Detailed balance in reaction kinetics - consequence of mass conservation?
(Springer-Verlag, 2007-01-01)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. -
Aggregation behavior of novel hyaluronan derivatives-a fluorescence probe study
(Springer-Verlag, 2008-11-01)Aggregation properties of hydrophobized hyaluronan (hHA) in different molecular weights and degree of substitution were studied by pyrene and perylene fluorescence method. The critical aggregation concentration (cac) was ... -
Fluoride Anion Binding by Natural Lignite (South Moravian Deposit of Vienna Basin)
(Springer-Verlag, 2009-01-01)Natural lignite from South Moravia was tested for the sorption of fluoride anion in concentration range from 0.05 to 0.8 mmol/l. The lignite removes majority of fluorides and only about 13% of sorption is reversible upon ... -

(University of Veterinary and Pharmaceutical Sciences in Brno, 2009-12-15)Synthesis and characterization of biodegradable hydrogels based on collagen modified by addition of synthetic biodegradable copolymer intended for preparation of porous scaffolds for mesenchymal stem cells used for possible ... -
Macroscopic derivation of the kinetic mass-action law
(Springer-Verlag, 2010-01-01)Using several reaction examples with experimentally determined rate equations, traditional mass action rate equations are shown to be simplified forms of polynomial approximation to a general rate function derived by ... -
Healing of Large Segmental Bone Defect after Implantation of Autogenous Cancellous Bone Graft in Comparison to Hydroxyapatite and 0.5% Collagen Scaffold Combined with Mesenchymal Stem Cells
(University of Veterinary and Pharmaceutical Sciences in Brno, 2010-04-06)At present, attention is focused on research into possibilities of healing large bone defects by the method of mini-invasive osteosynthesis, using implantation of biomaterials and mesenchymal stem cells (MSCs). This study ... -
The Effect of Soybean-Derived Phytoestrogens on Concentrations of Plasma Isoflavones, 15-keto-13,14-dihydroprostaglandin F2alfa and Progesterone in Dairy Cows
(University of Veterinary and Pharmaceutical Sciences in Brno, 2010-09-19)The objective of the study was to determine the effect of soybean-derived phytoestrogens and their metabolites on the activity of sex hormones during the oestrous cycle in multiparous lactating dairy cows. The experiment ... -
Atomic force microscopy analysis of nanoparticles in non-ideal conditions
(Springer Open, 2011-08-30)Nanoparticles are often measured using atomic force microscopy or other scanning probe microscopy methods. For isolated nanoparticles on flat substrates, this is a relatively easy task. However, in real situations, we often ... -
Comparative Study of Binding Behaviour of Cu(II) with Humic Acid and Simple Organic Compounds by Ultrasound Spectrometry
(Bentham Science Publihers, 2011-11-12)Several simple organic (hydroxy)acids as models of principal functional moieties of humic acids and the copper ion as a model ion were used to investigate the metal-humic interactions. The quantum chemical calculations ... -
Complexation of Copper(II) with Humic Acids Studied by Ultrasound Spectrometry
(Hindawi Publishing Corporation, 2012-05-14)Copper biogeochemistry is controlled by bonding to natural organic matter. The soluble forms of bonded copper can be more biologically active due to the higher migration in environmental systems and instability of some ... -
Vacuum Deposited Diphenyl-Diketo-Pyrrolopyrroles Structures with Photoelectrical Application
(IOP Publishing Ltd, 2014-05-15)ITO|composite|Al structures with active DPP-C60 composite films (ratio 60:40 mass %) of about 100 nm thicknesses were prepared. The surface morphology of the films was studied by SEM imaging, which revealed uniform films ... -
Aerosol Flow Homogenization in the Spray Polyphenylene Vinylene Thin Film Deposition
(IOP Publishing, 2014-05-15)Two different spray deposition (SD) techniques were compared on polyvinylene (MDMO-PPV) used as a model material. SD and homogenized (h-SD) techniques were compared. Films of about 1 micron thickness were prepared by SD ... -
