2 High- to medium-enthalpy steam fields

When the geothermal gradient heats water above the temperature at which it boils at atmospheric pressure, at a depth accessible to drilling, conditions can favour using natural geothermal steam to generate electricity. Typically, the pressure can be several tens to hundreds of times that of the atmosphere. Even at 200 °C, high pressure can ensure that much of the fluid in a geothermally heated aquifer remains in the liquid state. Author(s): The Open University

6 Permeability

It is important to distinguish clearly between porosity and permeability. Porosity is a measure of how much water can be stored in a rock, whereas permeability is a measure of the properties of a rock which determine how easily water and other fluids can flow through it (see Section 4). Permeability depends on the extent to which p

5.3 The redshift of the 3 K radiation

The temperature, T, of the radiation is proportional to the most probable photon energy, E, which as we have said is proportional to f, and hence inversely proportional to the wavelength λ. Thus,

According to Equation 1, we have for the

2.2 Winning coal in former times

Coal was probably first used as a fuel by early Chinese civilizations, and there is evidence for coal working in the UK since Roman times. However, early approaches to mining were limited by the available technology, and left much of the coal behind.

At first, coal was dug from seams exposed at the surface in shallow excavations into valley sides that followed the coal seam. The amount of coal that could be extracted from these trenches and from adits (short horizontal tunnels) w

7.5 Summary of Section 7

  1. Site-directed mutagenesis is an important technique for studying protein function. Using recombinant DNA technology, selected amino acids can be substituted with different residues to alter the structure and function of a protein. One widely used method employs primer extension. SDM studies can help identify residues that are critical for interactions or catalytic activity.

  2. Protein–protein interactions can be studied in a number of different

Conclusion

  1. Eutrophication is a process in which an ecosystem accumulates mineral nutrients. It can occur naturally, but is usually associated with human activity that releases nutrients into the environment.

  2. Anthropogenic eutrophication has caused a widespread loss of biodiversity in many systems. Recent attempts to reverse the process are proving difficult and expensive.

  3. Symptoms of eutrophication are most readily seen in aquatic systems,

RVC 25 - The Role of Mitochondria in Health and Disease
Mitochondria are cell organelles which play a critical role in energy supply in most higher organisms. But how did that role develop and how do they achieve this function? In the latest episode of the RVC Podcast Dr Michelangelo Campanella discusses these questions and relates his research findings on how poor mitochondrial function can contribute greatly to disease processes.

5.9 Membrane filtration

Membrane filtration is a process whereby particles smaller than about 10−2 mm (which can pass through sand filters) are removed using synthetic polymeric membranes and a high pressure. The membrane effectively acts as a sieve.

It is increasingly becoming popular as an advanced treatment process for water (especially for removal of Cryptosporidium) and wastewater (where water reuse takes place), and various possibilities are:

7.340 Immune Evasion: How Sneaky Pathogens Avoid Host Surveillance (MIT)
Every infection consists of a battle between the invading pathogen and the resisting host. To be successful, a pathogen must escape the many defenses of the host immune system until it can replicate and spread to another host. A pathogen must prevent one of three stages of immune function: detection, activation, or effector function. Examples of disease-specific immune evasion and the mechanisms used by pathogens to prevail over their hosts' immune systems are discussed. Also considered is what

4.5 A critique of substantial equivalence

In the late 1990s, the principle of substantial equivalence came under sustained attack, and at this point it is worth examining both the points of criticism and the responses. In October 1999, Erik Millstone, Eric Brunner and Sue Mayer published a critical commentary on substantial equivalence in the journal Nature.

Before you read some extracts from this article it is worth commenting both on the nature of the article and who the authors are. The article is a 'commentary' publi

2.5 Wavelength

So far we have seen that sound is a pressure wave, and that the spacing of the pressure variations is related to the period of vibration of the source.

A graphical representation of the pressure wave from a tuning fork closely approximates to a certain type of wave known as a sine wave.

If we freeze the pressure wave as a snap shot in time, the variations in pressure with distance from the tuning fork can be plotted as a sine wave. The vertical axis is pressure so the crest
