Lightning is an extremely energetic electric discharge process in our atmosphere. It significantly affects the concentration of greenhouse gases and it threatens electrical and electronic devices, in particular, when placed on elevated structures like wind turbines or aircraft, and when these structures are built with modern composite materials with inherently low electric conductivity. In addition, even our fundamental understanding of atmospheric electricity is far from complete. New discharge processes in the atmosphere above thunderstorms have been discovered, the so-called Transient Luminous Events (TLEs) in the stratosphere and mesosphere, and Terrestrial Gamma-ray Flashes (TGFs) that emit particle beams of antimatter. These phenomena demand thorough investigations, in geophysics and in the related fields of plasma and high-voltage technology where similar discharges appear. These challenges are approached within the SAINT project with a multidisciplinary and inter-sectorial training platform for 15 ESRs. The platform brings together satellite and ground observations with modelling and lab experiments. It couples scientific studies to applications relevant to industries developing satellite data products, plasma discharge technologies, lightning detection systems and lightning protection devices. With SAINT, we take advantage of the extraordinary opportunity presented by three simultaneous space missions with dedicated instruments to study lightning discharges, TLEs and TGFs, to integrate the unique space data with dedicated novel ground observations, model developments and lab experiments. SAINT will train the next generation of young, innovative scientists to shape the future of research and technology in Europe.

The feijoa plant (Feijoa sellowiana, family Myrtaceae, synonym, Acca sellowiana) produces fruit similar to that of the guava. It is native to Brazil but is grown in many countries as a food crop, especially New Zealand, where it is valued for its highly aromatic fruit. This review covers published work on the bioactive components of the fruit of the feijoa and their pharmacology. Potential value might be added to this fruit if extracts of the fruit were to be used for nutraceutical purposes. © 2010 Elsevier Ltd. All rights reserved.

Lichtenecker's logarithmic mixture formula for dielectrics has proven to be a useful practical formulation for determining the effective permittivity of homogenized dielectric mixtures. However, the formula itself has long been regarded as semiempirical in nature without firm theoretical justification. This paper shows that Lichtenecker's formula can be derived by applying Maxwell's equations and the principle of charge conservation to a mixture for which the spatial distribution of shapes and orientations of the components is randomly distributed. Furthermore, the relationship between the Lichtenecker formula and the well-known mixture formulas due to Maxwell-Garnett is demonstrated. Similarly, it is shown that the symmetric mixture formula of Bruggeman can also be obtained from the Lichtenecker formula. © 2006 IEEE.

We study electron transport through a hybrid single-electron transistor, consisting of a superconducting island and normal-metal electrodes, in the Coulomb blockade regime. We derive analytic expressions for the elastic and inelastic cotunneling currents, which exhibit power law suppression induced by the dissipative electromagnetic environment. The results can be used to improve the accuracy of hybrid devices employed in electrical metrology and for noise measurements in quantum information processing. © 2011 American Physical Society.

The invention relates to the use of B2 angiogenic crystallin proteins to promote angiogenesis, wound healing and/or endothelial cell migration. B2 crystallin has particular application in these methods. The crystallins will usually be in monomeric form. Typically, truncated form(s) of B2 crystallin protein are utilized as can be prepared by partial hydrolysis of the protein by a protease enzyme such as elastase I. Methods for the purification of crystallin proteins from eye tissue are also described.

A process for the separation of carbon dioxide from gas mixtures is disclosed in which a metal oxide sorbent, which is used to capture and release carbon dioxide, is recycled. The process incorporates the regeneration of the carbon dioxide capture capacity of the metal oxide to maintain a high capture capacity over many cycles. The regeneration involves hydrating the metal oxide and then heating the resulting metal hydroxide under a gas atmosphere that is effective to suppress the dehydration of the hydroxide so that dehydration occurs at an elevated temperature. The regeneration may also be used independently from the carbon dioxide separation process to produce, from a metal hydroxide, a metal oxide having an enhanced resistance to attrition and fragmentation.

A hand-held mobile 3D scanner (10) for scanning a scene. The scanner (10) comprises a range sensor (11) that is arranged to sense the location of surface points in the scene relative to the scanner (10) and generate representative location information, a texture sensor (12) that is arranged to sense the texture of each surface point in the scan of the scene and generate representative texture information, and a position and orientation sensor (13) that is arranged to sense the position and orientation of the scanner (10) during the scan of the scene and generate representative position and orientation information. A control system (14) is also provided that is arranged to receive the information from each of the sensors and generate data representing the scan of the scene.
