We report the observation of spontaneous and very sharp resistivity jumps at low temperatures in antiferromagnetic itinerant-electron system La0.825Ce0.175Fe12B6. This intermetallic compound undergoes multiple magnetic transformations, antiferromagnetic–ferromagnetic (AFM–FM) ferromagnetic–paramagnetic (FM–PM), triggered by changes both temperature applied field. The magnetoresistance isotherms...

Microbial community structure and diversity in the wide and shallow Venice lagoon were assessed, prior to construction of mobile dams, at nine stations representative of four different sub-basins previously selected on the basis of international guidelines for sediment quality. The sediments were mainly anoxic and were colonized by microbial communities the species richness of which was quantit...

Impact of Atlantic salmon (Salmo salar) cage culture in Mjoifjordur, Eastern Iceland on the chemistry of the sediment was investigated. Sediment samples were collected using a Shipek grab on 29.12.2003. A core sub-sample has taken from each grab for analyzing total organic matter, total organic carbon, total nitrogen and phosphorus in different depths of samples from three stations at various d...

To realize a sustainable society, “green technology” with low (or even zero) CO2 emissions, is required. A key material in such technology permanent magnet because it utilized for electric-power conversion several applications including electric vehicles (EVs), hybrid EVs (HEVs), and turbines wind power generation. highly efficient conversion, stronger than Nd–Fe–B necessary. One potential cand...

This study provides taxonomic and ecological data on Hemiptera (Insecta) order prevalence in Berati region habitats Southern Albania. Diverse natural environments, fields, hilly mountainous characterize this region. The expeditions for the biological material collection were organized during 2018-2020 six stations from May to September. Our refers 38 species, representing 28 genera 10 families ...

clustering technique is one of the most important techniques of data mining and is the branch of multivariate statistical analysis and a method for grouping similar data in to same clusters. with the databases getting bigger, the researchers try to find efficient and effective clustering methods so that they can make fast and real decisions. thus, in this paper, we proposed an improved ant syst...

When establishing the relative distance between two GNSS–GPS stations with sub-centimeter accuracy, it is necessary to have auxiliary data, some of which can only be collected some time after the moment
