The observations have been modelled by effective Hamiltonians including a large number of resonances between interacting vibrational states. These CRDS spectra allowed to study the isotopic shifts in vibrational levels of ozone du to the homogeneous substitution 1603-1803Silvina Escudero...
This article describes the change in the basic properties of standard concrete subjected to 12 h freeze–thaw cycles. Basic properties considered are resistance to compression and other parameters describing concrete behavior in axial compression with axial and transverse expansion. Although 300 freeze...
The infectivity and hemagglutination titers of influenza viruses were studied after treatment at different pH values during 4 hours at 37 °C.Influenza viruses appeared to be acid-labile. The loss of infectivity of influenza viruses varied within each type, since strains of type B were more ...

Objectives The primary objective of this study was to determine the proportion of cases of gastro-enteritis due to rotavirus in children under 5 years of age consulting community physicians. A secondary objective was to compare the clinical characteristics of children with and without rotavirus acute ...

The convergentsynthesis of the ethyl ended surfactants is based on a one-pot reduction/alkylation of hemifluorinated thioacetate and glucosylated trishydroxymethyl acrylamidomethane (THAM) using NaBH4 in methanol. This "mild" alkylation was studied in order to improve yields and to pass up the use ...
