A quantitative microbial risk assessment model for total coliforms and e. coli in surface runoff following application of biosolids to grassland
(Elsevier, 2017-03-06)
In Ireland, the land application of biosolids is the preferred option of disposing of municipal sewage waste. Biosolids provide nutrients in the form of nitrogen, phosphorus, potassium and increases organic matter. It is ...
Impacts of zeolite, alum and polyaluminium chloride amendments mixed with agricultural wastes on soil column leachate, and CO2 and CH4 emissions.
(Elsevier, 2017-11-02)
This study aimed to quantify leaching losses of nitrogen (N), phosphorus (P) and carbon (C), as well as carbon dioxide (CO2) and methane (CH4) emissions from stored slurry and from packed soil columns surface applied with ...
Optimised analytical models of the dielectric properties of biological tissue
(Elsevier, 2017-02-09)
The interaction of electromagnetic fields with the human body is quantified by the dielectric properties of biological tissues. These properties are incorporated into complex numerical simulations using parametric models ...
Effect of logarithmic and linear frequency scales on parametric modelling of tissue dielectric data
(IOP Publishing, 2017-02-03)
The dielectric properties of biological tissues have been studied widely over the past half-century. These properties are used in a vast array of applications, from determining the safety of wireless telecommunication ...
Antimicrobial compounds (triclosan and triclocarban) in sewage sludges, and their presence in runoff following land application
(Elsevier, 2017-04-28)
The reuse of treated municipal sewage ( biosolids ) on land is an effective method to divert waste away from landfill and to use an alternative, low cost method of fertilisation. While legislation has mainly focused on the ...
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 ...
Development of a Global Energy Management System for non-energy intensive multi-site industrial organisations: A methodology
(Elsevier, 2017-01-25)
For multi-site organisations, informed decision making on capital investment aimed at improving energy performance and cutting carbon emissions, across a global site base, is a complex problem. This work presents the ...
One way of representing the size and shape of biomass particles in combustion modeling
(Elsevier, 2017-06-29)
This study aims to provide a geometrical description of biomass particles that can be used in combustion models. The particle size of wood and herbaceous biomass was compared using light microscope, 2D dynamic imaging, ...
Influence of soil phosphorus status, texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses
(Wiley, 2017-12-13)
Cost effective strategies for using chemically amended organic fertilizers need to be developed to minimize nutrient losses in surface and groundwater. Coupling specific soil physical and chemical characteristics with ...
Secondary comminution of wood pellets in power plant and laboratory-scale mills
(Elsevier, 2017-03-14)
This study aims to determine the influence of mill type and pellet wood composition on particle size and shape of milled wood. The size and shape characteristics of pellets comminuted using power plant roller mills were ...
