Clemson awards first female in the nation Ph.D. in automotive engineering
CLEMSON — A Clemson University student is about to make national history as the first woman in the country to earn a Ph.D. in automotive engineering. Ala Qattawi is among nearly 200 students in Clemson's automotive engineering program who are pursuing graduate degrees in the male-dominated field. Qattawi's work involves concept cars and establishing a scientific approach for the design of structural origami in folded sheet metal. She said the technology will improve automobile efficiency and

2.5 Intracellular receptors

Signal receptors are usually located at the cell surface. However, it is important to remember that there are some groups of receptors that do not fit into the general signal transduction model set out in Figure 2, These are intracellular receptors, which bind small or lipophilic molecules such as steroid hormones, which can cross the cell membrane. The signalling pathways activated by these receptors seem quite simple compared with the other pathways we shall be dealing with, but the same pr

2.2 Receptor specificity

Binding of an extracellular signal to its receptor involves the same type of interactions as those between an enzyme and its substrate. Receptor specificity depends on the binding affinity between the ligand and the binding site on the receptor. The dissociation constant (KD) describes the affinity between receptors and their ligands.

Proteins can be thought of as consisting of various domains, and the different combinations of structural motifs in the extracellular re

2.2.1 Using a calculator for scientific notation

You are likely to be doing many calculations with numbers in scientific notation, so it is important that you know how to input them on your calculator efficiently and how to interpret the results.

First, make sure that you can input numbers in scientific notation on your calculator. There are a couple of ways to do this, but the most straightforward is to use the special button provided for entering scientific notation. This might be labelled as EXP, EE, E or EX, but there is considera

2.2 Going up: using scientific notation for large numbers

Think again about the value for the total volume of water stored on Earth: 1460 000 000 km3.

When dealing with large numbers such as one thousand four hundred and sixty million (1460 000 000), it is tedious to write the number in words or to keep writing all of those zeros. Worse still, it is very easy to lose some of the zeros or add extra ones by mistake. Fortunately, large numbers can be referred to without having to write out all of the zeros. The powers of ten not

2.1 Where water occurs and how we measure it

When astronauts first ventured to the Moon in the late 1960s, they were captivated by a vision of the Earth in colour as it had never been seen before (Figure 2). It is not surprising that, after pictures like this were published, the Earth became known as the ‘blue planet’.

1 The power of water

The ways in which human activities interact with the water cycle can have devastating consequences for all forms of life. These range from the very large scale – for example, the effects of the movement of large volumes of water in a tsunami – to the molecular scale and the ability of water to dissolve solids, such as agricultural fertilisers (Figure 1).

Learning outcomes

By the end of this unit you should be able to:

  • read data presented in tables;

  • use scientific notation to express both large and small quantities;

  • appreciate why chemists use different models to represent molecules;

  • identify the number and type(s) of atom present in a molecule from its chemical formula;

  • identify the reactants and products of a reaction in a chemical equation;

  • read and write using chemical

8.1 Iodine (I)

Iodide ions (I) derived, like all mineral elements, from the breakdown of rocks, is present in some soils, but much of it has been dissolved out by water over millions of years and washed down into the sea. It is concentrated by some marine organisms, and so can occur at quite high concentrations in edible seaweed, and in fish and other seafood. Thus people living near coasts often have sufficient iodine in their diet, whereas those living in mountainous areas, such as the Himal

Double affine Hecke algebras (DAHA), also called Cherednik algebras, and their representations appear in many contexts: integrable systems (Calogero-Moser and Ruijsenaars models), algebraic geometry (Hilbert schemes), orthogonal polynomials, Lie theory, quantum groups, etc. In this course we will review the basic theory of DAHA and their representations, emphasizing their connections with other subjects and open problems.

8.251 String Theory for Undergraduates (MIT)
This course introduces string theory to undergraduate and is based upon Prof. Zwiebach's textbook entitled A First Course in String Theory. Since string theory is quantum mechanics of a relativistic string, the foundations of the subject can be explained to students exposed to both special relativity and basic quantum mechanics. This course develops the aspects of string theory and makes it accessible to students familiar with basic electromagnetism and statistical mechanics.
