On authority and revocation : Climacus as humorist
(Rodopi, 2000)
The morphology of the Magellanic Clouds revealed by stars of different age: results from the DENIS survey
(2000)
The spatial distribution of sources populating different regions of the colour–magnitude diagram (I −J,I) extracted from the DENIS catalogue towards the Mag- ellanic Clouds (DCMC – Cioni et al. 2000) reveal signifi- cantly ...
Abundances in very metal-poor stars
(Institut d'Astrophysique et de Geophysique, 2000)
Metal-poor stars provide information on the characteristics and chemical evolution of the halo population of the Galaxy, the first epoch of star formation and Galaxy formation (not just locally but with relevance to ...
Retirement, Household Income, and Economic Vulnerability of Older Groups
(University of Hertfordshire, 2000)
This paper examines retirement behaviour and household income for older persons in Chile. It pays close attention to the sources of household income, income inequalities, and the economic vulnerability of older persons. ...
Primordial Lithium and Big Bang Nucleosynthesis
(2000)
Recent determinations of the abundance of the light-element Li in very metal-poor stars show that its intrinsic dispersion is essentially zero and that the random error in the estimated mean Li abundance is negligible. ...
VLBI observations of two single dMe stars: spatial resolution and astrometry
(2000)
We report on 3.6 cm VLA and VLBA observations of YZ CMi and AD Leo, two nearby dMe stars. We resolve YZ CMi and can fit a circular symmetrical gaussian component of FWHP of 0.98 0.2 mas, corresponding to an extent of the ...
First VLT spectra of white dwarfs in a globular cluster
(2000)
We present the first spectra obtained with the Very Large Telescope for white dwarfs in a globular cluster. Estimates of atmospheric parameters are obtained and compared to evolutionary tracks. We discuss possible implications ...
High Circular Polarization in the Star Forming Region NGC 6334: Implications
(Astronomical Society of the Pacific, 2000)
The amino-acids which form the building blocks of biological proteins are all left-handed molecules. By contrast, when these molecules are made in the laboratory equal numbers of the right and left-handed versions are made. ...
Perceptual distinction in an unsupervised neural network: implications for theories of category-specific deficits
(2000)
There are many reports of patients who, after sustaining brain damage, exhibit a selective recognition deficit for certain categories of object. There has been much controversy as to whether this is informative about the ...
