4.6 Plants as medicines

Plants are already a major source of medicines. In 1990, sales in the USA of prescriptions where material of plant origin was the active ingredient totalled US$141500 million. For many centuries, people around the world have relied on herbal remedies of various kinds in the prevention and cure of ailments and diseases. There are over 211000 medicinal plants named by the World Health Organisation. Although there is some duplication where plants are known by different names in different places,

7 Conclusion

One might think of the different interpretations of internationally recognised notions of rights and justice as running along a spectrum, from which we shall now identify four different positions.

  • The first interpretation would argue that, overall, the extension of rights to the international sphere has been benign and effective. It has led and will lead to further successful claims for justice.

2.8 Surface run-off

In some inland drainage areas, all water is removed by evaporation and infiltration. However, precipitation not penetrating the land surface usually runs off the surface along defined channels which have been produced by geological processes, previous storms, or possibly by people. This accelerates the process. Its eventual destination is the ocean, except, of course, where it runs to inland seas such as the Dead Sea. It is in the runoff phase of the cycle that physical intervention by humans

Conclusion

You have now had an opportunity to examine the poetry of Sorley MacLean. This should have helped you gain an increased sense of the power of MacLean's poetry both in the English and in its original Gaelic.

The provision of the English translations and the discussion by the poet himself during the interview with Ian Crichton-Smith should have increased your understanding of the English texts.

5.2 Background to Theory of the Earth

The two volumes of Theory of the Earth embody a startlingly original conception of the processes which shape the earth's surface, and they contain some vivid observations, drawn from Hutton's travels. However, they are poorly organised, repetitive and sometimes obscure. In a most helpful survey of Hutton's work, from which this section draws liberally, Jean Jones quotes from a wonderfully direct letter that a saddlesore Hutton wrote while on a field-trip in Wales: ‘Lord pity the arse

6.2 Street photography

Many portraits were taken outside the home and in the garden or, in the case of urban dwellers, in the street or back yard. Local studio proprietors could be commissioned to attend at the customer's house, in which case they would impose an additional charge to cover the extra time and effort involved. Itinerant operators regularly patrolled suburban streets and villages in search of speculative work. Their prices undercut those on offer in local studios. Weekdays would find women, children a

Millions of care relationships are going on as you read this, and each carries its own particular meanings for those involved. But where have all those people picked up their ideas of how to relate to each other? How does any of us know where to

3.1 ‘Making ends meet’

When you say that someone is ‘poor’, what do you mean?

Do people whom others call ‘poor’ always see themselves in that way?

One group whose identities are greatly constrained by income are the poor. But, as the questions above suggest, poverty is not a simple fact of some lives: rather, it is a concept with different meanings, and a label that we may accept or reject. This section c

Introduction

This course looks at identity, focusing upon the individual's perception of self in relation to others; the relationships between multi-ethnicity, cultural diversity and identity; and the effects of inequality and social class upon identity. It also looks at inequality and social class as they relate to perceived identity.

7.3 Subtracting 2's complement integers

You will probably have carried out subtraction of denary numbers using rules for subtraction that include the process of ‘borrowing’ whenever you need to subtract a larger digit from a smaller one. It is possible to perform binary subtraction in a very similar way, but that is not what happens in computers. The processor contains the circuits needed to perform addition, and it is much more efficient to use these circuits also to perform subtraction than it is to build in extra circuits to

6.2.3 E-procurement

‘Procurement’ is the term used to describe the tendering of goods and services: a company decides that it requires some goods, say a fleet of cars for its salesforce. It would then announce this publicly and invite a number of auto companies to bid for the business.

Many companies are now switching to the web for the procurement process. A website devoted to procurement will normally advertise current procurement opportunities, provide forms facilities for companies interested in te
