Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. the aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using mta or cem cement in diabetic rats. thirty two wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...

in this paper, evaluation of torsional stiffness in beam and slab bridge deck elements is presented. a beam and slab bridge decks structurally behave as a grillage. a grillage has an efficient transverse load distribution due to transverse asymmetric load. in the case of bridge deck without transverse beams in the span, transverse load distribution depends on the torsional stiffness of longitud...

Recent experimental research has shown that ordinary unbounded steel reinforced elastomeric bearings (SREBs) can be considered as an attractive cost-effective option for the seismic isolation of highway bridges. To further investigate its benefits, the current study is focused on the seismic risk assessment of an optimally designed highway bridge isolated by SREB system. A typical three-span hi...

Background: Distal tibia fractures are among the most common bony injuries, with a significant rate of nonunion anddelayed union. There are multiple methods for the management of distal tibia fractures. Among the plating methods,there are bridge plating and compression plating techniques. There is still a lack of evidence about whether one methodhas a higher rate of union than...

Middle-aged men bridge younger and older generations are burdened with social roles responsibilities that increase their risk of poor health. The aim this study was to investigate whether family stress had a mediating effect on the relationship between self-efficacy midlife crisis in sample 198 middle-aged South Korean men. Mediation analysis performed according Baron Kenny method using Sobel t...

We introduce a new class of edge labelings for locally finite lattices which we call SB-labelings. We prove for finite lattices which admit an SB-labeling that each open interval has the homotopy type of a ball or of a sphere of some dimension. Natural examples include the weak order, the Tamari lattice, and the finite distributive lattices.

Performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (VCE) could be considered as one of the main causes of bridges collapse. In most of bridge design codes, for seismic analysis of bridges, VCE is not taken into account or a distinguished method isn’t presented for assessment of VCE. In the present work, the effect of VCE on two existing...
