Book Description
L’utilisation directe d’hydrogène comme vecteur énergétique pour des applications embarquées doit actuellement faire face à l’absence d’infrastructure de distribution et à des difficultés technologiques liées au problème du stockage de l’hydrogène. Une étape transitoire possible avant le passage à une économie «direct hydrogène» consiste à produire l’hydrogène à bord du véhicule à partir des carburants automobiles traditionnels. Le reformage assisté par plasma hors équilibre constitue une alternative au reformage catalytique qui, bien que largement utilisé à l’échelle industrielle, reste peu adapté aux contraintes des systèmes embarqués. Ce travail s’inscrit dans le cadre de recherches menées depuis une quinzaine d’années par le Centre Énergétique et Procédés, dans le domaine de la conversion d’hydrocarbures par plasma. L’objectif de ce travail a été la caractérisation précise du dispositif de reformage assisté par plasma, à travers différentes études paramétriques (influence de l’écoulement – géométrie de l’électrode cylindrique, régime de fonctionnement, pression, polarité – et influence des conditions chimiques – mélange initiale, débit total, puissance électrique, nature du carburant précurseur), conduites tant sur le plan expérimental que théorique. Une étude du comportement de la torche dans les conditions non-réactives (eau, air) a d'abord été effectuée. La réaction de reformage a ensuite été étudiée suivant des conditions variées (POx, SR, ATR) et à l'aide d'essence SP95, d'éthanol, d'E85 et de gazole ; prouvant le caractère versatile de la technologie. Un modèle simple d'arc a été développé dans le cas de l'air. La modélisation du réacteur a ensuite concerné différents aspects. L'étude de l'écoulement, tout d'abord, a permis de montrer que le mélange homogène entre les trois réactifs (air, eau, octane) était rapidement atteint lors de leur injection dans le réacteur, conférant au système une symétrie axiale. L'étude d'un modèle cinétique 1D a ensuite mis en évidence le rôle des radicaux dans l'activation de la réaction de reformage, et a donné lieu à une étude paramétrique poussée (mélange initial, débit total, puissance injectée, schéma cinétique utilisé). Un modèle couplé prenant en compte l'interaction entre l'écoulement 2D axisymétrique et les réactions de cinétique chimique a enfin été élaboré, mettant l'accent sur le déroulement de la réaction dans l'ensemble du réacteur.

Book Description
Agro-industrial wastes are end-products emerging after industrial processing operations and also from their treatment and disposal e.g. solid fruit wastes and sludge. The agro-industrial wastes are often present in multiphase and comprise multicomponent. Nevertheless, these wastes are a goldmine as they possess valuable organic matter which can be diverted towards high value products ranging from polymers to antibiotics to platform chemicals. There have been plenty of books published on bioenergy, enzymes and organic acids, among others. However, this emerging field of biochemical has not yet been covered so far which is an important entity of the biorefinery model from waste biomass and needs to be understood from fundamental, applied as well as commercial perspective which has been laid out in this book.

Book Description
Agricultural and forest pests lead to many plant diseases resulting in poor yield and productivity. Traditionally, chemical pesticides have been used to control these pests. However, the adverse health impacts of chemical pesticides have triggered parallel research in safe biological options. Nevertheless, biocontrol has come a long way ever since the commercialisation of the first Bacillus thuringiensis based biopesticide (sporeine) in the 1940s, however, still there are research gaps. New knowledge and practical experiences have been added over the last few decades. This book reviews research on biological control agents, including bacterial, fungal and viral biopesticides along with their advanced formulation options.

In this book, the authors present topical research in the study of the synthesis, properties and applications of citric acid. Some of the topics discussed include fungal and yeast production of citric acid; mitochondrial production and applications in food and pharmaceutical industries; synthesis of the CuO/CeO2 catalytic system by polymerisation with citric acid; citric acid as a useful tool in artificial enamel formation and regeneration; the impact of citrate on glycolysis in brain tumours and applications of citrus fruits and their extracts for detection of food poisoning caused by bacteria.

Book Description
The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.

Book Description
Anionic polymerisation techniques offer powerful methods for the controlled manipulation of macromolecular architecture, and are still today unique for the synthesis of a wide variety of model polymeric materials. This book presents current research data from across the globe in the study of polymer initiators including: advanced organocobalt initiators in radical polymerisation; surface-initiated polymerisation techniques; citric acid and biopolymers; oliogomeric azo-initiators for grafting of polymers on clay surfaces and photopolymerisation.

Book Description
This book highlights that Soviet economic planners and politicians must come to recognize the need to make fundamental changes, not simply incremental refinements, in the failing Soviet system. It examines the dynamics of the process of perestroika and the complexity of individual economic issues.

Book Description
"The Ladybird is a long tale or novella by D. H. Lawrence. It was first drafted in 1915 as a short story entitled The Thimble. Lawrence rewrote and extended it under a new title in December 1921 and sent the final version to his English agent on 9 January 1922. It was collected with two other tales, The Captain's Doll and The Fox, and the three novellas were then published in London by Martin Secker in March 1923 under the title The Ladybird and in New York by Thomas Seltzer as The Captain's Doll in April 1923."
