2.3.1 Geological mapping of coalfields

Coalfields can be divided into two categories: exposed coalfields, where the coal-bearing strata outcrop at the surface, and concealed coalfields, where they are hidden beneath younger rocks. Exposed coalfields can be defined with considerable precision by surface geological investigations; indeed geologists recording field data still represent the cheapest exploration 'tool' available to the coal industry.

In populated regions, the locations of coal outcrops are well know

1.1 Introduction

There are many environmental reasons why coal is a rather undesirable source of energy. Burning it introduces large amounts of gases into the atmosphere that harm the environment in a variety of ways, as well as other, solid waste products. Coal extraction leads to spoil heaps and mines that scar the landscape, land subsidence that affects roads and buildings, and in some cases water pollution.

With apparently so little going for it, why do we rely so much on coal to meet our energy nee

2.6 Underground mining

Coal extraction is of course less straightforward using underground mining techniques. The associated costs are higher, and these begin with the sinking of two shafts, an 'upcast' and a 'downcast' shaft for ventilation (Figure 22). Sinking these to a depth of a kilometre may take a few years and during this time,

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

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
