Raving about Ravens : modelling speed-accuracy in intelligence tests
(International Society for Psychophysics, 2005-10)
The effect of time pressure on performance on intelligence tests is a long standing problem. In this study a computerised version of the Ravens Advanced Progressive Matrices was administered using 3 different forms of ...
Methods for studying population structure, including sensitivity to the fungicide silthiofam, of the cereal take-all fungus, Gaeumannomyces graminis var. tritici
(2005-10)
Field isolates (n = 144) of the wheat take-all fungus Gaeumannomyces graminis var. tritici (Ggt) were tested for sensitivity to silthiofam, a take-all-specific fungicide used as a seed treatment, and identified as A- or ...
Structural analysis of divalent metals binding to the Bacillus subtilis response regulator Spo0F : the possibility for In vitro metalloregulation in the initiation of sporulation
(2005-10)
The presence of a divalent metal ion in a negatively charged aspartic acid pocket is essential for phosphorylation of response regulator proteins. Here, we present metal binding studies of the Bacillus subtilis response ...
Towards a parity-dependent level density for astrophysics
(2005-10)
Astrophysical reaction rates are sensitive to the parity distribution at low excitation energies. We combine a formula for the energy-dependent parity distribution with a microscopic-macroscopic nuclear level density. This ...
Micro throttle pump employing displacement amplification in an elastomeric substrate
(2005-10)
We report a micro throttle pump (MTP) with enhanced throttling resulting from beneficial deformation of its elastomer substrate. In the MTP reported, this has doubled the effective deflection of the piezo electric (PZT) ...
Continuously variable mixing-ratio micromixer with elastomer valves
(2005-10)
We report a self-contained microfluidic alternate flow injection mixer (AFIM) employing piezoelectrically actuated, PDMS seal-valves to control injection. AFIMs employ pulsatile injection of liquids to enhance interface ...
Great Expectations : Sixth-formers' perceptions of teaching and learning in degree-level English
(2005-10)
This article feeds into the discussion of transitional issues begun in Volume 2 of Arts and Humanities in Higher Education. It draws on research into A-level students' expectations of university English and how these compare ...
High-pressure aerosol suspensions : A novel laser diffraction particle sizing system for hydrofluoroalkane pressurised metered dose inhalers
(2005-09-30)
In this study, a novel laser diffraction particle size analysis dispersion system, capable of sizing particles in situ within suspension hydrofluoroalkane (HFA) pressurised metered dose inhalers (pMDIs), was developed and ...
