The Eerie Glow of the Antarctic Aurora Illuminates the Continent, Seen from Space

Magnetic fields pierce the surface, barely constraining the dozens of millions of tons of ionized plasma that flow along them. These loops of magnetic force store vast amounts of energy, and if released, can explode with the force of millions of nuclear bombs. And when they do, that matter is hurled into space at speeds hundreds of even thousands of times faster than a rifle bullet.

Screaming across the solar system, most of that material misses the Earth, such a small target we are. But sometimes the geometry is right, and that debris bears down on us.

At a Glance Overview Students apply their growing understanding of the concepts of toxicology (dose, response, individual susceptibility, potency, and threshold) to their discussion of the 1950s tragedy in Minamata, Japan.

Chemicals - Manual - Lesson 5

They learn how to assess the risk of people to specific chemical hazards and make decisions about how to manage that risk. Major Concepts People can make some choices about chemical exposure; however, some exposure is controlled at a level other than an individual one. Objectives After completing this lesson, students will Background Information The Minamata Case Study When people living in Minamata, Japan, in the 1950s began slurring their speech occasionally or dropping their chopsticks at a meal, no one thought much of it.

We now know the tragic story of Minamata. The consequences of such blatant polluting seem obvious to people today. Risk Assessment How a person is exposed to a chemical also determines the factor of risk. Chemistry.

Get better grades, increase your knowledge, make your work easier, enjoy learning. Basic Oxygen Steelmaking. In this simulation you will play the role of plant metallurgist in charge of the BOF operations.

Basic Oxygen Steelmaking

You will have to decide on scrap and addition materials, and the amount of hot metal to charge into the BOF to attain a target composition of the chosen steel grade and to tap within required time and temperature limits. You should also aim to minimize the cost of the whole operation. This completes the current section. If necessary, please ensure that you have achieved the learning outcomes for this section:

Chemistry of Hard and Soft Water. I'm sure you've heard the terms 'hard water' and 'soft water', but do you know what they mean?

Chemistry of Hard and Soft Water

Is one type of water somehow better than the other? What type of water do you have? Let's take a look at the definitions of these terms and how they relate to water in everyday life. Hard water is any water containing an appreciable quantity of dissolved minerals. Soft water is treated water in which the only cation (positively charged ion) is sodium.

This topic should be read in conjunction with the topics Like dissolves like and Talking solutions. What is dirt? Teachers' Online Primary Science. HAZCHEM signs Dangerous goods are divided into classes based on the hazards they pose.

Teachers' Online Primary Science

All packages and containers, shipping containers, trucks, trains and tankers which carry dangerous goods must carry the correct "Class Label" in the form of a diamond shaped sign. This diamond sign shows the nature of the hazard posed by the dangerous substance by color, symbol and the class of the goods by number. Water droplet bouncing on a superhydrophobic carbon nanotube array. Body Forces on Inclined Planes. Determine force required to move a body up on an inclined plane Neglecting the friction the force required to move a body up an inclined plane can be expressed with the formula Fp = W h / l = W sin α (1) where Fp = pulling force (N, lbf) W = m g = weight of body (N, lbf) h = elevation (m, ft) l = length (m, ft) α = elevation angle (degrees) m = mass of body (kg, slugs) g = acceleration of gravity = 9.81 (m/s2) = 32.174 (ft/s2) Adding friction (1) can be modified to.
