Preparation of TiO2 and ZnO thin films by dip-coating method
(Trans Tech Publications Ltd, Durnten-Zurich, 1998)
TiO2 and ZnO thin films were prepared by dip-coating method from TiCl4, and Zn(NO3)(2) precursor solutions, respectively. Basic parameters of the process such as temperature of thermal treatment, heating and cooling regimes, ...
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 ...
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 ...
Electroretinographic evaluation of spectral sensitivity in yellow and silver eels (Anguilla anguilla)
(Cambridge Univ Press, New York, 1998)
Although differences in visual pigments between developmental stages of the European eel are well known, the expected differences in spectral sensitivity have not been demonstrated at the electrophysiological level. In ...
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 ...
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, ...
Kinetic study of stress‐induced luminescence from different tissues
(Photochemistry and Photobiology, 1992)
Abstract— Exponential decay of the stress‐induced luminescence from different tissues was resolved into the first order reaction components and appropriate rate constants were determined from the reaction half‐times. Kinetic ...
Grain growth during sintering of batio3 with lif
(Taylor & Francis Ltd, Abingdon, 1996)
The sintering behavior of BaTiO3 with LiF showed that it was possible to sinter barium titanate at temperatures below 1000 degrees C. Different combinations of the sintering powders were prepared by adding 1 to 5 w% LiF ...
