The study of calcium signaling in lipid gustatory cells in mice
2012
The lipid-binding glycoprotein CD36, expressed by circumvallate papillae (CVP) of the mouse tongue, has been shown to be implicated in oro-gustatory perception of dietary lipids. We demonstrate that linoleic acid (LA) by activating sPLA2, cPLA2 and iPLA2 via CD36, produced arachidonic acid (AA) and lyso-phosphatidylcholine (Lyso-PC) which triggered Ca2+ influx in CD36-positive taste bud cells (TBC), purified from mouse CVP. LA induced the production of Ca2+ influx factor (CIF). CIF, AA and Lyso-PC exerted different actions on the opening of store-operated Ca2+ (SOC) channels, constituted of Orai proteins and regulated by STIM1, a sensor of Ca2+ depletion in the endoplasmic reticulum. We use…
Gustatory evoked cortical activity in humans in response to saccharin stimuli
2014
National audience; Introduction/Objectives: Gustatory Evoked Potentials (GEP) can be detected in response to an intermittent stimulation of the gustatory receptors by a primary flavour. Contrary the other evoked cortical potentials (visual, auditory or sensory), GEP have not been extensively studied due to their recording heterogeneity. Our aim was to establish a reliable recording of GEP in Humans. Methods: Voluntary and healthy subjects were included in this experiment. A saccharin solution with several concentrations (5, 10 or 20g per 100mL) was used as the gustatory stimulus. Each session was performed on a different day, with an interval of at least 2 hours after eating or drinking. Co…
Characterization of the ligands for the human umami taste receptor
2017
National audience; Among our basics senses, taste and our gustatory system allow us to perceive and recognize essential chemical nutrients present in food. Human can detect and discriminate five basics taste (sweet, bitter, sour, salty and umami) and recent studies proposed a sixth taste for fat. The umami taste is described as a « savory » sensation elicited mainly by L-amino acids and is thought to serve as an indicator of protein rich foods and promote feeding.The umami taste receptor is a heterodimeric receptor composed of the T1R1 and T1R3 subunits. These subunits belong to the family class C G protein-coupled receptors (GPCRs) and are constituted by a large N-terminal domain (NTD) lin…

Sensorless control of permanent magnet synchronous motors for wide speed range applications
2006
This paper deals with sensorless control of Interior Permanent Magnet Synchronous Motors (IPMS) based on the estimation of speed and rotor angular position. The above estimate is based on the injection of high frequency stator currents able to generate a signal similar to that generated by a resolver connected to the axis of the motor. A new digital algorithm has been designed to demodulate the above signal whose implementation can be carried out on the same DSP that processes the control algorithm. In this paper a new scheme of speed and angular position estimator is proposed and justified on the theoretic point of view. The experimental results here shown validate the effectiveness of the…
Operazioni di pagamento tramite wallet e responsabilità da omessa applicazione della strong customer authentication
2022
Lo scritto commenta una recente decisione del Collegio di Coordinamento ABF a proposito del riparto di responsabilità tra intermediario emittente una carta di pagamento e cliente, in caso di operazioni abusivamente realizzate da terzi tramite «wallet». Il Collegio, analizzando la disciplina in tema di servizi di pagamento elettronici e di « Strong Customer Authentication », precisa come l’indagine del caso vada in primo luogo condotta verificando che l’intermediario abbia fornito la prova della corretta applicazione dell’autenticazione forte in ogni fase delle transazioni abusivamente compiute. Ove tale prova non sia fornita, egli dovrà restituire quanto dal cliente abusivamente versato. Th…
A New Solution for Sea Wave Energy Harvesting, the Proposal of an Ironless Linear Generator
2020
The paper investigates an innovative ironless linear generator, installable inside a wave energy converter, in order to produce electricity from sea waves. This energy source is considered strategic for the future, especially in small islands
A novel improved matlab-based software for the electric and magnetic analysis and design of rotating electrical machines
2015
The aim of this paper is to present a software for the analysis and design of windings of rotating electrical machines, considering both the electric and the magnetic specifications on the machine. The considered machines are induction motors (IM) and PM synchronous motors (PMSM). The software accounts for the case of buried magnets (IPMSM), but with some limits, because the calculations require a much more detailed analysis regarding the magnetic circuit. However, this initial limitation of the software, that will be removed in a later version, does not constitute a major limitation as confirmed by the examples presented in this paper.
Neatņemamās daļas tiesīgā atstumšana no mantojuma.
2017
Bakalaura darbs ir veltīts neatņemamās daļas tiesīgo institūtam un to atstumšanai no mantojuma. Neapšaubāmi, līdz šīm, Latvijas tiesību zinātnieki ir veltījuši uzmanību šim institūtam, vairākkārt izskatījuši ar to saistītos problēmjautājumus, piedavājot iespējamos risinājumus, no kuriem daži tika arī ieviesti, modernizējot Civillikuma mantojuma tiesību daļu. Darba mērķis ir izpētīt neatņemamās daļas tiesīgo atstumšanas institūtu, salīdzinot Latvijas un citu valstu tiesiskos regulējumus, un izvirzīt pilnveidošanas un uzlabošanas priekšlikumus Latvijas regulējumam. Pētījuma rezultatā, izvērtējot konkrētas materiālo tiesību normas, tiek secināts, ka Civillikuma mantojuma tiesību daļā pastāv pr…
