Metabolical aspects associated with incorporation and clearance of uranium by b...
Arruda-Neto, J. D.T.; Cestari, A. C.; Nogueira, G. P. [UNESP]; Fonseca, L. E.C. [UNESP]; Saiki, M.; Oliveira, E.; Manso-Guevara, M. V.; Vanin, V. R.Made available in DSpace on 2022-04-28T18:58:31Z (GMT). No. of bitstreams: 0 Previous issue date: 2005-01-01; Groups of seven-day old Cobb broilers were fed with ration doped with uranyl nitrate at a fixed concentration (of 20 ppm), and two concentrations of phytase (120 and 180 ppm). Two animals per group were sacrificed weekly up to their adulthood. Calcium and uranium concentrations in tibia were measured by...
η→γγ Decay width via the Primakoff cross section
Rodrigues, T. E.; Arruda-Neto, J. D.T.; Mesa, J. [UNESP]; Garcia, C.; Shtejer, K.; Dale, D.; Nakagawa, I.; Cole, P. L.Made available in DSpace on 2022-04-28T20:42:16Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-07-03; Incoherent η photoproduction in nuclei is evaluated at forward angles within 4 to 9GeV using a multiple scattering MonteCarlo cascade calculation with full η-nucleus final-state interactions. The Primakoff, nuclear coherent and nuclear incoherent components of the cross sections fit remarkably well prev...
Nuclear incoherent photoproduction of π0 and η from 4 to 12 GeV
Rodrigues, T. E.; Arruda-Neto, J. D.T.; Mesa, J. [UNESP]; Garcia, C.; Shtejer, K.; Dale, D.; Nakagawa, I.; Cole, P. L.Made available in DSpace on 2022-04-28T21:24:24Z (GMT). No. of bitstreams: 0 Previous issue date: 2010-08-20; The mechanism of incoherent π0 and η photoproduction from complex nuclei is investigated from 4 to 12 GeV with an extended version of the multicollisional Monte Carlo (MCMC) intranuclear cascade model. The calculations take into account the elementary photoproduction amplitudes via a Regge model and the...
