Spectrum of QCD at Finite Isospin Density

open access: yes, 2017
We study the phase diagram of QCD at finite isospin density using two flavors of staggered quarks. We investigate the low temperature region of the phase diagram where we find a pion condensation phase at high chemical potential.

Longitudinal and Transverse Variation in the Physical Properties of Wood Red Tauari

open access: yesFloresta e Ambiente
The objective of this work was to study the fiber length variation, retractability and basic density, in the core-bark direction and along the heig of the red tauari wood (Cariniana micrantha Ducke). The stem was evaluated in the discs, from core to bark,

Water Flow Evaluation in Eucalyptus and Corymbia Short Logs

open access: yesFloresta e Ambiente, 2018
The aim of this study is to evaluate the free and adsorbed water flow in short logs of Eucalyptus urophylla and Corymbia citriodora clones. 40 cm long, short logs were extracted from the base of the trees. Three trees each of C.

Electromagnetic field energy density in artificial microwave materials with negative parameters

open access: yes, 2004
General relations for the stored reactive field energy density in passive linear artificial microwave materials are established. These relations account for dispersion and absorption effects in these materials, and they are valid also in the regions ...

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

Effects of potassium/sodium fertilization and water availability on wood properties of Eucalyptus grandis trees [PDF]

open access: yes, 2019
In Brazil. most Eucalyptus plantations are located in regions experiencing periods of water shortage where fertilizers such as potassium (K) are intensively used to achieve high productivity. Recently.

Coarse-grained forms for equations describing the microscopic motion of particles in a fluid

open access: yes, 2013
Equations of motion for the microscopic number density $\hat{\rho}({\bf x},t)$ and the momentum density $\hat{\bf g}({\bf x},t)$ of a fluid have been obtained in the past from the corresponding Langevin equations representing the dynamics of the fluid ...

Basics of the density functional theory

open access: yesAIMS Materials Science, 2017
The density functional theory (DFT) established itself as a well reputed way to compute the electronic structure in most branches of chemistry and materials science. In the formulation given by Kohn, Hohenberg and Sham in the 1960's, the many-electron wave function is replaced by the electron density, so that the energy is just a functional of the ...

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 ...
