A densidade básica e característica anatômicas variam radialmente na madeira de Astronium graveolens Jacq. (Anacardiaceae). Basic density and anatomical features vary in the radial direction in the wood of Astronium graveolens Jacq. (Anacardiaceae). [PDF]

open access: yesRevista do Instituto Florestal, 2011
Estudos sobre variações nas dimensões celulares de espécies arbóreas de clima tropical são escassos. Sendo assim, o objetivo deste trabalho foi caracterizar a variação da densidade básica e da anatomia no sentido radial da madeira de Astronium graveolens

Quantum many-body dynamics in a Lagrangian frame: II. Geometric formulation of time-dependent density functional theory

open access: yes, 2005
We formulate equations of time-dependent density functional theory (TDDFT) in the co-moving Lagrangian reference frame. The main advantage of the Lagrangian description of many-body dynamics is that in the co-moving frame the current density vanishes ...

Variação radial da retratibilidade e densidade básica da madeira de Eucalyptus saligna Sm. Radial variation of shrinkage and specific gravity in Eucalyptus saligna Sm. wood

open access: yesRevista Árvore, 2003
A ultra-estrutura e a composição química da madeira, bem como suas propriedades físicas e mecânicas, variam significativamente entre espécies, entre árvores de uma mesma espécie e, mesmo, entre diferentes partes de uma mesma árvore.

WOOD QUALITY OF Pinus patula Schltdl & Cham FOR THE PULP PRODUCTION [PDF]

open access: yesRevista Árvore, 2019
The softwood pulp industry is based on the supply of Pinus taeda and P. elliottii woods, and competes for this raw material with other timber sectors. The study aimed to evaluate the wood quality of Pinus patula for pulp and paper production.

Time-dependent current density functional theory via time-dependent deformation functional theory: A constrained search formulation in the time domain [PDF]

open access: yes, 2009
The logical structure and the basic theorems of time-dependent current density functional theory (TDCDFT) are analyzed and reconsidered from the point of view of recently proposed time-dependent deformation functional theory (TDDefFT).

A (1+1) dimensional example of Quarkyonic matter

open access: yes, 2012
We analyze the (1+1) dimensional QCD (QCD_2) at finite density to consider a number of qualitative issues: confinement in dense quark matter, the chiral symmetry breaking near the Fermi surface, the relation between chiral spirals and quark number ...

Personalizing the Pediatric Hematology/Oncology Fellowship: Adapting Training for the Next Generation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT The pediatric hematology‐oncology fellowship training curriculum has not substantially changed since its inception. The first year of training is clinically focused, and the second and third years are devoted to scholarship. However, this current structure leaves many fellows less competitive in the current job market, resulting in ...

Neuro-fuzzy Hybrid System for Monitoring Wood Moisture Content During Drying

open access: yesFloresta e Ambiente, 2019
The heterogeneous behavior of wood during drying is a process difficult to control. The objective of this study was to evaluate the accuracy of the neuro-fuzzy hybrid system for monitoring wood moisture during drying.
