Mortality of red mullet (mullus barbatus linnaeus, 1758) on the Montenegrin shelf (south Adriatic)
(Srpsko biološko društvo, Beograd, i dr., 2009)
Red mullet, Mullus barbatus Linnaeus, 1758, is an economically very important species in trawl fisheries in the Adriatic Sea. Material for analysis was collected from October 2002 until May 2004 with a bottom trawl net ...
Heavy metals in the leaves of tree species paulownia elongata syhu in the region of the city of Belgrade
(Taylor & Francis Ltd, Abingdon, 2009)
Based on the analysis of the heavy metal content (Zn, Fe, Pb, Cu, Ni, Cr Mn, Cd, As, Hg) in leaves of the trees growing in the urban part of the city of Belgrade, wider city area and rural area it may be noted that the ...
Deconvolution of lignin fluorescence spectra: A contribution to the comparative structural studies of lignins
(Maik Nauka/Interperiodica/Springer, New York, 2007)
In this work, we deconvoluted the fluorescence spectra of lignin and a lignin model compound using a combination of one symmetric ( Gaussian) and the most appropriate number of asymmetric (Log-normal) models. We aimed to ...
Optical far infrared properties of FeS2
(National Institute of Optoelectronics, 2010)
In this paper are presented the far-infrared reflectivity spectra for a cleaved FeS2 sample measured at roam temperature and at 77 K.
Concentrations of heavy metals in soil and leaves of plant species Paulownia elongata SYHu and Paulownia fortunei Hemsl
(Academic Journals, Victoria Island, 2009)
This paper sums up the results of the research on heavy metals contents (Pb, Ni, Fe, Zn and Mn) in soil and leaves of the plant species, Paulownia elongata S.Y. Hu and Paulownia fortunei Hemsl. at the plantation established ...
Flavonoids from the aerial parts of Onobrychis montana subsp scardica
(Srpsko hemijsko društvo, Beograd, 2008)
Rutin (1, main constituent) and two flavone C-glycosides, vitexin (2) and vitexin 2 ''-O-alpha-rhamnopyranoside (3) were isolated from the aerial parts of Onobrychis montana subsp. scardica. They were identified by H-1-NMR, ...
Levels of plant cell wall structural organization revealed by atomic force microscopy
(Wiley, Hoboken, 2008)
We used an atomic force microscope to image cell wall isolated from needles of Serbian spruce tree and that synthesized from cell wall components. We also observed the structure of lignin model polymer (DHP), as a best ...
Influence of substrate orientation on the morphologyand orientation of LaNiO3 thin films
(Wiley, Hoboken, 2008)
LaNiO3 thin films were successfully prepared by a chemical method from citrate precursors. The LNO precursor solution was spin-coated onto Si (100) and Si (111) substrates. To obtain epitaxial or highly oriented films, the ...
Structure and Properties of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(Taylor & Francis Ltd, Abingdon, 2008)
Bi4Ti4O15 [BBT], a member of Aurivillius bismuth-based layer-structure perovskites, was prepared from stoichiometric amounts of BaTiO3 [BT] and Bi4Ti3O12 [BIT] obtained via mechanochemical synthesis. Mechanochemical synthesis ...
Biochemical characterization of a sphingomonad isolate from the ascocarp of white truffle (tuber magnatum pico)
(Srpsko biološko društvo, Beograd, i dr., 2011)
Available information on bacteria that influence the economically important white truffle (Tuber magnatum Pico) life cycle is scarce. From the ascocarp of white truffle we isolated a strain TMG 022C, capable for growth in ...
