Antibiotics and resistance in farm animals
(1999)
Antibiotics are used in animals to cure disease and prevent suffering. Bacterial populations in animals which are exposed to these antibiotics may be selected for resistance. There is a concern that spread of these bacteria ...
Relevance theory and pragmatic impairment
(1999)
This paper summarizes aspects of relevance theory that are useful for exploring impairment of pragmatic comprehension in children. It explores data from three children with pragmatic language diffi culties within this ...
Monitoring the Ha Line in BL Lacertae - Evidence for an Accretion Disk
(Astronomical Society of the Pacific, 1999)
We present new spectroscopic observations of the recently discovered broad Ha line in BL Lacertae. These data, obtained over a period of 30 months, indicate that the line equivalent width is anti-correlated with the continuum ...
Stephen Heath : English critic, editor, and translator
(Fitzroy Dearborn, 1999)
The magnetic field structure of the DR21 region
(1999)
We present results of imaging polarimetry of the H2 v=1--0 S(1) line towards the outflow lobes of DR21. The polarization vectors are produced by dichroic absorption in a medium of aligned grains and therefore delineate the ...
Yield loss of winter oilseed rape in relation to severity of stem canker (Leptosphaeria maculans ) in the UK
(1999)
The relationships between yield loss and incidence or severity of stem canker in winter oilseed rape were analysed using data from experiments at Rothamsted in 1991/92, Withington in 1992/93, Boxworth in 1993/94 and ...
Ocular Galaxies: NGC 2535 and its Starburst Companion NGC 2536
(The International Astronomical Union, 1999)
Searching for the hidden broad-line region in Centaurus A
(1999)
We present the first near-infrared (K-band) spectropolarimetric observations of the nuclear region of Centaurus A. Although the data are of high signal-to-noise ratio, polarized broad Brγ is not detected and we place a 3σ ...
