Vertical Distribution of Air Temperatures in Heated Dwelling Rooms
(FINVAC - The Finnish Association of HVAC, 2007-07-13)
The paper presents an experimental and theoretic research on one of factors influencing the indoor climate in dwelling rooms heated by heating systems, the vertical distribution of temperatures. The paper summarizes results ...
Utilizing of square wave voltammetry to detect flavonoids in the presence of human urine
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 ...
Shapes of Differential Pulse Voltammograms and Level of Metallothionein at Different Animal Species
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 ...
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 ...
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 ...
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.
An Investigation of Glutathione-Platinum(II) Interactions by Means of the Flow Injection Analysis Using Glassy Carbon Electrode
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 ...
Multifunction RF Filters Using OTA
In this paper the procedure of RF filter design using two active elements OTA is shown. The general method of filter design using OTA amplifiers, when the fully connected feedback network was designed around the two OTA ...
