Parametric Modeling CAD-CAM of the Ankle and Pathological Related Situations
2014
It is primary object of the present study to create a 3D model of the human ankle and an axis system that will show the position the tibia and the foot on a healthy subject. Regarding this scope of the study, the first step in obtaining the 3D model of the bones is scanning. The graphic modeling software used is Catia V5 R20. It is another object of the present study to create an axis system that will be very easy to maneuver and on which we can show different pathological situations, not only on a healthy subject, creating their assembly reference systems considering the mechanical and anatomical axes existing and creating prerequisites for the study of different possible pathological situ…
Autonomy and ICT in Environmental Education
2012
[EN] This paper aims at tackling the need for appropriate knowledge when addressing Environmental Education (EE) from an autonomous and critical viewpoint. It also aims at showing the need for the appropriation of ICT with a view to foster the perception of the environmental complexity, as well as the construction of a new kind of environmental knowledge and awareness. These two factors should be capable of modifying the way human beings behave and relate to their environment. Before looking at effective ways to achieve this goal, a suitable praxis should be developed in such a way that a new environmental awareness emerges. This new praxis should in turn help foster the autonomy of both ed…
A comparative double blind study of nasal dressing sponge® versus merocel® as nasal pack after nasal surgery
2021
Introduction: Nasal packing is a common procedure used to ensure haemostasis after nasal surgery. Materials and Methods: A prospective, randomized, controlled and double-blinded study was conducted on 80 consecutive subjects to investigate whether using Nasal Dressing Sponge® (NDS) instead of simple Merocel® might improve patients' postoperative experience of nasal packing. Results: During the stay of the tampons no differences were noticed between the two groups as regards the postoperative pain. When it comes to pain during the packing removal, patients complained of worse symptoms in the side packed with Merocel. There was no bleeding after the removal of Merocel, whereas 5,6% patients w…
Colorectal cancer defeating? Challenge accepted!
2013
Colorectal tumours are actually considered as aberrant organs, within it is possible to notice a different stage of cell growth and differentiation. Their origin is reported to arise from a subpopulation of tumour cells endowed with, just like the healthy stem cells, self-renewal and aberrant multi-lineage differentiation capacity likely to be called colorectal cancer stem cells (CCSCs). Cancer stem cells (CSCs) fate, since their origin, reflects the influences from their microenvironment (or niche) both in the maintenance of stemness, in promoting their differentiation, and in inducing epithelial-mesenchymal transition, responsible of CSCs dissemination and subsequent formation of metastat…
On numerical simulation of electromagnetic field effects in the combustion process
2018
This paper deals with a simplified model taking into account the interplay of compressible, laminar, axisymmetric flow and the electrodynamical effects due to Lorentz force’s action on the combustion process in a cylindrical pipe. The combustion process with Arrhenius kinetics is modelled by a single step exothermic chemical reaction of fuel and oxidant. We analyze non-stationary PDEs with 6 unknown functions: the 3 components of velocity, density, concentration of fuel and temperature. For pressure the ideal gas law is used. For the inviscid flow approximation ADI method is used. Some numerical results are presented.
Características organizativas y didácticas del concierto didáctico. Un estudio de caso sobre la coordinación entre profesorado de Música de Educación…
2019
The main goal of this study is to determine which characteristics of didactic concerts, an extracurricular activity at Primary and High Schools in Manises (Spain), facilitate the coordination between Primary and Secondary staffs of the educational centers under consideration. Such coordination endeavors a smooth transition of the students from Primary to Secondary educational stages. The theoretical framework follows the lines of collaboration and teaching coordination, didactic concerts and the transition between the two educational stages. A questionnaire, a focus group, and a memorandum of the aforementioned staff have been used to reveal the perceptions of the informants from a qualita…
Optical Imaging of Coherent Molecular Rotors
2020
International audience; Short laser pulses are widely used for controlling molecular rotational degrees of freedom and inducing molecular alignment, orientation, unidirectional rotation and other types of coherent rotational motion. To follow the ultra-fast rotational dynamics in real time, several techniques for producing molecular movies have been proposed based on the Coulomb explosion of rotating molecules, or recovering molecular orientation from the angular distribution of high-harmonics. The present work offers and demonstrates a novel non-destructive optical method for direct visualization and recording of movies of coherent rotational dynamics in a molecular gas. The technique is b…
Characterization of nuclear effects in muon-neutrino scattering on hydrocarbon with a measurement of final-state kinematics and correlations in charg…
2018
This paper reports measurements of final-state proton multiplicity, muon and proton kinematics, and their correlations in charged-current pionless neutrino interactions, measured by the T2K ND280 near detector in its plastic scintillator (C$_8$H$_8$) target. The data were taken between years 2010 and 2013, corresponding to approximately 6$\times10^{20}$ protons on target. Thanks to their exploration of the proton kinematics and of kinematic imbalances between the proton and muon kinematics, the results offer a novel probe of the nuclear-medium effects most pertinent to the (sub-)GeV neutrino-nucleus interactions that are used in accelerator-based long-baseline neutrino oscillation measureme…
Populismo municipal y nacionalcatolicismo en la Valencia del general Primo de Rivera: el marqués de Sotelo (1923-1930) = Populism and Municipal Propa…
2016
El presente trabajo pretende explicar las principales características políticas del régimen de Primo de Rivera en la ciudad de Valencia. Desde un análisis de la política municipal, el populismo y la publicidad de la construcción de obras públicas se presentan como los principales pilares para la consolidación del régimen en Valencia. La praxis política del marqués de Sotelo supuso para la ciudad el primer contacto con el nacionalcatolicismo. La figura de este alcalde, además, ocupa buena parte del texto al ser un fiel exponente de las prácticas políticas nacidas tras el golpe de septiembre de 1923.This paper aims to explain the main features of the political regime of Primo de Rivera in the…
Efficacy of hexaflumuron against the fungus-growing termitePseudacanthotermesspiniger(Sjöstedt) (isoptera, macrotermitinae)
1998
The efficacy of hexaflumuron, a benzophenylurea insecticide, has been studied for the first time on a fungus-growing termite (Pseudacanthotermes spiniger Sjostedt, Macrotermitinae). Results show that hexaflumuron could be useful in treating infestations of such pest species, which are of great economic importance in many tropical and equatorial countries. Foraging workers harvested and introduced treated food into the nest and subsequently contaminated the brood by trophallaxis. Hexaflumuron showed potent larvicidal activity. The compound did not appear to be rapidly degraded by the digestive enzymes of termite workers, nor by the symbiotic fungus Termitomyces eurhizus Heim growing on fungu…
