RESUMEN
The NOvA experiment has seen a 4.4σ signal of ν[over ¯]_{e} appearance in a 2 GeV ν[over ¯]_{µ} beam at a distance of 810 km. Using 12.33×10^{20} protons on target delivered to the Fermilab NuMI neutrino beamline, the experiment recorded 27 ν[over ¯]_{µ}âν[over ¯]_{e} candidates with a background of 10.3 and 102 ν[over ¯]_{µ}âν[over ¯]_{µ} candidates. This new antineutrino data are combined with neutrino data to measure the parameters |Δm_{32}^{2}|=2.48_{-0.06}^{+0.11}×10^{-3} eV^{2}/c^{4} and sin^{2}θ_{23} in the ranges from (0.53-0.60) and (0.45-0.48) in the normal neutrino mass hierarchy. The data exclude most values near δ_{CP}=π/2 for the inverted mass hierarchy by more than 3σ and favor the normal neutrino mass hierarchy by 1.9σ and θ_{23} values in the upper octant by 1.6σ.
RESUMEN
The prevalence of diarrhoea in children less than 5 years of age was compared to several concurrent socioeconomic, water source, clinic usage, and disease prevalence data, using a public health surveillance system in Cayo District, Belize. The purpose was to demonstrate that socioeconomic status and water source had little effect on childhood diarrhoea. Computer analysis showed a significant relationship (p<0.002) between diarrhoeal diseases and malnutrition, abdominal pain, and attendance at the sick-child clinic. No relationship was seen between diarrhoea and primary and secondary sources of water, house construction material, crowding, degree of rurality
