Particulate phosphorus and suspended solids losses from small agricultural catchments: links to stream and catchment characteristics.
(2019)
Excessive phosphorus (P) inputs from agriculture are well established as a contributor to freshwater
eutrophication. Decreasing these inputs is an important step in improving the ecological state of impaired
waters. ...
Properties of Alkali Activated Materials made with bauxite refining residue (red mud-RM) and blends of RM with fly ash (FA)
(ISBN: 978-989-54499-3-4, 2023)
A bauxite refining residue (RM), both alone and blended with FA at 30% and 50%, is activated with alkalis (Na2SiO3 and Na2SiO3/NaOH)
to produce geopolymer cements. Alkali-activated materials (AAMs)/geopolymers are a more ...
Aeroacoustic source characterization technique applied to a cylindrical Helmholtz resonator
(2011)
The aim of this work is to investigate the sound produced by a Helmholtz resonator excited
by a boundary layer. A deep cylindrical cavity with a small rectangular opening was designed
to allow Helmholtz resonance as well ...
Tuned mass-damper-inerter (TMDI) for suppressing edgewise vibrations of wind turbine blades
(2020)
This paper proposes the use of a tuned mass-damper-inerter (TMDI) for the mitigation of edgewise blade vibrations in wind turbines. The hollow nature of the wind turbine blades is utilized to install a TMDI at a location ...
A Comparison of Coherence Based Acoustic Source Identification Techniques
(2005)
Four techniques of source identification are examined and the performance of each
evaluated with experimental data. The procedures are all frequency domain methods
and depend to some extent on the coherence function. The ...
The impact of labour market disruptions and transport choice on the environment during Covid-19
(2021)
Since late 2019, COVID-19 has devastated the global economy, with indirect implications for the environment. As governments’ prioritized health and implemented measures such as the closure of non-essential businesses and ...
Foundation damping for offshore wind turbines on monopile supports: a review
(2021)
Today, an important challenge for offshore wind energy is to design efficient and reliable offshore wind turbines (OWTs). The overall damping of OWTs plays an important role in the design process as it limits the amplitude ...
