Le bassin de l’Orgeval, situé à 70 km à l’est de Paris dans un triangle de 104 km2, fait partie d’un réseau d’observatoires nationaux et internationaux. Grâce aux mesures faites pendant 50 ans (1962-2012), il permet de mieux comprendre les transferts d’eau et de polluants, l’état et la disponibilité des ressources en eau, et de prévenir les risques extrêmes, autant d’enjeux du développement durable.
Les propriétés biologiques des organismes « microbiens » (bactéries, archées et leurs virus), objets d’étude de la microbiologie, sont au centre d’un éventail d’activités humaines depuis les applications industrielles jusqu’aux bio- et nanotechnologies. La microbiologie est également partie prenante des différents secteurs de la sauvegarde de l’environnement. Enfin, les approches génomiques et métagénomiques ont révélé la place essentielle, voire primordiale des micro-organismes dans l’ensemble du monde vivant. Cet ouvrage en deux couleurs présente les aspects fondamentaux de la structure, de la physiologie et de la biologie moléculaire des organismes appartenant aux domaines des bactéries, des archées et de leurs virus ainsi que les méthodologies d’études de la microbiologie. Des encarts sur les aspects historiques de la microbiologie et ses applications biomédicales et industrielles ponctuent le cours. Des ressources numériques téléchargeables sur le site dunod.com complètent l'ouvrage (photographies, schémas, vidéos).

Continuous Multivariate Distributions, Volume 1, Second Edition provides a remarkably comprehensive, self-contained resource for this critical statistical area. It covers all significant advances that have occurred in the field over the past quarter century in the theory, methodology, inferential procedures, computational and simulational aspects, and applications of continuous multivariate distributions. In-depth coverage includes MV systems of distributions, MV normal, MV exponential, MV extreme value, MV beta, MV gamma, MV logistic, MV Liouville, and MV Pareto distributions, as well as MV natural exponential families, which have grown immensely since the 1970s. Each distribution is presented in its own chapter along with descriptions of real-world applications gleaned from the current literature on continuous multivariate distributions and their applications.
This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the...
In this volume expert authors review current research on diverse aspects of the interactions which occur in the rhizosphere between the host plant and the microorganisms. The chapters focus on specific phenomena, from the biochemical and genetical level to complex inter-organism communication.
A comprehensive handbook outlining state-of-the-art analytical techniques used in geomicrobiology, for advanced students, researchers and professional scientists.
Petroleum-based industrial products have gradually replaced products derived from biological materials. However, biologically based products are making a comeback--because of a threefold increase in farm productivity and new technologies. Biobased Industrial Products envisions a biobased industrial future, where starch will be used to make biopolymers and vegetable oils will become a routine component in lubricants and detergents. Biobased Industrial Products overviews the U.S. land resources available for agricultural production, summarizes plant materials currently produced, and describes prospects for increasing varieties and yields. The committee discusses the concept of the biorefinery and outlines proven and potential thermal, mechanical, and chemical technologies for conversion of natural resources to industrial applications. The committee also illustrates the developmental dynamics of biobased products through existing examples, as well as products still on the drawing board, and it identifies priorities for research and development.
Nowadays the term dose-response is used in many different contexts and many different scientific disciplines including agriculture, biochemistry, chemistry, environmental sciences, genetics, pharmacology, plant sciences, toxicology, and zoology. In the 1940 and 1950s, dose-response analysis was intimately linked to evaluation of toxicity in terms of binary responses, such as immobility and mortality, with a limited number of doses of a toxic compound being compared to a control group (dose 0). Later, dose-response analysis has been extended to other types of data and to more complex experimental designs. Moreover, estimation of model parameters has undergone a dramatic change, from strugglin...
