  Kashan Erg is one of the most important sand dunes complexes in Iran. Due to erosive winds, always, Erg's marginal areas are faced to the transition of moving sands. So, in this research, the sand dune activity was investigated by Lancaster index. In this line, Erg's morphology map was prepared using aerial photographic, Google earth software and field observations. Then, maps of iso...

   Historically, DNA molecules have been known as the building blocks of life, later on in 1994, Leonard Adelman introduced a technique to utilize DNA molecules for a new kind of computation. According to the massive parallelism, huge storage capacity and the ability of using the DNA molecules inside the living tissue, this type of computation is applied in many application areas such as me...

In this paper, stability of slopes with a shallow foundation located on top including the shape of the failure mechanism is investigated in static and seismic states. This is a three dimensional problem which is analyzed two dimensionally because 3D analyses are complex and appropriate softwares are not available. The conventional method of bearing capacity evaluation of foundations on top of ...

Experiments were performed to measure the apneic threshold for CO2 and its fundamental properties in anesthetized rats under steady-state conditions. Breathing was detected from diaphragmatic electromyogram activity. Mechanical hyperventilation resulted in apnea once arterial PCO2 (PaCO2) had fallen far enough. Apnea was not a reflex response to lung inflation because it did not occur immediate...

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,...

‌Introduction: Spinal cord injury is one of the important unresolved problems in the medical society leading to adverse consequences, such as motionlessness and neuropathic pain. Neuropathic pain is seen in both forms of hyperalgesia and allodynia. In this study, the effects of low-level laser radiation on hyperalgesia pain have been investigated.   Material & Methods: In this experimental stu...
