Análisis de la reconstrucción topográfica de superficies cónicas de revolución en función del desenfoque cuando se emplea la prueba de Hartmann para superficies convexas.
(2015-12)
Se implementa la prueba de Hartmann modificada en configuración telecéntrica, para la reconstrucción de superficies cónicas a partir de patrones de Hartmann tomados en diferentes posiciones axiales de la superficie de ...
TT¯ type deformation in the presence of a boundary
(Springer, 2018-08)
We continue the study of a recently proposed solvable irrelevant deformation of an AdS3/CFT2 correspondence that leads in the UV to a theory with Hagedorn spectrum. This can be thought of as a single trace analog of the ...
CFD-DEM modeling of solid motion in a water-calcium alginate fluidized column and its comparison with results from radioactive particle tracking
(Elsevier Science Sa, 2019-12)
The motion of calcium alginate spheres in a liquid-solid fluidized bed is examined by radioactive particle tracking (RPT) and simulated by computational fluid dynamics coupled with discrete element method (CFD-DEM). ...
Extension of the SAFT-VR Mie EoS To Model Homonuclear Rings and Its Parametrization Based on the Principle of Corresponding States
(2017)
The statistical associating fluid theory of variable range employing a Mie potential (SAFT-VR-Mie) proposed by Lafitte et al. (J. Chem Phys. 2013, 139, 154504) is one of the latest versions of the SAFT family. This particular ...
Rationally designed mimics of antioxidant manganoenzymes: Role of structural features in the quest for catalysts with catalase and superoxide dismutase activity
(Elsevier Science Sa, 2018-06)
Manganese catalases (MnCAT) and superoxide dismutases (MnSOD) deplete hydrogen peroxide and superoxide in cells through a ping-pong mechanism involving cyclic oxidation and reduction of the metal cofactor. In a variety of ...
Coordination of peroxide to the CuM center of peptidylglycine α-hydroxylating monooxygenase (PHM): Structural and computational study
(Springer, 2013-02)
Many bioactive peptides, such as hormones and neuropeptides, require amidation at the C terminus for their full biological activity. Peptidylglycine a-hydroxylating monooxygenase (PHM) performs the first step of the amidation ...
Differences in applied electrical power between full thorax models and limited-domain models for RF cardiac ablation
(Informa Healthcare, 2020-06-18)
Purpose: Most modeling studies on radiofrequency cardiac ablation (RFCA) are based on limited-domain models, which means the computational domain is restricted to a few centimeters of myocardium and blood around the active ...
Mecanismo de biossorção seletiva de arsênio (III) em rejeitos ricos em proteinas fibrosas
(Universidade Federal de Minas GeraisUFMG, 2004-09-03)
Based on biochemical and toxicological fundamentals that explain arsenic toxicity, a novel approach for the treatment of arsenic-containing waters was developed. The approach involved the use of an abundant cysteine-rich ...
Análise estrutural de complexos metálicos derivados do ácido 4-amino-2-hidroxibenzóico
(Universidade Federal de Minas GeraisUFMG, 2012-07-27)
In this work have been performed structural elucidation and electronic investigations of two new coordination complexes derived from the 4-amino-2-hidroxybenzoic acid, where the studied ions were Zn2+ and Cu2+. In these ...
