A method was established for the simultaneous determination of germanium and tin in one run by ion chromatography. Using a selected eluent, Ge and Sn were separated on a bifunctional ion-exchange column, followed by a postcolumn chromogenic reaction and spectrophotometric detection at 520 nm. The whole procedure was completed within 5 min with high sensitivity and selectivity at the low-/zg/1 l...

Controller Area Network (CAN) is a fieldbus network suitable for small-scale Distributed Computer Controlled Systems, being appropriate for transferring short real-time messages. However, CAN networks are also known to present some reliability problems, which can lead to an inconsistent message delivery, thus to an unreliable behaviour of the supported applications. In this paper, a set of atom...

The main purpose of the research was to develop the micromodel of biocompatible titanium nitride nanocoating deposited on polymer by pulsed laser deposition method in blood chambers of Polish ventricular assist devices: POLVAD and POLVAD_EXT. The analysis of the parameters of micromodel crucial for the phenomenon of loss of cohesion occurring between coating and substrate was carried out as wel...

What are the necessary and sufficient conditions to experience pleasure in interpersonal communication and dealing with art, science, and philosophy - this is what the theory of informational needs (TIN) suggested eleven years ago is about. At the same time, at the beginning of this century, several lines of research have emerged. Neuroaesthetics has been established; the discovery of the mirro...

The complex behaviour of metals under severe thermal and stress environments is influenced markedly by their elastic properties. Indeed the response of a material tc~ an applied stress is always determined by the elastic constants and their pressure derivatives. Furthermore, both the mechanical and thermodynamic equation;$ of state of a metal that contains dislocations require detailed knowledg...

Hierarchical nanotubular TiN was prepared by magnesiothermic reduction of titania replicas of a cellulose substance (filter paper), which possessed high surface area (31.4 m(2) g(-1)), and was demonstrated to be a promising electrode material due to its electrochemical performances.

Carbon 1s photoelectron spectra for 2-butyne (CH3C≡CCH3) measured in the photon energy range from threshold to 150 eV above threshold show oscillations in the intensity ratio C2,3/C1,4. Similar oscillations have been seen in chloroethanes, where the effect has been attributed to EXAFS-type scattering from the substituent chlorine atoms. In 2-butyne, however, there is no high-Z atom to provide a...

Nanostructured TiN/TiB2/Fe–Cr–Ni composite powder has been prepared via high energy ball milling. Ti and BN powders are reacted to form uniform mixture of TiN and TiB2 within 2 h of milling by a mechanically activated self-sustaining reaction (MSR). The crystallite sizes of TiN nd TiB2 are about 7 and 16 nm, respectively, after 32 h of milling. Through liquid phase sintering and optimizing the ...

Why do some victims elicit outpourings of sympathy from those who are unaffected, while others do not? The authors propose a theoretical framework for making sense of the vicissitudes of sympathy based on the interaction between two qualitatively different mental processes. One, which the authors term “sympathy,” is caring but immature and irrational. The other process, which the authors term “...
