Search for Higgs boson production in association with a high-energy photon via vector-boson fusion with decay into bottom quark pairs at √s = 13 TeV with the ATLAS detector

A search is presented for the production of the Standard Model Higgs boson in association with a high-energy photon. With a focus on the vector-boson fusion process and the dominant Higgs boson decay into b-quark pairs, the search benefits from a large reduction of multijet background compared to more inclusive searches. Results are reported from the analysis of 132 fb−1 of pp collision data at √ s = 13 TeV collected with the ATLAS detector at the LHC. The measured Higgs boson signal yield in this final-state signature is 1.3 ± 1.0 times the Standard Model prediction. The observed significance of the Higgs boson signal above the background is 1.3 standard deviations, compared to an expected significance of 1.0 standard deviations

Improvement of Hardness and Microstructures by Ageing in Shape Memory CuAlNi Alloys

The shape memory CuAlNi alloys, having a composition near that of Cu3Al, exhibit disorder-order transition from the disordered bcc β-phase to the ordered β1-phase (DO3 type) at high temperatures. Although the β1-phase is a non-equilibrium phase, it nonetheless remains stable at room temperature upon quenching from the high temperature β-phase. At the lower temperatures, the β1-phase itself undergoes martensitic transformation and displays layered structure called M18R. The influence of ageing on two CuAlNi β-phase alloys was studied by measuring the time dependence of hardness, lattice parameters and by optical microscopy observation at room temperature. Hardness shows a trend to decrease with the ageing duration due to the formation of precipitation, and grain size is also affected by ageing

Synthesis and Chemical structure elucidation of two schiff base ligands, Their Iron(II) and Zinc(II) Complexes, and Antiradical, Antimicrobial, Antioxidant Properties

Background: Fe(II) and Zn(II) complex series have been synthesized from Schiff base ligands derived from furan-2-carbaldehyde and thiophene-2-carbaldehyde. Elemental, infrared, ultraviolet-visible, NMR and thermal analysis, also mass spectroscopy and magnetic susceptibility measurements were performed to explain the structures of these synthesized ligands and their metal complexes. The formulas based on analytical, spectral, and magnetic studies, the complexes can be demonstrated as [M(L1 )2 ](H2 O)n , [M(L2 )2 ](H2 O)n , where M = Zn(II) and Fe(II). An octahedral geometry was suggested for the Zn(II) and Fe(II) complexes. The antioxidant, antiradical and antimicrobial properties of the Zn(II) and Fe(II) complexes were investigated using different in vitro assays. Some of the complexes showed reasonable amount of antioxidant and antimicrobial activity. © 2016 Bentham Science Publishers

Production of a novel pectin lyase from Bacillus pumilus (P9), Purification and characterisation and fruit juice application

Extracellular pectin lyase (EC 4.2.2.10) was produced by Bacillus pumilus (P9) in solid state fermentation. Pectin lyase enzyme was purified 36.36 fold by using DEAE-cellulose anion exchange column chromatography and characterized. Molecular weight of the enzyme was determined as 25 kDa by using Sephadex G-100 gel filtration chromatography. Purification of enzyme was controlled by SDS-PAGE. The optimum pH and temperature of enzyme was determined as pH 6.0 and 60oC, respectively. Pectin lyase was mostly stable at 40°C. Its' activity deceased in 50% for 1h at 60°C and 40% for 4 h at 50°C. Vmax and KM were calculated respectively as 0.298 mg/mL and 132.6 mol/L*min. The presence of 10 mM concentration of Ca2+, Cu2+, Mn2+, Mg2+, Zn2+, Hg2+, Fe2+ and EDTA, L-cystein, ascorbic acid and -mercaptoethanol significantly enhanced the pectin lyase of the purified enzyme. The purified pectin lyase enzyme was used for getting fruits juices. It was determined that yields of fruits juices significantly improved when it was compared with control. © 2010 University of Bucharest

Processing the manuscripts of Atatürk [Atatürk̈n el yazmalarinin i̇şlenmesi]

In this paper, as a first step to an easy and convenient way to access the manuscripts of Atatürk with a word based search engine, the preprocessing of digitalized documents and their line and word segmentation is studied. The techniques that are applied on printed documents may not yield satisfactory results. Due to this fact, more developed techniques are decided to be applied consisting of a technique based on Hough transform [1] for line segmentation and a technique that is based on dealing with skewness of lines for word segmentation. The results, which are acquired through studies that are conducted on the documents provided by Afet İnan and consisting of 30 pages [2], prove to be highly accurate and promising for future researches. ©2010 IEEE
