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%; ...

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 ...
