6.3 Directing the growth cone The growth of the growth cone has been likened to the progress of a climber. The climber can only go where there are satisfactory hand and foot-holds and where progress is not blocked by physical obstacles (e.g. overhangs or ice). Furthermore, the climber is looking ahead for the best routes, from the current position to the top. Likewise the filopodia on the growth cones are extending outwards, adhering to the best holds and avoiding physical obstacles (e.g. bone or cartilage). This contact-

6.3.3 Photomultiplier tubes and detection circuitry The visible photons are collected by an array of photomultiplier tubes behind the crystal. These convert each visible photon to an electron and then multiply the number of electrons sufficiently to give a voltage pulse. Because the number of visible photons is proportional to the energy of the incoming gamma ray, the height of the pulse depends on this energy. This gives a method of counting the numbers of gamma photons at different energies that reach the crystal. A resistive network c
1.8.1 Making and using field sketches How do we start to make sense of a rock exposure? Drawing a sketch is one of the best ways to start, as it forces you to notice many aspects of the exposure. It also helps you to build up a picture of which aspects are significant and which are incidental or even irrelevant to a geological study. The aim of a field sketch is that it provides a record of your observations (along with notes taken at the same time, and also perhaps a photograph to record details). A sketch is complementary to a

2.1 Structure and function of the outer and middle ear Figure 1 is a diagram of the human ear. The outer ear consists of the visible part of the ear or pinna, the external auditory canal (meatus), and the tympanic membrane (tympanum) or eardrum. The human pinna is formed primarily of cartilage and is attached to the head by muscles and ligaments. The deep central portion of the

3.4 Second messengers In the previous section, we have discussed the principles of second messengers (Section 1.5) and, in particular, those produced by PLC (IP3 and DAG) and PI3 kinase (PI(3,4)P2 and PI(3,4,5)P3). We shall now consider the roles and mechanisms of action of the other chief mediators, which are Ca2+ ions, cAMP and cGMP

9 Metre As we have seen, scansion is the act of mapping out stress patterns in order to ascertain the metre (rhythm). In the accentual-syllabic system, the dominant tradition in English, both accents (stresses) and syllables are measured and counted. In accentual metre, the stresses are counted and the syllables can vary. In syllabic metre, the syllables are counted, while the stresses can vary. Here is pentameter, the line of fi 1.3 When is the right time to take notes? Any time that suits you! Increasingly we live in an age where there is more information than we can possibly hope to deal with. One of the most important skills you (or any of us) can develop is how to cope with all this information. Note taking is just one skill that will help you do this. It is important to get into the habit of making notes, and the best way to do this is to find a method that suits you (and the medium you are working in). Oxford Women in Politics with Dr Anne-Marie Slaughter 7.7 Planning for quality Having considered estimating for time and for costs, the third dimension of projects – quality needs to be considered. The need to achieve a particular level of quality may mean that more time must be spent completing certain tasks or that more resources must be made available for a particular purpose. Once the time and cost estimates have been made, review them to ensure that this estimate will allow an outcome of the right quality. Many organisations have corporate quality assurance Introduction Participating in the democratic processes is seen as being a fundamental aspect of citizenship. All pupils need a broad knowledge and understanding of the rights, responsibilities and duties of citizens, as well as an understanding of forms of government. Notions of citizenship have been forged alongside the expansion of the right to vote and the development of our ideas about democracy. In this unit we explore different interpretations of democracy and strategies for involving pupils in con 1.7 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 A Guide to Plot Development in Plays 9.1 The psychological arena The examples in the previous section followed the traditional medical approach, namely that there is a disease, it can be diagnosed (identified), and the cause of the disease, be it viruses, bacteria, pathogens, genes or poisons, can be sought. This section moves away from the medical arena and into the psychological arena, where the symptoms are behavioural. In this case, the symptoms are socially unacceptable behaviour and to the list of causes just mentioned is added family circumstances a PES Celebration
