BACKGROUND Psychiatric epidemiology has revealed a number of associations between gender, socioeconomic status, and psychiatric disorders. AIMS To examine psychosocial conditions on and off the job in relation to psychological ill health. METHODS Longitudinal design with 24 year follow up of employed persons (190 women, 177 men). Interview and questionnaire data on work and leisure conditio...

BACKGROUND Employees with physically heavy work have an increased risk of musculoskeletal disorders leading to reduced work ability. AIMS To investigate if a high level of musculoskeletal pain or pain-related fear of movement was associated with low productivity among employees with physically heavy work and differing work ability levels. METHODS The study was conducted at a Danish producti...

This study presents a structure-function analysis of the mammalian left ventricle and examines the performance of the cardiac capillary network, mitochondria, and myofibrils at rest and during simulated heavy exercise. Left ventricular external mechanical work rate was calculated from cardiac output and systemic mean arterial blood pressure in resting sheep (Ovis aries; n = 4) and goats (Capra ...

background: sediments are inseparable fractions of wetland ecosystems that work as a his-torical archive in the process of recording heavy metal aggregation changes. this study was carried out for assessing co, ni, and zn in sediment samples of mighan wetland using geo-accumulation index in 2013. methods:the sediment samples were taken from 11 stations. the samples were subjected to bulk digest...

BACKGROUND There are theoretical grounds to suspect that heavy lifting at work is an important risk factor for ischemic heart disease (IHD). However the relationship has not been sufficiently acknowledged by empirical studies. Positive and statistically significant associations have been found in studies that utilize self-reported exposure data. Such studies are, however, prone to reporting bia...

In a recent series of papers we have shown that including heavy quarks in the dibaryon sector can lead to configurations stable against decay into two baryons. In this study we extend our previous work by a study of all the physical Q q [Q denotes a heavy quark and q denotes a member of the SU(3)~ triplet representation] systems in a solvable chromomagnetic model. We propose a number of new hea...

The nonmesonic decay of the Λ–hyperon has been investigated by observation of delayed fission from heavy hypernuclei produced in proton – U collisions at Tp=1.9 GeV. The lifetime of heavy hypernuclei with masses A≈220 obtained in the present work, i.e. τΛ = [138± 6(stat.)± 17(syst.)] ps, is the most accurate result for heavy hypernuclei produced in proton and antiproton induced collisions on a ...
