Humusica 2, article 19: Techno humus systems and global change - Conservation agriculture and 4/1000 proposal
2018
International audience; Philosophy can overlap pedology. It is not casual that life begins and finishes in the soil. We separated the concepts of Humipedon, Copedon and Lithopedon. Some sections were dedicated to the founders of the movement for a new type of agriculture (agroecology). They simply proclaim to accompany the process of natural evolution instead of spending a lot of energy in hunting competitor organisms with pesticides or boosting the soil with mineral fertilisation and tillage. The core of the article is built on a biological concept of the soil and shows researches supporting this view. After pointing to the soil structure and illustrating its natural genesis, explaining wh…
New P-T-X conditions for the formation of gem tsavorite garnet in the Voi area (southwestern Kenya)
2018
International audience; Tsavorite nodules-bearing deposits from southwestern Kenya are located in the Kurase Group, a metasedimentary unit of the Neoproterozoic Metamorphic Mozambique Belt. This unit is composed of graphitic paragneisses intercalated with metacarbonates and metaevaporites, surrounded by migmatites. The rocks underwent high grade metamorphism at 615-600 Ma. The main goal of this work is to link tsavorite formation to the metamorphic evolution of the Kurase Group. The new thermobarometric data indicate widespread granulite facies conditions at 800 +/- 50 degrees C and 10 +/- 1 kbar, with no significant difference between the tsavorite-bearing metasediments and the surrounding…
la prospection systématique d’un fond de rivière : l’exemple du Doubs
2020
La présentation des méthodes mises en œuvre et des résultats obtenus à l’occasion d’une opération de prospection subaquatique systématique menée sur la rivière Doubs, en amont de Verdun-sur-le-Doubs (Saône-et-Loire), illustre en grandeur réelle l’intérêt de la démarche adoptée, fondée sur des principes simples, dans la perspective d’un inventaire systématique du patrimoine fluvial immergé. La diversité des vestiges découverts et leur répartition sur la longue durée en soulignent la pertinence mais également, s’il en était encore besoin, la réalité du formidable potentiel archéologique que recèlent les cours d’eau. The presentation of the methods used and results obtained during a systematic…
Phytotoxicity of Essential Oils on Selected Weeds: Potential Hazard on Food Crops
2018
The chemical composition of winter savory, peppermint, and anise essential oils, and in vitro and in vivo phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, and Echinochloa crus-galli) and food crops (maize, rice, and tomato), have been studied. Sixty-four compounds accounting for between 97.67&ndash
De la maison au " village" . Les origines de la morphologie de l'habitat dispersé dans les montagnes de la Savoie du nord
2002
Dans les hautes vallées savoyardes, le peuplement d'avant l'invasion touristique était caractérisé par une implantation en hameaux dispersés à travers le territoire communal. Dispersion relative en Savoie du sud (Maurienne, Tarentaise, Combe de Savoie) où les hameaux étaient fédérés par un « chef-lieu » qui était un véritable bourg ; dispersion fréquemment absolue en Savoie du nord (Faucigny, Chablais), où le chef-lieu n'avait souvent pas plus d'importance que les écarts. C'est aux massifs mo...
Les rapports aux savoirs du sachant : Le savoir mis en circulation par l’enseignant-tuteur EPS dans l’entretien-conseil : une étude de cas en didacti…
2021
Our work consists in making an inventory of the transmissions that take place between the P.E. tutor and his trainee during the counselling interview. This official process concludes the day of the trainee's visit to the situation and brings professional knowledge into play. In the intervention professions, each actor acts in a singular way with the public he is responsible for. This activity is nourished by the references that have structured his conceptions and the events that have built his professional experience. However, when the tutor suddenly changes his intentions, other singularities must be taken into account. The way in which he positions himself in relation to what is expected …
Teaching swimming at primary school level : a significant difficulty for the subject
2020
This thesis seeks to identify and understand, from the epistemological and methodological field of psychoanalysis, the nature of the difficulty in teaching swimming encountered by four P.E. primary school teachers. It is based on a trainer’s observation witnessing the embarrassment of P.E. teachers confronted with this discipline and with a lack of ‘solutions’ to deal successfully with this professional difficulty. The clinical methodological device consists in the construction of four cases based on the interpretative analysis of the subject’s speech, collected through individual clinical interviews. This collection is completed by a clinical observation time during teaching sessions for t…
Aceites esenciales: productos antimicrobianos y antioxidantes naturales en la industria agroalimentaria
2020
[ES] Los consumidores son conscientes del peligro derivado del uso de antioxidantes y antimicrobianos sintéticos en la industria agroalimentaria, demandando alternativas más seguras y ecológicas. En este estudio, se ha determinado la actividad antioxidante de aceites esenciales comerciales mediante el método DPPH y su efecto antimicrobiano frente a la bacteria Pseudomonas syringae y el hongo fitopatógeno Fusarium oxysporum a través del empleo del método estandarizado de disco. Los aceites esenciales de clavo, ajedrea, canela y orégano, así como carvacrol, mostraron la máxima actividad antioxidante, comparable a antioxidantes establecidos. El aceite esencial de gaulteria fue el más potente i…

La didactique clinique comme mode d'accès aux savoirs des enseignants en ÉPS : le cas de l'enseignement du judo
2017
Este estudio exploratorio y comprensivo destaca los saberes personales de los docentes transmitidos durante el EPS. La investigación presenta tres viñetas didácticas clínicas de los docentes especialistas en judo. Los resultados muestran que estos saberes personales se construyeron durante la práctica de este deporte cuando estos docentes eran jóvenes practicantes. Se destaca el papel de lo que «se encuentra presente por la experiencia» («déjà-là expérientiel») y de los efectos en las concepciones de los docentes, en relación con el conocimiento personal de estos. Teniendo en cuenta los efectos decisivos de «lo experiencial y conceptual», proponemos algunas líneas de trabajo para la formaci…
