O Espaço para a Argumentação no Ensino Superior de Química

Educación Química, 2018
En este número especial, la sección DE ANIVERSARIO toma un tema novedoso de la enseñanza. Aunque haya profesores que lo hayan cultivado desde hace décadas, está de moda en las revistas de investigación educativa de las ciencias el publicar artículos con ...

Vertical Electric-Field-Induced Switching from Strong to Asymmetric Strong–Weak Confinement in GaAs Cone-Shell Quantum Dots Using Transparent Al-Doped ZnO Gates

Nanomaterials
The first part of this work evaluates Al-doped ZnO (AZO) as an optically transparent top-gate material for studies on semiconductor quantum dots. In comparison with conventional Ti gates, samples with AZO gates demonstrate a more than three times higher ...

Determination of Self-Heating in Silicon Photomultipliers

Sensors
The main consequence of radiation damage on a silicon photomultiplier (SiPM) is a significant increase in the dark current. If the SiPM is not adequately cooled, the power dissipation causes it to heat up, which alters its performance parameters.

Age-Related Response Bias in the Decoding of Sad Facial Expressions

Behavioral Sciences, 2015
Recent studies have found that age is negatively associated with the accuracy of decoding emotional facial expressions; this effect of age was found for actors as well as for raters.

Correcting the Non-Linear Response of Silicon Photomultipliers

Sensors
The finite number of pixels in a silicon photomultiplier (SiPM) limits its dynamic range to light pulses up to typically 80% of the total number of pixels in a device.

Spectral properties and breathing dynamics of a few-body Bose–Bose mixture in a 1D harmonic trap

New Journal of Physics, 2018
We investigate a few-body mixture of two bosonic components, each consisting of two particles confined in a quasi one-dimensional harmonic trap. By means of exact diagonalization with a correlated basis approach we obtain the low-energy spectrum and ...

ETUDE ET CONCEPTION DES CHAUSSEES NON REVETUES

, 2022
L'importance des routes en tant que système de transport ne saurait être surestimée car il s'agit du moyen de transport le plus utilisé au monde. Ce mémoire donne un aperçu de la façon dont les routes de gravier sont conçues et réalisées ainsi que certaines des difficultés rencontrées dans leur entretien.

CARACTERISATION GEOTECHNIQUE DU SABLE SILTEUX UTILISE EN COUCHE DE CHAUSSEE AU SUD DU TOGO ET DU BENIN

Journal de la Recherche Scientifique de l’Université de Lomé, 2016
Le sable silteux ou limoneux n’est pas un matériau conventionnel en géotechnique routière en zone tropicale comparativement à la latérite, la grave concassée, etc. Le présent travail a pour objectif de déterminer les performances mécaniques en termes de portance CBR, de résistance en compression et en traction des sables silteux du Togo et du Benin ...
