Case study: Microfibril angle and its relationship with basic density in Pinus taeda L. wood from silvopastoral systems
(Associação Brasileira Técnica de Papel e Celulose, 2013-05)
The material resulting from fast-growing plantations is presumed
to present a high percentage of juvenile wood, with high microfibril
angle (MFA) and low basic density (BD), which would negatively
affect the technological ...
Phenotypic variation of basic wood density in Pinus ponderosa plus trees = Variación fenotípica de la densidad básica de la madera de árboles plus de Pinus ponderosa
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)
Phenotypic selection generally reduces the variability of both the selected trait and other associated characteristics. Some species show a negative strong relationship between growth traits and wood ...
DFT broken-symmetry exchange couplings calculation in a 1D chain of bridged iron basic carboxylates
(Pergamon-Elsevier Science Ltd, 2009-06)
DFT broken-symmetry calculations at the B3LYP level were carried out to evaluate the exchange coupling constants defined by the Heisenberg-Dirac-van Vleck spin Hamiltonian (HDvV), Ĥ = -2JŜaŜb, in a 1D chain of iron basic ...

(Universidad Nacional de Misiones. Facultad de Ciencias Forestales. Instituto Subtropical de Investigaciones Forestales, 2005-12-01)
El objetivo del trabajo fue determinar las variaciones en sentido axial y radial de la densidad básica de la madera de Salix babylonica L. X Salix alba L. cv. "A-131-25” y Salix babylonica var. sacramenta H., cultivados ...
Assessment of resistance to xylem cavitation in cordilleran cypress using near-infrared spectroscopy
(Elsevier Science, 2020-04)
Characterizing drought resistance of forest trees is an important aim in the worldwide context of increasing forest decline and dieback. Furthermore, wood demand is increasing all around the world, urging the need for the ...
Eucalyptus globulus en el sudeste de la provincia de Buenos Aires: edades, procedencias y densidad de la madera
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-08)
Los objetivos del presente trabajo fueron describir el recurso forestal de Eucalyptus globulus Labill. (Eucalipto blanco) implantado en el sudeste de la provincia de Buenos Aires, Argentina, en términos de edad, procedencias ...
Characterization and Behaviour of Pt Catalysts Supported on Basic Materials in Dry Reforming of Methane
(Brazilian Society of Chemical Engineering, 2019-06)
Different basic materials, such as K-L zeolite, K-Al2O3, K-Mg/Al mixed oxide and MgO, were used as supports of Pt-catalysts for the dry reforming of methane (DR) reaction. The effects of the distribution of basic strength ...
Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)
Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ...
The effect of blending granular aggregates of different origin on the strength of concrete
(Elsevier Science, 2012-03-01)
This work correlates the resistance of concrete cores with the physical properties of the granular material forming it. A basic physical characterization is conducted, taking into account the origin of the grains involved ...
The key role of adsorbate-catalyst interactions into catalytic activity of [CTA+]-Si-MCM-41 from electron density analysis
(Elsevier, 2021-02-23)
In this work, we analyzed the role of the interactions involved in the reaction mechanism for the transesterification of ethyl acetate and methanol on the pore mouth of [CTA+]-Si-MCM-41 catalyst. The Quantum Theory of Atoms ...
