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...

AIM Placement of self-expandable metallic stent has been used for bridge to surgery in the treatment of colorectal obstruction. Our aim was to compare technical success and complication rates of covered and uncovered inserted stents in colorectal malignant obstruction patients. MATERIAL OF STUDY A series of 24 obstruction colorectal cancer patients were selected and included in the study for ...

Bridge rails are a type of longitudinal barrier that serves the important purpose of keeping vehicles on the bridge structure. Many different designs have evolved for bridge rails, including some based upon the cross sections used for rigid concrete safety shapes. These designs need to conform to the crashworthiness requirements of NCHRP Report 350 or MASH to be acceptable for use on U.S. highw...

The objective of this study was to determine the number of Eurasian otters (Lutra lutra) that occupied the Sincheon River in Daegu, South Korea. Twenty-seven spraints collected from February to May 2016 at four sites (Jangam Bridge approximately 6.1 km from the Gachang Dam, Docheong Bridge approximately 13.5 km, Chimsan Bridge approximately 15.1 km and Nogoek Bridge approximately 18 km) along 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.
