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 ...

Lactoferrin Isolation Using Monolithic Column Coupled with Spectrometric or Micro-Amperometric Detector
(MDPI, 2008-01-24)
Lactoferrin is a multifunctional protein with antimicrobial activity and others to health beneficial properties. The main aim of this work was to propose easy to use technique for lactoferrin isolation from cow colostrum ...
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 ...
Amperometric Sensor for Detection of Chloride Ions
(MDPI, 2008-09-15)
Chloride ion sensing is important in many fields such as clinical diagnosis, environmental monitoring and industrial applications. We have measured chloride ions at a carbon paste electrode (CPE) and at a CPE modified with ...
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 ...
An Investigation of Glutathione-Platinum(II) Interactions by Means of the Flow Injection Analysis Using Glassy Carbon Electrode
(MDPI, 2007-07-20)
Glutathione was discovered by M. J. de Rey Pailhade at the end of the 19th century as the substance (hydrogénant le soufre), which was renamed by F.G. Hopkins in 1921. Hopkins first characterised the compound as a dipeptide ...
Study of Interactions between Metallothionein and Cisplatin by using Differential Pulse Voltammetry Brdicka's reaction and Quartz Crystal Microbalance
(MDPI, 2009-03-15)
Treatment strategies for tumour diseases are progressively focusing on personalization of medicine. However, this focus requires methods revealing the early general biological mechanisms, including the formation anti-cancer ...
