Problems with Railway Track Drainage in Finland
(13.07.2016)
articleSeveral studies have shown that water plays a significant role in phenomena that weaken track geometry. For instance, water may cause frost heave, thaw softening, attrition of ballast, and weakening of the load bearing ... -
Shear bands in soft clays: strain-softening behavior in finite element method
(2015)
articleStrain-softening behavior of soft sensitive clays is very often neglected in <br/>geotechnical design. During undrained loading, such materials show a dramatic loss of strength after the peak stress, until ... -
Simultaneous biomass concentration and subsequent quantitation of multiple infectious disease agents and antimicrobial resistance genes from community wastewater
(09 / 2024)
articleWastewater-based surveillance (WBS) of infectious disease agents is increasingly seen as a reliable source of population health data. To date, wastewater-based surveillance efforts have largely focused on individual ... -
Soil plugging in small diameter tube samplers in silty soils
