The Medicare ESRD program is designed to assure qualifying beneficiaries access to high quality, costeffective medical care. To a large extent, it has succeeded. Today, over 90 percent of all patients being treated for ESRD ultimately receive some Medicare reimbursement. This report discusses the growth in the number of participating renal facilities furnishing some form of ESRD treatment. (See...

This paper argues that it can give good results to use bad and good design examples when teaching Human-Computer Interaction provided that the examples are elaborated by the teacher in a manner that enables a changed (shaken) mind-set in the students. In the paper examples from lectures, exercises and larger assignments using concrete material as a base, are discussed from the perspective of ge...

This note is intended to address one particular issue in the relative status of Quantum Chemistry in comparison to both Chemistry and Physics. It has been suggested, in the context of the question of the reduction relations between Chemistry and Physics that Quantum Chemistry as a research programme is incapable of furnishing useful guidance to practising chemists. If true, this claim will let ...

The rapid development of high brightness light emitting diodes (LEDs) has triggered many applications, especially in the area of display lighting. This paper focuses on the application of white LEDs in refrigerated display cases. The fluorescent lighting presently used in commercial refrigerators is inefficient in the application and also it provides poor lighting for merchandising. A laborator...

background : some characteristics of lighting sources such as color properties and ultraviolet emissions have important roles on visual and non-visual health effects of lighting. this study aimed to investigate the light emissions of some compact fluorescent lamps (cfls) and incandescent lamps commercially available to the iranian consumers. methods: sixty lamps included 48 single envelope cfls...

Lighting design in computer graphics is essentially not a random process but one driven by both a technical and aesthetic appreciation of lighting. In some applications, the result of the lighting design process is a 2D image derived by rendering a 3D scene. Users with limited understandings of manipulation of lighting parameters may have difficulties in properly modifying the lighting paramete...
