the aim of this study is to review the rentier state theory, with special regard to iran. iran’s rentier state is highly dependent on oil revenues, but much less on tax revenues. even this negligible reliance on tax revenues, itself seems to be indebted to oil revenues. thus the main research hypothesis is that iran’s oil revenue is one of the main determinants of tax revenues. to empirically t...

linear state bisection is introduced as a new method to find time-invariant state feedback control laws for a special form of underactuated nonlinear systems. the specialty of the systems considered is that every unactuated state should be coupled with at least two directly actuated states. the basic idea is based on bisecting actuated states and using linear combinations with adjustable parame...

this article outlines the questionable role of non-state law that is based on globalization and rise of private law making. proponents of non-state law believe that there are numerous private legislators which make legal rules that govern large groups. the article examines troubled concept of non-state law and its shortcomings and benefits. it considers non-state law by theoretical and empirica...

the reaction mechanism between (h2c) and (7, 0), zigzag single-walled carbon nanotubes(zswcnts) on two different orientation of c-c have been studied by semi empirical am!method. the activation barriers of (h2c) adding to (7, 0) zswcnt are computed and compared.the effects of diameters of zigzag swcnt on their binding energies were studied
