2.1 Introduction

As handovers can take place at many stages – not just the concluding stage – of a project, handover is not, in itself, completion of the project. If the project's objectives were clearly set out, the completion or acceptance criteria should flow logically from them. Such criteria might include the following:

  • the key stages and milestones are all completed;

  • the outputs or outcomes meet the quality specifications;

8.7 Evaluating strategy and presenting outcomes

This stage of the framework focuses on identifying what you have achieved and how well you have achieved it. It involves you in evaluating your strategy and presenting the outcomes of your work. As you evaluate and assess your strategy, identify aspects of your problem-solving skills that you want to develop further. At the end of this stage, use the records in your Skills File to complete the activity ‘Evaluating your problem-solving strategy and presenting outcomes’ and pull together th

4 From DNA to RNA: transcription

In the process of transcription, the information in a gene, i.e. the DNA base sequence, is copied, or transcribed, to form an RNA molecule. RNA is therefore an intermediary in the flow of information from DNA to protein. Before we consider the details of transcription, we will first look at the structure of RNA.

The name ribonucleic acid suggests that RNA is chemically related to DNA. Like DNA, RNA is a chain of nucleotides.

5 Biomass conversion of solar energy

Photosynthesis in the geological past was responsible for all fossil fuel reserves, but its products are buried about 2000 times more slowly than we use them at present. The total carbon content of all biomass growing on land is estimated to be 5.6 × 1014 kg and, as Figure 10 shows, about one-fifth of this mass is renewed each year. Figure 6 shows how modern plant biomass is distributed across the continents. Clearly, biological conversion of solar energy to a chemical form in com

4.1 Introduction

The focus of Section 3 was on LANs that use some kind of physical medium (for example, copper wires or fibre-optic cables) to connect together network nodes. In this section we'll be examining wireless networks – that is, networks that transmit data through the air (or space) using radio waves.

There's nothing new about wireless: the principles of transmitting information using radio waves were discovered over a century ago. However, using radio waves to provide the transmission links

Project drift

Project drift is a common problem when one project leads into another without a clear break, or when extra tasks, which were not identified at the beginning, are added to a project. If possible, significant changes of the latter kind should be treated separately as a follow-on project: otherwise they may not be properly resourced and this can have adverse consequences for motivation of the project team.

5.3 Summary

Common sense is a complex and contested phenomenon. The practice of systematic scepticism is a key aspect of social science, particularly in the analysis of common sense and the consideration of the social construction of social problems. Social constructionism emphasises the importance of social expectations in the analysis of taken-for-granted and apparently natural social processes. It starts by exploring the assumptions associated with the naming or labelling of things. It is sceptical ab

3.4.1 Calcium ions

The Ca2+ concentration is normally low in the cytosol (~10–7 mol 1–1) compared with the extracellular space (~10–3 mol 1−1). There are several mechanisms for achieving this. The most widespread are ATP-dependent Ca2+ efflux pumps on the plasma membrane, which pump Ca2+ ions out of the cell. Muscle and nerve cells, where oscillations in intracellular Ca2+ concentration often occur, employ an additio

Inuit Throat Singing
In many cultures, song is perhaps one of the most important traditions. What is extraordinary about the Inuit musical tradition is the way they create their songs - with notes originating from their throats. The song isn't interrupted even when a breath has to be taken. The 6 tracks in this album focus on Tanya Tagaq, who describes the amazing art of throat singing and how her heritage and culture, carried in her heart forever, has driven her to continue with this unique tradition.
