Feeding habits of huchen Hucho hucho (Salmonidae) fry in the River Tresnjica, Yugoslavia
(Taylor & Francis Ltd, Abingdon, 1998)
About 10 000 huchen larvae, obtained by artificial spawning, were introduced on 28 May 1995 into the River Tresnjica, a tributary to the River Drina, using procedures applied routinely by local fishing associations. During ...
Study of photochemical reactions of coniferyl alcohol. II. Comparative structural study of a photochemical and enzymatic polymer of coniferyl alcohol
(American Society for Photobiology, 1998)
The structure of the polymer synthesized by UV irradiation of coniferyl alcohol was studied, using UV-visible, Raman, IR, LH-NMR and C-13-NMR spectroscopy. The photochemical polymer was compared with the structure of the ...
Spontaneous ultraweak, bioluminescence in plants: Origin, mechanisms and properties
(R and D print, 1998)
An analysis of theoretical knowledge and experimental results of ultraweak luminescence (UWL) is provided. The role of excited state of molecules and free radicals, formed in various biochemical reactions, in UWL is ...
The dependence of the work function of rare earth metals on their electron structure
(Elsevier Sci Ltd, Oxford, 1996)
The work function primarily depends on the electron structure of the analysed material. Having in mind the importance of rare earth metals in advanced electronics, in this paper the dependence of the work function of rare ...
Age, growth, sexual maturity and diet of the Mediterranean barbel (Barbus peloponnesius petenyi) in the River Gradac (West Serbia, Yugoslavia)
(Czech Academy of Sciences, 1996)
Mediterranean barbel Barbus peloponnesius petenyi from the River Gradac were studied during the period September 1985 - July 1993 with the aim to determine their growth and feeding habits. The age estimated from scales ...
Free radical involvement in the generation of trans-root potential
(Wiley, Hoboken, 1998)
The identity of the naturally occurring compounds that accept electrons from plasma membrane-bound redox systems in vivo is obscure. We analysed the effect of ascorbate, oxygen, iron, as well as their free radical forms, ...
Influence of spinel phase composition on ZnO varistors properties
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
The method of directed synthesis of the constituent phases (DSCP) was applied to investigate the influence of spinel phase composition on characteristics of ZnO varistors. Six varistor mixtures differing only in chemical ...
Electrophysiological and spectral properties of second-order retinal neurons in the eel
(Elsevier Science Inc, New York, 1998)
Several classes of second-order neurons have been electrophysiologically explored in immature European eels (Anguilla anguilla) from two distant and ecologically different localities tin Russia and Yugoslavia). The majority ...
Effects of the air pollutant SO2 on leaves: Inhibition of sulfite oxidation in the apoplast by ascorbate and of apoplastic peroxidase by sulfite
(American Society of Plant Biologists, 1992)
After SO2 has entered leaves of spinach (Spinacia oleracea) through open stomata and been hydrated in the aqueous phase of cell walls, the sulfite formed can be oxidized to sulfate by an apoplastic peroxidase that is ...
A study of lignin formation at the molecular level by scanning tunneling microscopy
(Biophysical Journal, 1994)
A scanning tunneling microscope (STM) was used to observe the temporal formation and organization of dehydrogenative polymer (DHP) synthesized from coniferyl alcohol. The images obtained elucidate this structure for the ...
