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...

1. We compared the visuomotor processing underlying the onset and offset of pursuit by recording the eye movements of three monkeys as they smoothly tracked a target that was initially at rest, started to move suddenly at a constant velocity along the horizontal meridian, and then stopped. We presented this sequence of target motions in two different contexts. In the first context the target so...

1 Introduction This paper is concerned with the use of stock indices futures to hedge the return on portfolios. This topic has received considerable attention in the literature, which will be briefly summarised in section 2 of the paper. First of all it is desirable to consider the nature of hedging.

In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. The quality of reproduction of colour images in offset printing is dependent on a nu...

To solve the problem of generalized design and batch processing face gear, a method tooth surface side milling ruled line gears is proposed in this paper. First all, discrete points pitch cone gear are calculated, straight-line cluster section curve constructed to analyze deviation gear. Secondly, model constructed, curvature contact trace calculated. Thirdly, tangent analyzed, feed plane equid...
