Objective: In this work the drug release behaviour from inert porous matrices formed according to the dual site-bond model, and according to determinist fractal structures, specifically structures type Menger sponge is studied. Methods: First, the threedimensional inert porous matrices are formed, these matrices are formed according to the rules of...
This work was made to study the influence of different factors as density (high and low), spatial patterns of distribution (clumped and random) and species composition on survival and growth rates, intensity of competition and finally on the biomass production, under controlled experimental conditions. Two annual plants species from the...
