1.2 Expressing ratios

To make short crust pastry, one recipe book says ‘use one part of fat to two parts of flour’; another recipe says ‘use fat and flour in the ratio of one to two’; and yet another says ‘use half as much fat as flour’. These are different ways of expressing the same ratio. Ratios are often expressed as fractions. So in this case:

9 What the world said – or, the politics of the exotic

So far we have mostly been concerned with the making of the Pavilion, treating it as a product of the confluence between the prince's virtuoso taste, his fluctuating reserves of cash and his patronage of the talents of a series of architects and designers, especially John Nash. We have also remarked in passing that the flamboyant idiosyncrasy of the Pavilion seems to be attributable in large part to the prince's nostalgia for absolutism, expressed in an era of constitutional monarchy and seem

Understanding Globalisation
What do we mean when we say globalisation? Does the growth of globalisation hinder or benefit mankind? It’s a common assumption that countries globalise but in fact it’s not nations themselves but rather the Industries and companies that trade within and outside their borders. As new forms of technology emerge and organisations expand they erode traditional boundaries and in recent times there has been a rise in interconnectedness of markets across the world.

2.3 Distinctive contributions

In Activity 1 you looked at the various support roles of Jean, a pupil support assistant. Let us now consider the essential nature of the work that assistants do and the way they contribute to the totality of work in a classroom.

Are teaching assistants ‘simply’ assisting teachers in doing their work? If this is so, it seems that teachers and assistants are working together to carry out the duties that previously teachers working alone would have covered. On this analysis, teaching

Kinematics of fluids
This free course examines the basic kinematics of two-dimensional fluid flows. Section 1 introduces the differential equations for pathlines and streamlines. Section 2 introduces a scalar field, called the stream function, which for an incompressible fluid provides an alternative method of modelling the flow and finding the streamlines. Sections 2 and 3 derive the stream functions for several simple two-dimensional flow types (the uniform flow, source, doublet and vortex), and suitable co

7 Ions and ionic bonding

This section returns to bonding - the way in which atoms are joined to each other. You have already met one type of bonding involving covalent bonds, which is found in molecules. However, this is not the only bonding found in compounds. In this section you will look at ionic bonding and the ionic compounds that contain such bonding. What is the main difference between the covalent compounds you met in Author(s): The Open University

6.1 London

London's population and economic size are those of a region. As such it contains various peripheries within itself. Further to this, there are some issues, mainly economic planning and transport, which are closely connected with the rest of south-east England. The Labour government introduced a Greater London Authority (Referendum) Bill in October 1997 and organised a referendum on 7 May 1998 in which 72 per cent voted (on a low turn-out of 33.5 per cent) in favour of establishing a Mayor and

9.00 Introduction to Psychology (MIT)
This course surveys questions about human behavior and mental life ranging from how you see to why you fall in love. The great controversies: nature and nurture, free will, consciousness, human differences, self and society. Students are exposed to the range of theoretical perspectives including biological, evolutionary, cognitive, and psychoanalytic. One of the best aspects of Psychology is that you are the subject matter. This makes it possible to do many demonstrations in lecture that allow y

6.2 Catalytic mechanisms

In general terms, the following mechanisms operate at the active site of an enzyme to bring about the conversion of substrate to product:

  1. Charged groups at the enzyme active site alter the distribution of electrons in the substrate. By affecting the electron distributions in key atoms in the substrate, the enzyme can destabilise existing bonds and favour the formation of new bonds. This principle is illustrated below, using as an example the hydrolysis

This Technical Paper describes the results of analyses of young children's cognitive progress during their time in pre-school. Equivalent results on social behavioural development are reported in EPPE Technical Paper 8b. Five measures of cognitive attainment assessed at entry to primary school have been studied: pre-reading, language attainment, two measures of non-verbal attainment and early number concepts.

5.3.1 Allosteric regulation

In many proteins, the binding of a particular ligand at one site affects the conformation of a second remote binding site for another ligand on the same protein. This effect is called allosteric regulation and it is an important mechanism by which a protein's binding capacity and/or its activity are regulated. Thus the switch between two different protein conformations can be controlled by binding of a regulatory ligand.
