Surface water
Water is arguably the most important physical resource as it is the one that is essential to human survival. Understanding the global water cycle and how we use water is essential to planning a sustainable source of water for the future. In the UK there area areas where water supplies are limited, as shown by recent droughts. Globally, there are many areas that do not have enought water to support the currently population adequately. Decisions will have to be made on the best way to use water in

1.1 From drop-towers to Oblivion - some applications of linear motion

We have all experienced that momentary feeling of lightness when an elevator begins its downward motion. It is almost as if our weight had suddenly been reduced or, conceivably, that the pull of the Earth's gravity had decreased for a moment. But imagine what it would be like if the lift cable had suddenly snapped and the lift, with you in it, had plummeted downward. Apart from stark terror, what else do you think you would experience during your fall? What would the physical experience

4.2 Experimental domestication of foxes

In 1959, the Russian geneticist Dmitri K. Belyaev (1917–1985) launched a long-term experiment to tame captive-bred red foxes by selecting for a single behavioural trait: lack of fear and aggression towards humans. Over 40 years, more than 45 000 foxes were bred in captivity at a remote farm near Novosibirsk, Siberia. Various behavioural, physiological and morphological characters were studied in each fox. Selection for tameness was strict: each animal was assessed once a month for seven mon

4.2.1 ATM physical layer

The ATM physical layer is divided into two sub-layers: the transmission convergence sub-layer and the physical medium sub-layer.

Functions of the transmission convergence sub-layer include generating and receiving cells, and generating and verifying the cyclic redundancy check in the header error control field. For correct interpretation of ATM cells it is important to identify the beginning of a cell. In theory, if ATM cells are transmitted as a continuous stream of bits,

3.1 Introduction

How evolution proceeds is obviously of central importance when studying mammals. Of fundamental importance to the way evolution works is the notion of natural selection, and in S182_3 Studying mammals: chisellers I'll be talking about what most researchers regard as this 'single most important idea in biology'. But before that, I want to describe some of the adaptations evident in insect eaters.

From your reading of LoM you'll appreciate that natural selection promotes the evolut

1.3.6 Stage 4: Extracting the information

You probably feel that you now have all the information the piece of writing contains or that you need, but now we need to categorise the information it contains and to look for connections with our own social scientific concerns. This is the difficult bit, and we don't expect you to be expert at it yet.
