Quantitative Schlieren Diagnostic Applied to a Nitrogen Thermal Plasma Jet
(Institute of Electrical and Electronics Engineers, 2019)
A quantitative interpretation of the schlieren technique applied to an atmospheric pressure, vortex-stabilized nitrogen thermal plasma jet generated in a direct-current nontransferred arc plasma torch (nitrogen gas flow ...
Measurement of atomic transition probabilities with laser-induced breakdown spectroscopy using the 3D Boltzmann plot method
(Pergamon-Elsevier Science Ltd, 2019-04)
This work presents a method for the determination of atomic transition probability of the emission lines of a given element using the 3D Boltzmann plot method. The method exploits the third (temporal) dimension of a classical ...
Local and effective temperatures of quantum driven systems
(American Physical Society, 2010-01)
We introduce thermometers to define the local temperature of an electronic system driven out of equilibrium by local ac fields. We also define the effective temperature in terms of a local fluctuation-dissipation relation. ...
Glycerine degradation by submerged plasma
(Iop Publishing Ltd, 2019-11-13)
Organic contaminants (for example in wastewater effluents) cause serious health and environmental problems due to their high chemical oxygen demand (COD), low biodegradability, and toxicity. Non-equilibrium and thermal ...
Thermal equilibrium of Nellore cattle in tropical conditions: an investigation of circadian pattern
(2018-05-01)
The aim of this work was to evaluate the diurnal patterns of physiological responses and the thermal regulation of adult Nellore bulls. Six 30-mo-old Nellore bulls (669 ± 65 kg BW) were randomly assigned to four 6-h periods ...
Local temperatures and heat flow in quantum driven systems
(American Physical Society, 2011-04)
We discuss the concept of local temperature for quantum systems driven out of equilibrium by ac pumps showing explicitly that it is the correct indicator for heat flow. We also show that its use allows for a generalization ...
Nonlocal effective actions in semiclassical gravity: Thermal effects in stationary geometries
(American Physical Society, 2017-11-08)
We compute the gravitational effective action by integrating out quantum matter fields in a weak gravitational field, using the Schwinger-Keldysh (in-in) formalism. We pay particular attention to the role of the initial ...
Formulações semiclássicas da mecânica quântica: uma análise do oscilador singular por meio do formalismo de Weyl-Wigner e trajetórias quânticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2020-02-10)
The usual quantum mechanics formalism does not address relevant points of the semiclassical limit. In this work two theoretical approaches will be considered: Bohmian mechanics and the Weyl-Wigner formulation. The singular ...
Active carpets drive non-equilibrium diffusion and enhanced molecular fluxes
(Nature, 2021)
Biological activity is often highly concentrated on surfaces, across the scales from molecular motors and ciliary arrays to sessile and motile organisms. These 'active carpets' locally inject energy into their surrounding ...
