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 ...
Spectral and dose dependence of light-induced ion flux responses from maize leaves and their involvement in leaf expansion growth
(Oxford Univ Press, Oxford, 2007)
Two types of segments (intact leaf tissue and isolated mesophyll tissue respectively) were isolated from basal (still growing) and tip (non-growing) maize leaf regions. The leaf segments were exposed to different light ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Self-assembly of Mo6S (8) clusters on the Au(111) surface
(Springer, New York, 2007)
The preferred adsorption sites and the propensity for a self-organised growth of the molybdenum sulfide cluster Mo6S8 on the Au(111) surface are investigated by density-functional band-structure calculations with ...
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, ...
Monitoring of transformations in bentonite after NaOH-TMA treatment
(Elsevier Sci Ltd, Oxford, 2007)
Semi-quantitative methods of X-ray diffraction and FTIR-spectroscopy, accompanied by electron microscopy, X-ray microanalysis and others were used to monitor structural-phase reorganizations occurring in a smectite-gypsum ...
Unique structural and transport properties of molybdenum chalcohalide nanowires
(Amer Physical Soc, College Pk, 2007)
We combine ab initio density functional and quantum transport calculations based on the nonequilibrium Green's function formalism to compare structural, electronic, and transport properties of Mo6S6-xIx nanowires with ...
Spectral and fractal analysis of biosignals and coloured noise
(IEEE, New York, 2007)
The amplitude power spectra and fractal dimensions of surrogate data designed as coloured noise were compared with spectra and FDs of biosignals in order to improve the tools for brain activity analysis. It is interesting ...
Tailoring of morphology and orientation of LaNiO3 films from polymeric precursors
(Elsevier Sci Ltd, Oxford, 2007)
The aim of this work was to prepare lanthanum nickel oxide (LaNiO3, LNO) thin films of different morphology and orientation. The precursor solutions were prepared by a chemical method from citric salts of lanthanum and ...
A novel approach to modeling and simulation of NTC thick-film segmented thermistors for sensor applications
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2007)
This paper describes the design, modeling, simulation, and fabrication of thick-film segmented thermistors. These thermistors were printed on alumina using negative temperature coefficient 3K3 paste, composed of nanometer ...
