Exploring New Horizons for Wine Grapes: Modulating Functional Effects by Varying Harvest Timing and Solar Exposure

open access: yesFoods
Grenache (GN) and Cabernet Sauvignon (CS) are two traditional red grape varieties widely cultivated in the Mediterranean area and both late-ripening cultivars, which makes them less sensitive to global warming conditions and more stable to harvest timing.

DIAGNOSTICS OF LOCAL MAGNETIC FIELDS IN SOLAR FLARES USING FeI 5383 AND MgI 5528 LINES

open access: yesOdessa Astronomical Publications, 2014
Main  purpose of  the  present work is  to estimate upper limit of the local magnetic field strength in solar flares  using spectral lines FeI  5383  and MgI  5528. These lines like FeI 5233  have  low  Landé  factors  (1.12 and 1.00,  respectively) and

CALIBRATION OF SIBERIAN RADIOHELIOGRAPH IMAGES

open access: yesSolar-Terrestrial Physics, 2019
We discuss the method for automatic calibration of solar radio images derived from the first stage of the multiwave Siberian Radioheliograph (SRH-48). SRH is a 48-element T-shaped radiointerferometer in the 4–8 GHz frequency range. Since the end of 2017,
