Late spring frosts can become one of the limiting factors for expansion cultivation area towards a harsher climate almond [Prunus amygdalus Batsch syn P. dulcis (Mill.) D.A. Webb] crop as frost damage up to 90% harvest. In order identify key genes favoring cold tolerance in almonds, branches from three late-blooming genotypes: ‘Guara’, ‘Soleta’ and ‘Belona’ were exposed at −4 °C during 24 h con...

The purpose of this study is to assess the performance of an adaptive model (AM) in estimating chlorophyll-a concentration (Chl-a) in optically complex inland waters. Chl-a modeling using remote sensing data is usually based on a single model that generally follows an exponential function. The estimates produced by such models are relatively accurate at high Chl-a concentrations, but accuracy d...

The eutrophication of the Sulejow reservoir dam in Poland is connected with the problem of toxicity of cyanobacterial blooming (blue-green algal blooming). The main species responsible for hepatotoxic "algal bloom" formation is Microcystis aeruginosa. The aim of this study is to evaluate the influence of the toxic cyanobacterial extract containing microcystins on the growth and morphology of a ...

The article presents the results of analysis cultivar composition Iris × hybrida hort. collection Nikitsky Botanical Gardens according to bloom season and color classification. As a result phenological observations, average long-term dates «beginning flowering» phase in conditions South Coast Crimea were determined for all cultivars. definition studied cultivars within garden groups into early ...

The goal of this paper is to demonstrate the use of fuzzy logic controllers in modifying the figure of a piezoceramic bimorph mirror. Non-contact electron actuation technology is used to actively control a bimorph mirror comprised two PZT-5H wafers by varying the electron flux and electron voltages. Due to electron blooming generated by the electron flux, it is difficult to develop an accurate ...
