It seems that greater research activity on heat and mass transfer with circular impinging jets has been predominantly published [1 3, 15, 16].
For this reasons, a great deal of research activity has recently been focused on the development of advanced Virtual Reality-based visualization techniques capable of representing the energy flow through the machine tools in a clear and intuitive manner.
In recent years, storage of thermal energy has become a very important topic in many engineering applications and has been the subject of a great deal of research activity.
Highly anisotropic 2D nanosheets of inorganic solids with nanometer-level thickness attract a great deal of research activity because of their unique merits in exploring novel high performance photocatalysts applicable for environmental purification and production of renewable clean energy.
Although control engineering is now a mature discipline, it remains an area in which there is a great deal of research activity, and as new developments in both theory and applications become available, they will be included in the online version of the encyclopedia.
We have the opportunity with a new programme to trial new, tailored and culturally appropriate approaches to these groups, and there is currently a great deal of research activity and innovation in this area.
Since the original MVH valuation study was published by Dolan [ 2] in 1997, a great deal of research activity has taken place aimed at extending the global reach of the EQ-5D instrument by local implementation, validation and valuation of the EQ-5D instrument.
The second priority area, 'risk factors and causes', has some parallels with the greatest area of research activity in the UK (cancer biology).
With their direct access to patients, their comparatively large numbers of personnel, and their greater financial resources and research activity, organ-based specialties have tremendous advantages over IR in the competition for patients [ 18].
