Este ensayo aborda el siguiente interrogante: si, como famosamente sostuvo John Rawls, la justicia es la virtud fundamental de las instituciones sociales, ¿cómo debemos entender al derecho de los contratos? En este ensayo sitúo el derecho de los contratos en…

The use of innovative technologies in education offers new possibilities that complement classroom teaching and may also help to improve the quality of education, enabling students to actively participate in the learning process. With this in mind, in 2009 the…

An experimental apparatus was designed and built to allow students to carry out heat conduction experiments in hollow cylinders made of different materials, as well as to determine the thermal conductivity of these materials. The evolution of the temperature difference…

The influence of sedentarism on the increase in obesity can now be confirmed. In this sense, attention should be paid to the importance of those working in school environments. The sample group was made up of 2,956 participants from 19…

This paper uses dynamic general equilibrium and computational methods, inspired by the multi-sector growth model structure in Stephen Turnovsky's work, to develop a theory that unifies two of the traditional explanations of structural change: sector-biased technical change and non-homothetic preferences.…

This special issue of the Journal of Physical Agents is devoted to multi-robot systems. Some might perhaps argue that the term should have been ”multi-agent systems” or ”physical multi-agent systems”, in accordance with the title of the journal. In any…

The endo-diastereo- and enantioselective 1,3-dipolar cycloaddition of azomethine ylides and electrophilic alkenes is efficiently catalysed by chiral phosphoramidite-silver(I) perchlorate complexes. The reaction allows the presence of different types of substituents in the 1,3-dipole and can be applied to the synthesis…

This special issue of the Journal of Physical Agents is devoted to human interaction with domestic robots. The form, features and future, of domestic robotic devices, from entertainment-based agents through to robotic cleaners, companions, assistants and helpers, are considered and…

Two new species of Enclisis Townes, 1970 from Spain are described and illustrated: E. dichroma sp. n. and E. schwarzi sp. n. The new species are distinguished from the closest species E. infernator and E. ornaticeps by head and leg…

Copper nanoparticles on activated carbon have been found to effectively catalyze the multicomponent synthesis of β-hydroxy-1,2,3-triazoles from a variety of epoxides and alkynes in water. The catalyst is easy to prepare, reusable at a low copper loading (0.5 mol %),…
