Article: Before so much as jacking up the vehicle, you need to remove the axle nut. Start by removing the hubcap for the respective wheel of the CV axle to be replaced. For vehicles with rims, you may simply have a cap at the center of the wheel rather than a hubcap. If your vehicle has a cotter pin securing the axle nut, you will need to remove it. The pin will resemble a bobby pin with the ends folded back to hold it in place. You will need to use pliers to straighten the two bent ends of the cotter pin before you can remove it. If the pin is stuck, try spraying it the a penetrating lubricant from a hardware or automotive store. The lubricant should actually help with the axle nut as well. Once the cotter pin is out, you can remove the axle nut. The nut will take significant torque to remove, which is why it is much safer to remove the nut before jacking up the vehicle. Unfortunately, axle nuts do not have a standard size, and the socket size required will be different for different vehicles. The parts department at a certified dealership for your vehicle make should be able to tell you the exact size if you want to check before starting the project.

Problem: Article: According to the U.S. Centers for Disease Control and Prevention (CDC), you should give children two doses of MMR at different times to prevent measles from occuring. Give the first shot of MMR to children between 12-15 months of age, and the second shot between 4-6 years old. Kids need both doses to have the best immunity. As long as the second dose is 28 days after the first dose, children can get the second dose earlier. The important thing is to give two shots at least 28 days apart. Children between the ages of 1-12 years can get the MMRV vaccine instead, which covers varicella (chickenpox) as well as measles, mumps, and rubella. Teens who attend college or another post-high school institution should be able to show evidence of immunity to measles, mumps, and rubella. If not, administer two doses of MMR at least 28 days apart. "Evidence of immunity" is when your patient can show written proof that they have been vaccinated, have had all three diseases, or have had blood tests done showing they are immune to all three diseases. Check your patient's medical records or try to consult with their previous doctor. Give one dose to adults who cannot demonstrate evidence of immunity. Adults born before 1957 do not need the vaccine, however.
Summary: Administer MMR to children at 12-15 months and 4-6 years of age. Ensure teens are up to date on their MMR vaccine. Vaccinate adults who are not immune.

INPUT ARTICLE: Article: This can mean in a clinical laboratory setting. You can find suitable laboratories at most colleges and research institutions. Working at home is also possible but requires caution - manufacturing your own biodiesel may be illegal and can put your house at risk of a fire, smoke or carbon monoxide. A good work place will be well-ventilated and have clear access to running water, eye-wash stations, fire extinguishers, spill containment supplies, a fire alarm and a telephone to use in case of emergencies. Most laboratories will have posted dress instructions you should follow. You should always wear a long-sleeve shirt, long pants, and shoes in any laboratory setting. When making biodiesel, you should also wear a heavy-duty apron, chemical-resistant gloves (butyl rubber is best when handling methanol and lye) and protective goggles or eyewear. The gloves should come up to your elbows or have cuffs you can pull over your long-sleeve shirt. The easiest oils to use for biodiesel are neutral vegetable oils like canola, corn, and sunflower oil - these oils are readily available at grocery stores and have a low melting point, which means they won't solidify if they get too cold. Avoid using peanut oil, coconut oil, palm oil, tallow, and lard. These sources of oil solidify at relatively high temperatures. Biodiesel usually has a lower melting point than the oil it's made from, but these oils can still be difficult for beginners. Also avoid olive oil. It, peanut oil, palm oil, tallow, and lard all contain more acids than in the recommended neutral oils. These extra acids can interfere with the reactions that take place to create the biodiesel. It's also possible to use waste vegetable oil which has been used for cooking. However, waste oil should be filtered to remove particulates, then allowed to settle for 24 hours to separate the oil from any water or other impurities. Pure oil will be clear and bright, with no sediment. Only use containers for making biodiesel - don't use them for storing food afterwards, even if you wash them well.

SUMMARY: Work in a safe place. Observe laboratory dress codes. Obtain good-quality oil. Ensure all containers are well-labeled.

This works well with baggy sweaters as well as more fitted ones. For the best look, wear a denim shirt with longer sleeves so you can roll the bottoms up over the cuffs of the sweater. Make sure to pull the collar out so it's visible over the sweater. Cardigans work well for this look, too. If you're worried about looking or feeling bulky because of the multiple layers, try tucking the denim shirt into your pants. This will help hold the shirt down so it doesn't bunch up under the sweater. This is a great way to dress down an outfit or show off a cool shirt. Stripes look great with denim, but don't be afraid to wear a graphic tee or something bright and patterned. Stick with neutral tones if you want to maintain a classic look. This essentially turns your denim shirt into a cardigan or jacket. If the weather is cool, you could even wear a long sleeved shirt under the denim one and roll the bottom cuff up over the denim cuff. This creates a nice visual effect between the 2 shirts. This is a really popular style for both men and women to wear to the office. You can button the blazer to make it look a little more fitted, or leave it unbuttoned to show off your layers even more. Make sure to pair your blazer with bottoms that complement the entire outfit. For example, you could wear a navy blue blazer, a light-denim shirt, and a pair of khakis for a neutral yet classy style. Try just tying together the bottom of the shirt rather than buttoning it up, that way the top of the dress will still be visible. If you get warm, you can take off the top and tie it around your waist. This is a great way to transition your maxi-dresses from summer to fall. You have an extra layer in case you get cold, and it lets you enjoy those dresses for a few extra weeks before it gets too cold to wear them. You could even wear a maxi-shirt and a tank top and put the denim shirt on over the tank top for a very similar effect. If the temperature is cool, don a puffy vest overtop of your denim shirt the next time you head out. Leave your denim shirt buttoned, but leave the vest unfastened. You could even add a scarf to the outfit for additional warmth. Pair the vest and denim shirt with black jeans or leggings to really pull the look together.
