Measurement of the spectral functions of vector current hadronic tau decays

CERN-LEP. A measurement of the spectral functions of non-strange $\tau$ vector current final states is presented, using 124358 $\tau$ pairs recorded by the ALEPH detector at LEP during the years 1991 to 1994. The spectral functions of the dominant two- and four-pion $\tau$ decay channels are compared to published results of $e^+e^-$ annihilation experiments via isospin rotation. A combined fit of the pion form factor from $\tau$ decays and $e^+e^-$ data is performed using different parame...

Aging of Veterans of the Union Army: Military, Pension, and Medical Records, 1820-1940

Robert W. Fogel (1997)
Publisher: ICPSR - Interuniversity Consortium for Political and Social Research
This data collection constitutes a portion of the historical data collected by the project "Early Indicators of Later Work Levels, Disease, and Death." With the goal of constructing datasets suitable for longitudinal analyses of factors affecting the aging process, the project is collecting military, medical, and socioeconomical data on a sample of white males mustered into the Union Army during the Civil War. The project seeks to examine the influence of environmental and host factors prior ...

A Study of tau decays involving eta and omega mesons

CERN-LEP. The 132 pb$^{-1}$ of data collected by ALEPH from 1991 to 1994 have been used to analyze $\eta$ and $\omega$ production in $\tau$ decays. The following branching fractions have been measured: $$\begin{eqnarray} B(\tau^-\to\nu_{\tau}\omega h^-) = (1.91 \pm 0.07 \pm 0.06) \times 10^{-2},\\ B(\tau^-\to\nu_{\tau}\omega h^-\pi^0) = (4.3 \pm 0.6 \pm 0.5) \times 10^{-3},\\ B(\tau^-\to\nu_{\tau}\eta K^-) = (2.9^{+1.3}_{-1.2} \pm 0.7) \times 10^{-4},\\ B(\tau^-\to\nu_{\tau}\e...

Dutch Parliamentary Election Panel Study, 1981-1986

Eijk, C. van; Irwin, G.A.; Niemoeller, B. (1997)
Publisher: ICPSR - Interuniversity Consortium for Political and Social Research
This panel study was conducted within the framework of the Dutch Parliamentary Election Studies. The survey was administered in five waves. Three waves were conducted in 1981, two before the election of May 26 and one afterward. The fourth wave occurred in the fall of 1982 and the final wave in 1986. The purpose of this collection was to assess electoral change in the Netherlands. Main topics covered in the first wave included political interest, national problems of importance to the respond...

Risk assessment in the Netherlands

Publisher: Universit├Ąt Stuttgart
Embargo end date: 2016/03/31
The Dutch approach to risk assessment is defined in the National Plan for Environmental Protection Policy (NMP) of 1988. The goal is the present and future protection of humans, animals, plants, the ecosystem, and property through measures designed to provide for a sustainable development. The safety goals are defined in "Premises for Risk Management," an annex to the NMP, in 1989. Safety goals are determined with quantitative values. Maximum permitted risks are differentiated from negligible...
