Archéologie de l'agripaume, du pot à la plante : céramologie, botanique et carpologie
2017
ZusammenfassungEine reliefverzierte Sigillataschüssel vom Typ Drag. 29b, die zum keramischen Fundmaterial einer jüngst imBereich der Altstadthalbinsel von Lyon durchgeführten Grabung stammt, weist eine Pflanzendarstellung als Reliefdekor auf, die so präzise ist, dass die dargestellte Pflanze von den Botanikern anhand der charakteristischen Blattform bestimmt werden konnte. Ihre Ansprache als Herzgespann oder Löwenschwanz (Leonurus cardiaca L.), einer zumindest seit der Antike bekannten und genutzten Heilpflanze, bietet die Gelegenheit, die medizinischen Wirkungen der Pflanze, ihre Anwendungen sowie ihre archäobotanischen Nachweise vorzustellen. Ferner wird der außergewöhnliche Charakter die…
Productions végétales, alimentation et élevage dans la vallée de la Moselle entre Metz et Thionville et dans les environs de la cité de Metz : l'appo…
2017
International audience; This paper deals with recently obtained archaeobotanical and archaeozoological results obtained from Gallo-Roman sites in the Moselle valley between Metz (Divodurum mediomatricorum) and Thionville and the adjacent areas. The results deriving from recent rescue excavations are giving evidence of Gallo-Roman agricultural practices in a time frame from the 2nd to the late 4th c. AD.

Sensory methodology developed for the investigation of sciaccarello wine concept
2004
<p style="text-align: justify;">The aim of the present work was to underline the existence of a sensory space relevant to Sciaccarello wines. Twenty-eight wines were selected for viticultural and enological characteristics, using 1/2 Sciaccarello/Non- Sciaccarello ratio. Sensory analyses (orthonasal then overall perceptions) were performed with a panel composed of seventeen judges. All of the judges were experienced in Sciaccarello wines knowledge. Statistical treatment by PCA was first carried out to display the consensus between the assessors. ANOVA was performed to discriminate accurate and inaccurate examples of Sciaccarello wines. This study demonstrated the existence of the sens…
How Does the pH of Tree Bark Change with the Presence of the Epiphytic Bryophytes from the Family Orthotrichaceae in the Interaction with Trunk Incli…
2021
The pH of tree bark is affected by many factors, amongst them epiphytic bryophytes changing in their active state environment. Thus, we hypothesized that bryophytes can change bark acidity, dependently of the inclination of the branches, as inclination affect the water regime and particle deposition. We measured the pH under bryophyte cushions and compared it to nearby naked bark. Additionally, we compared results with experimental bark covering with neutral cover. We found that the pH of naked bark declines with decreasing inclination of trunks. Although bryophyte cover did not generally change the pH of the bark, there was a significant interaction with inclination: with higher inclinatio…
Complete Genome Sequence of a New Ruminococcaceae Bacterium Isolated from Anaerobic Biomass Hydrolysis
2018
ABSTRACT A new Ruminococcaceae bacterium, strain HV4-5-B5C, participating in the anaerobic digestion of grass, was isolated from a mesophilic two-stage laboratory-scale leach bed biogas system. The draft annotated genome sequence presented in this study and 16S rRNA gene sequence analysis indicated the affiliation of HV4-5-B5C with the family Ruminococcaceae outside recently described genera.
Increase in midgut microbiota load induces an apparent immune priming and increases tolerance to Bacillus thuringiensis
2010
Summary The insect immune system is comprised of both humoral and cellular components that are mobilized in response to parasitic or pathogenic infections. Activation of the immune response implies a consid- erable expenditure of energy and that is why insects rely on inducible pathways that are activated after coming into contact with the pathogenic agent. Known as immune priming, insects can prolong the activation of the immune response and transmit their immune status to the next generation. Starting from a laboratory colony of the lepidopteran Spodoptera exigua and using the lytic zone assay as a measure of the immune status, we selected for a sub-colony with high levels of immune activ…
