A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
(Elsevier, 2019-07-02)
Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ...
Effect of microwave and thermal co-pyrolysis of low-rank coal and pine wood on product distributions and char structure
(American Chemical Society, 2019-07-07)
Direct conversion of a low-rank coal into valuable chemicals or improving its char’s coking value became very demanding goals in coal utilization strategies. In this work, the co-pyrolysis of a low-rank lignite coal and ...
The effect of thinning on mechanical properties of Douglas fir, Norway spruce, and Sitka spruce
(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, ...
Deep neural network and data augmentation methodology for off-axis iris segmentation in wearable headsets
(Elsevier, 2019-08-01)
A data augmentation methodology is presented and applied to generate a large dataset of off-axis iris regions and train a low-complexity deep neural network. Although of low complexity the resulting network achieves a high ...
An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
(Departamento de Ingeniería en Maderas de la Universidad del Bio-Bio en Concepción, Chile, 2019)
The use of fast-grown timber in the manufacture of engineered wood products is increasing;
however, the fast growth rate results in a low-density timber that is susceptible to significant swelling
and shrinkage deformations ...
A bioresorbable biomaterial carrier and passive stabilization device to improve heart function post-myocardial infarction
(Elsevier, 2019-05-15)
The limited regenerative capacity of the heart after a myocardial infarct results in remodeling processes that can progress to congestive heart failure (CHF). Several strategies including mechanical stabilization of the ...
An integrated assessment of nitrogen source, transformation and fate within an intensive dairy system to inform management change.
(Public Library of Science, 2019-07-23)
From an environmental perspective optimised dairy systems, which follow current regulations, still have low nitrogen (N) use efficiency, high N surplus (kg N ha-1) and enable ad-hoc delivery of direct and indirect reactive ...
Characterization of woodstove briquettes from torrefied biomass and coal
(Elsevier, 2019-01-18)
Using waste biomass materials offers the potential to reduce the greenhouse gas emissions from fossil fuels. Torrefaction is very useful for improving the fuel properties of biomass in order to better match those of coal. ...
Evidence of stabilised peat as a net carbon sink
(American Society of Civil Engineers, 2019-01-09)
Mass stabilization, a ground improvement solution used for construction in peatlands, involves mixing suitable dry binders into the peat, increasing strength and stiffness and reducing permeability. A previous pilot study ...
Timber grading potential of Douglas fir in the Republic of Ireland and the UK
(Taylor & Francis, 2019-05-19)
Results of the recently approved machine control grading settings for Douglas fir in the Republic of Ireland and the UK have shown that the species can be graded to C18, and higher strength classes, and while there is a ...
