TALAT Lecture 1201: Introduction to Aluminium as an Engineering Material
This lecture provides an introduction to metallurgical concepts necessary to understand how structural features of aluminium alloys are influenced by alloy composition, processing and heat treatment, and the basic affects of these parameters on the mechanical properties, and hence engineering applications, of the alloys. It is assumed that the reader has some elementary knowledge of physics, chemistry and mathematics.

3.1 Arithmetic with whole numbers When you are adding or subtracting whole numbers, an important thing to keep in mind is the place value of the figures. It is often a good idea to set out the numbers in columns before doing the arithmetic. (a) There are 4 Let them eat cake!

But where are these instructions stored within the computer? The answer is that they are stored within what is called the computer's main memory, along with any data needed to carry them out. However, the main memory in computers like PCs is much too smal Keep on learning   There are more than 800 courses on OpenLearn for you to c 2.10 Selenium (Se) Selenium is found in the body in an important group of enzymes (glutathione peroxidases) which have important antioxidant properties and work in conjunction with vitamins C and E to destroy free radicals in cells. Some studies have shown that a higher selenium level is linked to a lower risk of breast, prostate and colon cancer, which may in part be due to selenium's antioxidant function. Other selenium-containing proteins help to regulate thyroid function and play a role in the immune system Acknowledgements The content acknowledged below is Proprietary (see terms and conditions) and is used under licence.This content is made available under a Creative Commons Attribution-NonCommercial-ShareAlike 2.0 Licence Grateful acknowledgement is made to the following sources for permission Tafels oefenen : Bingo Met dit bingospel kunnen leerlingen de tafels inoefenen.

They use colors to show different countries, provinces, or states. Colors are used to show different elevations on relief or physical maps, different vegetation, climate, or distribution of population. Video gives examples of each type of map and explains how to use them. Good video for beginning map readers. (02:31) Remote Village Where People Walk on All Fours | 60 Minutes Australia

A founder of multiple companies himself, von Windheim was already teaching entrepreneurship courses at Duke when he recently joined the Nicholas faculty to lead the new environmental entrepreneurship certificate program. Classes in the two-year program will train students to understand business models and
What strategies can hospitals adopt to reduce their impact on the local and global environment? How might they reduce the carbon footprint of vehicles transporting patients, visitors and goods? This album visits three hospitals which have adopted green approaches to energy efficiency, by cutting electricity consumption, reducing traffic volume, and even generating their own renewable energy. This material forms part of The Open University course T206 Energy for a sustainable future.Author(s):

In this video students learn the definitions of a trapezoid, an isosceles trapezoid, and the median of a trapezoid. Students also learn the following theorems related to trapezoids. The base angles of an isosceles trapezoid are congruent. The median of a trapezoid is (a) parallel to the bases and (b) has a length equal to the average of the lengths of the bases.
