To prevent further increases in energy consumption, the government of Iran commenced energy subsidy reform in 2010. This paper investigates the fuel conservation effects of the reform in Iran using a homothetic translog cost function that provides estimates of the own- and cross-price elasticities of fuel demands. The percentage reduction in fuel demands is estimated using the likely effect of ...

While the wealth effect from a capital influx would induce households to buy more dirty fuel, they might simultaneously reduce their purchases depending on the degree of substitutability with clean fuels and other consumption. This substitution effect will not necessarily dominate the wealth effect, unless dirty fuels are an inferior good. However, a capital increase could also cause labor to b...

reduction of exhaust emissions is a major research task in diesel engine development in view of increasing concerns regarding environmental protection and stringent exhaust gas regulations. simultaneousreduction of nox emissions and particulate matter is quite difficult due to the soot/nox trade-off and isoften accompanied by fuel consumption penalties. towards this aim, automotive engineers ha...

in this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. investigating internal consumption, degradation and site ambient con...

The core objective of this paper is to analyse the impact of changes in fuel intensity and car size on energy demand of passenger cars in EU-15 countries. Of special relevance in this context is how the rebound effect due to the change in car fuel intensity and car size (average engine power) affects the energy conservation effect. Lower fuel intensity reduces the cost of car travel, and may le...

In the monitoring of pollutants in an aquatic environment, it is important to preserve water quality safety. Among the available analysis methods, the microbial fuel cell (MFC) sensor has recently been used as a sustainable and on-line electrochemical microbial biosensor for biochemical oxygen demand (BOD) and toxicity, respectively. However, the effect of the background organic matter concentr...

In the conversion of fuel in the Tehran Research Reactor core from Highly- Enriched Uraniutn to Low-Enriched Uranium fuel neutronics analysis, thermal hydraulic calculations and kinetic performance of the core have to be studied. In this study, static and dynamic core performance for HEU and LEU fuels were investigated. In static conditions, two groups of neutron flux distributions in axia...

There are several obstacles to the commercialization of PEM fuel cells.  One of the reasons is that the presence of carbon monoxide (CO) in the reformatted fuel, even at a very small scale, decreases the fuel cell performance. The aim of this paper is to investigate the effect of CO in reformatted fuel on PEM fuel cell performance. For this purpose, a steady state, one-dimensional and non-isoth...

The rebound effect is the causal impact of an increase in fuel efficiency on the demand for car kilometres. The rebound effect has been studied in several different sectors (for a survey, see Greening et al. (2000)). Some recent studies have extensively focused on passenger transportation using macro data (see, Small and Van Dender (2007); Hymel et al. (2010)). However, the rebound effect is es...
