Isopiestic determination of the osmotic and activity coefficients of the {yKNO(3) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and ...
Lead concentrations and isotope ratios in urban tree leaves
(Elsevier, Amsterdam, 2013)
Variation in stable lead isotopic composition has been recognized as a suitable indicator for source identification of Pb contamination in the environment. Some deciduous tree leaves have been reported as useful biomonitors ...
SFE as a superior technique for isolation of extracts with strong antibacterial activities from lichen Usnea barbata L.
(Elsevier Science Bv, Amsterdam, 2012)
The number of cases of fatal infections in humans and animals caused by multiresistant and panresistant bacterial strains has been dramatically increased over the past 10 years on almost every continent. Therefore, ...
Inhibition of myeloperoxidase and antioxidative activity of Gentiana lutea extracts
(Elsevier, Amsterdam, 2012)
The aim of this study was to investigate the inhibitory activity of Gentiana lutea extracts on the enzyme myeloperoxidase (MPO), as well as the antioxidant activity of these extracts and their correlation with the total ...

Encapsulation of thyme (Thymus serpyllum L.) aqueous extract in calcium alginate beads
(Wiley, Hoboken, 2012)
BACKGROUND: Encapsulation of Thymus serpyllum L. aqueous extract within calcium alginate beads was studied in order to produce dosage formulations containing polyphenolic compounds. Electrostatic extrusion was applied for ...
Multivariate evaluation of the correlation between retention data and molecular descriptors of antiepileptic hydantoin analogs
(Wiley-Blackwell, Malden, 2012)
Molecular properties relevant to pharmacokinetics of two sets of newly synthesized hydantoin derivatives based on two well-known drugs (Nirvanol and Phenytoin) were studied. Properties under consideration were either ...
Biointerface dynamics - Multi scale modeling considerations
(Elsevier, Amsterdam, 2015)
Irreversible nature of matrix structural changes around the immobilized cell aggregates caused by cell expansion is considered within the Ca-alginate microbeads. It is related to various effects: (1) cell-bulk surface ...
Structural and optical characteristics of silver/poly(N-vinyl-2-pyrrolidone) nanosystems synthesized by gamma-irradiation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Silver nanoparticles (AgNPs) were synthesized in situ by gamma-irradiation using poly(N-vinyl-2-pyrrolidone) (PVP) as a capping agent. The concentration, molecular weight and the structure (crosslinked and interpenetrated ...
Some practical aspects of nonlinear frequency response method for investigation of adsorption equilibrium and kinetics
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Some practical aspects regarding application of the nonlinear frequency response (NFR) method for investigation of gas adsorption: choice of the optimal mass of the adsorbent, frequency range and input amplitude, are studied ...
