Age-related changes in melatonin synthesis in rat extrapineal tissues
In the search of new therapeutic targets improving the quality of life of elderly, melatonin, “the chemical expression of darkness”, seems to play a remarkable role in aging process possibly due to its antioxidant, ...
Complex concept lattices for simulating human prediction in sport
In order to address the study of complex systems, the detection of patterns in their dynamics could play a key role in understanding their evolution. In particular, global patterns are required to detect emergent concepts ...
Influences of the solid load on the microstructure and compressive behavior of Fe2O3 scaffolds manufactured by freeze-casting using stearic acid as dispersant agent
(Elsevier Ltd, 2022)
Porous materials manufactured by freeze-casting are demonstrating potential application as oxygen carriers for the production and purification of hydrogen, or anode material for lithium-ion batteries. However, to obtain ...
On the Concurrent Execution of Model Transformations with Linda
(ACM Digital Library, 2013)
Nowadays there exists a wide variety of model transforma-tion languages. However, all of them present limitations, mainly performance issues, when the complexity and size of model transformations and models grow. The ...
On manifolds with nonhomogeneous factors
We present simple examples of finite-dimensional connected homogeneous spaces (they are actually topological manifolds) with nonhomogeneous and nonrigid factors. In particular, we give an elementary solution of an old ...
Solitary wave billiards
(American Physical Society, 2023-03)
In the present work we explore the concept of solitary wave billiards. That is, instead of a point particle, we examine a solitary wave in an enclosed region and examine its collision with the boundaries and the resulting ...
Quasidiscrete microwave solitons in a split-ring-resonator-based left-handed coplanar waveguide
We study the propagation of quasidiscrete microwave solitons in a nonlinear left-handed coplanar waveguide coupled with split-ring resonators. By considering the relevant transmission line analog, we derive a nonlinear ...
T-MOOC, cognitive load and performance: analysis of an experience
(Asociación Universitaria de Formación del Profesorado (AUFOP), 2023-01-10)
The study of cognitive load allows us to investigate the effectiveness of any training proposal mediated by technology. This paper presents the results of the implementation of a t-MOOC produced following the DigCompEdu ...
The discourse-pragmatic functions of if/si-constructions in English and Spanish spoken academic discourse
(De Gruyter Mouton, 2023)
Although if/si constructions are usually defined as conditional constructions which exhibit cause-consequence paterns, prior research has evidenced that these constructions may fulfil a wider range of ...
Electromembrane Extraction Based on Biodegradable Materials: Biopolymers as Sustainable Alternatives to Plastics
Green and environmentally friendly approaches are increasingly necessary when developing new analytical methodologies. Electromembrane extraction (EME) has contributed to this by offering new alternatives to the traditional ...
