The influence of the type of difficulty of a cognitive task on metacognitive activity (metacognitive experiences and metacognitive strategies) was studied in six-and eight-year-old children. Children had to make decisions about the correspondence of statements and drawings presented in pairs one after...

doi:10.1055/s-2008-1055082Flash stimulation of the isolated frog retina causes an increase in extracellular K + activity (Δa K) that can be recorded simultaneously with the local ERG by means of a double barrelled K + sensitive microelectrode in the electrophysiologically identified inner ...
The slowly varying component of solar X-rays has been studied through records of the satellite Explorer-30 instrumented by the U.S. Naval Research Laboratory. Correlations with plage areas, and flux at radiofrequencies have been studied. High flux values in the 8–20 Å and, still more, ...
This result agrees with the proposal that preferential equatorial attack of a nucleophile is caused by conformational factors related to a steroid non-steroid conformation equilibrium in thecis-isomers.[Journal Translation]C. AgamiT. RizkR. DurandP. Genestecanadian journal of chemistry...
Methane sulphonyl chloride, thionyl chloride and p-toluene sulphonyl chloride react with voachalotine (I) to give, in each case, the same cyclised dihydroindole compound: 2α-hydroxy-17-desoxyvincamajine(VI). At room temperature the same reagents give with affinisine (II) the expected deriva...
Starting from 2-phenyl-4-ethoxymethyleneoxazolin-5-one, reactions proceed, in addition, by loss of ethanol and α-pyridones are obtained.Maquestiau, A.Université de l‘Etat, Laboratoire de Chimie Organique, 7000 Mons (Belgique)Vanden Eynde, J. J....
buten-1-one, 4-amino-3-penten-2-one, various 3-aminocrotonic esters and amides react with 1-phenylpyrazolidin-3,5-dione to yield compounds resulting from the elimination of ammonia between the two precursors and the so obtained derivatives cyclize on heating to pyrano [2,3-c] pyrazoles....
