Mécanismes fondamentaux en thermochimie de la biomasse (Vidéo) Dans cette vidéo, Gilles Vaïtilingom propose un cours développé par Laurent Van de Steene (CIRAD). L'objectif est d'expliquer les grands mécanismes de valorisation énergétique de la biomasse par voie thermochimique : pyrolyse, torréfaction, combustion et gazéification.
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
2.5 Cult In many ways the emperor became a figurehead who helped to bind the empire together. The emperor was promoted as larger than life, a man who bordered on the divine. It is worth noting that the text of the Res Gestae from Ankara was found attached to the walls of the temple of Rome and Augustus; it was placed in a religious centre where the emperor was worshipped. The video section on ‘The emperor in the provinces’ also examined several cult buildings which promoted the emperor's na
6.2 Working with bits You may have met the term bit, perhaps in connection with computers. The term 'bit' is also important in communication systems. It is an abbreviation for 'binary digit'. A binary digit can have just one of two values: it can be either 1 or 0. Pulses can be represented by 1s and 0s, that is, as bits, and so it is convenient to think of streams of 1s and 0s being conveyed along the communications link. The rate at which the 1s and 0s are conveyed is known as the data rate or
2.4 ‘Go Use’ science promotion events Science shops, created in the Netherlands in the 1960s and now spread throughout Europe, first emerged in the UK in 1988 (at Queen's University, Belfast). They act as a demand-driven link between a university or independent research facility and the community (usually via citizen groups, such as pressure groups, social groups, consumers and residents associations), putting one in touch with the other upon request. They carry out scientific research on practical, scientific problems at the loc
2.7 Fluorine (F) Fluoride ions (F−) are rare in foods, though some are found in tea and in seafood. However, fluoride does occur naturally in some water supplies, derived from the rocks through which the water flows. Its only role in the body appears to be to help to protect teeth from decay. The stages of tooth decay are as follows: bacteria live in saliva on teeth (form plaque) produce lactic acid → dissolves calcium salts in tooth
Fungal footbaths could save the honey bee
Globally, the honey bee population is in decline. This has serious implications for the cross pollination of commercial crops and wild plants. One of the major causes of this decline is the Varroa Destructor mite. However, researchers at Warwick University may have found a natural solution to this problem. Dr Dave Chandler from Warwick HRI explains how.
Content Marketing is About Trust, Not Just Reach
Viral videos or hashtag campaigns won’t convert customers unless they build trust and confidence with their audience.

2.4 Rapid serial visual presentation It has been known for a long time that backward masking can act in one of two ways: integration and interruption (Turvey, 1973). When the SOA between target and mask is very short, integration occurs; that is, the two items are perceived as one, with the result that the target is difficult to report, just as when one word is written over another. Of more interest is masking by interruption, which is the type we have been considering in the previous section. It occurs at longer S
Woolly rhinos, breeding salmon, weighing oceans
This week: how woolly rhinos could bring insights into ancient climates, why breeding salmon is helping conservation and a device that can weigh the oceans.
4.3 Physical grounds for thinking we are immortal In section III Hume discusses what he calls physical reasons for thinking there is an afterlife. A sensible guess as to what he means by a physical reason is that it is one based on observation and experience of the physical world. He begins by asserting that physical reasons are the ones he has most respect for. (This assertion is unsurprising: his objections to moral reasons, and the metaphysical reasons we skipped, turn on the allegation that they depend on claims that go beyond wha
Understanding depression and anxiety
This free course, Understanding depression and anxiety, explores the causes of these mental health issues, with a particular focus on stress. You will consider some risk and causal factors for some depression and anxiety disorders, and learn about the biology and psychology behind them. First published on Mon, 14 Sep 2015 as Author(s):

2 Creationism in disguise In recent years, creationists have re-branded their hypothesis as 'intelligent design', which asserts that the apparently designed fit of organisms to their conditions of life necessarily implies the existence of an intelligent designer. This idea is no more than the old 'argument from design', promulgated most famously by William Paley in his fable of chancing upon a watch and inferring a watchmaker, which the theory of evolution by natural selection refutes, as brilliantly explained by Rich
6.4.1 Implications What does this all imply for decision making? First, the importance of control perceptions to decision makers' perceptions of risk suggests an important source of bias. In a study of managers' risk taking, Zur Shapira (1995) found that managers would often discount risks on the basis that they felt they could control them. In my own research on traders' decision making, I found traders to suffer from control illusions and their risk judgement and performance to suffer in consequence: illusory
