corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (rc) structures deterioration in chloride-contaminated environments. as a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. the corrosion propagation phase is a ...

The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...

amitraz is a triazapentadiene, an α2 adrenergic agonist and a member of the amidine chemical family. a limited number of human intoxication cases have been published in the literature. lack of a clear and specific protocol for the therapy of amitraz intoxication may make its successfully managed case reports useful and valuable for other clinical practitioners in poisoning departments. the case...

developmental dysplasia of the hip (ddh) is the most frequent developmental disorder of the locomotor system. it is detected among 0.1–5.2% of newborns (1, 2). this might be the reason, that there is a high interest to detect ddh cases as early as possible. undetected or late cases lead to catastrophes for the patient and family. limping, leg length discrepancy, pain, frequent operations and so...

Familial studies in inflammatory polyarthritis indicate strong hereditary factors, particularly in relationship to the serological tests (Lawrence and Ball, 1958). In a single kindred of some 3,000 persons reported briefly by Whittinghill, Hendricks, Taylor, and Thorp (1958), rheumatoid arthritis was distributed independently of spondylitis and Still's disease. The ten spondylitics had higher t...

The Interpretive Visualization (IVIS) Group at the Division of Biomedical Communications, Dept. of Surgery, University of Toronto has developed a visually-oriented, Internet-based Continuing Professional Development (CPD) course on Sentinel Node Biopsy. The site design methodology involved an extensive needs assessment, iterative formative evaluations of site and media design, a summative evalu...

BACKGROUND Posts are used to enhance crown buildup in pulpless teeth with destructed crown portion. Different types of post are used in endodontically treated teeth. The aim of the present in vitro study was to evaluate fracture resistance of custom made, metal, glass fiber reinforced and carbon reinforced posts in endodontically treated teeth. MATERIALS AND METHODS An in vitro study was carr...

This study carried out comparative seismic performance of reinforced concrete frames infilled by masonry walls with different heights. Partial and fully infilled reinforced concrete frames were modeled for the research objectives and the analysis model for a bare reinforced concrete frame was also established for comparison. Non–linear static analyses for the studied frames were performed to in...

Scandium-reinforced aluminum alloys represent a new generation of high-performance alloys that display numerous advantages over high-strength aluminum alloys. Scandium-reinforced alloys are much stronger than other high-strength alloys, exhibit significant grain refinement, strengthen welds, and eliminate hot cracking in welds. These alloys also exhibit a good resistance to corrosion as shown b...

PURPOSE The aim of this study was to investigate the effect of reinforcing materials on the fracture resistances of glass fiber mesh- and Cr-Co metal mesh-reinforced maxillary complete dentures under fatigue loading. MATERIALS AND METHODS Glass fiber mesh- and Cr-Co mesh-reinforced maxillary complete dentures were fabricated using silicone molds and acrylic resin. A control group was prepared...
