Giorgio Nicolich, father of Urology in Trieste
No full textAim of the study: Until 1918 Trieste was part of the Habsburgic Empire. In this period the city was in full economic and demographic growth. In this context, among the medical and surgical society raised the figure of Giorgio Nicolich senior, brilliant surgeon and researcher. He was initially chief of the Surgical Division and gave birth lately to the Urological Division in 1887, in which he practiced until 1925, year of retirement and death.
Materials and methods: Giorgio Nicolich was born in Venice in 1852. He graduated in 1875 at the University of Padua, and became trainee of Tito Vanzetti (1809–1888), a surgeon particularly versed in urinary tract surgery and known for both routine surgical capacity and exceptional operations, that gave throughout his activity new and advanced boundaries to the uro-nephrology field. His activity was open to novelties like the use of radio needles for prostate cancer, the use of nephrectomy, mercurial care of the syphilis. After moving to Trieste, the year after his graduation, he entered the Trieste Civic Hospital as a secondary physician of the Division for chronic syphilitic and surgical diseases and became its chief in 1886. From 1887 he obtained the urological characterization of the Division, and the other surgical specialties were transferred to the pre-existing Surgical Division and to the new 10th Division. At the end of the Great War, in 1919 he became professor of Urology, retired in 1925, after an extension for merit of 5 years. In these last years he was joined by Carlo Ravasini, who succeeded him. Nicolich died in the same year. Results: He carried out a wide activity. He attended the Parisian school of Urology with Gujon and Albarran and, in 1921, he founded the Italian Society of Urology. He was an authority in the field of urology in the national and international landscape (he was a pupil in Vienna of Theodor Billroth) and was coauthor of the “Manual of Urology” and President of the Italian Society of Urology. He became also honorary member of the Urological Society of Berlin, of the Belgian Society and member of the Academy of Medicine of Constantinople. In 1924, the year before his death, he founded the Italian Archives of Urology. Discussion: Apart from his extraordinary ability as a surgeon, Giorgio Nicolich was a member of that small number of doctors born in Trieste or came to Trieste, who created a cohesive environment of remarkable level, between the various Divisions of the City Hospital. He is credited and reminded not only for have given life to the Urology of Trieste, but for have practiced avant-garde medicine and surgery, forming a new generation of specialist surgeons

No full textA geostatistical framework for incorporating seismic tomography auxiliary data into hydraulic conductivity
No full textA geostatistical approach is presented for the inclusion of seismic tomography data and sonic log data into the estimation of hydraulic conductivity. The procedure accounts for the errors in seismic tomography inversion and for the correlation of such errors, The proposed methodology consists of two steps: (1) the cross-variogram inference is carried out using only the data at the wellbore (both hydraulic and seismic); (2) a co-kriging procedure takes the cross-well data into account to interpolate between boreholes. No postulated a-priori relationship is needed. In order to illustrate the methodology a synthetic data set is generated on the basis of evidence from published case studies and simplified physical considerations. The numerical experiments show that the choice of the excitation frequency is critical. A trade-off exists between the need for a high-resolution survey (asking for higher freqencies) and the need for a good correlation between hydraulic conductivity and seismic properties (asking for frequencies below the squirt frequency of the medium). In the simulation using seismic data with the best excitation frequency (1 kHz in this case), the mean squared error of the hydraulic conductivity estimate is two-thirds lower than using hydraulic data alone. It is important to note also that only a part of the interwell region is adequately sampled by the tomographic experiment, Such a region can be readily identified by calculating the energy of the quasi-null space, through singular value decomposition of the tomographic matrix, In planning this type of experiments, it is necessary to carefully verify case by case whether the adopted range of high frequencies does not prevent the seismic energy from propagating effectively from sources to receivers.
