Fractal analysis of artificial and cerebellar signals at sampling frequencies of 32-4096 Hz
(Serbian-Hungarian Joint Symposium on Intelligent Systems, 2005)
The aim of this study was to investigate the effects of varying sampling frequencies on fractal analysis of artificial and cerebellar signals. Applying Higuchi's algorithm, we calculated fractal dimension (FD) values of ...
Somatic embryogenesis in Chenopodium rubrum and Chenopodium murale in vitro
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2005)
In order to establish an efficient system for in vitro plant regeneration of a short day plant Chenopodium rubrum L. and a long day plant Chenopodium murale L., optimum culture conditions for somatic embryogenesis were ...
Changes in Chenopodium rubrum seeds with aging
(New York Acad Sciences, New York, 2005)
We studied antioxidative system, germination, growth, and flowering in vitro in Chenopodium rubrum seeds of different ages. Peroxidase, superoxide dismutase, and catalase activity, as well as glutathione status, were ...
New insights into the structural organization of the plant polymer lignin
(New York Acad Sciences, New York, 2005)
The organizational features of lignin structure and the mechanism of its synthesis have significant implications for the response of the plant to stress. It was unknown whether the enzymic formation of lignin in the cell ...
Microstructural characterization of mechanically activated ZnO-Cr2O3 system
(Elsevier Sci Ltd, Oxford, 2005)
An equimolar mixtures of starting ZnO and Cr2O3 powders were mechanically activated by grinding using a planetary ball mill for various periods of time (40-320min). Formation of nanocrystalline ZnCr2O4 as normal spine] ...
