... Существуют календари, в которых указываются неблагоприятные дни и дни магнитных бурь. ... Предварительно взяв данные в городской библиотеке, о днях магнитных бурь в 2000- 2002 г., мы сравнили, когда дети болели после своего рождения. ... Во время магнитных бурь, у детей, родившихся в эти дни, коэффициент корреляции составил 0,38. Для детей, родившихся в дни немагнитных бурь коэффициент корреляции равен 0,04. ... Для детей, родившихся в дни магнитных бурь, коэффициент корреляции равен 0,44. ...
... Day З In common usage the word "day" unfortunately has two different meanings: (1) the period of time when the Sun is up (what we have been calling "daytime") (2) the period of time between consecutive sunrises (or sunsets), or one daytime + one nighttime. ... The sky turns dramatically dark and bright stars and planets can be seen. ... З The planets move roughly along the same path as the Sun and Moon. ... The Moon took a month to circle the sky, the Sun a year, each planet its own period of time. ...

... Maps of six sources (0420+022, 0420-014, 1308+326, 1345+125, 1803+784, and DA 193) obtained with milliarcsecond resolution are presented and discussed, together with their broadband (122 GHz) spectra obtained on the RATAN600 radio telescope at epochs close to those of the VLBI observations. ... The image (Fig. 5) shows that the source structure at 18 cm is compact, consisting of a VLBI core and two jet components, with the outer component lying 5 mas (30 pc) to the northwest of the core ( = 54 ). ...
