(Springer Verlag, 2019-01-07)Context: The relationship between silvicultural management and the quality of timber produced is not entirely elucidated. Aims: The effects of thinning on structural grade-determining properties of wood (elastic modulus, ... -
The effect of wastewater treatment processes, in particular ultraviolet light treatment, on pathogenic virus removal: EPA Research Report 171
(Environmental Protection Agency, 2016-05)Format: pdf Download now Municipal wastewater treatment plant discharges are a recognised source of human pathogenic viruses. Of concern within this group is norovirus the leading cause of viral gastroenteritis ... -
Effect of welding on microstructure and mechanical response of X100Q bainitic steel through nanoindentation, tensile, cyclic plasticity and fatigue characterisation
(Elsevier, 2020-12-30)This paper presents an experimental characterisation of fatigue at welded connections for the next-generation high-strength low-alloy offshore riser steel, X100Q. An instrumented girth weld is conducted with a parallel ... -
The effects of array configuration on the hydro-environmental impacts of tidal turbines
(Elsevier, 2014-04)The economic viability of tidal turbines will require the deployment of multiple devices in array formations in a manner analogous to wind farms. This research investigates the effects of the configuration of a tidal turbine ... -
The effects of array configuration on the hydro-environmental impacts of tidal turbines.
(2012)Tidal stream turbines provide a technically viable means of generating electricity from a sustainable resource; however, economic viability will require the deployment of multiple devices in array formations in a manner ... -
Effects of complex hydrodynamic processes on the horizontal and vertical distribution of Tc-99 in the Irish Sea
(Elsevier ScienceDirect, 2010-10-14)The increased discharge of Tc-99 from the Sellafield plant following the commissioning of the Enhance Actinide Removal Plant in 1994 was reflected in higher Tc-99 activity concentrations over much of the Irish Sea The ... -
Effects of fertiliser on phosphorus pools in soils with contrasting organic matter content: A fractionation and path analysis study
(Elsevier, 2018-12-05)With the intensification of agricultural production in many European countries, more marginal soils with elevated organic matter (OM) content are being brought into cultivation. However, little is known about the transformations ... -
Effects of in vitro endochondral priming and pre-vascularisation of human MSC cellular aggregates in vivo
(2015)Introduction: During endochondral ossification, both the production of a cartilage template and the subsequent vascularisation of that template are essential precursors to bone tissue formation. Recent studies have found ... -
