VISCOUS-FLOW MECHANISM OF #6 FUEL OIL – PALM OLEIN MIXTURES
Viscous-flow mechanism of #6 fuel oilpalm olein mixtures
The viscosities of mixtures of #6 fuel oil and palm olein at 60 °C do not obey Kendall-‐‐Monroe equation. Molecular considerations predict deviation from ideal-‐‐mixture ...
SYNTHESIS, CHARACTERIZATION AND REDOX BEHAVIOUR OF MIXED LIGAND COPPER(II) SACCHARINATE COMPLEXES
Synthesis, characterization and redox behaviour of mixed ligand copper(II) saccharinate complexes
Three mixed-ligand complexes of Cu(II) with saccharin (sac), pyrazole, (Hpz), imidazole, (Himid) were synthesized and characterized on the basis of elemental analysis, FT-IR spectroscopy, magnetic susceptibility, EPR ...
SOLUCIÓN DE UNA ECUACIÓN DIFERENCIAL PARCIAL DE DIFUSIÓN
Solución de una ecuación diferencial parcial de difusión
Utilizing the Laplace transform, an algorithm is shown that solves the partial differential equation, product from the application of the Fick ́s second law of diffusion. ...
THE LEGACY OF VAN DER WAALS
The legacy of van der Waals
The physical implications of the form and nature of the van der Waals equation of state are explained. The relation of this equation to so-‐‐called van der Waals ...
Graph Theory and simple Hueckel Theory applied to benzene
We compare the results of application of graph theory and of simple Hueckel theory in its traditional form to benzene, as an instance of a conjugated molecular system. The ...
COMPARACIÓN DE METODOLOGÍAS DE EXTRACCIÓN PARA LIMONENO Y CARVONA EN Lippia alba USANDO CROMATOGRAFÍA DE GASES.
Comparación de metodologías de extracción para limoneno y carvona en lippia alba usando cromatografía de gases.
Abstract Different plants drying procedures, hydrodistillation and solvent extraction by sonication were evaluated for the essential oil extraction of Lippia alba. Quantitative ...
Evaluation of three chroroplastic markers for barcoding and for phylogenetic reconstruction purposes in native plants of Costa Rica
DNA barcoding has been proposed as a practical and standardized tool for species identification. However, the determination of the appropriate marker DNA regions is still a major ...
IMPACTO DEL CRECIMIENTO ECONÓMICO INDUSTRIAL SOBRE LOS RECURSOS ENERGÉTICO E HÍDRICO EN COSTA RICA
Impacto del crecimiento económico industrial sobre los recursos energético e hídrico en Costa Rica
An empirical relationship between water consumption, energy consumption and industrial GDP was established, for the case of Costa Rica. This relationship may be useful in ...
