The Database and Expert Systems Applications (DEXA) conferences have established themselves as a platform for bringing together researchers and practitioners from various backgrounds and all regions of the world to exchange ideas, experiences and opinions in a friendly and stimulating environment. The papers presented at the conference represent recent developments in the field and important steps towards shaping the future of applied computer science and information systems. DEXA covers a broad field: all aspects of databases, knowledge based systems, knowledge management, web-based systems, information systems, related technologies and their applications. Once again there were a good number of submissions: out of 183 papers that were submitted, the program committee selected 92 to be presented. In the first year of this new millennium DEXA has come back to the United Kingdom, following events in Vienna, Berlin, Valencia, Prague, Athens, London, Zurich, Toulouse, Vienna and Florence. The past decade has seen several revolutionary developments, one of which was the explosion of Internet-related applications in the areas covered by DEXA, developments in which DEXA has played a role and in which DEXA will continue to play a role in its second decade, starting with this conference.

Focusing on soil management strategies for farmers during winter, this book also serves researchers exploring soil organic matter metrics. It highlights the role of soil particulate organic matter as a fertility index and evaluates the effectiveness of hairy vetch ecotypes as a winter cover crop against winter rye, offering insights into sustainable agricultural practices.

The book delves into the geological characteristics of lamprophyre dikes, highlighting their unique physical and chemical traps. It outlines three distinct stages of mineralization: the first involves high-temperature conditions leading to native gold and silver alongside primary sulfide minerals; the second stage occurs at lower temperatures, resulting in secondary sulfate minerals; and the final stage features calcification linked to supergene alteration, producing calcite and uranium minerals.

Dieses Buch richtet sich an Landwirte und Anbauer, die Lösungen für die Bodenbewirtschaftung im Winter suchen. Es bietet auch Informationen für Forscher zur Messung der organischen Bodensubstanz und untersucht die Rolle von Haarwicken-Ökotypen als Winterdeckfrucht im Vergleich zu Winterroggen.
