Suture intradermiche totali
Two kind of total intradermal suture techniques are described in the present report. These procedures allow an effective reduction of post-operative pain of surgical wound, prevent infections, cut down tissutal trauma, achieve better aesthetic results, making easier postoperative patient''s management. From January 2001 to December 2007, 1,427 patients underwent surgical treatment and the wounds have been sewn with self-locking knots or intradermal skin closure with introflecting knots. This kind of procedures allow a sharp reduction of postoperative pain as well as the incidence of wound infections. Also the number of wound medication required after surgery is significantly reduced.
Precision electroweak measurements on the Z resonance
We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, $\MZ$ and $\GZ$, and its couplings to fermions, for example the $\rho$ parameter and the effective electroweak mixing angle, are precisely measured. The number of light neutrino species is determined to be 2.9840…
