conjunction with conventional deposition techniques. This process‚ coined Ion Beam Enhanced Deposition (IBED)‚ is depicted in Figure 1 and promises a new generation of exotic coatings with superior adhesion‚ near theoretical densities‚ very high hardness‚ and‚ at the same time‚ capable of being deposited at low temperature. T he effect of the ion beam (e.g.‚ N) is to initially “intermix” the deposited atoms (e.g.‚ Ti) with the substrate for superior adhesion as well as to provide energy to the grown

“The Things They Carried‚” by Tim O’Brien‚ brings to light the psychological impact of what soldiers experience during times of war. We learn that the effects of traumatic events weigh heavier on the minds of men than all of the provisions and equipment they shouldered. Wartime truly tests the human body and mind‚ to the point where a few men return home completely destroyed. Many soldiers have been driven to the point of mentally altering reality in order to survive day to day. Furthermore‚ an indefinite

Well‚ it made me sick to see it; and I was sorry for them poor pitiful rascals‚ it seemed like I couldn’t never feel any hardness against them any more in the world. It was a dreadful thing to see. Human beings can be awful cruel to one another. In the above passage from The Adventures of Huckleberry Finn‚ by Mark Twain‚ Tom and Huck walk through the middle of a town

Alternative methods of filtration such as membrane filtration may be both more efficient in removing particles including microorganisms such as Giardia and Cryptosporidium.
