Science in Focus: Energy: Workshop 7. Heat, Work, and Efficiency
A machine's energy output cannot be greater than its input. In this session, look at the energy that goes into useful work, examine how some always ends up as heat, and see why systems are never 100% efficient.,This segment explores the question "How can we get work from heat?" by visiting classrooms as well as interviewing students and scientists.

2.3 Summary

In this unit we have used the Blackwater to identify the theme of environmental response. Responses involve the interaction of human and natural processes. For example, the rise in sea level experienced in the estuary is partly natural readjustment after the Ice Age and partly a response to greenhouse gas emissions caused by human activity. This rise has brought about two forms of response: human responses to change in the environment and responses made by the environment.

1.2.2 Change and response in the ‘meadows of the sea’

Midway along the northern shore of the Blackwater estuary lie the Old Hall Marshes on a peninsula three and a half miles long and lying between tidal creeks and mudflats (see Figures 3 and 15a). It is a wild, flat, remote area of mixed habitats of reedbed, open water, saltmarsh and improved and unimproved grassland. Ecologically, it constitutes coastal grazing marsh (Author(s): No creator set

1.2.1 Managing risk in conditions of uncertainty

Earlier we considered what is meant by ‘environmental responses’. There are two aspects to this concept. One is the response made by the environment to processes of change, whether brought about by natural or human causes or a combination of both. The other is the response to environmental changes made by humans or non-humans. In this section we shall consider both of these aspects of response by focusing on an issue of particular significance in the Blackwater: how the

1.1.2 A balancing act: conservation and sustainable development

All around this coast are examples of efortsf to protect or enhance the environment. There are nature reserves, country parks and protected habitats, and the whole coastal fringe is designated as an area of scientific interest requiring special protection. There is also evidence of the need to manage the environment to ensure, so far as possible, compatibility between competing interests. Built development is prevented along the shoreline and restricted to existing settlements; caravan parks

Since 1775 America's smallest armed service has been suspicious of outsiders and deeply loyal to its traditions. Undying faith in its exceptionalism made the Marines one of the sharpest, swiftest tools of American military power, but developing this brand did not come without costs. Aaron B.

Professor David Shambaugh: China goes global, but only partially
In this video world-renowned China scholar Professor David Shambaugh examines China's place in a global world. Contrary to conventional wisdom, Shambaugh argues that China is not a superpower but rather a 'partial power'. Based on a five-year study which has culminated in his latest book, China goes global: the partial power, Shambaugh argues that rather than 'rising', China is 'spread' across the globe -- with a growing international footprint that is broad but not deep. David Shambaugh is a

'Natural capital'
CEOs of businesses in emerging economies are taking the lead over their European counterparts in understanding the importance of sustaining their 'natural capital' - the genes, species and ecosystems that together make up life of Earth. "Historically the emerging economies, particularly China, have not addressed the short-term effect they are having, with its long-term impact, on natural capital, but we've seen a growing change in that," explains Dr Rands.
