Three methods for the cleavage of 2,4-dinitrophenylhydrazones are described: 1) Reduction of the DNPH with Na 2 S 2 O 4 , followed by hydrolysis; 2) Reduction of the DNPH with SnCl 2 .2H 2 O, followed by hydrolysis; 3) Displacement of the DNPH by means of a large excess of ...
G Chiltz, P Goldfinger, G Martens - 1957 - onlinelibrary.wiley.com Abstract The photochemical reaction between gaseous Cl 2, C 2 Cl 4 and C 2 Cl 5 H has been further investigated. From the general reaction scheme previously proposed equations have been calculated and tested experimentally ...
We also proposed a new directional QSAR approach combining a D-optimal design, PLS and principal component analysis that proved in combination with NGPLS to be efficient decision making tools for the lead optimisation process.Martínez-Tur, Vicente...
Sapere Aude: More than ever the injunction of the Age of Enlightenment applies to our globalised world reaching a crossroads. The internationalisation of China has changed the rules of the geopolitical stakes between China, the European Union and the United States. In addition to the positive ...
The newly identified APOA5 is a crucial determinant of triglyceride levels and therefore the study of the factors regulating its gene expression is of significant importance. The first part of our studies aims at determining the rôle of APOA5 in infla...
Napus genotype and the structure of F& hybrids. The effet of the hybrid structure was considerable : at the meiosis of AAC triploid hybnrids, resulting from crosses between B. Napus and B. Rapa, recombination rates were from 1. 8 to 3. 4 fold higher than in AACC tetrploid hybrids, ...
A biometrical study of the calyx of 178 flowers ofFittonia vershaffeltiiat all developmental stages has allowed conclusions to be drawn about their morphogenesis. Their various parts grow according to simple allometric relations, and this growth is linked with the cauline plastochron. The equations ...
Les conséquences de l’altération visuelle se traduisent par une augmentation significative de la consommation de biens et services médicaux et donc par des coûts plus élevés que ceux que l’on observe dans un groupe de sujets du même âge.G...
The intermediate 4-methyl-8-formylpyrene (m.p.: 93-94°) was isolated. U. V. Spectra of the new polymethylpyrenes are given.John StewartBulletin Des Sociétés Chimiques Belges
For every cases, we rely on a procedural approach based on progressive deformation, and eventually, on-the-fly refinement of the geometry just before the rendering stage.doi:10.1016/j.respe.2011.03.029Rivera DíazRoberto Carlogrenoble
