The present paper examines the energy absorption capacity of concrete-filled steel tube slender (CFTS) columns having different aspect ratios. CFTS are nonlinearly analysed employing finite element software ABAQUS. In order to validate simulation columns, an experimentally tested column is simulated and its achieved result compared with that column. Since it concluded there a good agreement bet...
The partitioning of turbulent perturbations into a ‘‘low-dimensional’’ active part responsible for much of the turbulent energy and fluxes and a ‘‘high-dimensional’’ passive part that contributes little to turbulent energy and transport dynamics is investigated using atmospheric surface-layer (ASL) measurements. It is shown that such a partitioning scheme can be achieved by transforming the ASL...
We consider the low-energy signatures of, and high-energy motivations for, scenarios of semi-perturbative gauge coupling unification. Such scenarios can leave striking imprints on the low-energy sparticle spectrum, including novel gaugino mass ratios (including M2/M1 ≈ 1), substantial compression of the intra-generational squark-to-slepton mass ratios, and an overall lifting of scalar masses re...
Two experiments were conducted to investigate the effect of dietary energy levels on the performance of Arian broiler chicks. Trial 1 was performed in summer and trial 2 in fall. Both experiments were accomplished in 5×2 factorial designs, involving 5 levels of dietary metabolizable energy and two sexes. Each of the 10 resulting treatments was replicated 4 and 3 times in trials 1 and 2, respect...
We develop theory leading to an ability to catalog types of elementary particles. The resulting catalog provides for known interaction-mediating bosons, non-traditional interactioncarrying bosons, and fermions. Ratios of theoretical numbers of analogs of various types of particles match observed ratios of densities for baryonic matter, dark matter, and dark energy.

In this research, water equivalent ratios (WER) at helium ion beam energy ranging 25-250 MeV/u for four potential plastic dosimetric materials: polycarbonate (PC), polypropylene (PP), polymethyl methacrylate (PMMA), and paraffin have been calculated using MCNPX Monte Carlo code. Among studied materials, PC and PP with 0.979 and 1.177 show minimum and maximum differences with water respectively....
We discuss the final results of the MACRO experiment on atmospheric neutrino oscillations. The data concern event topologies with average neutrino energies of ∼ 3 and ∼ 50 GeV. Multiple Coulomb Scattering of the high energy muons was used to estimate the neutrino energy event by event. The angular distributions, the L/Eν distribution, the particle ratios and the absolute fluxes all favor νμ → ν...
Ab initio calculations are presented for the vibrational branching ratios in three-photon resonant fourphoton ionization of H2 via the C 1ITu state. Energy and internuclear distance dependences of the boundfree electronic transition .matrix element are explicitly included to estimate deviations from the FranckCondon approximation. While our calculated branching ratios confirm certain important ...
