2.5 Obesity and ageing So, it seems that a part of the explanation for Ron's obesity, and the health problems that have led him to seek medical advice, may relate to the environment in which he is living, and more specifically the diet that he has chosen. It may also be a diet that is especially effective in activating the reward circuits in Ron's brain. However, Ron is also in his later middle age. A longitudinal study of people of this age in the USA suggests that average body weight increases by 1–2 kg per dec
3.2 The evolution of the EU The EU has grown out of a series of intergovernmental political initiatives which have been expressed in a number of treaties. These treaties form the building blocks that give authority and power to the institutions and law-making bodies of the EU. The process is evolutionary, as treaties are reviewed and amended to reflect both the changing membership and the vision of the EU. The EU is founded on several treaties: The treaty that established t
Food Scientists Make Smoother Ice Cream
Food chemists add a tasteless edible protein called gelatin hydrolysate to ice cream find that it keeps ice crystals small, resulting in a smoother, more pleasing product. The protein inhibits the growth of ice crystals, keeping them small and preserving the creamy texture of ice cream. (1:33)
7.2 Coding of information in the higher auditory centres We have seen that in the cochlear nerve, information about sound intensity is coded for in two ways: the firing rates of neurons and the number of neurons active. These two mechanisms of coding signal intensity are found throughout the auditory pathway and are believed to be the neural correlates of perceived loudness. The tonotopic organisation of the auditory nerve is also preserved throughout the auditory pathway; there are tonotopic maps within each of the auditory nerve relay nuclei, the
Let's Improvise Together
The creators of ?Let's-Improvise-Together? adhere to the idea that while there is a multitude of online games now available in cyberspace, it appears that relatively few are focused on providing a positive, friendly and productive experience for the user. Producing this kind of experience is one the goals of our Amusement Project.To this end, the creation of ?Let's Improvise Together? has been guided by dedication to the importance of three themes:* the importance of cooperation,* the importance
4.13.3 Scrutiny Again, connected to the accountability issue is the problem of adequate scrutiny. The detailed, technical and specific nature of much-delegated legislation means that, on the whole, Members of Parliament (the elected representatives) do not have the expertise to consider proposed legislation effectively. In addition, you have already noted that the scrutiny committees themselves only have limited powers.
3.4 Specialisation within language areas: brain scanning Is there any evidence from the undamaged brain that the view derived from aphasia is indeed correct? The most useful methodologies here use either PET or functional MRI (fMRI) scanning to establish which parts of the brain are active in particular tasks. The difficulty is that a standard linguistic task, such as understanding a sentence's meaning, involves phonology and syntax and semantics, and thus is not helpful when trying to tease out which of these subtasks happens in which areas.
Radio Lingua Network News: 26 September 2008
Happy European Day of Languages to all our listeners! By way of joining in this international celebration of languages and language-learning we're delighted to introduce eight new podcasts today. We're adding Catalan, Danish, French, Japanese, Mandarin and Romanian to our One Minute Languages series; we're introducing our first podcast for English learners - Write Back Soon will help learners master Phrasal Verbs; and we're finally announcing the long-awaited sequel to Coffee Break Spanish: it's
2.1 Introduction The unique climate and topography of each desert links to the unique and characteristic flora and fauna found there. From the brief description of deserts provided in Section 1, you can appreciate that a desert provides a variety of niches for animals and plants. The term ‘niche’ applied to animals describes its role in a particular environment, and includes a number of characteristics such as habitat range, how the animal feeds, its diet, its environmental requirements and also its preda

5.14 Response and damping You have learned so far in this chapter that when a musician plays an instrument, they force the primary vibrator to vibrate. If the primary vibrator is driven at one of its resonance frequencies, the normal mode of vibration corresponding to that resonance frequency will be excited. Now, in practice it is also true to say that even if the primary vibrator is driven at a frequency close to the resonance frequency, the normal mode will still be excited, but just to a lesser degree. In other wo
8.1 Genes and behaviour In the preceding sections many different proteins have been mentioned. These proteins are the receptors, signals, channels, enzymes, transporters, structural components and transcription factors that enable the nervous system to grow and function. Other proteins (e.g. the actin in muscles) are involved in making limbs move and sense organs function. Any and all behaviour is dependent on these proteins. And as each of these myriad proteins is the product of a gene, it follows that any and all

Open education
There are many different 'flavours' or interpretations of what openness means in education. This free course, Open education, is an example of a massive open online course (MOOC) and spans seven weeks. Like all the free materials on OpenLearn, this course is open to the wider world but, uniquely, it also forms part of the module for students who are studying the Open University course H817, 'Openness and innovation in elearning'.Author(s):
1.4 Video follow-up Did the programme add to your factual knowledge? You might like to pursue the question of whether Sunday should be preserved on religious grounds or as a day of common rest for purely social and recreational reasons, or whether provision should be made both to preserve Sunday as a Christian day of worship and to allow members of other faiths rights to take time off work or school on other days of the week to perform worship and to celebrate their own festivals. You might want to test your res
References Introduction This unit explores the topic of climate change and global warming. We will begin by exploring how the Earth’s global mean surface temperature is determined through a global “balancing act” of the rate of energy that comes from the Sun and the rate at which the planet returns that energy into space. We will also discuss the natural greenhouse effect, and how this contributes to a balanced global climate. We will then go on to consider the human impact on the atmosphere, including the imp 5.7 Vibrating air column: reflection at the end of an air column When a sound wave reaches the end of an air column, it is clear that it will be reflected if the tube end is closed. You only have to imagine yourself standing some distance, let's say 50 metres, away from a flat wall. If you shout, you will hear an echo – the reflection of the sound wave you projected. There is one difference, though, between the reflection of a sound wave and the reflection of the wave on a string that you met previously. When a sound wave is reflected from a closed SIFUD-PP Paris 2016 : Utiliser un renforcement prothétique après 80 ans est-il raisonnable ? ...

2016 08h50 OUVERTURE : ... Duel: To Rent or Buy a Home?
Owning a home is a huge part of the American Dream. But is the dream of homeownership really all it’s cracked up to be?
In this new Econ Duel from Marginal Revolution University, Professors Tyler Cowen and Alex Tabarrok weigh in on the issue. Each representing a side of the home ownership debate, the two professors ask what’s smarter—to rent, or to buy?
On the “buy” side, Tyler Cowen shares the tax advantages of buying a home as well
