Local adaptation resulting from selection pressure acts on heritable characters and is a major force shaping the phenotypic diversity of natural populations. Currently, numerous questions exist surrounding the impact of selection on the evolution of genes involved in the structure of adaptive traits, ...
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 ...

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, ...
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 inflam...
Finally, polarisation mode dispersion and vectorial modulational instability in the microstructured fibre are studied.Lavender, PaulNotes Bibliogr
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
It has been proposed, mainly on the basis of spectral evidence, that the addition of chlorine top-benzoquinone gives thecis-dichloride, and that in an alcoholic solution this substance isomerizes to thetrans-dichloride, which then enolizes to the corresponding hydroquinone. Upon reexamination of...
