Polyphenol oxidase (PPO) activity varied in differentiation from hyphae to rhizomorph and croute in A. mellea. In undifferentiated hyphae there was not any PPO activity, while croute showed the highest activity. Electrophoresis in the presence of SDS allows the detection of intensive enzyme forms of PPO, and can also convert slower migrating enzyme forms to faster ones. Some fluorescent co...

â â â â â â  â  abstract â  outward-oriented economies seem to grow faster than inward-looking ones. does the literature on convergence have anything to say on this? in the dynamic heckscher-ohlin-samuelson model, with factor-price equalization, there is no convergence of incomes. this is because with identical preferences and return to capital, irrespective of initial levels the growth rates o...

Recent measurements on electron neutrinos suggest that they might have an imaginary rest mass. This paper shows that they have a possibility being emitted from the atomic nucleus as a faster-than-light (FTL) particle called a tachyon.

Microbial fuel cell (MFC) mathematical model was established with suspended microorganisms, biomass on the electrode material, soluble chemical substrates and intermediary. By simulating the process of the substrate degradation, biomass growth and the electric current production process, With different initial biomass concentration, suspended microbial biomass and biomass attaching on electrode...
