Reduction of bridge positions along bridge disks

Vulnerability Reduction for Bridge Piers

A nuclear-envelope bridge positions nuclei and moves chromosomes.

Positioning the nucleus is essential for the formation of polarized cells, pronuclear migration, cell division, cell migration and the organization of specialized syncytia such as mammalian skeletal muscles. Proteins that are required for nuclear positioning also function during chromosome movement and pairing in meiosis. Defects in these processes lead to human diseases including laminopathies...

To bridge or not to bridge?

OBJECTIVE Ventricular assist devices (VAD) are an important therapy that saves the lives of candidates a waiting heart transplantation (HTx). However, there are questions about posttransplantation effects of VADs. METHODS Seventy-four patients with end-stage heart failure who underwent HTx in our clinic between February 2007 and July 2011 were divided into two groups; a bridge cohort (n = 28)...

Construction of Nagisa Bridge Hybrid System of Cable-stayed Pc Bridge and Steel Suspension Bridge

Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cabl...

laboratory investigation of performance of l-shaped collar on reduction of local scour around bridge abutment

scour around bridge piers is one of the most important fields of hydraulic research. local scour around bridge piers and abutment is one of the main reasons of bridge failures. in the field of scour at the bridges, researches are more focus on scour of piers in compare with abutment. while the available information on the bridge failures required cost, the major problems are related to abutment...
