before constitution revolution, advocacy in our country governed by islamic law and lawyers introduced as a free profession in means of that law. after that revolution the government promulgated some rules for its regulation as an official profession. by act of bar association independence, this profession declared independent. many lawyers after islamic revolution have been filtrated and by th...

the effect of oleic acid (5 and 10% v/v) and xanthan gum (0.5 and 1% wt) on  partitioning and retention of ethyl acetate and diacetyl from two matrices with a different composition was investigated by applying static head space gas chromatography. two matrices with different composition have been developed: one containing carbohydrates (xanthan gum) and in the second one, called complex matrix,...

The benefits from practice follow a nonlinear function: Improvement is rapid at first but decreases as the practitioner becomes more skilled (see, e.g., Thorndike, 1913). The idea that a simple nonlinear function might describe practice effects in a broad range of tasks was championed by Newell and Rosenbloom’s (1981) influential chapter entitled “Mechanisms of Skill Acquisition and the Law of ...

Dynamical systems in nature exhibit selfsimilar fractal fluctuations and the corresponding power spectra follow inverse power law form signifying long-range space-time correlations identified as self-organized criticality. The physics of selforganized criticality is not yet identified. The Gaussian probability distribution used widely for analysis and description of large data sets underestimat...

To be published in Phys. Rev. E (2005). We present a simple point process model of 1/f β noise, covering different values of the exponent β. The signal of the model consists of pulses or events. The interpulse, interevent, interarrival, recurrence or waiting times of the signal are described by the general Langevin equation with the multiplicative noise and stochastically diffuse in some interv...

In this paper hemodynamic wall parameters which play an important role to diagnose arterial disease were studied and compared for three different rheology models (Newtonian, Power law and Quemada). Also because of the pulsatile behavior of blood flow the results were obtained for three Womersley numbers which represent the frequencies of the applied pulses. Results show that Quemada model alway...

Till now, different constitutive models have been applied to model the hot deformation flow curves of different materials. In this research, the hot deformation flow stress of API X65 pipeline steel was modeled using the power law equation with strain dependent constants. The results was compared with the results of the other previously examined constitutive equations including the Arrhenius eq...

We present a simple point process model of 1/f(beta) noise, covering different values of the exponent beta . The signal of the model consists of pulses or events. The interpulse, interevent, interarrival, recurrence, or waiting times of the signal are described by the general Langevin equation with the multiplicative noise and stochastically diffuse in some interval resulting in a power-law dis...

A procedure for analysis of experimental data and model discrimination in regression of rate data of reversible, heterogeneous reactions which uses the power-law rate expression is described. The numerical values of the power-law parameters are calculated first by regression of the experimental data. These parameters are used to assess whether the quality of the experimental data is sufficient ...
