Many studies exist on magmatic volatiles (H, C, N, F, S, Cl) in and on the Moon, within the last several years, that have cast into question the post-Apollo view of lunar formation, the distribution and sources of volatiles in the Earth-Moon system, and the thermal and magmatic evolution of the Moon. However, these recent observations are not the first data on lunar volatiles. When Apollo sampl...

Introduction: Before establishing a human outpost on the Moon, numerous problems associated with lunar dust must be addressed and mitigated [1, 2]. The deleterious nature of lunar dusts was experienced during all Apollo missions. Lunar dusts (brought in on dirty spacesuits and boots) contaminated the atmosphere in the lunar module and irritated the eyes, sinuses, and throats of the astronauts [...

The potential diagnostic and prognostic value of D-dimer for AAA was assessed in this study. 1260 men from a population-based ultrasound screening study were included, of which 299 had small AAAs monitored by repeat ultrasound for a median of 5 years. 132 patients referred to a vascular clinic were also recruited, of which 41 had an AAA. The potential diagnostic and prognostic value of D-dimer ...

Microbial reductive dechlorination of commercial polychlorinated biphenyl (PCB) mixtures (e.g., Aroclors) in aquatic sediments is crucial to achieve detoxification. Despite extensive efforts over nearly two decades, the microorganisms responsible for Aroclor dechlorination remained elusive. Here we demonstrate that anaerobic bacteria of the Dehalococcoides group derived from sediment of the Hou...

We report recent measurements of the CKM angle α using data collected by the BABAR detector at the PEP-II asymmetric-energy e+e− collider at the SLAC National Accelerator Laboratory. In addition to improved constraints on α from the decays B± → ρ±ρ0, we also present preliminary results of neutral and charged B meson decays to K1(1270)π and K1(1400)π and its impact on the estimate for the CKM an...

In October of 2005, the European Space Agency (ESA) and Alcatel Alenia Spazio released a "call to academia for innovative concepts and technologies for lunar exploration." In recent years, interest in lunar exploration has increased in numerous space programs around the globe, and the purpose of our study, in response to the ESA call, was to draw on the expertise of researchers and university s...

One of the oqtical datasets for optimal selection of future lunar lana_ng sites is local, to regional-scale topography. Lunar base site selection will require such data for hoth engineering and scientific olX,rations purposes. The Lunar Geosctence Orbiter or Lunar Obsert_or is the ideal precursory science mission from which to obtain this required information. We suggest that a simple laser alt...

A global scheme of Lunar-Earth Information Network is proposed in this paper. It is composed of a lunar-earth Messenger, a lunar Orbiter and a Lunar Probe net, through which an information collection and communication network is formed. Moreover, the triune exploration and project features are described in detail. Keyword: LunarNet, Messenger, Orbiter, Lunar Probes
