Multi criteria evaluation of a sustainable alkali-activated concrete
The construction industry is one of the most polluting sectors worldwide. In order to reduce the environmental footprint, novel green materials and processes are being considered by valorising and reusing wastes. This work investigates the production of a novel and sustainable geopolymeric concrete reusing biomass fly ash from kraft paper-pulp industry. In particular, this paper aims to evaluate the best combination of the aggregate granulometry used in the material production. For this purpose, the multicriteria method TOPSIS has been implemented in order to obtain a rank of the concrete specimens. In this approach only mechanical aspects have been considered and future developments will i…
Did the covid-19 pandemic change hip fracture incidence in elderly?
The purpose of this study was to analyze the impact of the national lockdown on femoral neck fractures occurred in the elderly in an Italian city with more than 650 thousand people. We analyzed data related to patients over 65 years-old with femoral neck fractures admitted between March 9th and April 24th, 2020 to five public Hospitals in Palermo and four private Hospitals during lockdown. A total of 152 patients with hip fracture were observed with a significant reduction compared with the same period in 2017-2019. During the Lockdown period a reduction was observed of the mean age from 84.2 ±2.6 years old to 82.5±1.2 with a higher incidence in males, particularly in < 80-year-olds. The…
