The maternal and paternal influences on early embryo survival in rainbow trout are not established. The purpose of this study was to determine whether variability in the survival of rainbow trout embryos could be attributed to either the female or male parent. Gametes from individual female and male rainbow trout were used in single pair matings to produce families Ž whose survival was followed...

Motile bacteria sense their physical and chemical environment through highly cooperative, ordered arrays of chemoreceptors. These signalling complexes phosphorylate a response regulator which in turn governs flagellar motor reversals, driving cells towards favourable environments. The structural changes that translate chemoeffector binding into the appropriate kinase output are not known. Here,...

Whole mounts and cross-sections of embryos from three species of teleost fish were immunostained with the HNK-1 monoclonal antibody, which recognizes an epitope on migrating neural crest cells. A similar distribution and migration was found in all three species. The crest cells in the head express the HNK-1 epitope after they have segregated from the neural keel. The truncal neural crest cells ...

https://doi.org/10.5128/ERYa19.09This study deals with mediated receptive multilingualism in comprehension of Finnish by Russian-dominant upper secondary school students Estonia. The objective the experiment is to analyse whether Russian as L1 and Estonian L2, no prior knowledge Finnish, can understand utilizing their command Estonian. research this field enhance understanding processes acquiri...

1.2. Properties of M0,n ⊂ M0,n. (1.2.1) M0,n has a natural moduli interpretation, namely it is the moduli space of stable n-pointed rational curves. (1.2.2) Given power series f1(z), . . . , fn(z) which we think of as a one parameter family in M0,n one can ask: What is the limiting stable n-pointed rational curve in M0,n as z → 0 ? There is a beautiful answer, due to Kapranov [Ka1], in terms of...
