    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

    11.3 Memory

    An essential component of a computer is the memory which it uses to hold data currently being used by the processor. This is the random access memory (RAM), the computer's working memory in which programs and data are stored so that they can be accessed very quickly by the processor. The processor stores data in RAM and retrieves data from it as it carries out its manipulations. The more RAM a computer has, the faster the computer programs will run. RAM memory is used and reused and an

    3.4 Specialisation within language areas: brain scanning

    Is there any evidence from the undamaged brain that the view derived from aphasia is indeed correct? The most useful methodologies here use either PET or functional MRI (fMRI) scanning to establish which parts of the brain are active in particular tasks. The difficulty is that a standard linguistic task, such as understanding a sentence's meaning, involves phonology and syntax and semantics, and thus is not helpful when trying to tease out which of these subtasks happens in which areas.

    6 Thermoregulation and mammalian fur

    A coat of profuse mammalian body hair is commonly called fur. Fur provides insulation, which is a property that one first thinks of as useful for mammals to help retain body heat. Fur is a unique and fundamental feature of mammals, though not all living species possess it.

    1.5 How to take notes

    So what should you do when taking notes? Again you will develop your own technique, but the method I use is as follows. I read the material through once very quickly, from start to finish. I then sift through the material, writing the words or phrases I think are important. I usually do this on a word processor but you can just as easily use pen and paper. Avoid simply copying and pasting large chunks of material. It is the process of actively reading the material and putting it in your own w

    Introduction

    An essential aspect of maintaining the body is the consumption of food. The range of foods that we eat is known as our diet and the components of food that are digested, absorbed and used in bodily functions are known as nutrients. Nutrients supply the body with both energy and with the components for growth and repair. In this free course, Obesity: balanced diets and treatment, you will examine the various roles of nutrients within the body and look at the effects of nut
