Energy dependence with the number of particles: Density and reduced density matrices functionals
(Elsevier Science, 2014-02)
The energy of a physical domain within a molecular system considered as a quantum open system is analyzed as a functional of the electron distribution dependence with the number of particles. Our attention is focused upon ...
Effects of density and sowing pattern on weed suppression and grain yield in three varieties of maize under high weed pressure
We tested the hypothesis that improved weed suppression
by maize can be achieved through increased crop
density and spatial uniformity. Field experiments on
three varieties of maize sown at three densities (5, 7
and ...
Avaliação da distribuição da densidade em MDF a partir da técnica da onda de ultra-som
(2007-06-01)
The goal of this research was to determine the density distribution in medium density fiberboard (MDF), manufactured with polyurethane derived from castor oil using, ultrasonic wave technique. The equipment used in this ...

Genotypic Differences among Argentinean Maize Hybrids in Yield Response to Stand Density
(Amer Soc Agronomy, 2014-10)
Maize (Zea mays L.) stand density selection is an important management practice because yield is maximized at a particularoptimum value. Optimum stand density (OSD) varies across environments, and many have argued that ...
Forearm bone density in users of Depo-Provera as a contraceptive method

Non-structural carbohydrate metabolism, growth, and productivity of maize by increasing plant density
(2018-11-02)
Increasing plant density seems to improve the productivity of maize crops, and the understanding of how the metabolism of non-structural carbohydrates is affected in plants under high crop density is critical. Thus, with ...
