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 ...

The conclusion is offered that, in accordance with logic, test coupons should no longer be taken in the web, but rather in the flanges of rolled shapes.P. Dumonteilcanadian journal of civil engineering
The role of chemical heterogeneity has been analysed through the experimental and calculated results. Finally, a good correlation has been obtained between measurements and calculation of the deformation during cooling of a 3D "croissant" shaped specimen.L Josephbibliogr...

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 ...
On the other hand, the European Union has progessively taken charge of the issue of family support, which has brought about an harmonisation of national family policiesGerbino T.CCastello GBibliogr
Wheat is the second most produced cereal in the world, important for food, feed and many industrial uses. Understanding of the mechanisms involved in grain development is fundamental for developing high quality wheat. In particular, detailed knowledge of the wheat grain physiology and molecular ...
The reaction takes place under steric control. The consecutive elimination reaction proceeds by a mechanism of intramolecular nucleophilic substitution.doi:10.1002/hlca.19750580846Gabriel DousseJacques SatgéHelvetica Chimica Acta
