Kurz vor Weihnachten ist noch einmal Neumond Emily und Elisa freuen sich auf ein weiteres Abenteuer mit dem jungen und frechen Einhorn. Dieses ist vollkommen erstaunt, dass die Zwillingsschwestern nicht an den Weihnachtsmann glauben Das kann Eddy nat rlich nicht auf sich beruhen lassen, und nimmt die Beiden kurzerhand mit an den Nordpol um den Kindern zu beweisen, dass es den Weihnachtsmann wirklich gibt...

When the focus is on diffusioninstead of propagation, from the modelingpointof view this corresponds to neglecting the time derivative of the electric induction (i.e., thedisplacement current introducedby Maxwell)or, alternatively,neglectingthe time derivative of the magnetic induction.

Eddy Kamuanga s large-scale figurative paintings display a wealth of historical understanding in a sophisticated interplay of strikingly coloured forms juxtaposed on grey negative space. Kamuanga s work taps into the rich, yet complex colonial history of the Democratic Republic of Congo, (DRC). His politically nuanced and culturally sensitive work explores the seismic shifts in economic, political and cultural identity in the DRC since colonization. Increasingly globalized in outlook, many in the DRC today are rejecting their ancestral heritage in favour of modernity, a conflict that fuels Kamuanga s work. The DRC is the world s largest exporter of coltan, a mineral critical to the production of computer chips and mobile phones. In all Kamuanga s works, the skin of each figure is embedded with integrated circuits, referring to the harsh conditions experienced by workers who mine coltan by hand. Eddy Kamuanga has been recognized internationally as one of the most interesting, young, contemporary African talents of today and his reputation is fast growing worldwide. His work has been shown across Africa, notably at Zeitz MOCAA, South Africa, and has been included in exhibitions in Europe and the United States, at institutions such as the Fowler Museum, UCLA, Los Angeles, (CA); the Hood Museum of Art, Dartmouth College, (NH); the Saatchi Gallery; and the Royal Academy of Arts, London. Eddy Kamuanga Ilunga is represented by October Gallery, London, UK.
This highly practical handbook is an exhaustive treatment of eddy covariance measurement that will be of keen interest to scientists who are not necessarily specialists in micrometeorology. The chapters cover measuring fluxes using eddy covariance technique, from the tower installation and system dimensioning to data collection, correction and analysis.With a state-of-the-art perspective, the authors examine the latest techniques and address the most up-to-date methods for data processing and quality control. The chapters provide answers to data treatment problems including data filtering, footprint analysis, data gap filling, uncertainty evaluation, and flux separation, among others. The authors cover the application of measurement techniques in different ecosystems such as forest, crops, grassland, wetland, lakes and rivers, and urban areas, highlighting peculiarities, specific practices and methods to be considered. The book also covers what to do when you have all your data, summarizing the objectives of a database as well as using case studies of the CarboEurope and FLUXNET databases to demonstrate the way they should be maintained and managed. Policies for data use, exchange and publication are also discussed and proposed.This one compendium is a valuable source of information on eddy covariance measurement that allows readers to make rational and relevant choices in positioning, dimensioning, installing and maintaining an eddy covariance site; collecting, treating, correcting and analyzing eddy covariance data; and scaling up eddy flux measurements to annual scale and evaluating their uncertainty.

The existence and crucial role played by large-scale, organized motions in turbulent flows are now recognized by industrial, applied and fundamental researchers alike. It has become increasingly evident that coherent structures influence mixing, noise, vibration, heat transfer, drag, etc... The accelera tion of the development of both experimental and computational programs devoted to this topic has been evident at several recent international meet ings. One of the first questions which experimentalists or numerical analysts are faced with is: how can these structures be separated from the background turbulence? This is a nontrivial task because the coherent structures are gen erally embedded in a random field and the technique used to determine when and where certain structures are passing, or their averaged characteristics (in the more probable or dominant role sense) is directly related to the definition of the coherent structure. Several methods or approaches are available and the choice of a particular one is generally dependent on the desired informa tion. This choice depends not only on the definition of the structure, but also on the experimental and numerical capabilities available to the researcher.
