Combined Chemical and Biosynthetic Route to Access a New Apoptolidin Congener

Article Processing Charges: A New Route to Open Access?

Article Processing Charges (APCs) have recently been studied as a means towards a sustainable Open Access (OA) environment for scholarly communications. However, APCs at any level represent a substantial economic barrier to the authors, institutions, funding agencies and governments that many of its advocates most wish to serve through OA initiatives.

The biosynthetic route from ornithine to proline.

It is shown by tracer experiments with DL-[2-3H,5-14C]- and DL-[(RS)-5-3H,5-14C]rnithine, that the metabolic conversion of ornithine into proline, in three plant species (Nicotiana tabacum, Datura stramonium, and Lupinus angustifolius), takes place with maintenance of the delta-hydrogen atoms but with loss of the alpha-hydrogen atom. This indicates a route via alpha-keto-delta-aminovaleric acid...

Democratizing Access to Calculus: New Route to Old Roots

1 The Role of History in Mathematics Education The history of mathematics in general and calculus in particular has been thoroughly studied over the past few decades. There are, for example, 14 books and papers cited in Kaput's chapter. More recently, a few researchers in mathematics education have taken the point of view that the historical development of a mathematical topic, in particular th...
