Abstract Two‐ or more‐factor general equilibrium models commonly assume no factor intensity reversals (FIRs): a good that is relatively capital intensive compared with other goods within country/region also another country/region. This assumption so important its breakdown results in the collapse of several well‐known theorems, such as Heckscher–Ohlin theorem and Stolper–Samuelson theorem. Seei...

Introduction: Radiotherapy is one of the effective methods in the treatment of cancer. In the recent methods of radiotherapy, intensity modulated radiotherapy (IMRT) technique by compensators is used. when photon beam passes the compensator, scattered photons can be generated within the compensator. The presence of scattered photons may complicate the design of compensators as...

based on, historical seismicity, position of 19-century instrumental epicenters, fault zones, relation of seismicity with active faults, and structural geology, statistics of earthquake activites, model studies for estimation of acceleration, and other information of intensities of iranian earthquakes, and for simplicity in the usage, the country is divided into two intensity provinces. in the ...
