Fast state and trap rotation of a particle in an anisotropic potential
(IOP Publishing, 2019-10-21)
We study the dynamics of a quantum or classical particle in a two-dimensional rotating anisotropic harmonic potential. By a sequence of symplectic transformations for constant rotation velocity we find uncoupled normal ...
Fast atom transport and launching in a nonrigid trap
(Springer Nature, 2017-07-18)
We study the shuttling of an atom in a trap with controllable position and frequency. Using invariant-based inverse engineering, protocols in which the trap is simultaneously displaced and expanded are proposed to speed ...
Deep-sea benthic response to rapid climatic oscillations of the last glacial cycle in the SE Bay of Biscay
(Elsevier, 2017-06-09)
Paleoclimatic evolution of the last 140 ka (Marine Isotopic Stages MIS 1 to MIS 5) in the South Bay of Biscay has been studied by considering microfossil changes in sediment samples of deep core PP10-17. This core was ...
Effects of adult enriched environment on cognition, hippocampal- prefrontal plasticity and NMDAR subunit expression in MK-801- induced schizophrenia model
(Elsevier, 2019-05-01)
Schizophrenia is a mental disorder characterized by psychosis, negative symptoms and cognitive impairment. Cognitive deficits are enduring and represent the most disabling symptom but are currently poorly treated. N-methyl ...
Deactivation kinetics for the conversion of dimethyl ether to olefins over a HZSM-5 zeolite catalyst
(2016-11-16)
A deactivation kinetic equation for the conversion of dimethyl ether (DME) to olefins (DTO process) has been established. The catalyst has been prepared with a HZSM-5 zeolite (SiO2/Al2O3 ratio of 280) agglomerated with ...
Effect of a PBL teaching method on learning about nursing care for patients with depression
(Elsevier, 2017-02-21)
El objetivo de este estudio fue analizar el conocimiento declarativo y argumentativo adquirido en relación al tema de los cuidados de enfermería en la depresión en dos grupos de estudiantes de enfermería, comparando los ...
Emakumea Pilotari: The Impact of a Recreational Programme Designed with and for Female Basque Pelota Players
(Generalitat de Catalunya. Departament de la Presidència. Institut Nacional d’Educació Física de Catalunya, 2019)
This study aimed to evaluate the impact of the Emakumea Pilotari (female Basque pelota player) programme organised by the Gipuzkoan Federation of Basque Pelota on the participants. The data were extracted from an ethnography ...
Application of the dual integrated force method to the analysis of the off-axis three-point flexure test of unidirectional composites
(SAGE Journals, 2015-03-13)
This paper shows the use of the dual integrated force method in the finite element method and its application to unidirectional composite laminates. This method was developed by SN Patnaik for isotropic materials, considering ...
Calculation of positron characteristics for elements of the periodic table
(IOP Publishing Ltd, 2011-01-10)
Positron lifetimes have been calculated in bulk and monovacancies for most of the elements of the
periodic table. Self-consistent and non-self-consistent schemes have been used for the calculation of the
electronic ...
Determining Flinders' bar correction by heeling the ship
(Spanish Society of Maritime Research (SEECMAR), 2013)
The aim of this article is to provide the compass adjuster with an innovative method of determining thelength of Flinders’ bar while the ship’s latitude remains unaltered. In this way the definitive compass ad-justment may ...
