Introduction: The dominant cause for lunar visible color differences is variations in the degree of soil maturity and the abundance of FeO and opaque minerals, such as ilmenite. The addition of opaque minerals to a lunar soil tends to decrease the overall reflectance and continuum slope (darkens and decreases “redness”). As a soil weathers its reflectance is also lowered but its slope increases...

introduction bnct is an effective method to destroy brain tumoral cells while sparing the healthy tissues. the recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. in this paper, it is indicated that using d-t neutron source and optimizing of beam shaping assembly (bsa) leads to treating brain tumors in a reasonable time where all iaea ...

The large magnitude and the sign correlation effect in the parity non-conserving resonant scattering of epithermal neutrons from Th is discussed in terms of a non-collective 2p− 1h local doorway model. General conclusions are drawn as to the probability of finding large parity violation effects in other regions of the periodic table. PACS numbers: 25.40.Ny, 11.30.Er, 24.10.Ht, 24.80.Dc CTP# 229...

INTRODUCTION Several compositions of neutron filters have been installed at the channel No. 4 of the Dalat research reactor to produce quasi-monoenergetic neutron beams. However, this neutron facility has been proposed to enhance the quality of the experimental instruments, and to characterize the neutron spectrum parameters for new filtered neutron beams of 2 keV, 24 keV, 59 keV and 133 keV. ...

A review of gold and bearing base metals deposits in Chile, indicate the existence at least six different type ore deposits, most largely formed during Cenozoic with predominance Miocene. Mesozoic are common but less relevant regarding their size content. These hydrothermal genetically associated subduction related Andean arc magmatism. Due to its relationship episodic magmatism migrating eastw...
