“A brief history of chemical warfare” By Harold Maass For more than 2‚000 years. As early as 600 B.C.‚ the Athenians poisoned the wells of the Spartans‚ who later tried lobbing burning sulfur pitch over the walls of Athens‚ hoping to fill the city with toxic smoke. Genghis Khan used that same trick‚ catapulting burning sulfur pitch during his siege of fortified cities around A.D. 1200. Over the centuries‚ various armies put poisons on arrows and in bullets to make them more lethal. But it wasn’t

Overview Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years‚ it has also developed into much more advanced chemistry. In this article‚ I am going to focus on the more advanced‚ modern uses of chemical warfare in World War I and World War II. World War

There are two useful numbers that you can compute with the EAC. One of them is called Estimate to Complete (ETC)‚ which tells you how much more money you’ll probably spend on your project. And the other one‚ Variance at Completion (VAC)‚ predicts what your variance will be when the project is done. ETC = EAC - AC €11‚ 507 – €5‚ 750 = €5‚ 757 (how much the rest of the project likely to cost) Since EAC predicts how much money you’ll spend‚ if you subtract the AC‚ you’ll find out

Biological and Chemical Outline Biological and chemical warfare has been around since the beginning of time. From poison tipped arrows to purposely transmitting smallpox to individuals. There has been ongoing political conflict on biological and chemical warfare for quite some time for legitimate reasons too. Biological and chemical warfare is very deadly and sometimes inhumane‚ but on the other hand it is very cost efficient and is very effective at doing its job. Biological and chemical warfare
