Low-impact laparoscopic (LIL) cholecystectomy is an innovative surgical protocol that combines the use of mini-laparoscopic instruments (3-mm ports) under a low- and stable-pressure pneumoperitoneum (8 mmHg), with the aim of minimizing the surgical invasiveness and the risks related to CO2insufflation on the peritoneal environment. In day-surgery settings, LIL may contribute to increase the surgical success due to several potential benefits in terms of postoperative pain intensity and time to full recovery.

The recent decades have seen large increases in the extent of urban and built-up land use. It is predicted that 60%-90% of the world population will live in cities in 2030. The loss of green areas (urban parks, avenue tree-lines, woods, hedges, private gardens and public green spaces) as a result of the increasing urbanization is a serious threat to the overall biodiversity and calls for considerations of their role, provision and management. Urban green spaces provide ecosystem services, such as offsetting carbon emission, removing air pollution and reducing noise.

The C, N and O 1s excitation and ionization processes of 5X-uracil (X = F, Cl, Br, and I) were investigated using near edge X-ray absorption fine structure (NEXAFS) and X-ray photoemission (XPS) spectroscopies. This study aims at the fine assessment of the effects of the functionalization of uracil molecules by halogen atoms having different electronegativity and bound to the same molecular site. Two DFT-based approaches, which rely on different paradigms, have been used to simulate the experimental spectra and to assign the corresponding features.
