On strain-rate sensitivity and size effect of brittle solids: transition from cooperative phenomena to microcrack nucleation
(Springer Nature, 2013)
An idealized brittle microscale system is subjected to dynamic uniaxial tension in the medium-tohigh
strain-rate range (˙ε ∈ [100 s−1, 1×107 s−1]) to investigate its mechanical response under constrained
spatial and ...
Activities of antioxidant systems during germination of Chenopodium rubrum seeds
(Kluwer Academic Publishers, 2003)
The activities of superoxide-dismutase (SOD), catalase (CAT) and peroxidase (POD), and concentrations of glutathione and ascorbate have been studied during the first stages of germination in Chenopodium rubrum L. seeds. ...
Effect of darkness on growth and flowering of Chenopodium rubrum and C. murale plants in vitro
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2003)
Chenopodium rubrum, a short-day plant, and C. murale, a long-day plant, were grown in vitro in continuous darkness. Control C. rubrum plants exposed to continuous darkness for 15 d at cotyledonary phase, did not flower, ...
Structural and Electrical Properties of Ti Doped alpha-Fe2O3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
In this work we have analyzed the effects of Ti doping on structural and electrical properties of alpha-Fe2O3. When the amount of added Ti (5 wt.% TiO2) was within the solubility degree and XRD, SEM and EDS analysis revealed ...
Electrical properties of antimony doped barium titanate ceramics
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Antimony doped barium titanate powders were synthesized by polymeric precursors method based on modified Pechini process. Obtained powders were pressed and sintered at 1300 degrees C for 8 h. XRD analysis showed the formation ...
Properties of MnZn ferrites prepared by powder injection molding technology
(Elsevier Science Bv, Amsterdam, 2010)
In this work, manganese zinc ferrite components were manufactured by powder injection molding-PIM technology. A fine powder consisting of Mn1-xZnxFe2O4 with small addition of hematite alpha-Fe2O3 as used in mass ferrite ...
Fluorescence-Detected Linear Dichroism of Wood Cell Walls in Juvenile Serbian Spruce: Estimation of Compression Wood Severity
(Cambridge Univ Press, New York, 2016)
Fluorescence-detected linear dichroism (FDLD) microscopy provides observation of structural order in a microscopic sample and its expression in numerical terms, enabling both quantitative and qualitative comparison among ...
In vitro anti-hydroxyl radical activity of the fructooligosaccharides 1-kestose and nystose using spectroscopic and computational approaches
(Wiley, Hoboken, 2014)
Fructooligosaccharides (FOS) are bioactive oligosaccharide fructans with beneficial health effects. Anti-hydroxyl radical activity is an important factor in the description of antioxidant capacity of any natural product. ...
Fly ash as the potential raw mixture component for portland cement clinker synthesis
(Springer, Dordrecht, 2009)
This paper presents the results of investigation of properties of fly ash from four major thermal power plants in Serbia. Chemical, mineralogical and thermal characterization of fly ash has been performed in order to ...
Metabarcoding Approach for Evaluation of Bacterial Diversity in Soft Rotting Potato Tubers and Corresponding Geocaulospheres
(Springer, 2022)
Plant pathogenic bacteria from the genera Pectobacterium and Dickeya in association with potato cause blackleg and tuber soft rot disease. A metabarcoding was
used to analyze the microbial communities of soft-rotted ...
