in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
Background and Objectives: Contamination of storage wheat to zearalenone producer molds represents a significant hazard to consumer health and has thus received increasing attention from food safety authorities and legislators. Various species of Fusarium genus are producer of different mycotoxins including zearalenone at certain conditions. These mycotoxins can enter into the human food and an...
We examine the effects of coordinated trade-tax reforms and isolated tariff reforms on market access, government revenue and welfare for a small monetary economy, under the assumption that a certain fraction of purchases of each good must be financed with cash held in advance. Moreover, we allow for this fraction of purchases to vary across markets, in the sense that the required amount of mone...
We provide a graphical illustration of how standard consumer and producer theory can be used to quantify the welfare loss associated with inefficient pricing in insurance markets with selection. We then show how this welfare loss can be estimated empirically using identifying variation in the price of insurance. Such variation, together with quantity data, allows us to estimate the demand for i...

The advent of nearly ubiquitous information infrastructures has led many to predict that one effect of electronic markets will be the bypassing of intermediaries in electronic markets. The ability of electronic networks to reduce transaction costs is the theoretical cause of this supposed trend. We suggest that, on the contrary, not only is it likely that widely available information infrastruc...
This paper examines the incentive of atomistic agricultural producers within a specific geographical region to differentiate and collectively market products. We develop a model that allows us to analyze the market and welfare effects of the main types of real-world producer organizations, using it to derive economic insights regarding the circumstances under which these organizations will evol...
While it is crucial to understand the factors that determine the biodiversity of primary producer communities, the relative importance of bottom-up and top-down control factors is still poorly understood. Using freshwater benthic algal communities in the laboratory as a model system, we find an unimodal relationship between nutrient availability and producer diversity, and that increasing numbe...
in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...
Recently, sustainable development and policy on improving the quality of the environment have attracted economists. The use of fossil fuel tax and subsidies to research and development are among the tools that can reduce air pollution by creating economic incentives and relative price adjustments. In this regard, the present study uses a Computable General Equilibrium (CGE) model to examine env...
