3.3.3 Screen readers and speech synthesisers

A screen reader monitors the information sent from the computer to the screen. It makes decisions about which part of the screen to read and in what order, then passes this information to either a speech synthesiser or a Braille display. All screen readers support speech synthesisers and most support Braille displays.

The first speech synthesisers were hardware, usually a small box that sat on the desktop and had its own speaker, or a card that fitted inside the computer and used extern

Introduction

Even the simplest organisms can detect and respond to events in their ever-changing environment. Similarly, within a multicellular organism, cells are surrounded by an extracellular environment from which signals are received and responded to. Extracellular events are decoded and transmitted to relevant parts of individual cells by way of a series of activation/deactivation steps involving many intracellular molecules. This relay of information along molecular pathways is called signal tra

6.3.1 Latent heat

The origins of Black's interest in the phenomenon of melting have been the subject of some debate. John Robison remarked, in his edition of Black's lectures, that Black had been struck by the simple fact that snow does not melt instantly on a sunny winter's day nor does a sharp night-time frost cause ponds to form thick layers of ice immediately (Robison, 1803, vol. 1, pp. xxxvi-xxxvii). It is now generally agreed, however, that Black's interest in heat arose from his study of the temperature

Making Sovereign Finance and Human Rights Work
Discussion of 'Making Sovereign Finance and Human Rights Work,' a recently-published collection that introduces novel legal theories and analyses the links between sovereign debt and human rights from a variety of perspectives. Poor public resource management and the global financial crisis curbing fundamental fiscal space, millions thrown into poverty, and authoritarian regimes running successful criminal campaigns with the help of financial assistance are all phenomena that raise fundamental q

1.4 Grades and clades

If species are grouped together because they show a similar extent of accumulated anagenetic change with respect to their ancestors, then the taxa so formed constitute grades. In Figure 1, morphological change is represented along the horizontal axis. The three columns show grades of anagenetic modification, with pa

5.3 The Marseillaise

During the Revolutionary Wars, as Robespierre insisted, ‘republican enthusiasm must be exalted by all means possible’. The Jacobins encouraged a revolutionary solidarity and patriotism, expressed in the slogan ‘Liberty, Equality, Fraternity’. The Marseillaise began as the ‘battle-hymn of the army of the Rhine’, composed by Rouget de Lisle in April 1792 immediately after France declared war on Francis of Austria. It acquired its name when a battalion of volunteers from Marse

4.3 Type-II superconductors

For decades it was assumed that all superconductors, elements and alloys, behaved in similar ways, and that any differences could be attributed to impurities or defects in the materials. However, in 1957, Abrikosov predicted the existence of a different sort of superconductor, and Figure 23 shows direct evidence for the existence of what are now known as type-II superconductors. A comparison of Figures 23 and 22 indicates that the effect of an applied field on a type-II superconductor is rath

3.5 Electrophysiological studies of language processing

Brain imaging and aphasic studies helped us localise the subparts of language processing within the brain. However, they have shed little light on how processing unfolds in real time. This is because contemporary brain imaging is quite poor at showing changes in activity through time in fine detail, so it is hard to pick up something that may be happening slightly before something else.

3.2 Removal of iron

Before leaving enterobactin to look at iron transport and storage in humans, it is worth asking the question: how does E. coli remove the iron from such a stable complex as the iron(III)–enterobactin once it has been absorbed?

The answer to this question can be found if we look back to reaction 38. The rigid, three-dimensional structure of the triserine ring of enterobactin is the main reason why enterobactin is such an effective ligand. If the structure of the ring is destroye

1.3.5 Corporate connections

As I mentioned in Section 2, what was happening in the factories of overseas contractors was said to have appeared remote to most, if not all, the chief executive officers of the clothing multinationals in the 1980s. Overseas contractors were selected on the basis of market price, quality and reliability, not on whether forced or child labour happened to be employed to stitch the product together. However, all that changed in the early 1990s when the geographical ties between the big retailer

3.2 General search engines

An immediate temptation is to head straight for a search engine such as Google and enter your family name, but a moment's thought should warn you that the results will be disappointing. This is particularly so if your name is common or, like White or Snow, is also an English word. Even a relatively uncommon family name such as Rosewell turns out to be a place name in both Scotland and the USA and a misspelling of a UFO.

Guns, Drugs, and Booze: The Bipartisan Support for Prohibition

It’s been noticed more than a few times that there aren’t many substantive differences between the Republicans and Democrats. While this is true in many ways for the parties themselves, the Left and Right certainly differ on a range of issues from welfare to abortion to gay rights.

What they have in common — at least the mainstream varieties — is a desire to use the state to shape society in whatever way they see fit. As Andrew Napolitano put it, “We have m
