The use of trace elements to promote biogas production features prominently on the agenda for many biogas-producing companies. However, the application of the technique is often characterized by trial-and-error methodology due to the ambiguous and scarce basic knowledge on the impact of trace elements in anaerobic biotechnologies under different process conditions. This book describes and defines the broad landscape in the research area of trace elements in anaerobic biotechnologies, from the level of advanced chemistry and single microbial cells, through to engineering and bioreactor...

Annual Reports in Organic Synthesis 2004 provides an organized annual review of synthetically useful information that proves beneficial to organic chemists, both specialists and nonspecialists in synthesis.

Information appears as promptly as possible after the close of the abstracting period and is presented in an organized manner.

Chapters I to III are organized by reaction type.
Chapter IV deals with methods of synthesizing heterocyclic systems.
Chapter V covers the use of protecting groups.
Chapter VI deals with those synthetically useful transformations that do...

This handy reference tool is an organized annual review of synthetically useful information. It abstracts synthetic reactions from the major chemistry journals of the past year and includes all reactions and methodsthat are new and reasonably general. The reactions are presented in a convenient pictorial format designed for rapid visual retrieval of information.

The Journal of the American Chemical Society has aptly described this publication as an"aid to the harassed organic chemist who cannot keep up with the never-diminishing stream of new primary literature"and hails...

A l'origine Prolog avait pour but non pas de crA(c)er un langage de programmation mais de traiter les langues naturelles, en l'occurrence le franAais. Ce projet a donnA(c) naissance A un Prolog prA(c)liminaire fin 1971 et un Prolog plus dA(c)finitif fin 1972. Cet article relate les diffA(c)rentes A(c)tapes du projet et dA(c)crit en dA(c)tails les deux versions de Prolog. Nous avons aussi jugA(c) bon de dA(c)crire les systA]mes-Q, qui a jouA(c) un rAle important dans la genA]se de Prolog et d'ajouter un appendice avec six exemples de programmes pour se familiariser avec le Prolog actuel.
