Effect of long-term cyanide exposure on cyanide-sensitive respiration and phosphate metabolism in the fungus phycomyces blakesleeanus
(Srpsko biološko društvo, Beograd, i dr., 2014)
The effects of long-term exposure (5 h) of Phycomyces blakesleeanus mycelium to 5 mM KCN on respiration and phosphate metabolites were tested. Exposure to cyanide, antimycin A and azide lead to a decrease in the activity ...
Selection and rapd analysis of pseudomonas ssp. Isolates able to improve biological viability of potato seed tubers
(Društvo genetičara Srbije, Beograd, 2013)
Indoleacetic acid (IAA) producing Pseudomonas isolates from the rhizosphere of maize (Q4 and Q20), alfalfa (Q1 and Q16) and wild red clover (B25) were selected for the investigation of their effect on the biological vitality ...
The sorption of inorganic arsenic on modified sepiolite: the effect of hydrated iron(III) oxide
(Srpsko hemijsko društvo, Beograd, 2014)
The sorption of inorganic arsenic species, As(III) and As(V), from water by sepiolite modified with hydrated iron(III) oxide was investigated at 25 degrees C through batch studies. The influence of the initial pH value, ...
The geometric morphometrics and condition of Pontic shad, Alosa immaculata (Pisces: Clupeidae) migrants to the Danube River
(Taylor & Francis Ltd, Abingdon, 2013)
Anadromous fish could have intraspecific groups with different life histories; identification of these is very important for management and conservation. Geometric morphometrics represents a quick and cost-effective method ...
The electrical properties of chemically obtained barium titanate improved by attrition milling
(Springer, New York, 2013)
Barium titanate ceramics were prepared using the nanopowder resulting from a polymeric precursor method, a type of modified Pechini process. The obtained nanopowder was observed to agglomerate and in order to de-agglomerate ...
Estimation of meristemoid complexity during Tacitus bellus in vitro shoot organogenesis by 2D fractal analysis
(Univerzitet u Beogradu - Biološki fakultet - Institut za botaniku i botaničku baštu "Jevremovac", Beograd, 2015)
This study considered the analysis of 2D fractal characteristics of cell populations that participate in meristemoid formation during the process of de novo shoot organogenesis in Tacitus bellus leaf explant culture. ...
Characterization of the Alkoxide-based Sol-gel Derived La9.33Si6O26 Powder and Ceramic
(Slovensko Kemijsko Drustvo, Ljubljana, 2014)
In this study, we report on the acid-catalysed synthesis of La9.33Si6O26 from lanthanum nitrate or acetate and silicon ethoxide (TEOS) in the ethanol solvent, upon the transition from liquid to amorphous and crystalline ...
The modification of structural and optical properties of nano- and submicron ZnO powders by variation of solvothermal syntheses conditions
(Springer, Dordrecht, 2014)
Nano- (30-60 nm) and submicron (100-350 nm) ZnO particles were synthesized using solvothermal method at 200 degrees C from an ethanolic solution of zinc acetate dihydrate, applying different reaction conditions, i.e., pH ...
Soybean hull peroxidase immobilization on macroporous glycidyl methacrylates with different surface characteristics
(Springer, New York, 2014)
Soybean hull peroxidase (SHP, E.C. 1.11.1.7) was immobilized by a glutaraldehyde and periodate method onto series of macroporous copolymers of glycidyl methacrylate (GMA) and ethylene glycol dimethacrylate (EGDMA), ...
Decomposition of Complex Fluorescence Spectra Containing Components with Close Emission Maxima Positions and Similar Quantum Yields. Application to Fluorescence Spectra of Proteins
(Springer/Plenum Publishers, New York, 2013)
Despite of widely application of multivariate analysis in chemometrics, problem of resolving closely positioned components in the fluorescence spectra remained unsolved, thus limiting the usage of fluorescence spectroscopy ...
