Quantum yield measurements by thermal lens in highly absorbing samples: The case of highly doped rhodamine B organic/silica xerogels
(2019-11-04)
In this work, rhodamine B-doped GPTS/TEOS-derived organic/silica monolithic xerogels were prepared by the predoping sol-gel process. Thermal lens method was applied to determine thermo-optical properties of the samples. ...
Sensitivity Enhancement of Piezoelectric Transducers for Impedance-Based Damage Detection via a Negative Capacitance Interface
(2020-12-01)
Piezoelectric transducers are used in many applications due to electromechanical coupling, which allows mechanical and electrical quantities to be related. This principle is used in the development of structural damage ...
HYPROP measurements of the unsaturated hydraulic properties of a carbonate rock sample
(2020-12-01)
The unsaturated hydraulic properties provide important theoretical and practical information about fluid flow in soils and rocks for a range of soil, environmental and engineering applications. In this study we used the ...
Defect induced room temperature ferromagnetism in high quality Co-doped ZnO bulk samples
(2021-04-05)
The nature of the often reported room temperature ferromagnetism in transition metal doped oxides is still a matter of huge debate. Herein we report on room temperature ferromagnetism in high quality Co-doped ZnO (Zn1−xCoxO) ...
Opacity from Loops in AdS
(2021-02-01)
We investigate how quantum dynamics affects the propagation of a scalar field in Lorentzian AdS. We work in momentum space, in which the propagator admits two spectral representations (denoted “conformal” and “momentum”) ...
Psychosociological Intervention: The Listening Construction and the Implication in Organizations
(2020-01-01)
Psychosociology offers a theoretical—methodological framework that is useful to the understanding and exploration of the relationships between the conflicts experienced in the current labor scenario, the suffering of the ...
Exploring innovative projects in museological communicationExploración sobre proyectos innovadores en comunicación museológicaExplorando projetos de inovação em comunicação museológica
(2021-01-01)
Information overload has caused marked changes in the way people seek information and, in turn, have reshaped society, especially in digital information environments such as libraries and museums. The aim of this study was ...
A look at the vestiges of historiography of philosophy in official documents and in the tradition of philosophy teacher's education
(Univ Federal Santa Maria, 2020-01-01)
The aim of this article is to point to the vestiges of an educational heritage that provides guidelines for the subject of Philosophy in basic education and also models Philosophy teachers' education. This reconstruction ...
Evolutionary advantages of turning points in human cooperative behaviour
(Public Library Science, 2021-02-09)
Cooperation is crucial to overcome some of the most pressing social challenges of our times, such as the spreading of infectious diseases, corruption and environmental conservation. Yet, how cooperation emerges and persists ...
VALIDATION OF INSTRUMENT ON MORAL ENGAGEMENT AND DISENGAGEMENT OF TEACHERS IN THE FACE OF BULLYING AT SCHOOL
(Univ Estadual Paulista-unesp, Fac Ciencias Letras Assis, 2021-01-01)
Although bullying occurs in parental relationships, its prevention and overcoming in school demand the intervention of teachers, who need to be able to bring students to the awareness of the moral content at stake in a ...
