In this research, gasoline vapours including Benzene, Toluene, Xylene (BTX) and Total Volatile Organic Compounds (TVOCs) emitted from vent pipes of underground storage tanks (USTs) were measured at six gas stations in Tehran. Thereafter, gas station No. 29 was selected as a pilot station and equipped with a vapour control system. The vapours were measured during the summer of 2013 and winter of...

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. ...

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...

This paper gives a case of large Sub-Station Clean Development Mechanism (CDM) Project to analyze CDM project’s influence on India’s Sustainable Development. SF6 gas is being extensively used in circuit breakers. SF6 gas has the highest Global warming potential which is 23900 times of Carbon Dioxide. Extensive Survey of SubStation using SF6 circuit breaker has been done in a sample state of Ind...

natural convection heat transfer from a tube bundle in the indirect water bath heaters is investigated. a computer-code is used for the solution of the governing equations of mass, momentum and energy transfer based on the simple-c algorithm. simulations are carried out for the gas pressure station heater of kermanshah city with various tube bundle arrangements. in order to validate the numeric...

Benzene is a ubiquitous environmental pollutant and an important industrial chemical present in both gasoline and motor vehicle emissions. Occupational human exposure to benzene occurs in the petrochemical and petroleum refining industries as well as in gas-station workers, where it can lead to benzene poisoning (BP), but the mechanisms of BP are not completely understood. In Brazil, a signific...
