Development of testing protocols for the measurement of pure and blended hydrogen in natural gas grids: An outlook from the THOTH2 project

Transporting or blending hydrogen (H2) into the existing gas infrastructure can be crucial in the European green transition. However, the regulation of this matter is still debated by interested stakeholders. The THOTH2 project aims to fill normative gaps by developing new protocols for assessing the limits and tolerances of state-of-the-art (SoA) instrumentation installed in natural gas (NG) transmission and distribution grids. This paper outlines the methodology used for selecting the devic...

Breakdown of knowledge authority: semiotic analysis of an anti-vax conspiracy theory influencer on Twitter

Anti-vax conspiracy theories are major drivers of “vaccine hesitancy”, a top-10 threat to global health according to the WHO. This paper investigates the interpretative mechanisms and discursive conditions of anti-vax discourse on Twitter (X), through the analysis of seven tweets posted by an anti-vax influencer. Mixed methods of discourse analysis are employed, focusing on the strategic character and potential social effects of discourse. As a set of relations, the code-text of anti-vax cons...

Machine Learning Clustering of Water-Water Interactions in the Cambridge Structural Database

This study investigated the application of clustering machine learning techniques to analyze water-water contacts in crystal structures deposited in the Cambridge Structural Database. The initial dataset was divided into three groups regarding interaction energies between water molecules, and were separately analyzed. The application of machine learning methods enabled finding similar groups of contacts and defining their geometrical parameters. By carefully scrutinizing geometric parameters ...
