In the present paper we consider compound Poisson approximation by Stein's method for dissociated random variables. We present some applications to problems in system reliability such as k-runs, counting isolated vertices in the rectangle lattice on the torus as well as consecutive 2-systems, coloured graphs, birthday problems, connected s-systems and two(More)
The purpose of the present study was to examine the impact of the congenital absence of one hand on cortical organization of the sensorimotor cortex (S1/M1). We investigated the tongue representation in S1/M1 in nine participants with normally developed limbs, comprising the control group, and in eight persons with a congenitally completely missing hand(More)
Multiple databases provide ratings of drug-drug interactions. The ratings are often based on different criteria and lack background information on the decision making process. User acceptance of rating systems could be improved by providing a transparent decision path for each category. We rated 200 randomly selected potential drug-drug interactions by a(More)
Aims of the study were (1) to establish a method for quantification of chlorhexidine (CHX) in small volumes and (2) to determine CHX release from differently concentrated CHX-containing preparations, varnishes, and a CHX gel applied on artificial fissures. CHX determination was conducted in a microplate reader using polystyrene wells. The reduced intensity(More)
In prosthetic dentistry, double crown systems have proved their suitability as retainers for removable partial dentures. However, investigations in this context, regarding polyetheretherketone, are scarce. Therefore, the aim of this study was to test the retention force (RF) between polyetheretherketone (PEEK) primary and cobalt-chromium (CoCr), zirconia(More)
The aim of this work was to evaluate the influence of specimen preparation and test method on the flexural strength results of monolithic zirconia. Different monolithic zirconia materials) were tested with three different methods: 3-point, 4-point, and biaxial flexural strength. Additionally, different specimen preparation methods were applied: either dry(More)
This study investigated the colorimetric properties of different veneering materials on core materials. Standardized specimens (10 mmˆ10 mmˆ1.5 mm) reflecting four core (polyetheretherketone (PEEK), zirconia (ZrO 2), cobalt–chromium–molybdenum alloy (CoCrMo), and titanium oxide (TiO 2); thickness: 1.5 mm) and veneering materials (VITA Mark II, IPS e.max(More)
BACKGROUND The well-being of breast cancer patients and reporting of adverse events require close monitoring. Mobile apps allow continuous recording of disease- and medication-related symptoms in patients undergoing chemotherapy. OBJECTIVE The aim of the study was to evaluate the effects of a mobile app on patient-reported daily functional activity in a(More)
Zirconia as a restoration dental material are gaining attention because of their high mechanical properties and good biocompatibility. Therefore, investigation of the flexural strength of zirconia is of great interest. For this purpose, Weibull statistics for description of the material reliability are frequently used. The aim of this work was to present a(More)
