Ambiguities and symmetry relations associated with fermionic tensor densities
(2004-01-01)
We consider the consistent evaluation of perturbative (divergent) Green functions associated with fermionic tensor densities and the derivation of symmetry relations for them. We show that, in spite of current algebra ...
Adaptive seismic ground roll attenuation using the double density dual tree discrete wavelet transform (dwt) method
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2012)
Seismologists working on the reflection of seismic data have been dealing with noise and trying to attenuate noise as much as possible without damaging a particular signal. Many methods have been used to removenoise types, ...
Near infrared spectroscopy for soil bulk density assessment
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
P>Soil bulk density values are needed to convert organic carbon content to mass of organic carbon per unit area. However, field sampling and measurement of soil bulk density are labour-intensive, costly and tedious. ...
A cross-sectional study of the forearm bone density of long-term users of levonorgestrel-releasing intrauterine system

Direct variational determination of the two-electron reduced density matrix for doubly occupied-configuration-interaction wave functions: The influence of three-index N -representability conditions
(American Institute of Physics, 2018-01)
This work proposes the variational determination of two-electron reduced density matrices corresponding to the ground state of N-electron systems within the doubly occupied-configuration-interaction methodology. The P, Q, ...
Local electronic structure, optical bandgap and photoluminescence (PL) properties of Ba(Zr0.75Ti0.25)O3 powders
(2013-06-01)
Ba(Zr0.75Ti0.25)O3 (BZT-75/25) powders were synthesized by the polymeric precursor method. Samples were structurally characterized by X-ray diffraction (XRD), Rietveld refinement, X-ray absorption near-edge structure (XANES) ...

Mebendazole spectrophotometric determination. Theoretical and experimental study of the interaction with sodium hydroxide
(Asian Journal of Science and Technology, 2016-11-30)
USP, EP, and Argentinian Pharmacopoeia proposed HPLC-UV for quantitative quality control of mebendazole (MBZ) tablets. In this work, a spectrophotometric method is proposed. A mebendazole solution was prepared by dissolving ...
Direct measurement and prediction of bulk density on alluvial soils of central Chile
(Inst Investigaciones Agropecuarias, 2016)
The significance of soil bulk density (rb) as a key indicator
of soil quality was examined in this study. Bulk density
values obtained by direct methods (clod, cylinder, and
excavation) with three sample sizes (small, ...
