there is strong evidence demonstrating that nifedipine dissolved in ethanol selectively inhibits only l-type ca2+ current. in addition, acute ethanol exposure reduces voltage-dependent calcium currents. in the present study, we investigated the antagonistic effect of fixed concentration of nifedipine dissolved in different concentration of ethanol on l-type ca2+ current. in a na+-k+ free soluti...

The size of an organism reflects its metabolic rate, growth rate, mortality, and other important characteristics; therefore, the distribution of body size is a major determinant of ecosystem structure and function. Body-size distributions often are multimodal, with several peaks of abundant sizes, and previous studies suggest that this is the outcome of niche separation: species from distinct p...

The concept of change simply entails the totality of ways in which a particular entity has grown better and grown worse. Five studies suggest that this is not how people actually understand it for themselves. Rather, when asked to assess how they have "changed" over time, people bring to mind only how they have improved and neglect other trajectories (e.g., decline) that they have also experien...

Bosonisation of the massive Thirring model, with a non-minimal and non-abelian gauging is studied in 2+1-dimensions. The static abelian model is solved completely in the large fermion mass limit and the spectrum is obtained. The non-abelian model is solved for a restricted class of gauge fields. In both cases explicit expressions for bosonic currents corresponding to the fermion currents are gi...

The student movement is considered as one of the important issues of Iranian political sociology, but its role and its nature and its relationship with other movements and movements in Iran have been discussed. The present article is trying to answer the role and function of the student movement in Iran. Using a descriptive-analytic approach, political currents have become instrumental in most ...

It is proposed to use a single base platform in the Persian Gulf considering its low depth and more appropriate environmental conditions in comparison to North Sea and Mexico Gulf where this kind of platform is very popular. The pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. Using SACS 5.3 sof...

superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...

in this article, thanks to phenomenological approach, an attempt is made to account the correlation between globalization and neo-regionalism. in the process, the finding of this scholar convinced him to reject antithetical correlation between the two. instead, he argues neo-regionalism is and ecopolitical current to adjust globalization. in the final analysis, it is argued both currents are re...
