It is shown that if the maximal ideal space Δ(A) of a semisimple commutative complete metrizable locally convex algebra contains no isolated points, then every compact multiplies is trivial. In particular, compact multipliers on semisimple commutative Fréchet algebras whose maximal ideal space has no isolated points are identically zero.

Abstract  

Transport of uranyl ions through liquid membranes consisting of tri-n-butylphosphate (TBP) in kerosene oil supported in Celgard 2400 polypropylene microporous film has been studied. Various parameters, such as the effect of nitric acid concentration in the feed solution, TBP concentration in the organic membrane phase, stripping agent concentration and temperature on the flux of uranium across the liquid membrane, have been investigated. The results obtained have been used to elucidate the mechanism of uranium transport and stoichiometry of the diffusing species.

Hepatitis B virus (HBV) transmission via blood and other body fluids from infected individuals to healthy people has been largely demonstrated. However, in the current literature, there is little information available on the potential role of cerumen in HBV transmission.Cerumen and blood were collected from 70 patients infected with HBV and 70 volunteer healthy people were selected as the control group, and the samples were evaluated by ELISA and Real-time PCR.All the patients proved positive for HBsAg and anti HBc total. Sixty-one of the 70 cerumen samples of cases (82.1%) and 5 (7%) of controls were positive for HBV DNA with ranges from 1.53 × 102 to 2.9 × 108 and 1.3 × 102–2.6 × 105/ml, respectively. In three patients, the level of HBV DNA in cerumen was higher than that in the serums. The patients who were positive for HBeAg showed a higher rate of HBVDNA in the serum and cerumen.The results of this study showed the level of HBV DNA as a probably indicator of high risk transmission factor, which was present in the cerumen of chronic hepatitis B patients in west of Iran.
