Active transmembrane drug transport in microgravity: A validation study using an ABC transporter model
(2014-12-11)
Article
Accés obertMicrogravity has been shown to influence the expression of ABC (ATP-Binding Cassette) transporters in bacteria, fungi and mammals, but also to modify the activity of certain cellular components with structural and functional ... -

Alternative design of a space station for human habitability
(Universitat Politècnica de Catalunya, 2021-07-13)
Treball Final de Grau
Accés obertEn aquest projecte, proposaré la meva pròpia idea d'un disseny alternatiu d'una estació espacial per a l'habitabilitat humana. Al llarg de l'informe d'aquest projecte, el trucaré principalment un hàbitat espacial en lloc ... -

Bouncing loop quantum cosmology in Gauss-Bonnet gravity
(American Physical Society, 2015-12-11)
Article
Accés obertWe develop an effective Gauss-Bonnet extension of loop quantum cosmology, by introducing holonomy corrections in modified F(G) theories of gravity. Within the context of our formalism, we provide a perturbative expansion ... -
Genetic algorithm for multi-gravity assist interplanetary trajectory optimisation
(Universitat Politècnica de Catalunya, 2023-02-15)
Projecte Final de Màster Oficial
Accés obertThis master thesis presents the development of a genetic algorithm for optimizing multiplanetary gravity assist trajectories. The algorithm was designed to address the challenges of finding the most efficient trajectory ... -
Gravitational particle production in bouncing cosmologies
(2015-10-13)
Article
Accés obert© 2015 IOP Publishing Ltd and Sissa Medialab srl . It is argued that the Universe reheating in bouncing cosmologies could be explained via gravitational particle production, as due to a sudden phase transition in the ... -
Homothetic motions and Newtonian cosmology
(2014-05-07)
Article
Accés restringit per política de l'editorialWe construct a homothetic covariant Newtonian gravitation theory which unifies inertial homothetic forces and gravitational fields. This is achieved through an equivalence principle based on a local homothetic frame of ... -
On the meaning of Painlevé–Gullstrand synchronization
(2015-11-19)
Article
Accés obertFollowing on from two recent papers, here we examine the relationship between Newtonian gravitation and general relativity in more depth. This allows us to define a scalar potential which is just the proper time of the ... -
On the quantum corrected gravitational collapse
(Elsevier, 2015-06-09)
Article
Accés obertBased on a previously found general class of quantum improved exact solutions composed of non-interacting (dust) particles, we model the gravitational collapse of stars. As the modeled star collapses a closed apparent ... -
Oxygen neutronization in accreting white dwarfs
(1983)
Article
Accés obertSolid carbon-oxygen white dwarf cores have been shown to be likely initial configurations for collapse to neutron star densities. Solidification seems to entail carbon/oxygen separation, with oxygen settling at the star's ... -
