This course is an introduction to chemical oceanography. It describes reservoir models and residence time, major ion composition of seawater, inputs to and outputs from the ocean via rivers, the atmosphere, and the sea floor. Biogeochemical cycling within the oceanic water column and sediments, emphasizing the roles played by the formation, transport, and alteration of oceanic particles and the effects that these processes have on seawater composition. Cycles of carbon, nitrogen, phosphorus, oxy

1.5.1 Interdependence

Although Katrina's mother depends on Katrina for some of her own needs and the needs of the younger children, she also cares for Katrina in that she is legally and financially responsible for her. She is also able to give love, advice and support. So it is a two-way relationship. Nevertheless, young carers challenge prevailing ideas about what children or young people do in families. There is apparently a ‘role reversal’ – as Katrina put it so neatly, her mum expected her to be an adult

1.7 Every picture tells a story: summing up

In summary, this section has looked at time-series graphs, conversion graphs and mathematical graphs. Like all representations, graphs draw from a range of common conventions and styles to convey meaning. From a mathematical point of view, graphs give a visual impression of the relationship between two (or sometimes more) variables; but bear in mind that this impression is largely under the control of whoever draws the graph. When you are drawing graphs for yourself or others, you need to cho

Differences in the neural basis of Chinese and English reading
Introduction: Previous functional imaging studies comparing Chinese and English reading have reported that a left middle frontal region is more activated by Chinese reading and the left superior temporal cortex is more activated by English reading (Tan et al. 2001; 2003). We investigated this finding and its interpretation by conducting a functional magnetic resonance imaging (fMRI) study of reading in China and England using monolingual adolescents who spoke Mandarin or English respectively.

3 Biographical perspective: using pathways

You will shortly be hearing excerpts from interviews with four men, who were contacted through the Swansea Cyrenians. They are all from very different backgrounds, and talk about their own experiences of homelessness.

The clips are only brief insights into life without a home, but they do demonstrate the importance of a biographical perspective in understanding the unique and diverse needs of individual homeless people.

Looking at situations from a biological perspective is

18.413 Error-Correcting Codes Laboratory (MIT)
This course introduces students to iterative decoding algorithms and the codes to which they are applied, including Turbo Codes, Low-Density Parity-Check Codes, and Serially-Concatenated Codes. The course will begin with an introduction to the fundamental problems of Coding Theory and their mathematical formulations. This will be followed by a study of Belief Propagation--the probabilistic heuristic which underlies iterative decoding algorithms. Belief Propagation will then be applied to the dec

1.2.2 Summary

  • The results of successive editions of the Eurobarometer show that in most EU countries only a very small percentage of people, around 5 per cent, declare having an exclusive European identity, while up to 50 per cent do not have any sense of European identity.

  • European political identity is weak and there is a great variation across states.

2.4 Analysis of nucleic acids by electrophoresis and hybridisation

Nucleic acids can be separated according to size by gel electrophoresis, most commonly performed using a horizontal gel (Figure 7a). This is in contrast to the vertical gel electrophoresis set-up, which is generally used for analysis of proteins.

The size of DNA molecules is usually expressed in terms of the number of
