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 ...
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. ...
Microstructure modeling of high-temperature microcrack initiation and evolution in a welded 9Cr martensitic steel
(SAGE Publications, 2019-02-28)
Welded joints in tempered 9Cr-1Mo operating at elevated temperatures are well known to be prone to premature failure due to cracking in the heat-affected zone. This paper describes a crystal plasticity model to predict the ...
Categorization of tars from fast pyrolysis of pure lignocellulosic compounds at high temperature
(Elsevier, 2019-04-11)
This study presents how the yields of different tar compounds from pure lignocellulosic compounds respond to the change in temperature and residence time. Experiments were carried out with a drop tube furnace in the ...
A comparison of two quasi-static computational models for assessment of intra-myocardial injection as a therapeutic strategy for heart failure
(Wiley, 2019-05-06)
Myocardial infarction, or heart attack, is the leading cause of mortality globally. Although the treatment of myocardial infarct has improved significantly, scar tissue that persists can often lead to increased stress and ...
A study into the reasons for process improvement project failures: results from a pilot survey
(Emerald, 2019-07-22)
Purpose
Process improvement initiatives, such as Lean, Six Sigma and Lean Six Sigma, typically have common characteristics that are carried through projects. Whilst a project’s performance is an important determinant of ...
An exploratory study into the use of Lean Six Sigma to reduce medication errors in the Norwegian public healthcare context
(Emerald, 2019-09-26)
Purpose: Medication errors are a significant cause of injury in Norwegian hospitals. The purpose of this study is to explore how Lean Six Sigma has been utilised in the Norwegian public healthcare context to reduce ...
Manufacturing SMEs doing it for themselves: developing, testing and piloting an online sustainability and eco-innovation toolkit for SMEs
(Taylor & Francis, 2019-11-07)
Public discourse frequently cites the damaging activities of large organisations on global environmental issues, but smaller organisations are rarely, if ever, featured. Small and Medium Enterprises (SMEs) make up 99% of ...
A CFD investigation of a variable-pitch vertical axis hydrokinetic turbine with incorporated flow acceleration
(Springer, 2019-02-18)
This paper presents the numerical modelling of a novel vertical axis tidal turbine that incorporates localised flow acceleration and variable-pitch blades. The focus is to develop a computational fluid dynamics model of a ...
High-resolution measurements of leakage flow inside the hinge of a large-scale bileaflet mechanical heart valve hinge model
(Springer, 2019-06-24)
Purpose It is believed that non-physiological leakage flow through hinge gaps during diastole contributes to thrombus formation in Bileaflet Mechanical Heart Valves (BMHVs). Because of the small scale and difficulty of ...
