Scope and limitations of democracy
Challenging Democracy - 9th Dialogue on Science of the Academia Engelberg Foundation 2010 In a role play, participants assumed the task of governing different countries such as Germany, Canada, Kenya, Columbia, Pakistan and Serbia. On the one hand, they had the task to increase their country’s prosperity through fishing as the only source of income. On the other hand, they had to be careful to not lose the favour of the voters. This situation confronted several "governments" with real problem

1.8 Protein–protein interactions in signal transduction

Many signalling proteins have both a catalytic domain and sometimes several binding domains.Some only have binding domains, enabling their proteins to act as adaptor, scaffold or anchoring proteins to bring other proteins together. Because of this multiplicity of binding domains, signalling proteins can potentially combine to form complexes with many other proteins; these complexes may be either transient (e.g. in response to stimulation by a growth factor), or stable (to target a protein to

3.4.7 Induced earthquakes

Some reservoirs cause earthquakes to occur. This is perhaps not so surprising, as earthquakes are caused by stress in rocks, and the addition of a large mass of water in a reservoir on top of the rocks at the Earth's surface stresses the rocks and can trigger an earthquake. Not all reservoirs induce earthquakes: it is in general only the larger reservoirs, or the deeper ones (over 100m deep), and only if the reservoir is built in an earthquake area, releasing stress already stored in t

USA vs USSR: The Cold War: Crash Course World History, #39
In which John Green teaches you about the Cold War, which was occasionally hot, but on average, it was cool. In the sense of its temperature. It was by no means cool, man. After World War II, there were basically two big geopolitical powers left to divide up the world. And divide they did. The United States and the Soviet Union divvied up Europe in the aftermath of the war, and then proceeded to spend the next 45 years fighting over the rest of the world. It was the great ideological struggle, w

5.5 Other forms of diabetes

By far the three most common types of diabetes are Type 1, Type 2 and gestational. There are other forms of diabetes but we will not be covering them in any more detail. These are forms due to:

  • disease of the pancreas (pancreatitis)

  • an excess of hormones that increase blood glucose levels, e.g. excess growth hormone

  • drugs, for example, steroid therapy, which tend to oppose the action of insulin

  • abnorm

4.1 Introduction

Nuclear power generation involves concentrated fissionable fuels which, after fission, leave significant quantities of fission-product isotopes, some of which are highly radioactive. Much of the criticism levelled against the industry falls under four main headings to which we have alluded in preceding sections:

  1. the operational safety of nuclear reactors;

  2. the biological effects of abnormal radiation levels arising from fuel transport,

2.6 Summary

Ecology is the study of the interactions between organisms and their environment (including other organisms). An understanding of ecology is important to inform environmental decision-making.

Soil pH influences the availability of mineral nutrients to plants and hence the distribution of different plant species. Some species may be classified as either calcicoles or calcifuges.

Variation in salinity, exposure to desiccation and biotic interactions (e.g. grazing) influence the zona

5.10 Bridge stability

Any fracture of the diagonal wind brace tie bars could allow substantial lateral movement at the top of the piers. If these tie bars had already been injured by the previous train to cross the bridge, it would have only taken a little extra effort to complete the process as the mail train arrived over each pier supporting the high girders. Once the wind braces had failed completely, and the struts fractured at their connections each pier would behave as two separate supporting structures.

1.6 The human impact on the atmosphere: the coming of the industrial age

There is no doubt that CO2 is accumulating in the atmosphere. The record from Mauna Loa charts a continuing rise in CO2 concentration since measurements began in 1958, when the level was 315 ppm; the value had reached about 370 ppm by the end of the 20th century, and hit more than 378 ppm in 2004. Important as changes in atmospheric CO2 undoubtedly are (see below), we need to be aware that this is not the whole story of human-induced greenhouse forcing. In par

8.3 The AND operation

The AND operation combines two binary words bit by bit according to the rules

  • 0 AND 0 = 0

  • 0 AND 1 = 0

  • 1 AND 0 = 0

  • 1 AND 1 = 1

In other words, only when both bits are 1 is the result 1. You may find it helpful to think of it this way: when one bit is one and the other bit is 1 the result is 1.
