In contrast to several types of marbles used in antiquity, where different data collections do exist, similar approaches for provenance analysis are not available for limestones. In general, limestones are characterised visually and by the examinatio...
The present paper describes the development of a multisensory system for the analysis of the natural water in the Danube, water collected in the neighboring area of Galati City. The multisensory system consists of a sensor array made up of six screen...
One of the last wild populations of the critically endangered stellate sturgeon (Acipenser stellatus) survives in the Danube River. Limited knowledge about the genetic structure, ecology, and evolution of this species led to poor and inconsistent man...
This review paper aims to analyze studies conducted over recent years (2011–2021) on hydrocarbon pollution in the Danube’s Romanian sector. This involves looking at three main issues: Space-related Romanian Danube hydrocarbon pollution; t...
Roman Limesgebiet was both a border between the Greco–Roman world and barbaricum, but also the contact area between these two parts of the ancient oicumene. In Moesia Inferior, this area was established after the Roman conquest in the 1st centu...
