Abstract The Ludwig–Soret effect is a phenomenon wherein thermal diffusion induced by temperature gradient. governing differential equation to explain this has been derived phenomenologically based on the Onsager theorem in non-equilibrium thermodynamics. In study, we applied grain-boundary-phase (GBP) model effect. This originally proposed for calculating amount of grain boundary segregation a...

this article has been formulated based on the strategic planning of the university. vision formulation has been done based on the model presented by j. collins and j. porras (1996). the model includes two sectors, which are core ideolgy and envisioned future. in this article the envisioned future of the university and its vision have been formulated. envisioned future itself is included in two ...

Chaotic oscillators with Coulomb-type friction were extensively studied in the past. However, these investigations mostly deal with rather complex mechanical models that are closely related to everyday’s engineering applications. In the present paper, we introduce a stick-slip oscillator consisting only of a spring and a block sliding on a rough surface, and the block is periodically forced. A ...

STATEMENT OF PROBLEM Elastomeric impression materials have been reformulated to achieve a faster set. The accuracy of fast-setting elastomeric impression materials should be confirmed, particularly with respect to disinfection. PURPOSE The purpose of this study was to assess the accuracy of 2 types of fast-setting impression materials when disinfected with acid glutaraldehyde. MATERIAL AND ...

An analytical method to evaluate propionylpromazine hydrochloride (PPZHCl) in tranquilizer formulations was developed using high-performance liquid chromatography (HPLC). During analysis of aged quality-control samples, a previously unreported chromatographic response was observed at a shorter retention time than PPZHCl. Further investigation of formulations stored in trap tap devices at temper...
