La ciudad medieval como escenario: primeras manifestaciones del teatro popular

Reunimos aquí el material relacionado con una serie de fiestas que se desarrollan en la ciudad medieval, haciendo hincapié en las fiestas populares y en la organización del espacio urbano medieval como espacio teatral

Biorefineries: Achievements and challenges for a bio-based economy

Funding This work was supported by a project (FQM-176) financed by the Junta de Andalucía. FM-M, acknowledges the support from the Global Challenges Research Fund from Swansea University, and from the Royal Society of Chemistry Enablement Grant (E21-7051491439).Climate change, socioeconomical pressures, and new policy and legislation are driving a decarbonization process across industries, with a critical shift from a fossil-based economy toward a biomass-based one. This new paradigm implies not only a gradual phasing out of fossil fuels as a source of energy but also a move away from crude oil as a source of platform chemicals, polymers, drugs, solvents and many other critical materials, and consumer goods that are ubiquitous in our everyday life. If we are to achieve the United Nations’ Sustainable Development Goals, crude oil must be substituted by renewable sources, and in this evolution, biorefineries arise as the critical alternative to traditional refineries for producing fuels, chemical building blocks, and materials out of non-edible biomass and biomass waste. State-of-the-art biorefineries already produce cost-competitive chemicals and materials, but other products remain challenging from the economic point of view, or their scaled-up production processes are still not sufficiently developed. In particular, lignin’s depolymerization is a required milestone for the success of integrated biorefineries, and better catalysts and processes must be improved to prepare bio-based aromatic simple molecules. This review summarizes current challenges in biorefinery systems, while it suggests possible directions and goals for sustainable development in the years to come.Project (FQM-176) financed by the Junta de AndalucíaGlobal Challenges Research Fund from Swansea UniversityRoyal Society of Chemistry Enablement Grant (E21-7051491439

Disjointly Homogeneous Banach Lattices and Applications

This is a survey on disjointly homogeneous Banach lattices and their applications. Several structural properties of this class are analyzed. In addition we show how these spaces provide a natural framework for studying the compactness of powers of operators allowing for a unified treatment of well-known results

A Proposal to Define Adaptive Learning Designs

Abstract. This paper outlines a framework to describe adaptive learning designs where definitions as the instructional design method, the type of tests, the learning style approach, and the adaptive rules are not prescribed. Standardized metadata based on IMS is used to guarantee the reusability and interoperability of the elements. The framework proposes, also, to adjust the learning design taking into account the student knowledge and the learning style of both the learner and the learning activities by means of adaptive rule definitions. These rules are defined using a set of elements (based on IMS LD) and they describe adaptive statements, techniques and students’ stereotypes
