Formulation and Study of Some Controlled Release Tablets With Pentoxifylline Based on Hydroxypropylcellulose Matrix Obtained by Wet Granulation Method With Peg 6000

In this work three formulations of modified release tablets containing pentoxifylline 400 mg/tablet were obtained. Hydroxypropylcellulose (HPC) in di®erent ratios was used as hydrophilic matrix agent. The pentoxifylline inclusion in the matrix has been carried out by water granulation, using PEG 6000 as binder. Tablets were obtained with a single

Assessment of Human Bio-Behavior During Gait Process Using Lifemod Software

In this paper we present a set of observations concerning the analysis and assessment of human bio-behavior during gait process. In the first part of the paper the fundamental and theoretical considerations of the gait process are approached and aspects connected to malfunctions are expressed. In the second part of

Toward the Physical Basis of Complex Systems: Dielectric Analysis of Porous Silicon Nanochannels in the Electrical Double Layer Length Range

Dielectric analysis (DEA) shows changes in the properties of a materials as a response to the application on it of a time dependent electric field. Dielectric measurements are extremely sensitive to small changes in materials properties, that molecular relaxation, dipole changes, local motions that involve the reorientation of dipoles, and

Understanding the Mixing Phenomena – From Structural Stability to Chaos

Nowadays, computational fluid dynamics (CFD) becomes more and more mature. In the same time, it becomes more and more difficult to contribute fundamental research to it. Although the software tools in this area are increasing in importance, the way how CFD develops remain unpredictable, and it is part of what

Understanding Service Composition With Non-Functional Properties Using Declarative Model-to-Model Transformations

Developing applications comprising service composition is a complex task. Therefore, to lower the skill barrier for developers, it is important to describe the problem at hand on an abstract level and not to focus on implementation details. This can be done using declarative programming which allows to describe only the

Mathematical Properties of Complex Networks

Many researchers are attempting to create systems which mimic human thought, or understand speech, or beat to the best human chess-player [14]. Understanding intelligence and Creating intelligent artifacts both are the twin goals of Artificial Intelligence (AI).In more recent times, the interest is focused on problems related with Complex Networks

Preparation and Characterization of TIO2/Cds Layers As Potential Photoelectrocatalytic Materials

The TiO2/CdS semiconductor composites were prepared on indium tin oxide (ITO) substrates in di®erent mass proportions via wet-chemical techniques using bi-distilled water, acetyl-acetone, poly-propylene-glycol and Triton X-100 as additives. The composite layers were annealed in normal conditions at the temperature of 450±C, 120 min. with a rate of temperature increasing

The Respiratory Impedance in an Asymmetric Model of the Lung Structure

This paper presents a model of the respiratory tree as a recurrent, but asymmetric, structure. The intrinsic properties posed by such a system lead to a multi-fractal structure, i.e. a non-integer order model of the total impedance. The fractional order behavior of the asymmetric tree simulated as a dynamic system

Comparative Study of Single- and Multi-Wall Carbon Nanotubes With Application in Cerebral Aneurysm

Helping improve humanity is one of the promises of nanotechnology and nanomedicine. This paper will highlight some of the research findings in the nanomedicine area by testing some single- and multi-walls carbon nanotubues in rats cerebral aneurisms.
