We have considered a relativistically invariant quark coalescence model to predict hadronic resonance productions in heavy ion collisions. We extended our model-which has been applied earlier for strange and non-strange hadrons-to describe charmonium meson ratios, namely J/ψ, Ψ ′ and χ c , at RHIC energies. In the applied quark coalescence model the width of the produced mesons and resonances p...

The statistical bootstrap model is critically revised in order to include a medium-dependent resonance width in it. We show that a thermodynamic model with a vanishing width below the Hagedorn temperature TH and a Hagedorn spectrum-like width above TH may not only eliminate the divergence of the thermodynamic functions above TH , but also gives a satisfactory description the lattice quantum chr...

The cold-formed steel-framed shear wall sheathed with steel sheet is widely used as a lateral force-resisting system for light-framed construction. However, the boundary conditions of screw joint are not clear when screwed to frame. To address this issue, experimental methods have been calculate strength, but these many limiting factors. In study, we investigate structural performance integrate...

Methods to improve bearing capacity of footing resting of collapsing soil can, in fact, take two approaches, improving soil strength properties and intrusion of reinforcing sorces into soil. The footing is modeled by a square steel plate 0.1 by 0.1 m. The footing is loaded as to have a stress of 40 kPa and settlement is receded in dry and in soaking conditions. Two depths of the geo-mesh reinfo...

To elucidate the anatomical differences between patients with normal MCA bifurcations and those with bifurcations harboring MCA aneurysms, the analysis of three dimensional MRA or DSA were performed. Sixty two patients without intracranial lesions underwent three-dimensional MRA. The width of M2 branches and lateral angles, were measured. Then the DA ratios (width of larger M2/width of smaller ...

macrocyclops albidus and cyclops vicinus are the two important copepods living in hazar lake.for this study, 50 females for each species were collected. samples were taken between december 1999 andmarch 2000. length (pl), width (pw), and height (ph) of prosome and length (ul) and width (uw) ofurosome were measured in each female and subsequently, the following ratios pl/pw, pl/ph, pw/ph,pl/ul a...

Branching ratios for the decay of hadrons with large width or near thresholds depend on their definition. We test different definitions and show that rather branching can be obtained. For wide resonances sequential decays intermediate resonances, integration over spectral functions is mandatory. The tests are performed exploiting latest solution Bonn-Gatchina multi-channel analysis published va...
