Guided modes in left-handed waveguides
(OPTICS COMMUNICATIONS, 2008)
We investigate basic properties of linear guided modes in a waveguide slab with the core of a material with simultaneously negative effective permittivity and permeability surrounded by a normal dielectric cladding. The ...
Desert crossing strategies of migrant songbirds vary between and within species
(nature, 2019)
Each year, billions of songbirds cross large ecological barriers during their migration. Understanding
how they perform this incredible task is crucial to predict how global change may threaten the safety
of such journeys. ...
A comparative study of antioxidative activities of cell-wall polysaccharides
(Elsevier Sci Ltd, Oxford, 2011)
Oxidative burst in plants is elicited by biotic and abiotic stressors. Analogously to some monosaccharides which act as intracellular antioxidants, cell-wall polysaccharides may be in charge of buffering free-radical ...
Role of fructose in the adaptation of plants to cold-induced oxidative stress
(Springer, New York, 2008)
This work presents findings, which indicate important role of fructose, fructose 6-phosphate (F6P), and fructose 1,6-bisphosphate (FBP) in preservation of homeostasis in plants under low temperature. Cold combined with ...

Determinants of avian malaria prevalence in mountainous Transcaucasia
(Springer Link, 2018)
Deforestation, urban development, and global climate change can lead to dramatic changes of ecological communities and increase
prevalence of infectious diseases at higher latitudes and altitudes. Identification of factors ...
VARIABILITY OF ANATOMICAL AND MORPHOLOGICAL TRAITS OF PINUS NIGRA AND PINUS SYLVESTRIS SEEDLINGS AFFECTED BY DIFFERENT CONTAINER TYPE
(Wood Research – VUPC, a.s. (Pulp and Paper Research Institute), 2024)
In the paper was analysed the influence of three different container types, used for
cultivation of Pinus nigra and Pinus sylvestris seedlings, on dimensions of their anatomical
(resin ducts width, resin ducts number, ...
Changes in antioxidative enzymes activities during Tacitus bellus direct shoot organogenesis
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2012)
Changes in antioxidative enzymes activities during Tacitus bellus direct shoot organogenesis from leaf explants were examined. During the early stages of shoot organogenesis there was a decrease in superoxide dismutase ...
Changes in activities of antioxidant enzymes during Chenopodium murale seed germination
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2008)
The activities and isoenzyme pattern of catalase (CAT), superoxide dismutase (SOD) and peroxidase (POD) have been studied during germination of Chenopodium murale seeds. CAT and SOD activities were similar in dry seeds and ...
