4.4 Stationary states and tunnelling in one dimension We will now use the stationary-state approach to analyse the tunnelling of particles of energy E0 through a finite square barrier of width L and height V0 when E0 < V0 (see Figure 21). 1.7 Localization of signalling proteins Since signalling proteins cannot diffuse as rapidly as small second messengers, they need be close to their downstream target in order to be able to function. Where they are located with respect to both their subcellular position and their immediate neighbours is therefore vitally important. The plasma membrane is usually the initial location, and proteins can be attached to the plasma membrane in various ways (Author(s): Subtracting Decimals - Word Problem Research methodologies for evaluating enterprise education: a tale of a study. How to Solve Geometry Proofs 5 Summary of Section 4 Put your general knowledge and geography to the test Following on from Google's spelling challenge game released Social issues and GM crops Multiplication Fact Song- (9 times tables trick) Division With Remainders Why Abenomics Matters: Abenomics and the Japanese economy [Audio] Introduction Do you want to improve your ability to subtract one number from another, especially if decimals are involved, without having to rely on a calculator? This unit will help you get to grips with subtraction and give you some practice in doing it. You can start with some practice in subtracting small numbers in your head if you want to. Then we will show you how to subtract bigger numbers on paper. Finally we look at how to subtract decimal numbers.

This video is from Sal Khan about subtracting decimals using the problem: Leo has $4,522.08 in his bank account. He deposits another $875.50 and then withdraws $300.00 in cash. How much is left in his bank account?
Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly. (02:18)

Excellent video from Jimmy Chang, who has a master's degree in math and has been a math teacher at St. Pete College for more than eight years. Mr. Chang explains what geometry proofs are and their importance.
This unit looks at the human being in the context of an individual life cycle, examining some of the processes that contribute to the formation of a new person. After a brief discussion of historical ideas about human conception, and about contraception to the present day, we look at the cells involved in the conception and development of a new individual. Gamete production (that is, production of mature cells able to unite with another in sexual reproduction) in both men and women is introduced
The genetic manipulation of plants and animals and their use in agriculture is one of the most controversial scientific developments of recent times. This free course, Social issues and GM crops, takes a look at the science behind the headlines and the complex interactions between scientific and social factors. By the end of the course it's hoped that you will have a clearer idea not only of what is possible with GM but what may be considered desirable.

Students learn how to work with remainders within a
division problem when dividing three- and four-digit numbers by a
one-digit number to obtain the correct whole number solution. They also practice the correct notation for writing a remainder in the solution.
Speaker(s): Professor Motoshige Itoh | Editor's note: The question and answer session has been removed from this podcast. Japan is highly unusual in having experienced serious deflation in recent years, and Japan’s experience may be regarded as providing a good case study for other industrial countries suffering from inadequate capital investment and what has been termed ‘secular stagnation’. This lecture explains the nature of the ‘Abenomics’ introduced by Japan’s Prime Minister, Sh

In precedent based design, solutions to problems are developed by drawing from an understanding of landmark designs. Many of the key design operations in this mode are similar to the functionalities present in case based reasoning systems: case matching, case adapting, and case representation. It is clear that a rich case base, encoding all major product types in a design domain would be the centerpiece of such an approach. EDAT (Electronic Design Assistance Tool) is intended to assist in preced
