Photoacoustic and optical properties of zinc-stannate thin films
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Thin films of single-phase zinc-stannate (Zn2SnO4) were grown by rf magnetron sputtering onto glass substrates. Transmission in the visible range was measured allowing determination of the energy gap and thickness of ...
Spectral sensitivity of the dogfish shark (Scyliorhinus canicula)
(Springer, Dordrecht, 2007)
The action spectrum of the electroretinographic (ERG) b-wave and the unmasked late receptor potential (LRP) were measured under a variety of conditions (isolated eyecup, detached retina, b-wave recording in fresh preparations, ...
In vitro multiplication of willow gentian (Gentiana asclepiadea L.) and the production of gentiopicrine and mangiferin
(Phyton - Annales Rei Botanicae, 2006)
A protocol for in vitro propagation of Gentiana asclepiadea was developed. The best multiplication rate was obtained with woody plant medium (WPM) supplemented with 8.9 mu M BAP (6-benzylaminopurine) and 1.1 mu M IAA ...
RF equivalent circuit modeling of surface mounted components for PCB applications
(Emerald Group Publishing Ltd, Bingley, 2010)
Purpose - The appropriate selection of a testing method largely determines the accuracy of a measurement. Parasitic effects associated with test fixture demand a significant consideration in a measurement. The purpose of ...
Microstructural properties of PZT thin films deposited on LaNiO3-coated substrates
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O-3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer Heidelberg, Heidelberg, 2008)
A single p-type crystal of the mineral, pyrite ( FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic ( PA) amplitude and phase spectra were measured using a specially ...
Infrared properties of sintered alpha-MnSe
(Carl Hanser Verlag, Munich, 2006)
Far-infrared reflection spectra of sintered alpha-MnSe were measured at room temperature. The measured spectrum had one pronounced peak in accordance with literature data and group theory estimation and one smaller peak ...
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 ...
Land degradation on barren hills: A case study in northeast Vietnam
(Springer, New York, 2008)
The term "barren hills" has been a keyword for land degradation in the uplands of Vietnam for over a decade. Nevertheless, the "barren" land is still not adequately ecologically characterized. In this work, we analyze land ...
The d-wave in fish and the state of light adaptation
(General Physiology and Biophysics, 2007)
Comparative electroretinographic studies of the d-wave evoked with long duration photo stimuli in dark- and light-adapted fish species (three marine and three freshwater) were performed. At the end of prolonged photo-stimulation ...
