An arrangement of pseudocircles is a finite collection of Jordan curves in the plane with the additional properties that (i) every two curves meet in at most two points; and (ii) if two curves meet in a point p, then they cross at p. We say that two arrangements C = (c1, . . . , cn) and D = (d1, . . . , dn) are equivalent if there is a homeomorphism φ of the plane onto itself such that φ[ci] = ...

We prove that for any finite real hyperplane arrangement the average projection volumes of the maximal cones are given by the coefficients of the characteristic polynomial of the arrangement. This settles the conjecture of Drton and Klivans that this held for all finite real reflection arrangements. The methods used are geometric and combinatorial. As a consequence we determine that the angle s...

background: hundreds of patient education materials i.e. pamphlets are annually published in healthcare systems following their design, correction, and revision. aim: to design and evaluate patient education pamphlets based on readability indexes and their comparison with literacy level in society. method: the average literacy level among 500 patients admitted to two training hospitals in bojnu...

PURPOSE/OBJECTIVES To review selected empirical literature examining outcomes of advanced practice nursing with a specific focus on the work of oncology advanced practice nurses (APNs). DATA SOURCES Published articles (descriptive and data-based) and books. DATA SYNTHESIS Well-designed, methodologically sound investigations offer clear and compelling evidence that APNs are effective in impr...

The purpose of this study was to analyze tasks performed by nurses at hospitalization units (maternity, general medicine, surgical and pediatric) in a training hospital in order to better know which factors make it difficult to outline their role as well as the meaning of their actions. It's a descriptive-type qualitative research. Twenty nurses were interviewed following a half-structured scri...

The purpose of the project was to capture nursing data and knowledge, represent it for use and re-use by retrieval from a data warehouse, which contains both clinical and financial hospital data. Today nurses at LUH use standardized nursing terminologies to document information related to patients and the nursing care in the EHR at all times. Pre-defined order sets for nursing care have been de...

“A multidisciplinary approach to postoperative care involving the surgical team is required to improve the overall management of surgical wounds.” Surgery is one of the most important treatments offered by today’s NHS. As a result, the care delivered to patients in the pre-operative, intra-operative and postoperative stages form one of the cornerstones of nursing care. This article provides an ...
