1.7.1 Carboniferous mires

During the late Carboniferous, mires developed over vast areas of the UK. Much of today's land area was an extensive, low-lying plain bordering a sea to the south (a sea that was soon to be the site of a mountain-building episode). Any mountains that existed lay hundreds of kilometres to the north. Large river systems meandered southwards across these plains.

At that time, the UK lay in tropical latitudes, almost on the Equator (see Author(s): The Open University

1 Geothermal energy

Although energy from the Earth's interior that flows though the surface is on average very low — about a thousand times less than the solar energy that falls on the surface — it is sufficiently abundant worldwide to make it locally worth exploiting. The top 3 km of the Earth's crust stores an estimated 4.3 × 107 EJ of thermal energy by virtue of the temperature of rocks and their thermal capacity. Because global consumption of energy during 2002 was 451 EJ heat stored within t

7.1 Introduction

So far we have presented two pieces of evidence pointing to the occurrence of a big bang: the redshift of the galaxies (indicating the continuing expansion of the Universe), and the 3 K radiation (the remnant of the primordial radiation). But there is a third imprint such a big bang ought to have left on our present-day world. We cannot at this juncture trace out the full sequence of events following the instant of the big bang (that can only be done after we have worked through the next two

2.4 Modern mine planning

Once the geological data gathered during the exploration phase has been evaluated, geologists will estimate the quality and quantity of coal present. Coal reserves (in tonnes) are calculated from volume × density (Section 5). The volume of coal is controlled by seam area and seam thickness.

Hence:

tonnage = seam area × se

Office 365 Goes to the Movies

Think of how movies would be different if they'd only had Office 365. How can mobsters keep tabs on enemy families? Presence in Lync. How can the beleaguered sheriff keep law and order in the Old West? Shared Outlook calendars. See how in The Office Show Classic Film Festival! They don't make movies like these anymore.

7.341 Brightening up Life: Harnessing the Power of Fluorescence Imaging to Observe Biology in Action
One summer in the 1960s a young Japanese researcher, with the help of a few high school students, chopped up ten thousand jellyfish. As a by-product of this harvest, they isolated a green fluorescent protein (GFP). Since then, GFP has triggered a revolution in our understanding of gene expression and signaling in live cells. In this seminar, we will examine how this small protein generates fluorescence, i.e. absorbs light of one wavelength and emits light of a longer wavelength. We will discuss
