BACKGROUND The present study aimed to assess the prevalence of common mental disorders (CMDs) by occupation in a representative sample of the English adult population. Another aim was to examine whether the increased risk of CMD in some occupations could be explained by adverse work characteristics. Method We derived a sample of 3425 working-age respondents from the Adult Psychiatric Morbidity ...
OBJECTIVE Work environment is said to influence cardiovascular risk. We assessed whether nature of occupation affects risk of sudden cardiac death (SCD) in the general population. METHODS In the ongoing, prospective Oregon Sudden Unexpected Death Study (catchment population 1 million), working-age SCD cases (18-65 years) were compared with controls who died from any cause. Usual occupation ob...
BACKGROUND There has been widespread concern that the increasing incidence of asthma observed during the late 1980s might have arisen because of environmental pollution, and in particular vehicle pollution. The General Practice Morbidity Survey in 1991/92 (MSGP4) collected data on occupation, employment status, and smoking habit linked individually to each patient record. OBJECTIVES To examin...
Byrd Glacier has one of the largest ice catchment areas in Antarctica, delivers more ice to the Ross Ice Shelf than any other ice stream, and is the fastest of these ice streams. A force balance, combined with a mass balance, demonstrates that stream flow in Byrd Glacier is transitional from sheet flow in East Antarctica to shelf flow in the Ross Ice Shelf. The longitudinal pulling stress, calc...
ABSTRACT Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome. It affects women more than men. CTS occurs primarily idiopathically or secondary to other diseases. A square wrist dimension is a risk factor for the development of CTS. This study is done for the evaluation of the relationship between the wrist ratio and CTS. 60 patients (54 females and 6 males) with idiopat...
This paper considers the reported attack ratio arising from outbreaks of influenza in enclosed societies. These societies are isolated from the wider community and have greater opportunities for contact between members which would aid the spread of disease. While the particular kind of society (prison, care home, school, barracks, etc.) was not a significant factor in an adjusted model of attac...
The rheological behaviour of a dense granular bed under dynamic conditions is investigated by simulating flow in the FT4 powder rheometer using Discrete Element Method. distribution prevailing stresses and strain rates bed, their dependence on material properties blade operational conditions, are analysed. shear stress was found to be approximately constant radial direction along but dissipates...
The regime of sediment transport in the Jingjiang Reach has significantly changed from quasi-equilibrium to sub-saturation since the impoundment of the Three Gorges Dam (TGD), and vertical profiles of suspended sediment concentration (SSC) have changed accordingly. Vertical profiles of SSC data measured at three hydrological stations in the Jingjiang Reach (Zhicheng, Shaishi, and Jianli), befor...
