Frei et al's 2012 review entitled "Authors' Perspective: What is the Optimum Intake of Vitamin C in Humans" is both flawed and misleading. RCTs are ill suited to determining the RDA, it is debatable that there is sufficient scientific evidence to determine the optimum intake of vitamin C in humans, observations regarding high-doses of ascorbate have been ignored, and there are inaccuracies of fact with respect to the saturation of blood plasma following low dose intake. Until the limitations of current knowledge are recognised it is unwise to set limits on the dose.

Currently shape grammars are designed for static models and applied in limited domains. They demand extensive user skills and cannot guarantee aesthetic results. Although the current approaches to shape grammar produce infinite designs the final designs lack context and harmony. The aim of this paper is to address the contextual and harmonisation issues in shape grammar by proposing a shape grammar framework inspired by the field of natural language processing. The new shape grammar framework make use of the four levels of analysis namely lexical, syntactic, semantic, and pragmatic levels, to enhance the overall design process. In satisfying these semantically and pragmatically well-formed constraints, the generated shapes can be contextual and harmonious.

This paper describes the characterisation of cine film, by identifying the relationship between the Status A density values of positive print film and the XYZ values of conventional colorimetry. Several approaches are tried including least-squares modeling, tetrahedral interpolation, and distance weighted interpolation. The distance weighted technique has been improved by the use of the Mahalanobis distance metric in order to perform the interpolation, and this is presented as an innovation.
