Search for Lorentz Invariance and CPT Violation with the MINOS Far Detector

We searched for a sidereal modulation in the MINOS far detector neutrino rate. Such a signal would be a consequence of Lorentz and CPT violation as described by the standard-model extension framework. It also would be the first detection of a perturbative effect to conventional neutrino mass oscillations. We found no evidence for this sidereal signature, and the upper limits placed on the magnitudes of the Lorentz and CPT violating coefficients describing the theory are an improvement by factors of 20-510 over the current best limits found by using the MINOS near detector.

Observation of muon intensity variations by season with the MINOS far detector

The temperature of the upper atmosphere affects the height of primary cosmic ray interactions and the production of high-energy cosmic ray muons which can be detected deep underground. The MINOS far detector at Soudan, MN, has collected over 67 X 10(6) cosmic ray induced muons. The underground muon rate measured over a period of five years exhibits a 4% peak-to-peak seasonal variation which is highly correlated with the temperature in the upper atmosphere. The coefficient, alpha(T), relating changes in the muon rate to changes in atmospheric temperature was found to be alpha(T) 0: 873 +/- 0: 009(stat) +/- 0.010(syst). Pions and kaons in the primary hadronic interactions of cosmic rays in the atmosphere contribute differently to alpha(T) due to the different masses and lifetimes. This allows the measured value of alpha(T) to be interpreted as a measurement of the K/pi ratio for E(p) greater than or similar to 7 TeV of 0.12(-0.05)(+0.07), consistent with the expectation from collider experiments.

Evaluation of pharmacotherapy on elderly residents of nursing homes in the north-east of Brazil

Data related to medication order and the use of medications was collected from 94 elderly medical records of two nursing homes of Aracaju (SE), The mean age was 83.2 (SD = 10.1), with most belonging to the females (63.8%). The prevalence of the use of drugs was 87.2% and the average of medicines consumed was equal to 2.7 (SD = 1.8), mainly with action in the cardiovascular and nervous systems. In this Study, the elderly population studied presented polypharmacy (18.1%), inappropriate use of drugs (28.7%) and double therapy (11.7%). Data showed the need for improvement and evaluation of the quality of pharmacotherapy to promote rational drug use in the elderly population.
