Scattering of particles produced in high energy nuclear collisions can wrestle the system into a state near local thermal equilibrium. I illustrate how measurements of the centrality dependence of the mean transverse momentum and its fluctuations can exhibit this thermalization.
BACKGROUND: Policies and practice in many sectors affect health. Health impact assessment (HIA) is a way to predict these health impacts, in order to recommend improvements in policies to improve health. There has been debate about appropriate methods for this work. The Scottish Executive funded the Scottish Needs Assessment Programme to conduct two pilot HIAs and from these to develop guidance on HIA. METHODS: Case study 1 compared three possible future scenarios for developing transport in Edinburgh, based on funding levels. It used a literature review, analysis of local data and the knowledge and opinions of key informants. Impacts borne by different population groups.were compared using grids. Case study 2 assessed the health impacts of housing investment in a disadvantaged part of Edinburgh, using published literature, focus groups with community groups and interviews with professionals. RESULTS: Disadvantaged communities bore more detrimental effects from the low transport investment scenario, in the areas of: accidents; pollution; access to amenities, jobs and social contacts; physical activity; and impacts on community networks. The housing investment had greatest impact on residents' mental health, by reducing overcrowding, noise pollution, stigma and fear of crime. CONCLUSION: Although there is no single 'blueprint' for HIA that will be appropriate for all circumstances, key principles to inform future HIA were defined. HIA should be systematic; involve decision-makers and affected communities; take into account local factors; use evidence and methods appropriate to the impacts identified and the importance and scope of the policy; and make practical recommendations.
OBJECTIVE: Health Impact Assessment (HIA) provides a method of predicting the health impacts of policies and activities, in order to recommend changes that would improve health. We piloted approaches to health impact assessment and made recommendations for its use as part of the planning and policy making processes in Scotland. DESIGN: Two Health Impact Assessments were done as case studies. One assessed the City of Edinburgh Council's Local Transport Strategy. The other assessed North Edinburgh Area Renewal Housing Strategy. Both were done in partnership with the professionals responsible for developing the strategies. RESULTS: The main health impacts of transport strategy were in the areas of: accidents, pollution, access to amenities, jobs and social contacts, opportunities for physical activity in walking and cycling and impacts on community networks. Overall, housing strategy impacted most on mental health, especially stress and depression. The recommendations of both HIAs are being used in developing the strategies further. CONCLUSIONS: Health impact assessment can make explicit the health consequences of decisions in different sectors, including impacts on health inequalities. Health Impact Assessment should be done as part of community planning and other partnership activities. Consideration of health impacts should become part of routine decision making.

A sensitive ELISA was developed to monitor the persistence of a specific antibody, rabbit anti-BSA, in the bloodmeal, haemolymph and tissues of the mosquito Anopheles stephensi Liston. Different concentrations of anti-BSA were fed to female mosquitoes in sheep blood, via a membrane-feeder, and it was found that antibody persisted in the gut as the bloodmeal was digested: concentrations present at 24 h were directly related to those fed. Homogenates of mosquito bodies, from which the intact guts had been removed, were always antibody-positive up to 9 days post-feeding, indicating that undigested antibody had passed through the gut wall into the haemocoele. Haemolymph was extracted from mosquitoes at different times post-feeding, using a microcapillary and manipulator, and antibody was detected in several of the assays. The level of antibodies in the haemolymph 24 h post-feeding was less than half of the level in mosquito heads, indicating removal of antibodies from the haemolymph, perhaps by binding onto haemocoelic tissues. The relevance of these results to the ingestion, survival and fate of antibody against malaria sporozoites is discussed.
