¿Matrices policóricas / tetracóricas o matrices Pearson?: Un estudio metodológico
(Universidad San Ignacio de Loyola, 2014)
The use of product-moment correlation of Pearson is common in most studies in factor analysis in psychology, but it is known that this statistic is only applicable when the variables related are in interval scale and ...

Cell Differentiation and Bone Protein Synthesis in the Lungs of Sheep with Spontaneous Calcinosis
(Elsevier, 2000-11)
The lungs of three sheep with spontaneous enzootic calcinosis induced by the calcinogenic plantNierembergia veitchii (Nv) were examined electron microscopically and immunohistochemically. The main ultrastructural changes ...

Estimating models for predicting effective permeability of mixed matrix membranes
(Elsevier Science, 2006-06)
Mixed matrix membranes have become a highly potential unique materials in many engineering application to overcome limitations presented by other products. In this contribution, an improved form of Maxwell's equation (the ...
Self-aggregation in pyrrole: Matrix isolation, solid state infrared spectroscopy, and DFT study
(American Chemical Society, 2004-08)
Pyrrole (C4H5N) was embedded in low-temperature solid inert matrixes (argon, xenon; T = 9 K.) and both the monomer and low-order aggregates characterized by FTIR spectroscopy. The spectroscopic studies were complemented ...
Carbon nanotubes grown on carbon fiber yarns by a low temperature CVD method: A significant enhancement of the interfacial adhesion between carbon fiber/epoxy matrix hierarchical composites
(Elsevier Ltd, 2017-03)
In this work, we show that the interfacial adhesion between carbon fibers (CFs) and epoxy matrix in laminated composites can be significantly enhanced by the chemical vapor deposition (CVD) growth of multiwalled carbon ...
ABS copolymer-activated carbon mixed matrix membranes for CO 2/CH4 separation
(Elsevier Science, 2004-11-01)
The performance of various novel mixed matrix composite (MMC) membranes for separation of CO2 from CH4 was investigated as a function of carbon loading. Acrylonitrile-butadiene-styrene (ABS) copolymer was used as the polymer ...
