Conceptual Basis, Formalisations and Parameterization of the Stics Crop Model

The STICS crop model has been developed since 1996 at INRA in collaboration with other research and technical institutes. The model syntheses, illustrates and concretizes an important part of the French agronomic knowledge as a point of view on the field and cropping systems working. The formalisations of the STICS crop model presented in this book can be considered as references used in the framework of crop sciences. The book arrangement relies on the way the model designs the crop-soil system functioning, each chapter being devoted to a set of important functions such as growth initiation, yield onset, water uptake, transformation of organic matter etc. One chapter deals with the cropping system and long term simulations and the final chapter is about the involvement of the user in terms of option choices and parameterization. If this book is mainly intended for scientists who use the STICS model, it can also be useful for agronomists, crop modellers, students and technicians looking for elementary formalizations of the crop-soil system functioning.

The Seine River Basin

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...

Flow and Transformations in Porous Media

Flow and Transformations in Porous Media

Fluid flow in transforming porous rocks, fracture networks, and granular media is a very active interdisciplinary research subject in Physics, Earth Sciences, and Engineering. Examples of natural and engineered processes include hydrocarbon recovery, carbon dioxide geo-sequestration, soil drying and wetting, pollution remediation, soil liquefaction, landslides, dynamics of wet or dry granular media, dynamics of faulting or friction, volcanic eruptions, gas venting in sediments, karst development and speleogenesis, ore deposit development, and radioactive waste disposal. Hydrodynamic flow instabilities and pore scale disorder typically result in complex flow patterning. In transforming media,...

This study, based on a literature review and simulations, shows the efficiency of cover crops at catching nitrate in most agriculture situations. It also analyzes both the negative impacts they can have and the ecosystem services they can provide. The introduction of a cover crop between two main crops helps catch the soil mineral nitrogen before the period of drainage and consequently reduces nitrate leaching and nitrate concentration in the drainage water. This study allows quantifying the efficiency of cover crops at catching nitrate and optimizing their implantation conditions over a large range of French pedoclimatic conditions. The presence of high nitrate levels in surface and ground waters, due to excessive nitrogen fertilization and natural production of nitrate by soil organic matter mineralization, is a double challenge for public health and environment protection.

Forests, Carbon Cycle and Climate Change

The results presented in this book summarize the main findings of the CARBOFOR project, which brought together 52 scientists from 14 research units to investigate the effects of future climate on the carbon cycle, the productivity and vulnerability of French forests. This book explains the current forest carbon cycle in temperate and Mediterranean climates, including the dynamics of soil carbon and the total carbon stock of French forests, based on forest inventories. It reviews and illustrates the main ground-based methods for estimating carbon stocks in tree biomass. Spatial variations in projected climate change over metropolitan France throughout the 21st century are described. The book ...

Fulcanelli and the Alchemical Revival

Sheds new light on the identity of the alchemist Fulcanelli • Provides new understanding of the relationships between the most important figures of the esoteric milieu of Paris in the first half of the 20th century • Includes a wealth of rarely seen documents, photos, and letters Fulcanelli, operative alchemist and author of The Mystery of the Cathedrals and The Dwellings of the Philosophers--two of the most important esoteric works of the twentieth century--remains himself a mystery. The true identity of the man who allegedly succeeded in creating the philosopher’s stone has never been discovered, despite ardent searches by many--even the OSS (the wartime U.S. intelligence agency, lat...

Diabetes mellitus (DM) is a chronic metabolic disorder manifested by an enhanced blood glucose levels. DM is categorized into type 1 diabetes and Type 2 diabetes. Metformin is an anti-diabetic medication that is related to the biguanide class. Metformin is the first treatment for Type 2 DM because of its efficacy, safety and minimal risk of hypoglycemia. Sulfonyl ureas namely glipizide and glyburide activate insulin secretion from pancreatic beta cells. Meglitinides, like nateglinide and repaglinide also activate insulin secretion, but their action is short - lived compare to sulfonyl ureas. Thiazolidine diones (TZDs) along with pioglitazone and rosiglitazone activate insulin sensitivity par...
