Current-Mode Circuits Based on SIMO OTA: Review and New Applications in Filters
(Hikari, 2009-11-06)
The paper deals with design of low-order RC filters working in current mode (CM). As the basic building blocks, transconductors (OTA) with single input and
multiple outputs are used. One-loop, two-loop and multi-loop ...
Electronically adjustable mixed-mode implementations of the jerk functions
(Hikari Ltd., 2009-06-22)
In this paper the several structures of the third-order nonlinear oscillator with electronically adjustable parameters are presented. A brief numerical analysis including the computation of the largest Lyapunov exponent ...

Utilizing of square wave voltammetry to detect flavonoids in the presence of human urine
(MDPI, 2007-10-15)
About biological affecting of flavonoids on animal organisms is known less, thus we selected flavonoids, flavanones and flavones, and their glycosides, which were examined as potential inducers of cytochrome(s) P450 when ...
Flow Injection Analysis Coupled with Carbon Electrodes as the Tool for Analysis of Naphthoquinones with Respect to Their Content and Functions in Biological Samples
(MDPI, 2006-10-01)
Naphthoquinones are one of the groups of secondary metabolites widespread in
nature, where they mostly appear as chromatic pigments. They embody broad-range of
biological actions from phytotoxic to fungicidal. An anticancer ...
Shapes of Differential Pulse Voltammograms and Level of Metallothionein at Different Animal Species
(MDPI, 2007-10-19)
Metallothioneins play a key role in maintaining homeostasis of essential metals and in protecting of cells against metal toxicity as well as oxidative damaging. Excepting humans, blood levels of metallothionein have not ...
Aggregation behavior of novel hyaluronan derivatives-a fluorescence probe study
