BACKGROUND AND AIM: It is required in many young patients that permanent first molars (PFMs) be extracted due to poor prognosis. This study investigates whether the extraction of such teeth is effective on the development of third molars and even their crown and root morphologies.METHODS: A total of 7000 panoramic radiographs were evaluated and 128 radiographs showing a history of extraction of...

abstract glaucoma management in pregnant patients is a real challenge, especially when the glaucoma is not controlled with medications. we report the results of 6 incisional glaucoma surgeries for the management of medically uncontrolled glaucoma patients during pregnancy. this retrospective, case series was conducted on the 6 eyes of 3pregnant patients with uncontrolled glaucoma using maximum ...

This paper details the way case-based reasoning has been used to aid footwear designers in creating new designs while maximizing component reuse. A hybrid system was created which uses an objectoriented memory model, neural networks for retrieval and fuzzy feature vectors to augment the basic case-based reasoning model. One of the main tasks involved in the design of any case-based system is de...

Two-Thickness-Method (TTM) based on an open-ended coaxial probe was investigated with an emphasis on uncertainty analysis to perfect this technique. Uncertainty equations in differential forms are established for the simultaneous measurement of complex electromagnetic (EM) parameters in the systematical consideration of various error factors in measurement. Worst-case differential uncertainty e...

introduction: in the absence of microvascular replantation or in crash injury cases in which obtaining an acceptable function is not possible, amputation of the injured finger seems to be the best treatment modality. some studies recommended leech therapy for this kind of injury after vascular repair to decrease venous congestion. case presentation: in this case report, the authors presented a ...

Testability has many effects on software. In general, increasing testability makes detecting faults easier. However, increasing testability of third party software components is difficult because the source is usually not available. This paper introduces a method to increase component testability. This method helps a user test when the component is reused during integration. First, we analyze a...

Contract signing is a fundamental service in doing business. The Internet has facilitated the electronic commerce, and it is necessary to find appropriate mechanisms for contract signing in the digital world. A number of two-party contract signing protocols have been proposed with various features. Nevertheless, in some applications, a contract may need to be signed by multiple parties. Less re...
