Identification of bound alcohols in soil humic acids by gas chromatography-mass spectrometry

2000

International audience; Humic acids are complex, partly macromolecular, yellow-brownish substances occurring in soils, waters and sediments. In order to shed some light on their molecular structure, crop humic acids were cleaved by alkaline hydrolysis (KOH). The products were fractionated by thin layer chromatography to give mono-alcohols which were analysed as acetate derivatives by gas chromatography coupled to mass spectrometry. Linear alcohols, sterols, stanols and plant-derived triterpenoid alcohols were identified by co-injection of pure standards and by comparison with literature data. These findings imply that alcohols could have been incorporated into the humic matrix by esterifica…

The Kleiner Feldberg Cloud Experiment 1990. An overview

1994

An overview is given of the Kleiner Feldberg cloud experiment performed from 27 October until 13 November 1990. The experiment was carried out by numerous European research groups as a joint effort within the EUROTRAC-GCE project in order to study the interaction of cloud droplets with atmospheric trace constituents. After a description of the observational site and the measurements which were performed, the general cloud formation mechanisms encountered during the experiment are discussed. Special attention is given here to the process of moist adiabatic lifting. Furthermore, an overview is given regarding the pollutant levels in the gas phase, the particulate and the liquid phase, and som…

The multiple facets of Cajal-Retzius neurons.

2021

ABSTRACTCajal-Retzius neurons (CRs) are among the first-born neurons in the developing cortex of reptiles, birds and mammals, including humans. The peculiarity of CRs lies in the fact they are initially embedded into the immature neuronal network before being almost completely eliminated by cell death at the end of cortical development. CRs are best known for controlling the migration of glutamatergic neurons and the formation of cortical layers through the secretion of the glycoprotein reelin. However, they have been shown to play numerous additional key roles at many steps of cortical development, spanning from patterning and sizing functional areas to synaptogenesis. The use of genetic l…

Crémations et monument funéraire campaniformes à Genlis « le Nicolot » (Côte-d'Or, France)

2021

The building of the high-speed rail track linking the Rhine to the Rhone led to the discovery of two Bell Beaker burials in an Iron Age cemetery located in the plain to the east of Dijon. The Tilles plain is an alluvial environment, shaped by the valleys of the Tille and the Ouche and populated since Late Prehistory, particularly during the Bell Beaker and Early Bronze periods, which have yielded settlements located on the rivers. These burials are the first funerary features discovered in the area.The two Bell Beaker cremation burials excavated at Genlis "le Nicolot" are remarkable, as still too little is known of the funerary practices of the period in the east of France and in particular…

LE SITE CAMPANIFORME DE LUX LA PERROUZE (SAÔNE-ET-LOIRE)

2014

Le site de Lux La Perrouze (Saône-et-Loire) apporte de nouvelles données sur le Campaniforme bourguignon par la découverte d’une petit ensemble céramique remarquablement homogène, contenu dans le remplissage de quatre structures en creux. Cet ensemble se compose essentiellement de céramique commune, mais quelques gobelets décorés sont également à signaler. L’étude de ce mobilier permet de souligner la remarquable homogénéité des productions du groupe campaniforme bourguignon-jurassien tant pour leur chronologie que pour leurs affinités culturelles. The site of Lux La Perrouze (Saône-et-Loire) has provided new data on the Bell Beaker culture of Burgundy by the discovery of a small and remark…

Le Vignaud 3, Chemin du Puits Neuf (Langlade, Gard) : du Fontbouisse au Campaniforme : premiers résultats

2008

Excavations at the site of Le Vignaud 3, Langlade, situated at the heart of the Vaunage, have revealed a settlement constructed in dry stone which fits perfectly within the local Fontbouisse tradition (as exemplified at Boussargues, Le Rocher-du-Causse, etc.). As well as being of architectural interest, particularly in relation to the internal organisation of enclosed sites, the site also produced a large number of finds (pottery, lithics, animal bones, etc.) which provide evidence of Fontbouisse culture and Bell Beaker occupation. The stratigraphic evidence relating these two cultures, and the results of the preliminary analysis of the finds, provide new evidence concerning the adoption of…

L'HABITAT DU BRONZE ANCIEN DANS L'EST DIJONNAIS (CÔTE D'OR, BOURGOGNE) : ARCHITECTURE, TERROIR ET TERRITOIRE

2015

The first discoveries concerning the Early Bronze Age in the region of Genlis (Burgundy, Côte d’Or) were madeduring the construction of the A39 motorway, the first major development project to be associated with archaeological monitoring. Excavations made by H. Dartevelle in the early 1990’s revealed two large areas of settlements with two ellipsoidal houses, smaller buildings and satellite structures (Dartevelle 1992). The site of Genlis-Izier, “Le Joannot” remained the only local reference for early Bronze Age habitats until the early 2010’s, when the construction of the L.G.V. Rhin-Rhône considerably updated this data. This article provides a summary of new and existing discoveries, and …
