Reducing C02 emissions for addressing climate change concerns is becoming increasingly important as the C02 concentration in the atmosphere has increased rapidly since the industrial revolution. Many mitigation methods, including C02 sequestration and novel C02 utilization, are currently-under investigation. Most of these processes require C02 in a concentrated form. However the C02 from large ...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

This study, which developed a laboratory prototype of a hermetic C02 compressor, was motivated by three primary factors. First, the C02 cycle is important because of global concern about ozone depletion and global wanning. Second, the leak tightness, efficiency, size and weight of hermetic motor-driven compressors make them preferable to open-type compressors for conventional residentiallcommer...

The behavior of exchange rate in various exchange markets is not seemingly predictable, while there are different forecasting methods to do so. One of these methods is to use fractals to identify exchange rate behavior. This paper has made attempts to explore the properties of fractals in Iran’s exchange market in order to it can predict and analyze the trend of exchange rate. Accordingly, th...

Rice (Oryza sativa cv. Jindao 1187) was grown in open-top chambers which contained ambient and enriched C02. C02 elevation stimulated rice tillering during early vegetative stage. However, panicle dry weight per plant did not change at maturity stage. Root biomass was enhanced by high COz. Root / shoot ratio was increased under high C02 at maturity, indicating more carbon allocation to the belo...

factor demand behavior such as energy demand has an important role in the economic analysis. this issue is a major concern in the developing countries (e.g. iran) which are benefited from vast energy resources. in this paper, the third generation of factor demand models is used to analyze the behavior of capital adjustment in the iranian manufacturing industries. the dataset covers the two-digi...

Over the last decades overheating in buildings has become a major concern. The situation is expected to worsen due current rate of climate change. Many efforts have been made evaluate future thermal performance and cooling technologies. In this paper, term “climate change resistivity” strategies defined, calculation method provided. A comprehensive simulation-based framework then introduced, en...

abstract main objective of this paper is the investigation the effect of support policies of government on income risk of poultry producers in iran for the 1989-2006. ccv index was used to investigate amount of variation that cause each support policies (market price support, support of agricultural inputs, outputs insurance) on income risk variation of producers. the results of this study show...
