this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

Oxide materials such as Al2O corundum has a great influence on the mechanical and oxidation properties of refractory or refractory materials. In this paper, the effect of Al2O3 powder density, apparent porosity, linear shrinkage, and oxidation resistance of SiC composite refractory materials is investigated. Meanwhile, the compressive and flexural strengths were investigated before and after he...

The Kolakoski sequence $S$ is the unique element of \(\left\lbrace 1,2 \right\rbrace^{\omega}\) starting with 1 and coinciding its own run length encoding. We use parity lengths particular subclasses initial words \(S\) as a unifying tool to address links between main open questions - recurrence, mirror/reversal invariance asymptotic density digits. In we prove that recurrence implies reversal ...
