Predicting Volcanoes
The Open University's researcher in volcanoes, Hazel Rymer explains why the Poás volcano in Costa Rica is her favourite, and how evidence form previous experiments there has lead her to believe there may be an environmental crisis - similar to one in the 1990's - on it's way. There have been changes in gravity above Poás, and Hazel talks us through some experiments she will be undertaking in the future.

The Case against Student Aid

For decades, Federal Financial Aid (FFA) programs have been implemented and expanded to make higher education "affordable" for students. The ostensible merits are obvious: loans, grants, and work-study schemes allow students to purchase education without much need for cash or other sources of private funding — a supposed benefit to students who otherwise might not be able t

Collaborative design of structures using intelligent agents
The construction industry has a long tradition of collaborative working between the members of a construction project team. At the design stage, this has traditionally been based on physical meetings between representatives of the principal design disciplines. To aid these meetings, the information and communications technologies that are currently available have been utilised. These have yielded some success but are hampered by the problems posed by the use of heterogeneous software tools and t

1.3.1 Why are cells different?

Now let us go on with our story and assume that we have decided the time is right to have a baby. The primary requirement for conception is that healthy gametes should be produced. We shall therefore look first at how gametes are made, and then examine some of the factors affecting their quality. But we must start with an explanation of what gametes are, and what sets them apart from other kinds of cell. In other words, what makes gametes special? Gametes are the cells that fuse to form a new

9 Subordinate legislation

The time available to committees and the Scottish Parliament is limited. The Parliament sits on Tuesdays, Wednesdays and Thursdays. Committees will normally meet on a Tuesday or Wednesday (occasionally Monday). This means that it may not be possible to hear all detailed aspects of a particular area of legislation quickly. A system, similar to the one used in the UK Parliament, has therefore been developed to allow for the creation of subordinate legislation.

An Act of Parliament is refe

6.2 The hypothalamus as central regulator

Research in the past 30–40 years has established that the hypothalamus, which lies below the thalamus and above the optic nerve chiasma and the pituitary gland in the brain, fulfils all of the functions listed above, at least in part. The main function of the hypothalamus is homeostasis. Factors such as blood pressure, body temperature, fluid and electrolyte balance, and body weight are held to constant values called the set-points. Although set-points can vary over time, from day to

Creativity and VR Use
Creativity with its various processes is involved in all design actions. Creativity used in architectural design is different than creativity in other domains. However, creativity in general with its related cognition processes has no general theory. This research proposes certain activities of initial architectural design phases in which the role of activity is important. The research proceeds to present a case study of two architectural design studios in which a VR environment is employed in o

Understanding cancer: News from the frontline
This Oxford at Said seminar was dedicated to cancer research. Three researchers from the University of Oxford give insights into recent advances in the field of cancer cell biology, therapy and epidemiology. One in three people develop cancer, and one in five in Europe and North America die of the disease. Although environmental and lifestyle factors, for example smoking or sun exposure, affect the incidence of some cancer types, all human populations and many types of animal suffer from this di

The Future of the Euro

The problems of the eurozone are ultimately malinvestments. In Greece these days the struggle continues about who will ultimately foot the bill for these investments. During the early 2000s an expansionary monetary policy lowered interest rates artificially. Entrepreneurs financed investment projects that only looked profitable due to the low interest rates but were not sustained by real savin

2.4.3 Sulfur (S)

Most proteins contain about 1% sulfur, which occurs in the side-chains (R groups) of two of the protein-forming amino acids, methionine and cysteine.

Cysteine is particularly important in proteins such as collagen (found in bone, tendons, cartilage and skin) and keratin (found in hair and nails, as well as skin).

3.2 The anatomy of the language system

Perhaps the best-known generalisation about the language system is that it is represented on one side of the brain – usually the left – more than the other. Many lines of evidence support this view. Specific impairments to linguistic abilities are known as aphasia, and aphasia results much more often from damage to the left hemisphere of the brain than from damage to the right. It is also possible to temporarily deactivate one or other hemisphere. This is usually done as an investi

1.3 Marking decimals on a scale

Figure 2 shows a picture of a ruler. The major units are marked in centimetres (1 to 11 cm), whilst the intervals between the centimetres have each been split into ten equal, smaller units. These minor units are therefore tenths of a centimetre, commonly known as 'millimetres'. (There are 10 millimetres i

2.3.1 Thermodynamics and entropy

The first half of the nineteenth century was a period of great economic and industrial growth. The steam engine, invented in the previous century, was becoming increasingly common in locomotives, mines and factories; power was becoming available on demand. A major priority for engineers was to produce more efficient engines, in order to deliver more useful power for less expenditure on fuel. Thermodynamics emerged as a study of the basic principles determining energy flows and the effi
