Advancements in Underwater Vehicles: Responding to Current Environmental Issues
Even if humans could breathe under water like fish, we might not want to become permanently aquatic. “Believe it or not,” says James Morash , “the deep ocean is kind of boring,” covered as it is by so much sandy sea floor. And yet there’s much to be learned about this terrain, which was a mystery to humans

1 A revolution in schools
There is an ongoing ‘revolution’ in the running of state schools and this is making the position of the school business manager both significant and necessary. Government thinking, together with profound changes in society generally, will affect every institution both in terms of pedagogy and the physical environment, particularly technology and levels of security employed. This unit will look at how you – an existing or aspiring business manager – can work effectively to support school

Global warming
This unit provides an introduction to global warming. We will be considering the history of global warming by looking at the pattern of ice ages and analyisis of recorded temperatures. We will aim to gather meaningful information from this data. We will briefly assess the impact and influence of humans on global warming and, finally, we will examine climate models and how to predict future changes.

5.2 Cancellation and reinforcement

I have shown that a phase difference between two points in space arises as a natural consequence of the finite time it takes a pressure wave to travel between two points in space. This is not the only way in which a phase difference can arise. A phase difference can arise between two sine waves if one is delayed relative to the other. Also, almost any form of electronic sound-processing equipment affects the phase of the signal it is processing, so that what comes out is not in phase with wha

Southern Women Trailblazers
The twentieth century was a time of great social change in America. One example of remarkable change was in the role of women in American society. Across the country, and particularly in the South, traditional ideas defined acceptable roles and behavior for women. However, some women challenged these norms by pursuing higher education or professional careers at a time when the accepted role for a woman was wife and mother. These trailblazers contested accepted views about women’s abilities

Change in the Mountains
The Appalachian Mountains of western North Carolina rise abruptly from the Piedmont, the state's central plateau, and include the ranges of the Balsam, Black, Blue Ridge, Great Smoky, and Nantahala Mountains. The region is home to several of the highest peaks east of the Mississippi River. The rugged geography of these mountains delayed the arrival of European settlers to the area, slowed the pace of development, and for many years preserved a distinct regional culture. While development and c

1.3.1 Evergreen plants
In this unit, we study one aspect of the fluctuating nature of an organism's environment. We consider how organisms living in a temperate climate, such as that in Britain, are adapted to cope with winter. You will see that there is much diversity of adaptations among organisms, with different species coping with the demands of a fluctuating environment in quite different ways. As cyclic variations are a widespread feature of environments, the range of adaptations to them is an important source o
