Galaxy cluster mergers as triggers for the formation of jellyfish galaxies : case study of the A901/2 system
(2019) [Artigo de periódico]The A901/2 system is a rare case of galaxy cluster interaction, in which two galaxy clusters and two smaller groups are seen in route of collision with each other simultaneously. Within each of the four substructures, ... -
Galaxy populations in massive galaxy clusters to z = 1.1 : colour distribution, concentration, halo occupation number and red sequence fraction
(2017) [Artigo de periódico]We study the galaxy populations in 74 Sunyaev–Zeldovich effect selected clusters from the South Pole Telescope survey, which have been imaged in the science verification phase of the Dark Energy Survey. The sample extends ... -
Galaxy properties in different environments. II. Star formation in bulges of late-type spirals
(1994) [Artigo de periódico]The star formation history in the nucleus of late spiral galaxies is compared between a sample in a high galaxy density medium (HDS) and a control sample (CS) of isolated galaxies. We have observed 20 HDS and 18 CS galaxies ... -
Galaxy properties in different environments. I. The sample
(1994) [Artigo de periódico]This paper presents two galaxy samples, respectively in a high and in a low local density environments that were generated from the SSRS catalog using objective criteria. A preliminary comparison of physical properties in ... -
Galegos no sul do Brasil : alternativas na América
(2010) [Artigo de periódico]Este artigo aborda algumas alternativas profissionais que se apresentaram aos imigrantes galegos no sul do Brasil, particularmente na capital do estado do Rio Grande do Sul, Porto Alegre, em meados do século passado. Muitos ... -
Galerkin least-squares solutions for purely viscous flows of shear-thinning fluids and regularized yield stress fluids
(2007) [Artigo de periódico]This paper aims to present Galerkin Least-Squares approximations for flows of Bingham plastic fluids. These fluids are modeled using the Generalized Newtonian Liquid (GNL) constitutive equation. Their viscoplastic behavior ... -

Galinheiro Pedagógico um espaço de alfabetização científica no Clube de Ciências
(2021) [Artigo de periódico]Este artigo teve como objetivo verificar se as atividades desenvolvidas no Clube de Ciências a partir da realidade dos educandos contribuíram para uma aprendizagem significativa dos alunos do 3°, 4° e 5° anos de uma escola ... -
Gallai-Edmonds decomposition of unicyclic graphs from null space
(2022) [Artigo de periódico]In this paper, we compute the Gallai-Edmonds decomposition of a unicyclic graph G using linear algebraic tools. More precisely, the Gallai-Edmonds decomposition of G is obtained from the null space associated with adjacency ... -
Gallbladder protrusion through the groin region : a very unusual femoral hernia
(2019) [Artigo de periódico]Groin hernias are among the oldest recorded afflictions of mankind. Most of them protrude through the inguinal canal, and only a few through the femoral canal. Usually, they are present as a painful lump in the groin region, ... -
Gall-inducing insects of deciduous and semideciduous forests in Rio Grande do Sul State, Brazil
(2018) [Artigo de periódico]Galls are specific changes induced by insects on plant organs mainly through increases in plant cell number and/or size. Gall diversity is easy to recognize in the field because gallers are mostly species-specific, and ... -
Galling arthropod diversity in adjacent swamp forests and restinga vegetation in Rio Grande do Sul, Brazil
(2010) [Artigo de periódico]Galling arthropods create plant structures inside which they fi nd shelter. Factors acting on galler diversity are still being discussed, with this fauna considered more diverse in xeric than mesic environments (higrothermic ... -
Gallstones, body mass index, C-reactive protein, and gallbladder cancer: mendelian randomization analysis of chilean and european genotype data
(2021) [Artigo de periódico]Background and Aims: Gallbladder cancer (GBC) is a neglected disease with substantial geographical variability: Chile shows the highest incidence worldwide, while GBC is relatively rare in Europe. Here, we investigate the ... -

Galvanized steel pre-treated with hybrid film cured by UV : influence of photoinitiator concentration on the corrosion resistance
(2012) [Artigo de periódico]Several coatings have been proposed as an alternative to replacement processes based on hexavalent chromium. Among them stand out the hybrid films. Some hybrids films, with modified composition by the addition of ... -
Gambling as a teaching aid in the introductory physics laboratory
(1998) [Artigo de periódico]Dice throwing is used to illustrate relevant concepts of the statistical theory of uncertainties, in particular the meaning of a limiting distribution, the standard deviation, and the standard deviation of the mean. It is ... -
