    Authors: Gerval, Jean-Pierre; Le Ru, Yann;

    International audience; This paper sets out the methods and the technologies used to design a captive portal to redirect users to the URL (Uniform Resource Locator) of a course taking place in a given room. The captive portal is designed on a Raspberry Pi 2 carrying an Apache HTTP (HyperText Transfer Protocol) server and using iptables for redirections. It has a web configuration interface, developed with AngularJS, which communicates through HTTP request to the server side, developed in PHP, following the principle of a REST (REpresentational State Transfer) architecture. In addition to redirect users to the URL of a course, the interface is configurable in two modes: 1) fixed URL that sets an URL to which the user is redirected automatically, 2) hosting a local website which is used to load a web site in zip format on the device and then redirect users to this web site even when the device is not connected to any Ethernet network.

    Authors: D. Chicouene;

    The various methods of mechanical removal of weeds in relation to their biology are reviewed. Depending on the stage of growth and type of weed, i.e. the depth at which new shoots can be formed and the ability to withstand burial, implements inflict damage on weeds in different ways: cutting, burial or uprooting. The various types of damage are exemplified. The three main methods of destruction are analysed and compared. These are: lethal damage, particularly effective in the case of plantlets; the exhaustion of reserves, effective where either deep or surface organs are targeted; and withering, of special interest where sub-surface parts are involved. Stored reserves can be depleted by either cutting the foliage, burying foliar parts or severely cutting up surface organs of propagation. Withering is accomplished by either cutting the roots, by exposing the roots to the air or by shaking out rootlets. It is shown that the kind of damage is strongly dependent upon the type of organ involved. Advances in our understanding of the way in which mortality occurs are discussed in the light of research.

    Authors: Svizzero, Serge;

    Abstract Purpose This chapter is about the theories explaining the transition from foraging to farming. It aims to establish which links exist between the traditional theories – based on push/pull models – and the micro-founded approaches developed since the 1980s. More precisely, it asks how the latter may contribute, as the former did, to defining a macro-narrative of the transition to farming. Methodology/approach While they were providing a global narrative of the Neolithic revolution, the push and pull models have been progressively dismissed. Recent research is diverse, but it is all based upon human behaviour or micro-founded. We critically examine three of these approaches which focus either on foraging behaviour, or on the initial domestication of plants and animals, or on the evolution of social institutions related to ownership. Findings We demonstrate that these recent micro-founded approaches only provide a partial vision of the transition to farming. Despite this limit, they conciliate push and pull explanations in a single framework. Moreover, they confirm a conclusion held by tenants of pull models: the transition to farming is more likely to have occurred in a resource-rich environment such as the one associated with complex hunter-gatherers. Some archaeological evidence from the Levant is provided to support our claim. Value This research chapter provides a useful overview of the differing approaches to the behavioural, environmental and economic factors that led to the shift to farming from foraging. Its value lies in the way it presents and evaluates differing positions derived from differing scales of analysis and types of evidence.

    Fichier auteur; International audience; Nano: a small prefix makes a big difference. Original concepts in food and agriculture have recently emerged following the discovery of the new properties of nanomaterials. For instance, the hydrophobic sheathing of leaves has been mimicked to coat food and agricultural materials at the nanoscale. Research in nanoscience has produced materials with unique properties such as nanotubes, nanofillers, nanoparticles, nanocomposites, nanoemulsions, nanoliposomes, nanoclusters and self-assembled nanoparticles. Nanoencapsulation of functional molecules in food matrices is a new formulation technique that enhances food quality and security. The hurdles previously observed during the fabrication of encapsulating nanostructures have been addressed. Research is actually aiming at developping novel nanodelivery vehicles, and evaluating their risks. In particular, localized delivery and controlled release of nutrients is a current topic (Figure 1). Nanofertilizers and nanopesticides has the potential to enhance agricultural productivity. However, the transfert of engineered nanoparticles in the food chain may induce a toxic risk. This book reviews the formation, synthesis, functionality, applications, regulation, safety and socio-economical aspects of nanoparticles in food and agriculture.

  • Authors: Wion, Anaïs;

    International audience; The medieval Ethiopian economy is another challenging subject to treat, for different reasons. Ethiopian economic history is not a new subject: Richard Pankhurst pioneered such work in the 1950s, with a focus on modern Ethiopia, and Donald Crummey did groundbreaking work, for the early modern period, in the 1980s and 1990s. But economic research specifically on the medieval period has developed very little. This chapter is therefore a first, albeit in what would seem to be a “traditional” field. Drawing methodologically and for relevant data on studies dealing with earlier and later periods, highlighting the economic aspects of scholarship on the medieval period, and mining primary sources where studies lack, it provides a synthetic picture of agriculture and animal husbandry as well as trade that encompasses, to the extent possible, Christian, Muslim, and local-religious societies in the variety of their ecological settings.

