4.1 Overview

For a small country whose population has never been much in excess of five million, Scotland seems to have more than its fair share of famous men and women. Native Scots or those descended directly from them have been the recipients of some 11 per cent of all the Nobel Prizes that have been awarded.

In this section of the OpenLearn Scotland collection, we look in detail at the lives and work of four great Scots: John Napier, James Clerk Maxwell, Robert Owen and David Hume.

Poly (lactic-co-glycolic acid) (PLGA) porous scaffold for tissue engineering. Enlargement of a Pore.
The patients own cells are seeded onto the scaffold and allowed to attach and start producing new bone. The construct is implanted into the defect site, where eventually the polymer will biodegrade and be completely removed, leaving a natural autogenous bone graft. This technique is particularly useful for large defects, or where the host bed is compromised due to disease, although it is still at the research stage. Average Pore Size 350-550 micrometre, porosity estimated at 35-45%.

1.1 Why does it hurt?

The relief or avoidance of pain must be one of the major driving forces behind medical research. In this course we start the discussion about relief of pain.

When we experience the sensation of pain it is likely that something is happening that the brain needs to know about, so it can direct us to whatever damage-limiting action is needed. We hurt because we have genes that constructed a body able to feel pain.

Without such a mechanism it is likely that life would be much shorter,

Normal galaxies

Figure 8 shows schematically the broadband spectrum of a normal spiral galaxy. It resembles that of the Sun, although the peak occurs at a slightly longer wavelength and there are relatively greater spectral flux densities at X-ray, infrared and radio wavelengths.

3.4 Radio galaxies

Radio galaxies were discovered accidentally by wartime radar engineers in the 1940s, although it took another decade for them to be properly studied by the new science of radio astronomy. Radio galaxies dominate the sky at radio wavelengths. They show enormous regions of radio emission outside the visible extent of the host galaxy - usually these radio lobes occur in pairs.

The first radio galaxy to be discovered, and still the brightest, is called Cygnus A (Author(s): The Open University

1.5.7 Referencing

We mentioned above that we need to reference sources to ensure we abide by copyright legislation. But there is another reason we need to give accurate references to items we use - so we can share it.

Consider this scenario. A friend says they've just read an interesting article where Joshua Schachter, founder of Delicious has spoken about why it isn't a faceted search system, and you should read it. How would you go about finding it? Would you start looking in a news database, a search

Elizabeth Gilbert at TED "Nurturing Creativity"
Excellent video for writers of all ages. It really enforces the importance of hard work and dedication in the arts. Lecture format.

"Elizabeth Gilbert muses on the impossible things we expect from artists and geniuses -- and shares the radical idea that, instead of the rare person "being" a genius, all of us "have" a genius. It's a funny, personal and surprisingly moving talk."
Run time 19:32.

2.1 Chemical periodicity

The chemistry of the elements is immensely varied. But amidst that variety there are patterns, and the best known and most useful is chemical periodicity: if the elements are laid out in order of atomic number, similar elements occur at regular intervals.

The discovery of chemical periodicity is particularly associated with the nineteenth-century Russian chemist Dmitri Ivanovich Mendeléev (Figure 16). The periodicity is represented graphically by Periodic Tables. Author(s): The Open University

2.2.1 Positive integers: denary numbers

The number system which we all use in everyday life is called the denary representation, or sometimes the decimal representation, of numbers. In this system, the ten digits 0 to 9 are used, either singly or in ordered groups. The important point for you to grasp is that when the digits are used in ordered groups, each digit is understood to have a weighting. For example, consider the denary number 549. Here 5 has the weighting of hundreds, 4 has the weighting of tens and

3.4 Evaluation at the end of a project

Different types of evaluation may take place at the end of a project. A common one is determining the extent to which the project outcomes have been achieved. This is often done in a meeting of the sponsor, key stakeholders and project team leaders, and sometimes informed by reports from key perspectives. An evaluation of this nature may be the final stage of the project, and the main purpose might be to ensure that the project has met all of the contracted expectations and can be ‘signed o

2.4 Collecting quantitative data

How can you collect quantitative data that summarise the nature of a habitat when it is three-dimensional? How, in fact, do you collect quantitative data?

Multi-storied habitats where the components have a different scale are usually recorded storey by storey, but using much the same methodology. There are two standard ways of collecting data quantitatively. The first involves recording species present within a standard area such as 10 cm × 10 cm, 0.5 m × 0.5 m, 1 m × 1 m, or 10 m ×
