Book excerpt: LE MECANISME DE FRAGMENTATION NUCLEAIRE A HAUTE ENERGIE EST ENCORE LARGEMENT INCOMPRIS. DANS LE PRESENT TRAVAIL NOUS ESSAYONS DE CARACTERISER LES PROCESSUS QUE LE GOUVERNENT EN CONFRONTANT LES MOMENTS DES DISTRIBUTIONS DE MASSE (CHARGE) FINALES OBTENUS A L'AIDE DE DIFFERENTS MODELES AVEC L'EXPERIENCE ET LES RESULTATS DONNES PAR LES MODELES DE PERCOLATION QUI SONT EN TRES BON ACCORD AVEC LES DISTRIBUTIONS EXPERIMENTALES MESUREES JUSQU'ICI ET PREDISENT DES PROPRIETES D'UNIVERSALITE EFFECTIVEMENT OBSERVEES. NOUS MONTRONS QUE LA DESAGREGATION BINAIRE STANDARD VALABLE A BASSE ENERGIE NE PERMET DE REPRODUIRE NI LES PROPRIETES D'UNIVERSALITE ATTENDUES, NI LE CARACTERE MULTIFRACTAL (INTERMITTENT) DES DISTRIBUTIONS. PAR CONTRE, CES PROPRIETES PEUVENT ETRE REPRODUITES DE FACON SATISFAISANTE PAR UN MECANISME DE CASSURE SPECIFIQUE QUI DONNE DES DISTRIBUTIONS MOYENNES DE FRAGMENTS PROCHES D'UNE LOI DE PUISSANCE DONT L'EXPOSANT EST PROCHE DE 2. CE COMPORTEMENT EST OBSERVE DANS LA PERCOLATION AU POINT CRITIQUE. NOUS MONTRONS QU'IL POURRAIT EXISTER UNE CORRELATION ENTRE LA GENERATION DE FLUCTUATIONS DE NATURE MULTIFRACTALE (INTERMITTENTE) ET UNE LOI DE PUISSANCE DE CE TYPE. NOUS EN CONCLUONS QU'UN COMPORTEMENT EN LOI DE PUISSANCE DES DISTRIBUTIONS POURRAIT ETRE UN CRITERE SUFFISANT POUR L'OBSERVATION DU CARACTERE INTERMITTENT DES FLUCTUATIONS ET DISCUSSIONS DU CONTENU EN INFORMATION DES OBSERVABLES PHYSIQUES PERMETTANT DE CARACTERISER CE PHENOMENE

This book was released on 1999-10-31 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to give the reader up to date infonnation on some of the more exciting developments that have taken place at the leading edge of fragrance and flavour research. Chapter one gives the reader a rnpid excursion through the chronological landmarks of fragrance and flavour materials and sets the scene for the remaining nine chapters which cover topics that are at the forefront of modem research. Chapter two looks at the total synthesis of synthetically interesting perfumery naturnl materials. This chapter aims to highlight the creative and elegant chemistry that has been performed by some of the worlds greatest chemists in their quest to synthesise one of the five naturnl products reviewed in the chapter. The chapter fits in with the forward looking theme of the book as it will hopefully inspire other chemists that are interested in synthesising natural products to produce elegant new, or industrially applicable routes to these and other perfumery materials. Chapter three looks at the growing area of interest in asymmetric fragrance materials. The chapter focuses on the use of the metal-BINAP catalytic system for the preparation of fragrance and flavour ingredients. Environmental considerations are now an integrnl and vital part of planning any new industrial chemical process. Chapter four aims to give the reader an insight into the wide-ranging and often readily applicable chemistry that is currently available for the installation of environmentally friendly chemical processes.

Available in PDF, EPUB and Kindle. Book excerpt: Alphaherpesviruses are a fascinating group of DNA viruses that includes important human pathogens such as herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV): the causative agents of cold sores, genital ulcerous disease, and chickenpox/shingles, respectively. A key attribute of these viruses is their ability to establish lifelong latent infection in the peripheral nervous system of the host. Such persistence requires subversion of the host's immune system and intrinsic antiviral defense mechanisms. Understanding the mechanisms of the immune evasion and what triggers viral reactivation is a major challenge for today's researchers. This has prompted enormous research efforts into understanding the molecular and cellular biology of these viruses. This up-to-date and comprehensive volume aims to distill the most important research in this area providing a timely overview of the field. Topics covered include: transcriptional regulation, DNA replication, translational control, virus entry and capsid assembly, the role of microRNAs in infection and oncolytic vectors for cancer therapy. In addition there is coverage of virus-host interactions, including apoptosis, subversion of host protein quality control and DNA damage response pathways, autophagy, establishment and reactivation from latency, interferon responses, immunity and vaccine development. Essential reading for everyone working with alphaherpesviruses and of interest to all virologists working on latent infections.
