Gravitational Energy-Momentum Density in Teleparallel Gravity
(2000-05-15)
In the context of a gauge theory for the translation group, a conserved energy-momentum gauge current for the gravitational field is obtained. It is a true spacetime and gauge tensor, and transforms covariantly under global ...
Cost and energy density of diet in Brazil, 2008-2009
(CADERNOS SAUDE PUBLICARIO DE JANIERO, 2012)
This study aimed to evaluate the relationship between the cost and energy density of diet consumed in Brazilian households. Data from the Brazilian Household Budget Survey (POF 200812009) were used to identify the main ...
Changes in irradiance and energy density in relation to different curing distances
(Sociedade Brasileira de Pesquisa Odontológica - SBPqO, 2015)
The present study aimed to assess the influence of curing distance on the loss of irradiance and power density of four curing light devices. The behavior in terms of power density of four different dental curing devices ...
Accuracy of nonlinear feed formulation for broiler chickens: maximising broiler profit
(2012)
The modeling technique is simple, useful and practical to calculate optimum nutrient density to maximize profit margins, using nonlinear programming by predictive broiler performance. To demonstrate the influence of the ...
One-dimensional superfluid Bose-Fermi mixture: Mixing, demixing, and bright solitons
(2007-08-28)
We study an ultracold and dilute superfluid Bose-Fermi mixture confined in a strictly one-dimensional (1D) atomic waveguide by using a set of coupled nonlinear mean-field equations obtained from the Lieb-Liniger energy ...

Molecular structure and bonding of copper cluster monocarbonyls CunCO (n=1-9)
(AMER CHEMICAL SOC, 2006)
In this work we analyze CO binding on small neutral copper clusters, Cu-n (n = 1-9). Molecular structures and reactivity descriptors of copper clusters are computed and discussed. The results show that the condensed Fukui ...
