This study was motivated by a desire to help working-age individuals gain a better understanding of their daily nutritional intakes with a new self-reported dietary assessment method because an unhealthy eating behavior increases the risks of developing chronic diseases. In this study, we present the design and evaluation of NutriColoring, a food diary that leverages doodling on sketches to report and reflect on everyday diet in the working context. Through a 2-week field study involving 18 participants, the usefulness of NutriColoring in facilitating dietary assessment was tested by making comparisons with the typical bullet diary method. Our quantitative results showed that NutriColoring provided users with improved dietary assessment experience and intrinsic motivations, with significantly low task frustration and high enjoyment. Because of the freedom and playfulness in reporting intakes at work, the interview findings showed a high acceptance of employing NutriColoring at work. This article is concluded with a set of implications for the design and development of a Doodling toolkit to support healthy eating behaviors among office workers.
Timbre has been related to adjustment at the source as well as adjustments in resonance, including laryngeal height and hypopharynx area and volume. However, it is often presented in vocal pedagogy as solely related to resonance. Very little data is available on the laryngeal adjustments at both source and resonance involved in achieving various timbres across a variety of phonation types.

Production of dry encapsulated forms of anthocyanins from tulip petals with high antioxidant activity and their utilization in lipsticks.Anthocyanins (of the Greek anthos = flower and kianos = blue) are the most important pigments of the plants. These pigments are responsible of the shiny orange, pink, red, violet and blue colors in the flowers and fruits of some plants. The most interesting substances of the waste material are anthocyanins as natural water soluble antioxidants with a great health benefit besides the coloring properties. Tulip is a perennial bulbous plant which is popular worldwide and especially in the Holland due to the showy flowers of the great variety of colors and shades. It was found that for flowers of different colors biosynthesis of anthocyanins of the three anthocyanidin backbones may occur. Thus, pelargonidin (Pg), cyanidin (Cy) and delphinidin (Dp) derivatives, are responsible for tulip flowers color.
On a yearly basis 120 million kg of spent coffee ground (SCG) is disposed as waste. Two partners in the project have the intension to refine the valuable compounds from this coffee residue. One of these compounds is the group of melanoidins. It is proven that these natural polymers, with polyphenols incorporated, can be used as a colorant for wool. The polyphenols show antioxidant ability and high levels of ultraviolet radiation blocking which will give extra benefits when the SCG extract is applied as a colorant in smart packaging. In this project the extraction process is refined and industrial dyeing methods for wool, cotton and paper are evaluated. SCG colored samples are tested for color intensity and light and wash fastness. For the best coloring results commercial potential will be evaluated in a market study. Prospects in textile, paper and packaging industries are contacted to share their view about the possible applications of SCG extracts as colorants. The results are used in the business plan of the SCG refinery plant. With the SCG extract as a professional biobased colorant in the market, companies in textile, paper and packaging industry will have a wider choice in using environmental friendly products. At the end, this will lead to complete biodegradable products for consumers.
