The histone proteins
The genes for the histone proteins are very highly conserved across eukaryotes, reflecting their importance in DNA packaging. The histone family consists of five groups of proteins, histones H1, H2A, H2B, H3 and H4. An examination of their amino acid content gives us clues as to how the histones fulfil their role in DNA packaging. Rather like the polyamines in bacteria, these proteins are highly positively charged, with up to 20% of their amino acids being lysine or arginine, the charged side

Will the New Light on Wall Street's 'Dark Pools' Bring Stronger Regulation?
The latest regulatory actions on two investment banks over lapses in high-frequency trading reveal that settlements hinder the development of laws, say experts.
1.4.2 Measures of location
Everyone professes to understand what is meant by the term 'average', in that it should be representative of a group of objects. The objects may well be numbers from, say, a batch or sample of measurements, in which case the average should be a number which in some way characterises the batch as a whole. For example, the statement 'a typical adult female in Britain is 160 cm tall' would be understood by most people who heard it. Obviously not all adult females in Britain are the same

Learn French - Les Animaux, Part 4
In this video the instructor recites animal vocabulary in French. For beginning learners. The words appear at the bottom of the screen as they are recited.
1.1.3 Introduction continued
The difficulty perhaps is that things which happen at some distance from the everyday routine of our lives are often hard to place or connect with. Moreover, it has to be said that not everyone views factory sweatshops in quite the same way as groups such as Oxfam, or indeed endorses their negative claims about the use of cheap labour in places such as East Asia. For that is what the statements of such groups are: claims. And they are far from uncontroversial.
In fact, it is poss
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.

Are we now better equipped to answer the three questions posed in Section 1.1?
How are identities formed?
We present ourselves to others through everyday interactions, through the way we speak and dress, marking ourselves as the same as those with whom we share an identity and different from those with whom we do

OPSE 410: Biophotonics
An introduction to the interaction of light with biological tissues. Biophotonics for diagnostic and therapeutic applications will be discussed. Topics include propagation of light in turbid tissues, absorption, scattering, laser surgery, and optical rotation.
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
4.2 What pressures for change were exerted?
The emphasis is very much on the impetus individuals gave to change. Jim Nickson in particular seems to have been a man with energy and vision. The parents set up their own services where they were missing – a holiday chalet, swimming sessions, a club where young people could meet, above all the long-established Welfare Visitor Scheme. They campaigned for services in the community as an alternative to hospital admission. A strong theme is that work they started was often taken up by the loc
Where U.S. Politics Came From
John Green discussed where American politicians come from. In the beginning, soon after the U.S. Constitution was adopted, politics were pretty non-existent. George Washington was elected president with no opposition, everything was new and exciting, and everyone just got along. For several months, anyway. (13:57)
The Market Doesn't Solve Problems; People Do
It is wrongly accepted by many liberals (i.e., libertarians) that most, if not all, social problems can be "solved by the market." But clearly, the "market" cannot magically solve our problems. Let it be clear that there is no doubt that the best way to have social progress is to have a free market economy. However, free markets are not solutions to problems, per se, but are rather what gives us the opportunity to find our own solutions to our own problems by finding t

3.2 Surface mining
Many environmental issues arise when surface mining is considered, and such mines regularly arouse local opposition. By their very nature, surface mines have a major impact on the landscape, involving the digging of enormous pits with accompanying noise, dust and traffic movements, and destruction of mature landscape. Increasingly, in recent years the environmentally conscious public has used the planning processes to oppose and sometimes prevent mining on sites where the environmental impact
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
