Diseño y caracterización de un enfriador de átomos de tipo “desacelerador Zeeman”
(2016)
Nosotros presentamos un método que utiliza simultáneamente dos modelos matemáticos, con el objetivo de optimizar el diseño de un desacelerador Zeeman, con miras a la implementación de átomos ultrafríos a la física del ...
The Hubble Constant and the Deceleration Parameter in Anisotropic Cosmological Spaces of Petrov type D
(2016-11)
In this paper the Hubble parameter and the deceleration parameter are analyzed for a group of anisotropic homogeneous solutions of the Petrov type-D. It is obtained that for the said set of solutions can be constructed a ...
Monte Carlo dosimetry of a realistic multicellular model of follicular lymphoma in a context of radioimmunotherapy
(2020)
Purpose
Small-scale dosimetry studies generally consider an artificial environment where the tumors are spherical and the radionuclides are homogeneously biodistributed. However, tumor shapes are irregular and radiopharmaceutical ...
Observed Changes (1970-1999) in Extreme Hydroclimatic Events in Central America
(2018-04-20)
Previous studies have shown that most of Central America has been experiencing warming trends during the last 30-50 years, while precipitation annual totals have not changed much. Warming alone can exacerbate the effects ...
Revealing a new region of gamma-ray emission in the vicinity of HESS J1825–137
(2019-02-17)
HESS J1825–137 is a bright very high-energy gamma-ray source that has been firmly established as a pulsar wind nebula (PWN), and one of the most extended gamma-ray objects within this category. The progenitor supernova ...
Distribución espacial de impactos de eventos hidrometeorológicos en América Central
(2016)
América Central está expuesta a la ocurrencia de eventos hidrometeorológicos a lo largo del año y los impactos que estos pueden provocar van a estar mayormente localizados en áreas donde las variables tanto naturales como ...
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 ...
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: ...
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, ...
