Public sector pay freezes
NHS managers may well have to bite the bullet and accept a pay freeze in the coming year, but if it is executed in the right way and shown to benefit the NHS it may not demotivate staff. The right leadership is key to implementing such top down decisions that directly impact on people's pay, lifestyles and pensions, argues Dr Jenny Dean, but if NHS leaders engage with managers to make them see the longer term benefits it will make any freeze easier to shoulder.

1.3.8 Diagrams for communication

Commonly used diagrams for communication follow conventions that are widely understood, many diagrams used for connectivity as previously discussed also lend themselves to use in communicating ideas. A diagram developed for communication:

  • is large, clear and well laid out;

  • has shading and/or colour for emphasis;

  • has a title; and

  • has a key to the meaning of all the symbols used in the diagram.

Survival Rivals
Wellcome Trust have developed these secondary school level educational resources as part of Darwin 200, a national programme of events which honour Darwin’s scientific ideas and their impact. The resources comprise hands-on experiments which are available free and which are designed to assist young people to view how Darwin’s ideas are connected to modern evolutionary principles and contemporary biomedicine. The three resources include ‘I’m a worm, get me out of here’ for 11-14 year olds ex

1.7.1 Carboniferous mires

During the late Carboniferous, mires developed over vast areas of the UK. Much of today's land area was an extensive, low-lying plain bordering a sea to the south (a sea that was soon to be the site of a mountain-building episode). Any mountains that existed lay hundreds of kilometres to the north. Large river systems meandered southwards across these plains.

At that time, the UK lay in tropical latitudes, almost on the Equator (see Author(s): The Open University

2.4 Fuel requirements for nuclear reactors

The fission energy of uranium-235 is 8.2 × 1013 J kg−1. Setting this figure in the context of fuelling a reactor depends on:

  1. The thermal efficiency of the reactor — For modern burner reactors, this is similar to that of modern fossil fuel power stations, about 35% (i.e. 65% of the available energy is lost within the reactor-coolant-turbine system).

  2. The power output — A typical value for a bur

1.3 Scales of measurement

In thinking about the sizes of things, it is sometimes useful to do so in quite rough terms, just to the nearest power of ten. For example, 200 is nearer to 100 than it is to 1000, but 850 is nearer to 1000 than it is to 100. So if we were approximating to the nearest power of ten we could say 200 was roughly 102, but 850 was roughly 103. This process is called reducing the numbers to the nearest order of magnitude.

Powering the Planet: The Challenge for Science in the 21st Century
The supply of secure, clean, sustainable energy is arguably the most important scientific and technical challenge facing humanity in the 21st century. Rising living standards of a growing world population will cause global energy consumption to increase dramatically over the next half century. Within our lifetimes, energy consumption will increase at least two-fold. This additional energy needed is not attainable from long discussed sources, the global appetite for energy is simply too much. Pet

Conclusion

  1. Eutrophication is a process in which an ecosystem accumulates mineral nutrients. It can occur naturally, but is usually associated with human activity that releases nutrients into the environment.

  2. Anthropogenic eutrophication has caused a widespread loss of biodiversity in many systems. Recent attempts to reverse the process are proving difficult and expensive.

  3. Symptoms of eutrophication are most readily seen in aquatic systems,
