La motivación de las tareas digitales mediante “pseudo-ApS” en Biología Celular del grado de Medicina

2020

[ES] Los grupos tutorizados de la asignatura “Biología” de 1º de Medicina (Universitat de València) son un entorno estupendo en el que desarrollas actividades que aúnen el carácter formativo conceptual con el desarrollo competencial transversal. Para ello, en el curso 19-20, hemos implementado la vinculación de la cuenta institucional UV con Microsoft 365, gracias al convenio existente entre ambas entidades para facilitar la utilización de las Tecnologías de la Información y la Comunicación (TICs) en la gestión del tiempo y del intercambio de información. Se propone a los alumnos la elaboración de objetos de aprendizaje propios y originales, en formato animación, que serán utilizados durant…

L'acceptation des dispositifs technologiquesd'auto-production par le consommateur : une approche par l'empowerment psychologique

2022

During the Covid-19 pandemic, the deployment of self-service technologies (self-checking, interactive terminals, smart devices…), allowing to substitute existing service employees and give more autonomy to consumers, have accelerated. In the french academic literature, Cova et al. (2013) conceptualized these devices as « directed self-production » technologies, underlining a more or less imposed transfer of tasks operated by firms. Among consumers, these technological devices have been subjected to ambivalent representations from consumers : some positive representations mainly related to greater autonomy for individuals exist alongside concerns about human contact degradation, macrostructu…

Internal shocks in relativistic outflows: collisions of magnetized shells

2007

(Abridged): We study the collision of magnetized irregularities (shells) in relativistic outflows in order to explain the origin of the generic phenomenology observed in the non-thermal emission of both blazars and gamma-ray bursts. We focus on the influence of the magnetic field on the collision dynamics, and we further investigate how the properties of the observed radiation depend on the strength of the initial magnetic field and on the initial internal energy density of the flow. The collisions of magnetized shells and the radiation resulting from these collisions are calculated using the 1D relativistic magnetohydrodynamics code MRGENESIS. The interaction of the shells with the externa…

Intercepting real and simulated falling objects: what is the difference?

2009

International audience; The use of virtual reality is nowadays common in many studies in the field of human perception and movement control, particularly in interceptive actions. However, the ecological validity of the simulation is often taken for granted without having been formally established. If participants were to perceive the real situation and its virtual equivalent in a different fashion, the generalization of the results obtained in virtual reality to real life would be highly questionable. We tested the ecological validity of virtual reality in this context by comparing the timing of interceptive actions based upon actually falling objects and their simulated counterparts. The r…

Bio-imaging with the helium-ion microscope: A review

2021

Scanning helium-ion microscopy (HIM) is an imaging technique with sub-nanometre resolution and is a powerful tool to resolve some of the tiniest structures in biology. In many aspects, the HIM resembles a field-emission scanning electron microscope (FE-SEM), but the use of helium ions rather than electrons provides several advantages, including higher surface sensitivity, larger depth of field, and a straightforward charge-compensating electron flood gun, which enables imaging of non-conductive samples, rendering HIM a promising high-resolution imaging technique for biological samples. Starting with studies focused on medical research, the last decade has seen some particularly spectacular …

Shining castles and humans of metal/floral appearance ? metaphorical language in the Palaiologan romances Kallimachos and Velthandros

2019

About eight centuries after Heliodorus, the Greek novel resurfaced in the twelfth century, in Komnenian Byzantium, and again two centuries later under the Palaiologan dynasty. This latter literary revival was due to the political stability of the imperial Byzantine government, which promoted cultural production, rhetorical education, and patronage networks. Kallimachos and Velthandros, two Palaiologan romances presented as court literature, combine ancient and medieval tropes with rhetorical artistry to blur the boundaries between the artificial and the natural. Castles and objects made of precious metals thus resemble living, natural spaces, and human characters are portrayed in metallurgi…

Activity against Microorganisms Affecting Cellulosic Objects of the Volatile Constituents of Leonotis nepetaefolia from Nicaragua

2014

The chemical composition of the essential oil from aerial parts of L. nepetaefolia (L.) R. Br. collected in Nicaragua was evaluated by GC and GC-MS. The main components were ( Z)-phytol (22.8%), caryophyllene oxide (18.9%) and hexahydrofarnesylacetone (9.0%). The antibacterial activity against several Gram + and Gram - bacteria, including Bacillus cereus and B. subtilis, both infesting historical cellulosic material, was also determined. B. cereus, B. subtilis and Staphylococcus epidermis were the most affected by the action of the oil.

Data Quality Model-Based Testing of Information Systems: Two-Level Testing of the Insurance System

2021

In order to develop reliable software, its operating must be verified for all possible cases of use. This can be achieved, at least partly, by means of a model-based testing (MBT), by establishing tests that check all conditions covered by the model. This paper presents a Data Quality Model-based Testing (DQMBT) using the data quality model (DQ-model) as a testing model. The DQ-model contains definitions and conditions for data objects to consider the data object as correct. The proposed testing approach allows complete testing of the conformity of the data to be entered and the data already stored in the database. The data to be entered shall be verified by means of predefined pre-conditio…
