Rayleigh’s dissipation function at work

Fluctuation and dissipation of work in a Joule experiment.

We elucidate the connection between various fluctuation theorems by a microcanonical version of the Crooks relation. We derive the microscopically exact expression for the work distribution in an idealized Joule experiment, namely, for a convex object moving at constant speed through an ideal gas. Analytic results are compared with molecular dynamics simulations of a hard disk gas.

Tidal dissipation at arbitrary eccentricity and obliquity

Expressions for tidal dissipation in a body in synchronous rotation at arbitrary orbital eccentricity and obliquity are derived. The rate of tidal dissipation for a synchronously rotating body is compared to that in a body in asymptotic nonsynchronous rotation. © 2007 Elsevier Inc. All rights reserved.

Cleaning at Home and at Work in Relation to Lung Function Decline and Airway Obstruction.

RATIONALE Cleaning tasks may imply exposure to chemical agents with potential harmful effects to the respiratory system, and increased risk of asthma and respiratory symptoms among professional cleaners and in persons cleaning at home has been reported. The long-term consequences of cleaning agents on respiratory health are, however, not well described. OBJECTIVES This paper aims to investiga...

Fixed-term work and violence at work.

OBJECTIVES This study investigated the effect of a fixed-term job contract on encounters of violence at work. We assumed that fixed-term employees encountered more violence or threats of violence at their work than permanent employees. METHODS This study is based on 3 large statistical data sets: (a) the Work and Health surveys carried out by the Finnish Institute of Occupational Health in 19...
