The goal of this study was to explain various measurements of atmospheric methane on Mars performed by the PFS instrument on-board the European Mars Express mission and from ground based observations. In order to reach this goal a layer of methane was assumed to exist in porous near surface layers of …

The observed persistent soft X-ray spectra (0.5 - 10 keV) of anomalous Xray pulsars (AXPs) can be explained by the magnetar model (Woods and Thompson et al., 2002 [3]) where the emission is powered by the decay of an extreme high magnetic eld ( 1014 G). Because these spectra are relatively soft, measurements …

At ageing, there comes a certain point when people are no longer able to live independently in their own homes. With an ever increasing elderly population, this constitutes a significant and increasing burden for the health care expenses. The need for more cost effective solutions is evident. Research …

Societal developments show that future demands for visualization can be expected to grow. In many areas of organized human activities organizations may turn away from textual and numerical flatlands, and rely on the convenient and multidimensional digital worlds. Virtual worlds for facility management, …

The worldwide obesity epidemic is a major and complex problem, resulting from the interaction of individual metabolic, genetic, and psychological factors with meso- and macro environmental factors. Adolescents, with their rapid changes in body composition, together with their shift in orientation from …

Carpal tunnel syndrome (CTS) is the most commonly diagnosed peripheral neuropathy due to entrapment. This syndrome is currently being diagnosed clinically, often confirmed through the use of neural conductivity studies (NCS). Over 25 percent of the cases are still missed using this method, while NCS …

In this paper validity and compatibility of the SAM and KLD screening instruments are the central themes. A screening instrument can be called valid if it identifies performance that is important to society. A screening instrument is called compatible if these instruments can be used interchangeably. …
