Capital Deepening and Wage Differentials: Germany vs. US Capital deepening may affect the evolution of the wage differential between skilled and unskilled workers differently in countries with different labor market institutions. If labor market institutions raise the relative wage of unskilled workers in Germany, firms have incentives to invest relatively more into capital equipment complement...
[1] We use Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon’s Interaction with the Sun (ARTEMIS) measurements of lunar exospheric pickup ions in the terrestrial magnetotail lobes combined with a particle-tracing model to constrain the source species and distributions of the lunar neutral exosphere. These pickup ions, generated by photoionization of neutral species while th...
This chapter discusses the physical properties of the lunar surface, determined at depths varying from a few micrometers to a few tens of meters. The properties considered include geotechnical properties (those properties of a planetary surface needed to evaluate engineering problems, including the mechanical properties of soil and rock), electrical and electromagnetic properties, and the refle...
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...
The LUNASKA (Lunar UHE Neutrino Astrophysics with the Square Kilometre Array) project is a theoretical and experimental project developing the lunar Cherenkov technique for the next generation of giant radio-telescope arrays. This contribution presents our simulation results on the directional dependence of the technique for UHE neutrino detection. In particular, these indicate that both the in...
Introduction: The discovery of spinel rich rock on the Earth’s Moon, detected by the M near-IR mapping spectrometer on the Chandrayaan-1 spacecraft [1] is among the most intriguing discoveries in a time filled with lunar revelations (e.g., [2]). The M spectrometer discerned several areas on the rim of the far-side Moscoviense basin which had near-IR reflectance spectra characteristic of abundan...
Introduction: It is known that the present Moon has no global magnetic dipole field. Data from former lunar exploration programs show that the lunar magnetic field is very weak, usually just a few nT. Variations in field strength are noted in different lunar areas, e.g.: the average magnetic field in young basins and craters is between 0.5-1.5 nT, with exceptions that antipodal of Nectaris, Ser...
In June 2009 the Lunar Reconnaissance Orbiter (LRO) spacecraft was launched to the Moon. The payload consists of 7 science instruments selected to characterize sites for future robotic and human missions. Among them, the Lunar Orbiter Laser Altimeter (LOLA) was designed to obtain altimetry, surface roughness, and reflectance measurements. The primary phase of lunar exploration lasted one year, ...
