The objective of this study is to demonstrate the feasibility of constructing a compact neutron detector that is sensitive to thermal and epithermal neutrons and has high rejection efficiency relative to gamma-ray background. A two-channel high-pressure He scintillation detector is considered for the detection of neutrons in coincidence mode. The detector consists of two large avalanche photodi...
Global distributions of thermal, epithermal, and fast neutron fluxes have been mapped during late southern summer/northern winter using the Mars Odyssey Neutron Spectrometer. These fluxes are selectively sensitive to the vertical and lateral spatial distributions of H and CO2 in the uppermost meter of the martian surface. Poleward of +/-60 degrees latitude is terrain rich in hydrogen, probably ...
Epithermal neutron capture and transmission measurements were performed using the timeof-flight method at the Rensselaer Polytechnic Institute linac using metallic Nb samples. The capture measurements were made at the 25-m flight station with a 16-section sodium iodide multiplicity detector and the transmission measurements at the 25-m flight station with a 6Li glass scintillation detector. Res...
translation studies have become an accepted academic subject and books, journals and doctoral dissertations appear faster than one can read them all (bassnet and lefevere, 1990). but this field also brought with itself so many other issues which needed to be investigated more, in the heart of which, issues like ideology, ethics, culture, bilingualism and multilingualism. it is reported that ove...
background: boron neutron capture therapy (bnct) is a very promising treatment for patients suffering gliobastoma multiforme, an aggressive type of brain cancer, where conventional radiation therapies fail. thermal neutrons are suitable for the direct treatment of cancers which are located at near-tissue-surface deep-seated tumors need harder, epithermal neutron energy spectra. materials and me...
The accuracy of data-driven predictive mineral prospectivity models relies heavily on the training datasets used. These are usually trained using data for “known” deposit locations as well “non-deposit” that based randomly generated point patterns. In this study, related to Seabridge Gold Inc Iskut project, an epithermal Au in northwestern British Columbia (BC), Canada, used test utility modeli...
