Waste Management
How much do you think about what you throw away? A waste management cycle is essential for a sustainable future. This album considers the policy and legislation that is driving waste management processes across the EU. By modelling the overall environmental impacts of solid waste disposal methods, the UK government has now created a hierarchy of waste and local management strategies. The 12 video tracks in this album offer an in depth look at each of these processes, concentrating on waste coll

Metric spaces and continuity
This free course contains an introduction to metric spaces and continuity. The key idea is to use three particular properties of the Euclidean distance as the basis for defining what is meant by a general distance function, a metric. Section 1 introduces the idea of a metric space and shows how this concept allows us to generalise the notion of continuity. Section 2 develops the idea of sequences and convergence in metric spaces. Section 3 builds on the ideas from the first two sections to formu

Look at the shapes below. The symmetry of the shape on the left and its relationship to the shape on the right can be thought of in two ways:

• Fold the left-hand shape along the central line. Then one side lies exactly on top of the other, and gives the shape on the right.

• Imagine a mirror placed along the central dotted line. The reflection in the mirror gives the other half of the shape.

Often plans run into difficulties because of unforeseen problems or changing circumstances. For example you may be running over your deadlines, the resources or support available to you may have changed, or your personal circumstances may have changed. Plans are only a means to an end, however. If you run into difficulties, take some time to think about what effect these difficulties are having on your plans, and what changes you may need to make to your overall strategy to achieve the outcom

Tidal movements ensure that sea-shore habitats are, if not covered by seawater for part of each day, at least subject to spray-borne salt and wind. So, even well above the level of high tides, sea-shore organisms need to be more tolerant of salt than most terrestrial organisms. However, salinity (the concentration of salts dissolved in water) is not the only factor affecting sea-shore species. Seaweeds and shelled animals like limpets and barnacles are adapted to living in a highly saline mar

At this point, you might like to pause for a moment and contemplate what this phrase means to you. In particular, what do you understand by the concept of a â€˜companyâ€™?

At first, this may seem like a ludicrously straightforward questio

Whenever there is a conflict between the provisions of EU law and the provisions of the domestic (national) law of a member state, then EU law will prevail. This is a principle which was developed by the ECJ as the relationship between domestic and EU law is not clarified by treaty provisions. This is an important principle, as it ensures the proper functioning of the EU. If an EU member state had the power to annul EU law by adopting new domestic (national) law which was in conflict with the
