water into steam to turn turbines‚ much like in power stations that produce energy from burning fossil fuels‚ except without the carbon dioxide emissions which contribute to the greenhouse effect and air pollution. The reactors use uranium rods as fuel and each rod can last for several years before needing to be replaced. The map on the right shows the locations of nuclear power stations in the UK‚ their generating capacity and anticipated closure dates. Natural uranium isn’t very radioactive‚ as it

Nuclear power is made up of atoms that are constructed like a mini solar system. By the late 1950’s nuclear power was developed. There are two types of uranium in nuclear power‚ the u-238 and u-235. Nuclear power plants use a lot of water to cool the rods. They also boil water into steam. Nuclear power plants get the heat that’s needed to produce steam through a physical process called Fission. Fission is

Welding Outline 1. History of Welding a. Welding can be traced back to the Bronze Ages‚ where pressure welding was first developed. b. The Egyptians were also one of the first to use pressure welding. c. The blacksmith of the middle ages was the one to bring forge welding into the world. d. Early types of welding were used for holding items together for some project. As for the blacksmith in the Middle Ages it was more for horse shoes or fixing iron material

Nuclear power stations work in fossil fuel-burning stations‚ except that a "chain reaction" inside a nuclear reactor makes the heat instead.The reactor uses Uranium rods as fuel‚ and the heat is generated by nuclear fission: neutrons smash into the nucleus of the uranium atoms‚ which split roughly in half and release energy in the form of heat.Carbon dioxide gas or water is pumped through the reactor to take the heat away‚ this then heats water to make steam.The steam drives which drivegenerators

putting up the American flag it waves yet there is no wind on the moon. Actually‚ the flag appears to be fluttering because it is hanging from a horizontal rod. This rod was thought of by NASA scientists before they brought it to the moon because NASA scientists were aware that the moon had no wind (Google Books‚ 2016). Without this horizontal rod‚ the flag would have just drooped down (Google Books‚ 2016). Also‚ when you look at it carefully‚ you notice that

Attention Getter: There are currently 442 active nuclear power reactors worldwide according to the Nuclear Energy Institute. Of all of the reactors worldwide‚ 14 have been classified as accidents where the public has been exposed to radiation. The most devastating of these incidents was the core meltdown of reactor 4 at Chernobyl‚ better known as the Chernobyl disaster. Introduction: Today I am going to tell you 3 things about Chernobyl. * First‚ I am going to tell you what Chernobyl was

12CQ014237 INTRODUCTION TO THE BACTERIAL CELL (EUBACTERIA) Bacteria (singular: bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length‚ bacteria have a wide range of shapes‚ ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth‚ and are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and

other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine‚ its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump‚ the function is reversed and force is transferred from the crankshaft to the piston for the purpose of compressing or ejecting the fluid in the cylinder. In some engines‚ the piston also acts as a valve by covering and uncovering ports in

yellow‚ orange‚ or green but they can see whites light blues‚ purples and different shades of grey. Besides just the cones‚ there are other photoreceptors known as rods. Rods can only detect black and white‚ but they also process movement extremely well and help to see in the dark. A dogs photoreceptors are mostly rods. This means they can see exceptionally well in low light conditions and see different shades of grey to a higher degree than we can. They can also differinciate the tiniest
