5.5 Vibrating string: pitches of notes produced by stringed instruments When a string is bowed, plucked or struck, energy is supplied that starts the string vibrating. The string doesn't just vibrate in one single mode; instead, it vibrates in a combination of several modes simultaneously. The displacement along the string is the superposition of the standing-wave patterns corresponding to those modes. For example, if the string vibrated only in the first and second modes, the displacement at a given instant of time might appear as shown in Author(s):

This is rather like the distinction made between the content and context reading of photographs. Once you are sure that you know what the main heading means, focus on a particular element and think it through. If it is a bar chart, for instance, pick on one of the bars and tell yourself what it represents, what it is telling you. Is it showing a percentage or a total?

Perhaps the best way to answer that is to write another version of the essay, building on all the things we have discussed. In fact, I have taken the basic content of Hansa's essay, tidied it up and shuffled it about a little to bring out her argument more strongly. (However this is not the only possible way of structuring an argument in answer to this question.) I have also woven in some of Ellis's terms, 4 Aerobic fitness training methods Various training methods can be employed to develop aerobic fitness. In the activity below we explore some examples used by a team of footballers. Watch th 4.1 Introduction Pusztai and his team were attempting to develop suitable tests to assess the safety of GM potatoes. Typically, testing the safety of GM food involves comparing its composition and/or its effects with that of the conventionally produced food it most closely resembles. We have seen that such comparisons were at the heart of Pusztai's work. The comparison of GM and conventional crops and food has led to the so-called principle of substantial equivalence, which has been used extensiv 7.1 Processing meanings Reading and thinking requires you to begin to process the material you read in preparation for re-presenting it in assessments. Initially, processing happens in your head. Selecting what to identify and extract will start the process off. Summarizing the arguments continues this process and, crucially, gets you started on reproducing ideas in your own words. The next stage is to develop your notes further by thinking more consciously about the material you have read and the points you Modelling pollution Energy policy and climate change 9.1.1 Point of view Decide first of all which user's point of view you are taking: consumer, operator, maintenance person, and so on. You may want to make several trips, from different user perspectives, or try special user perspectives, such as that of a disabled person. It is usually easiest to take a consumer's trip because you may need special permission, access, and perhaps skills, before you can take any other.

As the BRICs falter, a new group of growth economies is emerging, but they have lots of work to do before they are stable enough to become serious players.

The cleaning up of the North American Great Lakes is one of the great success stories in pollution control. Modelling gives scientists the tools to forecast outcomes in a complex environment: how will the pollution accumulate? what will happen if pollution is stopped all together? The two video tracks on this album demonstrate how modelling techniques provide a scientific basis for the political decisions that have revived the area. The material forms part of course MSXR209 Mathematical Modellin
The 2009 United Nations Climate Change Conference in Copenhagen presents a new focus for international debate and decisions about energy and its use. What are the countries of Western Europe and Scandinavia doing to promote sustainable energy production? Just how different will the future energy map of Europe look? And is energy policy principally a scientific issue or a political one? This album contains a series of films exploring energy policy in various countries around Europe in 2006, frame

About St. Petersburg College:
In 1927, St. Petersburg College (then known as St. Petersburg Junior College) became Florida's first private, non-profit, two-year school of higher learning located in downtown St. Petersburg. Full accreditation followed in 1931 and in 1948 SPC became a public college.
In June 2001, SPJC officially became St. Petersburg College when Flo

This album Investigates recent debates in sociology, cultural theory and psychoanalysis, and explores the nature of social identity, ‘socialisation’, subjectivity and personhood. The case studies explore the value and relevance of different theoretical frameworks for understanding identity by applying the main concepts in real situations. The material is taken from The Open University course D853 Identity in question.Author(s):

This letter from the Bell family expresses the gratitude they felt towards the caregivers at the University of Maryland Marlene and Stewart Greenebaum Cancer Center who treated their father, Robert Bell. Though they were heartbroken at his passing, the memories of the loving care he received helped them through their difficult time.
