This article highlights several applications of mathematics to the design of musical instruments. In particular, we consider the physical properties of a Norwegian folk instrument called the willow flute. The willow flute relies on harmonics, rather than finger holes, to produce a scale which is related to a major scale. The pitches correspond to fundamental solutions of the one-dimensional wav...

In most cases the pharmacological activity of plant extracts is not assigned to single components and often not all active ingredients are known. Approaches other than those considering single compounds only to analyze plant material have proven helpful for a better characterization of extracts in their entirety. In this study extracts of willow bark are analyzed by high-performance thin-layer ...

The application of aspirin-like drugs in modern medicine is very broad, encompassing the treatment of inflammation, pain and a variety of cardiovascular conditions. Although anecdotal accounts of willow bark extract as an anti-inflammatory drug have occurred since written records began (for example by Hippocrates), the first convincing demonstration of a potent anti-pyretic effect of willow bar...

This paper describes the use of adaptation patterns in the task of formulating standards for adaptive educational hypermedia (AEH) systems that is currently under investigation by the EU ADAPT project. Within this project, design dimensions for high granularity patterns have been established. In this paper we focus on detailing lower granularity adaptive patterns based upon learning styles. Sev...

This paper aims at providing a preliminary study of the effects of different doses of tannery waste containing high amounts of organic substances, mineral elements and heavy metals on growth dynamics and metal accumulation in willow plants. Scions of Salix alba L., clone S61-02, were grown in the open near Pisa (Italy), in pots filled with a natural soil. Willows were pruned for a unique shoot ...

While working in his garden in the spring of 1763, English clergyman Edward Stone was positive he had found a cure for malaria. Tasting the bark of a willow (Salix alba), Stone noticed a bitter flavor similar to that of fever tree (Cinchona spp.), the Peruvian plant used to make quinine. He reported his discovery to the Royal Society in London, recommending that willow be tested as an inexpensi...
