Book Description
The success of the previous Conferences on Energy from Biomass, held in Brighton 1980and Berlin 1982, and the continued interest among European countries, encouraged theCommission of the European Communities to organise the third conference on this areaof energy production. It brought together about 500 experts from many countries thuspresenting an international forum for discussion of the most recent advances in researchand development, manufacture and industrial applications.

Energy from Biomass
Author: Willeke PalzPublisher: Springer Science & Business Media
ISBN: 9400977638
Category : Technology & Engineering
Languages : en
Pages : 189
Book Description
This l:::ook comes as part of a new series on Solar Energy R+D, includlng Biomass which is carried out by the Euro:pean Community.. The commission of the European Comrmmities' Directorate General (XII) for Science, Research and Developnent is currently implementing, on a cost-sharing basis, a solar energy R+D pro;Jranune through contracts with European industry, research institutions and uni versi ties. This prcgrarrrrne includes a very strong acti vi ty on Biomass. Besides general R+D work on all aspects of Biomass growth and utilization which is reported elsewhere in this series, the Canmission is currently starting a new activity on Pilot Plants based on the use of Biomass for energy purp:Jses, and in particular on methanol prcx:luction from wood. The commission considers that the subject of methanol prcxiuction from wood offers llnp:Jrtant prospects for application wi thin the European Canmilllity and in other parts of the world, in particular some of the developing countries & The state of art in Europe In this field is still considered to be very high as a result of related work which was performed in Europe during ~vorld War II and the time before.

Rapport Du Groupe de Travail de la FAO Sur L'évaluation Des Petits Pélagiques Au Large de L'Afrique Nord-occidentale
Author: FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa. MeetingPublisher: Food & Agriculture Org.
ISBN: 9789250058887
Category : Business & Economics
Languages : en
Pages : 252
Book Description
The Group assessed the status of the small pelagic resources in Northwest Africa and make projections on the development of the status of the stocks and on future effort and catch levels. As a precautionary measure, the catch level for this species should not exceed the average over the last three years of 115 000 tonnes. For bonga, the recommendation from 2006 is maintained as no new information is available on this species, and the Working Group recommended that the catch level should not exceed 42 000 tonnes. - Le Groupe a examine l'etat actuel des ressources de petits pelagiques en Afrique nord occidentale en fait des projections sur le developpement, l'effort futur et les niveaux de capture. Comme mesure de precaution, le niveau de capture pour cette espece ne devrait pas depasser la moyenne de 115 000 tonnes des trois dernieres annees. Pour l'ethmalose, la recommandation de 2006 est maintenue car aucune information nouvelle n'est disponible pour cette espece et le Groupe de travail a recommande que le niveau de capture ne depasse pas 42 000 tonnes"

Estimating Tree Biomass Regressions and Their Error
Author: Publisher:
ISBN:
Category : Forest biomass
Languages : en
Pages : 316
Book Description
Proceedings of a workshop co-sponsored by the USDA Forest Service, the State University of New York, and the Society of American Foresters. Presented were papers on the methodology of sample tree selection, tree biomass measurement, construction of biomass tables and estimation of their error, and combining the error of biomass tables with that of the sample plots or points. Also presented were papers on various aspects of biomass research currently being conducted in the United States, Canada, and abroad.
