background: gasoline station workers are exposed to volatile organic compounds such as benzene, toluene, ethylbenzene and xylene (btex). objectives: to determine the level of exposure to btex compounds among gasoline station workers and measure the roadside concentrations of these compounds in the inner and outer areas of bangkok, thailand. methods: 49 workers at 6 gasoline stations in the inne...

Owing to the unreasonable layout problem and the excessive number of gas station in some regions of China, this paper attempts to discuss the principle of rationality and related factors for the gas station layout. In determining the relationship between the number of stations and motor vehicle demand, this paper simulates the vehicle’s selection of price by using Starlogo simulation platform. ...

The March 2011 nuclear accident at the Fukushima Daiichi nuclear power station affected both shortand long-term energy-security in Japan, resulting in crisis-driven, ad hoc energy policy and, because of the decision to shutter all nuclear reactors, increased the country’s demand for fossil fuels, primarily natural gas. However, the effects of the accident on energy security were not restricted ...

This paper addresses systematic variations in the interpretation of indefinites and plurals when appearing within prepositional phrases and other spatial expressions. We show that these variations are explained when spatial processes in semantics locate the sets associated with properties and other setbased denotations of nominals. Starting with spatial indefinites we consider contrasts like th...

To comprehend spoken language, listeners must segment continuous speech into individual words. In cases where /s/ occurs on both sides of a word boundary (e.g., gas station) segmentation might be difficult because the two s-sounds blend together into one long s-sound. We report a series of experiments that examined how listeners segment such sequences, focusing on the contribution of lexical kn...

combined cycle performance can be improved by improving the performance of gas turbine based topping cycle. amongst various options the effective cooling of gas turbine blade for realizing the higher turbine inlet temperatures is one of the attractive options. the present paper deals with the thermodynam-ic analysis of advanced technology gas/steam combined cycle based power plant having closed...
