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 ...
Assessing capital investment on energy improvement projects from a global energy management perspective: a tri-generation case study
(NUI Galway, 2016)
For multi-national companies, assessment of energy improvement projects across a global site-base requires a thorough understanding of the driving factors affecting energy consumption on each site. Traditionally, assessment ...
Development of a global energy management system for the life sciences industry: an energy management maturity model implementation
(NUI Galway, 2015-11)
The Global Energy Management System (GEMS) research project proposes a novel methodology for assessing capital energy-efficiency projects at a global level. The paper scope covers the systematic development and implementation ...
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 ...
Methodology for quality checks for energy efficient buildings
(NUI Galway, 2017-03-01)
The built environment accounts for more than 40% of the overall energy consumption and 36% of the overall CO2 emissions in Europe. Moreover, statistics show that construction and the upkeep of European buildings and ...
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 ...
