I tested the hypothesis that early season herbivory by leaf-chewing insects affects distribution, densities, and survivorship of late-feeding, leaf-mining insects; early chewing may physically and chemically alter quality of leaves for later leaf miners on the shared host plant, Quercus emoryi. Proportions of intact leaves and leaves damaged by native leaf chewers on six control and six experim...

Nationalisation of the coal industry by the 1945 Labour Government provided Britain with a unique opportunity for preventing the disablement of coal miners. At that time several thousand miners received disability benefits each year for pneumoconiosis in South Wales alone, and the Medical Research Council had started an important series of investigations into the relationships between dust expo...

Bitcoin is a cryptocurrency based in peer-to-peer network that uses a blockchain. To maintain the blockchain without trusted third parties, a player called a miner proves that he has completed a proofof-work. As the difficulty of proof-of-work is increasing, mining pools, consisting of a number of miners, have become major players compared with solo miners. Most mining pools consist of a manage...

The potential of coal mine dust to cause disabling pneumoconiosis has long been recognised, but research now suggests that pneumoconiosis is not the only respiratory hazard of coal mining.Over the last 30 years evidence has accumulated that miners also experience an excess of chronic obstructive pulmonary disease (COPD), and this has led the British Government to classify chronic bronchitis and...

The mining process in blockchain requires solving a proof-of-work puzzle, which is resource expensive to implement in mobile devices due to the high computing power and energy needed. In this paper, we, for the first time, consider edge computing as an enabler for mobile blockchain. In particular, we study edge computing resource management and pricing to support mobile blockchain applications ...

Dissatisfaction with work boot design is common in the mining industry. Many underground coal miners believe their work boots contribute to the high incidence of lower limb injuries they experience. Despite this, the most recent research to examine underground coal mining work boot satisfaction was conducted over a decade ago. This present study aimed to address this gap in the literature by as...

BACKGROUND Dehydration is a health risk for miners in tropical regions of Australia. However, it is not known whether dehydration poses a health risk to miners working in temperate regions of Australia. METHODS A cross-sectional study of 88 miners from two underground mines was undertaken in south-eastern New South Wales, Australia. Participants had their height, weight, waist circumference a...

Little is known about the current health status of US metal and nonmetal (MNM) miners, in part because no health surveillance systems exist for this population. The National Institute for Occupational Safety and Health (NIOSH) is developing a program to characterize burden of disease among MNM miners. This report discusses current knowledge and potential data sources of MNM miner health. Recent...
