(Taylor & Francis Inc, Philadelphia, 2004)
Chemical analysis and antimicrobial activity of essential oil isolated by steam distillation from Ambrosia artemisiifolia L., Asteraceae dried flowering herb were performed. Principal constituents were germacrene D (24.1%), ...
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 ...
The synthesis and pharmacological evaluation of (±)-2, 3- seco-fentanyl analogues / Sinteza i farmakološko ispitivanje (±)-2,3-seco-analoga fentanila
(Srpsko hemijsko društvo, Beograd, 2004)
An efficient, five-step synthetic approach to various acyclic 1,3-diamines has been developed and applied to the preparation of a novel class of open-chained fentanyl analogues. The acyclic derivatives 5.1–5.5 (all new ...
Investigation of kernel oils of Quercus robur and Quercus cerris
(Springer, New York, 2004)
The kemel oils of Quercus robur and Quercus cerris were obtained by Soxhlet extraction using petroleum ether. Oil yields were found to be 5.2-5.6% and 4.3-4.8% for Q. robur and Q. cerris kemel, respectively (expressed in ...
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 ...
Alterations in liver and kidneys of chickens fed with high levels of sodium selenite or selenized yeast / Promene na jetri i bubrezima pilića hranjenih visokim nivoima natrijum selenita ili seleniziranog kvasca
