As more and more information from autonomous databases becomes available to lay users, query processing over these databases must adapt to deal with the imprecise nature of user queries as well as incompleteness in the data due to missing attribute values (aka “null values”). In such scenarios, the query processor begins to acquire the role of a recommender system. Specifically, in addition to ...

statement of the problem: endodontic surgery if required is considered as an additive therapy after classic endodontic treatments. the most prevalent type of endodontic surgeries are apicoectomy and corrective surgeries. type of material applied in apicoectomies is of high importance. root end filling material should not only be biocompatible but also provide appropriate seal. considering these...

introduction: the aim of this study was to compare the formation of dentinal crack and craze lines in the root dentin during root canal preparation with three different niti endodontic systems, naming reciproc (rcp), protaper universal (ptu) and mtwo. methods and materials: one hundred extracted mandibular premolars with single canals were selected and decoronated. the teeth were randomly divid...

This project explores the development of a hard-ware/software infrastructure to enable the provision of quality of service (QoS) guarantees in high performance networks used to conngure clusters of worksta-tions/PCs. These networks of workstations (NOWs) have emerged as a viable high performance computational vehicle and are also being called upon to support access to multimedia datasets. Examp...

The Academic Information System (xSIA) is built to its users manage Study Program modules, including student academic grades. xSIA applying the Moodle Learning Management (LMS) was developed by implementing Quick UDP Internet Connection (QUIC) technology with HTTP/3 protocol which can demonstrate transaction speed performance. design of information systems and databases employs Convention Over ...

abstract : inflammatory external root resorption (ierr) is a pathological phenomenon of microbial origin. this stu dy reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (rct). radiographic investigation revealed periapical radiolucencies...

introduction: the purpose of this study was to evaluate and compare canal preparation pattern of k3 and protaper rotary files in curved resin blocks. materials and methods: twenty-four resin blocks were used in this experimental study and randomly divided into two groups. their initial images were scanned. after preparation, their images were scanned again in the same position. pre and post pre...
