La responsabilità dei preposti per la sicurezza dei lavoratori nel SSN: indagine conoscitiva in alcune aziende sanitarie siciliane.
Gli autori analizzano la figura professionale del preposto nell'ambito delle Strutture Sanitarie sottolineando le responsabilità ricadenti su detto operatore, anche alla luce di alcune sentenze della Cassazione (civile e penale), IV sezione. Vengono inoltre presentati i risultati di una indagine conoscitiva condotta mediante distribuzione di un questionario anonimo ai preposti di alcune Aziende Sanitarie Siciliane
First results of the CAST-RADES haloscope search for axions at 34.67 $��$eV
We present results of the Relic Axion Dark-Matter Exploratory Setup (RADES), a detector which is part of the CERN Axion Solar Telescope (CAST), searching for axion dark matter in the 34.67$��$eV mass range. A radio frequency cavity consisting of 5 sub-cavities coupled by inductive irises took physics data inside the CAST dipole magnet for the first time using this filter-like haloscope geometry. An exclusion limit with a 95% credibility level on the axion-photon coupling constant of g$_{a��}\gtrsim 4\times10^{-13} \text{GeV}^{-1}$ over a mass range of 34.6738 $��$eV < $m_a$ < 34.6771 $��$eV is set. This constitutes a significant improvement over the current strongest limit set by CAST…
Multifocal biliary cystadenocarcinoma of the liver: CT and pathologic findings.
Biliary cystadenocarcinoma is a rare tumor that originates from the hepatobiliary epithelium. Although this tumor can affect any portion of the biliary tree, intrahepatic location is more common. It is usually a slow growing tumor and often asymptomatic until it reaches a considerable size. The lesion is most often solitary and large when discovered; multiple lesions or metastases within the liver are very rare. A 63-year-old man was referred to our institute for weight loss, abdominal discomfort, worsening bulky symptoms in the right upper abdominal quadrant, and an increase in serum aminotransferases that had been present for several months. Spiral CT of the abdomen demonstrated two lesio…
