Modern software development approaches, especially the model-driven approaches, heavily rely on the use of models during the whole development process. With the increasingly integrated tools these models converge into one unified model for various artifacts from various development activities. These unified models evolve over extended periods of time, which creates an emerging demand for versio...

background and aims. the main purpose of this study was to assess intra- and inter-examiner reproducibility of probing depth measurements with a manual periodontal probe. materials and methods. in this study, 32 dental students in tabriz faculty of dentistry with normal periodontium were evaluated. each tooth of the upper right quadrants, except the third molars, was examined. probing depths we...

This paper models the trade-off between production and appropriation in the presence of simultaneous interand intra-group conflicts. The model exhibits a ‘group cohesion effect ’: if the contest between the groups becomes more decisive, or contractual incompleteness between groups becomes more serious, the players devote fewer resources to the intra-group conflict. Moreover, there is also a ‘re...

MESSENGERS is a paradigm for the programming of distributed systems. It is based on the principles of autonomous messages, called Messengers, which carry their own behavior in the form of a program. This enables them to navigate freely in the underlying computational network, communicate with one another, and invoke pre-compiled node-resident functions. Coordination is facilitated at two distin...

Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...
