OBJECTIVE To investigate variations in quality of life at older ages, we take a life course perspective to analyse long-term effects of physical working conditions upon quality of life after retirement. In doing so, we study to what extent these associations are explained by individuals' health at older ages. METHOD We use administrative data and self-administered questionnaire responses from...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
As public concern mounts over exposures to ionizing radiation stemming from environmental releases of radionuclides following nuclear accidents, there is a growing need to develop reliable techniques that reconstruct exposures and doses to individuals. Especially in situations where conventional dosimeters were not in place at the time of facing to radiation exposure. In order to provide guidan...
BACKGROUND Only few studies deal with the workload of physical therapists and the health consequences, although this occupational group is quite important for the health care system in many industrialized countries (e.g. ca. 136 000 people are currently employed as physical therapists in Germany).
