Let S be a set of n points in d-space, no i + 1 points on a common (i − 1)-flat for 1 ≤ i ≤ d. An oriented (d − 1)-simplex spanned by d points in S is called jfacet of S, if there are exactly j points from S on the positive side of its affine hull. We show: (*) For j ≤ n/2 − 2, the total number of (≤ j)-facets (i.e. the number of i-facets with 0 ≤ i ≤ j) in 3-space is maximized in convex positi...

We have assessed the technical performance and robustness of NycoCard CRP Whole Blood, a near-patient test for C-reactive protein (CRP), when used in realistic daily routine situations in general practice clinics (GPC). Thirteen GPCs participated, five of them with technician staff. From 898 patients, split-sample measurements for CRP were made. Results from GPCs were compared with results from...

Occupational noise is unavoidably produced from dental equipment, building facilities, and human voices in the dental environment. The purpose of this study was to investigate the effect of occupational noise exposure on the dental professionals' health condition. The psychoacoustics approach noise exposure assessment followed by the health risk assessment was carried on at the paediatric denti...

An isometric folding is a non-expansive locally isometry that sends piecewise geodesic segments into piecewise geodesic segments of the same length. An isometric folding is a continuous map that need not to be differentiable. The points where it is not differentiable are called singular points. The foundations of isometric foldings of Riemannian manifolds are introduced by Robertson (1977). For...

OBJECTIVES We investigated the determinants of disparities in the regional density of private dentists in Austria. Specifically, we focused on the relationship between the density of private dentists and their public counterparts, thereby controlling for other possible covariates of dentist density. METHODS Dentist density was measured at the district level. We used panel data of dentist dens...

BACKGROUND Outpatients undergoing hemodialysis are at high risk for adverse drug events. Limited resources make it challenging for pharmacists to routinely obtain a best possible medication history (BPMH). OBJECTIVES The primary objective was to determine whether, for patients undergoing hemodialysis, a pharmacy technician has the skills to obtain a BPMH that would allow a pharmacist to ident...
