It has been argued long ago that ηb could be observed through the ηb → J/ψ(→ μ+μ−)J/ψ(→ μ+μ−) decay chain. Recent calculations indicate that the width of ηb into two J/ψ is almost three order of magnitude smaller than the one into the DD. We study the effects of final state interactions due to the DD intermediate state on the J/ψ J/ψ final state. We find that the inclusion of this contribution ...

Poly(butylene adipate-co-terephthalate) (PBAT) and poly(butylene succinate-co-adipate) (PBSA) blend films were prepared with different contents of a multifunctional epoxide chain extender Joncryl ADR-4468 (ADR) or benzoyl peroxide (BPO). The long-chain-branching (LCB) introduced by ADR branched/crosslinked entanglement induced BPO increased melt elasticity, viscosity compatibility, as indicated...

Slowly digestible starches have received interest due to their lower increase of postprandial blood glucose and insulin levels and, hence, modification towards slower digestibility has commercial interest. However, chemical characteristics driving enzymatic (digestive) degradation are not fully unraveled. The digestion properties been linked crystalline type, chain length distribution, amylose ...

Side-chain engineering is an important strategy in designing novel polymer semiconductor materials for high-efficient organic solar cells. The use of trialkylsilyl side chains can improve the photovoltaic efficiency by decreasing energy HOMO and improving its crystallinity hole mobility. Compared to simple linear derivatives, α-branching alkyl groups causes strong aggregation excessive phase se...

The b → s ll process is studied in the minimal supergravity model in detail. Taking account of the long distance contributions from the cc resonances, we calculate the branching ratio and the lepton forward-backward asymmetry in this model. We find that there is a strong correlation between the branching ratios of b → s γ and b → s ll processes and that the interference effect can change the b ...

Abstract Polyamide 6 (PA6) was modified with ethylene maleic anhydride syndiotactic copolymer resin (ZeMac), and triglycidyl isocyanurate (TGIC) as modifiers to prepare a grafting structure long-chain branching structure, respectively. The effects of two on the rheological behavior, crystallization properties, foaming performance, mechanical properties PA6 were systematically studied by rotatin...

this paper presents a case-report of cutaneous actinomycosis due to actinomyces viscosus in a 22 year old man, hospital staff from tehran with multiple fistulous tracts in his right hand and a history of skin injury due to thorn of plant. diagnosis was based on the observation of gram positive coccoid, diphtheroid and long branching filaments in direct examination of pus from fistulous tracts a...
