3.5 Journals

Journals and articles written by academics or experts are an excellent source of information. Journals are usually published monthly or quarterly, and contain a selection of articles providing details of recent research. Often they will also contain reviews of relevant books. They are usually published more quickly than books, and so are often more up to date.

To access content of journals, most publishers require a subscription. There are, however, some journals which you can freely ac

Babbage: The element-hunters

It is 150 years since Dmitri Mendeleev discovered the periodic table, the innate order underpinning the elements. Kenneth Cukier explores how this simple grid has shaped our understanding of the universe and our place in it. In a laboratory near Moscow the search is on for element 119, but on the other side of the world in California, researchers are hesitant. Is chemistry over?

1.1 Why does it hurt?

The relief or avoidance of pain must be one of the major driving forces behind medical research. In this course we start the discussion about relief of pain.

When we experience the sensation of pain it is likely that something is happening that the brain needs to know about, so it can direct us to whatever damage-limiting action is needed. We hurt because we have genes that constructed a body able to feel pain.

Without such a mechanism it is likely that life would be much shorter,

3.1 Who will make the decisions?

Where will the decisions be made that will result in meaningful action on climate change, and who will make them stick? Following climate change politics in the media can give the impression that most of the action on climate change is going on between national decision makers in international forums. It is important to keep in mind that these forums have resulted from persistent pressure from a combination of grassroots environmental activists and a global network of science and policy exper

Lecture 7: Engineers at War
Lieutenant Colonel (Retd) Christopher Pugsley on "Engineers at War". Many of the most prominent man-made historical features in the landscape are the work of military engineers. Hadrian's Wall, Windsor Castle, the coastal fortifications, even the Albert Hall, all testify to the skills of the military engineer. Military engineers throughout history have always had to marry theory and genius to the practical skills of making the concept work in crisis on the ground; no small accomplishment.

Electronics in Chemistry: Building Spectrophotometers
“One of the most useful skills you could have as a chemist is to know electronics,” says Professor of Chemistry Amy Witter, whose new analytical chemistry class, Destroy Build Destroy, has students building their own spectrophotometers. A spectrophotometer is a device used to measure light, allowing chemists to determine the concentration of chemicals in solution. (01:22)

The Quest for the Structure of the Ribosome: A Personal Voyage
The 2019 Haldane Lecture was delivered by Sir Venki Ramakrishnan, President of the Royal Society, on February 7th at Wolfson College, Oxford. The lecture was introduced by College President Sir Tim Hitchens. The thousands of genes in our DNA are translated by ribosomes - ancient, enormous molecular machines that read the genetic code to make the thousands of proteins that carry out the functions of life. Although the ribosome was discovered in the 1950s, unravelling its million atom structure to

6 Summary

This course has looked at specifying the requirements of a job by drawing up a job description and a person specification. We considered how you might indicate the qualities required of individuals in relation to person-organisation fit as well as the more traditional approach of person-job fit. We then considered various methods of attracting candidates and the process of arriving at a shortlist. We have stressed the importance of preparing for the selection process, be it an interview alone

Session 3: Getting students to chose a viable blogging subject/topic

Purpose/Aim of this session 

In this session you will be introduced to ways you can support students in finding a topic to blog about, which is referred to as a niche. Niche blogging is important for:  establishing one’s self as an expert in a given field, building an online community, discoverability online and attracting a loyal following.

Geoff Baylis Lecture 2009
The Geoff Baylis lectures are a joint initiative between the Otago Botanical Society and the Department of Botany, University of Otago. This lecture was presented by Associate Professor Daphne Lee, a paleo-botanist. The title is "Palms, Podocarps, orchids and proteads: the contribution of new fossil plants from Otago and Southland to our understanding of NZ's vegetation history." The lecture was given on the 16th of September 2009.

1.10 Changing sea-level

Sedimentary rocks reveal how environmental conditions in Britain's geological past were extremely different from those of the present day (in fact ‘Britain’, like the rest of the Earth's geography is transitory when viewed in terms of the very long span of geological time). As well as evidence from sedimentary rocks, recent landforms also indicate that in the more recent geological past (within the Quaternary Period), sea-level was not the same as it is at present.

2.1 Chemical periodicity

The chemistry of the elements is immensely varied. But amidst that variety there are patterns, and the best known and most useful is chemical periodicity: if the elements are laid out in order of atomic number, similar elements occur at regular intervals.

The discovery of chemical periodicity is particularly associated with the nineteenth-century Russian chemist Dmitri Ivanovich Mendeléev (Figure 16). The periodicity is represented graphically by Periodic Tables. Author(s): The Open University

2.2.1 Positive integers: denary numbers

The number system which we all use in everyday life is called the denary representation, or sometimes the decimal representation, of numbers. In this system, the ten digits 0 to 9 are used, either singly or in ordered groups. The important point for you to grasp is that when the digits are used in ordered groups, each digit is understood to have a weighting. For example, consider the denary number 549. Here 5 has the weighting of hundreds, 4 has the weighting of tens and

5.13 The final Act

In Act 3, Dan and Ned are back in Ned's flat and Ned is showing extreme signs of neurosis and paranoia. 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

7.1 Introduction

You will already be aware of some of the many experimental techniques employed to study protein structure, including X-ray diffraction, CD, NMR and SDS–PAGE. There are also many techniques that have been developed to study protein function, of which several are described in this section.
