Wire

biomechanics and physics come in. Brackets and Wires You can easily understand the physics behind the brackets and wires. Isaac Newton’s third law of motion states that every force creates an equal and opposite reaction. In context, the bracket and wire system is about application of force onto the teeth and the teeth’s reaction to the force in an opposite direction. Orthodontists attach brackets to the teeth, and secure them with an arch wire. As the wires are U-shaped, a…

surgical procedure on Mr. Inouye which involved placing a stainless steel wire which was expected to ultimately break but not expected to cause any physical damage. Two years after the operation, X-rays showed the wire had broken into smaller than expected pieces and one piece had lodged itself within the lower spine within the dura and the sheath encasing the spinal cord. Mr. Inouye required further surgery for removal of the wire fragments and he brought this suit alleging medical malpractice.…

(most infections can be treated with anti-biotics) if the infection gets bad small bits of infected material attach itself to the pacemaker wires spreading to the valves. If this happens the device must be removed. On rare occasion the pacemaker can damage the heart. As the wire is being moved from the right atrium through to the right ventricle, the wire could accidently hit the tricuspid valve resulting in the valve leaking. If it is hit, blood could accumulate stopping the heart from beating…

method to straighten your teeth. It is great alternative to traditional metal braces. The use of wire hardware to straighten teeth is notorious for its discomfort and impracticality. Not only that, but it also carries the possibility of other, more serious problems, such as plaque build-up, tooth/bracket breakage or even tooth loss, due to decay from not being able to clean your teeth properly under the wire obstruction. The Invisalign system is much more comfortable, practical and stylish than…

Wire coated breeds such as Border Terriers and West Highland Terriers have a coarse water resistant coat that can become easily matted and dirty. Their wire coats are made up of a combination of a short, soft dense undercoat and a layer of long wiry guard hairs on top. The top coat and undercoat grow at different rates and do not shed very much but they should be brushed regularly to remove any dead hair, loose undercoat, dry dirt and tangles. When the top coat has stopped growing and died it…

one lead-in wire that is soldered or welded to the rim of the base interior. The other lead-in wire is soldered to the center contact. The two portions are insulted from each other by a glass insulator, which appears as a black ring around the center contact. The next component is the steam press. The lead-in wires in the glass lightbulb have an air tight seal in the steam press. At this point the wires are made out of a nickel-iron alloy core and a copper sleeve to assure that the wires have…

shoulder, I confidently detached the old thermostat before releasing the two wires that protruded from a hole in the wall. I briefly inspected the new thermostat before getting…

central lumen through which a movable guide wire may be passed and an outer channel through which the dilation balloon is inflated. This type of catheter is advantageous if the catheter needs to be replaced with a catheter of a different size during the procedure. The guide wire can be left in place, the original catheter removed and the new catheter can then be threaded over the wire. However there can be difficulties in maintaining the position of the guide wire during the catheter exchange…

house flies from entering the house and becoming a pest. The outlined method for testing fly screens would be to place them in isolation with the exit being through a wire mesh with varying wire thickness and gaps. Pulling data from a similar experiment (Busvine, 1965), we can assume that 10 wires per linear inch combined with a wire thickness of 0.274 mm and gap of 2.17mm would stop all flies from entering the home. The investigated solution satisfies the constraints of ethics, environmental/…

with his famous mobiles he also did sculpting with wire, sheet metal and other various materials. Most of them were three dimensional, playful, and looked like spidery lines and curves, similar to his mobiles. Calder was a very talented man, so his art just wasn’t wire and sculpting. Alexander Calder also was into making jewelry with wire in the 1930’s. His first jewelry was made for his mother as a birthday present! Calder made it with brass wire and string and lots of broken…
