The employment of au pairs to provide childcare, cleaning and other domestic services has been steadily increasing in the UK. This article provides an analysis of representations of au pairs in the British press and on the websites of agencies placing au pairs. This analysis seeks to understand how such imaginings of au pairs affect their life in Britain and how au pairs themselves respond to s...

The linear Doppler shift is familiar as the rise and fall in pitch of a siren as it passes by. Less well known is the rotational Doppler shift, proportional to the rotation rate between source and receiver, multiplied by the angular momentum carried by the beam. In extreme cases the Doppler shift can be larger than the rest-frame frequency and for a red shift, the observed frequency then become...

Three new Brazilian species of the Brevantherum clade of Solanum (Solanaceae) are described, all closely related to the poorly known Solanum inornatum Witasek. Solanum bradei Giacomin & Stehmann, sp. nov., and Solanum kriegeri Giacomin & Stehmann, sp. nov., differ from S. inornatum in having very small deltate calyx lobes that are not accrescent in fruit. Solanum bradei is a shrub up to 1.8 m w...

A successful endodontic treatment depends on appropriate instrumentation, irrigation, decontamination and obturation. Chemomechanical instrumentation removes majority of the infecting bacteria, but this is not achieved completely because of complex root canal anatomy and limitation in accessing the root canal system (Manzur et al., 2007). Persistent endodontic infection might be attributed to t...

This book first arose out of a passage in Borges, out of the laughter that shattered, as I read the passage, all the familiar landmarks of my thought—our thought, the thought that bears the stamp of our age and our geography—breaking up all the ordered surfaces and all the planes with which we are accustomed to tame the wild profusion of existing things, and continuing long afterwards to distur...

It is a great pleasure for me to report on the recent spectacular developments concerning the Poincaré Conjecture. Grigory Perelman has solved the Poincaré Conjecture. He has shown that, as Poincaré conjectured, any closed, simply connected 3-manifold is homeomorphic to the 3-sphere. The paper in which Poincaré posed this problem in 1904 ([14]) marked, in my view, the founding of topology as an...

The prospect of using genes as therapeutic agents presents myriad opportunities. No physician could fail to appreciate the power of this approach: why not abandon the shackles of the limited pharmacological and device repertoire and focus instead on reengineering the culprit tissue by somatic gene transfer? The explosion of genomic information leaves us with an embarrassment of riches in terms ...

Perilymph fistulae are difficult to diagnose because they present with a wide variety of signs and symptoms, they are associated with many etiologies, and they often mimic other conditions. In this article, we describe a case of perilymph fistula that featured one of its more rare causes: acoustic trauma--specifically, damage from a loud blast from the siren of a fire engine. We also review the...

This study was carried out during 2002-2005 in the east Mediterranean region of Turkey (in Kahramanmaras province), at the experimental field of Agricultural Faculty of Kahramanmaras Sutcu Imam University. Four naturally coloured cotton lines (light brown, dark brown, cream and green) (G. hirsutum L.) brought from Azerbaijan National Academy, Genetic Resources Institute and white linted cotton ...
