background : toxoplasmosis is a worldwide endemic disease. in congenitally infected infants and aids patients, toxoplasmosis causes high rates of morbidity and mortality. in these cases antibody detection is difficult; so detection of parasite or its components could be useful tool for early detection and following treatment of the infection. methods : sixty-three balb/c mice were injected intr...

There are many professional vocabularies in electrical enterprises, and existing analyzer could not fulfill the application when constructing the search engine for electrical enterprises. In this article, we take the operation system of electrical enterprises as the background, and put forward a sort of word segmentation algorithm based on the implementation of vocabulary in order to design the...

and Hajnal [I] introduced the real function f(a) =inf {.P(G) J ~~i~: ~a}. They asked about the behaviour ofj(rx) as rx tends to infinity. The complete bipartite graph Kn,n shows that f(n)~c ·log n for n~2, but originally it was unknown whether f(a) is bouJ1ded or not. Recently Gyarfas, Koml6s and Szemeredi (2] showed that f(a) ~a ·log a, provided that a>b, where a and bare suitable contants. Ob...

1. INTRODUCTION. For primes that can be written as a sum of integer squares, p = a 2 + (2b) 2 , Kaplansky [4] asked whether the binary quadratic form F = x 2 − py 2 always represents a and 4b (that is, are there integer solutions to x 2 − py 2 = a and x 2 − py 2 = 4b). Feit [1] and Mollin [4] proved that F does always represent a and 4b using the theory of ideals and the class group structure o...

We give necessary and sufficient conditions for a Banach space operator with the single valued extension property (SVEP) to satisfy Weyl’s theorem and a-Weyl’s theorem. We show that if T or T ∗ has SVEP and T is transaloid, then Weyl’s theorem holds for f(T ) for every f ∈ H(σ(T )). When T ∗ has SVEP, T is transaloid and T is a-isoloid, then a-Weyl’s theorem holds for f(T ) for every f ∈ H(σ(T ...

We study the farthest point mapping in a p-normed space X in virtue of subdifferential of rx sup{{x − z p : z ∈ M}, where M is a weakly sequentially compact subset of X. We show that the set of all points in X which have farthest point in M contains a dense G δ subset of X.
