A magnetic levitation control system is developed in this work. The non-linear system model is linearized around the operating point. Two control loops, an inner current loop and an outer position loop are designed using...

En el Grupo de Polímeros y Reactores de Polimerización del INTEC se ha realizado un trabajo de investigación detallado del proceso de obtención de látex híbridos acrílicos/caseína y su aplicación como recubrimie...

We obtain convolution inequalities in Lebesgue and Lorentz spaces with power weights when the functions involved are assumed to be radially symmetric. We also present applications of these results to inequalities for Rie...

El 14 de abril de 1922 nacía María Luisa Bemberg, directora de cine recordada por películas como Camila (1984), Miss Mary (1986) y Yo, la peor de todas (1990) y una de las fundadoras de la Unión Feminista Argentina. ...

Tesis de Doctorado El objetivo de esta tesis es analizar la construcción de un campo escultórico moderno en la ciudad de Buenos Aires entre 1882 y 1919. El interés de esta investigación es recuperar el lugar que los ...

A comprehensive structural, petrological, and geophysical study of the 385 ± 2 Ma Devonian El Hornito Pluton (EHP) in the Sierra Grande de San Luis, Argentina, is presented. We establish that the EHP results from the in...

In this work, we consider an agent-based model in order to study the wealth distribution problem where the interchange is determined with a symmetric zero-sum game. Simultaneously, the agents update their way of play try...

Given a standard myopic process in a coalition formation game, an absorbing set is a minimal collection of coalition structures that is never left once entered through this process. Absorbing sets are an important soluti...

A study was undertaken to ascertain the analytical capabilities of l-methionine immobilized on controlled pore glass for Sb preconcentration and speciation. A fully automated on-line system, implemented with hydride gene...

Yersinia enterocolitica is associated with human clinical manifestations. In this study, the bioserotype distribution, virulence potential, the antimicrobial susceptibility, and the genomic diversity of Y. enterocolitica...

The etiology of obesity is multifactorial, and includes genetic, environmental, and dietary factors, where hypercaloric diets play a central role in the development of the disease. It is known that obesity in adulthood c...

A series of Ni supported over MgAl2O4–CeO2 catalysts have been prepared by the wet impregnation method as catalysts for steam ethanol reforming. The synthesis was performed using nitrilotriacetic acid (NTA) or citric a...

En este trabajo se desarrolla una estrategia de control no lineal para un convertidor electrónico de potencia DC-DC reductor (convertidor buck) que alimenta una carga de potencia constante. Debido a la no linealidad que...

Several natural and synthetic coumarins were assayed against different cancer cell lines. Four of them have shown cytotoxicity against a panel of three human solid tumor cell lines (HeLa, T-47D, and WiDr) and a clearly a...

The deactivation of the H3PW12O40 (HPW) catalyst supported on TiO2 used in the isomerization reaction of α-pinene and its regeneration were studied. The regeneration of the deactivated catalyst was carried out with an a...

Dendritic cells (DCs) participate in the pathogenesis of several diseases. We investigated DCs and the connection between mucosa and joints in a murine model of Yersinia enterocolitica O:3-induced reactive arthritis (ReA...

An in silico analysis of the oxidation mechanism of allyl methyl disulfide (AMDS) by hydroxyl radical was achieved at DFT level using B3LYP, CAM-B3LYP, M06-2X, and BMK functionals and 6-311++G(3df,2p) triple-zeta basis s...

Progesterone (P4) is a steroidal hormone with a vital role in the maintenance of human and animal health. This paper describes the development of an immunosensor coupled to glassy carbon (GC) electrode and integrated to ...

Cu-Ni nano-alloys were prepared using precursors synthesized by the citrate-gel method. The effects of initial solution pH value and calcination temperature on the composition, crystalline structure, purity, morphology, ...

The renin-angiotensin system (RAS) has been implicated in pulmonary hypertension and pulmonary fibrosis. In the present study, we examined the effects of maternal exposure to captopril (2.85. mg/kg/day) during late pregn...

We study a particle system with the following diffusion-branching-selection mechanism. Particles perform independent one dimensional Brownian motions and on top of that, at a constant rate, a pair of particles is chosen ...

The purpose of this work is, first, to present a fast and accurate technique to compute Boltzmann-averaged values of the quantum-chemical 13C chemical shifts for each amino acid in oligopeptides, demonstrated here by an ...

The objective of this work was to develop a microfluidic immunosensor for the quantitative determination of IgG antibodies to Toxocara canis (IgG anti-T.canis), causal agent of toxocariasis. This disease is caused by acc...

Sistemas em aléias podem consistir numa solução para o uso da terra em regiões do Trópico Úmido. A relação dessa forma de manejo com a dinâmica dos fungos micorrízicos arbusculares (FMA) ainda é pouco compreen...
