The polymeric nanoparticles are prepared from biocompatible polymers in size between 10-1000 nm. Chitosan is a biocompatible polymer that - can be utilized as drug delivery systems. In this study, chitosan nanoparticles were synthesized using an optimized spontaneous emulsification method. Determining particle size and morphology are two critical parameters in nanotechnology. The aim of this st...

Most recent developments in polymers from renewable resources have focused on thermoplastics, whereas there has been no comparable development of plastics with elastomeric properties. Here we evaluate the possibility of developing renewable elastomers based on starch. Potato starch plasticized with glycerol (called plasticized starch, or PLS) was melt-blended with small quantities (5 wt % or 15...

Abstract The aim of the research is to identify strength and direction development relationship between formal informal institutions assess institutional equilibrium modern economies. structural equations modelling based on partial least squares (SEM-PLS) applied achieve purpose article. It an econometric method that allows measurement analysis dependencies latent variables (measures cannot be ...

Abstract Organizations characterized by a climate and culture of competition overwork facilitate the emergence workaholism phenomenon, as they provide favorable conditions for employees to spend more time in workplace. Many these are successful their careers both financial terms job satisfaction. This article aims study influence on perception career success. The sample consists 234 Portuguese ...
