We study the electromagnetic form factors of lowest-lying singly heavy baryons in a pion mean-field approach, which is also known as SU(3) chiral quark-soliton model. In limit heavy-quark mass, dynamics inside baryon governed by $N_c-1$ valence quarks, while quark remains mere static color source. this framework, described combining colored soliton with quark. infinitely mass limit, we can comp...

The history of jazzing the theme variations from Allegretto Beethoven’s Seventh Symphony began with a revision its four-measure fragment in vein light-popular style and traversed path towards deep transformation, which all likelihood would be quite congenial to composer original work, as 50-minute variation cycle. article discusses three jazz revisions – potpourri Beethoven Wrote It... But It S...

Pristine graphene is a semimetal and thus does not have a band gap. By making a nanometer scale periodic array of holes in the graphene sheet a band gap may form; the size of the gap is controllable by adjusting the parameters of the lattice. The hole diameter, hole geometry, lattice geometry, and the separation of the holes are parameters that all play an important role in determining the size...

Abstract A billet is a bar made from crude steel which surface contains scales are rich in iron oxides. This study presents the carbothermal reduction of formed billets. The process included reaction oxides contents with carbon (in ratio 5:1) and annealing tubular furnace under argon atmosphere. occurred reactions discussed using thermodynamic calculations thermal analysis indicate three-stage ...

background: diabetic patients have a higher prevalence of non-dipping pattern in blood pressure (bp) than general population. non-dipping arterial pressure pattern is associated with increased cardiovascular risk. the objective of this study was to investigate the association between the clinical and paraclinical characteristics of the diabetic patients with circadian bp variability. m aterials...

The potential energy surfaces of low-lying states in rhenium tetrahydride (ReH(4)) were explored by using the multiconfiguration self-consistent field (MCSCF) method together with the SBKJC effective core potentials and the associated basis sets augmented by a set of f functions on rhenium atom and by a set of p functions on hydrogen atoms, followed by spin-orbit coupling (SOC) calculations to ...

Between the new physics candidates proposed to explain the tt̄ asymmetry measured in the Tevatron, there are some scalar diquarks with electric charge +4/3. This kind of diquark is also needed to classify all the scalars of the supersymmetric standard model, with three generations, under a global flavour symmetry. One of the measurements that have caused some stir during the last run of the Teva...

introduction : the purpose of this study was to examine and compare the social adjustment in balanced and non-balanced patterns of the parent-child relationship.  methods : the research population was all female gifted students in the farzanegan high school in the first educational district of tehran in 2013-14. the sample research included 96 female gifted students who answered the parent-chil...
