Effect of Co substitution on Ni2_{2}MnGe Heusler alloy: ab initio study

Ab initio calculations shown that the Co substitution instead of Ni in Ni$_{2}$MnGe with the L2$_{1}$ crystallographic structure leads to a decrease of the lattice constant and an increase of the total magnetic moment of the Ni$_{2-x}$Co$_{x}$MnGe compounds. The Mn(B) has the largest local moment above $3~\mu_{B}$ coupled parallel to moments on the Ni(A,C) and Co(A,C), which are found in the ranges of $0.19\div0.26~\mu_{B}$ for Ni(A,C) and $1.03\div0.97~\mu_{B}$ for Co(A,C) for studied range of $x$. Using the results stemming from the total energy calculations, the values of bulk modulus and its pressure derivatives are estimated according to the Murnaghan EOS.Comment: 3 pages, 3 figures; The European Conference Physics of Magnetism 2017; submitted to Acta Physica Polonica

Broadcasting to the masses or building communities: Polish political parties’ online performance during 2011 elections in international perspective

This paper analyses within the context of election contests the extent to which parties use the range of Web 2.0 tools, in particular social networking sites, weblogs and microblogs, in order to build communities online; we contrast this with the more traditional political use of the online environment for broadcasting. Using the 2011 Polish general election as a case study, we analyse the use of the online environment by all political parties, categorising features as offering a range of functions to serve visitors, from informing to allowing interaction. We also assess how different groups of visitors are targeted through different features or platforms. The data from the content analysis thus provides a rich picture of the online strategy of each party and the extent to which the Internet was used in the campaign. These data are supplemented by web cartography analysis which identifies the interlinkages between the websites of political parties, official information sources and the media. The cartography allows us to analyse the direction of traffic flow within the electoral websphere, the extent to which parties create open platforms with high levels of linkage to one another or if they maintain enclosed communities linking only to supportive sites. Overall our paper will provide an understanding of party election strategies during elections allowing discussion regarding the impact this might have on parties, media actors and voters. In particular we demonstrate how parties can use the range of web features to build communities of specific groups of visitors, in particular those with issue specific interests, those leaning towards supporting a party, and existing partisan campaigners. The use of these tools, we argue, can increase loyalty and lead to the conversion of supporters to activists. The paper leads into a discussion of how social networking tools have the potential to enhance the link between parties, members and supporters but that this depends on how the party utilises the online environment. Finally we aim to fit the Polish case study within a larger picture of political parties’ online performance during elections. Here we will compare our data on Poland with similar data which analysed the performance of parties in German 2009 general elections, parliamentary elections in Great Britain 2010 and French parliamentary election in 2012

Static Buckling of FML Columns in Elastic-Plastic Range.

The paper deals with the elasto-plastic buckling of thin-walled Fiber Metal Laminates short columns/profiles subjected to axial uniform compression. Structures of open and hollow (closed) cross-sections are considered build of at plate walls. Multilayered FML walls are considered as built of alternating layers of aluminum and fiber-glass composite. Three elastic-plastic theories are employed for constitutive relations description of aluminum layers i.e. fully elastic material behavior, the J2-deformation theory of plasticity and the J2 flow theory later both with Ramberg-Osgood formula application, whereas composite layers are assumed elastic within whole loading range. Some exemplary results determined with the application of own analytical-numerical method based on the Koiter's theory, in the Byskov and Hutchinson formulation are enclosed in the form of tables and plots

MEPs online: Understanding communication strategies for remote representatives

This article explores the use of the Internet by Members of the European Parliament (MEPs), assessing the adoption of online communication as well as its strategic uses. In particular we analysed the websites, weblogs and social networking site profiles of all MEPs who linked to an online presence from the European parliament homepage, a total of 440 MEPs representing all 27 member nations. Through a thorough analysis of the content using a scheme designed to record the presence and functionality of 103 specific features and tools and recency of updates, we assess how MEPs use the Internet to connect with a range of audiences; from journalists to loyal supporters. We find MEPs embracing a range of features which would be appealing to a wide range of different visitors. There is a minor generational divide among MEPs based both on their age and the length of time their country has been a member of the European Union. However overall we suggest there is an ebb and flow of innovation within the online political communication of these parliamentarians
