Article history: Received 30 September 2016 Accepted 30 September 2016 Available online 5 October 2016 had been referred to Loeys and Dietz since they clearly exhibited a syndromatic phenotype but did not fit other known aneurysm syndromes. Meanwhile the phenotype has broadened and it has been realized that e.g. a bifid uvula is not an essential feature in diagnosing LDS (Loeys et al., 2005). I...

With thousands of references to `Rietveld refinement' it is forgotten that the method did not suddenly appear in a flash of inspiration of a single person, but was the result of the work of three individuals working in the 1960s at the Reactor Centre Netherlands at Petten, Loopstra, van Laar and Rietveld. This paper outlines the origins of `profile refinement', as it was called at Petten, and a...

Sir: We read with interest the two papers by Drs van de Laar and van der Korst on food intolerance in rheumatoid arthritis (RA).1 2 It appears from this extensive but short study of patients with seropositive RA that rheumatoid disease in a small subgroup is sensitive to dietary manipulation. Identification of these patients is, however, a problem. We have previously shown that significant gut ...

The paper reports evidence that the multi-spin-axis magnetic structure proposed in 1964 by van Laar is realized antiferromagnetic CoO. This tetragonal spin arrangement produces both strong and weaker monoclinic distortion experimentally observed this material. to be a “monoclinic-like” of array oxygen atoms, comparable with rhombohedral-like atoms recently present NiO MnO. monoclinic-like has n...

Recently research into Brain-Computer Interfacing (BCI) applications for healthy users, such as games, has been initiated. But why would a healthy person use a still-unproven technology such as BCI for game interaction? BCI provides a combination of information and features that no other input modality can offer. But for general acceptance of this technology, usability and user experience will ...

In this study a simple and general chemical association theory is introduced. The concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. The theory is applied to derive the distribution function of associated species. As a severe test the application of presented theory to the van der Waals mixture model is introduced in order to p...
