Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

Before this time‚ the atmosphere had a very different chemical make-up‚ high in carbon molecules; unsustainable for life as known today. These prokaryotes

David Harrison Project Planning & Management Assignment Air Foil Bearing Review All Air Foil Bearings (AFB) in general fit in one of two categories‚ hydrostatic and hydrodynamic. Hydrostatic bearings require a pressurised air feed in order to lift of the foil surface but offer improved performance on start up and rundown [1] while developing no more drag than and equivalent hydrodynamic bearing. Hydrodynamic bearings generate their air film purely through the rotation of the shaft. This

Trends in the Periodic table March 24‚ 2013 Four trends that will be covered: Atomic size Ionization Energy Electronegativity Electron Affinity Each of these has a group trend and a period trend A group trend refers to what is happening with the atom as you travel up or down a column of the periodic table. A period trend refers to what is happening with the atom as you move left or right across a row of the periodic table Atomic Size When discussing an atom’s size‚ usually the

educator Friedrich Froebel designed‚ the organic unity of a Japanese building Wright saw at the Columbian Exposition in Chicago in 1893‚ and a Jeffersonian belief in individualism and populism. Always a believer in architecture as "natural" and "organic‚" Wright saw it as serving free individuals who have the right to move within a "free" space‚ envisioned as a nonsymmetrical design interacting spatially with its natural surroundings. He sought to develop an organic unity of planning‚ structure‚ materials
