The use of hafnium-tungsten chronometry to date the Moon is hampered by cosmogenic tungsten-182 production mainly by neutron capture of tantalum-181 at the lunar surface. We report tungsten isotope data for lunar metals, which contain no 181Ta-derived cosmogenic 182W. The data reveal differences in indigenous 182W/184W of lunar mantle reservoirs, indicating crystallization of the lunar magma oc...

objectives: the present study was carried out to investigate the relationship between different lunar phases and the occurrence of overdose attempted suicide. method: the study was carried out for a period of three lunar years (shaban 1416 to shaban 1419) with patients admitted to the intoxication emergency clinic at imam reza hospital in mashad. in this research, 13422 cases of suicide attempt...

The role of triangle mechanism in the decay process $J/\psi \to K^- K^+ a_1(1260)$ is probed. In this mechanism, a close-up resonance with mass $1823$ MeV and width $122$ decays into $K^* \phi, K^* K \pi$ then \bar{K}$ fuses $a_1(1260)$ resonance. We find that leads to singularity around $M_{\rm inv}(K^- a_1(1260))\approx 1920$ MeV, where axial-vector meson considered as dynamically generated W...

the age of criminal responsibility of children in the islamic penalties act has been determined as religious bulugh (puberty) nasab. according to this, criminal authorities hold girls criminally liable and punishable at 9 complete lunar years and boys at 15 complete lunar years. unfortunately, our legislator has set criminal responsibility of children based on sexual maturity; therefore, thousa...

Recent paleomagnetic studies of Apollo samples have established that a core dynamo existed on the Moon from at least 4.2 to 3.56 billion years (Ga). Because there is no lunar dynamo today, a longstanding mystery has been the origin of magnetization in very young lunar samples (<~200million years old (Ma)). Possible sources of this magnetization include transient fields generated bymeteoroid imp...

This paper shows how the exposure of the Moon to the Earth’s plasmasheet is subject to decadal variations due to lunar precession. The latter is a key property of the Moon’s apparent orbit around the Earth – the nodes of that orbit precess around the ecliptic, completing one revolution every 18.6 years. This precession is responsible for a number of astronomical phenomena, e.g. the year to year...

www.sciencemag.org SCIENCE VOL 323 13 FEBRUARY 2009 843 COVER An image of Mare Moscoviense on the lunar farside, taken by the Terrain Camera aboard the SELENE (Kaguya) spacecraft on 17 January 2008. Crater frequency distributions derived from such images yield ages of about 2.5 billion years for several volcanic deposits in this mare, indicating that volcanism on the lunar farside lasted about ...
