medication errors account for about 78% of serious medical errors in intensive care unit (icu). so far no study has been performed in iran to evaluate all type of possible medication errors in icu. therefore the objective of this study was to reveal the frequency, type and consequences of all type of errors in an icu of a large teaching hospital. the prospective observational study was conducte...

We prove that there is a universal measure on the unit circle such that any probability measure on the unit disk is the limit distribution of some subsequence of the corresponding orthogonal polynomials. This follows from an extension of a result of Alfaro and Vigil (which answered a question of P. Turán): namely, for n < N , one can freely prescribe the n-th polynomial and N − n zeros of the N...

Let T be the unit circle on R. Denote by BMO(T) the classical BMO space and denote by BMOD(T) the usual dyadic BMO space on T. Then, for suitably chosen δ ∈ R, we have ‖φ‖BMO(T) ⋍ ‖φ‖BMOD(T) + ‖φ(· − 2δπ)‖BMOD(T) ,∀φ ∈ BMO(T) To cite this article: C. R. Acad. Sci. Paris, Ser. I 336 (2003).

A new positive-unit theorem-proving procedure for equational Horn clauses is presented. It uses a term ordering to restrict paxamodulation to potentially maximal sides of equations. Completeness is shown using proof orderings. 1. I n t r o d u c t i o n A conditional equation is a universally-quantified Horn clause in which the only predicate symbol is equality. We write such a clause in the fo...

We give a combinatorial interpretation for the mixed volumes of two adjacent slices from the unit cube in terms of a refinement of the Eulerian numbers. 1998 Academic Press Let C d denote the d-dimensional unit cube, that is, C d =[x # R d : 0x i 1]. All the volumes and mixed volumes which appear in this note will be normalized so that the volume of C d is given by V(C d)=d!. We consider slices...

Let p be a trigonometric polynomial, nonnegative on the unit circle T. We say that a measure σ on T belongs to the polynomial Szeg˝ o class, if dσ(e iθ) = σ ′ ac (e iθ) dθ + dσ s (e iθ), σ s is singular, and 2π 0 p(e iθ) log σ ′ ac (e iθ) dθ > −∞ For the associated orthogonal polynomials {ϕ n }, we obtain pointwise asymp-totics inside the unit disc D. Then we show that this asymptotics holds in...

We examine densely defined (but possibly unbounded) multiplication operators in Hilbert function spaces possessing a complete Nevanlinna–Pick (CNP) kernel. For such operator T, the domains of T and \(T^*\) are reproducing kernel contractively contained ambient space. study several aspects these spaces, especially domain \(T^*\), which can be viewed as analogs classical deBranges–Rovnyak unit di...
