This study evaluated the optical density of two microfilled and two microhybrid resins, as well as the composition of these materials with regard to their optical density. Cavities prepared in 12 2-mm- or 4-mm-thick acrylic plastic plates were filled with Z250 (3M-ESPE), A110 (3M-ESPE), Charisma (Heraeus-Kulzer) and DurafillVS (Heraeus-Kulzer). The resin increments (2-mm-thick) were light-cured...

Building large scale parallel applications mandates composition of independently developed modules that can co-exist and interact efficiently with each other. Several application frameworks have been proposed to alleviate this task. However, integrating components based on these frameworks is difficult and/or inefficient since they are not based on a common component model. In this thesis, we p...

Charisma is often seen as a positive leadership attribute, yet many studies give it a “mixed report card,” finding it less valuable than popularly thought. This paper develops a model to explain why. The key insight is that presenting the cold hard truth is often incompatible with simultaneously firing up followers—a tradeoff exists between information and inspiration; a temptation exists to hi...

This study evaluated weight loss and surface roughening after toothbrushing of different resin composites: one packable (Solitaire 2, Heraeus Kulzer), one microhybrid (Charisma, Heraeus Kulzer), one nanohybrid (Simile, Pentron) and one microfilled (Durafill VS, Heraeus Kulzer). Cylindrical specimens (n = 20) were prepared. Half of the samples were submitted to 60,000 strokes, at 4 Hz, with a de...

AIMS To develop a risk score to quantify bleeding risk in outpatients with or at risk of atherothrombosis. METHODS AND RESULTS We studied patients in the REACH Registry, a cohort of 68 236 patients with/at risk of atherothrombosis. The outcome of interest was serious bleeding (non-fatal haemorrhagic stroke or bleeding leading to hospitalization and transfusion) over 2 years. Risk factors for ...

This study tries to expand the understanding of the relationship between transformational leadership and organizational innovation at the organizational level. This research proposes a conceptual framework to explain the components of transformational leadership while focusing on the relationship between each component and organizational innovation. A sample of 219 managers from 63 companies in...

CHARISMA: The Antiplatelet Saga Continues To the Editor: We read with interest the Editorial by Norris and Barnett1 on the Clopidogrel for High Atherothrombotic Risk and Ischemic Stabilization, Management, and Avoidance (CHARISMA) trial. They conclude that aspirin is still the first choice in the secondary prevention of stroke, that clopidogrel is only marginally more effective than aspirin in ...
