The fluctuations, under time reversal, of the natural time and the entropy distinguish similar looking electric signals of different dynamics

We show that the scale dependence of the fluctuations of the natural time itself under time reversal provides a useful tool for the discrimination of seismic electric signals (critical dynamics) from noises emitted from man made sources as well as for the determination of the scaling exponent. We present recent data of electric signals detected at the Earth's surface, which confirm that the value of the entropy in natural time as well as its value under time reversal are smaller than that of the entropy of a "uniform" distribution.Comment: 29 pages including 24 figure and 1 Tabl

BlogForever D3.2: Interoperability Prospects

This report evaluates the interoperability prospects of the BlogForever platform. Therefore, existing interoperability models are reviewed, a Delphi study to identify crucial aspects for the interoperability of web archives and digital libraries is conducted, technical interoperability standards and protocols are reviewed regarding their relevance for BlogForever, a simple approach to consider interoperability in specific usage scenarios is proposed, and a tangible approach to develop a succession plan that would allow a reliable transfer of content from the current digital archive to other digital repositories is presented

Report on the development of the national method for the assessment of ecological status of natural lakes in Greece, with the use of littoral benthic invertebrates

This report discusses the development of a national method for the assessment of ecological status of natural lakes in Greece, based on the Biological Quality Element (BQE) “Benthic Invertabrate Fauna” from the littoral zone, the Hellenic assessment method for Lake Littoral Benthic invertebrate fauna (HeLLBI). Most lake assessment methods based on benthic macroinvertebrates to date, evaluate eutrophication and acidification; fewer methods assess morphological pressures on lake ecosystems and they are mostly based on benthic macroinvertebrates from the littoral zone (Poikane et al., 2016). Greece has a national method for zoobenthos from the profundal zone (GLBiI - Greek Lake Benthic invertebrate Index), that addresses eutrophication, which is included in the 2018 Intercalibration Decision [Commission Decision (EU) 2018/229] (Ntislidou et al., 2018). The development of the current assessment method, as described in this report, is based on data from the national water monitoring network. In particular, 109 littoral sampling sites in 21 lakes (29 lake years) have been surveyed for benthic invertebrates during the 2015-2018 sampling campaign. Natural lakes in Greece are grouped into 3 types, according to the mixing regime and depth gradient1. As the sampling took place in the littoral zone, data from all lake types were pooled in the dataset. The HeLLBI method consists of metrics indicative of taxonomic composition and abundance, sensitivity/tolerance of taxa and taxa diversity. It addresses morphological alteration and eutrophication pressures

Molecular Detection of the 1BL.1RS Translocation in Hellenic Bread Wheat Cultivars

The main motive of the present work was to detect and confirm the presence of the 1BL.1RS wheat-rye translocation in elite Hellenic bread wheat germplasm. For this, a molecular method was employed and seven Hellenic bread wheat cultivars (Acheloos, Acheron, Chios, Elisavet, Myconos, Orpheus, and Vergina) were studied. A rye population originated from Florina, and cultivar Kavkaz/Cgn, one of the donors of the 1BL.1RS translocation to bread wheat, were used as positive checks. The polymerase chain reaction was applied and two promoters for bread wheat gene alleles located on short arm of chromosome 1B (GLU-B3, GLI-B3) and one promoter for a rye gene (SEC I) located on short arm of chromosome 1R, were involved. It was demonstrated that cultivars Acheron, Elisavet and Orpheus do carry the 1BL.1RS translocation, whereas the rest of the varieties studied, they do not it. It was concluded that cultivars Acheron, Elisavet and Orpheus that carry the translocation, could be crossed to other elite genotypes lucking the translocation and produce new varieties possessing the advantages of the 1BL.1RS translocation. A special attention should be given to cultivar Acheron since this cultivar, despite the presence of the translocation carries favourable alleles in other gene loci affecting positively the quality of the produced bread
