Application of small-size antennas for estimation of angles of arrival of HF signals scattered by ionospheric irregularities

A modification of the Doppler Interferometry Technique is suggested to enable estimating angles of arrival of comparatively broadband HF signals scattered by random irregularities of the ionospheric plasma with the use of small-size weakly directional antennas. The technique is based on the measurements of cross-spectra phases of the probe radiation recorded at least in three spatially separated points. The developed algorithm has been used to investigate the angular and frequency-time characteristics of HF signals propagating at frequencies above the maximum usable one (MUF) for the direct radio path Moscow-Kharkiv. The received signal spectra show presence of three families of spatial components attributed, respectively, to scattering by plasma irregularities near the middle point of the radio path, ground backscatter signals and scattering of the sounding signals by the intense plasma turbulence associated with auroral activations. It has been shown that the regions responsible for the formation of the third family components are located well inside the auroral oval. The drift velocity and direction of the auroral ionosphere plasma have been determined. The obtained estimates are consistent with the classical conception of the ionospheric plasma convection at high latitudes and do not contradict the results of investigations of the auroral ionosphere dynamics using the SuperDARN network.     

Genetic differentiation induced by spaceflight treatment of Cistanche deserticola and identification of inter-simple sequence repeat markers associated with its medicinal constituent contents

The dried, fleshy stems of Cistanche deserticola (Orobanchaceae) are popular tonics in Traditional Chinese Medicine (TCM) to treat the inability of kidney in expelling extra fluid in the body, causing fluid retention, and reform reproductive system. However, the wild plants of C. deserticola have become endangered due to habitat downsizing and over-harvesting for its medicinal usages. The present research was carried out for the following purposes: (1) promoting the space-breeding research; (2) providing molecular evidence for agricultural selective breeding; and (3) protecting this endangered herbal medicine and conserving its genetic resources.

翅片位置对复合式减涡器减阻性能影响数值模拟

为了探索翅片-管复合式减涡器的翅片安装位置对共转盘腔径向内流压力损失的影响规律,对不同转速、翅片周向位置及安装角度下的去旋系统开展了数值研究,得到了不同工况下共转盘腔径向内流的流场结构及压力损失分布曲线。研究结果表明:减涡管能引导流体径向流入,并降低流体的旋流比;相比于管式减涡器,翅片-管复合式减涡器能明显降低盘腔内的总压损失;在不同旋转雷诺数下,翅片的周向安装位置α及安装角β均存在最佳值;在中、高旋转雷诺数下,最佳值分别为α=9°,β=30°,最佳结构下总压损失较基础模型低40%左右;改变翅片周向位置及安装角度可以明显改变气流进入减涡管的角度,在较优情况下,可以减小流体流入减涡管的阻力及在减涡管内的流动阻力,整体上减小了盘腔内总压损失。
