The measurement of sin(2beta)

Since the first observation in 1964, CP violation remains one of the most elusive aspects of the standard model. The CDF collaboration has reported the first evidence of CP violation in the B system using the world's largest sample of $B \to J/\psi K^0_S$ decays. The direct measurement of sin$(2\beta)$=0.79$^{+0.41}_{-0.44}$ (combined statistical and systematic error) agrees with the standard model predictions. New data collected from the B-factories and from the upgraded experiments at the Tevatron should allow a more precise measurement of $\sin 2\beta$ in the near future.Comment: Presented at Heavy Flavours 8, Southampton, UK, 1999.

The Importance of Silicon Detectors for the Higgs Boson Discovery and the Study of its Properties

Recent studies are presented demonstrating the important role played by silicon detectors in the the discovery of the Higgs boson. CMS is planning to replace its in an extended technical stop of the LHC in the winter of 2016 . We present results showing that this replacement will significant increase the sample of Higgs bosons that will be reconstructed enabling precision studies of this particle.Comment: on behalf of the CMS Collaboratio

ADRION : Charter routes from antiquity to modern times.

The Adriatic Sea has always been a busy sea from every point of view. Egidio Ivetich explains it well in an essay presented in this volume and in one of his recent works called “History of the Adriatic”. The traffic in this Sea can be measured according to the number of ships that, before the pandemic, used to land and depart from the Adriatic ports: more than 40.000 in total. An impressive number especially if compared to its Western sibling, the Tyrrhenian Sea whose yachting traffics are more intense. If we compare the current situation with a not too distant past, we can understand how the role of this “liquid territory” (a neologism invented by the memorable Fernand Braudel) - as a system of relationships- has not changed much. An immense “space-movement”, an impressive traffic system made of liquid plains connected through a series of wide or narrow doors. Herodotus, who believed the Adriatic was not a sea but rather a piece of land, was the first one to recognize the ambivalence of this Sea whose function has always been to connect rather than divide

Piracicaba river basin : mechanical and chemical erosion

It was carried out the characterization of the mechanical and chemical erosive processes in the Piracicaba River basin, for the period 1992-1996, in terms of the fluvial transport of dissolved and particulate materials. The mechanical erosion was calculated from the suspended sediment transport in the basin, considering the surface runoff discharge and the respective concentration calculated taking in account the statistical hydrogram separation method employed. The specific physical degradation calculated for the Piracicaba River basin was 90 t/km2.a, which correspond the velocity of the soil thickness reduction of about 64 m/Ma. The dissolved load of Piracicaba River was corrected due to the influence of the atmospheric inputs, mainly for SO4 2-, Ca2+ and Mg2+ (79.6; 63.8 and 41.8%, respectively). After the input corrections, it was estimated the total atmospheric/soil CO2 consumed during the silicate weathering (229 x 103 moles/km2.a) and the total chemical erosion (16.6 t/km2.a) expressed in terms of the total dissolved solids transported in the basin. The velocity of the silicate rock profile reduction (2.8 m/Ma) was calculated by the fluvial transport of dissolved silica knowing the mean silica concentrations in the parent rock and in the soil profile
