Abstract Fertilizers industry faces the challenge of improving the efficiency of its products either by optimizing the fertilizers in use or by developing new types of them. During the last decade, controlled and slow release technologies have become more important. These technologies aim to increase the efficiency of the applied substance by increasing its action over time and avoiding losses of all kinds (leaching, volatilization). The main purpose of the current study was to obtain a slow release biofertilizer by incorporating microalgae into a polymeric ureaformaldehyde matrix (PUFM). The quantitative analysis of macronutrients and micronutrients in… More >

Abstract Mathematical models to describe drug concentration profiles of topically administered drug in the anterior chamber aqueous humor have been proposed by several authors. The aim of this paper is to present a mathematical model to predict the drug concentration in the anterior chamber when a therapeutical contact lens with the drug entrapped in nanoparticles is used.
