Random Electric Field Instabilities of Relaxor Ferroelectrics
(2017-06-13)
Relaxor ferroelectrics are complex oxide materials which are rather unique to study the effects of compositional disorder on phase transitions. Here, we study the effects of quenched cubic random electric fields on the ...
Física y Poesía: T.S. Eliot
(1992)
Tres poemas de T.S. ELIOT, publicados en 1989, sugieren que el autor tenía conocimientos tanto de física clásica como de física moderna.
En este artículo se describen los conceptos físicos tratados y se hace referencia ...
A study of a coronal hole associated with a large filament eruption
(2017)
We report the results of a detailed study of an equatorial coronal hole and a dimming region related to the eruptions of a nearby large filament and subsequent coronal mass ejections (CMEs). The dynamic eruptions of the ...
Large isotropic negative thermal expansion above a structural quantum phase transition
(2015-10-01)
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of energy solutions. An always-contributing ...
QA Programme of the TLD laboratory of the University of Costa Rica: IEC 61066 testing
(2008)
The Thermoluminescence Personal Dosimetry Laboratory of the University of Costa Rica provides dose measurements for around 90% of occupational radiation workers in the country. The assessment of doses to workers routinely ...
Evaluation of [18F] FNM biodistribution and dosimetry based on whole-body PET imaging of rats
(2018)
Introduction: The aim of this work was to study the biodistribution, metabolism and radiation dosimetry of rats
injected with [18F]FNM using PET/CT images. This novel radiotracer targeting NMDA receptor has potential ...
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: ...
Biological and dosimetric evaluation of [11C]S-adenosyl methionine as a potential agent for prostate cancer diagnosis
(2018)
Introduction: [11C]Choline ([11C]COL) has been widely used for prostate cancer diagnosis; however, this
radiopharmaceutical is not recommended for patients with a low absolute PSA value (< 1 ng/mL) due to its
limited ...
Informe Final: Articulación de un sistema de identificación de locutor con fines forenses
(2016-02-29)
La investigación tiene que ver con la identificación automatizada de locutor (Voice ID) con fines forenses (lo cual convierte a este proyecto en un trabajo de fuerte aplicación en temas de sociedad). El objetivo general ...
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, ...
