Methods of quantum field theory for trapped Bose–Einstein condensates
(2004)In this tutorial we present an introduction to some theoretical methods of quantum field theory applied to the description of a trapped Bose–Einstein condensate. First of all, we give a brief account of the main characteristics ... -
Isolation and characterisation of the mating-type (MAT) locus from Rhynchosporium secalis
(2003-12-31)The mating-type (MAT) genes from Rhynchosporium secalis were isolated using PCR-based methods. Characterisation of the MAT idiomorphs suggests that R. secalis is closely related to the discomycetes Pyrenopeziza brassicae ... -
Elastomer-glass micropump employing active throttles
(2004)We report a reciprocating microfluidic pump, the Micro Throttle Pump (MTP), constructed in a relatively uncomplicated manner from glass and microstructured poly(dimethylsiloxane) (PDMS). Unconventionally, the MTP employs ... -
The Creation of Transformative Learning Cultures in Higher Education
(University of Hertfordshire, 2013-05-08)This research claims that transformative as opposed to informative learning cultures in higher education are capable of promoting student identity development alongside subject development. It makes a significant pedagogical, ... -
The molecular mystery of neuronal migration : FAK and Cdk5
(2004)The basic building blocks of a cell are its cytoskeletal proteins, the orderly but dynamic organization of which is essential. How signalling molecules regulate the cytoskeleton in the developing nervous system is still ... -
Inhibitors of multidrug resistance (MDR) have affinity for MDR substrates
(2004-02-23)Multidrug-resistance (MDR) occurs in many bacterial species and tumour cells. MDR functions by membrane proteins which export drugs from cells, resulting in a low ineffective concentration of the drug. We have shown by ... -
Comparative epidemiology of Pyrenopeziza brassicae (light leaf spot) ascospores and conidia from Polish and UK populations
(2004-02)Despite differences in climate and in timing of light leaf spot epidemics between Poland and the UK, experiments provided no evidence that there are epidemiological differences between populations of Pyrenopeziza brassicae ... -
An investigation of calibration methods for solution calorimetry
(2004-01-28)Solution calorimetry has been used in a number of varying applications within pharmaceutical research as a technique for the physical characterisation of pharmaceutical materials, such as quantifying small degrees of ... -
X-Ray Studies of Radio-Loud AGN
(University of Hertfordshire, 2013-05-24)In this thesis I use X-ray observations to study the cores and extended structures of radio-loud AGN, to determine their structure, accretion properties and the impact they have on their surroundings. I use new Chandra ... -
An Assets Based Approach to Health Promotion with Young People in England
(University of Hertfordshire, 2013-05-21)Introduction The health of young people in England is an area of concern, nationally and internationally. This has prompted a range of strategies and policies to try to address how health may be improved. However, there ... -
Women's Views on Partnership Working with Midwives During Pregnancy and Childbirth
(University of Hertfordshire, 2013-05-22)United Kingdom (UK) health policy over the past thirty years has been predicated on a partnership model focusing on empowering service users to be fully involved in their care. Within maternity care partnership relationships ... -
An investigation into alleged 'hauntings'
(2003-05)In cases of alleged hauntings, a large number of seemingly trustworthy witnesses consistently report experiencing unusual phenomena (e.g. apparitions, sudden changes in temperature, a strong sense of presence) in certain ... -
Auditory navigation in hyperspace : Design and evaluation of a non-visual hypermedia system for blind users
(1999)This paper presents the design and evaluation of a hypermedia system for blind users, making use of a non-visual interface, non-speech sounds, three input devices, and a 37 node hypermedia module. The important components ... -
Molecular variation of Potato yellow vein virus isolates
(2004-04-01)To evaluate the variation of Potato yellow vein virus from potato fields, 12 isolates were collected from Colombia and one was collected from Peru. Double-stranded RNA was extracted from the plants and used as a template ... -
The transmembrane CXC-chemokine ligand 16 is induced by IFN-gamma and TNF-alpha and shed by the activity of the disintegrin-like metalloproteinase ADAM10
(2004-05-15)The novel CXC-chemokine ligand 16 (CXCL16) functions as transmembrane adhesion molecule on the surface of APCs and as a soluble chemoattractant for activated T cells. In this study, we elucidate the mechanism responsible ... -
Engineering of computer-based systems : A proposed curriculum for a degree program at bachelor level
(2004-05)This paper presents a curriculum proposal for an Engineering of Computer-Based Systems (ECBS) Bachelor program from the Working Group on Education and Training of the IEEE Computer Society ECBS Technical Committee. It ... -
Determination of polyvinylpyrrolidone using high-performance liquid chromatography
(2004-05-28)Polyvinylpyrrolidone (PVP) is a versatile polymer with innate surface activity. It is very difficult to accurately assay due to its wide molecular weight range and amphiphilic nature. This study evaluated a reversed-phase ... -
The effects of progressive root removal prior to planting on shoot and root growth of Betula pendula Roth
(2004-07-01)Root loss during transplanting of bare rooted nursery stock is thought to limit water uptake during establishment. An initial investigation into the effects on growth under well watered conditions of progressive removal ... -
Investigation of the stabilisation of freeze-dried lysozyme and the physical properties of the formulations
(2004-07)The long-term stability of a protein formulation requires that the glass transition temperature (T-g) of the formulation should be maximised and the perturbation of the protein native structure in the dried form after ... -
Analysis of the RNA of Potato yellow vein virus : Evidence for a tripartite genome and conserved 3′-terminal structures among members of the genus Crinivirus
(2004-07-01)Double-stranded RNA preparations produced from potato plants graft-inoculated with a Peruvian isolate of Potato yellow vein virus (PYVV; genus Crinivirus, family Closteroviridae) contain five RNA species denoted RNA 1, RNA ...
