Palladium and cobalt bimetallic catalysts supported on sulfated zirconia (PdCo/SZ), obtained from different precursors of Pd (nitrate and acetylacetonate), were prepared to study their influence on the selective reductio...

Porous ceramics are widely used in fields such as heat insulation, filtration, sound absorption, and catalysis due to their good chemical stability, as well as the high permeability and large specific surface area of por...

Railway transportation is the main artery of the national economy, developing towards high speed, heavy load, and complex application environments. The performance and service safety of critical load-bearing components o...

This study analyzed the lyrics of songs that respondents (N = 2060) reportedly cried over. We first characterized these lyrics by comparing them to those of popular chart music. We then examined relationships between lin...

O-methyl-N-ethoxycarbonylthiocarbamate, CH3CH2OC(O)N(H)C(S)OCH3 (I), and O-ethyl-N-ethoxycarbonylthiocarbamate, CH3CH2OC(O)N(H)(S)OCH2CH3 (II), were prepared by the addition reaction between CH3CH2OC(O)NCS and the corres...

Through the laser-wire coaxial additive manufacturing technology, laser melting deposition experiments of GH4169 superalloy under different offsets were carried out, and the effects of different offsets on the microstruc...

Este trabajo explora las expresiones online de violencia ejercida o padecida por las y los adolescentes de sectores populares marginalizados del Área Metropolitana de Buenos Aires. Desde una metodología cualitativa, se...

A través de este capítulo —elaborado colaborativamente entre distintas áreas de FLACSO Argentina2— se pone el foco en siete dimensiones claves de la autonomía física, económica y en la toma de decisiones de las...

Fil: Bondaruk, Viviana. Universidad de Buenos Aires. Facultad de Agronomía. Argentina. Los pronósticos de cambios en el clima predicen alteraciones en las precipitaciones, la temperatura y la frecuencia e intensidad de...

La cromatografía líquida de alta eficacia de fase invertida (CLAE-FI) ha sido ampliamente utilizada con propósitos analíticos y en la determinación de parámetros fisicoquímicos necesarios en el diseño de nuevas d...

Abstract We present the theoretical and technical foundations of the Amsterdam Density Functional (ADF) program with a survey of the characteristics of the code (numerical integration, density fitting for the Coulomb pot...

Molecular structure does not easily identify the intricate noncovalent interactions that govern many areas of biology and chemistry, including design of new materials and drugs. We develop an approach to detect noncovale...

The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations. Revisions are based on new structural data, empirical bond strengt...

Sobre la base de mediciones dieléctricas de soluciones muy diluidas de sulfametoxazol en etanol a 25 °C se calculó su momento dipolar (µ) utilizando la ecuación de Buckingham que resultó µ=11,61 D. El estudio teó...

Presented at the American Finance Association Meeting, New York, December 1973.

"El trabajo a continuación muestra el desarrollo de un proyecto de prefactibilidad respecto a la implementación de una línea de salazones secas premium de un frigorífico. Como salazón seca se comprendieron a los pro...

Docking studies of few substituted 5-benzyl-2, 4-thiazolidinedione moiety, which acts as peroxisome proliferator-activated receptor γ agonist was performed by using Glide v4.5. The docking studies reveal hydrogen bond f...

Este artículo presenta tres modelos macroeconómicos. El primero está basado sobre el modelo usado por el profesor Olivera en su artículo "La posición monetaria neta", publicado en esta revista, en el primer número ...

This paper uses an intertemporal general equilibrium asset pricing model to study the term structure of interest rates. In this model, anticipations, risk aversion, investment alternatives, and preferences about the timi...

New protein parameters are reported for the all-atom empirical energy function in the CHARMM program. The parameter evaluation was based on a self-consistent approach designed to achieve a balance between the internal (b...

Abstract The molecular structure hypothesis - that a molecule is a collection of atoms linked by a network of bonds - was forged in the crucible of nineteenth-century experimental chemistry and has continued to serve as ...

Examination of nature's favorite molecules reveals a striking preference for making carbon-heteroatom bonds over carbon-carbon bonds-surely no surprise given that carbon dioxide is nature's starting material and that mos...

Until recently, organoboronic acids have been of limited use in organic synthesis due to their low reactivity for ionic reactions. During the past two decades; however, it has become increasingly clear that they are valu...
