We study the irreversible growth of magnetic thin films under the influence of spatially periodic fields by means of extensive Monte Carlo simulations. We find first-order pseudo-phase transitions that separate a dynamic...

Effects induced by the incorporation of lipid II (LII) molecule into phosphatidylglycerol (PG) membranes were studied by Raman microspectroscopy. Spectral behavior of multilayer vesicles in liquid crystalline and gel pha...

BackgroundNon-compliant residues are a concern anywhere, regardless of the presence of an effective regulatory system. In Kenya, tomatoes are widely consumed, but data on pesticide contamination across different retail o...

Se reporta la evaluación de cinco fases móviles para el análisis de cefotaxima por cromatografía líquida de alta resolución con empleo de una columna en fase reversa (RP-18). Se determinan los coeficientes de corre...

En este trabajo se evaluaron dos sistemas líquido-cristalinos liotrópicos para la liberación sostenida de cafeína en ensayos in vitro: uno formado por una mezcla de Poloxamer 407 y agua, que presenta la fase cúbic...

The purpose of this work is to explore the potential of combining poloxamer 407 and carrageenan for its utilization in an injectable depot drug release system. Reverse thermal gelation of these formulations allow the loc...

Abstract This book provides a practical guide to molecular dynamics and Monte Carlo simulation techniques used in the modelling of simple and complex liquids. Computer simulation is an essential tool in studying the chem...

The parametrization and testing of the OPLS all-atom force field for organic molecules and peptides are described. Parameters for both torsional and nonbonded energetics have been derived, while the bond stretching and a...

A new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists. The possibility of a phase transition characterized by a change in ...

We assess various approximate forms for the correlation energy per particle of the spin-polarized homogeneous electron gas that have frequently been used in applications of the local spin density approximation to the exc...

"High-temperature renewable and industrial heat applications require efficient and compact solutions to address their inherent intermittency. Latent heat thermal energy storage is one such solution, acting as a buffer be...

Con la finalidad de obtener emulsiones aceite-agua de aplicación en el campo farmacéutico y cosmético, se desarrolla una técnica original de estabilización mediante el empleo de montmorillonitas naturales y montmori...

Las microemulsiones son mezclas isotrópicas, estables, claras, constituidas por una fase oleosa, una acuosa y uno o más anfifílicos. Despiertan interés a nivel farmacéutico debido a varias ventajas que ofrecen: ca...

The binary solvent system ethanol + ethyl acetate is widely used in the pharmaceutical sciences as a versatile model for studying the solubility of drugs. In this context, the excess molar volumes and the partial molar v...

"Se ha realizado un estudio comparativo de alternativas de transporte y distribución de combustibles con el fin de encontrar y evaluar soluciones para aquellas zonas que no tienen acceso a la red de Gas Natural dónde ...

Los hongos son fuente de alimento y medicina desde tiempos remotos. Por su valor nutracéutico y como fuente de nutricéuticos se han utilizado para mantener y mejorar la salud, preservar la juventud y promover la longev...

Fenofibrate is more effective drug as compared to other fibrates. But low bioavailability of it is due to its poor aqueous solubility. The purpose of present study was to improve fenofibrate dissolution through its formu...

The purpose of the present investigation was to evaluate 6-O-palmitoyl ascorbic acid (ASC16) and 6-O-lauril ascorbic acid (ASC12) for their capacity to promote permeation of Ibuprofen (IBU) through hairless mouse skin in...

Formulações de matrizes hidrofílicas para administração oral usando polissacarídeos como transportadores para libertação modificada de fármacos têm sido amplamente investigadas. No presente estudo, avaliamos ...

En la presente tesis se plantea el modelado del equilibrio entre fases de mezclas de importancia en biorrefinerías, y el desarrollo de módulos de simulación de procesos y productos. El modelo termodinámico empleado...
