Abstract

Si la tendance au regroupement des industries métallurgiques en pôles de taille mondiale paraît inéluctable, il faut tout faire pour que cette évolution n'entraîne pas un affaissement de la France dans ce domaine clé. En effet, si les grands acteurs mondiaux de la Métallurgie ne peuvent plus s'appuyer,comme encore récemment, sur une recherche et un enseignement publics français forts, l'ensemble de notre système s'asséchera et migrera ailleurs. Qui plus est, la perte de substance ira bien au-delà de la R&D, frappant en particulier le tissu de nos PMI/PME. L'Académie des technologies et l'Académie des sciences présentent ici une analyse de la Métallurgie française, établie par un groupe d'experts animé par André Pineau, de l'Académie des technologies, et Yves Quéré, de l'Académie des sciences. Cet ouvrage synthétique, complété par des annexes numérisées, décrit en premier lieu la Métallurgie comme science, en tant que telle, en lien fort avec l'ingénierie, ou génie métallurgique. Il établit ensuite un diagnostic de la situation pour les divers grands secteurs industriels ainsi que pour la recherche et l'enseignement. L'ambition est ici de montrer que la Métallurgie constitue une discipline scientifique à part entière, présente dans des champs innombrables de l'industrie, où elle est source de progrès et réservoir d'emplois ; et de rappeler qu'il faut du temps pour construire des compétences indispensables, tant scientifi ques que techniques, qu'un rien suffi t à détruire. Le rapport montre également que la Métallurgie a perdu, en France, une grande part de sa substance, en raison à la fois de multiples réorganisations industrielles récentes et d'un désengagement du monde académique, largement dû aux effets de mode. C'est pourquoi des mesures urgentes, dans l'enseignement, la recherche universitaire et industrielle, l'information du public, la sensibilisation des décideurs et des acteurs… doivent être impérativement prises. Devant la gravité des évolutions recensées, qui rejaillissent notamment sur les emplois, les compétences, la R&D…, les deux académies proposent aux décideurs, publics et privés, une stratégie déclinée en une série de recommandations : dans chaque domaine est décrit l'état actuel et sont proposées des pistes de développement scientifi que et appliqué. Perdre une position de pôle dans ces domaines est dangereux ; en prendre une de leader est un défi à relever. Nous sommes actuellement à ce tournant et, en cela, nous sommes sans doute condamnés à l'excellence.

Abstract

"This book has been prepared with the aim to present the application of these two state-of-the art technologies in agricultural sciences and food technology, and to explain the protocols for analyses of different plant, animal, microbiological and food samples as well as for different biotechnology procedures. Selected methods and protocols which are used in plant stress physiology, weed science, fruit breeding research, microbial ecology, plant virus and fungus diagnostics, phytobacteriology, fishery, food biochemistry, food materials and food technology are described. Special adaptation of certain protocols is required for application in each of these sciences, for every type of GMO organism, food technology raw material, and food technology product, as well as for every type of bacteria, virus, fungus or fungus-like organism, for each type of raw material in terms of plant host species, plant organs, year period and conditions in the laboratory. Application of molecular methods, primarily qPCR, and Raman microscopy/ spectroscopy in agricultural and food sciences provides substantial opportunity for increased production efficiency, food safety, better product quality and improvement of plant and animal health. This book is aimed for students, scientists and professionals working in the field of agriculture and food technology."

Abstract

Adhesive abilities of insects, spiders and reptiles have inspired researchers for a long time. All these organisms show outstanding performance, particularly for force, adhesion and climbing abilities, relative to their size and weight. Scientists have focused on the gecko’s adhesive paw system and climbing abilities. Its adhesion mechanism has been an important topic of research for nearly 150 years. However, certain phenomena of geckos are still not fully understood and represent today the main challenge in several scientific discussions that aim to better understand their adhesive ability. The manuscript deals with the influence of surface roughness on the gecko’s adhesion on the inverted surface of Poly(methyl meth-acrylate) (PMMA) and glass, of PMMA with different surface roughness, on the gecko’s maximum normal adhesive force. In general, the adhesive structure and mechanism of an animal could be connected to the micro-structured roughness of natural substrata (e.g. plant surfaces) in the natural environment. This manuscript focuses on the nanometer scale, which is involved in everything from gecko spatulae to the waxy nanotubules of the lotus leaf, to the fibroin protein materials that constitute spider silks. In general, spider silks display superior mechanical properties, but only in the last few decades, researchers investigated various types of silks and evaluated their very different mechanical properties. The dragline and the flag silks (or radial and circumferential) of orb weaving spiders have been characterized in scientific literature while, to our knowledge, few studies have been conducted on bundles, which connect the cocoons of Meta menardi to the ceiling of caves.

Abstract

The Special Issue aims to provide a complete exploration of the scientific principles related to processing, fermentation/malting, and nutrition of cereal grains. It also describes their physical and chemical characteristics and explains how these properties relate to health and nutritional value of the final grain-based products. Indeed, while grains remain the world’s largest food yield—with more than 2.4 billion metric tons produced annually—consumer demands are on the rise for grain products sustainable from an environmental, social and economic viewpoint, in order to meet the growing demand for healthy and nutritious foods.

Abstract

Consumers trust is a key factor in dealing with rising concerns about food safety and food quality, but only few studies have dealt with consumer attitudes and none of them has tried to model the process of consumer response. This book reports the main findings of an european project aimed at analysing trust along the food chain and its relationship with food risk communication. The papers collected investigate the mechanisms that determine the social diffusion of trust, examining the interplay of the psychological, sociological and economic factors; and analyze the impact of the food risk communication policies on consumers and producers and on the society as a whole.

Abstract

Food-derived bioactive peptides or dietary peptides are increasingly becoming recognized as major food compounds for human health promotion, which prevent the occurrence of chronic diseases through their impacts on the gastrointestinal, cardiovascular, immune, and nervous systems. Further bioactive peptide discoveries are essential for maintaining human health and commercial development in the area of functional foods and nutraceuticals. This Special Issue covers a wide range of research topics specifically on food-derived bioactive proteins and peptides including the in-vitro and in-vivo evaluation of biological activities, bio-accessibility, intestinal absorption, bioavailability, the effect on chronic diseases, and the modulation of human nutrition.
