[Epidemiology of rotavirus infections in a randomized study in various central-southern areas of our country].

The etiology of diarrhea and intestinal deficiency relative to the absorbency of glucose and some enzymes can be found in Rotavirus infection. The epidemiology of this infection has been derived by the authors even if the research was limited to some areas of central-south Italy, analyzing seroimmunologically serums randomly selected. The research outcomes fully explain the first mentioned disease because antibody markers have been founded in most of the examined people

Recent trends in power system reliability and implications for evaluating future investments in resiliency

This study examines the relationship between annual changes in electricity reliability reported by a large cross-section of U.S. electricity distribution utilities over a period of 13 years and a broad set of potential explanatory variables, including weather and utility characteristics. We find statistically significant correlations between the average number of power interruptions experienced annually and above average wind speeds, precipitation, lightning strikes, and a measure of population density: customers per line mile. We also find significant relationships between the average number of minutes of power interruptions experienced and above average wind speeds, precipitation, cooling degree-days, and one strategy used to mitigate the impacts of severe weather: the amount of underground transmission and distribution line miles. Perhaps most importantly, we find a significant time trend of increasing annual average number of minutes of power interruptions over time—especially when interruptions associated with extreme weather are included. The research method described in this analysis can provide a basis for future efforts to project long-term trends in reliability and the associated benefits of strategies to improve grid resiliency to severe weather—both in the U.S. and abroad

A PRECISION EXPERIMENT ON ELECTRONS, PHOTONS AND MUONS AT LHC

We describe the upgrade of the L3 detector for running at LHC. The principle goals are the precise measurement of electrons, photons and muons
