You will probably think to yourself that the coat shown costs about Â£300. Â£290 is considerably closer to Â£300 than it is to Â£200, so Â£300 is a reasonable approximation. In this case, 290 has been rounded up to 300. Similarly, 208 would be rounded down to 200 because it is closer to 200 than it is to 300. Both numbers have been rounded to the nearest hundred pounds.

When rounding to the nearest hundred, anything below fifty rounds down. So 248 rounds to 200. Anything o

Key skills underpin almost everything we do. In the following table, there are some examples of when we use key skills as part of our studies or in other areas of our lives. As you read through the list, think about how confident you are in each of the key skills.

Linguistic Operation System for Design of Architectural Form
In a process of architectural design, an architect not only draws by himself/herself but also lets another person modify a design by given a linguistic instruction expressing how the design ought to be. In the case of utilization of CAD systems, it is useful if the system modifies the design according to the linguistic instruction. On the other hand, because of the recent increase of the opportunities of designing a building whose roof has complicated curved surface, it extremely takes labor to

The second of the conjugateâ€“modulus properties enables us to find reciprocals of complex numbers and to divide one complex number by another, as shown in the next example. As for real numbers, we cannot find a reciprocal of zero, nor divide any complex number by zero.

Now think about adding a negative number, by looking at the number line again. Suppose you start at 0. Since 0 + âˆ’3 is the same as âˆ’3, you would expect that adding âˆ’3 to 0 on the number line should take you to the point marked âˆ’3 on the number line. So, 0 + âˆ’3 = âˆ’3.

Suppose Thomas's piggy bank were empty and he added an IOU for Â£3 to it. The value of the piggy bank would be âˆ’3.

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

The collapse of socialism didn't deter the Marxists, who moved on to invent new rationales for their system. But David Gordon has caught up with them, and used the knife of the Austrian School to cut their theories to pieces. A masterful demonstration of philosophical technique. The book in particular addresses the arguments of the analytical Marxists: G.A. Cohen, Jon Elster, and John Roemer.

The application of site-directed mutagenesis (SDM) to the study of protein function has been illustrated with the enzyme lysozyme, as described previously. SDM is a very powerful technique in the study of protein function, allowing the experimenter to assess the importance of particular amino acid side-chains in a protein. It is most commonly used in the study of enzymes; however, it is also very useful in identifying key residues in proteinâ€“protein interactions. In this section, we will co

Gestational diabetes is diabetes that develops during pregnancy. There are no internationally agreed threshold blood glucose levels used to diagnose gestational diabetes. However, there is a trend towards using the IGT (impaired glucose tolerance) test criteria (see Section 4). Studies are ongoing to decide what threshold level is important i

Open-loop is the crudest way of controlling etch depth. It relies on ensuring that every aspect of the process that can affect the rate of progress of the etch is kept under tight control. This can add up to a sizeable list. Table 5 shows just some parameters that affect both wet and dry etching.

So what are the reasons for the continued growth in the use of polymers as shown in Figure 1? It cannot be raw material cost, since the source of synthetic polymers is crude oil or natural gas, prices of which have risen over the same period of time. The comparative prices of polymers are considerably greater than traditional ma

So far we have been considering aspects of Thugga without taking into account the chronology of the site and its monuments. The following table lists the public buildings and monuments of Thugga which are securely dated by inscriptions and gives the date (as near as possible) of construction along with an assessment of how African or Roman they are.

Reactivity is not spread evenly over a molecule; it tends to be concentrated at particular sites. The consequences of this idea are apparent in the chemistry of many elements. However, in organic chemistry, the idea has proved so valuable that it receives specific recognition through the concept of the functional group. Structure 6.1 shows the abbreviated structural formula of hexan-1-ol, an alcohol.
