In one sentence, describe what the following article is about: Steam is one of the most widely used and effective methods for sterilizing needles. No living thing can survive direct exposure to saturated steam at 250 degrees Fahrenheit (120 degrees Celsius) for longer than 15 minutes. Use a steaming pot to do this. Put water in the bottom pot. When it starts to boil, place the needle in the pot with the holes over the boiling pot, then cover it with a lid. Let it steam for at least 20 minutes. An autoclave is a tool specifically made for sterilizing needles and other tools by steam. If you need to sterilize needles often and precisely, you may want to invest in one. Wrap the needle in multiple layers of clean cloth. Bake the needle for 1 hour at 340 degrees Fahrenheit. This is one way to completely sterilize the needle by killing all the microorganisms. Make sure you leave it in the oven long enough. This method can be used to sterilize needles used for acupuncture, medical use, and piercings and tattoos. Dry heat can cause the needle to become brittle. Use a gas-fueled fire because they leave less residue behind. Place the needle tip in the flame until it glows red. Sterilizing a needle in a flame is good for home use, but doesn't get completely sterile because the needle can pick up contaminants in the air afterwards. If there are any soot or carbon deposits on the needle, wipe it with a sterile gauze pad. This method is effective for removing a splinter, but is not the most sterile. Therefore, it is not recommended for piercing, tattooing, or medical uses. One way to sterilize a needle is to drop it in boiling water. After you wash and rinse your tools, cover them with water and boil for 20 minutes. Start counting the 20 minutes after the water has reached a boil. You can sterilize a needle by using chemicals. Soak in the mixture for at least 20 minutes, unless it's drinking alcohol. If you use drinking alcohol, soak it in that solution for an entire day. You can rinse the needle in the following chemicals: Bleach. If it's 5% available chlorine, you can use it undiluted. If it is 10%, use 1 part bleach to 1 part water; for 15%, use 1 part bleach to 2 parts water. If you don't have bleach, use one of the following chemicals: ethanol (medical alcohol) 70%, isopropyl alcohol 70%, or hydrogen peroxide 6%.
Summary: Use steam. Bake the needle. Use fire. Boil the needle in water. Use chemicals.

Get a firm chair to sit in that allows your hips to be slightly higher than your knees. Sit with your back straight and tall; imagine that a string is attached your head and it's pulling your head up. Engage your tummy muscles to straighten your spine in your lower back. As you play, use your eyes to look at the strings. Try not to drop your neck to avoid injuring your neck in the long term. Spread your knees to make enough room for your cello. Bring the cello in and allow it to balance on its end piece while resting its sides between your knees. Face the cello out so its strings are away from you. You shouldn't grip the cello tightly with your knees; simply let it balance there. The Cello should lay evenly on both legs Allow the cello to lean back against you. Position it so that the top of its body reaches your chest and can rest there. You may have to adjust the endpin, or piece at the bottom that touches the floor, so your cello is the right height for you. Simply loosen the screws and slide the endpin in or out depending on if your need the cello to be taller or shorter, then tighten the screws again before standing the cello back up. Lean your cello back and position its neck in line with the left of your head. Hold the neck with your left hand and rest your right hand on your right leg. Right-handed and left-handed people hold the cello the same way. Using your left hand, angle your cello so its strings are facing slightly toward your right. This will make it easier to reach all the strings without slouching as you play. Check to see if any parts of your body feel tense or uncomfortable. If they do, you should make adjustments to your posture, the height of your chair, or the height of your cello until you are comfortable holding it.

One-sentence summary -- Sit tall in a firm chair. Balance the cello between your knees. Rest the cello body against your chest. Angle the cello so the neck is to the left of your head. Face the cello slightly toward your right so you can easily reach the strings.

Q: Instagram does not allow you to post clickable links in actual ads. Therefore, make sure you include a link to your website in your company's bio. In the text of your ads, tell users to click on the link in your bio for more information. Update your links regularly as your website changes. Make you use language in posts that will entice users to stop and read your ads. Clearly and concisely describe what your product is and use words that draw attention. For example, something like, "Incredibly savings - up to 50% off!" can grab a users attention. If you're trying to get users to take a specific action, download a Call To Action button. This takes them to a website after it's clicked, where they can do things like purchase your products or download your apps. This can be a great way to make your ads effectively translate to sales. Use the right language in your button. For example, if you're advertising a hotel, have a Call to Action button that reads "Book Now." Find the Call to Action button through your Instagram business account settings.
A: Link to your website in your bio. Use attention-grabbing language in posts. Add a call to action button.

Problem: Article: Read the number and count how many digits are in it, paying special attention to the digits that come after (to the right of) the decimal point. Example: Write 531.94 in expanded form. Read the number: five hundred thirty one and 94 hundredths. Notice that there are three digits before the decimal point and two digits after the decimal point. There will be a total of five separate places in the expanded form of this number. Rewrite the number, separating each individual digit by a plus sign. For now, write the decimal point, too. Note that the decimal point will eventually be removed, but you should keep it in place for now to prevent confusion while solving the problem. Leave some space in between the digits and the plus signs. More information will need to be written there. Example: The number 531.94 temporarily becomes: 5 + 3 + 1 + . + 9 + 4 Label each digit with the place value name that matches its position in the original number. When working before (to the left of) the decimal point, work from the lowest number to the highest. When working after (to the right of) the decimal point, work from the highest number to the lowest. Example: You will need to count three places to the left and two places to the right. For the left values: The smallest number is 1, which matches the ones (1) place. The second number is 3, which matches the tens (10) place. The largest number is 5, which sits in the hundreds (100) place. For the right values: The largest number is 9, which sits in the tenths (10) place. The smallest number is 4, which sits in the hundredths (100) place. All of the digits on the left side of the decimal point must be multiplied by their matching place value. Do that now. Example: [5 * 100] + [3 * 10] + [1 * 1] = 500 + 30 + 1 All of the digits on the right side of the decimal point must be divided by their matching place value. Do that now. Example: [9 / 10] + [4 / 100] = 0.9 + 0.04 Combine all of your rewritten values together, placing plus signs in between each one. Remove the decimal point. This will be your final answer. Example: The expanded form of 531.94 is: 500 + 30 + 1 + 0.9 + 0.04
Summary:
Look at the number in standard form. Separate the digits. Identify each place value name. Multiply the left digits by the appropriate value. Divide the right digits by the appropriate value. Write your final answer.
