Mid-infrared polarimetry and magnetic fields : an observing strategy
(2004)Linear polarimetry in the mid-infrared can be used to obtain magnetic field directions in astronomical sources. However, since the polarization can arise from emission and/or absorption from aligned grains, care is needed ... -
De-motivators Of Software Process Improvement : An Analysis Of Practitioners' Views
(2003)We present a study of software practitioners’ de-motivators for software process improvement (SPI). The aim of this study is to understand the nature of the issues that de-motivate software practitioners for SPI, so that ... -
Key success factors for implementing software process improvement : a maturity-based analysis
(2002)We report on a questionnaire survey of key success factors that impact software process improvement (SPI). We analysed responses to identify factors that have a major impact, or no impact, on implementing SPI. We found ... -
A quantitative and qualitative analysis of factors affecting software process improvement
(2003)Despite the growing body of research on software process improvement (SPI), there is still a great deal of variability in the success of SPI programmes. In this paper, we explore 26 factors that potentially affect SPI. We ... -
Privatisation of state-owned enterprises in Spain: redefining the political economy
(2001)Spain was at the forefront of a worldwide wave of privatisation in the 1990s. The process was driven by a mixture of pragmatism, belief in its economic benefits and a desire to be at the heart of Europe. It was lubricated ... -
Spanish foreign direct investment, transnationals and the redefinition of the Spanish business realm
(2001)Spanish outward direct investment grew substantially during the 1990s, transforming some Spanish businesses from national players to transnationals and adding a distinctive Latin American dimension to an essentially European ... -
The special operations executive in Norway 1940-1945: Policy and operations in the strategic and political context.
(De Montfort University, 2004)Between 1940 and 1945, the Special Operations Executive (SOE) carried out sabotage and organised resistance across occupied Europe. There have, however, only been a small number of scholarly studies of SOE’s activities, ... -
Association between congenital toxoplasmosis and preterm birth, low birth weight and small for gestational age birth
(2005)Objective To determine the association between congenital toxoplasmosis and preterm birth, low birthweight and small for gestational age birth. Design Multicentre prospective cohort study. Setting Ten European centres ... -
Promoting contraceptive services to teenagers
(2004)Following concerns regarding the rates of pregnancy and sexually transmitted infections (STIs) among teenagers in Britain, calls have been made to make sexual health services more accessible to young people. This paper ... -
OH maser mapping of the evolved star HD 179821: evidence for interacting outflows
(2001)The evolved star HD 179821 continues to be the subject of much debate as to whether it is a nearby post-asymptotic giant branch (post-AGB) star or a distant high initial mass post-red supergiant. We have mapped the OH maser ... -
Submillimetre photometry of post-asymptotic giant branch stars
(2002)Stars in the post-asymptotic giant branch (post-AGB) phase of evolution are surrounded by detached circumstellar envelopes containing dust which emits thermally in the mid- and far-infrared. Here we present 850-μm SCUBA ... -
MERLIN polarimetry of the OH masers in OH17.7-2.0
(2003)We report the first results of our study of magnetic fields in protoplanetary nebula candidates. Such fields may have important implications for the currently accepted Generalized Interacting Stellar Winds path to planetary ... -
Mid-infrared imaging of the dust shell around the post-asymptotic giant branch star HD 161796
(2003)We present mid-infrared (IR) images of HD 161796 (IRAS 17436+5003), taken with the OSCIR imager on the Gemini North Telescope, that resolve for the first time the thermal emission structure of the dust shell around this ... -
Functional Relaxation as Complementary Therapy in Irritable Bowel Syndrome : A Randomized, Controlled Clinical Trial
(2010)Objectives: Irritable bowel syndrome (IBS) is a frequently disabling and almost invariably distressing disease with a high overall prevalence. Numerous trials identified the importance of psychogenic and emotional etiological ... -
The disappearance of the 1667-MHz OH maser in IRAS 17436+5003 (HD 161796)
(2003)We report the diminution of the 1667-MHz OH maser in the post-asymptotic giant branch star IRAS 17436+5003, by a factor of ≳17 over a period of ≲12 yr, from observations with MERLIN. This circumstellar maser was detected ... -
MERLIN polarimetry of the OH masers in IRAS 20406+2953
(2004)We present the third in a series of results from our programme of the detection and measurement of magnetic fields in protoplanetary nebulae (PPN), using full-polarization MERLIN observations of OH masers. These are the ... -
A population model of the solar neighbourhood thin disc white dwarfs
(2004)We present a model of the solar neighbourhood (d < 100 pc) white dwarf (WD) population and show the resulting effective temperature and mass distribution. Our model parameters, in particular the WD cooling time-scale, are ... -
A study of two post-common envelope binary systems
(2005)We present intermediate-resolution, phase-resolved spectra of the close-binary systems EC 11575−1845 and V664 Cas, the central star of the planetary nebula HFG 1. Both systems have a very rich emission-line spectrum ... -
FUSE observations of PG1342+444 : new insights into the nature of the hottest DA white dwarfs
(2002)We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of the very hot (Teff≈60 000 K) DA white dwarf PG1342+444, describing our data reduction and analysis techniques. The spectrum reveals a number of ... -
Far-ultraviolet spectroscopy of the hot DA white dwarf WD 2218 706 (DeHt5) with STIS
(2001)We report a study of the photospheric composition of the hot DA white dwarf WD 2218+706, which is also the central star of the old planetary nebula DeHt5. Helium is detected in the far-UV spectrum. In addition, the star ...
