Bangladesh is still a low urbanized country although it experienced a rising trend in the level of urbanization throughout the twentieth century and had a remarkably high urban growth immediately after its independence in 1971. The country recorded the highest ever annual average growth rate (9.04) and percentage of interval variation (137.57%) in an urban population in 1974; thereafter, growth...

This paper investigates the impact of government size on economic growth in selected economies of the MENA countries by using a non-linear panel data approach over the period 1990-2011. The estimation results of Panel Smooth Threshold Regression model show that when the level of government consumption is very large, the positive impact of labor force on growth is intensified. On the other hand,...

in the present study, air quality analyses for ozone (o3) were conducted in ahvaz, a city in the south of iran. the measurements were taken from 2009 through 2010 in two different locations to prepare average data in the city. relations between the air pollutant and some meteorological parameters were calculated statistically using the daily average data. the wind data (velocity, direction), re...

introduction: the development of an appropriate model for the quality control of an industrial wastewater treatment system can save the time as well as the cost. this study was performed to determine an appropriate model in order to predict the cod and tkn parameters by bod5 and nh4+ in the meybod industrial estate waste water treatment plant (wwtp). methods: this descriptive – analytical study...

the use of remote sensing techniques as a suitable solution to estimate the levels of species diversity is of high importance for the sustainable management of forests. in order to investigate the potential of using sensor data from landsat 7 etm+ to estimate species diversity in the zagros forests, digital data related to the august 7, 2002 from forests in the qalajeh kermanshah province were ...

this paper presents a new index of financial stress which is constructed by macro data from different financial markets (including banking sector and also housing, foreign exchange and stock markets). the proposed approach has been applied to the iranian economy based on the available quarterly time series, covering the period 1991(1)–2008(2). the paper explains how the selected components capt...

regarding the important role of health in economic growth and development, the purpose of the present paper is to investigate the impact of life expectancy, as the most important indicator of health, on economic growth in iran during 1965-2009. the estimated smooth transition regression (str) model supports a nonlinear threshold behavior in the relationship between life expectancy and economic ...

A new probability distribution is proposed in this paper. This has support on the interval and was obtained after transforming random variable with exponential distribution. The mode, quantile function, median, ordinary moments density function belongs to family of distributions are demonstrated. maximum likelihood method used obtain parameter estimate. regression model for median also proposed...
