RVC 25 - The Role of Mitochondria in Health and Disease
Mitochondria are cell organelles which play a critical role in energy supply in most higher organisms. But how did that role develop and how do they achieve this function? In the latest episode of the RVC Podcast Dr Michelangelo Campanella discusses these questions and relates his research findings on how poor mitochondrial function can contribute greatly to disease processes.

3.1 Patches and antivirus software

In this section we will look at two of the ways in which you can protect yourself from malware:

  1. Ensure that your computer has the latest patch from Microsoft or your operating system vendor.

  2. Install antivirus software that will protect you from these problems, and ensure that you keep it up to date.

(Later in this course we will discuss firewalls, which you can also use to protect your computer.)

8.5 Looking for Hinduism in Calcutta

2.5 From phoneme to sentence structure: the syntactic problem

In the vervet monkey system, calls stand by themselves. Thus there is no syntax. Syntax can be thought of as working like road traffic rules do. It doesn't much matter which side of the road you drive on, as long as there is some clear convention. Similarly in (13), it is necessary to understand the difference between (13a) and (13b) without ambiguity, by having some rule or other about which noun phrase comes first. England may differ from most of the rest of the world in terms of the side o

4.2 The effects of irrelevant speech

Imagine watching a computer screen, on which a series of digits is flashed, at a nice easy rate of one per second. After six items you have to report what the digits had been, in the order presented (this is called serial recall). Not a very difficult task, you might think, but what if someone were talking nearby? It turns out that, even when participants are instructed to ignore the speech completely, their recall performance drops by at least 30 per cent (Jones, 1999).

1.1 Thoughts on a PhD

Entering students often think of a PhD as a ‘magnum opus’, a brilliant research project culminating in a great work. This is rather a demanding model, and few students win Nobel Prizes as a result of their doctoral studies. More realistically, a PhD is research training leading to a research qualification. The PhD is a passport to a research career.

There are other views of a PhD, as well. Getting a PhD can be a ‘rite of passage’, prerequisite to admission into the academic ‘t

5.4 Unified models

You are now familiar with the main components for building models of AGNs: a central engine powered by an accreting supermassive black hole (with or without jets), clouds of dust, clouds of gas and accretion processes that can organise the gas and dust into a torus-shaped structure. Many attempts have been made to use these components to explain the different types of AGN. Two basic ideas - or perhaps hopes - underlie these models.

First, all AGNs are essentially the same and differ chi

7.340 Immune Evasion: How Sneaky Pathogens Avoid Host Surveillance (MIT)
Every infection consists of a battle between the invading pathogen and the resisting host. To be successful, a pathogen must escape the many defenses of the host immune system until it can replicate and spread to another host. A pathogen must prevent one of three stages of immune function: detection, activation, or effector function. Examples of disease-specific immune evasion and the mechanisms used by pathogens to prevail over their hosts' immune systems are discussed. Also considered is what

1.9.2 To sum up

Such an analysis reinforces the notion of discourse as a form of work or labour. It also implies a strategic speaker. But, again, is this the case? Are speakers strategic in this way or just doing what comes naturally? It can suggest, too, a duplicity in Diana's actions. Potter is not implying this, however. Rather, as knowledgeable speakers and competent members of discursive communities, we are all, like Diana, skilled in a range of methods for accomplishing different activities such as sta

4.2 Index

It is not practical for the search engine to go looking at every page on the Web whenever it receives a search request. Instead, the search engine consults a vast index to the Web. This index is prepared in advance and is stored as a database to make retrieval as efficient as possible. The index of a search site is just like the index of a book – it contains a list of words, each with a reference to the page on which that word was found. The reference to the original page is, of course, a U

8.1 Overview

Following the Scottish Parliament elections in May 2007, the balance of power and system of government in Scotland has changed significantly, giving rise to Scotland's first minority government, led by the Scottish National Party.

The first three units in this section consider issues of nationalism, political devolution and the role of nation-regions in the European Union. The final two units consider social issues such as geographical identity and poverty in Scotland.

2.3 Truth values

We will want to distinguish between statements that are true and statements that are false. Another fundamental form of data allows us to do this. This form of data consists of just two values, which we shall write as true and false.

Not all texts use the same notation: some use T and F; others may use 0 for false and 1 for true (or the reverse!).

We may refer to true and false as truth values, or Boolean values