    International audience; For the last decade, the question of anthropocentric approaches has made its way through the research, and fully techno-centered approaches have been questioned. The integration of social relationships between the components of systems has already been identified as a crucial issue for the future development of reference architec-tures. However, the current research lacks a global approach based on both consideration of the human as an integrated agent of the system and the use of social concept to characterize inter-agents' relationships. The purpose of this paper is to bring an overview of these aspects' consideration in the manufacturing control architecture and to outline some guidelines allowing to revise the architecture of reference PROSA.

    Authors: Chastanet, Monique;

    En Afrique sahélienne, marquée dans son histoire par des crises alimentaires récurrentes, l'agriculture et la cueillette ont été des activités complémentaires jusqu'à ces dernières années. En pays soninké, en particulier, la cueillette est une pratique régulière et socialement organisée, qui procure des aliments de complément en période d'abondance et des nourritures de substitution en période de crise. En l'absence de famine, elle joue un rôle important dans l'équilibre nutritionnel. Cet ancien travail servile a progressivement concerné tous les groupes sociaux depuis la fin du XIXème siècle, participant ainsi d'une évolution plus générale de la société soninkée. Actuellement, cependant, on constate un recul de la cueillette, plus ou moins marqué selon les régions, recul qui est lié à la dégradation du couvert végétal et au changement des modes de vie. Cela est dû notamment dans la haute vallée du Sénégal, à la monétarisation de l'économie, avec l'essor des migrations de travail, et à la transformation du système de production, avec la création de périmètres irrigués. Cette tendance a sans doute été renforcée par le manque d'intérêt pour la cueillette dans les milieux de la recherche et du développement. Cette activité repose sur la connaissance de la végétation et sur différentes techniques de récolte et de préparation. Elle joue un rôle dans la gestion de l'environnement, au même titre que l'agriculture, l'élevage, la pêche ou la chasse. Cette pratique a aussi une dimension sociale et symbolique, comme le montrent les témoignages et les chants de cueillette. En tant que moyen de subsistance et signe de pauvreté, la cueillette peut être à la fois un objet d'éloge et de dénégation. En temps de crise, en effet, non seulement la survie est menacée mais aussi l'identité sociale. Cette perception ambigüe de la cueillette constitue l'arrière plan de sa dévalorisation et de son déclin actuels. Sans perdre de vue l'ambivalence de la cueillette en milieu soninké - comme ailleurs en Afrique -, on peut s'interroger sur les conséquences de son recul au niveau de la connaissance et de la protection de l'environnement. Le déclin de la cueillette va dans le sens de l'uniformisation des systèmes agricoles, tout en augmentant leur vulnérabilité aux risques écologiques et économiques. Avant que ne disparaissent ces savoir-faire et les différentes pratiques qui leur sont liées, ne faudrait-il pas les prendre en considération et les réévaluer ? Si oui, selon quelles modalités ? In the African Sahel the history of which is marked by recurring food crises, agriculture and food gathering have remained until recent years complementary activities. In the Soninke country, in particular, food gathering is a regular, socially organized practice, which provides complementary food in periods of plenty and food substitutes during times of crisis. When there is no famine it plays an important part in nutritional balance. This formerly servile work has progressively concerned all social groups since the end of the 19th century, being in that way part of a more global evolution of Soninke society. At present, however, there is a decrease in food gathering, which varies according to the region and is related to the degradation of the vegetation cover and changes in the way of life. In the high Senegal valley it is due, in particular, to the monetization of the economy with the increase in migration of the labour force, and the transformation of the production system with the creation of irrigated perimeters. This trend may well have been strengthened by the lack of interest given to this activity in the fields of research and development. Food gathering practices depend on the knowledge of the vegetation and on different harvesting and preparation techniques. Food gathering plays as much a part in the management of the environment as agriculture or breeding stock, fishing or hunting. These practices are also strongly imbued with social and symbolic meaning, as the oral statements and the food gathering songs show. As a means of subsistence and a sign of poverty during times of famine, it can be either considered praiseworthy or as something to be denied. When a crisis occurs not only is survival in jeopardy but also social identity. This ambiguous perception of food gathering is the backcloth to its present depreciation and its decline. Without losing sight of the ambivalence of this practice in the Soninke society - and in other African societies - the consequences of its decrease from the point of view of knowledge and preservation of the environment can be questioned. The decline of food gathering also reinforces the present trend for uniform agricultural systems and increases their vulnerability to different forms of ecological and economic risks. Before the disappearance of these skills with their related practices should not these same skills be taken into consideration and reassessed, and if so, how?

