An 80-kpc Ly alpha halo around a high-redshift type-2 quasi-stellar object
(2009)
We announce the discovery of an extended emission line region associated with a high redshift type-2 QSO. The halo, which was discovered in our new wide-field narrow-band survey, resides at z = 2.85 in the Spitzer First ...
Radio Galaxy Physics at Low Frequencies: Lobes, Jets and Environments
(Astronomical Society of the Pacific, 2009)
I discuss the key role of low-frequency observations in determining the physical properties of radio galaxies and radio-loud quasars, and their application in studies of the interaction between radio sources and their ...
The 6-GHz multibeam maser survey – I. Techniques
(2009)
A new 7-beam 6−7 GHz receiver has been built to survey the Galaxy and the Magellanic Clouds for newly forming high-mass stars that are pinpointed by strong methanol maser emission at 6668 MHz. The receiver was jointly ...
Central stars of planetary nebulae in SDSS and IPHAS
(2009)
Space densities and birthrates of Planetary Nebulae (PNe) are highly uncertain. A large range of formation rates has been derived by different studies, which has led to contradicting ideas for the final evolutionary phases ...
Early music education as a tool for inclusion and respect for diversity : study paper for the Bernard van Leer Foundation.
(University of Brighton and Bernard van Leer Foundation, 2009)
This paper explores the topic of using music education activities as a way to address inclusion and respect for diversity with children. It is intended to inform the development of appropriate activities and indicators for ...
Automatic calculation of coverage profiles for coverage-based testings
(2009)
Code-coverage-based testing is a widely-used testing strategy with the aim of providing a meaningful decision criterion for the adequacy of a test suite. Code-coverage-based testing is also used for the development of ...
Effect of listening to Nellie the Elephant during CPR training on performance of chest compressions by lay people : randomised crossover trial
(2009)
To determine whether listening to music during cardiopulmonary resuscitation (CPR) training increases the proportion of lay people delivering chest compressions of 100 per minute.
SFG realization of wavelet filter using switched-current circuits
(2009)
A signal flow graph method for analogue implementation of wavelet transform using switched-current circuits is proposed in which the wavelet transform is synthesized by a bank of switched-current bandpass filters whose ...
Calcium- and myosin-dependent changes in troponin structure during activation of heart muscle
(2009)
Each heartbeat is triggered by a pulse of intracellular calcium ions which bind to troponin on the actin-containing thin filaments of heart muscle cells, initiating a change in filament structure that allows myosin to bind ...
