Combating air pollution
What’s in the air you breathe and how do you know it’s safe? Pollution control is vital since nobody has a choice when it comes to inhaling the air around them. This album introduces the scientific processes behind air monitoring and air quality management. The five video tracks explore the nature of pollution arising from different forms of transport, and look at how data is interpreted and how pollutants can be minimised. To complete the album, Senior Lecturer Rod Barratt explains the cho

6.3 Summary of Sections 4 to 6

Hair cells do not have axons and therefore do not generate action potentials.

The nerve that communicates with or innervates the hair cells along the basilar membrane is known as the vestibulocochlear nerve or VIIIth cranial nerve. The cochlear portion of the nerve contains afferent fibres that carry information in the form of action potentials from the organ of Corti to the brain, and efferent fibres that bring information from the cerebral cortex to the periphery.

Introduction

Nature Matters considers environmental responsibility and what may matter from a caring perspective and an accountability perspective. A reading by Andrew Light reflects on four key debates in environmental ethics regarding the way in which nature is valued, and prompts the question on how such debates might inform environmental responsibility.

Section 2 examines the formal processes involved in developing accountability in the context of sustainable development. The persuasiveness of t

Environmental engineering
The Department of Chemical and Environmental Engineering has concerns about the lack of knowledge amongst school pupils, and their teachers, of the type of work undertaken by an Environmental Engineer. The interactive presentation was developed as part of an awareness raising exercise for aspects of Environmental Engineering. Targeted at KS3 pupils particularly in Year 9 (Y9) the themes of air/ soil/water pollution were chosen because of their links to the KS3 National Curriculum for Scie

3.3.2 Citizenship beyond (species) borders

Political philosophers are struggling to fit together conventional ideas of citizenship and issues of global environmental change. Most have simply ignored these momentous challenges: they have failed to fully comprehend the implications of our new understanding of humans' revised place in the world.

However, our advancing awareness of global environmental changes draws us into a very different sense of shared fate from that of the nation state, or even the global citizen. As Chapter 5

1.9.1 Moving around the rock cycle

One way of illustrating the possible ways of moving material around the rock cycle is to draw a diagram that places the processes into their geological contexts. Since the rock cycle involves processes occurring on the Earth's surface and also within its interior, we use a cross-section through the Earth's crust and uppermost mantle to do this, as shown in Author(s): The Open University

6.3 Where are they now?

At the beginning of this course we asked whether active galaxies really are in a class of their own or whether most galaxies go through an active stage at some point in their lives. We can shed some light on this by looking for evidence that active galaxies evolve.

The first question is where AGNs came from. No-one knows how supermassive black holes formed and the question is intimately tied up with the origins of galaxies which is itself a vigorously debated topic. But it is likely tha

1.5 Obesity

At the time of writing (2004) 20% of the adult population of the UK is classified as obese. The number of obese children has doubled since 1982, 10% of six year olds and 17% of fifteen year olds are now classified as obese. As shown in Table 4, obesity is recognized when the BMI exceeds 30 and occurs quite simply when energ

Economic Dilemmas and Solutions
Steven Page is a 12th–grade economics teacher at Vivian Gaither Senior High School in Tampa, Florida. In this lesson, students review and interpret the government’s role in the economy. Working in groups, students examine economic dilemmas, including the implications of human cloning, year–round schooling, and drug legalization. Students then reach consensus on a "proper" economic decision and present their findings in the form of a skit, followed by a group discussion.

5.2 Cryogenic liquids and ionising radiation safety

5.2.1 Cryogenic liquids

There are a number of hazards associated with cryogenic liquids, the main one being that when accidentally released the liquid expands hugely to form a gas (600 times in the case of nitrogen). The formation of such a large volume of gas can lead to asphyxiation in confined areas.

The other main hazard is cold burns (frostbite).
