Sémiotique des interfaces : la promesse du flat design
2015
International audience; Popularisé par l'informatique, le concept d'interface a connu une extension considérable dans le domaine des sciences de la communication où il désigne tout dispositif favorisant l'échange et l'interaction entre différents actants (personnes, systèmes, objets, etc.) ; l'interface 1 n'est rien d'autre, en fait, que la face opérationnelle du canal de Shannon, le passage obligé de tout processus de communication et particulièrement de médiation puisqu'il s'agit alors d'introduire de la continuité entre deux systèmes aux propriétés différentes, de briser cette frontière commune à deux domaines : plus les éléments à apparier sont hétérogènes ou complexes, plus le rôle de …
Photoinduced Electron Transfer in a Porphyrin-Fullerene Dyad at a Liquid Interface
2022
The excited-state properties of an amphiphilic porphyrin–fullerene dyad and of its porphyrin analogue adsorbed at the dodecane/water interface are investigated by using surface second-harmonic generation. Although the porphyrin is formally centrosymmetric, the second-harmonic spectra of both compounds are dominated by the intense Soret band of the porphyrin. Polarization-selective measurements and molecular dynamics simulations suggest an angle of about 45° between the donor–acceptor axis and the interfacial plane, with the porphyrin interacting mostly with the nonpolar phase. Time-resolved measurements reveal a marked concentration dependence of the dynamics of both compounds upon Q-band e…
Gas-Phase Hydrogenation of Propionitrile Catalyzed by LnCu2 (Ln = La, Ce, Pr, Nd)
2007
The hydrogenation of propionitrile over binary copper−lanthanide intermetallic compounds (LnCu2, Ln = La, Ce, Pr, Nd) was studied in the gas phase. The results show that the reaction main product is the primary amine, the n-propylamine. To our knowledge, it is the first time that such behavior is reported for copper catalysts.
Age-Related Differences in Intermuscular Coherence EMG-EMG of Ankle Joint Antagonist Muscle Activity during Maximal Leaning
2022
Background: Intermuscular synchronization is one of the fundamental aspects of maintaining a stable posture and is of great importance in the aging process. This study aimed to assess muscle synchronization and postural stabilizer asymmetry during quiet standing and the limits of stability using wavelet analysis. Intermuscular synchrony and antagonistic sEMG-sEMG (surface electromyography) coherence asymmetry were evaluated in the tibialis anterior and soleus muscles. Methods: The study involved 20 elderly (aged 65 ± 3.6) and 20 young (aged 21 ± 1.3) subjects. The task was to perform a maximum forward bend in a standing position. The prone test was divided into three phases: quiet standing …
Sposoby vyraženiâ položitelʹnyh èmocij v Internete
2021
The Internet as a new means of communication promotes the emergence of new ways of expressing thoughts and emotions. Our brief analysis of the techniques for verbalizing positive emotions on the Internet shows that Internet users have found ways to solve these problems. The graphic and lexical means they use allow them to express the entire range of experiences. Prolongation and chanting replace phonetic means, emoticons convey facial expressions, duplicated punctuation marks express the power of emotions. The statements of Internet users are characterized by brevity, because saving time is also one of the features of communication in the virtual space. It should be noted, however, that thi…
Free school meals as an opportunity to target social equality, healthy eating, and school functioning: experiences from students and teachers in Norw…
2021
Background There are no national arrangements for free school meals provision in Norway despite this being an important opportunity to improve children's and adolescents' nutritional status and ultimately their physical and cognitive development. During a one academic year (2014-2015), a group of Norwegian sixth graders were served a free healthy school meal in a project called 'The School Meal Project'. Objective To explore students' and teachers' experiences of receiving free school meals after the free school meal in 2015 and 5 years later. Design In-depth, semi-structured interviews with separate groups in 2015 and in 2020 were conducted face to face or via telephone or digital platform…
Progress in Understanding of the Interactions between Functionalized Polyolefins and Organo-Layered Double Hydroxides
2014
The dispersion of organo-layered double hydroxides (O-LDH) in functionalized polyolefins (POs) is investigated. Two different polyethylene matrices (maleic anhydride (MAH) and diethyl maleate functionalized) are tested and a hydrogenated fatty acid modified LDH is used. The attention is focused on evidencing the interaction between the functional groups of the polymer and the O-LDH through FT-IR. Moreover, a combination of solvent fractionation, morphological, and rheological characterizations enables to gain a deeper insight into the structure of these composites. In particular, the formation of bridging bonds between the particles and MAH functionalized macromolecules is assumed, possibly…
Reproducibility of irritant patch test reactions to sodium lauryl sulfate in a double-blind placebo-controlled randomized study using clinical scorin…
1999
Reading of doubtful patch test reactions can be improved by comparing them to defined negative, allergic and irritant controls. For the latter, an irritant patch test is needed that gives sufficiently reproducible results. In our double-blind, placebo-controlled. randomized study, we have analysed the synchronous reproducibility of patch tests with 0%, 0.0625%, 0.125%, 0.25%, 0.5% and 1.0% sodium lauryl sulfate (SLS). Tests and readings were done according to ESCD guidelines. 139 patients (75 women, 64 men) 18 to 77 years old were tested. The % of positive patients as well as the % of reproducible positive reactions increased with rising concentrations of SLS to a maximum of approximately 9…
Seju aizsedzoša reliģiska apģērba nēsāšanas aizlieguma juridiskie aspekti
2018
Maģistra darba nosaukums ir ’’Seju aizsedzoša reliģiska apģērba nēsāšanas aizlieguma juridiskie aspekti’’. Paredzot aizliegumu publiskās vietās nēsāt seju aizsedzošu apģērbu, var tikt ierobežotas personas tiesības uz reliģijas brīvības ārējo izpausmi, jo reliģijas brīvības ārējā izpausme ietver arī galvassegu nēsāšanu, kas it sevišķi ir attiecināms uz musulmaņu sievietēm. Šobrīd Latvijā tiek izstrādāts likums, ar kuru tiek plānots aizliegt publiskās vietās nēsāt seju aizsedzošu apģērbu. Tādējādi ir nepieciešams apzināt, izpētīt un izvērtēt tos juridiskos aspektus saskaņā ar kuriem šāds ierobežojums būtu atzīstams par tiesisku. Maģistra darba mērķis ir to juridisko aspektu noskaidrošana un i…
