Solar-type Stars Observed by LAMOST and Kepler

Obtaining measurements of chromospheric and photometric activity of stars with near-solar fundamental parameters and rotation periods is important for a better understanding of solar-stellar connection. We select a sample of 2603 stars with near-solar fundamental parameters from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)-Kepler field and use LAMOST spectra to measure their chromospheric activity and Kepler light curves to measure their photospheric activity (i.e., the amplitude of the photometric variability). While the rotation periods of 1556 of these stars could not be measured due to the low amplitude of the photometric variability and highly irregular temporal profile of light curves, 254 stars were further identified as having near-solar rotation periods. We show that stars with near-solar rotation periods have chromospheric activities that are systematically higher than stars with undetected rotation periods. Furthermore, while the solar level of photospheric and chromospheric activity appears to be typical for stars with undetected rotation periods, the Sun appears to be less active than most stars with near-solar rotation periods (both in terms of photospheric and chromospheric activity).Comment: 7 pages, 6 figure

Agriculture in the Guan Zhong Area of China From the Late Warring States to the End of Western Han.

The goal of my research was to depict the state of agriculture in the Guan Zhong area of China from approximately the mid-third century through the mid-first century B.C. Various kinds of source materials, most of which have an implicit or explicit relationship to the Guan Zhong area enabled me to research different aspects of contemporary agriculture. These included the administration of agriculture, agricultural dwelling places and other buildings, and agricultural activities. Available written materials provided valuable information on the farmers' obligations to the government and government attempts to promote agricultural production via government policies and designated officials. They also contained many references to how and when agricultural activities were conducted. Information on the farmers' dwelling places and surroundings, as well as some of the activities in which they engaged, was obtained from Han tomb models of farmhouses, farming machinery, and village sites. I concluded that it was possible to make an in-depth study of the state of agriculture during the Qin/Han period if one focused on the Guan Zhong region

The effect of hydroxyl on dye-sensitized solar cells assembled with TiO2 nanorods

TiO2 nanorods have been prepared on ITO substrates by dc reactive magnetron sputtering technique. The hydroxyl groups have been introduced on the nanorods surface. The structure and the optical properties of these nanorods have been studied. The dye-sensitized solar cells (DSSCs) have been assembled using these TiO2 nanorods as photoelectrode. And the effect of the hydroxyl groups on the properties of the photoelectric conversion of the DSSCs has been studiedinfo:eu-repo/semantics/publishedVersio

Die Bedeutung der funktionellen Anatomie in China für die Motorik

Zusammenfassung Zusammenfassend wurde versucht, in dieser Arbeit zu zeigen, wie die Selbstheilungskräfte aus der traditionellen chinesischen Medizin, durch die Methoden der westlichen Medizin bestätigt werden können. Die beschriebene Vergleichsstudie ist ein exemplarischer Anfang für weitere Forschung. Wenn es gelingt, die beiden medizinischen Systeme zu einer Ergänzung und gegenseitigen Verbessrung zu bringen, dann wird der Nutzen, sowohl für die gesunde Lebensführung des Einzelnen als auch der Gesellschaft groß sein
