present one only those objects have been retained which were most easily interpreted by the greatest number of children. Some objects which might seem to be very familiar to adults had to be rejected. For instance, an anchor which was easily recognised by boys presented difficulties to girls and had to be discarded. The objects retained are either easy to interpret or else capable of a varied i...

We examined the actin-nucleating activity in polymorphonuclear leukocyte lysates prepared at various times after chemotactic peptide addition. The actin nucleation increases two- to threefold within 15 s after peptide addition, decays to basal levels within 90 s, and is largely independent of cytoplasmic calcium fluxes. The peptide-induced nucleation sites behave as free barbed ends and therefo...

We derive a kinetic Monte Carlo algorithm to simulate flow-induced nucleation in polymer melts. The crystallisation kinetics are modified by both stretching and orientation of the amorphous chains under flow, which is modelled by a recent non-linear tube theory. Rotation of the crystallites under flow is modelled by a simultaneous Brownian dynamics simulation. Our kinetic Monte Carlo approach i...

The purpose of this study is to look into post-Greimasian semiotics and investigate how this tensive model can be applied to Rustam and Sohrab in Ferdowsi’s Shahnameh and its translation by Arnold. The tensive model, considering the two dimensions of intensity and extent, investigates meaning formation and production. Accordingly, this research intends to analyze the semiotic ...

Formation of binary cluster ions from polar vapours is considered. The effect of vapour polarity on the size and composition of the critical clusters is investigated theoretically and a corrected version of classical KelvinThomson theory of binary ion-induced nucleation is derived. The model predictions of the derived theory are compared to the results given by classical binary homogeneous nucl...
