In plane performance of RC infilled frames under seismic actions: Experimental versus code provision values
No full textRecent Italian seismic events highlighted the high vulnerability frequently shown by non structural elements, especially masonry infill walls, whose severe damage caused heavy socio-economic effects. In the framework of performance-based design, NTC2008 Italian seismic code defines different limit states considering both structural and non structural elements. Specifically, for non structural elements subjected to in-plane actions, different inter-storey drift thresholds relevant to the Damage Limit State (SLD) and the Usability Limit State (SLO) are provided, although the latter is prescribed only for buildings having a remarkable impact in case of seismic event (e.g. schools) or strategic role in the emergency management (e.g. hospitals). In the paper, in order to verify the provisions given in the Italian code, the drift values relevant to the SLD and SLO Limit States have been compared with the results deriving from some experimental studies. Experimental data also permit to define a threshold value relevant to the Life Safety Limit State (SLV), which is not provided in the current version of the Italian code

NATO SPS ASI G5535 CETRARO 2019 “DETECTION, DIAGNOSIS, AND HEALTH CONCERNS OF TOXIC CHEMICAL BIOLOGICAL AGENTS"
No full textWater pollution is becoming dramatic because of increasingly invasive and deleterious anthropic activities.
A significant number of contaminants called "Emerging Pollutants” (EPs) resulting from point and diffuse pollution are present in the aquatic environment.
These compounds, belonging to pharmaceuticals, industrial chemicals, surfactants, personal care products, analgesics, antibiotics, hormones and a whole range of other pharmaceutical compounds including anti-inflammatory, anti- diabetic, and antiepileptic drugs, are not commonly monitored but have the potential to enter the environment and cause adverse ecological and human health effects (1).
The threat lies in the fact that the environmental and human toxinology of most of these compounds has not been well addressed yet and many of these compounds are not removed by the conventional WasteWater Treatment Plants (WWTPs). Moreover, when these contaminants pass through the drinking water treatment systems undergo trasformations that generate derivative substances whose chemical properties remain undetermined. For this reason, it is necessary to try to find low-cost and easy-to-handle alternative methods to solve this vast problem.
Fluoroquinolones, which are powerful antibiotics used in human and veterinary medicine for the treatment of diseases and infections are among the drugs most frequently found in environmental waters along with sulfonamides, tetracyclines and macrolides. The synergistic action of these drugs can cause what is known as "bacterial resistance", which is the cause of 700,000 annually people death in worldwide due to resistant infections according to Joint Research Center (JRC) 2018 report.. This means that if no action is taken the estimated annual deaths attributable to bacterial resistance will be 10 million by 2050.
Adsorption by using porous materials (like activated carbon, polymeric resins, natural clay and organoclay complex adsorbents) was found to be one of the most simple, efficient, cost-effective, flexible methods to remove fluoroquinolonesin the wastewater treatment process. However, this technique does not lead to the complete removal of parent chemicals and their degradation products and, consequently, other treatments are needed for their mineralization.
Advanced Oxidation Processes (AOPs) can be a good choice because, basically, involve the generation of highly reactive free radicals, which convert the organic contaminants into final non-toxic by-products.
Among the various semiconductors employed, TiO2 is the most preferable material for the photo-catalytic process (high photosensitivity, non-toxic nature, large band gap, chemical stability and low cost).
In this research the photocatalytic activity of this semiconductor immobilized onto the surface of glass borosilicate tubes was evaluated on levofloxacin (trade name Levaquin and other), which is an antibiotic used to treat a number of bacterial infections including acute bacterial sinusitis, pneumonia, urinary tract infections, chronic prostatitis, and some types of gastroenteritis. Kinetics of photoreactions were determined in ultrapure and ground water samples spiked with levofloxacin and photoproducts where identified by liquid chromatography coupled with micrOTOF-Q-II-Mass Spectrometer (LC-MS, Bruker Daltonik GmbH, Bremen)
A user's guide to optimal transport
No full textThis text is an expanded version of the lectures given by the first author in the 2009 CIME summer school of Cetraro. It provides a quick and reasonably account of the classical theory of optimal mass transportation and of its more recent developments, including the metric theory of gradient flows, geometric and functional inequalities related to optimal transportation, the first and second order differential calculus in the Wasserstein space and the synthetic theory of metric measure spaces with Ricci curvature bounded from below

