6.4 Summary Amplitude refers to the size of a sine wave. It can be defined in various ways, but a standard definition is that it is the maximum value of a wave's departure from its average value. (The average value of a sine wave lies midway between its peaks and troughs.) The size of a sine wave is sometimes also expressed as a peak-to-peak amplitude, which is the vertical distance from peak to trough. Root-mean-square (r.m.s.) amplitude is a way of specifying the size of a sine wave so that compa
1.4.4 Case study 1: Vic Harris – a hospital death Vic was a 68-year-old man with a long history of chronic (pulmonary) obstructive airways disease and was therefore a regular in-patient at the medical ward of the local hospital where he received treatment. Vic had been on Crawford Ward for two weeks and was feeling very concerned that he was not making any progress. Previously he had experienced quite a marked improvement after a few days’ treatment but this time, instead of improving, his breathlessness and lethargy were getting worse and
5.7 Relating individual rights to state sovereignty The fourth set of problems is really a specific example of the third set and relates to the ways in which individual rights relate to state sovereignty. The Millennium Conference of the UN in 2000 endorsed the need for people-centred changes to the institution and renounced its previous ‘state-centred’ structure.

References 3.3 The Earth's internal heat The occurrence of both volcanoes and hot springs shows that the Earth's interior is hot, producing molten rock at temperatures up to 1250 °C, and also superheated steam. However, these phenomena are mainly confined to several narrow zones along the world's active plate boundaries. Many measurements have now been made of the amount of heat flowing from the Earth's interior. Outside the distinctive zones mentioned above, heat flow varies from 40-120 milliwatts per square metre (mW m−2 Intro to Judaism terms #11 Kashrut 1.7.4: Is a picture worth a thousand words? This final subsection is an overview of the various modes of mathematical communication used so far, like words, tables and graphs, and diagrams. You may have a preference for one over the others as a way of presenting ideas and of receiving information. However, they can all aid your understanding and communication of different mathematical ideas. So you need to develop your skills in using and interpreting all of them.

Part of the logic behind the emphasis on military painting, therefore, was the assumption that feats of arms and works of art both testified to the glory of Napoleonic rule. Traditionally, however, the most prestigious art form was the classical history painting, exemplified by David's Oath of the Horatii Georgians call on government to resign McCarthyism 4.2 Effect of the ECHR on English law prior to the Human Rights Act 1998 The Human Rights Act 1998 (HRA) received the Royal Assent on 9 November 1998, and the main provisions were brought into effect on 2 October 2000. However, the UK had by then been a signatory to and had ratified the ECHR for nearly fifty years. What was the effect, if any, of the Convention on UK domestic law? We have already noted the supremacy of Parliament as the main law-making body in the UK. Under English law international treaties do not become part of domestic law unless and until some Season 3 – Lesson 31 – Coffee Break Spanish It’s destination Colombia for lesson 31 as Mark is joined by Carolina from Bogotá.
