Exceptional sea turtle nest records in 2011 suggest an underestimated nesting potential in Sicily (Italy)
We report seven nesting events by loggerhead sea turtles in Sicily (Italy) in 2011. In comparison to past records, this number is relatively high and may be at least in part due to an awareness campaign carried out in 2011 to solicit such reports. This suggests that Sicily may host a much higher nesting activity than previously thought and higher monitoring effort is recommended, especially in certain coastal tracts. Sand temperatures and incubation periods indicate that the beaches monitored so far in the southern coast are not optimal for development, resulting in low hatching success, and produce a majority of males. Five 2011 nests and two past nests from the same area had mtDNA haploty…
Search for supersymmetric particles using acoplanar charged-particle pairs from Z0 decays
We have performed a search for supersymmetric particles using acoplanar pairs of oppositely-charged particles in decays of the Z0. In 0.53 pb−1 of integrated luminosity near the Z0 peak, we observe two events where approximately four are expected from background, allowing limits to be extended on combined photino and slepton masses, and also on combined photino and chargino masses.
ALEPH: a Detector for Electron-Positron Annihilations at LEP
Process-centred Software Engineering Environments (PSEE) are the most recent generation of environments supporting software development activities. Most of PSEE are based on mechanisms promoting enforcement and automation of process activities. In this kind of mechanisms the process models are prescribed in a detailed and complete way. But the experience shows that supporting processes is more concerned with the flexibility of guidance offered during the process performance than with enforcement of a collection of predefined process models. In this paper, we present a solution to support strategic processes in a PSEE by providing a flexible guidance during process enactment.
