Metal-rich carbon stars in the Sagittarius dwarf spheroidal galaxy
(2009)We present spectroscopic observations from the Spitzer Space Telescope of six carbon-rich asymptotic giant branch (AGB) stars in the Sagittarius dwarf spheroidal galaxy (Sgr dSph) and two foreground Galactic carbon stars. ... -
The Metallicity and Elemental Abundance Gradients of Simulated Galaxies, and their Environmental Dependence
(2017-11-11)The internal distribution of heavy elements, in particular the radial metallicity gradient, offers insight into the merging history of galaxies. Using our cosmological, chemodynamical simulations that include both detailed ... -
The metallicity and elemental abundance maps of kinematically atypical galaxies for constraining minor merger and accretion histories
(2019-03-06)Explaining the internal distribution and motions of stars and gas in galaxies is a key aspect in understanding their evolution. In previous work we identified five well-resolved galaxies with atypical kinematics from a ... -
Metallicity and Mean Age Across M,33
(Springer Nature, 2008) -
Metallicity distributions of elliptical galaxies and globular cluster systems - Absorption line strength gradients in elliptical galaxies
(1999)Gradients of absorption line indices are studied and mean stellar metallicities are estimated for 46 elliptical galaxies. The mean stellar metallicities range from [[Fe/H]] similar or equal to -0.8 to +0.2 and ellipticals ... -
Metallicity effect on type Ia supernovae and galactic and cosmic chemical evolution

The metallicity gradient as a tracer of history and structure : the Magellanic Clouds and M33 galaxies
(2009-11)Context. The stellar metallicity and its gradient place constraints on the formation and evolution of galaxies. Aims. This is a study of the metallicity gradient of the LMC, SMC and M33 galaxies derived from their asymptotic ... -
Metallicity gradients in disks : Do galaxies form inside-out?
(2012-04)Aims. We examine radial and vertical metallicity gradients using a suite of disk galaxy hydrodynamical simulations, supplemented with two classic chemical evolution approaches. We determine the rate of change of gradient ... -
The metallicity of CM Draconis

Metamemory for involuntary autobiographical memories and semantic mind‐pops in 5‐, 7‐ and 9‐year‐old children and young adults
(2022-05-21)In a cross‐sectional study, 5‐, 7‐, and 9‐year‐old‐children and adults (N = 144, 86 females, predominantly White U.K. sample of lower‐middle to middle‐class background) were interviewed about their experiences of involuntary ... -
Metamemory prediction accuracy for simple prospective and retrospective memory tasks in 5-year-old children
(2014-11-01)It is well documented that young children greatly overestimate their performance on tests of retrospective memory (RM), but the current investigation is the first to examine children’s prediction accuracy for prospective ... -
The Metaphysical Status of Tractarian Objects
(2001-10) -
The Metaphysics of Perception: Wilfrid Sellars, Perceptual Consciousness, and Critical Realism
(Routledge, 2007)A defence of the Causal Theory of Perception, defending and extending original insights deriving from Wilfrid Sellars and the american Critical Realists. The work defends a dual component theory of experience, arguing that ... -
The metaplace security model
(2011)As part of an ongoing project on the security of online games and virtual reality applications, we joined the open beta test of Metaplace, to carry out our own analysis of Metaplace's security mechanisms, and to observe ... -
The metaplace security model (transcript of discussion)
(2011)OK, so I'm Michael Roe, my new organisational affiliation is the University of Hertfordshire, and this talk is going to be about the beta test of the Metaplace, which was an online game that was in test a year or so ago. ... -
Metastasis-promoting anterior gradient 2 protein has a dimeric thioredoxin fold structure and a role in cell adhesion
(2013-03-11)Anterior gradient 2 (AGR2) is a normal endoplasmic reticulum protein that has two important abnormal functions, amphibian limb regeneration and human cancer metastasis promotion. These normal intracellular and abnormal ... -
Meteorological and land use controls on past and present hydro-geomorphic processes in the pre-alpine environment : an integrated lake-catchment study at the Petit Lac d'Annecy, France
(2003-11)A wide range of environmental records is integrated in order to reconstruct the mechanisms of flooding and sediment transport within the 170 km(2) Petit Lac catchment, Annecy, France, over time scales of 10(-1) to 10(2) ... -
Meteorological conditions and structures of atmospheric boundary layer in October 2004 over Pearl River Delta area
(2008-08)High-level concentrations of air pollutants usually occur in autumn and winter over Peal River Delta (PRD), China. Atmospheric boundary layer observations were carried out at Qingyuan, Panyu and Xinken in PRD in October ...
