Numerical study of the scaling properties of SU(2) lattice gauge theory in Palumbo non-compact regularization

In the framework of a non-compact lattice regularization of nonabelian gauge theories we look, in the SU(2) case, for the scaling window through the analysis of the ratio of two masses of hadronic states. In the two-dimensional parameter space of the theory we find the region where the ratio is constant, and equal to the one in the Wilson regularization. In the scaling region we calculate the lattice spacing, finding it at least 20% larger than in the Wilson case; therefore the simulated physical volume is larger.Comment: 24 pages, 7 figure

Continuous wound infiltration of local anesthetics in postoperative pain management: Safety, efficacy and current perspectives

Local infiltration and continuous infusion of surgical wound with anesthetics are parts of multimodal analgesia for postoperative pain control. The techniques, given the simplicity of execution that does not increase the timing of the intervention and does not require additional technical skills, are applied in several kinds of surgeries. The continuous wound infiltration can be used for days and a variety of continuous delivery methods can be chosen, including patient-controlled analgesia, continuous infusion or intermittent bolus. The purpose of this narrative review is to analyze the literature, in particular by researching the safety, efficacy and current perspectives of continuous wound infiltration for postoperative pain management in different surgical settings. We have identified 203 articles and 95 of these have been taken into consideration: 17 for the lower limb surgery; 7 for the upper limb surgery, 51 for the laparotomy/ laparoscopic surgery of the abdominopelvic area, 13 studies regarding breast surgery and 7 for cardiothoracic surgery. The analysis of these studies reveals that the technique has a variable effectiveness based on the type of structure involved: it is better in structures rich in subcutaneous and connective tissue, while the effectiveness is limited in anatomic districts with a greater variability of innervation. However, regardless the heterogeneity of results, a general reduction in pain intensity and in opioid consumption has been observed with continuous wound infiltration: it is an excellent analgesic technique that can be included in the multimodal treatment of postoperative pain or represents a valid alternative when other options are contraindicated

Life Cycle Assessment: Sviluppo di indicatori specifici per l'Italia per la fase di valutazione d'impatto

After a brief recall and a short description of the LCA (Life Cycle Assessment) methodology, whose aim is to define and evaluate the environmental impacts related to a product service within its life cycle, the work is focused on the second step of LCA methodology: the Impact Assessment step. In particular you can find: -a review of the state of the art -a critical identification of environmental indicators, of normalisation and weightening principles for the different environmental categories specific for Italy. Then you will find the application of the methodology to a case study concerning the production of butter by the Consorzio Granterre of Modena. In conclusion, some considerations are done about the status and the limitations of the actual development, in particular referring to the Impact Assessment step.
