Heritage, Green, Energy communities: comunità resilienti icone di sostenibilità

Lo scritto si sforza di sottrarre i concetti di sostenibilità e di sviluppo sostenibile da quell’aura di vaghezza che ad essi viene sovente attribuita attraverso l’esame di talune realtà concrete che, alla stregua di icone, danno ad essi un volto percepibile. A tale scopo prende in considerazione in una prospettiva unitaria tre tipi di comunità, le heritage communities, le green communities e le energy communities, le quali risultano ulteriormente accomunate dall’essere espressione di resilie...

The Yang–Mills–Higgs functional on complex line bundles: Asymptotics for critical points

We consider a gauge-invariant Ginzburg–Landau functional (also known as Abelian Yang–Mills–Higgs model), on Hermitian line bundles over closed Riemannian manifolds of dimension n ≥ 3 . Assuming a logarithmic energy bound in the coupling parameter, we study the asymptotic behaviour of critical points in the London limit. After a convenient choice of the gauge, we show compactness of finite-energy critical points in Sobolev norms. Moreover, thanks to a suitable monotonicity formula, we pr...

Impact of an air bubble within the syringe on test results obtained with a modern blood gas analyzer

Background. Minimizing air aspiration by carefully filling blood gas syringes is crucial to prevent air contamination from causing undesirable variations in gasses and other molecules. While some previous studies investigated this aspect, these are now outdated and only analyzed a limited number of blood gas parameters. Thus, we investigated the effects air contamination in the syringe using a modern blood gas analyzer. Methods. We sampled venous blood from 17 laboratory workers (mean age: 4...

Effect of exogenous lipids contamination on blood gas analysis

Objectives. The purpose of this study was to investigate the effects of contamination of venous blood with a lipid-containing solution on parameters measured by a modern blood gas analyzer. Methods. We collected venous blood from 17 healthcare workers (46 ± 11 years; 53 % women) into three blood gas syringes containing 0 , 5 and 10 % lipid-containing solution. Blood gas analysis was performed within 15 min from sample collection on GEM Premier 5000, while triglycerides and serum indices were...

Mpox (Monkeypox) diagnostic kits - September 2024

To better describe the current diagnostic alternatives for diagnosing mpox, a search was conducted on the FIND initiative website, the global alliance for diagnostics. As of September 1, 2024, the FIND website lists 131 mpox diagnostic tests. The majority of 98 (74.8%) tests are based on DNA detection using NAATs, while 18 (13.7%) tests detect mpox antigens, 13 (9.9%) tests detect anti-mpox antibodies, 1 (0.8%) test detects both mpox antigens and anti-mpox antibodies and 1 (0.8%) test detects...