Continuous Decompositions and Coalescing Eigenvalues for Matrices Depending on Parameters
No full textThis contribution is a summary of four lectures delivered by the first author at the CIME Summer school in June 2011 at Cetraro (Italy). Preparation of those lectures was greatly aided by the other authors of these lecture notes. Our goal is to present some classical, as well as some new, results related to decompositions of matrices depending on one or more parameters, with particular emphasis being paid to the case of coalescing eigenvalues (or singular values) for matrices depending on two or three parameters. There is an extensive literature on this subject, but a systematic collection of relevant results is lacking, and this provided the impetus for writing the lecture notes. During the last 15 years, Dieci has had several collaborators on the topics under scrutiny. Besides the coauthors of these lectures, the collaboration with the following people is gratefully acknowledged: Timo Eirola (Helsinki University of Technology, Finland), Jann-Long Chern (National Central University, Taiwan), Mark Friedman (University of Alabama, Huntsville) and Maria Grazia Gasparo (University of Florence, Italy).LOM
Cervical length as a screening tool for preterm birth in twin pregnancies: a systematic review and critical evaluation of quality clinical practice guidelines
No full textobjectives: twin pregnancies are at increased risk of preterm birth (PTB) compared to singletons. evaluation of cervical length (CL) represents the optimal tool to screen PTB in singleton. Conversely, there is less evidence on the use of CL in twins. Our aim was to evaluate the methodological quality and clinical heterogeneity of clinical practice guidelines (CPGs) on the CL application in twins using AGREE II methodology. methods: MEDLINE, Scopus, and websites of the main scientific societies were examined. The following aspects were evaluated: diagnostic accuracy of CL, optimal gestational age at assessment and interventions in twin pregnancies with reduced CL. the quality of the published CPGs was carried out using "the appraisal of guidelines for REsearch and Evaluation (AGREE II)" tool. The quality of guideline was rated using a scoring system. Each considered item was evaluated by the reviewers on a seven-point scale that ranges from 1 (strongly disagree) to 7 (strongly agree). A cut-off >60 % identifies a CPGs as recommended. Results: The AGREE II standardized domain scores for the first overall assessment had a mean of 74 %. The score was more than 60 % in the 66.6 % of CPGs analyzed indicating an agreement between the reviewers on recommending the use of these CPGs. A significant heterogeneity was found; there was no specific recommendation on CL assessment in about half of the published CPGs. There was also significant heterogeneity on the CL cut-off to prompt intervention. Conclusions: Despite the fact that the AGREE II analysis showed that the majority of the included guidelines are of good quality, there was a significant heterogeneity among CPGs as regard as the indication, timing, and cut-off of CL in twins as well as in the indication of interventions

Applications of LC-MS for Detection of some Chemicals and their Metabolites in Water
No full textSurface waters are at risk from certain specific chemicals (priority substances) that could cause harm to the aquatic ecosystem (fish, plants, food chain, etc.) or affect human health through exposure to water (e.g. drinking, bathing, seafood, etc.). The Water Framework Directive (WFD) [1] requires the Commission to come forward with a strategy on pollution of surface waters. The European Directive 2000/60/CE stresses the need of adopting measures against water pollution in order to achieve a progressive reduction of contaminants and recuperate water for new uses.
The main objective is the application of LC-MS for the identification of polluting chemical compounds and their degradation intermediates in water. In this poster some results are reported about the identification of:
- tetra-hydro-cannabinol (THC) and other metabolites of Cannabis found in real water samples collected from the effluent of a wastewater treatment plant (WWTP) in Vila Nova De Gaia (Portugal),
- levofloxacin and MCPA and their metabolites in water samples undergone heterogeneous photocatalytic degradation using titanium dioxide coatings (TIO2).
Results of this investigation show as the mass spectrometry is very important for the detection of different polluting chemicals at low concentration. Our and literature findings demonstrate that
- traditional water treatments are not able to remove contaminants from wastewater and consequently recalcitrant pollutant water can entry the water cycle;
- the heterogeneous photo-catalytic system tested in our experiments is able to degrade the chemicals used as model molecules and may find application in the remediation of water contaminated with recalcitrant residues due to poor efficiency of treatment plants normally adopted for the purification of wastewater.
To obtain accurate masses and molecular formulae,
to identify unknown or unexpected and unusual metabolites,
to suggest degradation pathways
the structural identification of parent molecules and derivatives in very low concentrations represents a great benefit for environmental analytical purpose
