BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...

Abstract Interactional linguists are interested in ways which communicative resources emerge from interactional practice. This paper defines a place for the study of gesture within linguistics, conceived as ‘linguistics time’ ( Hopper, 2015 ). It shows how hand gestures certain kind – conceptual ‘hands-on’ instrumental actions, repeated and habitualized, taken to other contexts where they enabl...

abstract   background: different methods of surgical treatment for acromioclavicular(ac) joint injury were considered in the literature. the purpose of the study was to compare intra- articular ac repair technique with the extra-articular coracoclavicular repair technique for the patients with rockwood type iii and vac joint injury when indicated.   methods: nineteen consecutive patients with r...

contact mechanics is related to the deformation study of solids that meet each other at one or more points. the physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. contact mechanics gives essential information for the s...

the aim of the present paper is to sbo» that anti-realism in science, 1vhich has a1;guab/y become more fashionable in recentyears, contrary to tuha: its proponents assert, cannot make use of quantum mechanics and its impressiue achievements as a frump card in justifying its claims. i will argue that scientific anti-realism far from providing scientific communiry with a progressive methodologica...

BACKGROUND Pressure support ventilation (PSV) is a standard method for non-invasive home ventilation. A bench study was designed to compare the effectiveness of patient-ventilator inspiratory termination synchronization with automated and conventional triggering in various respiratory mechanics models. MATERIAL AND METHODS Two ventilators, the Respironics V60 and Curative Flexo ST 30, connected...
