There are two reasons for s tudying the possible role of the Epstein-Barr virus (EBV) in relation to rheumato id arthritis (RA). The first is the recent demonstrat ion by Alspaugh and co-workers that EBV infection o f normal peripheral blood lymphocytes induces the development in these cells of a nuclear antigen against which most patients with RA have precipitat ing antibodies (I). The second ...

A two-dimensional balance model of populations distributed by property was developed using the ordinates of particle diameter andparticle density. This model makes it possible to calculate the spectrums of granulation changing over time in the fluidized bed duringbatch operation and in addition to calculate the time-dependent size distribution of the product granulate for continuous...
متن کاملAsymptotic behavior of alternative Jensen and Jensen type functional equations
In 1941 D.H. Hyers solved the well-known Ulam stability problem for linear mappings. In 1951 D.G. Bourgin was the second author to treat the Ulam problem for additive mappings. In 1982–2005 we established the Hyers–Ulam stability for the Ulam problem of linear and nonlinear mappings. In 1998 S.-M. Jung and in 2002–2005 the authors of this paper investigated the Hyers–Ulam stability of additive ...
