Performance of Weld-Retrofit Beam-to-Column Shear Tab Connections

Dimitrios Lignos

Single plate shear tab connections are a simple means to connect beams to their supporting members. The tab is fillet-welded to the supporting column in the fabrication shop, and then field bolted to the beam web on the construction site. Sit-uations may a ...

Performance of a Reinforced Concrete Box Culvert Installed in Trapezoidal Trenches

Liang Sun, Baoguo Chen

The performance of embankment installation (EI) and trench installation (TI) culverts has been investigated through experimental, numerical, and analytical methods. However, there are few studies on the performance of trapezoidal TI (TTI) culverts. Therefo ...

SSI on the Dynamic Behaviour of a Historical Masonry Building: Experimental versus Numerical Results

Angelo Garofano

A reliable procedure to identify the dynamic behaviour of existing masonry buildings is described in the paper, referring to a representative case study: a historical masonry palace located in Benevento (Italy). Since the building has been equipped with a ...

Snow cover manipulation effects on microbial community structure and soil chemistry in a mountain bog

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

Alterations in snow cover driven by climate change may impact ecosystem functioning, including biogeochemistry and soil (microbial) processes. We elucidated the effects of snow cover manipulation (SCM) on above-and belowground processes in a temperate peat ...

Light Availability Prevails Over Soil Fertility and Structure in the Performance of Asian Knotweeds on Riverbanks: New Management Perspectives

Thomas Spiegelberger

Asian knotweeds (Fallopia spp.) are considered one of the world's most invasive species. Restoring habitats dominated by these exotic species requires a better understanding of the importance of abiotic factors controlling the invasive knotweeds performanc ...

Modelling soil carbon and nitrogen cycles during land use change. A review

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

Forested soils are being increasingly transformed to agricultural fields in response to growing demands for food crop. This modification of the land use is known to result in deterioration of soil properties, in particular its fertility. To reduce the impa ...

DNA extraction from soil samples: Time for high throughput efficacy

Pierre Rossi, Luiz Felippe De Alencastro, Claire Meugnier

Total DNA extraction is the key stage allowing the implementation of various downstream applications in molecular ecology. The widespread application of downstream technologies has led to an increasing demand for highly pure biomolecules. Manual methods an ...
