True bugs (Hemiptera, Heteroptera) as psyllid predators (Hemiptera, Psylloidea)
(Pensoft Publ, Sofia, 2013)
Data on natural enemies of psyllids are rare and can usually be found in papers about economically significant species. During an investigation of psyllid fauna in Serbia, natural enemies were investigated, too. True bugs ...
Biochemical Properties of the Fresh and Frozen Black Currants and Juices
(Mary Ann Liebert, Inc, New Rochelle, 2013)
Thirteen black currant varieties (Ribes nigrum L.) cultured in Serbia were characterized for their pomological properties and chemical composition (total phenolics, total anthocyanins, anthocyanin aglycones, sugars, and ...
Testing of self-(in)compatibility in apricot cultivars using fluorescence microscopy
(Acta Scientiarum Polonorum, Hortorum Cultus, 2013)
Self-incompatibility is common in apricot (Prunus armeniaca L.) cultivars of Central Asian and Irano-Caucasian ecogeographical groups, while cultivars of European group are traditionally considered as self-compatible. ...
Testing of self-(in)compatibility in apricot cultivars from European breeding programmes
(Czech Academy Agricultural Sciences, Prague, 2013)
Self-(in)compatibility was tested in 40 new apricot cultivars from European breeding programmes Pollen-tube growth in pistils from laboratory pollinations was analysed using the fluorescence microscopy. Cultivars were ...
Influence of Prolonged Sintering Time on Density and Electrical Properties of Isothermally Sintered Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO center dot ...
The edible mushroom Laetiporus sulphureus as potential source of natural antioxidants
(Taylor & Francis Ltd, Abingdon, 2013)
Hot water extract (LN), partially purified polysaccharides (LP) and hot alkali extracted polysaccharides (LNa) obtained from fruiting bodies of the wild basidiomycete Laetiporus sulphureus were examined for their antioxidant ...
Monitoring of aphid flight activities in seed potato crops in Serbia
(Pensoft Publishers, Sofia, 2013)
Aphid flight activities in seed potato fields have been studied by the yellow water traps. It is a good method for monitoring aphids as vectors of viruses, but this study also showed it is a suitable method for insect-diversity ...
Synthesis, characterization, and thermal behavior of Cu(II) and Zn(II) complexes with (E)-2-[N-(1-pyridin-2-yl-ethylidene)hydrazino]acetic acid (aphaOH). Crystal structure of [Zn-2(aphaO)(2)Cl-2]
(Taylor & Francis Ltd, Abingdon, 2013)
Copper(II) and zinc(II) complexes with the condensation derivative of 2-acetylpyridine and hydrolyzed ethyl hydrazinoacetate were synthesized in a one pot reaction. Crystal structure of the zinc(II) complex was determined ...
A bioassessment of soil nickel genotoxic effect in orchard planted on rehabilitated coalmine overburden
(Academic Press Inc Elsevier Science, San Diego, 2013)
Environmental problems of non-rehabilitated overburden material are present in surrounding of open coal mines worldwide. Ecological restoration of this soil material usually deals with the improvement of its bad physico-chemical ...
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 ...
