30 Jul 2002TL;DR: A relief master is formed by assembly of previously molded, machined, or otherwise fabricated relief structures as discussed by the authors, which can then be used as a pattern for diverse surface replication processes, including the fabrication of durable metal mold faces for casting, embossing, compression molding, and injection molding of complex patterned surfaces.
Abstract: A relief master is formed by assembly of previously molded, machined, or otherwise fabricated relief structures. The relief structures may be quite small and include a relief geometry, i.e., a topology of interest, and a positioning feature. The relief structures are mounted on a rigid (e.g., metal) substrate that includes a plurality of positioning features complementary to the positioning features in the relief structures. The relief master is assembled through selective application and positioning of the small-scale relief structures, and can then be used as a pattern for diverse surface replication processes, including the fabrication of durable metal mold faces for casting, embossing, compression molding, and injection molding of complex patterned surfaces.

TL;DR: An overview of the design of the epidemiological track, especially of its two first waves, is given, expected to provide information that will inform the development of evidence‐based methods and strategies to prevent theDevelopment of gambling problems.
Abstract: Swelogs (Swedish Longitudinal Gambling Study) epidemiological (EP-) track is a prospective study with four waves of data-collection among Swedish citizens aged 16–84 years at baseline. The major objectives of this track are to provide general population estimates of the prevalence and incidence of problem and at-risk gambling and enable comparisons with the first Swedish national study on gambling and problem gambling (Swegs) conducted in 1997/1998. The overall study (Swelogs) comprises three tracks of data collection; one epidemiological, one in-depth and one follow-up. It is expected to provide information that will inform the development of evidence-based methods and strategies to prevent the development of gambling problems. This paper gives an overview of the design of the epidemiological track, especially of its two first waves. The baseline wave, performed between October 2008 and August 2009, included 8165 subjects, of whom 6021 were re-assessed one year later. A stratified random sampling procedure was applied. Computer-supported telephone interviews were used as the primary method. Postal questionnaires were used to follow-up those not reached by telephone. The response rate was 55% in the first wave and 74% in the second. The interview and questionnaire data are supplemented by register data. © 2014 The Authors.

TL;DR: In this article, it was demonstrated that the aerobic degradation of municipal solid waste (MSW) within a landfill can significantly increase the rate of waste decomposition and settlement, decrease the methane production and leachate leaving the system, and potentially increase the operational life of the site.
Abstract: Municipal solid waste (MSW) landfills worldwide are experiencing the consequences of conventional landfilling techniques, whereby anaerobic conditions are created within the landfilled waste. Under anaerobic conditions within a landfill site slow stabilization of the waste mass occurs, producing methane, (an explosive ‘green house’ gas) and leachate (which can pollute groundwater) over long periods of time. As a potential solution, it was demonstrated that the aerobic degradation of MSW within a landfill can significantly increase the rate of waste decomposition and settlement, decrease the methane production and leachate leaving the system, and potentially increase the operational life of the site. Readily integrated into the existing landfill infrastructure, this approach can safely and cost-effectively convert a MSW landfill from anaerobic to aerobic degradation processes, thereby effectively composting much of the organic portions (one of the potentially polluting elements in a conventional landfill site) of the waste. This paper summarizes the successful results of two separate aerobic landfill projects located in Georgia (USA) and discusses the potential, economic and environmental impacts to worldwide solid waste management practices.

TL;DR: Fiber Bragg gratings with greatly enhanced thermal stability have been fabricated by the use of femtosecond laser pulse irradiation on optical fibers with relaxed residual stress, through using high temperature annealing treatment.
Abstract: Fiber Bragg gratings with greatly enhanced thermal stability have been fabricated by the use of femtosecond laser pulse irradiation on optical fibers with relaxed residual stress, through using high temperature annealing treatment. The grating reflectivity and resonant wavelength can be maintained for periods up to 20 hours using isothermal measurements and temperatures up to 1200 °C. No hysteresis was observed in the wavelength response when the gratings were annealed and the temperature cycled repeatedly between room temperature and 1200 °C.

TL;DR: The presence of 4-isopropenylphenol in the pyrolysates of the bog-body tissues provides evidence that their preservation involves reactions of amino acids with sphagnum acid, and possibly other agents derived from the peat.
Abstract: Flash pyrolysis-gas chromatography/mass spectrometry (py-GC/MS) was used to assess the quality and mechanism of protein preservation in the tissue of Iron Age bog bodies from Lindow, UK, and south-eastern Drenthe, The Netherlands. Abundant pyrolysis products of the fresh skin tissue, including 2,5-diketopiperazines of Pro-Gly, Pro-Ala, Pro-Val, Pro-Pro and Hyp, were readily assigned to specific amino acid or dipeptide moieties. Comparison of the pyrolysates of the bog-body tissues with that of modern samples revealed qualitative similarities suggesting good preservation of the collagen and non-collagenous proteins in the ancient tissues. Examination of the pyrolysates of samples of fresh calf skin, which had been treated with various vegetable tanning agents, clearly revealed markers of non-hydrolysable tannins including 1,2-benzenediol, 1,3-benzenediol and 1,2,3-benzenetriol, although chromatographic quality inevitably diminished with increasing functionalization of the compounds. Such markers were not detected in the pyrolysates of the bog-body tissues. Instead 4-isopropenylphenol, a characteristic pyrolysis product of Sphagnum moss, was detected in both solvent-extracted and base-treated samples of tissue. The presence of 4-isopropenylphenol in the pyrolysates of the bog-body tissues provides evidence that their preservation involves reactions of amino acids with spagnum acid, and possibly other agents derived from the peat. The study constitutes the first chemical characterization of the pyrolysis products of modern and ancient collagen. © 1997 John Wiley & Sons, Ltd.
