A great advantage of the metric system of units is that conversion between units within the system is particularly easy. For example, â€˜Â£1 is worth 100pâ€™ is converting one pound into pence. To convert pounds to pence, you multiply by 100. So Â£2 is 200p, and Â£2.63 is 263p. (Remember that to multiply by 100, you move the digits two places to the left in the place value table.)

To convert from pence to pounds, you need to reverse this process, i.e. to divide by 100 (moving the

A rising demand for helium?
Fundamentally there is a certain irony that a material that is so important for a future low-carbon society is itself a by-product of natural gas. Without a fossil fuel industry what would we do for helium? Dr William Nuttall considers the implications of helium supplies and demands.

## 7.2.1 How do I find the information required to carry out COSHH risk assessments?

The best source of information is the material safety data sheet (MSDS). By law (CHIP3) this should accompany any chemical that is purchased. However, if this is not available, or the chemical is old, then copies can be obtained from the manufacturer's website or information can sometimes be found in the

After studying this unit you should be able to:

• explain what is meant by isotopes, atomic numbers and mass numbers of the atoms of chemical elements by referring to the Rutherford model of the atom;

• give an example of how differences in the molecular structures of chemical compounds give rise to differences in macroscopic properties;

• given a Periodic Table, point to some sets of elements with similar chemistry and to others in which there are progre

Watch more films from 1914 on the BFI Player: http://bit.ly/1pffvkP Filmed just a few months into WWI, this newsreel shows recruits of Kitchener's New Army rather haphazardly 'falling in' to formation for a parade. These recruits aren't professional soldiers but ordinary working men with little or no military training. Predicting a drawn-out war, Kitchener famously launched a patriotic recruitmen

For very thin conformal films, where rate is unimportant but precise thickness control is critical, a form of CVD allows deposition one monolayer at a time. One precursor gas is introduced into the chamber, which is then pumped away leaving only a monolayer adsorbed onto the wafer and chamber walls. The second precursor gas can then be supplied to complete the reaction at the surface, and then this gas is pumped away along with any gaseous reaction products. This cycle is repeated several tim

Message passing is the simplest form of development paradigm. For example, the way that a client running a browser communicates with a web server is via message passing.

Message passing is based on the idea of a protocol: a language which embodies the functions required by one entity in a distributed system (usually a client) which another entity provides (usually a server). As an example of a protocol consider Table 1. It shows the protocol associated with a naming servi

Revision is not, as the word suggests, simply 'looking again' at the material covered in a course - it is a more active task. It involves organising material and finding ways of remembering it, that suit your own particular learning style. Although the time you set aside for revision is important, the approach you adopt and the techniques you use to revise are more vital. Sometimes the thought of having to revise can seem daunting, but be reassured, revision skills and techniques can be learn

The two most successful species of omnivore - humans and the brown (or Norwegian) rat - both arose within mammalian groups that are not particularly omnivorous. Most members of our own family, the primates, are exclusively or predominantly herbivorous. However, chimpanzees do occasionally hunt and eat monkeys and the human species is far from being exclusively vegetarian. Brown rats are rodents and almost all rodents use their continuously growing incisors to feed on seeds, nuts, grass, stems
