Solar Flares, the Solar Corona, and Solar Physics [PDF]
Symposium - International Astronomical Union, 2000 The Sun serves as the local physics laboratory for studying the suprathermal activity phenomena of stars. Scrutiny of the Sun has led to the discovery of a host of previously unknown physical effects, largely within the classical physics of Newton and Maxwell, but including quantum mechanics and lepton physics as well.

The solar oscillations spectrum and the solar cycle [PDF]
Symposium - International Astronomical Union, 1988 During the summer seasons of the years 1977 to 1985 daily velocity measurements of solar global oscillations have been obtained using a resonant scattering spectrometer. After calculating the power spectra of the daily residuals, the mean for each season is found.

Agroeconomic effect of soil solarization on fall-planted lettuce [PDF]
, 2002 The effects of summer soil solarization on the production and economics of four lettuce cultivars were evaluated in two plantings conducted during the fall growing season of 2001, to determine the feasibility of integrating strip-solarization in ...

New Directions for Adult and Continuing Education, EarlyView.ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Effect of application of soil solarization on biological control of soil pathogens and vegetable yield in greenhouse [PDF]
Selekcija i Semenarstvo, 2019 The development of weeds and soil pathogens in greenhouse significantly reduces the yield of cultivated crops. Suppression of soil pathogens using conventional methods (chemicals) leads to contamination of both soil and water.
