    Now the 2011 is a Year of Russian Cosmonautic as it was announced according to the edict of President of Russia Federation. The 50 years from the first human's flight into the space is being marked this year. On 12 April, 1961, for the first time in human's history the Soviet citizen Yuri Gagarin was a first man to perform a flight into the space on board of Vostok spaceship. Having flown around the planet he successfully landed. It was a 108 minutes' flight, only one circle which became the greatest event not only for 20b century but also for history of civilization. All-Russian Research Institute of Vegetable Breeding and Seed Production as some other Research Institutes of RAAS have been now working out the foodstuffs for cosmonauts since the time when Russian Space Exploration Program began.2011 год Указом Президента РФ объявлен Годом российской космонавтики. В этом году весь мир отмечает 50-летие первого полета человека в космос. 12 апреля 1961 года впервые в истории человечества гражданин Советского Союза Юрий Гагарин совершил космический полет на корабле «Восток». Облетев земной шар, он благополучно вернулся на Землю. Эти 108 минут вокруг планеты, всего один виток, явились одним из величайших событий не только ХХ века, но и всей истории цивилизации

    Orbital Observations of Dust Lofted by Daytime Convective Turbulence

    Over the past several decades, orbital observations of lofted dust have revealed the importance of mineral aerosols as a climate forcing mechanism on both Earth and Mars. Increasingly detailed and diverse data sets have provided an ever-improving understanding of dust sources, transport pathways, and sinks on both planets, but the role of dust in modulating atmospheric processes is complex and not always well understood. We present a review of orbital observations of entrained dust on Earth and Mars, particularly that produced by the dust-laden structures produced by daytime convective turbulence called “dust devils”. On Earth, dust devils are thought to contribute only a small fraction of the atmospheric dust budget; accordingly, there are not yet any published accounts of their occurrence from orbit. In contrast, dust devils on Mars are thought to account for several tens of percent of the planet’s atmospheric dust budget; the literature regarding martian dust devils is quite rich. Because terrestrial dust devils may temporarily contribute significantly to local dust loading and lowered air quality, we suggest that martian dust devil studies may inform future studies of convectively-lofted dust on Earth

    О СУЩЕСТВОВАНИИ ЗАРОДЫШЕЙ НИЗКОТЕМПЕРАТУРНОЙ ФАЗЫ В ТЕМПЕРАТУРНОЙ ОБЛАСТИ УСТОЙЧИВОГО СОСТОЯНИЯ ВЫСОКОТЕМПЕРАТУРНОЙ ФАЗЫ

    It is shown, that after achievement of the certain stable size in residual volumes of low-temperature phase, acted at heating in temperature area of a steady condition of a high-temperature phase, and also germs low-temperature phase, formed at temperatures of same area, additional both the increase, and decrease of their sizes should be accompanied by heat evolution. Due to fact that it is forbidden from a position of a principle of Le Shatelier-Brown such low-temperature phase volumes can exist indefinitely long in balance with a high-temperature phase. Показано, что после достижения определенного стабильного размера остаточными объемами низкотемпературной фазы, поступивших при нагреве в температурную область устойчивого состояния высокотемпературной фазы, а также зародышами низкотемпературной фазы, образовавшимися при температурах этой же области, дополнительное как увеличение, так и уменьшение их размеров должно сопровождаться выделением теплоты. А так как это запрещено с позиции принципа Ле Шателье-Брауна, то такие объемы низкотемпературной фазы могут бесконечно долго существовать в равновесии с высокотемпературной фазой.
