En el presente artículo se evalúan las propiedades mecánicas de los materiales compuestos basados en cenizas volantes de carbón de la central termoeléctrica de Termozipa combinadas con los película extensible (Stretch film), polietilenos de baja densidad lineal de pos-consumo y polímero termoplástico parcialmente cristalino pos- industrial. Se obtuvieron mezclas variando el contenido de cenizas volantes de 0 a 50 % en peso en cada uno de los tres materiales poliméricos, dentro de una máquina mezcladora tipo Brabender. Las propiedades mecánicas evaluadas fueron: resistencia a la tracción, dureza Shore D, y absorción de energía. Los resultados obtenidos indican que en todos los casos a medida que se agrega ceniza volante las propiedades mecánicas aumentan.

This works describes the use of experimental design and surface response methodology for optimization of saponin extraction from Ampelozizyphus amazonicus. For this purpose, a method employing extraction based on maceration assisted by ultrasound technique was utilized. The following factors were studied: extraction length of time and solvent composition. The total saponin was determined by using a gravimetric method and the results expressed by their relative proportion to total crude extract. For the specific condition, 60% hydro-alcoholic solution and 18 minutes extraction length of time has shown the best results. This method can be useful for extraction of substances with biological importance
