Probing the origin of 4FGL J0822.8–4207: cosmic ray illumination from the SNR Puppis A and the Herbig-Haro object HH219
(2021)
4FGL J0822.8–4207 is a point source found in the 4FGL-DR2 catalogue by the gamma-ray observatory Fermi-LAT and has no known association. We carry out X-ray observations of 4FGL J0822.8–4207 to help understand its nature. ...
Implementation of patient dosimetry in the clinical practice after targeted radiotherapy using [177Lu-[DOTATO,Tyr3]-octreotate
(2018-11-29)
Background: This study’s aim was to develop our dosimetric methodology using a commercial workstation for the
routine evaluation of the organs at risk during peptide receptor radionuclide therapy (PRRT) with 177Lu.
Methods: ...
Relation between Luminescence and Electronic Surface Characteristics in p-type Porous Silicon
(1997)
Measurements of photoluminescence, electronic surface states and effective surface area, at various stages of the anodization process, are presented. The results show a behavior different from that observed on n-type porous Si.
Exact solution of an ekpyrotic fluid and a primordial magnetic field in an anisotropic cosmological space-time of Petrov D
(2017)
This document obtained and analyzed an exact solution of an ekpyrotic fluid (P = 5/3 µ) and a primordial magnetic field, so that the latter does not induce currents or electric fields. It is determined that the main role, ...
Lamellar fluctuations melt ferroelectricity
(2023)
We consider a standard Ginzburg-Landau model of a ferroelectric whose electrical polarization
is coupled to gradients of elastic strain [1–4]. At the harmonic level, such flexoelectric interaction
is known to hybridize ...
Propuesta de estrategias metodológicas para el contenido curricular “Oscilaciones y ondas mecánicas” que propicie el aprendizaje significativo en el estudiantado que asiste al curso Laboratorio de Física General II de la Universidad de Costa Rica, Sede de Occidente durante el II semestre del 2020
(2020)
El presente trabajo tiene por objetivo general el proponer estrategias metodológicas para el contenido curricular “Oscilaciones y ondas mecánicas” que propicien un aprendizaje significativo en el estudiantado que asiste ...
Converging science and literature cultures: learning physics via The Little Prince novella
(2018)
Primary level education follows a pedagogy model where literature and science have been historically separated. Natural children processes are disrupted, as learning based on play curiosity is completely transformed by a ...
Ozonesonde Quality Assurance: The JOSIE–SHADOZ (2017) Experience
(2019)
The ozonesonde is a small balloon-borne instrument that is attached to a standard radiosonde to measure profiles of ozone from the surface to 35 km with ∼100-m vertical resolution. Ozonesonde data constitute a mainstay of ...
Exact Solutions of a Chaplygin Gas in an Anisotropic Space-Time of Petrov D
(2017)
This document obtains two exact solutions to the anisotropic spacetime of Petrov D by using the model of a perfect fluid. These solutions represent a scenario of a universe in which the pressure P and the energetic density ...
Energy exchange between atoms with a quartz crystal μ-balance
(2018)
We propose an experimental method to fully characterize the energy exchange of particles during the
physical vapor deposition (PVD) process of thin surface layers. Our approach is based on the careful
observation of ...
