An Ab Initio Study of Pressure-Induced Changes of Magnetism in Austenitic Stoichiometric NiMnSn.

We have performed a quantum-mechanical study of a series of stoichiometric Ni2MnSn structures focusing on pressure-induced changes in their magnetic properties. Motivated by the facts that (i) our calculations give the total magnetic moment of the defect-free stoichiometric Ni2MnSn higher than our experimental value by 12.8% and (ii) the magnetic state is predicted to be more sensitive to hydrostatic pressures than seen in our measurements, our study focused on the role of point defects, in particular Mn-Ni, Mn-Sn and Ni-Sn swaps in the stoichiometric Ni2MnSn.

Experimental study of the Al-Cu-Zn ternary phase diagram.

The phase diagram of the Al-Cu-Zn ternary system was re-investigated experimentally. The current study was designed to contribute to a better description of those parts of the phase diagram, which are disputed in the current scientific literature. Mutual relations in the family of ternary intermetallic phases with cubic, rhombohedral and modulated structure at temperatures 400 °C and 550 °C were described.

Updated catalogue of Pompilidae (Hymenoptera) in Iran.

An updated list of the Pompilidae (Hymenoptera) from Iran is presented. This catalogue contains species records that were published in a 128 years period from 1888 to 2016. In all, 162 species belonging to 41 genera and three subfamilies are recorded in Iran.

Modelling of phase diagrams of nanoalloys with complex metallic phases: application to Ni-Sn.

A method for modelling of size-dependent phase diagrams was developed by combining the semiempirical CALPHAD method and ab initio calculations of surface stresses for intermetallic phases. A novel approach was devised for the calculation of surface energy, free of systematic errors from the selection of different parameters of the software (e.g.

Fauna Europaea - all European animal species on the web.

Fauna Europaea is Europe's main zoological taxonomic index, making the scientific names and distributions of all living, currently known, multicellular, European land and freshwater animals species integrally available in one authoritative database. Fauna Europaea covers about 260,000 taxon names, including 145,000 accepted (sub)species, assembled by a large network of (>400) leading specialists, using advanced electronic tools for data collations with data quality assured through sophisticated validation routines. Fauna Europaea started in 2000 as an EC funded FP5 project and provides a unique taxonomic reference for many user-groups such as scientists, governments, industries, nature conservation communities and educational programs.