    Authors: Gerval, Jean-Pierre; Le Ru, Yann;

    International audience; This paper sets out the methods and the technologies used to design a captive portal to redirect users to the URL (Uniform Resource Locator) of a course taking place in a given room. The captive portal is designed on a Raspberry Pi 2 carrying an Apache HTTP (HyperText Transfer Protocol) server and using iptables for redirections. It has a web configuration interface, developed with AngularJS, which communicates through HTTP request to the server side, developed in PHP, following the principle of a REST (REpresentational State Transfer) architecture. In addition to redirect users to the URL of a course, the interface is configurable in two modes: 1) fixed URL that sets an URL to which the user is redirected automatically, 2) hosting a local website which is used to load a web site in zip format on the device and then redirect users to this web site even when the device is not connected to any Ethernet network.

    Authors: D. Chicouene;

    The various methods of mechanical removal of weeds in relation to their biology are reviewed. Depending on the stage of growth and type of weed, i.e. the depth at which new shoots can be formed and the ability to withstand burial, implements inflict damage on weeds in different ways: cutting, burial or uprooting. The various types of damage are exemplified. The three main methods of destruction are analysed and compared. These are: lethal damage, particularly effective in the case of plantlets; the exhaustion of reserves, effective where either deep or surface organs are targeted; and withering, of special interest where sub-surface parts are involved. Stored reserves can be depleted by either cutting the foliage, burying foliar parts or severely cutting up surface organs of propagation. Withering is accomplished by either cutting the roots, by exposing the roots to the air or by shaking out rootlets. It is shown that the kind of damage is strongly dependent upon the type of organ involved. Advances in our understanding of the way in which mortality occurs are discussed in the light of research.

    Authors: Svizzero, Serge;

    Abstract Purpose This chapter is about the theories explaining the transition from foraging to farming. It aims to establish which links exist between the traditional theories – based on push/pull models – and the micro-founded approaches developed since the 1980s. More precisely, it asks how the latter may contribute, as the former did, to defining a macro-narrative of the transition to farming. Methodology/approach While they were providing a global narrative of the Neolithic revolution, the push and pull models have been progressively dismissed. Recent research is diverse, but it is all based upon human behaviour or micro-founded. We critically examine three of these approaches which focus either on foraging behaviour, or on the initial domestication of plants and animals, or on the evolution of social institutions related to ownership. Findings We demonstrate that these recent micro-founded approaches only provide a partial vision of the transition to farming. Despite this limit, they conciliate push and pull explanations in a single framework. Moreover, they confirm a conclusion held by tenants of pull models: the transition to farming is more likely to have occurred in a resource-rich environment such as the one associated with complex hunter-gatherers. Some archaeological evidence from the Levant is provided to support our claim. Value This research chapter provides a useful overview of the differing approaches to the behavioural, environmental and economic factors that led to the shift to farming from foraging. Its value lies in the way it presents and evaluates differing positions derived from differing scales of analysis and types of evidence.

    Fichier auteur; International audience; Nano: a small prefix makes a big difference. Original concepts in food and agriculture have recently emerged following the discovery of the new properties of nanomaterials. For instance, the hydrophobic sheathing of leaves has been mimicked to coat food and agricultural materials at the nanoscale. Research in nanoscience has produced materials with unique properties such as nanotubes, nanofillers, nanoparticles, nanocomposites, nanoemulsions, nanoliposomes, nanoclusters and self-assembled nanoparticles. Nanoencapsulation of functional molecules in food matrices is a new formulation technique that enhances food quality and security. The hurdles previously observed during the fabrication of encapsulating nanostructures have been addressed. Research is actually aiming at developping novel nanodelivery vehicles, and evaluating their risks. In particular, localized delivery and controlled release of nutrients is a current topic (Figure 1). Nanofertilizers and nanopesticides has the potential to enhance agricultural productivity. However, the transfert of engineered nanoparticles in the food chain may induce a toxic risk. This book reviews the formation, synthesis, functionality, applications, regulation, safety and socio-economical aspects of nanoparticles in food and agriculture.
