Trans- and cis-resveratrol concentration in wines produced in Serbia / Koncentracija trans- i cis-rezveratrola u vinima proizvedenim u Srbiji
(Srpsko hemijsko društvo, Beograd, 2008)
Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the ...
Lead and silver extraction from waste cake from hydrometallurgical zinc production
(Srpsko hemijsko društvo, Beograd, 2008)
This paper presents the experimental results of the extraction of lead and silver from a lead-silver waste cake obtained in the process of hydrometallurgical zinc production. While controlling the pH value, the lead-silver ...
Specific transformations of mineral forms of nitrogen in acid soils / Specifičnosti transformacije mineralnih oblika azota u kiselim zemljištima
(Srpsko hemijsko društvo, Beograd, 2009)
Investigations were performed on soils of different acidity, ranging in the pH interval 4.65-5.80 (in water). Changes of the mineral nitrogen forms in the examined soils were studied by applying short-term incubation ...
Content of heavy metals in Gentiana lutea L. roots and galenic forms / Sadržaj teških metala u korenu i galenskim proizvodima gencijane (Gentiana lutea L.)
(Srpsko hemijsko društvo, Beograd, 2007)
An experimental field for the cultivated production of Gentiana lutea L. was established five years ago at the Suvobor Mountain, Serbia. Soil analysis of this area revealed the occurrence of high pseudo-total (Ni - 1270 ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Srpsko hemijsko društvo, Beograd, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
The effects of some agrotechnical measures on the uptake of nickel by maize plants / Uticaj nekih agrotehničkih mera na usvajanje nikla biljkama kukuruza
(Srpsko hemijsko društvo, Beograd, 2009)
Nickel is a non-essential element in the nutrition of the majority of plant species and can be toxic to plants when its concentration in soils is high. Several soil properties have an effect on the uptake of this heavy ...
The synthesis and preliminary pharmacological evaluation of racemic cis and trans 3-alkylfentanyl analogues / Sinteza i preliminarni farmakološki testovi recemskih cis i trans 3-alkilanaloga fentanila
(Srpsko hemijsko društvo, Beograd, 2004)
A general, five step method for the synthesis of 3-alkylfentanyl analogues (i.e., cis and trans 3-alkyl-4-anilidopiperidines 6.1–6.6) has been developed. The starting N-phenethyl- 4-piperidone 1 was first converted into ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Srpsko hemijsko društvo, Beograd, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
Antioxidant activities of the constituents of Picris echoides / Sastav i antioksidativna aktivnost Picris echoides
(Srpsko hemijsko društvo, Beograd, 2002)
Some flavonoids with antioxidant properties from the aerial parts of the plant species Picris echoides (family Asteraceae) were identified. Upon chromatography, the ethyl acetate extract afforded flavonoids, such as flavone ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder. I. Modeling of a representative powder particle
(Srpsko hemijsko društvo, Beograd, 2003)
One of the most important properties of copper powder is its flowability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
