4.2 Reactor safety: the Chernobyl incident

By far the worst nuclear reactor accident took place on 26 April 1986 when one of four 1 GW reactors at Chernobyl in the Ukraine released a radioactive cloud over Europe (Figure 17). (See S278 video clips document.) The build-up to this accident has been related to a series of complex chemical reactions induced

7.343 A Love-Hate Relationship: Cholesterol in Health and Disease (MIT)
In this class, we will examine cholesterol's role in the cell and in the body as a whole, from its function as a structural component of the membrane to its function in signaling. We will discuss mechanisms of cholesterol sensing, mechanisms of feedback regulation in cells, cholesterol in the brain, cholesterol in the circulation, 'good cholesterol' and 'bad cholesterol,' cholesterol-related human disorders, and the drugs that deal with some of these disorders. This course is one of many Ad

2.3 Exploring for coal

Early miners would have found it easy to trace the distinctive black colour of coal along an outcrop (for example, a coastline or river valley), and surface trenches were used to locate less obvious outcrops. However, tracing an outcrop underground was problematical as the only means of exploration was by digging costly trial shafts. The development of exploratory steam-powered drilling in the early 19th century improved matters, but it was not until the mid- to late- 20th century that more a

4.6 Accretion power

Calculations based on the above accretion disc hypothesis show that if a mass m falls into the black hole, then the amount of energy it can radiate before it finally disappears is about 0.1 mc2, or about 10% of its rest energy. Other than matter-antimatter annihilation, this is the most efficient process for converting mass into energy ever conceived. A comparable figure for the nuclear fusion of hydrogen in stars is only 0.7% of the rest energy of the four hydrogen n

Introduction

This unit provides an introduction to the evolution of mammals.

We will be considering Darwin's observations on a great many mammals, and how he noticed that species fell into natural groups. We take as an example the evolution of one particularly interesting mammal, the whale, and look at evidence both from fossils and from DNA to see which other mammals are most closely related to whales. We see how the evidence from these two very different sources points to the same relationship and

1.3.2 Peat formation in raised mires

Mires can also form inland within low-lying depressions, provided the rate of precipitation exceeds the rate of evaporation (Figure 4a). Peat is impermeable and so its accumulation progressively impedes drainage. This attribute gives mires the ability to maintain a water table independent of the area surrounding them.
