in this article‎, ‎we have characterized ideals in $c(x)$ in which‎ ‎every ideal is also an ideal (a $z$-ideal) of $c(x)$‎. ‎motivated by‎ ‎this characterization‎, ‎we observe that $c_infty(x)$ is a regular‎ ‎ring if and only if every open locally compact $sigma$-compact‎ ‎subset of $x$ is finite‎. ‎concerning prime ideals‎, ‎it is shown that‎ ‎the sum of every two prime (semiprime) ideals of e...

conclusions managing such patients needs a proper transport facility, proper care during transport, appropriate evaluation in the hospital and prompt conservative or operative treatment. treatment is usually safe and effective by well trained professionals with good clinical and radiological outcomes. patients and methods thirty patients (22 males, 8 females) with upper cervical spine injuries ...

background and objectives: toxoplasma gondii is an obligatory intracellular parasite which causes severe diseases in the fetus of pregnant women and immunocopmromised patients. serological tests based on recombinant protein are one of the main diagnosis methods for the detection of specific antibodies in serum samples. dense granule antigenic proteins derived from t. gondii (tggras) are potenti...

‎for the subclasses ${mathcal m}_1$ and ${mathcal m}_2$ of‎‎monomorphisms in a concrete category $mathcal c$‎, ‎if ${mathcal‎‎m}_2subseteq {mathcal m}_1$‎, ‎then ${mathcal m}_1$-injectivity‎‎implies ${mathcal m}_2$-injectivity‎. ‎the baer type criterion is about‎ ‎the converse of this fact‎. ‎in this paper‎, ‎we apply injectivity to the classes of {it $c$-dense‎, ‎$c$-closed}‎ ‎monomorphisms‎. ...
