If there is no the Standard Model Higgs boson, the interaction among the gauge bosons becomes strong at high energies (∼ 1TeV). The effects of strong electroweak symmetry breaking could manifest themselves indirectly through the vertices as anomalous gauge boson couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings κ...

We calculate the Coulomb effects on the cross section for e + e − → W + W − taking into account the instability of the W bosons. We carefully explain the consequences of instability throughout the energy range which will be accessible at LEP2. We present a formula which allows these effects to be easily implemented.

We study interference effects between resonant and nonresonant amplitudes for the γγ → W + W − process at a backscattered photon-photon collider. We show that a Higgs boson with M H > ∼ 200 GeV is manifest as a resonant dip in the W + W − invariant mass spectrum and we investigate its statistical significance. There has been recent interest in weak gauge boson pair production in γγ collisions a...

 Introduction: Nowadays, applications of free-lead radiation shields are increased specially for weighting factor and toxicity of lead elements. Although touching the lead may be results in the nervousand blood system of body, it is not exactly proven yet. Protective measures are the fundamental parts of radiation protection. On the other hand, high weighting factor of lead sh...

A topical o/w cream containing tretinoin microspheres was prepared. Gelatin microspheres of tretinoin were prepared using coacervation method. These microspheres contained about 50% w/w tretinoin. The particle size range of microspheres was between 90-150 m m. In vitro drug release from microspheres and a cream formulation was studied. It was shown that drug release from microspheres followed H...

In this work, an interatomic potential for the beryllium-tungsten system is derived. It is the final piece of a potential puzzle, now containing all possible interactions between the fusion reactor materials beryllium, tungsten and carbon as well as the plasma hydrogen isotopes. The potential is suitable for plasma-wall interaction simulations and can describe the intermetallic Be(2)W and Be(12...

b ac k gr o und: w o lbachia pipientis is maternally inherited endoparasitic bacterium belonging to the α-proteobacteria, infecting 20–75% of all insect species including sand flies. the wolbachia surface protein ( wsp ) was employed as an appropriate marker for strain typing. the objective of our research was to find the possibility of detection of w. p ipientis in phlebotomus perfiliewi trans...

In a recent paper, the authors have shown that the secondary reduction of W-algebras provides a natural framework for the linearization of W-algebras. In particular, it allows in a very simple way the calculation of the linear algebra W(G, H) ≥0 associated to a wide class of W(G,H) algebras, as well as the expression of the W generators of W(G,H) in terms of the generators of W(G, H) ≥0. In thi...

Bentonite bleaching earth is utilized for purifying used motor oil through a recovery process in order to improve the quality and stability of the final product. Indeed, spent bleaching earth is generated due to adsorbing oil impurities. Polluted spent bleaching earth contains 20-40% (w/w) oil and is flammable. Its disposal without pre-treatment leads to loss of oil along with environmental imp...

ni-w coatings, compared to pure nanocrystalline ni, exhibit higher hardness and wear resistance. in some cases, these coatings are considered as environmental friendly alternatives for hard chromium coating. till now, most of ni-w coatings have been produced by direct current electrodeposition from alkaline baths. in this study square pulse current was used for deposition of ni-w precipitates f...
