Dose point kernel calculation and modelling with nuclear medicine dosimetry purposes
(2014)
Monoclonal labeled antibodies are commonly used for radioimmunotherapy purposes in nuclear medicine. The procedure is based on the deposition of specific radiactivity concentrations on tumoral regions with the aim of ...
Construction of a quartz spherical analyzer : application to high-resolution analysis of the Ni Ka emission spectrum
(2016)
The construction and characterization of a focusing X-ray spherical analyzer based on α-quartz 4404 are presented. The performance of the analyzer was demonstrated by applying it to a high-resolution X-ray spectroscopy ...
Solid-state studies of the crystalline/amorphous character in linear Poly(ethylenimine hydrochloride) (PEI-HCl) polymers and their copper complexes
(2015)
Linear poly(ethylenimine hydrochloride) (PEI-HCl) polymers with different molecular weights (22, 87, and 217 kDa) and their copper complexes (Cu−PEI) were studied with particular attention to the crystalline/amorphous ...
Some totally geodesic submanifolds of the nonlinear Grassmannian of a compact symmetric space
(2014)
Let M and N be two connected smooth manifolds, where M is compact and oriented and N is Riemannian. Let E be the Fréchet manifold of all embeddings of M in N, endowed with the canonical weak Riemannian metric. Let ∼ be the ...
Dosimetry optimization system and integrated software (DOSIS) : a comparison against Fluka code results over a standard phantom
(2014)
Actually, dual-imaging facilities allow obtainance of both mass and activity patient-specific distributions perfectly correlated, which are important to improve dose distributions estimations and radioimmunotherapy treatment ...
Experimental determination of <10 10>/ Ψ tilt grain boundary energies in ice
(2014)
Ice grain boundary energies γgb relative to the free surface energy γs were determined by studying the topographic details revealed by plastic replicas of the ice grain boundary groove-free surface with a Laser Confocal ...
Strictly positive solutions for one dimensional nonlinear elliptic problems
(2014)
We study the existence and nonexistence of strictly positive solutions for the elliptic problems -- in a bounded open interval, with zero boundary conditions, where -- is a strongly uniformly elliptic differential operator, ...
Weighted inequalities for some integral operators with rough kernels
(2014)
In this paper we study integral operators with kernels K(x, y) = k1(x − A1y)...km(x − Amy), ki(x) = Ωi(x)
|x|n/qi where Ωi : Rn → R are homogeneous functions of degree zero, satisfying a size and a Dini condition, Ai are ...
ICME international survey on teachers working and learning through collaboration : June 2016
(2016)
This article presents preliminary results from a survey commissioned for ICME 13 (2016) focusing on “Teachers Working and Learning Through Collaboration”. It takes as a starting point a previous survey, commissioned for ...
Argentinean national presentation
(2017)
In this text, we aim to offer a brief overview of mathematics education (ME) in Argentina and the contributions that converge to its present. It includes four topics: the characteristics of the current education system and ...
