6.4.1 Materials selection Among the common thermoplastics available in the mid-1970s, polypropylene appeared as a front runner on grounds of toughness, density and cost Table 9). However, it is subject to creep (being uncrosslinked) and possesses a low tensile modulus of ca. 1500 MN m−2. Its merit index is 12.7 due to the low density of 0.9 Mg m−3, making it comparable to GRP. If it replaced GRP, here would be a
5.3 The rebound effect
Access to safe, clean and sustainable energy supplies is one of the greatest challenges facing humanity during the twenty-first century. This unit will survey the world’s present energy systems and their sustainability problems, together with some of the possible solutions to those problems and how these might emerge in practice.

What is ecology and why is it important to our understanding of the world around us? This unit looks at how we can study ecosystems to explore the effect that humans are having on the environment.
1.3 Activities Activity 2A sets the scene by focusing on the ‘big picture’ where you will be asked to choose between four alternative visions of the future. This activity radically shifts the scale of investigation from the personal to the global. However, as with all Author(s):

Stage 5: Comparison of Stages 2 and 4 The objective of the comparison stage is to relate the conceptual model to the problem situation as depicted in the rich picture. The idea is to highlight differences between the two so that potential improvements to the problem situation can be identified. Original Copyright © 2003, 2006 The Open University.

It then analyses the Tay Bridge disaster, which was caused by mechanical failure. Inevitably, human factors emerge as important in many major disasters. They may involve the failure by engineers, designers or managers to recognise faults in safety-critical products, or managers overriding the design team for other reasons – such as keeping to a dea 4.4.1 The map isn't the territory The expression ‘the map isn't the territory’ draws attention to the difference between complex reality and simplified models of it. Normally, the territory is relatively stable and different maps are produced for different purposes; the territory shapes the maps, not vice versa. However, when the ‘territory’ comprises people who know that they – or their work activities – are being mapped, we find ourselves in a reflexive loop: the people can see how they and thei Bulbs & Batteries in a Row 1.6 Teaching assistants in Europe Teaching assistants and other related learning support staff are also to be found in the schools for children of British armed forces posted overseas, in the schools of other European countries and, indeed, further afield in countries such as the USA, Canada and Australia. A survey conducted by the National Union of Teachers (NUT, 1998) highlighted some interesting support roles found in European schools, and it is worthwhile to consider these in the light of the developing role of teaching a 4.2 Actividad Here are three popular places to go in the Hispanic world.

Observe 6 E-government: other views 4.3 How effective are antidepressants in general? Despite the rapidly expanding use of antidepressants, to date there is very little evidence that they are effective for the treatment of bereavement or in mild to moderate types of depression. Recent meta-analyses (a technique for combining the results of a number of studies) reported by Joanna Moncrieff and Irving Kirsh, a British psychiatrist and psychologist respectively, show that selective serotonin re-uptake inhibitors (SSRIs), such as paroxetine (Seroxat) and fluoxetine (Prozac), have Nuevo vocabulario relacionado con el tono de un cuento Varios estudiantes de Bellas Artes 5.4 The politics of disability 2 Activities View the video below where you will see Shelly Woods in action during a tough fitness test. 1 Elite sport In this unit we will consider organisation and funding issues in elite sport. As with public sector sport, at the grass roots level a number of different organisations are involved, and it is difficult to identify clear leadership of this area. The National Lottery has had a major influence on the funding of our top sports people and the approach we take here is to look at how funding and organisation issues impact on one athlete, in this instance Shelly Woods (British wheelchair racing recor References 1 Preface Political theorists – classic writers such as Hobbes and Rousseau but contemporary ones too – have often assumed a neat fit between this government and that territory and its population, as if the fit between the two were somehow natural or timeless. Reality is always messier than that, of course. Countries, or nation-states, are in part constructed entities or communities – political units that are consciously demarcated and separated from others. As Guibernau comments, &
Everyday we are surrounded by circuits that use "in parallel"and "in series" circuitry. Complicated circuits designed by engineers are composed of many simpler parallel and series circuits. During this activity, students build a simple series circuit and discover the properties associated with series circuits.

Interpersonal communication in health and social care services is by its nature diverse. As a consequence, achieving good or effective communication – whether between service providers and service users, or among those working in a service – means taking account of diversity, rather than assuming that every interaction will be the same. This unit explores the ways in which difference and diversity impact on the nature of communication in health and social care services.
