Chemical Composition and Antimicrobial Activity of the Essential Oils of Micromeria thymifolia (Scop.) Fritsch., M. dalmatica Benth., and Satureja cuneifolia Ten. and Its Secretory Elements
(Taylor & Francis Inc, Philadelphia, 2010)
Light yellowish, pleasant-smelling essential oils were obtained in 0.3%, 1.3%, and 0.8% yields from the aerial parts of S. cuneifolia Ten., M. thymifolia (Scop.) Fritsch., and M. dalmatica Benth, respectively. Thirty-four ...
Identification and spectra-structure determination of soil minerals: Raman study supported by IR spectroscopy and X-ray powder diffraction
(Wiley, Hoboken, 2010)
Raman and IR spectroscopy were used for the characterization of several minerals in morphologically similar vertisol sequences from Kizevak (Serbia). It helped us to establish the surface layer transition going from calcic ...
The investigation of phenol removal from aqueous solutions by zeolites as solid adsorbents
(Elsevier, Amsterdam, 2010)
This work reports results on phenol adsorption from aqueous solutions on synthetic BEA (beta) and MFI (ZSM-5) zeolites, studied by heat-flow microcalorimetry. For the sake of comparison, the adsorption was performed on ...
Plant-eriophyoid mite interactions: specific and unspecific morphological alterations. Part II
(Springer, Dordrecht, 2010)
The paper presents recent advances related to both specific and unspecific morphological alterations of plant organs caused by eriophyoid mites. Based on old and new case studies, the diversity of plant malformations, such ...
Impact of irrigation with treated low quality water on the heavy metal contents of a soil-crop system in Serbia
(Elsevier, Amsterdam, 2010)
Water availability for irrigation is a limiting factor for agriculture in Mediterranean countries. An upcoming strategy for increasing water supply is to use treated wastewater for irrigation. A principal drawback of ...
Evaluation of different methods for determining growing degree-day thresholds in apricot cultivars
(Springer, New York, 2010)
The aim of this study was to examine different methods for determining growing degree-day (GDD) threshold temperatures for two phenological stages (full bloom and harvest) and select the optimal thresholds for a greater ...
Pyrohydrolytic determination of fluorine in coal: A chemometric approach
(Elsevier Science Bv, Amsterdam, 2010)
Corrosion effects in thermal power plants and environmental impact cause an increase in demand for fluorine analysis in coal. Solid sample decomposition, organic and inorganic fluorine compounds, volatility of fluorine ...
Quantification of transfer of U-238, Ra-226, Th-232, K-40 and Cs-137 in mosses of a semi-natural ecosystem
(Elsevier Sci Ltd, Oxford, 2010)
There is a lack of appropriate data on transfer of some radionuclides on many terrestrial biota groups. To expand the available data concentration ratios of U-238, Ra-226, Th-232, K-40 and Cs-137 in mosses are presented ...
Impedance Response and Dielectric Relaxation in Liquid-Phase Sintered Zn2SnO4-SnO2 Ceramics
(Springer, New York, 2010)
Impedance/admittance and dielectric spectroscopy were used to investigate the effect of temperature on the electrical response of liquid-phase sintered Zn2SnO4-SnO2 ceramics. The measurements were performed over a wide ...
Influence of Rare-Earth Dopants on Barium Titanate Ceramics Microstructure and Corresponding Electrical Properties
(Wiley-Blackwell Publishing, Inc, Malden, 2010)
In this article, ytterbium and erbium oxides are used as doping materials for barium titanate (BaTiO(3)) materials. The amphoteric behavior of these rare-earth ions leads to the increase of dielectric permittivity and ...
