Atlas de pétrographie: Minéraux de roches observés en lame mince
de W. S MacKenzie (Ed. Pearson Education Ltd.) Isbn : 2225839956
30.49 € / 200 FF
Cet atlas réunit 230 microphotographies de roches d'une remarquable qualité chromatique. Chaque espèce minérale fait l'objet d'une description succincte, assortie de données caractéristiques : formule chimique, système cristallographique, signe optique et indice de réfraction. Certaines de ces espèces sont représentées au sein de plusieurs coupes, de manière à illustrer leurs variations d'aspects d'une roche à l'autre. Le clichage, réalisé en lumière polarisée non analysée ou entre polariseurs croisés, permet d'apprécier le relief optique des minéraux, leur couleur en lumière naturelle et leurs teintes de biréfringence. L'orientation des lames minces par rapport à la lumière polarisée concourt à mettre en évidence les macles, les clivages, l'isotropie des minéraux cubiques ou coupés perpen...

10.00 € / 65.6 FF
Ce document fait partie d'une série de fascicules intitulée Les méthodes d'analyse en milieu marin. Il présente les méthodes analytiques développées au laboratoire de Biogéochimie des Contaminants Organiques (Département Biogéochimie et écotoxicologie de l'IFREMER), pour l'analyse quantitative, dans les sédiments marins, de polychlorobiphényles, pesticides organochlorés, hydrocarbures aromatiques polycycliques, hétérocycles soufrés, et leurs homologues alkylés. Ces méthodes sont utilisées dans le cadre du Réseau National d'Observation de la qualité du milieu marin à des niveaux de détection de traces et ultra-traces (ug/kg et ng/kg), ainsi que pour des projets de recherche et d'étude visant à une meilleure compréhension du comportement et du devenir de ces contaminants en milieu marin.

Tropical Residual Soils
de (Ed. Geological Society Publishing House) Isbn : 1897799381
69.06 € / 453 FF
Tropical residual soils differ from transported soils which are principally derived from coastal, fluvial, wind blown or glacial processes. In the tropics, residual soils probably form that largest group with which the engineer has to deal. Being formed in situ these soils have particular characteristics that distinguish them from material deposited from transported soils. The aim of the original Working Party Report, published in 1990, was to establish a resonably comprehensive guide to the engineering classification and characteristics of tropical residual soils. The Working Party comprised academics, researchers, contractors and consultants known to have been particularly concerned with tropical residual soils. This edition makes the report available in book form for the first time. Th...

Soil Liquid Phase Composition
de V. V. Snakin, A.A. Prisyazhnaya, E. Kovacs-Lang (Ed. Elsevier Science Ltd) Isbn : 0444506756
99.99 € / 655.89 FF
The liquid phase of soil (soil solution) is a very thin, penetrating and all-embracing water layer. It has the most extensive surface among the biosphere components and interacts with all these components. Presented in this work is a new complex approach developed for soil liquid phase investigation that is based on in situ measurements. Investigation of the soil liquid phase can be of great significance in environmental research. This volume sums up the vast experience of the authors' research into soil liquid phase composition in various ecosystems of Central and Eastern Europe. It describes the methodological basics of soil liquid phase research: methods of soil solution extraction, the main problems of application of ion-selective electrodes for immediate in situ assessment of ionic a...

Fine grained sediment : transport of suspended particles
de Jean-Pierre Dupont (Ed. Quae éditions) Isbn : 2759200213
6.86 € / 45 FF
The behaviour of suspended matter in the Seine estuary is due to the high organic content, the morphology of the dyked channel flow, the erosion/settlement processes and hydrodynamical parameters which come from tidal cycles and meteorological events. SPM discharge from the catchment area are focused during flood stages. One part of these materials moves to the mouth estuary and then are exported in the outer estuarine zone of Baie de Seine. The other part settles on banks and hydrological extends and then is transfered to the mouth estuary or exported by dredging. The turbidity maximum zone of the mouth estuary changes according to hydrodynamical effects. Turbidity and hydrodynamical recordings give us fundamental data for the development of hydrosedimentological models of the estuary.

Nitrogen Fixation at the Millennium
de (Ed. Elsevier Science Ltd) Isbn : 0444509658
99.99 € / 655.89 FF
Hardbound. The turn of the millennium from the twentieth to the twenty-first century provides an occasion to review our understanding of a biological process, biological nitrogen fixation, that is of prime importance for the continued survival of mankind. This process has provided a basis for maintaining soil fertility since the beginning of organised agriculture, yet its very existence was confirmed only just over a century ago. In the intervening years, an enormous intellectual effort has dispersed much of the mystery surrounding biological nitrogen fixation. Biological fixation is widely exploited in agriculture, as are nitrogen fertilisers prepared for the last hundred years under extreme conditions of temperature and pressure. However, despite all our efforts, the fundamental nature ...

Soil, Fertilizer, and Plant Silicon Research in Japan
de Jian Feng Ma, Eiichi Takahashi (Ed. Elsevier Science Ltd) Isbn : 0444511660
99.99 € / 655.89 FF
Hardbound. Silicon (Si) plays a significant role in the resistance of plants to multiple stresses including biotic and abiotic stresses. Silicon is also the only element that does not damage plants when accumulated in excess. However, the contribution of Si to plant growth has been largely ignored due to its universal existence in the earth's crust. From numerous intensive studies on Si, initiated in Japan about 80 years ago, Japanese scientists realized that Si was important for the healthy growth of rice and for stability of rice production. In a worldwide first, silicon was recognized as a valuable fertilizer in Japan. The beneficial effects of Si on rice growth in particular, are largely attributable to the characteristics of a silica gel that is accumulated on the epidermal tissues i...
