To determine the pharmacologic activity of (-)-lobeline between human (h)α4β2 and hα4β4 nicotinic acetylcholine receptors (AChRs), functional and structural experiments were performed. The Ca2+ influx results establi...

Integral field spectroscopy obtained with the Potsdam Multi-Aperture Spectrophotometer Fiber Package (PPak) and the 3.5-m telescope at the Calar Alto Observatory has been used to study an outer H II region complex in the...

Studies of reproductive biology are essential to understanding the life history of species and contribute to determining their conservation status and future protection. The Andean Gecko (Homonota andicola) is a small li...

This study investigates the properties of a composite material obtained by mixing Fe78Si9B13 metallic powders (at %) with graphene nanoplates (GNP) in an epoxy matrix. Four composite types were created with GNP weight pr...

A robust, simple and fast procedure for the calculation of uncertainties in static relative permittivity (ε s ) computed via molecular dynamics (MD) is proposed. It arises as a direct application of well founded statist...

Capybaras (Hydrochoerus hydrochaeris) have been used in Argentina since pre-Columbian times as a source of hide, meat, and fat. Hide is the most valuable capybara by-product and, at present, represents the major hunting ...

Resumo Não faz maior sentido perder-se em discussões sobre ser ou não inacabada a realização de Hélio Oiticica rodada na Wall Street de 1972 levando-se em conta o filme que temos visto desde 1992 (em quase todas as...

In three departments of the Corrientes province, the performance of 6 seeders was evaluated during corn sowing at three different speeds for each machine. A randomized complete block design was used with nested treatment...

Analisando a resenha de Carlos Nelson F. Santos a respeito de meu livro Urbanização e Mudança Social no Brasil, tive a sensação de que o resenhador se frustrou por eu não ter escrito o livro que ele gostaria de ter...

En este trabajo se presenta una herramienta informática original que permite realizar análisis de consistencia interna (modelo Alfa de Cronbach) utilizando métodos gráficos dinámicos. Se trata de un módulo basado e...

The measures of the semantic relatedness of concepts can be categorised into two types: knowledge‑based methods and corpus‑based methods. Knowledge‑based techniques make use of man‑created dictionaries, thesaurus...

From 2008 to 2011, several planned modifications were implemented at the RA-6 reactor in Argentina, leading to significant benefits for future BNCT treatments. New capabilities have been implemented in NCTPlan treatment ...

Dynamic fault trees (DFTs) are widely adopted in industry to assess the dependability of safety-critical equipment. Since many systems are too large to be studied numerically, DFTs dependability is often analysed using M...

Em novembro de 2012, o Laboratório de Indigenismo e Etnologia (Linde) do Departamento de Antropologia da Universidade de Brasília organizou o seminário Aprofundando a Amazônia: Contribuições da Arqueologia à Etn...

We have developed three methods for the automatic picking of first breaks that can be used for marine, dynamite, or vibroseis shot records: a modified Coppens´s method, an entropy-based method, and a variogram fractal-d...

We have analyzed the frequency and properties of the nuclear activity in a sample of galaxies with circumnuclear rings and spirals (CNRs), compiled from published data. From the properties of this sample a typical circum...

The demographic characteristics of marine zooplankton make it especially suitable for examining the variability of marine ecosystems. The zooplankton annual succession was studied at a permanent coastal station in the Ar...

We studied the seismic attenuation and velocity dispersion effects produced by wave-induced fluid flow in weakly consolidated sandstones containing patchy carbon dioxide CO ð Þ2 -brine distributions. The analysis also ...

We provide a checklist of angiosperms collected in the Paraná River Delta Region during the 1990s and early 2000s. Plants were taxonomically identified and classified according to their origin (native/endemic and exotic...
