Problem: Article: You can use window cleaner or rubbing alcohol. Simply wipe the tang down with your desired solution, and let it dry. Be careful not to handle the tang with your bare hands after this. Rubbing alcohol will work the best, but you can use window cleaner too. You don't have to clean the wood scales. The wood is porous and textured, so it will take the epoxy readily. You can do this with a metal file or even a screw. You don't have to be precise for this step, but you should wipe the surface down once you are done. If the scales are smooth on the marked sides, it would be a good idea to scuff them as well. You can also roughly sand the scales with 120-grit sandpaper. Make sure that you are only sanding the sides that will be touching the tang. Each brand of epoxy glue is different, but in most cases, you will need to mix equal amounts of "Part A" and "Part B" in a plastic, disposable cup. Work quickly. Most epoxy glues set within minutes. Make sure that you are using epoxy glue, and not epoxy resin or coating. Mix the epoxy using a disposable tool, as it will ruin whatever you use to stir it. It would be a good idea to wear some plastic of vinyl gloves too. You can buy epoxy glue in hardware stores. Some craft stores may also sell epoxy glue. Use a disposable knife or paint spatula to spread an even layer of epoxy onto 1 side of the tang and the marked side of the matching scale with epoxy. Press the 2 together. Working quickly, flip the knife over so that you can see the other side of the tang. Insert the pins into the holes. Coat the tang and the marked side of the remaining scale, and press them together. You may have to hammer the second scale into place to ensure a tight fit. If you want to, you can coat the pins with epoxy too. This will make the bond even stronger. Make sure that you are inserting the handle between the pieces of plastic wrap--this way, the excess epoxy won't get everywhere. Close the vise as tightly as possible. After squeezing the 2 halves together, all the excess epoxy will have leaked out. Dip a rag in acetone, and use it to wipe off any epoxy that has leaked out from between the 2 scales. How long this takes depends on the type of epoxy you are using. Some are set and ready to use within 1 hour. Others need up to 1 day to dry. Check the label on your package of epoxy for complete drying times and instructions.
Summary: Clean the tang on both sides to remove any oils or dirt. Scuff the tang on both sides to give the epoxy some texture to stick to. Prepare the epoxy glue according to the instructions. Glue the first scale to the the tang with the prepared epoxy. Insert the pins and glue the second scale. Insert the handle into the vise and clamp it shut. Wipe off any excess epoxy with a rag soaked in acetone. Allow the epoxy to set.

Problem: Article: Eczema and psoriasis both cause red patches on the skin; however, eczema has red patches that may also have a brownish or gray tint to them. The skin may also be covered in smaller bumps that are filled with fluid or that are crusty. The red patches of skin may be covered in raised bumps that look like goosebumps. The affected skin may thicken or develop knots. The color may be darker or lighter depending on the type of eczema, how long it has been affecting you, or how serious the flare up is. Eczema often makes your skin dry. Your skin may be flaky or peel off when scratched. In extreme cases, the skin may be cracked because it is so dry. The skin may crack and ooze a clear substance. The cracked skin may lead to skin infections. Eczema often occurs on the hands, wrists, feet, ankles, upper chest, eyelids, and cheeks. You may also see it on areas of the body that bend, like the inside of the elbows or knees. In babies, eczema may be on the face or scalp. Babies may also get it along the leg where a diaper sits or between the buttocks.
Summary: Monitor for red-brown patches. Check for dry skin. Identify where eczema occurs.

Problem: Article: A ratio is an expression used to compare two quantities. A simplified ratio can be taken as is, but if a ratio has not yet been simplified, you should do so to make the quantities easier to compare and understand. In order to simplify a ratio, you divide both terms (both sides of the ratio) by the same number. This process is equivalent to reducing a fraction. Example: 15:21{\displaystyle 15:21} Note that neither number in this example is a prime number. Since that is the case, you'll need to factor both numbers to determine whether or not the two terms have any identical factors that can cancel each other in the simplification process. A factor is a whole number (or expression) that can evenly divide into the term, leaving another whole number (or expression) as the quotient. Both terms in the ratio must share at least one factor (other than the number 1) or the ratio cannot be simplified. Before you can determine if the terms do share a factor, you must discover what the factors of each term are. Example: The number 15 has four factors: 1,3,5,15{\displaystyle 1,3,5,15} 151=15{\displaystyle {
rac {15}{1}}=15} 153=5{\displaystyle {
rac {15}{3}}=5} In a separate space, list all the factors of the ratio's second term. At this point do not consider the factors of the first term; focus only on factoring this second term. Example: The number 21 has four factors: 1, 3, 7, 21 211=21{\displaystyle {
rac {21}{1}}=21} 213=7{\displaystyle {
rac {21}{3}}=7} Look at the factors for both terms of the ratio. Circle, list, or otherwise identify any factors that appear in both lists. If the only shared factor is 1, then the ratio is already in its simplest form, and no further work needs to be done. If the two terms of the ratio have other shared factors, however, sort through them and identify the highest factor common to both lists. This number is the greatest common factor (GCF). Example: Both 15 and 21 share two common factors: 1 and 3 The GCF for the two terms of the original ratio is 3. Since both terms of the original ratio contain the GCF, you can divide each term by that number and come up with whole numbers as a result. Both terms must be divided by the GCF. Example: Both 15 and 21 are divided by 3. 153=5{\displaystyle {
rac {15}{3}}=5} 213=7{\displaystyle {
rac {21}{3}}=7} You are left with two new terms. The new ratio is equivalent in value to the original ratio, meaning that the terms in one ratio are in the same proportion as the terms in the other ratio. Note that the terms of the new ratio should not share any common factors between them (other than 1). If they do, the ratio is not yet in simplest form. Example: 5:7{\displaystyle 5:7} The point of all this is that the simplified ratio 5:7 is easier to work with than the original ratio 15:21.
Summary:
Look at the ratio. Factor the first term. Factor the second term. Find the greatest common factor. Divide both terms by the greatest common factor. Write down the new simplified ratio.
