Influence of climate change on wastewater treatment plants performances and energy costs in Apulia, south Italy.

This paper studies the influence of temperature and of rainfall intensity and the effect of such variations on the treatment efficiencies and on the electrical consumptions in seven medium-large size Wastewater Treatment Plants (WWTPs) in Apulia in South Italy (Bari, Barletta, Brindisi, Lecce, Foggia, Andria and Taranto). It has been observed, in the considered WWTPs, a slight but clear increase of the incoming flow due to the increase in rainfall intensity, which results to an increase of the energy consumption per incoming volume. The impact of the climate change to the incoming flow, during the last five years (2016-2020), has been assessed indicating that an increase in rainfall intensity results to an increase of the WWTPs energy consumptions per wastewater treated volume.

Evaluation of greenhouse gas emissions from aerobic and anaerobic wastewater treatment plants in Southeast of Italy.

An evaluation of the operative functioning data of 183 Wastewater Treatment Plants (WWTPs) in Apulia (Southeast of Italy) has been carried out aimed to assess their Green House Gases (GHGs) emissions and the level for which the use of anaerobic sludge treatment should be more convenient in terms of electricity consumption and of GHGs emissions. Out of the 183 studies WWTPs, 140 are practicing aerobic digestion of sludge, while the remaining 43 are practicing anaerobic digestion of sludge. WWTPs in Apulia are serving about 4,81 million PE (Population Equivalent), yielding approximately 600,000-ton equivalent CO per annum.

Quantification of Frailty Syndrome in ICU Patients with Clinical Frailty Scale.

Quantification of frailty is useful both for understanding the nature of the syndrome and for designing an ICU care plan for patients that suffer from it. Knowing the needs and deficits of each patient individually, it is possible to create a care plan suitable to cover all the patients' needs. Tools used to date to quantify frailty syndrome are the Fried phenotype, Frailty index, Edmonton Frailty Scale, and Clinical Frailty Scale.

Frailty in elderly ICU patients in Greece: a prospective, observational study.

Background: Of particular interest is the study of frailty syndrome in older patients in recent years. This syndrome is characterized by weight loss and muscle mass, a change in eating habits, movement and endurance, and a decline in cognitive function. The purpose of the study was the prevalence of frailty syndrome in subjects aged 65 years who were hospitalized in an intensive care unit (ICU) in Greece.

Application of ultra performance liquid chromatography-mass spectrometry to profiling rat and dog bile.

Reversed-phase gradient UPLC-ESI-MS, in both positive and negative ionization modes, has been applied to the analysis of untreated bile obtained from bile-cannulated rats and dogs. The use of UPLC provided a high-resolution system that enabled global metabolite profiles of bile from the two species to be obtained that were suitable for metabolomic and metabonomic applications. When these metabolite profiles were analyzed using unsupervised multivariate statistical methods, based on principle components analysis (PCA), they were correctly classified by species of origin.
