An introduction to software development
Software development is the practice of organising the design and construction of software, the beating heart of much technology fundamental to our personal and professional life. This free introductory course, An introduction to software development, discusses the engineering nature of software development, its challenges and some fundamental practices which have developed to meet them. Software development is a fast-moving discipline and as a software development professional you must be

Stem Cell Therapies are no More Drugs Than Soufflés are Fast Food
Stemcell discoveries make great news stories, but their actual translation into routine clinical practice is still a major hurdle. Is it reasonable to expect the big pharmaceutical companies to manufacture these living therapies or is the paradigm shift from today’s drugs to ‘living cells as therapies’ overwhelming? Would McDonald’s ever put delicate soufflés on their fast-food menus? This lecture will use examples from current cell and tissue-engineered clinical therapies to illustrate

1.3 Coal-forming environments today

Coal formation begins with preservation of waterlogged plant remains to produce peat and then slow compression as the peat is buried. About 10 m of peat will compress down to form about 1 m of coal; clearly large amounts of plant debris must be available for preservation. Even so, for a significant thickness of peat to accumulate there must be a balance between the growth of plants and the decay of underlying dead material to form peat (a process known as humification).

3.3 Business operations: a transformation process

The view that operations is the set of processes responsible for producing the organisation's intended outputs from an appropriate range of resource inputs can be represented very simply, as in Figure 2.

7.2 The professional engineer

It has been suggested that there are four main criteria that identify a profession:

Custody of a clearly definable and valuable body of knowledge and understanding associated with a long period of training.

A strong unitary organization which ensures that the profession generally speaks with 'one voice'.

Clearly defined and rigorous entry standards, backed up by a requirement to register with the profession

7.1 The engineer and society

Section 2 outlined some of the needs for engineering. Society relies on engineers to create solutions to the problems involved in meeting those needs.

This is a good time to pause and point out that inevitably, in return for all this fun and power, engineers have a responsibility to society. The people who employ our services, directly or indirectly, have to have an assurance that we are working within certain social, safety and ethical boundaries. Particularly given the increasing tren

5.8.2 Removal of trace organic compounds

After conventional treatment, water may still contain trace concentrations of synthetic organic compounds, which, if left in the water, can lead to taste and odour problems. The problem is most likely to arise where the raw water source has been badly polluted. The problem can be solved by including the process of granular activated carbon adsorption after the filtration process. Activated carbon is carbon which has been activated by heating in the absence of oxygen. This resu

5.8.1 Nitrate removal

Nitrate in water has become a significant problem and the EU Directive sets a maximum admissible concentration of 50 g m−3 measured as NO3. This is equivalent to 11.3 g m−3 as N. High nitrate levels can cause cyanosis or methaemoglobinaemia in babies. Legislation allows the designation of nitrate-vulnerable zones and these help to prevent nitrate levels in natural waters increasing in affected areas.

Systems thinking and practice
What is systems thinking and practice? The essence of systems thinking and practice is in 'seeing' the world in a particular way, because how you 'see' things affects the way you approach situations or undertake specific tasks. This free course will help you to learn about the problems of defining a system and meet some of the key concepts used in systems theory: boundary, environment, positive and negative feedback, etc. Author(s): Creator not set

Internet of everything
The internet of everything (IoE) is the networked connection of people, process, data and things. As more people, data and things come online, we develop processes to harness the vast amounts of information being generated by all these connected people and things. The goal of this free course is to introduce you to fundamental concepts and technologies that enable the IoE and the internet of things. Author(s): Creator not set

1.1 Introduction

Historically, one of the most significant changes over the past hundred years has been the move away from large families living and remaining in one community to smaller family units that are required, through the economic necessity of employment opportunities, to be as mobile as possible. Extended family networks are often weaker: in many instances parents are unable to call on the support of children's grandparents, aunts and uncles, and for some people parenting can be a very isolating and
