An introduction to social work in Wales
Respecting the individuality of each person is a central value of social work but, as the term suggests, social work is not only about individual perspectives: it also takes place in a social context. Society, demography, geography, national legislation, national policy, and language all play an important part, both in the lives of service users and carers and in the practice of social work practitioners. This free course, An introduction to social work in Wales, will introduce you to the import

3.22 Division rules

Lastly consider division. Dividing 8 by 2 means ‘How many times does 2 go into 8?’ or ‘What must you multiply 2 by to get 8?’. The answer is 4.

So to find 8 ÷ 2, you need to ask ‘What do I have to multiply 2 by to get 8?’. The answer is 4, since 2 × 4 = 8.

So 8 ÷ 2 = 4.

Similarly, to find 8 ÷ 2 you need to ask ‘what do I have to mul

Hydrophone spatial averaging corrections from 1 to 100 MHz
The purpose of this work was to develop and experimentally verify a set of robust and readily applicable spatial averaging models to account for ultrasonic hydrophone probe's finite aperture in acoustic field measurements in the frequency range 1 - 100 MHz. Electronically and mechanically focused acoustic sources of different geometries were considered. The geometrics included single element circular sources and rectangular shape tranducers that were representative of ultrasound imaging arrays u

A Fractured Future: climate change in an age of fossil fuel abundance [Audio]
Speaker(s): Lord Browne of Madingley | Editor's note: We appologise for the explicit language used in part of the question and answer session. In 1997, Lord Browne broke ranks with the rest of the oil industry and acknowledged the risk posed by the climate change. In this lecture he will reflect on the progress made since that speech, and the prospects for the future. John Browne is a former chief executive of BP.
