Decoding the spectra of SDSS early-type galaxies : New indicators of age and recent star formation
(2007-12-01)
We apply principal component analysis (PCA) to a sample of early-type galaxies from the Sloan Digital Sky Survey (SDSS) in order to infer differences in their star formation histories from their unresolved stellar populations. ...
The effect of environment on the ultraviolet color-magnitude relation of early-type galaxies
(2007-12-01)
We use GALEX near-UV (NUV ) photometry of a sample of early-type galaxies selected in the SDSS (Sloan Digital Sky Survey) to study the UV color-magnitude relation (CMR). NUV - r color is an excellent tracer of even small ...
Motivating developer performance to improve project outcomes in a high maturity organization
(2007-12)
In this paper we discuss the impact software developer performance has on project outcomes. Project performance remains unreliable in the software industry with many compromised software systems reported in the press. We ...
A modified procedure for isolating double-stranded RNA: Application to diagnosis of Amasya cherry disease
(2007-12)
A novel method of isolating double-stranded RNA (dsRNA) from cherry leaves affected with Amasya cherry disease (ACD) using silica capture in combination with non-ionic cellulose was developed. Unfractionated RNAs prepared ...
Nail swelling as a pre-formulation screen for the selection and optimisation of ungual penetration enhancers
(2007-12)
Introduction. Targeting drug treatment to fungal infections that reside within or below the nail plate is problematic due to the highly restrictive barrier of the human nail. To optimise topical formulations for ungual ...
The look-back time evolution of far-ultraviolet flux from the brightest cluster elliptical galaxies at z <0.2
(2007-12-01)
We present the GALEXUV photometry of the elliptical galaxies in Abell clusters at moderate redshifts (z <0.2) for the study of the look-back time evolution of the UV upturn phenomenon. The brightest elliptical galaxies (M ...
Homeostatic role of toll-like receptor 4 in the endothelium and heart
(2007-12)
Toll-like receptor 4 (TLR4) is a pattern recognition receptor for lipopolysaccharide from Gram negative bacteria and thus is integral to the innate immune response in mammals. In addition, TLR4 is associated with atherosclerosis ...
UV-optical colors as probes of early-type galaxy evolution
(2007-12-01)
We have studied ∼2100 early-type galaxies in the SDSS DR3 which have been detected by the GALEX Medium Imaging Survey (MIS), in the redshift range O <z <0.1.1. Combining GALEXUV photometry with corollary optical data from ...
Calculated densities of H3O+(H2O)n,NO2− (H2O)n, CO3− (H2O)n and electron in the nighttime ionosphere of Mars : Impact of solar wind electron and galactic cosmic rays
(2007-12-01)
We have calculated the densities of positive ions and negative ions in the ionosphere of Mars at solar zenith angle 106° between height interval 0 km and 220 km. This model couples ion-neutral, electron neutral, dissociation ...
Osteoporosis : A teenage perspective
(2007-12)
Objectives: To assess the knowledge and health beliefs, on osteoporosis, of 16-18 year olds in full-time education in the UK. This is believed to be an age where peak bone mass, a significant factor in osteoporosis and ...
