Effective charge of the (pi)h(11/2) orbital and the electric field gradient of Hg from the Yrast structure of 206Hg.

The gamma-ray decay of excited states of the two-proton hole nucleus, 206Hg, has been identified using Gammasphere and 208Pb+238U collisions. The yrast states found include a T(1/2) = 92(8) ns 10(+) isomer located above the known 5(-) isomer. The B(E2;10(+)-->8(+)) strength is used to derive the quadrupole polarization charge induced by the h(11/2) proton hole. Also, the implied quadrupole moment has been used to provide an absolute scale for the electric field gradient of Hg in Hg metal.

Magic nucleus 132Sn and its one-neutron-hole neighbor 131Sn.

Prompt and delayed gamma-ray cascades in doubly magic 132Sn and its neighbor 131Sn have been studied at Gammasphere using a 248Cm fission source. Isotopic assignments of unknown gamma rays were based on coincidences with known transitions in A = 112-116 Pd fission partners. The yrast level spectra of both tin nuclei are interpreted using empirical nucleon-nucleon interactions from the 132Sn and 208Pb regions. Results include identification of the (nuf(7/2)h(-1)(11/2))9(+) aligned state in 132Sn and of extensive (nuf(7/2)h(-2)(11/2)), (nuf(7/2)d(-1)(3/2)h(-1)(11/2)) and (nuh(-1)(11/2)x3(-)) multiplets in 131Sn. The previously reported beta(-) decay of an unusual 131In high-spin isomer to levels in 131Sn is also elucidated.

Treated and untreated recovery from alcohol misuse: environmental influences and perceived reasons for change.

This Swedish study compared assisted and unassisted subjects with different long-term drinking outcomes with regard to drinking patterns, significant life events, and attributions as to what initiated and maintained recovery. It was found that both recovery, independent of help-seeking status, and help-seeking, independent of long-term outcome, were preceded by prolonged harmful drinking consequences and increasing negative stress. Initial attempts to solve the drinking problem were followed by a significant reduction in life stress, but stable recovery was uniquely associated with stability and/or major improvements in the life context. Unassisted recovery was more often gradual in character and/ or motivated by positive incentives than assisted recovery. Possible clinical and social-political implications are discussed.

Frequency of patients with acute asthma in relation to ozone, nitrogen dioxide, other pollutants of ambient air and meteorological observations.

OBJECTIVE: To study the association of the daily frequency of registration of patients with acute asthma at the emergency department of a central hospital in the south-west of Sweden with levels of air pollution and meteorological observations. METHODS: A retrospective longitudinal study was made of asthma patients taken from a hospital registry. This information was correlated with measurements of ozone, nitrogen dioxide, sulphur dioxide, toluene, temperature and relative humidity. Patients were from the catchment area of the Central Hospital of Halmstad containing around 120,000 inhabitants. A total of 4127 visits of patients with acute asthma to the emergency department at the Central Hospital of Halmstad were registered during a period of 1247 days from January 1990 to May 1993. The differential optical absorption spectroscopy (DOAS) technique was used to monitor levels of air pollutants over a distance of 1000 m in the central part of the town of Halmstad. Data on temperature, relative humidity, precipitation, wind speed and wind direction for the time period were supplied by the Swedish Meteorological and Hydrological Institute (SMHI). RESULTS: There were many statistically significant correlations between the levels of air pollutants and the meteorological measurements and a strong negative correlation between ozone and nitrogen dioxide. There was a statistically significant effect on asthma visits in children of low temperature and high nitrogen dioxide levels, and on asthma visits in adults of high temperature and high levels of ozone. CONCLUSIONS: There was a different reaction pattern in children and adults with asthma regarding temperature and ozone/nitrogen dioxide. The strong correlations between temperature and air pollution and between the levels of ozone and nitrogen dioxide made the true relation between asthma, air pollution and temperature hard to evaluate statistically.

Paths to recovery from substance misuse: change of lifestyle and the role of treatment.

Controlled outcome studies have, on the whole, failed to demonstrate more than rather weak and short-lived effects of substance misuser treatment. There is, at the same time, growing evidence that people often recover from substance misuse problems without the help of formal treatment. This state of affairs has, not least in times of economic recession, been taken as an argument for cutting fundings of treatment facilities and other forms of formal help. This article questions that present knowledge necessarily justifies such conclusions. We do know that even severe misusers are sometimes capable of changing their way of life. We do not, however, know very much about the circumstances and situations-planned or not and designated as "treatment" or something else-that contribute to such change processes. A closer integration of two research areas-outcome research and research on "spontaneous recovery"-is proposed as a way of learning more about the possible interplay between "real life" events, various formal interventions, and change of life style.
