Implementation of DNA metabarcoding for diatoms environmental monitoring is now moving from a research to an operational phase, requiring rigorous guidelines and standards. In particular, the first steps diatom process, which consist sampling storage, have been addressed in various ways scientific pilot studies need be rationalised. The objective this study was compare three currently applied p...

Preserving our cultural heritage – from fragile historic textiles such as national flags to heavy and seemingly solid artifacts recovered from 9/11 – requires careful monitoring of the state of the artifact and environmental conditions. The standard for a web-accessible textile fiber database is established with Dublin Core elements to address the needs of textile conservation. Dynamic metadata...
