Interaction of the n-terminal domain of human t1r2 taste receptor with brazzein, a sweet-tasting protein
2015
Brazzein is a small (6.5 kDa) sweet-tasting protein originating from the fruit of Pentadiplandra brazzeana, a plant found in West Africa. Brazzein like all classes of sweet compounds is perceived through the activation of the T1R2/T1R3 heterodimeric sweet-taste receptor. T1R2 and T1R3 subunits are members of the small family of class C G-protein coupled receptors (GPCRs). Class C GPCRs possess a large N-terminal domain (NTD) linked to seven transmembrane domain by a cysteine rich domain (CRD). The NTD of T1R2 (T1R2-NTD) has been shown to contain the primary binding site for most of the sweet ligands. However, brazzein has been shown to require CRD of human T1R3 for receptor activation [1]. …
T@sty: a test for assessing taste sensitivity. Description, application example
2019
The aim of the poster is to present the T@styTM device and to give an example application through results obtained in an ongoing study. The advantages and limits of this device will be discussed. T@styTM device, usable for home testing, was designed to assess human ability to detect several tastants at low concentrations in order to provide individual profiles based on sensitivity to the five tastes (sweet, salty, sour, bitter, and umami). Three test-sheets made of edible paper are used for each taste (three replicate measurements). Each test-sheet consists of six series of three precut discs (one “tasty disc” and two neutral discs) on which taste stimuli of different intensities were depos…
Taste perception: from molecule to eating behaviour
2020
The sense of taste has a role in human nutrition, it help to orient our food choices and avoid the ingestion of toxi compounds. Advances in molecular biology, cell biology an, biochemistry were used to identify and characterize the main taste receptors. The identification of these receptors allow a better understanding of the physiological processes tha govern taste perception. The presence of genetic polymorphisr in these receptors explains interindividual differences in tast perception.
Evaluer un dispositif de formation à distance : Principes et retour d'expérience
2008
The multiplication of distance learning platforms and the complexity of some of those used within the university system raise questions. First of all, the stabilization of writing practices of digital documents. Secondly, the evaluation of these devices. We want to address this last point in this article. What is it possible to assess in this field? There are many dimensions of evaluation, depending on the angle chosen. We limit ourselves to an approach focused on evaluating the human-computer interface. The chosen testing ground is a website for law studies, developed by the University of Burgundy's further education section.
Mehr als Musik: Die sieben Dimensionen des Eurovision Song Contests
2008
"Der Eurovision Song Contest (ESC) ist der weltweit größte internationale Wettbewerb für populäre Musik und das erfolgreichste Fernsehunterhaltungsprogramm in Europa. Obwohl der ESC ursprünglich das Ziel verfolgte, die Entstehung neuer Lieder zu fördern, handelte es sich doch stets um ein von den Fernsehanstalten inszeniertes Medienereignis, das erst nachrangig musikökonomischen Zwecken dient. Für das Publikum ist der ESC auf Grund seiner Periodizität, seiner spezifischen Programmstruktur und nicht zuletzt des Zugehörigkeitsgefühls der Zuschauer, das auf Schemata nationaler und kultureller Identifikation beruht, zu einem hochgradig ritualisierten Medienereignis geworden. Seine Bedeutung geh…
Sensory testing in new product development: working with children
2015
Abstract This chapter aims at briefly reviewing applications of sensory descriptive testing methods with children, as well as their limits in relation to the cognitive development of children. Children’s sensory perceptions and preferences may differ from those of adults, which may make working directly with children a must for successful product development, at least at some stages of product development. However, most reported studies with children have characterized their preferences. Some studies have used discrimination tests and ranking tasks to gain knowledge about differences among products, or about sensory abilities development. A much smaller number of studies have involved child…

Radio studijas vadības sistēmas konfigurācijas saskarņu testu automatizācija
2017
Darba gaitā tika izstrādāta programmatūra radio studijas vadības sistēmas konfigurācijas lietotāja saskarņu testēšanai. Darba mērķis ir ievērojami atvieglot testētāju ikdienu, automatizējot viņu darbu un tādējādi ļaujot ietaupīt laiku, kas nepieciešams, lai notestētu, vai programmatūra darbojas tā, kā tai ir paredzēts. Pašreiz testēšana pārsvarā notiek tikai manuāli, kas ir ļoti apgrūtinoši un laikietilpīgi. Testu automatizācija ļauj to pašu darbu paveikt ievērojami ātrāk un ir krietni mazāk pakļauta kļūdām, kuras neizbēgami rodas cilvēciskā faktora rezultātā. Darba izstrādē tika izmantota speciāli šīs programmatūras testēšanai izstrādāta skriptu programmēšanas valoda.

The research on the amount and the types of corrective feedback beneficial for learning a second or foreign language has produced inconsistent results. Interestingly, studying corrective feedback from the perspective of a sociocultural theory of learning has the potential to resolve these differences although so far, these studies have been largely qualitative. The present study attempts to contribute to the existing research on corrective feedback from this perspective by comparing the effects of two types of automated corrective feedback on learning: adaptive feedback (i.e., feedback incrementally adapting to learners’ abilities by becoming more explicit and detailed) and knowledge of res…
