the effects of soil tillage methods and residue management were studied at miandoab agriculure station during 2003-2005. the experiment design was split block with the main plots devoted to residual management strategies (burning residue, crushing residue by disk, no treatment). subplots were tillage methods (moldboard plowing to 20-25 cm in fall, moldboard plowing to 20-25 cm in spring, moldbo...

The one loop corrected effective Lagrangian for the quark-squark-chargino and quarksquark-neutralino interactions is computed. The effective Lagrangian takes into account the loop corrections arising from the exchange of the gluinos, charginos, neutralinos, W, Z, the charged Higgs, and the neutral Higgs. We further analyze the squark decays into charginos and neutralinos and discuss the effect ...

A recently proposed scaling law for the decay time of alpha particles is generalized for cluster decay. It is shown that for the decay of even-even parents, logT1/2 depends linearly on the scaling variable S=(ZcZd) 0.6/ √ Qc and on the square root of the reduced mass of cluster and daughter. PACS numbers: 23.90.+w,25.85.Ca,23.60.+e

If the fourth generation fermions exist, the new quarks could influence the branching ratio of the rare B → K * ν ¯ ν decay. Two possible solutions of the fourth generation CKM factor (V * ´ ts V ´ tb) (±) are obtained as a function of the new´t-quark mass (m ´ t) from the experimental results of the B → X s γ together with the semileptonic decay B → X c ℓ¯ ν. The branching ratio of the decay B...

The total measurable level of a pathogen is due to many sources, which produce a variety of pulses, overlapping in time, that rise suddenly and then decay. What is measured is the level of the total contribution of the sources at a given time. But since we are only capable of measuring the total level above some threshold x0, we would like to predict the distribution below this level. Our princ...

We study the bound states of brane/antibrane systems by examining the motion of a probe antibrane moving in the background fields of N source branes. The classical system resembles the point-particle central force problem, and the orbits can be solved by quadrature. Generically the antibrane has orbits which are not closed on themselves. An important special case occurs for some Dp-branes movin...

Schlatter The Bs –B 0 s oscillation frequency ms is measured with 36 pb −1 of data collected in pp collisions at √ s = 7 TeV by the LHCb experiment at the Large Hadron Collider. A total of 1381 Bs → D−s π+ and Bs → D−s π+π−π+ signal decays...

This suggestion of the author was shown to be accessible in KTeV because even though there was no charged particle vertex, the π decay into two gammas and the high precision electronmagnetic calorimeter permits the vertex to be precisely measured by constraining to the π mass [8]. This along with the high flux of Ξ hyperons in the experiment permitted these analysis. Hyperon semi-leptonic decay...
