Third, use the nail file to smooth any rough areas and slough off dead skin. Also, file down the free edges of the natural nail to make them very short. Filing should be corner to center because the nail plate is flexible and may break down. After cleaning, cutting and filing, the nails are ready for nail tips. The first step in applying nail tips’ process is placing a small dab of glue on the tip of the acrylic nails.
A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding. TIG can be used with pure helium or argon as an inert shielding gas to protect the weld pool from the atmosphere. (Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.)
Use the 1.0mm opening for 1.6mm fiber. Also trim the Kevlar to the ‘C’ length using the electrician style scissors. * Using the marker pen and the template card provided, measure and mark the buffer strip length as shown on the template. * Using the buffer strippers, strip off the buffer in at least two pieces. * Using a dry, lint-free wipe; Remove any remnants of the protective coating on the fiber after stripping the buffer.
Abstract The objective of the south street seaweed experiment is to make a tincture of iodine. Iodine is used commercially as an antiseptic on cuts and scrapes of the skin. Conceptually, one of the active ingredients of the tincture, iodide, can be extracted from seaweed. By adding the seaweed to water and applying heat energy into the mixture, we were able to extract iodide. After adding Iodine salts, and filtering the mixture our next goal was to test for three important chemicals that must exist in our mixture for it to be a true iodine tincture; Iodine, Iodide Ion and the triiodide ion.
Introduction The element Chromium is very important in the industrial world. It is used in nonferrous alloys such as stainless steel, in order to increase its hardness and prevent corrosion and oxidation. Chromium is only found in one ore, the mineral Chromite. Chromite’s composition is iron magnesium oxide [(Fe, Mg) Cr2O4]. Occasionally, magnesium will substitute for iron, and aluminum and ferric ions will substitute for chromium.
First of all, a pharmaceutical product can be made from seaweed by heating seaweed in water. This causes the product to be extracted from the seaweed. After that, filtration is needed to extract the seaweed from the water. Finally, by evaporating the product can be extracted from the water. 2.
Fiber can also carry over a longer distance with low attenuation. They can range from 300 meters to 40 kilometers. Fiber cables also give more security; it doesn’t radiate signals and is very hard to tap. A couple of disadvantages would be the cost of the fiber optic wire and the weight. One of the biggest disadvantages is not being able to make connections as easy as the copper.
This light is lost in the cladding of the receiving optical fiber. Core diameter mismatch loss is typically only a concern with multimode optical fiber. To avoid core diameter mismatch make sure to check the cores of your fiber and make sure they are the same size to the best you can. Intrinsic factors that can affect connection performance in fiber-optics come in many types. A numerical aperture (NA) mismatch occurs when the NA of one optical fiber is different from the NA of the other optical fiber.
[Stephen] Horton [a seismologist at the University of Memphis] and others investigated a swarm of earthquakes in 2010 and 2011, including one of magnitude 4.7, in an area of central Arkansas where fracking was being conducted. The scientists found that the earthquakes were probably caused by fracking and the disposal of waste liquids from the process into other wells.” (Mead) Furthermore, air pollution is another factor that must be taken into consideration. Near the end of the well development process, something happens called flaring. Flaring is used to get rid of the waste gas that is not able to be used. The gas is purposefully set on fire, leaving flames to spew far into the sky, burning for several days continually.
When working in a microbiology lab, it is important to contain spills and discard materials properly. Describe how a spill should be cleaned up safely in a microbiology lab. (3 pts) Alert people in immediate area. Put on protective equipment. Cover area with disinfectant soaked-paper towels or with dry disinfectant.
