The Bag Index (TBI) is a novel approach using standardized materials (i.e., commercial tea bags) to evaluate organic matter decomposition by determining two indexes: the early stage decomposition constant k (k_TBI) and litter stabilization factor S (S_TBI).k_TBI is defined as the decomposition constant of an asymptote model describing the decomposi
Biological and Immunological Characterization of a Functional L-HN Derivative of Botulinum Neurotoxin Serotype F
Botulinum neurotoxins (BoNTs) can cause nerve paralysis syndrome in mammals and other vertebrates.BoNTs are the most toxic biotoxins known and are classified as Class A biological warfare agents.BoNTs are mainly divided into seven serotypes A-G and new neurotoxins BoNT/H and BoNT/X, which have similar functions.BoNT proteins are 150 kDa polypeptide
La construction de la tour Saint-Laurent du palais des Papes (1353-1357) : nouveaux regards sur un chantier
The opportunity here to study the Saint-Laurent tower of the Avignon Palais des Papes (1353-1357), undertaken between 1997 and 1999 in the context of a collective research project, was provided by restoration work.This project has enabled the team to retrace and to characterize the functioning of one of the major building programmes of its period i
Experimental study of the effectiveness of the removal of virus hepatitis B, C and parvovirus B19 by the fractionation of blood plasma with ethanol
The purpose of the study was to assess the effectiveness of the removal of nucleic acids (NA), Hepatitis B (HBV) and C (HCV) viruses and parvovirus B19 (B19V) from blood plasma fractions obtained by alcohol separation.The studies were performed in a model experiment by fractionation normal pool plasma donation contaminated with virus-containing sam
