Almeida-Pititto, B.; Gimeno, S. G.A.; Freire, R. D.; Ribeiro-Filho, F. F.; Ferreira, S. R.G.; Osiro, K.; Iunes, M.; Matsumura, L. K.; Moises, R. C.S.Made available in DSpace on 2022-04-28T18:55:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2006-01-01; We evaluated the relationship of leptin with hypertension adjusted for body mass index (BMI) and/or waist circumference in a population of Japanese-Brazilian women aged ≥30 years with centrally distributed adiposity. After excluding diabetic subjects, the study subjects - who participated in a populatio...

Tests of Lorentz invariance at the Sudbury Neutrino Observatory
SNO collaboration (133 authors); Barros, N.; Chauhan, D.; Maneira, J.; Prior, G.Experimental tests of Lorentz symmetry in systems of all types are critical for ensuring that the basic assumptions of physics are well-founded. Data from all phases of the Sudbury Neutrino Observatory, a kiloton-scale heavy water Cherenkov detector, are analyzed for possible violations of Lorentz symmetry in the neutrino sector. Such violations would appear as one of eight possible signal types in the detector...
Search for neutron-antineutron oscillations at the Sudbury Neutrino Observatory
SNO collaboration (124 authors); Barros, N.; Chauhan, D.; Maneira, J.; Prior, G.Tests on B-L symmetry breaking models are important probes to search for new physics. One proposed model with Δ(B-L)=2 involves the oscillations of a neutron to an antineutron. In this paper, a new limit on this process is derived for the data acquired from all three operational phases of the Sudbury Neutrino Observatory experiment. The search concentrated on oscillations occurring within the deuteron, and 23 e...
Current Status and Future Prospects of the SNO+ Experiment
SNO+ collaboration (156 authors); Andringa, S.; Barros, N.; Carvalho, J.; Chauhan, D.; Lozza, V.; Maio, A.; Maneira, J.; Prior, G.SNO+ is a large liquid scintillator-based experiment located 2km underground at SNOLAB, Sudbury, Canada. It reuses the Sudbury Neutrino Observatory detector, consisting of a 12m diameter acrylic vessel which will be filled with about 780 tonnes of ultra-pure liquid scintillator. Designed as a multipurpose neutrino experiment, the primary goal of SNO+ is a search for the neutrinoless double-beta decay (0$\nu\bet...

W.; Bialek, A.Published in "Neutrino Masses and Oscillations" of Advances in High Energy Physics (Hindawi); SNO+ is a large liquid scintillator-based experiment located 2km underground at SNOLAB, Sudbury, Canada. It reuses the Sudbury Neutrino Observatory detector, consisting of a 12m diameter acrylic vessel which will be filled with about 780 tonnes of ultra-pure liquid scintillator.

Improvement of the energy resolution via an optimized digital signal processing...
GERDA collaboration (114 authors); Barros, N.An optimized digital shaping filter has been developed for the Gerda experiment which searches for neutrinoless double beta decay in$^{76}$ Ge. The Gerda Phase I energy calibration data have been reprocessed and an average improvement of 0.3 keV in energy resolution (FWHM) corresponding to 10 % at the $Q$ value for $0\nu \beta \beta $ decay in$^{76}$ Ge is obtained. This is possible thanks to the enhanced low-f...
Combined Analysis of all Three Phases of Solar Neutrino Data from the Sudbury N...
SNO collaboration (123 authors); Barros, N.; Maneira, J.; Prior, G.; Chauhan, D.We report results from a combined analysis of solar neutrino data from all phases of the Sudbury Neutrino Observatory. By exploiting particle identification information obtained from the proportional counters installed during the third phase, this analysis improved background rejection in that phase of the experiment. The combined analysis resulted in a total flux of active neutrino flavors from 8B decays in th...
Measurement of the $\nu_e$ and Total $^{8}$B Solar Neutrino Fluxes with the Sud...
SNO collaboration (150 authors); Barros, N.; Chauhan, D.; Maneira, J.; Prior, G.This paper details the solar neutrino analysis of the 385.17-day phase-III data set acquired by the Sudbury Neutrino Observatory (SNO). An array of 3He proportional counters was installed in the heavy-water target to measure precisely the rate of neutrino-deuteron neutral-current interactions. This technique to determine the total active 8B solar neutrino flux was largely independent of the methods employed in ...
Urban photochemical pollution in the Iberian Peninsula: Lisbon and Barcelona ai...
Barros, N.; Borrego, C.; Toll, I.; Soriano, C.; Jiménez, P.; Baldasano, J. M.Numerical simulations with photochemical transport models were independently performed for two domains situated in the Iberian Peninsula covering the Lisbon and Barcelona airsheds. Although the days chosen for simulation of the two cities are not the same, the synoptic situations in both cases, known as typical summertime situations, were similar, which allowed the development of typical mesoscale circulations,...
