The objective of this study was to evaluate cancer mortality in pulp and paper industry workers exposed to chlorinated organic compounds. We assembled a multinational cohort of workers employed between 1920 and 1996 in 11 countries. Exposure to both volatile and nonvolatile organochlorine compounds was estimated at the department level using an exposure matrix. We conducted a standardized morta...

BACKGROUND Occupational exposure to silica dust occurs in many workplaces and is well known to cause silicosis. However, the link between silica exposure, silicosis and other diseases is still disputed. AIMS To evaluate cause-specific mortality in a cohort of Italian silicotics. METHODS The cohort included 2034 male compensated for silicosis between 1943 and 1986, alive on 1 January 1987 an...

This investigation studies cause-specific mortality of art glass workers employed in 17 industrial facilities in Tuscany, Italy. A cohort of 3,390 workers employed for at least 1 year was enumerated from company payrolls. Follow-up was between the start of employment in each factory and 31 December 1993. The cause-specific expected mortality was computed relative to Tuscany rates and specified ...

The objective of the present study was to examine if the mortality due to tuberculosis and cancer in the lungs was elevated in a cohort of 200 male whetstone cutters. 1955-1995 death certificate-based mortality data on the cohort were available, and the data were reviewed in the present study for mortality due to the two diseases to calculate standardized mortality ratios (SMR) in reference to ...

Standard metabolic rate (SMR) and maximum metabolic rate (MMR) typically vary two- or threefold among conspecifics, with both traits assumed to significantly impact fitness. However, the underlying mechanisms that determine such intraspecific variation are not well understood. We examined the influence of mitochondrial properties on intraspecific variation in SMR and MMR and hypothesized that i...

Sensorimotor rhythms (SMR, 8-15 Hz) are brain oscillations associated with successful motor performance, imagery, and imitation. Voluntary modulation of SMR can be used to control brain-machine interfaces (BMI) in the absence of any physical movements. The mechanisms underlying acquisition of such skill are unknown. Here, we provide evidence for a causal link between function of the primary mot...

STUDY OBJECTIVE This study aimed to examine whether the high mortality in lower salaried men in Norway was related to an inflow into this group of unskilled workers with high mortality. DESIGN Individual information on occupation was derived from the 1970 and the 1980 censuses and linked to mortality data for the period 1980-5 by the official, individual identification numbers. PARTICIPANTS...

OBJECTIVES To evaluate mortality due to lung cancer, silicosis, renal cancer, renal disease and other causes among German porcelain production workers potentially exposed to crystalline silica. METHODS Seventeen thousand six hundred forty-four medical surveillance participants (1985-1987) were followed through 2005 for mortality. Cause-specific Standardized Mortality Ratios (SMR) and 95% conf...

Digital data is projected to double every two years creating the need for cost effective and performant storage media [4]. Hard disk drives (HDDs) are a cost effective storage media that sit between speedy yet costly flashbased storage, and cheap but slower media such as tape drives. However, virtually all HDDs today use a technology called perpendicular magnetic recording, and the density achi...
