Book Description
Synthèse consacrée aux végétaux ligneux d'ornement, fruitiers et forestiers, cet ouvrage sur la Filière pépinière, présente la filière professionnelle, son organisation, son poids économique en France et sur le plan international. Le volet technique, intégrant les plus récents acquis dans le domaine, s'étend de la production en pépinière jusqu'à la plantation : sélection variétale, techniques culturales, matériels spécifiques. La qualité du produit et la protection de l'environnement sont largement abordées avec une description complète de l'éventail réglementaire. Ces thèmes majeurs sont illustrés d'exemples concrets issus de la recherche ou des entreprises. Innovant et très complet, ce volume est devenu rapidement une référence pour les professionnels, enseignants et étudiants de la filière de la pépinière et du paysage.

Book Description
The largest part of the world’s food comes from its soils, either directly from plants, or via animals fed on pastures and crops. Thus, it is necessary to maintain, and if possible, improve the quality—and hence good health—of soils, while enabling them to support the growing world population. The Soil Underfoot: Infinite Possibilities for a Finite Resource arms readers with historical wisdom from various populations around the globe, along with current ideas and approaches for the wise management of soils. It covers the value of soils and their myriad uses viewed within human and societal contexts in the past, present, and supposed futures. In addition to addressing the technical means of maintaining soils, this book presents a culturally and geographically diverse collection of historical attitudes to soils, including philosophical and ethical frameworks, which have either sustained them or led to their degradation. Section I describes major challenges associated with climate change, feeding the increasing world population, chemical pollution and soil degradation, and technology. Section II discusses various ways in which soils are, or have been, valued—including in film and contemporary art as well as in religious and spiritual philosophies, such as Abrahamic religions, Maori traditions, and in Confucianism. Section III provides stories about soil in ancient and historic cultures including the Roman Empire, Greece, India, Japan, Korea, South America, New Zealand, the United States, and France. Section IV describes soil modification technologies, such as polymer membrane barriers, and soil uses outside commercial agriculture including the importance of soils for recreation and sports grounds. The final section addresses future strategies for more effective sustainable use of soils, emphasizing the biological nature of soils and enhancing the use of "green water" retained from rainfall.

Book Description
Chemical Fertilizers is a collection of papers that covers the advancement in the research of chemical fertilizer technology. The coverage of text includes papers that tackle the concerns in utilizing chemical fertilizers, such as food and fertilizer in developing countries, and the physical-chemical studies on decomposition reactions and the safe handling of ammonium nitrate-bearing fertilizers. The selection also covers the issues about the production of chemical fertilizers, including technological progress in the production of urea and graphic method for calculating formulations in complex fertilizers production. The book will be of great use to chemists, botanists, agriculturists, and horticulturists.

Book Description
La peau - Structure et physiologie, ouvrage de référence destiné aux professionnels de la dermo-cosmétique et de l'esthétique, s'enrichit d'une nouvelle édition revue et augmentée afin de proposer, en plus de la synthèse des éléments fondamentaux de la biologie cutanée et de ses pathologies, les mises à jour intervenues ces dernières années dans le domaine en constante évolution que constitue la recherche en dermatologie. L'ouvrage met en avant, dans un premier temps, la structure et les composants de la peau au niveau cellulaire et moléculaire (épiderme, derme, hypoderme, vascularisation et innervation cutanée, annexes cutanées). Puis, les propriétés de la peau, en liaison avec ses différentes fonctions, sont abordées : thermorégulation, information sensorielle et protection contre les agressions extérieures. Enfin, une large part est faite aux effets du soleil sur la peau et au vieillissement cutané. Dotée de références, d'un index élargi et de nombreuses nouvelles illustrations, cette deuxième édition de La peau - Structure et physiologie est un livre unique sur le marché qui correspond, par son contenu et son approche didactique, aux programmes des diplômes d'esthétique et de cosmétique, en particulier celui du BTS. Il s'adresse également aux futurs professionnels de la santé tels que les étudiants en biologie, médecine, pharmacie et soins infirmiers, et à tout public désireux de se former et de s'informer sur les caractéristiques et les fonctions de la peau.

Book Description
Interdependence between species is a law of nature. The degree of this interdependence is vividly evident in the plant-microbial world. Indeed, there is no axenic plant in nature and one finds various forms of interac tions between these two kingdoms ranging from completely innocuous to obligate parasitic. Most of these interactions are poorly understood at the molecular and physiological levels. Only those few cases for which a molecular picture is emerging are discussed in this volume. With the advent of recombinant DNA technology and the realization that some of these interactions are very beneficial to the host plant, a spate of activity to understand and manipulate these processes is occurring. Microbes interact with plants for nutrition. In spite of the large number of plant-microbe interactions, those microbes that cause harm to the plants (i. e. , cause disease) are very few. It is thus obvious that plants have evolved various defense mechanisms to deal with the microbial world. The mecha nisms for protection are highly diverse and poorly understood. Some pathogens have developed very sophisticated mechanisms to parasitize plants, an excellent example for this being crown gall caused by a soil bac terium, Agrobacterium tumefaciens. A remarkable ingenuity is exhibited by this bacterium to manipulate its host to provide nitrogenous compounds which only this bacterium can catabolize. This is carried out by a direct gene transfer mechanism from bacteria to plants.
