Air Pollution
How we can be sure our air is safe to breathe? This album introduces the principles and concepts of air quality management and looks at how we analyse pollution control problems. Five video tracks review the nature and characteristics of air pollution today and demonstrate how air quality data is interpreted. They include a comparison between shipping and car emission levels, the processes used to remove pollutants from the air, and ways in which British Aerospace could limit its Volatile Organ
Introduction to finite element analysis
What is finite element analysis (what is it and why do we carry it out? This free course, Introduction to finite element analysis, introduces the essence of finite element analysis. As an example of its use, you will look at the case of FEA of the tub of a racing car. You will also have the opportunity to try out two exercises to carry out a simple analysis of a plate and a square beam.

Technology Evaluation
The aim of this free course, Technology Evaluation, is to provide you with the knowledge you need to develop and work with forms of evaluation that take full account of the contextual, conceptual and theoretical factors that underpin, inform and shape the evaluation and assessment of technology and technology-intensive projects and programmes.

Figure 16 shows two rates with different activation energies of 1.0 and 0.5 eV – which curve is which? 3.2 Sub-state forms of nationalism The advancement of democracy in contemporary Western nation-states and the intensification of globalisation processes have encouraged the re-emergence of nationalist movements representing oppressed or silenced nations that demand the right to self-determination. In the case of ethnic groups formed by people of immigrant origin, democracy has provided them with the tools to pursue the right to develop and practice their indigenous culture and language alongside those of the host country. One 4.5 Conclusions There are many different types of projects; all have specific objectives, constraints (such as budgets and schedules) and a group or team responsible for the completion of the project. Project teams are effective when both task and relationship behaviours are competently handled. The main task-oriented behaviours are: estimating and planning; assembling a team; reporting a 2.3.5 Mixed structures Teams often have mixed structures: some members may be employed to work full time on the project and be fully responsible to the project manager. Project managers themselves are usually employed full time. others may work part time, and be responsible to the project manager only during their time on the project. For example, internal staff may well work on several projects at the same time.

Dan can no longer bear Ned's rather dark and erratic behaviour, and he grabs the conversation by suddenly pouring out all the overwhelmingly negative aspects of his life as a dentist, father and lover. Some people might say that ethics is about how to live a ‘good’ life and, clearly, Dan needs a change. He recognises he is not leading a ‘good’ life. He knows all the things that are 4.7 The story so far This section looked at the play Last Call. The play is very rich in ethical issues, and one of the most interesting points that are made is that, whilst there are many ‘big’ ethical questions worthy of discussion and investigation, it seems to be in the everyday, routine conversations and dealings of people that ethical questions get to be asked and answered, even if this is not clearly recognised. A major ethical issue tackled in the play is loyalty: giving preference in som 1.7 Ideology The notions of a final vocabulary and that of ideology are closely related. Anthony Giddens defined ideology as ‘shared ideas or beliefs which serve to justify the interests of dominant groups’ (Giddens, 2006, p. 1020). There are all sorts of problems with this definition. One difficulty, for example, is that ideas and beliefs, if they have any kind of existence, are hidden away and have to be inferred by what people do and say. Another difficulty surrounds exactly how these things can be Acknowledgements Except for third party materials and otherwise stated (see terms and conditions), this content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 Licence Grateful acknowledgement is made to the following sources for permission to reproduce materia Introduction This unit focuses on the Forth Road Bridge that connects Edinburgh with Fife. This suspension bridge continues to face a number of problems regarding its deteriorating condition. The short video included in this unit illustrates some of the major structural issues facing bridges and examines some of the proposed changes to the use of the Forth Road Bridge to help increase its lifespan. Learning outcomes After studying this course, you should be able to: Explain correctly the meaning of the emboldened terms in the main text and use them correctly in context Identify whether a given sound source can be classed as a musical instrument and explain why (Activity 2) Identify the primary vibrator and any secondary vibrators in the most common types of instrument (Activity 3) Appreciate that, when a note is played, a musical in References Keep on learning   There are more than 800 courses on OpenLearn for you to Conclusion This free course provided an introduction to studying Technology. It took you through a series of exercises designed to develop your approach to study and learning at a distance, and helped to improve your confidence as an independent learner. 6.4 Summary After passing through a treatment works, water flows via transmission mains to service reservoirs which act to even out variations in consumption during a 24-hour demand period. It is then taken by distribution mains from the service reservoirs to the consumers. The head of water necessary for flow is provided by positioning the service reservoir at the correct level or by pumping. A pumped pipeline is called a rising main. The size of mains pipelines depends on the quantity and flow rate of 5.15 Summary The basic water treatment process for surface waters consists of preliminary screening and storage, followed by coagulation and flocculation to allow the aggregation of colloidal particles. Sedimentation of the aggregated particles produces sludge and partially purified water. The purification process is completed by filtering and disinfecting the water before distribution. Some waters may require additional treatment: for example, nitrate removal, or fluoridation, or further removal of organ
