1.6.1 Thiamin (or thiamine, also known as vitamin B1)

The deficiency disease beriberi has been known for thousands of years. The name literally means ‘I can't, I can't’ in Sinhalese (a major language in Sri Lanka), and reflects the crippling effect on its victims, who suffer from neurological symptoms, including pain, fatigue and paralysis, and cardiovascular disease. The disease was most common in southeast Asia, where white or ‘polished’ rice was a major part of the diet. The main source of thiamin is in the outer layers of the grain,

2.6 Centre and periphery

Here you have considered some of the ways in which the power and authority of the emperor were communicated to the inhabitants of the empire. The full dynamics of the relationship are difficult to reconstruct especially as the view gained is mainly from Rome looking out to the provinces rather than vice versa. It was important for the emperor to appear to be a competent ruler of the empire. It was one method used by his peers and successors to evaluate an emperor's reign. But it is often diff

1.6 Rings

David A. Rothery Teach Yourself Planets, Chapter 9, pp. 107-39, Hodder Education, 2000, 2003.

Copyright © David Rothery

Planetary rings consist of hordes of particles sharing orbits in their planet's equatorial plane, and occur around each of the four giant planets. Their width varies from planet to planet, but in general their thickness is no more than a few tens of kilometres. They generally lie close to their planet, inside what is known as the Roche li

Introduction

This unit looks at equity finance – the range of equity instruments and markets available to a company. First, we look at private equity and the role of venture capital companies that provide such finance. We look at the mechanics of an initial public offering (IPO) and at recent cases of companies ‘listing’ on a stock exchange for the first time. We go on to explore certain important strategic issues for a business when considering equity finance:

1.6 Interlude

Now that we have covered the features found in igneous, sedimentary and metamorphic rocks, and seen how these features can be explained by the processes that formed the rocks, here is a useful point at which to have a break before continuing with the next section. Before returning, you might like to see for yourself what types of rock you can find in your area. Can you identify their texture, or spot any fossils? Surfaces that haven't been obscured by grime or lichens are by far the best, as

2.4 Drawing circles

Drawing circles freehand often produces very uncircle-like shapes! If you need a reasonable circle, you could draw round a circular object, but if you need to draw an accurate circle with a particular radius, you will need a pair of compasses and a ruler. Using the ruler, set the distance between the point of the compasses and the tip of the pencil at the desired radius; place the point on the paper at the position where you want the centre of the circle to be and carefully rotate the compass

5 Hyperbolic functions

In Section 4 we introduce the hyperbolic functions sinh, cosh and tanh, which are constructed from exponential functions. These hyperbolic functions share some of the properties of the trigonometric functions but, as you will see, their graphs are very different.

1.3.1 Introduction

Holding up the East Asian success story as the way forward has, as I indicated above, little appeal for the antisweatshop movement. For its members, a different image comes to mind of thousands of workers eking out a living from the numerous sweatshops which dot that part of the world: one that involves the perpetuation of poverty wage levels, the use and abuse of poor communities, and the constant taking advantage of what is ready to hand, followed by withdrawal and abandonment.

Of course, doing anything about this needs scientific evidence and understanding, but it also requires social, economic and technological changes, which can only be achieved through political will. If you want to explore some of the broader context, a good place to start would be the New Internationalist issue 357, ‘The Big Switch: Climate Change Solutions’ at New Internationalist.

7 Conclusion

One might think of the different interpretations of internationally recognised notions of rights and justice as running along a spectrum, from which we shall now identify four different positions.

  • The first interpretation would argue that, overall, the extension of rights to the international sphere has been benign and effective. It has led and will lead to further successful claims for justice.

Cyborgs and cybernetics
What are cyborgs? Would a cyborg future deliver positive human advances or a Hollywood-style nightmare in which human beings have become a sub-species? Could we one day download our minds? This album gives an insight into the development of cybernetics and how it is used to fuse technology and humanity. The interfaces that communicate between man and machine are developing rapidly and to Prof. Kevin Warwick at Reading University, cyborgs are a technological evolutionary step forward from humans.

Structural Integrity: designing against failure
The Kinzua rail viaduct, in Pennsylvania, collapsed when it was hit by a tornado in 2003. First built in 1882 and redesigned 1900, it was at one time the highest bridge in the world. The two video tracks in this album tell the story of the Kinzua catastrophe. The subsequent forensic investigation has cast new light on the failure of Tay rail bridge in Scotland 125 years earlier; with 75 people killed, the worst ever disaster to befall a trestle bridge.
