Search for the disappearance of muon antineutrinos in the NuMI neutrino beam
We report constraints on muon antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 +/- 11.7(stat) ^{+10.2}_{-8.9}(syst) events under the assumption |dm2bar|=2.32x10^-3 eV^2, snthetabar=1.0. A fit to the two-flavor oscillation approximation constrains |dm2bar|<3.37x10^-3 eV^2 at the 90% confidence level with snthetabar=1.0
Application of Probiotic Bacteria to Functional Foods
End of Project ReportProbiotic cultures are described as live microbial feed supplements that
improve intestinal microbial balance and are intended for maintenance of
health or prevention, rather than the curing of disease. The demand for
probiotic foods is increasing in Europe, Japan and the U.S. reflecting the
heightened awareness among the public of the relationship between diet
and health.
Traditionally, the most popular food delivery systems for these cultures have
been freshly fermented dairy foods, such as yogurts and fermented milks, as
well as unfermented milks with cultures added. However, in the
development of functional foods, the technological suitability of probiotic
strains poses a serious challenge since their survival and viability may be
adversely affected by processing conditions as well as by the product
environment and storage conditions. This is a particular concern, given that
high levels (at least 107 per gram or ml) of live micro-organisms are
recommended for probiotic products.
In previous studies (see DPRC No. 29) the successful manufacture of
probiotic Cheddar cheese harbouring high levels (>108 cfu/g) of the
probiotic Lactobacillus paracasei NFBC 338 strain was reported.
Hence, the overall objective of these studies was to continue the
development and evaluation of Functional Foods containing high levels of
viable probiotic bacteria, with particular emphasis on overcoming the
technological barriers and the identification of strains suited to particular
applications, such as incorporation into Cheddar cheese and spray-dried
powders.Department of Agriculture, Food and the Marin

In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4 ± 11.7(stat)^(+10.2)_(-8.9)(syst) events under the assumption │Δm^2│ = 2.32 X 10^(-3) eV^2, sin^2(2θ) = 1.0

Improved Search for Muon-Neutrino to Electron-Neutrino Oscillations in MINOS
We report the results of a search for ν_e appearance in a ν_μ beam in the MINOS long-baseline neutrino experiment. With an improved analysis and an increased exposure of 8.2×10^(20) protons on the NuMI target at Fermilab, we find 2sin^2(θ_(23))sin^2(2θ_(13))<0.12(0.20) at 90% confidence
level for δ=0 and the normal (inverted) neutrino mass hierarchy, with a best-fit of 2sin^2(θ_(23))sin^2(2θ_(13))=0.041^(+0.047)_(-0.031)(0.079^(+0.071)_(-0.053).
The θ_(13)= 0 hypothesis is disfavored by the MINOS data
