As the temperature continued to decrease, protons and neutrons were able to combine to make light nuclei. This marked the beginning of the period referred to as the era of primordial nucleosynthesis (which literally means 'making nuclei'). The first such reaction to become energetically favoured was that of a single proton and neutron combining

Social institutions affect which actions are seen as legitimate. As we make decisions in organisations it is common to be concerned not just with economic outcomes but also with â€˜legitimacy â€™: â€˜How will this decision be seen by X â€™?; â€˜Does this fit the way things are done around here?â€™; â€˜What would happen if the press got hold of this?â€™; and so on.

Some of this can be quite unconscious; the conceptual frameworks and notions of cause and effect that are available to decis

The constitutional dimension of the EU has been continuously developing. It is influenced by changes both in the membership of the EU and by a desire to develop and strengthen the EU. Part of this development is reflected in the negotiations towards the adoption of a new EU constitution. This part of the course has given you the opportunity to appreciate the complexity of this process. Whether the proposed new EU constitution merely consolidates existing legal provisions or whether it brings

On an autumnal morning in November 1994, a group of people gathered at Regent's College, London, conscious that they were making history. The purpose of the meeting was to discuss an important issue: plant biotechnology and how it should be regulated in the UK. At the time, the genetic engineering of plants was emerging as a technology of great potential for the development of new pest-resistant, higher yield crops, although the technique hadn't attracted the degree of media attention and pub

The EU is an economic, juridical and, to an extent, political reality. But is it a public space in the sense of an arena in which groups and individuals vigorously exchange symbolic messages of different types? It would appear as if, while the public of most EU countries are willing to accept ever closer economic union (including a common currency and even political convergence), when it comes to historical memories, social organisation and cultural ideas (including religion), they are mostly

In PECVD a plasma is initiated in the CVD chamber, usually by supplying an RF voltage to the platen on which the wafer sits â€“ the chamber geometry is similar to a reactive ion etch chamber. Ions are accelerated from this plasma onto the wafer surface, so that the CVD reaction is initiated not only by heating the wafer, but also by the energy imparted as the ions land. This allows high-quality film deposition at much lower wafer temperatures and higher deposition rates than unenhanced CVD, w

The notions of a final vocabulary and that of ideology are closely related. Anthony Giddens defined ideology as â€˜shared ideas or beliefs which serve to justify the interests of dominant groupsâ€™ (Giddens, 2006, p. 1020). There are all sorts of problems with this definition. One difficulty, for example, is that ideas and beliefs, if they have any kind of existence, are hidden away and have to be inferred by what people do and say. Another difficulty surrounds exactly how these things can be

Issues of 'fairness' and our obligations to the developing world do not in themselves explain why the issue of GM plants attracts such controversy. This section focuses on an episode in the fraught history of the development of GM foods that had a significant effect on public attitudes in the UK. In particular, we look at the experiments of Arpad Pusztai in the late 1990s at the Rowett Institute near Aberdeen, Scotland. These experiments are of particular interest to us because they reveal a

â€˜Careâ€™ is a loaded word. Care is not just about tender loving feelings, it is about work as well. Being seen as someone who needs care says something about a person â€“ their competence, their position in society, their status. This section explores those meanings.

In the poem which opened the unit, care is a warm â€˜feel goodâ€™ word, associated with what happens in nice families. But in the discussion of what a carer is in Section 1, it seemed that doing care was also hard work fo

A Format for a Graphical Communications Protocol
This article describes the requirements for a graphical format on which a graphical on-line communications protocol can be based. It is argued that on-line graphical communications is similar to graphical session capture, and thus the author proposes an interactive graphical communications format using the GKSM session metafile. The discussion includes items that complement the GKSM metafile such as a format for on-line interactive exchange. One key application area of such a format is multimedi

Something 's gotta give' architectural animations
Architectural animations are like Harry Langer, a fifty-something entertainment mogul played by best actor nominee Jack Nicholson in the film Something.s Gotta Give. They.ve been surrounded by plenty of pathetic spiritless gimmicks. And, like Harry in the film, they have suffered a heart attack. Harry did not die. Architectural animations are still around, barely. Something.s wrong with them. When Harry begins to recover, he.s surprised to find himself growing fond of a woman his own age (played

Managing the internal interfaces is part of the story. Of increasing importance is the management of the processes that cross organisational boundaries between suppliers and purchasers, that is, the management of the supply network or chain. This network of suppliers, customers, government agencies and others that are necessary parts of the entire value system must be proactively managed. This includes designing the network appropriately.

A supply network is defined as:

Reuse is the process of building new software from existing software assets, rather than starting from scratch. Reuse is an important factor in building flexible products that can be changed quickly in response to changes in requirements.

One of the advantages claimed of object technology is that it encourages a disciplined approach that facilitates reuse. Encapsulation encourages better designs that can be reused in a more reliable way, as there is exact knowledge of which oper
