Chemical and isotopic composition of hot spring waters in the Tacna region, Southern Peru
(Instituto Geológico, Minero y Metalúrgico - INGEMMETPE, 2018-02)
The Tacna region hosts the most promising geothermal zones of Southern Peru, comprising five main geothermal areas: Tutupaca, Calientes, Borateras, Ancocollo and Chungara- Kallapuma located along the Quaternary volcanic ...
Near threshold 7Li(p,n) 7Be reaction as neutron source for BNCT
(Pergamon-Elsevier Science Ltd, 2015-07)
7Li(p,n)7Be is an endothermic reaction and working near its threshold (1.88MeV) has the advantage of neutron spectra with maximum energies of about 100keV, considerably lower than at higher beam energies, or than using ...

A dual natural lithium formate/L-alanine EPR dosimeter for a mixed radiation field in a boron neutron capture therapy irradiation facility
(IOP Publishing, 2020-04)
Standard commercial L-alanine pellets and specially prepared natural lithium formate monohydrate powder samples of specific granulometry were irradiated in a 60Co gamma-ray irradiation plant and in the mixed field (thermal ...
Artificial neural networks to evaluate the boron concentration decreasing profile in Blood-BPA samples of BNCT patients
(Pergamon-Elsevier Science Ltd, 2011-12)
For the prediction of decay concentration profiles of the p-boronophenylalanine (BPA) in blood during BNCT treatment, a method is suggested based on Kohonen neural networks. The results of a model trained with the concentration ...
Utilization of Boron (10B) derived from fertilizer by sugar cane
(Sociedade Brasileira de Ciência do Solo, 2009)
The response to B in agricultural systems of sugar cane is still an unexplored issue; B application has however recently been widely publicized and used with a certain degree of frequency. The use of 10B-labeled fertilizers ...
