1. Preparation of Poly(3-hydroxybutyrate-b-ε-caprolactone) by Reactive Extrusion and Production of Electrospun Fibrous Mats
Poly(3-hydroxybutyrate) (PHB) has been proposed to be a potential candidate to be used as biomaterial. However, its poor processability, high brittleness and rigidity have limited its applicability. Transesterification reactions with poly(ε-caprolactone) (PCL), one of the most promising biomedical materials, emerge as an attractive alternative to improve it

2. Materials from renewable resources: new properties and functions
Abstract: Sustainable production requires increasing use of raw materials from renewable sources, processed under mild conditions with minimal effluent production. These requirements are satisfied by using materials derived from biomass, in synergy with food and energy production. The possibilities of biomass are continuously enlarged by new findings, as in

4. Influencia de la temperatura en ensayos de arrancamiento sobre diferentes sistemas epoxi-acero de uso en conectores de ductos flexibles
ABSTRACT In the offshore oil fields located in deep and ultra-deep waters they are used flexible pipes. In many cases inside these pipes, the hydrocarbons are transported at elevated temperatures. At the ends of the flexible pipes are installed end fittings, these are the connection with sea platforms and different subsea systems. In the assembly of end fitt

5. Caracterización de resinas epoxi para uso en conectores de ductos flexibles
ABSTRACT In the offshore productions of gas and oil are frequently used flexible pipes. The end fitting is the connection between the flexible pipe body and the production unit, at the assembly of this component is used epoxy resin to fill the free space inside it. This polymeric material holds the tensile armor wires to form the anchoring system. A critical

8. Recycling assessment of multilayer flexible packaging films using design of experiments
AbstractThe viability of recycling post-industrial packaging waste, compounded from multilayer laminated PET-PE films, for production of polymer blends with good physico-mechanical performance is analyzed. Initially, several PET-PE model-blends were prepared from fresh polymers and were compounded with different formulations, based on design of experiments (

9. A review of three decades of research on some combinatorial optimization problems
This paper presents an overview of our research in combinatorial optimization problems. Over the last three decades, our team has been studying mostly optimization problems that arise in industrial environments through the elaboration and solution of mathematical decision models. In addition to elaborating innovative models, we have improved upon existing so

12. Greenhouse tomato production with electricity generation by roof-mounted flexible solar panels
The integration of renewable energy sources into greenhouse crop production in southeastern Spain could provide extra income for growers. Wind energy could be captured by small to medium-sized wind turbines, gas could be produced from biomass, and solar energy could be gathered by solar panels. The aim of this study was to examine the effect of flexible sola
