Irradiation of polymers is one of the most effective and economical methods for modifying their properties and for changing their applications. In this study, an extrusion grade polypropylene (PP) was treated by electron beam irradiation to produce a PP suitable for injection molding. Irradiation was carried out at different doses (0-80 kGy) under atmosphere air and at ambient temperature. Melt...

Resonance Raman spectra of the ferrous CO complex of cytochrome P-450cam have been observed both in its camphor-bound and free states. Upon excitation at 457.9 nm, near the absorption maximum of the Soret band, the ferrous CO complex of the camphor-bound enzyme showed an anomalously intense Raman line at 481 cm-1 besides the strong Raman lines at 1366 and 674 cm-1 for the porphyrin vibrations. ...

In light of the recent data from BES collaboration for χc0 → V V , PP and SS, and from CLEO-c for ηη, η′η′ and ηη′, we present a detailed analysis of the decays of heavy quarkonia into light meson pairs such as χc0,2 → V V , PP and SS in a recently proposed parametrization scheme. An overall agreement with the data is achieved in χc0,2 → V V and PP , while in χc0 → SS we find that a possible ex...
