Misoriented interphase boundary between h-BN and SiC grains
The micrograph shows misoriented interphase boundary between h-BN (precipitate) and SiC grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react wit
Introduction This unit is aimed at teachers who wish to review how they go about the practice of teaching maths, those who are considering becoming maths teachers, or those who are studying maths courses and would like to understand more about the teaching process. This unit is from our archive and is an adapted extract from Teaching mathematical thinking at Key Stage 3 (ME624) which is no longer taught by The Open University. If you want to study formally with us, you may wish to explore other cour
The Treaty of Versailles
Nearly one year after President Woodrow Wilson addressed Congress and laid out his Fourteen Points, fighting in Europe had reached its end. In the last weeks of the war, Wilson used the promise of his Fourteen Points to persuade the German people to overthrow Kaiser Wilhelm II and establish an armistice. Under the armistice, Germany had to withdraw behind the Rhine River and surrender its submarines and munitions.
To establish the conditions of surrender for the defeated Central Powers, me
The Busy World of Richard Scarry-Imagine That - Ancient Ruins
In this video Huckle and Lowly Worm learn about ancient ruins. A long time ago people built pyramids and statues and are now ruins. We can learn from ruins of how people lived long ago. Ruins are wonderful things to explore but they need to be kept safe. This is a good teaching resource for teaching about history and people of long ago. This video would work well in conjunction with a story on ancient times and is an additional resource to help build background knowledge for students (1:06)

1.1 A shared understanding All representations (including graphical ones) rely on shared understandings of symbols and styles to convey meaning. Like maps, graphical representations stress some features and ignore others. As you work through this course, bear in mind that graphs are selective representations of information. When you come across different graphs ask yourself what is being stressed and what is being ignored. In the newspapers, you are likely to find graphs used to present all sorts of information:
2.4 See what you can do on the web The web is immense, made up of information held on computers across the world. You can find out things about any subject or topic you care to name, however obscure it might be. The section entitled Searching later in this course provides advice and tips on searching the web and finding what you want.

6.1 Introduction As a student, you're likely to engage in a variety of writing tasks. You'll almost certainly handle significant amounts of text and, depending on your course, perhaps also numbers or diagrams. This section looks at the different way that you write using a computer, and also provides some referencing advice.
3.4 How does the EU operate? The EU operates through institutions created in the treaties. These institutions can have decision-making powers, law-making powers or may act as part of a checking and consultation procedure. The institutions include: The European Parliament (represents the people of the EU). The Council of the European Union (represents the member states of the EU). The European Commission (represents the interests of the EU).

3 Group axioms Section 3 is an audio section. We begin by defining the terms group, Abelian group and order of a group. We then demonstrate how to check the group axioms, and we extend the examples of groups that we use to include groups of numbers – the modular arithmetics, the integers and the real numbers.

How did we Reach the Present Crisis in Social Care and what are the Solutions? [Audio]
Speaker(s): Professor Pat Thane | The social and health needs of older people are not easily separable. But care has been institutionally separate since 1948. Did this help create the current crisis?

They were prominent in the Manchester Literary & Philosophical Society which Owen joined in 1793. There he associated with some significant reformers, heard papers on a wide range of intellectual, industrial and social topics, and himself presented papers dealing with such issues, including one on education. The society was founded in 1781, the co-founders b Crackdown in Syria An introduction: Sacking prime ministers Anisotropic thermal conductivity in quartz: parallel to c-axis section
