potato virus y (pvy) and potato leafroll virus (plrv) are two major viruses which reduce 10-90 percent of yield and quality of potato tubers. in the present study, the efficiency of different methods, including meristem culture, thermotherapy followed by meristem culture and electerotherapy followed by meristem culture in two cultivars (agria and marfona) infected by plrv or pvy were evaluated....

We measured the rate of elimination of phenylalanine by constant intravenous infusion of L-phenylalanine in 14 parents of children with phenylketonuria and in 21 subjects with a negative family history for this disease. When reciprocals of the observed elimination rates were plotted against the reciprocals of the increase in the plasma phenylalanine concentrations, approximately straight lines ...

We prove a central limit theorem for the nite dimensional marginals of the Gibbs distribution of the macroscopicòverlap'-parameters in the Hoppeld model in the case where the number of random`patterns', M, as a function of the system size N satisses lim N"1 M(N)=N = 0, without any assumptions on the speed of convergence. The covariance matrix of the limiting gaussian distributions is diagonal a...
