Empirical correlations for the compression index of Irish soft soils
(ICE Institution of Civil Engineers, 2014-09-08)
Numerous correlations have been developed in the literature relating the compression index Cc of soft soils to simple index properties that serve as a useful reality check on oedometer test results. However, many of these ...
Nitrogen-limitation-induced carbon and phosphorus fluxes in anaerobic/aerobic sequencing batch reactors
Enhanced biological phosphorus removal (EBPR) has been applied widely in wastewater treatment plants. However, deterioration or failure of EBPR often happens because: (i) of the dominance of glycogen-accumulating organisms ...
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its ...
Treatment of landfill leachate in municipal wastewater treatment plants and impacts on effluent ammonium concentrations.
Landfill leachate is the result of water percolating through waste deposits that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements have ...
Statistical grain size effects in fretting crack initiation
A crystal plasticity computational framework is developed and validated to investigate the microstructure sensitivity of crack initiation in fretting. Randomly distributed microstructure geometries are incorporated into a ...
Use of zeolite with alum and polyaluminum chloride amendments to mitigate runoff losses of phosphorus, nitrogen, and suspended solids from agricultural wastes applied to grassed soils
(Crop Science Society of America, 2015-09-16)
Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products (DBP), which are potentially harmful to human health. This study ...
Modelling of fretting in the pressure armour layer of flexible marine risers
This paper presents a computational methodology for frictional contact mechanics of the pressure armour layer in flexible risers. This will allow, for the first time, quantification of key fretting variables, such as contact ...
Stone column effectiveness in soils with creep: a numerical study
(Taylor & Francis, 2016-03-16)
While it is well established that vibro stone columns reduce primary settlement and improve bearing capacity, their effect on creep compression has largely been overlooked to date. However, with increasing pressure to ...
Ground heave induced by installing stone columns in clay soils
(ICE Publishing, 2013-12)
Measurements of ground heave induced by installing stone columns in soft clay are presented in this paper. These measurements are likely to provide guidance to practitioners concerned about the possible impact of column ...
Discussion: Interaction factor for large pile groups
(ICE Publishing, 2016-09-27)
The authors present an interesting paper on the use of the interaction factor method (IFM) for settlement analysis of large pile groups.
