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 ...
Silicon Improves the Production of High Antioxidant or Structural Phenolic Compounds in Barley Cultivars under Aluminum Stress
(MDPI, Basel, 2019)
Aluminum (Al) toxicity is one of the main growth and yield limiting factors for barley grown on acid soils. Silicon (Si) ameliorates Al toxicity as well as it promotes the phenolic compounds production that have antioxidant ...
Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...
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” ...
Far infrared and micro structural studies of mechanically activated nickel manganite
(Elsevier Sci Ltd, Oxford, 2013)
Nickel manganite powder synthesized by calcination of a stoichiometric mixture of manganese (MnO Aldrich 99.9%) and nickel oxide (NiO Merck, 99.5%) containing 0.5 wt% CoO and Fe2O3, was additionally mechanically activated ...
Some Observations Regarding Stochasticity of Dynamic Response of 2D Disordered Brittle Lattices
(SAGE Publications, 2011)
It had been long recognized that the tensile strength of brittle materials
increases with increase of the loading rate. In the present article, a statistical
approach to rupture of a disordered 2D triangular truss lattice ...
Temperature dependence of In1-xGaxSb reflectivity in the far infrared
(Elsevier Science Sa, Lausanne, 2011)
Far infrared reflectivity spectra of polycrystalline In1-xGaxSb were measured and numerically analyzed using the classical dispersion formula and also a fitting procedure based on the modified plasmon-phonon interaction ...
Atomic Force Microscopy Stiffness Tomography on Living Arabidopsis thaliana Cells Reveals the Mechanical Properties of Surface and Deep Cell-Wall Layers during Growth
(Cell Press, Cambridge, 2012)
Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at subcellular resolution and ...
Analysis of static bending-induced compression wood formation in juvenile Picea omorika (Pancic) Purkyne
(Springer Heidelberg, Heidelberg, 2015)
Young P. omorika trees subjected to static bending showed a severe compression wood response as characterized by fluorescence spectroscopy/microscopy, which decreased in severity with height correlated with a decrease in ...
Altered state of primordial follicles in neonatal and early infantile rats due to maternal hypothyroidism: Light and electron microscopy approach
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
tThyroid hormones (TH) are one of the key factors for normal prenatal development in mammals. Previ-ously, we showed that subclinical maternal hypothyroidism leads to premature atresia of ovarian folliclesin female rat ...
