Working with graphic design students to promote `Land of Lost ContentÂż at Leeds Met.
yesAs Leeds Metropolitan is a university of festivals
and partnerships, the library was given the opportunity
this year to host a festival to promote the
library and all its services to the university. The
library festival was a week of events and activities
to promote the library and its space in new ways.
It was a good way to remind staff and students of
the value of libraries, not only as places to learn
but also as places to enhance our leisure and
working lives ... we chose to promote the database `Land of Lost
ContentÂż. This was because graphic design and
art students are based at our campus and we also
thought this database would attract a wide range
of students who might otherwise think that electronic
databases contain little of interest for them.
Our promotion has been so successful in many
ways that we would like to share our experience
with other librarians
Properties of the moon and its environment from lunar magnetometer measurements
Lunar analysis of data from a total of nine lunar magnetometers is described. Results obtained concerning electromagnetic, compositional, and structural properties of the lunar interior are discussed. Specific topics covered include: lunar magnetic permeability and iron abundance; limits on a highly conducting lunar core; lunar electrical conductivity; and internal structure inferred from conductivity and permeability results

Fire and rescue service reconfiguration: a case study in Nottinghamshire
The Fire Cover Review in Nottinghamshire arises out of the Integrated Risk Management Planning process introduced in the UK by the Fire and Rescue 2004 Act,. It is intended to provide the evidence and analysis for the reconfiguration of services and the future deployment of resources in in the short, medium and long terms. Any future reconfigurations of services must be based on contemporary and comprehensive risk assessments of the areas affected.(ODPM 2004). The need to undertake the review pre-dated the current financial crises, the general election and the need for significant reductions in public expenditure in the UK, although these circumstances made the review more challenging and politically sensitive. This paper evaluates the practical implementation of the Integrated Risk Management Planning process and the Fire Cover Review in Nottinghamshire to identify good practice and to generate recommendations for improving the process and its implementation
Feasibility and Performance of the Microwave Thermal Rocket Launcher
Beamed-energy launch concepts employing a microwave thermal thruster are feasible in principle, and microwave sources of sufficient power to launch tons into LEO already exist. Microwave thermal thrusters operate on an analogous principle to nuclear thermal thrusters, which have experimentally demonstrated specific impulses exceeding 850 seconds. Assuming such performance, simple application of the rocket equation suggests that payload fractions of 10% are possible for a single stage to orbit (SSTO) microwave thermal rocket. We present an SSTO concept employing a scaled X-33 aeroshell. The flat aeroshell underside is covered by a thin-layer microwave absorbent heat-exchanger that forms part of the thruster. During ascent, the heat-exchanger faces the microwave beam. A simple ascent trajectory analysis incorporating X-33 aerodynamic data predicts a 10% payload fraction for a 1 ton craft of this type. In contrast, the Saturn V had 3 non-reusable stages and achieved a payload fraction of 4%
Seeing but not perceiving: Inattentional blindness as a cause of missed cues in the general practice (GP) consultation
Background
It is well known that healthcare professionals, including GPs, frequently fail to respond to cues made by their patients. A possible explanation for this behaviour is that the phenomenon of IB could lead to a failure to observe the cue, rather than a deliberate choice to ignore it. This study sought to explore that possibility, and to consider whether GP trainees are more susceptible to IB than GP trainers.
Aim
A pre-recorded video of a simulated consultation was used, where the patient gave two significant cues which were not picked up by the doctor in the video. The aim was to compare the rates with which both trainee GPs and GP trainers observed these missed cues.
Methods
The research was a case study involving two groups of participants - GP trainees and GP trainers from a localised GP Training Scheme. Actors were used to record a video of a pre-defined GP consultation involving a patient affected by headaches, who gave two significant cues which were not responded to in the video. Participants observed the video while being asked to focus on the diagnosis and management of the patient’s headaches, following which they completed a questionnaire, including questions about the cues.
Results
Cues were missed by 24-53% of participants, suggesting a high rate of IB within the GP consultation. Unexpected findings included the recording by some participants of false observations from the video. There was no significant difference between trainers and trainees in the rates of IB.
Conclusions
IB appears to be a real and significant phenomenon within the GP consultation, and is likely to have important implications for patient care. More research is needed to confirm these findings, establish IB rates as a cause of missed cues among healthcare professionals and evaluate possible interventions to reduce susceptibility to IB
Transport and Magnetic Properties of FexVse2 (x = 0 - 0.33)
We present our results of the effect of Fe intercalation on the structural,
transport and magnetic properties of 1T-VSe2. Intercalation of iron, suppresses
the 110K charge density wave (CDW) transition of the 1T-VSe2. For the higher
concentration of iron, formation of a new kind of first order transition at
160K takes place, which go on stronger for the 33% Fe intercalation.
Thermopower of the FexVSe2 compounds (x = 0 - 0.33), however do not show any
anomaly around the transition. The intercalation of Fe does not trigger any
magnetism in the weak paramagnetic 1T-VSe2, and Fe is the low spin state of
Fe3+.Comment: 7 pages, 8 figures, 2 table
Tunneling Anisotropic Magnetoresistance of Helimagnet Tunnel Junctions
We theoretically investigate the angular and spin dependent transport in
normal-metal/helical-multiferroic/ferromagnetic heterojunctions. We find a
tunneling anisotropic magnetoresistance (TAMR) effect due to the spiral
magnetic order in the tunnel junction and to an effective spin-orbit coupling
induced by the topology of the localized magnetic moments in the multiferroic
spacer.
The predicted TAMR effect is efficiently controllable by an external electric
field due to the magnetoelectric coupling
Iron abundance and magnetic permeability of the moon
A larger set of simultaneous data from the Apollo 12 lunar surface magnetometer and the Explorer 35 Ames magnetometer are used to construct a whole-moon hysteresis curve, from which a new value of global lunar permeability is determined to be mu = 1.012 + or - 0.006. The corresponding global induced dipole moment is 2.1 x 10 to the 18th power gauss-cu cm for typical inducing fields of .0001 gauss in the lunar environment. From the permeability measurement, lunar free iron abundance is determined to be 2.5 + or - 2.0 wt. %. Total iron abundance (sum of iron in the ferromagnetic and paramagnetic states) is calculated for two assumed compositional models of the lunar interior: a free iron/orthopyroxene lunar composition and a free iron/olivine composition. The overall lunar total iron abundance is determined to be 9.0 + or - 4.7 wt. %. Other lunar models with a small iron core and with a shallow iron-rich layer are discussed in light of the measured global permeability
