New H1 results on isolated leptons and missing pt at HERA
The search for events containing isolated leptons (electrons or muons) and
missing transverse momentum produced in collisions is performed with
the H1 detector at HERA in the period 1994--2005. The analysed data sample
corresponds to an integrated luminosity of 279 pb, which includes 53
pb of data and 107 pb of data from the new
HERA~II phase. A total of 40 events are observed in the data, compared to a
Standard Model (SM) prediction of 34.3 4.8. At large hadronic transverse
momentum 25 GeV, a total of 17 events are observed compared to
9.0 1.5 predicted by the SM. In this region, 15 events are observed in
the data compared to a SM prediction of 4.6 0.8, whereas in the
data 2 events are observed compared to a SM prediction of 4.4

The Role of Community Centre-based Arts, Leisure and Social Activities in Promoting Adult Well-being and Healthy Lifestyles
Developed countries are experiencing high levels of mental and physical illness associated with long term health conditions, unhealthy lifestyles and an ageing population. Given the limited capacity of the formal health care sector to address these public health issues, attention is turning to the role of agencies active in civil society. This paper sought to evaluate the associations between participation in community centre activities, the psycho-social wellbeing and health related behaviours. This was based on an evaluation of the South West Well-being programme involving ten organisations delivering leisure, exercise, cooking, befriending, arts and crafts activities. The evaluation consisted of a before-and-after study with 687 adults. The results showed positive changes in self-reported general health, mental health, personal and social well-being. Positive changes were associated with diet and physical activity. Some activities were different in their outcomes—especially in cases where group activities were combined with one-to-one support. The results suggest that community centre activities of this nature offer benefits that are generically supportive of health behaviour changes. Such initiatives can perform an important role in supporting the health improvement objectives of formal health care services. For commissioners and partner agencies, accessibility and participation are attractive features that are particularly pertinent to the current public health context
Rotational friction on small globular proteins: Combined dielectric and hydrodynamic effect
Rotational friction on proteins and macromolecules is known to derive
contributions from at least two distinct sources -- hydrodynamic (due to
viscosity) and dielectric friction (due to polar interactions). In the existing
theoretical approaches, the effect of the latter is taken into account in an
{\it ad hoc} manner, by increasing the size of the protein with the addition of
a hydration layer. Here we calculate the rotational dielectric friction on a
protein () by using a generalized arbitrary charge distribution
model (where the charges are obtained from quantum chemical calculation) and
the hydrodynamic friction with stick boundary condition,
() by using the sophisticated theoretical technique known
as tri-axial ellipsoidal method, formulated by Harding [S. E. Harding, Comp.
Biol. Med. {\bf 12}, 75 (1982)]. The calculation of hydrodynamic friction is
done with only the dry volume of the protein (no hydration layer). We find that
the total friction obtained by summing up and
gives reasonable agreement with the experimental results,

Designing and implementing a communications strategy: lessons learnt from HIV and Sexual and Reproductive Health Research Programme Consortia.
In recent years there has been increasing recognition of the importance of strategic research communication. Health research organisations need to be able to communicate their research effectively to increase the probability that the findings influence policy and practice, and benefit those in greatest need. Many research funders are making communications a requirement of research funding. This paper reflects on the experience in developing and implementing communications strategies of several Research Programme Consortia funded by the Department for International Development.Different research topics will require different communications approaches in order to be effective. This is reflected in the diversity of strategies employed by different research programmes. Strategic research communications designed to influence policy and practice require different skills and expertise from those required for carrying out research and writing it up for publication in academic journals. Therefore researchers involved in communicating research should be supported in this work. One of the ways in which research programme consortia have sought to do this is through convening workshops to develop the communications skills of researchers from partner organisations. These have proven invaluable. Another way of providing ongoing support to those involved in communicating research is through a Communications Community of Practice. Where this has been used it has proven a good way to support researchers both with ideas and resources, but also a strong sense of belonging to a community that shares a common concern with communication. Developing strong partnerships with research users, other research organisations, knowledge intermediaries and other stakeholders is vital for effective communication.Embracing the challenges and opportunities presented by communicating research to influence policy practice is vital if research is to have maximum possible impact, and demonstrate its worth at a time when funding for health and development activities is at risk. Sharing lessons learnt in this process between research programmes is important to support this work
Functional equivalence of grasping cerci and nuptial food gifts in promoting ejaculate transfer in katydids.
The function of nuptial gifts has generated longstanding debate. Nuptial gifts consumed during ejaculate transfer may allow males to transfer more ejaculate than is optimal for females. However, gifts may simultaneously represent male investment in offspring. Evolutionary loss of nuptial gifts can help elucidate pressures driving their evolution. In most katydids (Orthoptera: Tettigoniidae), males transfer a spermatophore comprising two parts: the ejaculate-containing ampulla and the spermatophylax-a gelatinous gift that females eat during ejaculate transfer. Many species, however, have reduced or no spermatophylaces and many have prolonged copulation. Across 44 katydid species, we tested whether spermatophylaces and prolonged copulation following spermatophore transfer are alternative adaptations to protect the ejaculate. We also tested whether prolonged copulation was associated with (i) male cercal adaptations, helping prevent female disengagement, and (ii) female resistance behavior. As predicted, prolonged copulation following (but not before) spermatophore transfer was associated with reduced nuptial gifts, differences in the functional morphology of male cerci, and behavioral resistance by females during copulation. Furthermore, longer copulation following spermatophore transfer was associated with larger ejaculates, across species with reduced nuptial gifts. Our results demonstrate that nuptial gifts and the use of grasping cerci to prolong ejaculate transfer are functionally equivalent
