  • The nonlinear absorption of a strong electromagnetic wave caused by confined electrons in cylindrical quantum wires is theoretically studied by using the quantum kinetic equation for electrons. The problem is considered in the case electron-acoustic phonon scattering. Analytic expressions for the dependence of the nonlinear absorption coefficient of a strong electromagnetic wave by confined electrons in rectangular quantum wires on the temperature T are obtained.

  • Electric charge and a measure for the quantity of charge Any household electrical appliance – be it a light bulb, a motor, or a television set – has two contacts which have to be plugged in to get the device to operate. This common characteristic, that an electrical apparatus must have two wires connecting it to a source of electricity, gave the rise in the eighteenth century to the idea that when an electrical device is working, something is moving through it. That something is called electric charge. When you pull out a plug, turn off a switch, or disconnect...

  • The extraordinary mechanical properties and unique electrical properties of carbon nanotubes (CNTs) have stimulated extensive research activities across the world since their discovery by Sumio Iijima of the NEC Corporation in the early 1990s. Although early research focused on growth and characterization, these interesting properties have led to an increase in the number of investigations focused on application development in the past 5 years.

  • This is not a normal diet book, and I am not a normal diet book author. I’m not a doctor. Nor am I a nutritionist, psychologist, sports hero, gourmet chef, or any of the other vocations that seem to qualify people to tell you how to lose weight. I’m an engineer by training, a computer programmer by avocation, and an businessman through lack of alternatives. From grade school in the 1950’s until 1988 I was fat—anywhere from 30 to 80 pounds overweight. This is a diet book by somebody who spent most of his life fat....

  • STIFF with shock, Naomi Heckscher stood just inside the door to Cappy's one-room cabin, where she'd happened to be when her husband discovered the old man's body. Her nearest neighbor—old Cappy—dead. After all his wire-pulling to get into the First Group, and his slaving to make a farm on this alien planet, dead in bed! Naomi's mind circled frantically, contrasting her happy anticipations with this shocking actuality. She'd come to call on a friend, she reminded herself, a beloved friend—round, white-haired, rosy-cheeked; lonely because he'd recently become a widower.

  • Dark meat in the can—brown, oily, and flecked with mucus—gave off a repellent, fishy smell, and the taste of it rose in his throat, putrid and bitter, like something from a dead man’s stomach. George Jordan sat on the kitchen floor and vomited, then pushed himself away from the shining pool, which looked very much like what remained in the can. He thought, No, this won’t do: I have wires in my head, and they make me eat cat food. The snake likes cat food He needed help but know there was little point in calling the Air Force.

  • All along the line of machines, the men's hands and arms worked like the legs of spiders spinning a web. They wound wire and hammered bolts, tied knots and welded pieces of steel and fitted gears. They did not look at each other or sing or whistle or talk or laugh. And then—he made a mistake. Instantly he stepped back and a trouble shooter moved into his place. The trouble shooter's hands flew over the controls. The trouble shooter finished and the workman took his place. His arms moved ceaselessly again....

  • Not all materials can be etched in an easy and cheap way. Especially, noble metals or tantalum are stable against most of these corrosive structuring methods. Hence, precision machining may be used to generate microstructures from these metals as well as from standard metal alloys such as stainless steel or hastelloy. Depending on the material, precision machining can be performed by spark erosion (wire spark erosion and countersunk spark erosion), laser machining or mechanical precision machining.

  • Ever wonder why women can brush their teeth while walking and talking on various subjects while men generally find this very difficult to do? Why 99 percent of all patents are registered by men? Why stressed women talk? Why so many husbands hate shopping? According to Barbara and Allan Pease, science now confirms that "the way our brains are wired and the hormones pulsing through our bodies are the two factors that largely dictate, long before we are born, how we will think and behave. Our instincts are simply our genes determining how our bodies will behave in given sets...
