this study has investigated the long-run and short-run effects of relative productivity on real exchange rate using annual time series data of iran and its major trade partners over the period 1980-2005. to analyze such effect which refers to the balassa-samuelson effect, this research uses auto-regressive distributed lags (ardl) method, to deal with dynamics of the relationship between product...

increment. it is categorized based on genetic aberrations. some of these genetic disorders can determine minimal residual diseases (mrd) and prognosis of aml patients. wilms tumor (wt1) over expression is found in aml patients. the aim of this study was to determine the frequency of wt1 over expression in aml pediatric cases in north -east of iran. materials and methods: this retrospective stud...

We show that for any real number, the class of real numbers less random than it, in the sense of rK-reducibility, forms a countable real closed subfield of the real ordered field. This generalizes the well-known fact that the computable reals form a real closed field. With the same technique we show that the class of differences of computably enumerable reals (d.c.e. reals) and the class of com...

This paper describes two vision-based techniques for the navigation of an aircraft relative to an airborne target using only information from a single camera fixed to the aircraft. These techniques are motivated by problems such as “see and avoid”, pursuit, formation flying, and in-air refueling. By applying an Extended Kalman Filter for relative state estimation, both the velocity and position...

In the present study, a simple electrochemical sensor for trace determination of Hg(II) ions in aqueous solutions was introduced. The proposed sensor was designed by incorporation of the 4-methyl-piperidine-carbodithioate capped gold nanoparticles (GNPs) into the carbon paste electrode (CPE), which provides a remarkably improved sensitivity for stripping voltammetric determination of Hg(II). Di...

In this work, an environmentally friendly sample pre-treatment method, Ultrasound Assisted Surfactant Enhanced Emulsification Microextraction (UASEME) followed with spectrofluorimetry was performed for determination of oxadiazon residues in water samples. After the determination of the most suitable extraction solvent and its volume, other parameters such as type and concentration of surfac...
