in the urban history of iran, “mashroote” era (the constitutional revolution) is considered as a turning point. in this period, the government had an organized and purposeful interference in the urban development of the country. another organized interference of the government, happened in 1960s. the effects of these movements were very significant in the growth of urban patterns and in the urb...

in order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. these points are obtained by means of the solution of the two-dimensional navier-stokes equations via the standard arakawa-c finite-difference method. results show that in the marginal richardson numbers, the critical...

conclusions glenohumeral joint reduction with reconstruction of the humeral head seems to be possible even in a neglected locked posterior shoulder fracture-dislocation. if the depressed osteochondral fragment is still spheric, signs of the avascular necrosis are absent on ct, and mal:union: of the fragment has occurred, it is quite possible to reconstruct the head. although results of the case...

An Extremely rare case of periscaphoid and perilunate dislocation of the wrist is reported. The reported case is a young man with trauma following a motor cycle falling down. At first referral closed reduction and six weeks of long arm cast had been performed. The patient reffered to our hospital because of painful and limited range of motion. He underwent open reduction and internal fixatio...

one of the problems that sometimes occur in gas allocation optimization is instability phenomenon. this phenomenon reduces the oil production and damages downhole and surface facilities. different works have studied the stability and suggested some solutions to override it, but most of them (such as making the well intelligent) are very expensive and thus they are not applicable to many cases. ...

purpose: current study aimed to predict marital instability based on identity styles and emotion regulation skills among married women in qouchan. methodology: 331 female teachers were selected using single-stage cluster random sampling and were asked to answer the identity style questionnaires (isi-6g), emotion regulation skill questionnaires (ersq) and marital instability index (mii). data we...

introduction prediction of thunderstorm is one of the most difficult issues in weather forecasting. deep convective clouds develop at small spatial and temporal dimensions about 1-10 km and 1-12 h. various thermodynamic parameters have been discovered over the past 40 years, according to data obtained by radiosounds. the capability of these indices in forecasting instability varies over time an...

sufficient conditions are established under which the zero solution x = 0 of equation (2) isunstable.
