The crystalline swelling of smectites in electrolyte solutions can be controlled by varying the salt concentration of the solutions (Norrish and Quirk 1954, Norrish 1954a, Slade et al 1991). Such osmotic control offers a convenient means of studying the energetics of crystalline swelling. Several X-ray diffraction (XRD) techniques have been developed for measuring the basal spacing of smectites...

Attention is what allows one stream of information from the internal or external environment to be selected over others and therefore pervades almost any thought or action we take in our daily lives. It is little wonder then that defi cient attention, a common feature of many disorders of the brain (see Manohar, Bonnelle and Hunter (chapter 34), this volume; Vallar and Bolognini (chapter 33), t...

The literature on judicial selection systems has given considerable attention to the role that politicians and their parties – through their legislative roles – have played in the adoption and operation of these judicial selection systems. Less attention, however, has been given to both the effect that interest groups, broadly defined, have in the creation and implementation of judicial selecti...

Posner hypothesised that the legalisation of assisted suicide may substitute for unassisted (unregulated) suicide. We test predictions arising from this hypothesis using data US states have legalised Event study regression estimates provide strong evidence is associated with an increase in total suicides, especially females and older people. There some laws are also a smaller suicide, though st...

A 32-year-old man with blurred vision in the right eye and headache presented with anterior uveitis, an intraocular pressure (IOP) of 60 mmHg, an open angle, no visual field defects, and normal optic nerve. He had a history of five previous similar attacks. In each of the previous instances, his anterior uveitis and high IOP were controlled with antiglaucoma medications and topical steroids. Ho...
