The traditional Chinese “Twelve Flora” refer to the images of twelve flower gods corresponding months lunar calendar. They are usually composed celebrities in history and subject matter paintings, closely related festival cultures. This paper mainly uses research methods iconography, formal analysis prototype theory study Twelve Flora middle Qing Dynasty. While examining visual images, it metho...
Introduction: The chemical reactivity of lunar re-golith is one of the most important issues which impacts the human health and biological effects of lunar regolith. The constant micrometeorite bombardment of the lunar surface results in both comminution and shock melting of lunar regolith. In addition, radiation effects are likely to enhance the chemical reactivity of lunar regolith. With resp...
Lunar Laser Ranging studies the Moon’s internal structure and properties by tracking the variations in the orientation and tidal distortion of the Moon as a function of time. Future missions to the Moon’s surface should include new laser ranging instrumentation capable of improved range accuracy. A Planetary Science Decadal Survey White Paper: “Lunar Science and Lunar Laser Ranging” Page 1 of 7...
BACKGROUND It is a common belief in medical community that lunar phases have an impact on human health. A growing body of evidence indicates that lunar phases can predict the risk to develop acute neurological and vascular disorders. The goal of present report was to present our institution data and to perform systematic review of studies examining the association of intracranial aneurysm ruptu...
Introduction. Most lunar meteorites have unique cosmic-ray exposure (CRE) histories with long exposure times on the Moon, followed by very short transfer times from the Moon to Earth, typically 10-10 yr. Due to these short transfer times of lunar meteorites in space, the inventories of most cosmogenic radionuclides with half-lives of 10-10 yr contain contributions from exposure in the lunar reg...
Introduction: The discovery of hydroxyl [OH] and/or water [H2O] widely distributed on the lunar surface [1,2,3], outside of the permanently shadowed polar regions, adds significant evidence that the Moon is not completely devolatilized as had previously been assumed [4,5]. Lunar surface hydration is most likely an exogenic process, resulting from solar wind protons interacting with oxygen-rich ...
Introduction: The 22 km ∅ crater “Giordano Bruno” is the youngest lunar crater of its size or larger [1]. The crater is located at 36N / 103E in the Th-poor lunar highlands and has a prominent ejecta ray system. According to urban ledgend formation of the Giordano Bruno crater was observed by medieval monks on June 18, 1178 A.D [2]. However, formation of a 22 km sized crater on the Moon would...
One of the minor constituents of the solar wind which has been implanted in the lunar regolith over its several billion year history, is helium 3 (He-3), a rare isotope of helium which has two protons and a single neutron in its nucleus. Helium 3 is a potential fuel that can be used in near-aneutronic advanced nuclear fusion reactors for generating electric power on earth in a safe and environm...
Living in the tidal zones of the sea requires synchronization with the dominant environmental influences of tidal, solar, and lunar periodicity. Endogenous clocks anticipate those geoclimatic changes and control the respective rhythms of vital functions. But the underlying mechanisms are only partly understood. While the circadian clocks in animals are investigated employing neurobiological, mo...
