Analysis of early-stage sintering mechanisms of mechanically activated BaTiO3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Barium-titanate powder was mechanically activated in a planetary-ball mill for 60 and 120 minutes. Non-isothermal sintering of non-activated and activated powder samples was investigated using a dilatometer in the temperature ...

The original and comprehensive research of Yakov Rich Frenkel in physics and physical chemistry of condensed states, nuclear physics, electrodynamics, science of sintering has significantly contributed to the development ...
Alterations in amount of chlorophyll as indicator of resistance for Chenopodium album L. and Amaranthus retroflexus L. to atrazine
(Springer Heidelberg, Heidelberg, 2006)
Resistance in weeds, as a natural phenomenon or caused by herbicide application, is a major challenge for science and agricultural production. Nevertheless, a small number of plants is naturally resistant or has developed ...
Comparison of the swelling kinetics of a partially neutralized poly(acrylic acid) hydrogel in distilled water and physiological solution / Poređenje kinetike bubrenja hidrogela delimično neutralisane poli(akrilne) kiseline u destilovanoj vodi i fiziološkom rastvoru
(Srpsko hemijsko društvo, Beograd, 2007)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in distilled water and physiological solution at temperatures ranging from 20 to 40 ºC were determined. The possibility of applying both the ...
Variability of Essential Oil Composition of Cultivated Feverfew (Tanacetum parthenium (L.) Schultz Bip.) Populations
(Journal of Essential Oil Research, 2009)
The differences in essential oil composition, based upon GC and GC/MS analysis, were studied in four cultivated populations of Feverfew (Tanacetum parthenium (L.) Schulz Bip.). The yield of oil ranged from 0.23% to 0.36%; ...

(Springer, Dordrecht, 2006)
Six aphid species new for Italy were caught by suction trap in the Friuli-Venezia Giulia region, Italy. They are: Chaetosiphon chaetosiphon (Nevsky), Illinoia morrisoni (Swain), Myzodium modestum (Hottes), Pseudacaudella ...
Systematic remarks on eriophyoid mites from the subfamily Phytoptinae Murray, 1877 (Acari: Eriophyoidea: Phytoptidae)
(Magnolia Press, Auckland, 2009)
In this paper a critical analysis of the subfamily Phytoptinae is undertaken. Five new combinations are stated: Oziella nilotica (Abou-Awad, 1981) comb. n. (from Phytopus Dujardin, 1851); O. gigantica (Mohanasundaram, 1981) ...
The Effect of Dietary Selenium Source and Level on Hen Production and Egg Selenium Concentration
(Humana Press Inc, Totowa, 2009)
A 16-week experiment was conducted to compare effects of various levels of sodium selenite (SS) and Se-enriched yeast (SY), on the whole-egg Se content and hen's productivity. One hundred Shaver 579 hens, 27 weeks old, ...
The influence of zeolite type added to cigarette blend on the changes of pyrolitic temperatures
(Savez hemijskih inženjera, Beograd, 2009)
Reduction of harmful tobacco smoke compounds, such as nitrosamines and polycyclic aromatic hydrocarbons (PAHs) could be particularly controlled by adjusting the cigarette pyrolitic conditions. One possible way to do that ...
Partial root drying irrigation technique: Practical application of drought stress signaling mechanism in plants / Tehnika delimičnog sušenja korenova - praktična primena signalnih mehanizama suše kod biljaka
(Srpsko biološko društvo, Beograd, i dr., 2009)
Partial root-zone drying (PRD) technique, a novel approach to watering crops, was developed on the basis of knowledge of root-to-shoot signaling in drying soil. The aim of the present paper was to investigate the effects ...
