Variation in the proportions of sapwood and heartwood in Atlas cedars, Cedrus atlantica Manetti, in Algeria

Modifications on the surface aerody- namic roughness length, soil moisture and East-Asian soil properties are included in the parameterization, which result in a large impact on

Single exposures of the 3D human lung TCCC model to aero- solized GO and GNP at realistic human exposure scenarios did not affect cell viability or compromised cell morphology, nor

The average proportion of heartwood in the lower part of the stem was substantial, e.g. 54% of the cross-section at the 5% height level, values somewhat higher than the 42% found

At Puechabon site, the mean length of the first growth units was similar in 1997 and significantly greater in the following years compared to that of the second growth units of

Comparing species, in P. nigra, there were significant differences between sapwood and bark parts at heights of less than 4.3 m. pinaster, sapwood was different from heartwood and

Contrary to models which explicitly include stand density (Maguire et al. 1991), the effect of between- tree competition is taken into account in the model through the effect on
