In this paper, we first give a description of a surjective unit-preserving real-linear uniform isometry $ T : A longrightarrow B$,  where $ A $ and $ B $ are complex function spaces on compact Hausdorff spaces $ X $ and $ Y $, respectively, whenever ${rm ER}left (A, Xright ) = {rm Ch}left (A, Xright )$ and ${rm ER}left (B, Yright ) = {rm Ch}left (B, Yright )$. Next, we give a description of $ T...

suppose $pi:mathcal{a}rightarrow mathcal{b}$ is a surjective unital $ast$-homomorphism between c*-algebras $mathcal{a}$ and $mathcal{b}$, and $0leq aleq1$ with $ain  mathcal{a}$. we give a sufficient condition that ensures there is a proection $pin mathcal{a}$ such that $pi left( pright) =pi left( aright) $. an easy consequence is a result of [l. g. brown and g. k. pedersen, c*-algebras of real...

background and objective: due to contagiousness of pertussis, a rapid and sensitive method for diagnosis is required to initiate the treatment and interrupt its transmission. materials and methods: to detect b. pertussis strains, we used two real-time pcr targeting is 481 and bp283 sequences and compared factors influencing culture and real-time pcr results. results: totally, 779 specimens were...

Realist evaluation is a method increasingly adopted to provide an understanding of how and why program works, for whom, under what circumstances. Initial theories (IPT) are the crucial starting point any realist evaluation, however descriptions about they developed in practice remain under-reported published literature. This article argues value genuine research-group conversations using David ...
