the purpose of this article is to design a model for measuring productivity in the public sector . to this end both effectiveness and efficiency are considered. the measurement of effectiveness focus on four dimention ; service delivering to client, citizen satisfaction, improvement of society?s conditions and undesired outcomes of service delivery . we used delphi methods to define the effecti...

Abstract Computational modelling of a centrifugal technique for separating binary mixtures thermoplastic polymers in the molten state is presented. The may be useful recycling polymeric materials. study investigates physical process component separation due to force batch process, showing potential using dispersed model describing complex mechanism underlying technique. Given long time scales c...

background:the diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. in this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in iran. methods: we retrospectively review...

Since the mid-1980s, cesarean section rates in Canada have declined. By 1993, 18 of every 100 deliveries were by cesarean section, compared with close to 20 per 100 in 1987. As well, in 1993, 9 of every 100 deliveries were primary cesareans, down from a high of almost 11 per 100 in the mid-1980s. And the repeat cesarean section rate fell from 39 per 100 cesareans in the mid-1980s to 34 in 1993....

A low-order method is presented for aerodynamic prediction of wings operating at near-stall and post-stall flight conditions. The intended use in design, modeling, simulation. In this method, the flow separation due to stall modeled a vortex lattice framework as an effective reduction camber, or “decambering.” For each section wing, parabolic decambering flap, hinged location section, calculate...
