2.2.2 Hollow tubing surfaces

In their doughnut-shaped representation, toruses can be thought of as being hollow tubes. Many other surfaces in space can also be drawn as if they were made of hollow tubing. Figure 15 shows two such examples.

7.3.1 Finding the 2's complement

In Section 2.4 you saw how to find the 2's complement representation of any given positive or negative denary integer, but it is also useful to be able to find the additive inverse of a 2's complement integer without going into and out of denary. For instance, 1111 1100 (−4) is the additive inverse, or 2's complement, of 0000 0100 (+4), but how does one find the additive inverse without converting both binary integers to their denary equivalents?

The answer is that the additive inve

2.6 Summary of Section 2

The results of the visual attention experiments we have considered can be interpreted as follows.

  • Attention can be directed selectively towards different areas of the visual field, without the need to re-focus.

  • The inability to report much detail from brief, masked visual displays appears to be linked to the need to assemble the various information components.

  • The visual information is captured in parallel, but assemb

Exploring the medicine experiences and needs of patients who are underserved
This e-learning resource has been co-produced with patients who belong to one or more under-served group. By listening to these individuals, it is intended that we can better understand their day-to-day circumstance and so better develop a sense of empathy with them. This will help encourage us to be consciously aware of individuals who are potentially most in need of support.

3.2 Io

Io is one of the most marvellous bodies in the Solar System, but the intense radiation bathing its surface (Figure 2) makes it unlikely that anyone will ever be able to visit. Even robotic spacecraft cannot survive this close to Jupiter for very long, so the Galileo Jupiter orbiter made very few close fly-bys of Io.

2.2 Population screening for genetic disease: the precedents

Knowing about particular genes, or their effects, also permits screening – the search in a population for persons with certain genotypes that are associated with a particular disease. Thus the test may be offered to one and all. Until now, screening programmes have focused on one gene at a time, or one disease at a time, in cases where a mutated gene poses serious health problems and something can be done for those who are found to carry the mutation. What that something is varies with the

5.5 Experiences that motivated the development of systems methods

I have already introduced various systems methods. Behind all of these methods, there has generally been a champion, a promoter aided by countless co-workers, students, etc. To paraphrase the French sociologist of technology, Bruno Latour: we are never confronted with a systems method, but with a gamut of weaker and stronger associations; thus understanding what a method is, is the same task as understanding who the people are.

A method, like any social technology, depends on many peopl

7.3 Running the models forward

What happens when the models are run forward? It depends upon the models used and the scenarios they are asked to run. It seems almost certain, however, that there will be increases in the global mean surface temperature, to the order of +1.5 to +4.5 °C (– possibly more, according to some models and scenarios.

These changes are predicted to be associated with increases in sea level, changes to weather conditions (e.g. more regular and violent winter storms in the UK) and changes to t
