A Lagrangean and set of Feynman rules are presented for non-relativistic QFT’s with manifest power counting in the heavy particle velocity v. A régime is identified in which energies and momenta are of order Mv. It is neither identical to the ultrasoft régime corresponding to radiative processes with energies and momenta of order Mv2, nor to the potential régime with on shell heavy particles an...

Life expectancy at birth now stands at 79 years in France, according to vital registration data. Mortality data for the Ancien Régime can be found in the parish registers in which local priests recorded baptisms, marriages and burials. They are found in a few parishes from the end of the 15th century, and were brought into general use by a royal decree of 1667. The demographers who first began ...

ENEPRI Research Reports present the findings and conclusions of research undertaken in the context of research projects carried out by a consortium of ENEPRI member institutes. This report was produced by the ANCIEN project, which focuses on the future of long-term care for the elderly in Europe. Funding for the project is received from the European Commission under the 7th Framework Programme ...

The stable isotopic compositions of nitrogen and carbon in animal tissues reflect diet. However, factors other than diet can also affect these stable isotope ratios, leading to misinterpretations of diet composition. To test the hypothesis that variation in metabolic rate alters the isotopic compositions of tissues, deer mice (Peromyscus maniculatus (Wagner, 1845)) were kept at three temperatur...
