The alpha effectiveness of the dating ESR signal in barite: possible dependence with age

Autor: Shin Toyoda, Ai Uchida, Jun-ichiro Ishibashi, Taisei Fujiwara, Hirotsugu Nishido

Publikováno v: Geochronometria. 43:174-178

The alpha effectiveness value (k-value) for the ESR (Electron Spin Resonance) signal due to SO3 - in barite was revised by comparing the dose responses of the signal intensities to gamma rays and to 4 MeV He+ ion doses in natural sea-floor hydrotherm

ESR dating of sea-floor hydrothermal barite: contribution of 228Ra to the accumulated dose

Autor: Ai Uchida, Taisei Fujiwara, Shin Toyoda, Jun-ichiro Ishibashi

Publikováno v: Geochronometria. 43:201-206

Electron spin resonance (ESR) dating of barite has been recently developed and is now practically applied to barite extracted from sea-floor hydrothermal deposits. The evolution of the accumulated dose to barite is simulated for an actual sample of b

Publikováno v: CEN case reports. 6(2)

Immune-checkpoint inhibitor nivolumab (anti-PD-1 antibody) blocks T cell inhibition and stimulate immunologic response toward cancer cells. It was also revealed that PD-1/PD-L1 interaction crucially controls the effector differentiation of auto-react

ESR dating of barite in sulphide deposits formed by the sea-floor hydrothermal activities

Autor: Taisei Fujiwara, Shun'ichi Nakai, Ai Uchida, Asako Takamasa, Shin Toyoda, Jun-ichiro Ishibashi

Publikováno v: Radiation Protection Dosimetry. 159:203-211

Barite is a mineral newly found to be practically useful for electron spin resonance (ESR) dating of sulphide deposits formed by the sea-floor hydrothermal activities. The recent studies for the properties of the ESR dating signal in barite are summa
