the polymers and the membrane surface for active sites on the silica. Pertoft reasoned that the polymer ...
