thorough knowledge of the morphology and internal anatomy of the root canal system is essential, because it determines the successful outcome of endodontic treatment. the main goal of endodontic treatment is to prevent apical periodontitis and/or to promote the healing of periapical lesion. presence of two canals or roots on the palatal side of the first maxillary molar has rarely been reported...

The main question addressed in the present work is how to find effectively a recursive function separating two sets drawn arbitrarily from a given collection of disjoint sets. In particular, it is investigated in which cases it is possible to satisfy the following additional constraints: confidence where the learner converges on all data-sequences; conservativeness where the learner abandons on...

Java supports distributed programming using threads and Remote Method Invocation (JRMI). However, a Java thread does not match well with the object concept, and JRMI cannot easily used to synchronize distributed objects. This work proposes a more object oriented model for concurrent and distributed programming using the notion of separate objects. Separate objects are asynchronous objects maybe...

Explicitly or implicitly, feminist or not, much of the literature employing a political economy perspective has assumed the existence of two largely separate spheres: a public sphere located in the formal economy and dominated by men, and a private sphere confined to the household and managed by women. For non-feminist theorists, this assumption is evident in the focus on the formal economy to ...

This paper presents the outline of a module system for the Scheme programming language in order to solve several problems commonly encountered with contemporary implementations. These problems include the lack of support for separate compilation and crossmodule type checking as well as the necessity for non-standard language extensions to aid certain compiler optimizations like open compilation...

In this paper a rule learning algorithm for the prediction of numerical target variables is presented. It is based on the separate-and-conquer strategy and the classification phase is done by a decision list. A new splitpoint generation method is introduced for the efficient handling of numerical attributes. It is shown that the algorithm performs comparable to other regression algorithms where...

The provision of pure enantiomers is of increasing importance not only for the pharmaceutical industry but also for agrochemistry and biotechnology. In general, there are two rival approaches to provide pure enantiomers. The "chiral" approach is based on developing an asymmetric synthesis of just one of the enantiomers, while the "racemic" approach is based on separating mixtures of the two ena...
