Deformability Tests of Pure Niobium

research team at the University of Miskolc's Faculty of Materials Science and Technology has signed a cooperation agreement with the Geneva-based European Organization for Nuclear Research (CERN) for testing of the materials employed in the Crab Cavities will be installed in the next generation of the LHC (the so-called High Luminosity Large Hadron Collider – HL-LHC). At the University of Miskolc, high purity niobium rolling experiments were carried out in conventional (unidirectional) and cross-rolled manners in order to increase the deep drawability of the final sheet. The deformability of niobium was measured by Watts- Ford and compression tests. The microstructure and anisotropy (texture) results of the initial material and the straight-rolled products are reported

The LANDSUPPORT geospatial decision support system (S-DSS) vision: Operational tools to implement sustainability policies in land planning and management

Nowadays, there is contrasting evidence between the ongoing continuing and widespread environmental degradation and the many means to implement environmental sustainability actions starting from good policies (e.g. EU New Green Deal, CAP), powerful technologies (e.g. new satellites, drones, IoT sensors), large databases and large stakeholder engagement (e.g. EIP-AGRI, living labs). Here, we argue that to tackle the above contrasting issues dealing with land degradation, it is very much required to develop and use friendly and freely available web-based operational tools to support both the implementation of environmental and agriculture policies and enable to take positive environmental sustainability actions by all stakeholders. Our solution is the S-DSS LANDSUPPORT platform, consisting of a free web-based smart Geospatial CyberInfrastructure containing 15 macro-tools (and more than 100 elementary tools), co-designed with different types of stakeholders and their different needs, dealing with sustainability in agriculture, forestry and spatial planning. LANDSUPPORT condenses many features into one system, the main ones of which were (i) Web-GIS facilities, connection with (ii) satellite data, (iii) Earth Critical Zone data and (iv) climate datasets including climate change and weather forecast data, (v) data cube technology enabling us to read/write when dealing with very large datasets (e.g. daily climatic data obtained in real time for any region in Europe), (vi) a large set of static and dynamic modelling engines (e.g. crop growth, water balance, rural integrity, etc.) allowing uncertainty analysis and what if modelling and (vii) HPC (both CPU and GPU) to run simulation modelling 'on-the-fly' in real time. Two case studies (a third case is reported in the Supplementary materials), with their results and stats, covering different regions and spatial extents and using three distinct operational tools all connected to lower land degradation processes (Crop growth, Machine Learning Forest Simulator and GeOC), are featured in this paper to highlight the platform's functioning. Landsupport is used by a large community of stakeholders and will remain operational, open and free long after the project ends. This position is rooted in the evidence showing that we need to leave these tools as open as possible and engage as much as possible with a large community of users to protect soils and land

Interaction of Azospirillum lipoferum with Wheat Germ Agglutinin Stimulates Nitrogen Fixation

In vitro, the nitrogen fixation capability of A. lipoferum is efficiently increased in the presence of wheat germ agglutinin (WGA). A putative WGA-binding receptor, a 32-kDa protein, was detected in the cell capsule. The stimulatory effect required N-acetyl-d-glucosamine dimer (GlcNAc(di)) terminated sugar side chains of the receptor and was dependent on the number of GlcNAc(di) links involved in receptor-WGA interface. Binding to the primary sugar binding sites on WGA had a larger stimulatory effect than binding to the secondary sites. The WGA-receptor complex generated stimulus led to elevated transcription of the nifH and nifA genes and of the glnBA gene cluster but not of the glnA gene from its own promoter. There may well be a signalling cascade contributing to the regulation of nitrogen fixation

1-Triphenylstannyl-2,4,5-tritertiarybutyl-1,3-diphosphole, Ph3SnP2C3But3: Preparation, X-ray crystal structure, theoretical studies and solution fluxional behaviour

The 1-triphenylstannyl-2, 4, 5-tritertiarybutyl-1,3-diphosphole, Ph3SnP2C3Bu3t, which has been synthesised from Ph3SnCl and KP2C3Bu3t, has been fully structurally characterised in the solid state but in solution undergoes ready intra-molecular shifts of the Ph3Sn-group around the 1,3-diphospholyl ring. Theoretical calculations concerning both the structure and the dynamic process are presented and discussed

Synthesis of Methylene Bridged Bis-pyrrolo[3,2-c]carbazoles <i>via</i> an Unusual Vilsmeier–Haack Product of <i>N</i>-Ethylcarbazole

<p>The unexpected result for the formylation of <i>N</i>-ethylcarbazole under the Vilsmeier–Haack conditions (POCl₃/DMF) led to the synthesis of novel methylene bridged bis-pyrrolo[3,2-c]carbazoles <i>via</i> Hemetsberger indole synthesis was reported. A plausible mechanism for the formation of unexpectedly synthesized 7,7′-methylene bis(9-ethyl-9H-carbazole-3-carbaldehyde) <b>4</b> was postulated. The full characterization data of dicarbazolylmethane <b>4</b> and the bis-pyrrolo carbazoles <b>10a-b</b> were obtained by utilizing ¹H NMR, ¹³C NMR, FT-IR, mass spectrometry and single crystal X-ray diffraction techniques.</p
