2.7.1 Recognizing geological problems

The most profitable coal mines are those that possess unbroken, horizontal seams of constant thickness and quality. In mines where this is not so, profit levels will depend on the ability of the mine geologist to predict changes in the seam before they are encountered at the face.

Geological problems fall into two categories — gradual changes and sudden changes. Where a change is gradual, such as a seam thinning or splitting, data from boreholes in advance of the workings, supplemente

4.3 A commercial implementation

In order to conclude this section I shall describe a commercial implementation of an object bus. It has been developed by a company known as SoftWired Ltd and is known as iBus. It is based on TCP/IP rather than UDP. The facilities offered by the iBus API provide developers with the facilities to construct objects which can subscribe to channels and to transmit any Java object to a channel. The code for a transmitter is shown below; the import statements are not shown. In

2.4 Critical magnetic field

An important characteristic of a superconductor is that its normal resistance is restored if a sufficiently large magnetic field is applied. The nature of this transition to the normal state depends on the shape of the superconductor and the orientation of the magnetic field, and it is also different for pure elements and for alloys. In this subsection we describe the behaviour in the simplest situation; we shall discuss other more complex behaviour in Section 4.

Occult Features of Anarchism: with attention to the conspiracy of kings and the conspiracy of the pe
Speaker(s): Dr Erica Lagalisse | Erica Lagalisse explores the relationship of 19th century anarchism with the clandestine fraternity, challenges leftist attachments to atheism, and intervenes in current debates concerning “conspiracy theory”. In the nineteenth century anarchists were accused of conspiracy by governments afraid of revolution, but in the current century various “conspiracy theories” suggest that anarchists are controlled by government itself. The Illuminati were a network

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
