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

5.2 EU primary legislation

In Part B we learned that the different stages in the development of the EU have been marked by the adoption of intergovernmental documents called ‘treaties’. These are the first source of EU law and contain the founding legal acts. They contain the basic provisions and the majority of EU economic law. The treaties also create the decision- and legal rule-making powers of the EU institutions.

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

3.3 Specialisation within language areas: aphasia

Aphasia is caused by localised brain damage, for example due to a stroke or an automobile accident. General intellectual functioning is not necessarily impaired, as the person can still perform non-linguistic tasks. Nor is the understanding and production of language necessarily completely abolished. Instead, there are highly specific patterns of impairment in the way language is processed.

Aphasia is divided into two main types, fluent and non-fluent. For reasons which will become appa

3.5 The screening current

The London equations relate the magnetic field in a superconductor to the superconducting current density, and we derived the dependence of field on position by eliminating the current density. However, if we eliminate the magnetic field instead, we can derive the following equation for the current density:

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.

The PDZ Domain as a Complex Adaptive System
Specific protein associations define the wiring of protein interaction networks and thus control the organization and functioning of the cell as a whole. Peptide recognition by PDZ and other protein interaction domains represents one of the best-studied classes of specific protein associations. However, a mechanistic understanding of the relationship between selectivity and promiscuity commonly observed in the interactions mediated by peptide recognition modules as well as its functional meaning
