    Toxoplasmosis in livestock in Italy: an epidemiological update

    Infection with Toxoplasma gondii is one of the most common parasitic infections of human being and other warm-blooded animals. It has been found worldwide from Alaska to Australia. Public health organizations repeatedly encourage the collection of accurate data about T. gondii in animals and humans due to its medical importance as a major source of parasitic zoonosis. For these reasons, epidemiological updates on toxoplasmosis in livestock are strongly advised also to plan control strategies. In the present paper, seroprevalence data on T. gondii that have been recorded in livestock from different Italian regions over the last 3 decades are reviewed, showing the high level of exposure of livestock to this parasite

    I principi del "giusto procedimento" e del "giusto processo" tributario si integrano, alla luce della Costituzione italiana e delle regole consolidate a livello comunitario e del diritto internazionale tributario. Occorre apprestare garanzie e tutele al contribuente già nella fase di esercizio dei poteri istruttori. Eventuali violazioni delle stesse, anche nella successiva fase dell'accertamento, si proietteranno nella fase giurisdizionale e saranno oggetto di valutazione del giudice

    The paper deals with an analytical method that allows to compute the system state matrix A and the input matrix B and consequently to achieve the time domain linearised response (under step input vector u) by applying a matrix exponential technique in order to investigate the dynamic behaviour of Dispersed Generator (DG) in a MV distribution system, and the role played by the different load dynamics. The use of matrix exponential applied to power system appears to be attractive for software implementation on mathematical commercial packages, because of both its electrical evidence and its analytical conciseness
