S-pure Extensions of Locally Compact Abelian Groups
In this paper, we introduce the concept and study some properties of an
s-pure subgroup and a s-pure extension in the category of locally compact
abelian groups.Comment: 11 pages, accepted for publications in Hacettepe Journal of

The COBE Diffuse Infrared Background Experiment Search for the Cosmic Infrared Background: IV. Cosmological Implications
In this paper we examine the cosmological constraints of the recent DIRBE and
FIRAS detection of the extragalactic background light between 125-5000 microns
on the metal and star formation histories of the universe.Comment: 38 pages and 9 figures. Accepted for publications in The

A Review of AGB Mass Loss Imaging Techniques
Circumstellar imaging, across the electromagnetic spectrum, allows to derive
fundamental diagnostics for the physics of mass loss in the AGB phase. I review
the current status of the field, with particular emphasis on the techniques
that provide the strongest constraints for mass loss modeling efforts.Comment: accepted for publication in the Publications of the Astronomical

The Radio-FIR correlation: Is MHD Turbulence the Cause?
The radio - far infrared correlation is one of the tightest correlations
found in astronomy. Many of the models explaining this correlation rely on the
association of of global magnetic field strength with gas density. In this
letter we put forward that the physical reason for this association lies within
the processes of magnetohydrodynamic turbulence.Comment: Accepted by Publications of the Astronomical Society of Australi
A relaxation scheme for computation of the joint spectral radius of matrix sets
The problem of computation of the joint (generalized) spectral radius of
matrix sets has been discussed in a number of publications. In the paper an
iteration procedure is considered that allows to build numerically Barabanov
norms for the irreducible matrix sets and simultaneously to compute the joint
spectral radius of these sets.Comment: 16 pages, 2 figures, corrected typos, accepted for publication in

Representations of sport in the revolutionary socialist press in Britain, 1988–2012
This paper considers how sport presents a dualism to those on the far left of the political spectrum. A long-standing, passionate debate has existed on the contradictory role played by sport, polarised between those who reject it as a bourgeois capitalist plague and those who argue for its reclamation and reformation. A case study is offered of a political party that has consistently used revolutionary Marxism as the basis for its activity and how this party, the largest in Britain, addresses sport in its publications. The study draws on empirical data to illustrate this debate by reporting findings from three socialist publications. When sport did feature it was often in relation to high profile sporting events with a critical tone adopted and typically focused on issues of commodification, exploitation and alienation of athletes and supporters. However, readers’ letters, printed in the same publications, revealed how this interpretation was not universally accepted, thus illustrating the contradictory nature of sport for those on the far left
