The importance of pre-tensioning cable bolts used to reinforce of arch yielding support
E3S Web of Conferences, 2018 Widespread in Polish hard coal mining, cable bolts are used to reinforce the arch yielding support of roadways. This article attempts to prove that change in approach to long bolting technology can bring significant benefits in terms of improving the ...

Large‐scale tests of 50‐year‐old prestressed concrete bridge girders
Structural Concrete, EarlyView.Abstract An experimental investigation has been carried out as part of the BRIDGE|50 research project, focusing on large‐scale loading tests performed on five 50‐year‐old prestressed concrete (PC) girders. The study aimed at evaluating the structural response of five girders retrieved from a viaduct in the urban area of Turin, Italy, subjected to 4 ...

Journal of the Royal Anthropological Institute, EarlyView.This article analyses a new wealth tax (the IGF) in Bolivia against the backdrop of the 2019 ousting of former president Evo Morales. In doing so, it engages calls for ‘a return to politics’ in anthropology by proposing the notion of a ‘fiscal grievance politics’ as animating elite opposition to the tax in lowland Santa Cruz department. I show that the

A New Multiconstraint Method for Determining the Optimal Cable Stresses in Cable-Stayed Bridges
The Scientific World Journal, 2014 Cable-stayed bridges are one of the most popular types of long-span bridges. The structural behaviour of cable-stayed bridges is sensitive to the load distribution between the girder, pylons, and cables.

Journal of the Royal Anthropological Institute, EarlyView.While death remains a popular topic for anthropology, relatively few ethnographic accounts consider the modern bureaucratic processes accompanying it. One such process is public health autopsy, which scholars have largely taken for granted. Existing analysis has regarded it as a form of ‘cultural brokering’ and autopsy reluctance in communities is seen,
