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

Line segmentation of Ottoman documents [Osmanlica belgeleri̇n satirlara bölütlenmesi̇]

Many researches and historians from all around the world are interested in historical Ottoman archives. However, translation of these documents requires competent historians which is not a feasible method in terms of time and cost. Thus, automatic translation of these documents are required. In this paper, preprocessing steps of accessing the Ottoman manuscripts with a word based search engine is studied. These preprocessing steps are binarization and line segmentation of digitalized documents. The traditional line segmentation methods applied to printed documents do not yield to satisfactory results for historical and handwritten documents. Due to this fact, more complex line segmentation techniques must be used. In this study, we developed a projection profile based method for line segmentation and local binarization is used. The experiments are conducted on a 120 page Ottoman archive and the results show that the proposed system is successful. © 2012 IEEE

The synthesized ligands and their complexes were tested for antibacterial activity against Escherichia coli ATCC 25922, Enterococcus faecalis ATCC 29212, Staphylococcus aureus ATCC 25923, and Salmonella typhimurium CCM 583. Some of complexes showed medium-level antibacterial activity against the test bacteria compared with ampicillin. © 2015 by the authors; licensee MDPI, Basel, Switzerland

Relationship of Sexuality with Psychological and Hormonal Features in the Menopausal Period

Women may experience some mental and sexual problems between the ages of 40 years and 60 years due to serious changes in the hormonal system. The aim of this study was to examine the relationships between the changes in sex hormones, sexual behaviours, depression and anxiety levels of women who were in either the premenopausal, perimenopausal or postmenopausal period. The subjects of this cross-sectional study consisted of 324 women who attended the Gynaecology and Obstetrics Out-Patient Ward of Celal Bayar University Hospital. Of this group, 37.0% (n = 124) were postmenopausal, 27.2% (n = 84) perimenopausal and 35.8% (n = 116) premenopausal. Beck Depression Inventory (BDI), State and Trait Anxiety Inventories (STAI-I and II) and a questionnaire on sexual behaviour which was prepared for this study by the authors, were applied to all of the attendees and serum sex hormone levels were analyzed. Beck Depression Anxiety, STAI-I and STAI-II scores and sexual behaviours did not show any statistically significant difference among these three groups. The frequency of sexual intercourse was lower in women with high BDI scores. The rate of painful intercourse was higher in women with high STAI-I scores. The frequency of sexual intercourse, sexual desire and orgasm decreased and painful intercourse increased in women with high STAI-II scores. The frequency of sexual intercourse decreased significantly as the age or follicle stimulating hormone level of women increased. These findings have revealed that the menopausal state did not affect the sexual behaviour, and psychological state of women between the ages of 40 and 60 years, but the increase in anxiety and depression scores affected the sexual life in a negative manner

Evaluation of Surface Properties of Four Tooth-Colored Restorative Materials

The aim of this study is to compare microhardness, roughness and micromorphology of the examined materials of a newly developed glass carbomer dental filling material to two different resin modified glass ionomers and a glass ionomer dental filling material. Specimens tested were prepared from a glass carbomer without gloss (Glass Carbomer, GCP), a glass carbomer (Glass Carbomer, GCP) with gloss, two different resin modified glass ionomers (Fuji II LC, GC and Riva LC, SDI) and a glass ionomer (Equia, GC). Seven specimens of each material were prepared according to manufacturer's recommendations. After setting, samples were polished and stored in 37°C distilled water for 24 h. Indentation microhardness of examined restorative materials was measured using the Vickers indenters. In addition surface roughness of the materials was measured using surface profilemeter. Surface morphology was analyzed by using scanning electron microscopy. There was a significant difference in microhardness and roughness between the restorative materials (p<0.05). The highest microhardness was measured for Equia and lowest for glass carbomer with gloss. The roughness was fully definite for the glass carbomer with gloss and indefinite for the glass carbomer without gloss. Small cracks and voids were observed in all groups. High viscosity glass ionomer cement Equia exhibits the high physical strength than RMGIC. Gloss application does not influence the hardness behavior of GCP

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

Study of structure and spectral characteristics of the Zinc(II) and Copper(II) complexes with 5,5-dimethyl-2-(2-(3-nitrophenyl) hydrazono)cyclohexane-1,3-dione and their effects on optical properties and the developing of the energy band gap and investigation of antibacterial activity

A new chelating ligand, 5,5-dimethyl-2-(2-(3-nitrophenyl) hydrazono)cyclohexane-1,3-dione (L), and four transition metal complexes were synthesized. The ligand and its complexes were characterized by IR, 1H and 13C-NMR spectra, elemental analyses, magnetic susceptibility, mass spectra, UV-Vis. and thermogravimetry-differential thermal analysis (TGA-DTA). The metal complexes showed different geometric structures. Antibacterial tests of the ligand and complexes were also done. The Zn(II) complexes showed antibacterial activity against Staphylococcus aureus ATCC-25923 at middle level. The optical properties of the ligand and its complexes were extensively investigated by optical measurements. The average transmittance value of the ligand was the highest value, while the average transmittance value of the [CuL2(NO3)2]·6H2O complex was the lowest value. The optical band gap of the ligand, [(Zn)2L(OH)4]·2DMF, [ZnL(NO3)2(H2O)2]·5H2O, [CuL2(OAc)]·OAc·3.5H2O and [CuL2(NO3)2]·6H2O complexes were calculated and 3.121 eV, 2.180 eV, 1.551 eV, 2.489 eV and 1.556 eV values were found, respectively. The complexes decreased the optical band gap of the ligand. The optical band gap value of the [ZnL(NO3)2(H2O)2]·5H2O complex is the lowest value. The optical band gap value of the ligand is the highest value. The complexes decrease the angle of incidence of the ligand, while complexes increase the angle of refraction of the ligand. The electric susceptibility of the ligand decreases with its complexes. © 2014, Sociedad Química de México
