8.1 Introduction The average human cell has around two metres of DNA within its nucleus. In the interphase nucleus, in which transcription and replication are going on, this DNA is packaged into nucleosomes that are variably compacted, through association with H1, into larger 30nm fibres. In fact, the average nucleus most likely contains DNA with a continuum of chromatin configurations, ranging from highly open 10Â nm fibres, through to 30Â nm fibres and fibres that are even more tightly packed together, call
7.2 Free-free radiation The blackbody spectrum is emitted when thermally emitting matter is optically thick. Optically thin matter can also emit thermal radiation. Whenever a charged particle is accelerated it emits electromagnetic radiation. When the acceleration is due to the electric field of another charged particle the emitted radiation is called free-free emission or bremsstrahlung. (Bremsstrahlung is a German word meaning ‘braking radiation’.) The radiation emitted by an optically thin, ther

Governors are not inspectors, and need to be aware of the danger that they could impinge on the role of the headteacher through inappropriate involvement in day-to-day monitoring, rather than operating at the strategic level. How monitoring is undertaken is a matter for each individual gove 1.2.1 Study Note 1 Simple rules for dealing with orders of magnitude and decimal points in decimal numbers: values ten times bigger than the order of magnitude you are looking at go to the left, ten times smaller go to the right, and less than 1 to the right of the decimal point. Note: in many European countries, a comma is used instead of a decimal point. For instance in France and Germany two and a half (in other words 2.5) can be written as 2,5.

Having read the play, do you feel that it supports or invalidates the dominant view of Marlowe as the bad boy of Elizabethan drama? There is certainly no doubt that the play has a defiant streak, that it calls into question the justice of a universe that places restrictions on human achievement and demands the eternal suffering of those who disobey its laws. On this level, it does seem to be the work of an autho Human Emotion 16.1: Physical Health I (Sleep) Pay Attention to the Penguins

This virtual manipulative is designed to teach the concept of a function by allowing you to experiment with various functions.
Observe the output of a function by dragging numbers from the top left corner to the IN chute of the function machine. The function machine will process the number and produce an output value.
-Make a guess what function the machine is using by observing the output.
-Use your guess to decide what the remaining entries of the table shoul

In this interactive resource adapted from the Wisconsin Online Resource Center, learn how a generator produces alternating current. More specifically, see how slip rings, brushes, an armature loop, and a magnetic field interact to produce single-phase alternating current. Animations show how positive and negative voltages are induced into the armature loop as it rotates through the magnetic field, and how the polarity of the voltage changes periodically, visualized as a sine wave.

This course is the second of the three parts of our graduate introduction to semantics. The others are 24.970 Introduction to Semantics and 24.954 Pragmatics in Linguistic Theory. Like the other courses, this one is not meant as an overview of the field and its current developments. Our aim is to help you to develop the ability for semantic analysis, and we think that exploring a few topics in detail together with hands-on practical work is more effective than offering a bird's-eye view of every

This course provides an introduction to important philosophical questions about the mind, specifically those that are intimately connected with contemporary psychology and neuroscience. Are our concepts innate or are they acquired by experience? And what does it even mean to call a concept 'innate'? Are 'mental images' pictures in the head? Is color in the mind or in the world? Is the mind nothing more than the brain? Can there be a science of consciousness? The course includes guest lectures by

Think of penguins as ocean sentinels, says Dee Boersma -- they're on the frontlines of sea change. Sharing stories of penguin life and culture, she suggests that we start listening to what penguins are telling us. Dee Boersma considers penguins ocean sentinels, helping us understand the effects of pollution, overfishing and climate change on the marine environment. Run time 15:09.
