Glass fibre reinforced cement based composite: fatigue and fracture parameters
This paper introduces the basic fracture mechanics parameters of advanced building material - glass fibres reinforced cement based composite and its fracture and fatigue behaviour is investigated. To this aim three-point ...
Crack propagation in the vicinity of the interface in layered materials
(University of West Bohemia, 2009-01-04)
Paper deals with the problem of crack propagation in the vicinity of the interface in layered materials. Layered materials are often used in practice, primarily because of their better mechanical properties in comparison ...
Fracture mechanics parameters of multilayer pipes
(University of West Bohemia, 2007-10-19)
Multilayer pipes consisting of different materials are frequently used in praxis because of partial improvement of the properties of pipe systems. To estimate lifetime of these pipes the basic fracture parameters have to ...
A Novel Current-Mode SIMO Type Universal Filter Using CFTAs
(Hikari Ltd., 2009-02-01)
In this paper a new active element for the realization of current-mode analog blocks Current Follower Transconductance Amplifier (CFTA) is presented. The element is a combination of the Current Follower (CF) and the Balanced ...
Lactoferrin Isolation Using Monolithic Column Coupled with Spectrometric or Micro-Amperometric Detector
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 ...
Spectrometric and Voltammetric Analysis of Urease: Nickel Nanoelectrode as an Electrochemical Sensor
Urease is the enzyme catalyzing the hydrolysis of urea into carbon dioxide and ammonia. This enzyme is substrate-specific, which means that the enzyme catalyzes the hydrolysis of urea only. This feature is a basic diagnostic ...
Amperometric Sensor for Detection of Chloride Ions
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 ...
Study of Interactions between Metallothionein and Cisplatin by using Differential Pulse Voltammetry Brdicka's reaction and Quartz Crystal Microbalance
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 ...
Detailed balance in reaction kinetics - consequence of mass conservation?
Detailed balance condition for triangular isomerisation mechanism is derived from the more general permanence of atoms, consequently, it should be viewed as a special equilibrium result of mass conservation.
New Hydrodynamic Electrochemical Arrangement for Cadmium Ions Detection Using Thick-Film Chemical Sensor Electrodes
Miniaturization and integration of chemical devices into modules that are dimensionally comparable with electronic chips (Lab on Chip) is nowadays developing worldwide. The aim of our work was to suggest and optimize the ...
