We study the effects of a possible strong final state interaction among longitudinal W 's in γγ → W W. The relevant partial wave amplitudes are modified by an Omnès function approximated by a Breit-Wigner form factor. We study the fractional cross section f 00 = σ LL /σ Total with both W 's longitudinally polarised, in the presence of a J = 2 resonance (M = 2.5 TeV, Γ = 500 GeV) or a J = 0 reso...

The current non-linear programming method does not derive regional economic surpluses and may derive an imprecise maximized value of the total economic surplus. The main reason is that the integrals for supply functions will automatically take regional non-economic producer surpluses into account if any intercepts of supply functions is negative. Consequently, the derived values are always lowe...

If the balance between availability and requirement drives the value, then the economic value of water in agriculture should be remarkably higher in water-scarce regions when compared to water-rich regions. Similarly, in water-abundant regions, if the land is scarce, then the incremental return per unit of land should be higher than that in land-rich region that are water-scarce. These hypothes...

In this work we report on a next-to-leading order calculation of WW + jet production at hadron colliders, with subsequent leptonic decays of the W -bosons included. The calculation of the one-loop contributions is performed using generalized unitarity methods in order to derive analytic expressions for the relevant amplitudes. These amplitudes have been implemented in the parton-level Monte Car...

The concept Time Value of Money states that the value money today is more valuable than same in future. But sharia principles there no such thing as Money. In principles, it better known Economic Time, meaning actually has time value, but economic value. Then itself triggers human desire to develop their various ways, one which property investment. purpose this study answer how investment schem...

Although China has made dramatic economic progress in recent years, air pollution continues to be the most visible environmental problem and imposes significant health and economic costs on society. Using data on pollutant concentration and population for 2003, this paper estimates the economic costs of health related effects due to particulate air pollution in urban areas of Tianjin, China. Ex...

The ecosystem service concept is becoming more and more acknowledged in science and decision-making. Taking an economic valuation approach, we quantified the economic value change of ecosystem services for different land use types in the middle basin of Heihe River, Northwest China. Eight ecosystem services indicators were selected: raw materials production, crop production, gas regulation, hyd...

the purpose of the present study is to investigate the relationship between intellectual capital (human capital efficiency, customer capital efficiency, and structural capital efficiency) and economic value added of the listed companies on the tehran stock exchange (tse). the population includes 39 firms selected through systematic sampling. the data is collected from the audited financial stat...

abstract since about 34% of areas under rice cultivation in whole country is attributed to gilan; in this study we pay attention to some economical dimensions, especially economic values of inputs in this region. data were collected from 80 rice producers in 2007-2008. consider to importance the parametric approach in production structure and factors demand, applying seemingly unrelated regress...
