Centrality of hospitality and tourism education : the case of Strathclyde business school
Hospitality and tourism management education thrives at the University of Strathclyde. As Susan Hart, Kevin O’Gorman and Matthew Alexander explain, following the recent reorganisation, integrating the degree into the Strathclyde Business School has strengthened the university’s presentation of the subject’s distinctiveness. This is how future leaders of the industry will be developed
The Electrostatic Screening Length in Concentrated Electrolytes Increases with Concentration
According to classical electrolyte theories interactions in dilute (low ion
density) electrolytes decay exponentially with distance, with the Debye
screening length the characteristic length-scale. This decay length decreases
monotonically with increasing ion concentration, due to effective screening of
charges over short distances. Thus within the Debye model no long-range forces
are expected in concentrated electrolytes. Here we reveal, using experimental
detection of the interaction between two planar charged surfaces across a wide
range of electrolytes, that beyond the dilute (Debye-Huuckel) regime the
screening length increases with increasing concentration. The screening lengths
for all electrolytes studied - including aqueous NaCl solutions, ionic liquids
diluted with propylene carbonate, and pure ionic liquids - collapse onto a
single curve when scaled by the dielectric constant. This non-monotonic
variation of the screening length with concentration, and its generality across
ionic liquids and aqueous salt solutions, demonstrates an important
characteristic of concentrated electrolytes of substantial relevance from
biology to energy storage.Comment: This document is the unedited authors' version of a Submitted Work

ERAWATCH Country Report 2008 - An Assessment of Research System and Policies: Luxembourg
The main objective of ERAWATCH country reports 2008 is to characterise and assess the performance of national research systems and related policies in a structured manner that is comparable across countries. The reports are produced for each EU Member State to support the mutual learning process and the monitoring of Member States' efforts by DG Research in the context of the Lisbon Strategy and the European Research Area. In order to do so, the system analysis focuses on key processes relevant for system performance. Four policy-relevant domains of the research system are distinguished, namely resource mobilisation, knowledge demand, knowledge production and knowledge circulation. The reports are based on a synthesis of information from the ERAWATCH Research Inventory and other important available information sources.JRC.DG.J.3-Knowledge for Growt
Observational prospects for gravitational waves from hidden or dark chiral phase transitions
We study the gravitational wave (GW) signature of first-order chiral phase
transitions (PT) in strongly interacting hidden or dark sectors. We do so
using several effective models in order to reliably capture the relevant
non-perturbative dynamics. This approach allows us to explicitly calculate key
quantities characterizing the PT without having to resort to rough
estimates. Most importantly, we find that the transition's inverse duration
normalized to the Hubble parameter is at least two orders of
magnitude larger than typically assumed in comparable scenarios, namely
. The obtained GW spectra then suggest that
signals from hidden PTs occurring at around 100 MeV can be in reach of
LISA, while DECIGO and BBO may detect a stochastic GW background associated
with transitions between roughly 1 GeV and 10 TeV. Signatures of transitions at
higher temperatures are found to be outside the range of any currently proposed
experiment. Even though predictions from different effective models are
qualitatively similar, we find that they may vary considerably from a
quantitative point of view, which highlights the need for true first-principle
calculations such as lattice simulations.Comment: 35 pages, 9 figures. Extended discussion and updated calculation of

Herreshoff Marine Museum: Historical Analysis
These methods that Herreshoff utilized can be classified as early stages of the LEAN manufacturing concept which is used today in a majority of America’s leading manufacturers. Herreshoff made sure that his entire inventory was used and nothing was wasted. By reducing/eliminating waste, Nat preserved the value of his products and increased the efficiency of operation
Scaling analysis of the screening length in concentrated electrolytes
The interaction between charged objects in an electrolyte solution is a
fundamental question in soft matter physics. It is well-known that the
electrostatic contribution to the interaction energy decays exponentially with
object separation. Recent measurements reveal that, contrary to the
conventional wisdom given by classic Poisson-Boltzmann theory, the decay length
increases with ion concentration for concentrated electrolytes and can be an
order of magnitude larger than the ion diameter in ionic liquids. We derive a
simple scaling theory that explains this anomalous dependence of the decay
length on ion concentration. Our theory successfully collapses the decay
lengths of a wide class of salts onto a single curve. A novel prediction of our
theory is that the decay length increases linearly with the Bjerrum length,
which we experimentally verify by surface force measurements. Moreover, we
quantitatively relate the measured decay length to classic measurements of the
activity coefficient in concentrated electrolytes, thus showing that the
measured decay length is indeed a bulk property of the concentrated electrolyte
as well as contributing a mechanistic insight into empirical activity
coefficients.Comment: To appear in Physical Review Letter
ERAWATCH COUNTRY REPORTS 2011: Luxembourg
The main objective of the ERAWATCH Annual Country Reports is to characterise and assess the performance of national research systems and related policies in a structured manner that is comparable across countries.
The 2011 country reports assess the evolution on the national R&D investments targets, the efficiency and effectiveness of national policies and investments into R&D, the articulation between education, research and innovation, with an increased focus on the last two in terms of their wider governance and policy mix. The reports for EU MS and AS integrates in the assessment the evolution of the national policy mixes in the perspective of the Europe 2020 Strategy goals and on the realisation and better governance of ERA.JRC.J.2-Knowledge for Growt
Draft Genome Sequences of Four NDM-1-Producing Klebsiella pneumoniae Strains from a Health Care Facility in Northern California.
We report the draft genome sequences of Klebsiella pneumoniae strains from four patients at a northern California health care facility. All strains contained the New Delhi metallo-β-lactamase (NDM1) carbapenemase with extended antibiotic resistance, including resistance to expanded-spectrum cephalosporins, imipenem, ertapenem, and meropenem. NDM gene alignments revealed that the resistance was plasmid encoded
