We have proposed and validated the hamster cheek pouch model of oral cancer for boron neutron capture therapy (BNCT) studies and shown that boronophenylalanine delivers potentially therapeutic 36.9 +/- 17.5 ppm boron to tumor tissue with tumor:normal tissue and tumor:blood ratios of 2.4:1 and 3.2:1, respectively. Here we report the first evidence of the usefulness of BNCT for the treatment of o...

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...

An accelerator-based BNCT facility is under development at the Lawrence Berkeley National Laboratory. Neutrons will be produced via the 7Li(p,n) reaction at proton energies of about 2.5 MeV with subsequent moderation and filtering for shaping epithermal neutron beams for BNCT. Moderator, filter, and shielding assemblies have been modeled using MCNP. Head-phantom dose distributions have been cal...

Introduction: For this investigation we have used neutron spectroscopy data gathered with HEND/GRS instrument onboard Mars Odyssey. Starting from 2002 this mission passed through primary and several extended phases accumulating enormous data volume. During this mission one has been proved that orbital mapping of neutron flux from martian surface (instruments HEND, NS and GRS) is powerful method...

Largely enhanced parity-violating effects observed in compound resonances induced by epithermal neutrons are currently attributed to the mixing of parity-unfavored partial amplitudes entrance channel states. Furthermore, it is proposed that same mechanism enhances parity-violation also breaking time-reversal-invariance nucleus. The entrance-channel induces energy-dependent spin-angular correlat...

Neutron Resonance Transmission Analysis (NRTA) is a spectroscopic technique which uses the resonant absorption of neutrons in epithermal range to infer isotopic composition an object. This has relevance many traditional fields science and nuclear security. NRTA past made use large, expensive accelerator facilities achieve precise neutron beams, significantly limiting its applicability. In this ...
