Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)
The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ...
Modelling of fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-03-04)
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 ...
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
(Elsevier, 2017-01-06)
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 ...
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 ...
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 ...
Statistical grain size effects in fretting crack initiation
(Elsevier, 2016-09-20)
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 ...
Dynamics and function of intracellular carbohydrate in activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)
Recovery of biodegradable plastics from activated sludge is a promising sustainable
technology. In this study, polyhydroxybutyrate (PHB) ¿ a biodegradable plastics
material - was produced by activated sludge performing ...
Production of polyhydroxybutyrate by activated sludge performing enhanced biological phosphorus removal
(Elsevier, 2010)
In this study, polyhydroxybutyrate (PHB) 'a biodegradable plastics material' was produced by activated sludge performing enhanced biological phosphorus removal (EBPR) in batch experiments under anaerobic, aerobic and ...
An analytical approach for the prediction of single pile and pile group behaviour in clay
(Elsevier, 2016-02-21)
In this paper, the 't-z method' is employed to describe the nonlinear behaviour of a single pile and is used to obtain simplified predictions of pile group behaviour by considering the interaction between two-piles in ...
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 ...
