4.5.2 Noble gas configurations under stress

It is remarkable how many molecules and ions of the typical elements can be represented by Lewis structures in which each atom has a noble gas shell structure. Nevertheless, many exceptions exist. According to the periodic trends summarised in Section 2, the highest fluorides of boron and phosphorus are BF3 and PF5. However, p

2.4 Obesity and brain reward systems

Very palatable foods, especially those high in fat and carbohydrate may be potent stimuli for neural pathways in the brain. Direct evidence for this idea has been found in recent studies of non-human animals. For example, it is known that many types of both natural (i.e. food, sex) and drug (e.g. cocaine or amphetamine, opiates, nicotine) rewards are able to stimulate activity within a brain pathway that innervates the ventral striatum at the base of the forebrain (Figure 8). The nerve cells

Fighting bushfires with explosives - clip 2
A shadowgraph representation of the blast, which involves positioning a simple cut-off filter in front of the camera to take advantage of the way light (in this case a very bright lamp shining into the test area) bends through air that is hot (around the flame) or suddenly changes in density (across the blast wave). Some light makes it into the camera while the light that has bent the most does not. The fact that light refracts like this is what makes us see a "mirage" of sunlight shimmering on

2.1.3 The comic scenes

There is no doubt though that the play keeps drawing our attention to its protagonist's weaknesses. The comic scenes in Act 1 serve to reinforce the connection between magic and appetite. In Act 1, Scene 4, Wagner tells us that Robin is so poor that ‘he would give his soul to the devil for a shoulder of mutton, though it were blood raw’ (ll. 9–11) and Robin adds: ‘Not so, good friend. By'r Lady, I had need have it well roasted, and good sauce to it, if I pay so dear’ (ll. 12–15).

9 The factory reform movement

Owen's participation in the movement for factory reform was clearly much influenced by views expressed in the essays. This showed his continuing concern, first evidenced in Manchester, about the impact of industrialisation on society, a theme to which he consistently returned. His personal record on the employment of children at New Lanark was certainly an example of good practice in the cotton industry, which in Owen's words was invariably ‘destructive of health, morals, and social comfort

3.6 Conclusion

I asked the question at the beginning of this section on Sundanese gamelan music: how is it possible for a group of musicians to play highly complex music, in a cohesive manner, without the use of notation and without having to memorise impossibly large amounts of music? My answer came in a number of stages.

  1. Rather than reading, or memorising vast amounts of music, the musicians memorise the simple frameworks of pieces (the Javanese term for this, bal

7.3.1 Library-based methods for demonstrating an interaction between proteins

As well as the biochemical approaches to studying protein–protein interactions, there is a variety of qualitative methods for screening ‘libraries’ of cloned genes or gene fragments whose protein products might interact with a protein of interest. Such an approach has the advantage that the genes that encode those proteins that bind are available immediately for expression, facilitating subsequent analysis of the protein.

4 Conclusion

Culture is just one perspective that can help us to understand more about a business. In this Unit we saw how the concept of culture developed from research into differences between cultures at a national level. Many cultural elements of a business are not obvious, but there have been some attempts in the academic literature to develop definitions and identify influencing factors. It is possible to see, or ‘feel’, that one business is different from another, and that this involves more th
