A Comparative Assessment of the Potential of Polysaccharide Production and Intracellular Sugar Composition within Lingzhi or Reishi Medicinal Mushroom, Ganoderma lucidum (W.Curt.:Fr.)P. Karst. (Aphyllophoromycetideae)
(Begell House Inc, Danbury, 2011)
Ganoderma lucidum is a well-known medicinal mushroom species in which polysaccharides are one of the major sources of biological activity. The species was considered as a species-complex due to significant variations in ...
Defect induced variation in vibrational and optoelectronic properties of nanocrystalline ZnO powders
(Amer Inst Physics, Melville, 2011)
Structural disorder of ZnO nanopowders with mean crystallite size down to 15 nm, produced by mechanical activation in high energy mills, has been analyzed by x-ray diffraction and Raman spectroscopy. The influence of such ...
Structural organisation of the wood polymers in the wood fibre structure
(China Light Industry Press, Beijing, 2011)
The organisation of the major polymers in the wood fibre structure has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, the structure providing ...
Antioxidant activity of small grain cereals caused by phenolics and lipid soluble antioxidants
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
In this study, the content of soluble, free forms of phenolic compounds (total phenolics, flavonoids, PVPP (polyvinylpolypyrrolidone) bound phenolics, proanthocyanidins and phenolic acids), as well as the content of ...
Hydrogen storage properties of MgH2 mechanically milled with alpha and beta SiC
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
To understand the influence of various crystallographic phases on hydrogen storage properties, ball milling of MgH2 with hexagonal (alpha) and cubic (beta) SiC have been performed. Structural characterization of all samples ...
Bio-activities of extracts from some axenically farmed and naturally grown bryophytes
(Academic Journals, Victoria Island, 2011)
The antifungal activity of dimethyl sulfoxide (DMSO) extracts of three bryophyte species, two mosses (Atrichum undulatum (Hedw.) P. Beauv., Physcomitrella patens (Hedw.) Bruch and Schimp) and a liverwort (Marchantia ...
Insight into Danube sturgeon life history: trace element assessment in pectoral fin rays
(Springer, New York, 2011)
Sturgeon populations in the Danube River have experienced severe decline during the last several decades, mostly due to the poorly regulated fishery, river fragmentation and water pollution. This study focuses on gaining ...
Independent complexity patterns in single neuron activity induced by static magnetic field
(Elsevier Ireland Ltd, Clare, 2011)
We applied a combination of fractal analysis and Independent Component Analysis (ICA) method to detect the sources of fractal complexity in snail Br neuron activity induced by static magnetic field of 2.7 mT. The fractal ...
Development of fly ash-based geopolymer microstructure at room temperature
(Novpress Sro, Brno, 2011)
The development of geopolymers, as an alternative to traditional cement, by alkali activation of fly ash is a research topic in the scientific community. Many authors have agreed that there is a strong link between mechanical ...
Influence of the ratio between Ni and BaCe0 9Y0 1O3-delta on microstructural and electrical properties of proton conducting Ni-BaCe0 Y-9(0) O-1(3-delta) anodes
(Elsevier Science Sa, Lausanne, 2011)
Cermet anode substrates Ni-BaCe0 9Y0 1O3-delta (Ni-BCY10) with varied ratios between Ni and BCY10 were prepared BCY10 powders were prepared by the citrate-nitrate auto-combustion method and anode substrates were prepared ...
