When applied to skin, particulate matter has been shown accumulate in hair follicles. In addition follicles, the skin topography also incorporates trench-like furrows where particles potentially can accumulate; however, have not as thoroughly investigated a drug delivery perspective. Depending on body site, combined follicle orifices cover up 10% of surface, while easily 20%, reaching depths ex...

Our main target and concept was to develop a method for the determination of most prescribed antilipemic drug, atorvastatin, together with its related substances, single sample preparation during chromatographic run, in shortest possible period time, lowest mobile phase consumption. A new rapid, simple atorvastatin specified impurities developed, using different columns. With this powerful core...

In this paper we show that there is a Lipatov bound for the radius of convergence for superficially divergent one-particle irreducible Green functions in a renormalizable quantum field theory if there is such a bound for the superficially convergent ones. The radius of convergence turns out to be min{ρ, 1/b1}, where ρ is the bound on the convergent ones, the instanton radius, and b1 the first c...

Superficially coloured lead crystal glass was obtained by ion-exchange with silver. Both red and yellow ruby colouring were achieved by the presence of small silver particles (colloids) dispersed into the ion-exchanged glass surface. Direct silver ion-exchange of the glass yielded yellow colouring (optical absorption around 410 nm). Silver ion-exchange of lead glass previously doped with a redu...

This article presents a series of simulation experiments investigating the interaction of memory and analogy-making in the AMBR model. This interaction leads to blending between superficially dissimilar episodes as a result of the established analogical mapping between them and of superficially and structurally dissimilar episodes as a result of a double analogy with a third episode. The condit...
