Economic research has developed estimates of the heterogeneity of the value of statistical life (VSL) on dimensions such as individual age, income, immigrant status, and the nature of the risk exposure. This paper examines the empirical evidence on the heterogeneity of VSL and explores the potential implications for the valuation of regulatory policies. Previously, the U.S. Environmental Protec...

Suspended molecules of DNA are used as substrates for deposition of various metals by DC sputtering. The result is the formation of metallic nanowires, most with diameters of 10-50 nm. Homogeneous wires have been observed when a proper metal is chosen. For the first time, these DNA-templated nanowires are fabricated on substrates conducive to transmission electron microscopy. TEM and SEM analys...

We report an innovative strategy to obtain cylindrical nanowires combining well established and low-cost bottom-up methods such as template-assisted nanowires synthesis and electrodeposition process. This approach allows the growth of single-layer or multi-segmented nanowires with precise control over their length (from few nanometers to several micrometers). The employed techniques give rise t...

What, if anything, are the implications of the happiness economics literature on competition policy? This Article first examines whether competition policy should promote (or at least not impede) citizens' opportunities to increase well-being. It next surveys the happiness literature on five key issues: (i) What constitutes well-being; (ii) How do you measure well-being; (iii) What increases we...

agriculture as one of the major economic sectors of iran, has an important role in gross domestic production by providing about 14% of gdp. this study attempts to forecast the value of the agriculture gdp using periodic autoregressive model (par), as the new seasonal time series techniques. to address this aim, the quarterly data were collected from march 1988 to july 1989. the collected data w...

background & objectives: cancer is a serious problem for human being and is becoming a serious problem day-by-day .a prerequisite for any therapeutic modality is early diagnosis. automated cancer diagnosis by automatic image feature extraction procedures can be used as a feature extraction in the field of fractal dimension. the aim of this survey was to introduce a quantitative and objectiv...

in order to evaluate of biological fertilizers and micronutrient elements effects on yield and some agronomic traits in rapeseed (brassica napus l.), an experimental was performed as factorial arrengement based on randomized complete blocks design with three replications in 2012-13 in research station of shahid chamran university of ahvaz, iran. in this experiment, micronutrient elements were i...
