This article aims to study lease and hiring contract in the Iranian-Islamic setting and analyze the asymmetric information problem in these contracts. For doing this, we study the characteristics of lease and hiring contracts in Iran (real world experimental characteristics that recognized in other studies), using library method, then we mathematically model different aspects of asymmetric info...

     In this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. Afterward, effects of time and heating on water uptake were investigated. The highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºC was about 2129% after 4 days at equilibrium state. Hydrogels exhibited p...

In this paper the flow field of a rectangular synthetic jet driven by a piezoelectric membrane issuing into a quiescent environment is studied. The similarities exhibited by synthetic and continuous turbulent jets lead to the hypothesis that a rectangular synthetic jet within a limited region downstream of the orifice be modeled using similarity analysis just as a continuous planar jet. Accordi...

Systematic, well-designed research provides the most effective approach to the solution of many problems facing highway administrators and engineers. Often, highway problems are of local interest and can best be studied by highway departments individually or in cooperation with their state universities and others. However, the accelerating growth of highway transportation develops increasingly ...

traded against two simple orders or another combination. Liquidity is enhanced by matching simple orders against combination orders whenever possible. As long as prices are available in one contract and in the combination market, liquidity is automatically transmitted to all contracts. Although SOFFEX has implemented a subset of these combination functions, the implications of this functionalit...

Background: ART contracts involving third parties have been created while clinical reproductive treatments are globally widespread. Iran is pioneer in applying these treatments in middle-east due to shii’at jurisprudence prescribing them. This key role in region, has raised Iranian jurists’ responsibility in developing a legal system regarding administration of ART. The most significant part of...
