Notes on making a tricopter Posted on March 2‚ 2013 Making a Quad- or Tri-copter is a project I’ve been tempted by for a long time. Ever since I got an RC heli‚ which I’ve since abandoned. The Heli was too hard to fly‚ and there wasn’t much motivation to persevere — having learned‚ all you can really do is aerobatics‚ which I’m not very interested in. A quad‚ on the other hand‚ is easier to fly and much more flexible: I could add cameras‚ sensors‚ telemetry‚ code it to do interesting things‚ etc

side effects and limitations in point form. Drug: Lithium Lithium is the first choice of treatment for bipolar disorders and it is indicated that Lithium is effective in the alleviation of manic and depressive episodes. 75-80% of patients who take Lithium as directed show improvement. One patient‚ on page 177 of the textbook‚ states that Lithium prevents his "disastrous highs" and "diminishes depression". Patients who continue to take Lithium between episodes are significantly less likely to experience

Stoichiometry Practice Problems Be sure to balance all equations before you start calculating! Answer key is at the end. 1) Lithium hydroxide reacts with hydrobromic acid to produce lithium bromide and water. If you start with ten grams of lithium hydroxide‚ how many grams of lithium bromide will be produced? 2) Ethylene (C2H4 ) reacts with oxygen gas to produce carbon dioxide and water. If you start with 45 grams of ethylene‚ how many grams of carbon dioxide will be produced?

change that represents from gas-powered vehicles. 1. currently batteries cost about $400-600 for each unit called a kilowatt-hour. 2. Current electric cars contain batteries with up to 85 kilowatt-hours. (Transition) As I’ve shown you‚ retrieving the lithium needed for the batteries is dangerous and bad for the environment. The initial cost of an electric car is more expensive than most people can afford. And driving electric cars‚ comparatively to gas powered cars‚ isn’t really saving you any money‚
