2.5 Surface mining

In surface mining (sometimes called 'opencast' mining in the UK), the coal seam is accessed by removing the rock overburden; a process that benefits from economies of scale by using some of the world's largest machines (Figure 15).

4.4 Reducing nutrient availability

Once nutrients are in an ecosystem, it is usually much harder and more expensive to remove them than tackle the eutrophication at source. The main methods available are:

  • precipitation (e.g. treatment with a solution of aluminium or ferrous salt to precipitate phosphates);

  • removal of nutrient-enriched sediments, for example by mud pumping; and

  • removal of biomass (e.g. harvesting of common reed) and using it for thatchi

7.340 Regenerative Medicine: from Bench to Bedside (MIT)
Regenerative medicine involves the repair and regeneration of tissues for therapeutic purposes, such as replacing bone marrow in leukemia, cartilage in osteoarthritis or cells of the heart after a heart attack. In this course, we will explore basic mechanisms of how cells differentiate into specific tissues in response to a variety of biologic signaling molecules. We will discuss the use of such factors for in vitro tissue production. We will also study the cellular mechanisms involved in the cl

1.3.1 Peat formation in deltas and coastal barrier systems

Since mires require poor drainage, low-lying land close to coastal areas might provide the right conditions for peat to form. Most extensive areas of modern peat formation are indeed situated not far above sea-level, and as Figure 2 shows, they are commonly associated with river deltas and coastal barriers. Such enviro

Terra Foundation Lectures in American Art 2019 - A Contest of Images: American Art as Culture War (4
Dr John Blakinger speaks about iconoclasm in American history and the vandalism of Confederate monuments. Iconoclasm is an enduring American value. In 1776, a mob destroyed a statue of King George III in Bowling Green, New York, establishing the new American Republic as a nation built on image destruction. More recent acts of visual violence have targeted Confederate monuments, transforming them both physically and digitally. Images of vandalism that circulate online are powerful enough to re-ca

The Hand That Signed The Paper by Dylan Thomas (read by Tom O'Bedlam)
I tried to find some sense of this poem but in the end I gave up. Dylan was about 20 years old when he wrote it. As a lyric poem it has great style. The hand that signed the paper felled a city; Five sovereign fingers taxed the breath, Doubled the globe of dead and halved a country; These five kings did a king to death. The mighty hand leads to a sloping shoulder, The finger joints are cramped with chalk; A goose's quill has put an end to murder That put an end to talk. Th

1.5 The physics and chemistry of coal formation

Coal is a type of sediment made up mainly of lithified plant remains. But how does spongy, rotting plant debris become a hard seam of coal? As discussed earlier, plant material growing in mires dies, and then rots under anoxic conditions to form peat (by the process of humification). With time, the mire becomes covered with layers of sediment, the weight of which squeezes water and gas out of the pore spaces and compacts the vegetation. As subsidence allows deposition of further mire-s
