High temperature abatement of acid gases from waste incineration. Part I: experimental tests in full scale plants.

In recent years, several waste-to-energy plants in Italy have experienced an increase of the concentration of acid gases (HCl, SO2 and HF) in the raw gas. This is likely an indirect effect of the progressive decrease of the amount of treated municipal waste, which is partially replaced by commercial waste. The latter is characterised by a higher variability of its chemical composition because of the different origins, with possible increase of the load of halogen elements such as chlorine (Cl) and fluorine (F), as well as of sulphur (S).

High temperature abatement of acid gases from waste incineration. Part II: Comparative life cycle assessment study.

The performances of a new dolomitic sorbent, named Depurcal®MG, to be directly injected at high temperature in the combustion chamber of Waste-To-Energy (WTE) plants as a preliminary stage of deacidification, were experimentally tested during full-scale commercial operation. Results of the experimentations were promising, and have been extensively described in Biganzoli et al. (2014).

Interleukin 1, interleukin 6, interleukin 10, and tumor necrosis factor α in active and quiescent systemic lupus erythematosus.

Objectives: Several studies have investigated the cytokine profile of patients with systemic lupus erythematosus (SLE); however, their role is still controversial, mostly because SLE has a heterogeneous disease manifestation. We measured 4 of the most important cytokines in patients with SLE after dividing them in uniform groups according to disease activity and organ involvement.

Materials And Methods: Eighty-two adult female patients with SLE were divided into 3 groups according to disease activity and organ involvement: Group A (SLE activity index [SLEDAI] score, 7 ± 0.

PCDD/Fs in ambient air in north-east Italy: the role of a MSWI inside an industrial area.

The stack gases of a municipal solid waste incinerator (MSWI), and ambient air were sampled in four locations around the plant for the analysis of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs). The sampling area was close to an industrial area near Trieste, in north-east Italy. The purpose of the study was to estimate the impact of the MSWI emissions and to distinguish the contribution of these emissions from other potential emission sources in the industrial area.

13C-breath tests in hepatology (cytosolic liver function).

13C-phenylalanine (PheBT) and 13C-galactose breath tests (GBT) explore non invasively the hepatic functional mass by measuring two enzymatic activities localized into the cytosol of liver cells: the phenylalanine hydroxylase (which converts phenylalanine into tyrosine) and the galactose kinase (which catalyzes the ATP-dependent phosphorylation of galactose to galactose 1-phosphate). Both BTs are safe and accurate in predicting the severity of liver cirrhosis showing a good correlation with the Child-Pugh score. PheBT is also used in predicting postoperative complications and monitoring liver regeneration in patients undergoing partial hepatectomy.
