Geological risk assessment for rock art protection in karstic caves (Alkerdi Caves, Navarre, Spain)
(Elsevier, 2018-02-16)
This paper sets out a methodology for calculating the potential zone of damage to which an Item of Cultural Interest (ICI) located in a karst environment is exposed. An itemised study of the geological characteristics of ...
Increasing Stability of Biotin Functionalized Electrospun Fibers for Biosensor Applications
(ACS, 2016-12-20)
This paper describes the effects of both solvent and copolymer block lengths on the stability of electrospun poly(lactic acid)/poly(lactic acid)-b-poly(ethylene glycol) (PLA/PLA-b-PEG) and PLA/PLA-b-PEG-Biotin fibers in ...
Diseño y evaluación de una intervención educativa sobre la pandemia de la COVID-19 y las medidas de prevención
(Universidad de Cádiz, 2022)
La crisis provocada por la pandemia de la COVID-19 ha llevado a la mayoría de las personas en todo el mundo a realizar un cambio en sus actividades cotidianas y ha resaltado la necesidad de una ...
A Systematic Literature Review of Integrated STEM Education: Uncovering Consensus and Diversity in Principles and Characteristics
(MDPI, 2024-09-20)
Integrated STEM education is increasingly present in classrooms and in educational research, as it is proposed as a possible strategy to improve the problems of students’ lack of interest in scientific–technological ...
Collective tunnelling of strongly interacting cold atoms in a double well potential
(Wiley, 2020-01-20)
It is known that under resonance conditions, a group of strongly interacting bosonic atoms, trapped in a double-well potential, mimics a single particle, performing Rabi oscillations between the wells. By implication, all ...
Fabrication of Thermo-responsive Cotton Fabrics Using Poly(vinyl caprolactam-co-hydroxyethyl acrylamide) Copolymer
(Elsevier, 2017-06-23)
A thermo-responsive polymer with hydrophilic to hydrophobic transition behavior, poly(vinyl caprolactam-co-hydroxyethyl acrylamide) P(VCL-co-HEAA), was prepared by copolymerization of vinyl caprolactam and N-hydroxyethyl ...
Synthesis, characterization and electrospinning of poly(vinyl caprolactam-co-hydroxymethyl acrylamide) to create stimuli-responsive nanofibers
(Elsevier, 2016-11-22)
Poly(vinyl caprolactam) (PVCL) is an especially attractive temperature-responsive polymer due to its biocompatibility and the fact that its lower critical solution temperature (LCST) is in the physiological range (32–34 ...
Relativistic time-dependent quantum dynamics across supercritical barriers for Klein-Gordon and Dirac particles
(APS, 2021-04-05)
We investigate wave-packet dynamics across supercritical barriers for the Klein-Gordon and Dirac equations. Our treatment is based on a multiple scattering expansion (MSE). For spin-0 particles, the MSE diverges, rendering ...
Dynamically Induced Heat Rectification in Quantum Systems
(APS, 2019-03-25)
Heat rectifiers are systems that conduct heat asymmetrically for forward and reversed temperature gradients. We present an analytical study of heat rectification in linear quantum systems. We demonstrate that asymmetric ...
Klein paradox for bosons, wave packets and negative tunnelling times
(Nature, 2020-11-05)
We analyse a little known aspect of the Klein paradox. A Klein-Gordon boson appears to be able to cross a supercritical rectangular barrier without being reflected, while spending there a negative amount of time. The ...
