Comparison of high temperature chars of wheat straw and rice husk with respect to chemistry, morphology and reactivity
(Elsevier, 2016-03-02)
Fast pyrolysis of wheat straw and rice husk was carried out in an entrained flow reactor at high-temperatures (1000–1500) °C. The collected char was analyzed using X-ray diffractometry, N2-adsorption, scanning electron ...
Microplastics in sewage sludge: effects of treatment
(American Chemical Society, 2016-12-12)
Waste Water Treatment Plants (WWTPs) are receptors for the cumulative loading of microplastics (MPs) derived from industry, landfill, domestic waste water and storm water. The partitioning of MPs through the settlement ...
A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation
(De Gruyter Open, 2016-12-30)
During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures, is challenging. This study establishes a methodological framework to identify appropriate experimental ...
Infrared thermography technique as an in-situ method of assessing heat loss through thermal bridging
(Elsevier, 2016-11-17)
A key aspect in assessing the thermal standard of building envelopes is the quantification of the heat loss though thermal bridging, which can be expressed in terms of the linear thermal transmittance Psi. Values of W may ...
Smartphones, biometrics, and a brave new world
(Institute of Electrical and Electronics Engineers (IEEE), 2016-09-09)
In this article, we take a somewhat contrarian viewpoint - that biometrics may, in fact, offer solutions to many of today's cyber-security problems that appear with increasing frequency in prime-time news. This outcome ...
Lifecycle environmental and economic performance of nearly zero energy buildings (NZEB) in Ireland
(Elsevier, 2016-01-16)
Directives in the European Union are ensuring that buildings in this region are moving towards nearly zero energy buildings (NZEB). For countries like Ireland, which has a temperate oceanic climate, a key to achieving NZEB ...
Real-time monitoring to investigate structural performance of hybrid precast concrete educational buildings
(Taylor & Francis, 2016-11-22)
The motivation and implementation of a real-time structural health monitoring strategy to determine the structural performance of a number of educational buildings recently constructed in Ireland is discussed in this paper. ...
Hydrogen sulfide oxidation in novel Horizontal-Flow Biofilm Reactors dominated by an Acidithiobacillus and a Thiobacillus species
(Taylor & Francis, 2016-03-17)
Hydrogen Sulfide (H2S) is an odourous, highly toxic gas commonly encountered in various commercial and municipal sectors. Three novel, laboratory-scale, Horizontal-Flow Biofilm Reactors (HFBRs) were tested for the removal ...
Greenways as a tourism resource: a study of user spending and value
(Taylor & Francis, 2016-01-18)
Cycling is increasingly recognized as a key tool in improving transport sustainability, promoting increased physical activity and improved public health and developing the tourism sector. While the provision of safe and ...
Using mental mapping to unpack perceived cycling risk
(Elsevier, 2016-01-04)
Cycling is the most energy-efficient mode of transport and can bring extensive environmental, social and economic benefits. Research has highlighted negative perceptions of safety as a major barrier to the growth of cycling. ...
