Background and Aims: Freestanding fixed partial prosthesis is considered the first choice whenever possible. However, anatomical limitations for implants and other reasons may create situation in which it would be preferable to connect the implants to teeth. A biomechanical dilemma in a tooth/implant-supported system comes from dissimilar mobility. This disparity cause the bridge to function as...
A Little while ago Mrs. A., a housewife in ^rpington, went on a bus. Though it sounds the east remarkable thing in the world, it was a tr'Umph in its way?because Mrs. A. had for Months had a fear of leaving her own house, which dipped her with a panic hand if she as much as stepped across the threshold. Marooned in her semi-detached just as irrevocably, it seemed, as a castaway, Mrs. A. had rea...
Purpose of research . This article analyzes thermal imaging surveys residential premises in monolithic houses built 2018 and 2019 the city Voronezh. Based on regulatory requirements Federal Law No. 261-F3 "On Energy Saving energy Efficiency improvement", question is raised about essential shortcomings structural units overlap associated with errors design installation. Such lead to formation pl...
Germ cells in most animals are connected by intercellular bridges, actin-based rings that form stable cytoplasmic connections between cells promoting communication and coordination [1]. Moreover, these connections are required for fertility [1, 2]. Intercellular bridges are proposed to arise from stabilization of the cytokinetic ring during incomplete cytokinesis [1]. Paradoxically, proteins th...
BACKGROUND Myocardial bridges represent a hotly debated research topic. Myocardial bridges are considered to be a vascular heart variation due to its intermittent or enduring reducing of the arterial lumen, with a possible ischemic effect. METHODS 154 hearts were studied, having been extracted as fresh autopsy material. Coronary arteries were injected with synthetic resin and cleaned by extra...
Background and Aim: All ceramic, inlay-retained resin bonded fixed partial denture is a conservative method for replacement of missing teeth, because of minimal tooth reduction. The connector between the retainer and the pontic is the weak point of these bridges. Reinforcement of ceramic core will increase the clinical longevity. The aim of this study was to determine the effect of zirconia on ...
Web of plate girders in bridges are usually reinforced by welded transverse stiffeners inorder to improve their shear capacity. Due to problems associated with field welding and fatigue,welded stiffeners are not suitable for retrofitting existing bridges. Bolted stiffeners are a practicalalternative for strengthening girders that are expected to experience shear stresses in excess of theirdesig...
