Forty-two noise exposures and 164 whole-body (WBV) and hand-arm (HAV) vibration exposures were collected from 43 forestry workers in six trades employed by two forestry companies. Data were collected on 10 days over 8 weeks during various felling, logging, and log handling operations. Up to 5 volunteers were monitored for noise and vibration daily using datalogging noise dosimeters, which provi...

AIMS To evaluate an epidemiological approach to a national noise hazard surveillance strategy, and report current exposure levels in the Danish workplace. METHODS A study base of 840 companies in 10 selected high risk industries in the largest county in Denmark was identified from a national register. Noise exposure was measured among manual workers recruited from a random sample of workplace...

AIMS To test whether the risk of relapse in alcohol dependence is predicted by the subjective experience of cue exposure (CE) and/or cortisol reactivity to alcohol cues. METHODS Salivary cortisol and self-ratings of 'tension' and 'desire to drink' were measured in 32 detoxified alcohol-dependent inpatients during CE sessions conducted in the first and third week of motivation enhancement ther...

AIMS Recent studies with animal models showed that the stimulant and sedative effects of alcohol change during the adolescent period. In humans, the stimulant effects of ethanol are most often indirectly recorded through the measurement of explicit and implicit alcohol effect expectancies. However, it is unknown how such implicit and explicit expectancies evolve with age in humans during adoles...

Near-term decarbonization of aviation requires energy-dense, renewable liquid fuels. Biomass-derived 1,4-dimethylcyclooctane (DMCO), a cyclic alkane with volumetric net heat combustion up to 9.2% higher than Jet A, has the potential serve as low-carbon, high-performance jet fuel blendstock that may enable paraffinic bio-jet fuels operate without aromatic compounds. DMCO can be produced from bio...
