In the late 1770s, humans achieved a milestone in bridge technology with the development of the Iron Bridge in Shropshire, England. Between the 18th and 19th centuries, thousands of bridges were built in the United States and Canada, drawing inspiration from earlier designs in Switzerland and Ger...

Engineers serve in various roles, from creating, improving and maintaining massive structures like highways and bridges to designing smaller items like laptops, smartphones and athletic sneakers.Aerospace engineersdesign and test technology used in spacecraft, aircraft and satellites whilebiomedical engineers...
The data of the damping ratios of structure were collected and analyzed. The limitations on the current researches on the bridge damping ratio were pointed out. In order to make up the limitation of the lack of data of the damping ratios of bridges,three bridges damping ratios were tested. ...

Civil engineering is a professional discipline that entails the design, construction, and maintenance of the natural world and man-made structures, such as bridges, dams, and sewage systems. Architectural engineering Construction management Ecological engineering ...
In recent years, it has been found that nearly 90 % of the major defects in concrete bridges have been traced to cracking caused by problems such as inadequate toughness or shrinkage of the material. This is because when the concrete on the bridge cracks to varying degrees, the reinforcement...
This hypothesis is given by the apparent increase in aggressive content in pornographic videos, especially the more subtle violence (Bridges et al., 2010; Carrotte et al., 2020) and how viewing of this pornographic material can favor the acquisition of these sexual scripts in offline sexual ...
