Infrared properties of sintered α-MnSe
(Carl Hanser Verlag, 2006)
Far-infrared reflection spectra of sintered α-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 resulting ...
Morphological characteristics of mechanically processed ZnO and MnO2 powder mixtures
(Elsevier Science Sa, Lausanne, 2009)
The evolution of structural-morphological characteristics of ZnO + 1 wt.% MnO2 and ZnO + 10 wt.% MnO2 samples during prolonged mechanical treatment (MT) was investigated by X-ray, AFM, LPS, SEM and IR methods. Changes in ...
Characterization of enzymatically synthesized diferulate
(New York Acad Sciences, New York, 2005)
Horseradish peroxidase was used to synthesize diferulates by a procedure in which ethyl ferulate was used as substrate. Four different forms were obtained, of which two dominant were the 5-5' and 8-5' diferulate. Fluorescence ...
Does high bicarbonate supply to roots change availability of iron in the leaf apoplast?
(Springer, Dordrecht, 2002)
The role of the leaf apoplast in iron (Fe) uptake into the leaf symplast is insufficiently understood, particularly in relation to the supposed inactivation of Fe in leaves caused by elevated bicarbonate in calcareous ...
Roles of stolbur phytoplasma and Reptalus panzeri (Cixiinae, Auchenorrhyncha) in the epidemiology of Maize redness in Serbia
(Springer, Dordrecht, 2007)
Maize redness (MR), a disease causing midrib, leaf and stalk reddening and abnormal ear development in maize, has been reported from Serbia, Romania and Bulgaria for 50 years. Recent epiphytotics reduced yields by 40%-90% ...
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 ...
Uptake of Fe-59 from soluble Fe-59-humate complexes by cucumber and barley plants
(Springer, Dordrecht, 2002)
The capability of cucumber (Cucumis sativus L., cv. Serpente cinese), a Strategy I plant and barley (Hordeum vulgaris L., cv. Europa), a Strategy II plant to use Fe complexed by a water-soluble humic fraction (WEHS) extracted ...
A Note on Short-time Response of Two-dimensional Lattices during Dynamic Loading
(SAGE Publications, 2008)
The disordered 2D lattices are used extensively to study damage
evolution and fracture of inhomogeneous or multi-phase systems. The present note
addresses their initial elastic response during dynamic loading. Namely, a ...
Ordering effect of kinetic energy on dynamic deformation of brittle solids
(Elsevier, 2008)
The present study focuses on the plane strain problem of medium-to-high strain-rate loading of an idealized brittle material with random microstructure. The material is represented by an ensemble of “continuum particles” ...
Stolbur Phytoplasma Transmission to Maize by Reptalus panzeri and the Disease Cycle of Maize Redness in Serbia
(Amer Phytopathological Soc, St Paul, 2009)
Maize redness (MR), induced by stolbur phytoplasma ('Candidatus Phytoplasma solani', subgroup 16SrXII-A), is characterized by midrib, leaf, and stalk reddening and abnormal ear development. MR has been reported from Serbia, ...
