(Z. Naturforsch. 31a , 1 3 0 [1976 ] ; received November 14, 1975) During collisions of heavy ions with heavy targets below the Coulomb barrier, adiabatic molecular orbitals are formed for the inner electrons. Deviations from adiabaticity lead to coupling between various states and can be treated by time-dependent perturbation theory. For high charges ( Z 1 + Z 2 60) the molecular electrons are...

BACKGROUND AND PURPOSE Temporal trends in stroke incidence in Denmark have not been previously reported. The Copenhagen City Heart Study is a prospective study based on a randomly selected sample of an urban population of, initially, 19,698 participants followed since 1976. Over a period of 12 years, we studied three important aspects of stroke incidence in 848 identified cases: temporal trends...

In 1976, for the second fiscal year in a row, public expenditures for social welfare purposes expanded at an abnormally high rate. Even after adjusting the 16-percent increase in aggregate expenditures for price and population changes, the 8-percent real growth rate proves to be the highest since 1971. The $45 billion rise in social welfare expenditures to a total of $331 billion reflects the e...

The work is well organised into three sections covering the first century, the period of scientific advance 1876-1946 and the period of explosive growth 1946-1976. In the first section there is a selective account of medical education and practice and of hygiene and hospitals and of the conflicts and stresses in a country where varied standards prevailed. In the period of scientific advance the...

A tobacco-like odorous compound isolated from a bloom of the blue-green alga M icrocystis w esenbergii and a laboratory culture of M. aeruginosa was analysed by gas-liquid chromatography and mass spectrometry. Its structure was determined as /?-cyclocitral. No other monoterpenes have been detected in these and in other blue-green algae. The hydrocarbon content was 0.10 — 0.18% of the dry weight...

Between 1 September and 24 October 1976, 318 cases of acute viral haemorrhagic fever occurred in northern Zaire. The outbreak was centred in the Bumba Zone of the Equateur Region and most of the cases were recorded within a radius of 70 km of Yambuku, although a few patients sought medical attention in Bumba, Abumombazi, and the capital city of Kinshasa, where individual secondary and tertiary ...

A rigorous non-existence proof for runaway solutions in the finite-size model of the electron is given. Since a consistent point limit, such as the Lorentz-Dirac equation claims to be, should not exhibit features which are completely missing in the more general theory of finite extension, it is proposed that the point-like approximation of the finite-size theory be the integrodifferential formu...

In 1976 (the first year in which most of the refugees from Vietnam, Cambodia, and Laos had an opportunity to complete a full year of employment) about 56,500 individuals were reported with earnings covered under the old-age, survivors, disability, and health insurance (OASDHI) pr0gram.l This group represented about 42 percent of the 134,000 Indochina refugees who had had a social security numbe...
