Conway and Smith’s book is a wonderful introduction to the normed division algebras: the real numbers (R), the complex numbers (C), the quaternions (H) and the octonions (O). The first two are well-known to every mathematician. In constrast, the quaternions and especially the octonions are sadly neglected, so the authors rightly concentrate on these. They develop these number systems from scrat...

There exist few virtual learning environments (VLEs) which allow teachers to make learning design decisions explicit and reusable in other environments. Sadly, those few VLEs that do so, are not available to most teachers, due to institutional decisions and other contextual constraints. This panorama is even grimmer if a teacher wants to use not only the tools offered by the institutional VLE, ...

The management of patients with suspected viral encephalitis has been revolutionised in recent years with improved imaging and viral diagnostics, better antiviral and immunomodulatory therapies, and enhanced neurointensive care. Despite this, disasters in patient management are sadly not uncommon. While some patients are attacked with all known antimicrobials with little thought to investigatio...

Many surveys have been written on the Novikov Conjecture. The goal here is to give an old-fashioned point of view, and emphasize connections with characteristic classes and the topology of manifolds. For more on the topology of manifolds and the Novikov Conjecture see [58], [47], [17]. This article ignores completely connections with C§-algebras (see the articles of Mishchenko, Kasparov, and Ro...

By (morphologically) similar wordforms we understand wordforms (strings) that have the same base meaning (roughly, the same root), such as sadly and sadden. The task of deciding whether two given strings are similar (in this sense) has numerous applications in text processing, e.g., in information retrieval, for which usually stemming is employed as an intermediate step. Makagonov has suggested...

This paper shows how lazy functional programs can be made mobile by compiling them for the Java Virtual Machine. The Haskell compiler it describes is based on the h,Gi-machine, which is designed for implementing lazy functional languages on parallel processors. Although this is not the obvious thing to do, it leads to a particularly elegant set of translation rules. Sadly though, the speed of t...

Ontologies are becoming increasingly important in a variety of different fields, such as intelligent searching on the web, knowledge sharing and reuse, knowledge management, etc. Therefore, we expect that the need for tools to support the construction of ontologies will increase significantly in the coming years. In this paper we investigate several of these tools. We evaluate the tools using t...

A comprehensive account of the status of rattans found in the north-east region of India is presented here. Out of the 600 species found worldwide, a total of 20 species of rattan are found in North-East India. Rattan is inseparably attached with the tradition and culture of tribal people of the North-Eastern region. Since antiquity, people of this region have used to make many articles of dail...
