a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
The unjust distributional consequences of climate change, and its potentially negative aggregate effect on economic growth and welfare are two reasons to be concerned about climate change. Our knowledge of the impact of climate change is incomplete. Monetary valuation is difficult and controversial. The effect of other developments on the impacts of climate change is largely speculative. Noneth...
Conventional benefit-cost analysis incorporates the normally reasonable assumption that the policy or project under examination is marginal. Among the assumptions this entails is that the policy or project is small, so the underlying growth rate of the economy does not change. However, this assumption may be inappropriate in some important circumstances, including in climate-change and energy p...
This article measures the extent to which prices exceed marginal costs in the U.S. natural gas distribution market during the period 1991-2007. We find large departures from marginal cost pricing in all 50 states, with residential and commercial customers facing average markups of over 40%. Based on conservative estimates of the price elasticity of demand these distortions impose hundreds of mi...
Carbon sequestration is believed to “buy time” for technical change in the energy sector. To assess rigorously this widespread argument, we build an intertemporal optimization model where both abatement of fossil fuel emissions and biomass sequestration can be used to mitigate climate change. We confirm that permanent sequestration, if feasible, can be a cost-effective part of an overall climat...
the caspian sea contains great resources of oil and gas. the caspian sea is a 700- mile- long body of water in central asia, land located between azerbaijan, iran, kazakhstan, russia and turkmenistan. iran was challenges and opportunities in the caspian region. key question in this thesis includes three section that first question, opportunities of iran in the caspian region, second question ch...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
Providing enough microalgae biomass is required for various applications in sectors such as food, medicine and energy. The biomass resources such as land, water, nutrient and carbon dioxide are essential in cultivation feasibility study for biomass production as well as cost benefits. The aims of this research is therefore, site assessment and prioritization of potential site locations, carbon ...
The estimation of the value of carbon emissions has become a major research and policy topic since the establishment of the Kyoto Protocol. The shadow price of CO2 provides information about the marginal abatement cost of this pollutant. It is an essential element in guiding environmental policy issues, since the CO2 shadow price can be used when fixing carbon tax rates, in environmental cost-b...
In this mentioned study for sea water treatment ceramic composites were made from natural alumina and adsorbent active ingredients. According to the experimental results, filters along with active agents have acceptable effects on drinking water parameters and contaminants in compare with 1053 ISIRI standard. Modular set up was made for sea water treatment tests. Water flowrate after filtration...
