In one sentence, describe what the following article is about: The Clostridium tetani bacteria enter the body through cuts and broken skin.C. tetani lives in soil, dust, and animal feces. When these bacteria enter a deep flesh wound, the spores may produce a powerful toxin, tetanospasmin, which actively impairs your motor neurons the nerves that control your muscles. There is an incubation period of 3-21 days before symptoms begin to appear. The incubation period varies according to the distance the infected wound is from the central nervous system. For instance: an infected cut on the finger will have a longer incubation period than a cut on the neck. Be quick to treat deep, penetrating wounds. The bigger and more severe the injury, the easier it will be for C. tetani to enter your body. Tetanus infections occur all over the world. However, they are most common in hot, wet climates where the soil is rich with bacteria. Tetanus usually does not spread from one person to another. Nonetheless: be careful what you touch when you are walking around with an open cut or wound. If you are traveling in the developing world, you may not have access to the same caliber of tetanus treatment as you would in your home country. Ask your doctor about the "Dtap" booster vaccine for tetanus, diphtheria, and acellular pertussis. You can usually prevent infection through proper immunization with the tetanus vaccine. This is how tetanus has been largely eradicated from the developed world. In the United States, nearly all modern cases of tetanus occur in adults who were not vaccinated as children, or who have not received a vaccination in the past ten years.
Summary: Know how tetanus spreads. Be careful when traveling. Get vaccinated.

In one sentence, describe what the following article is about: (You can also place your thumb behind the first valve and this will give you the maximum function of your fingers to press the key down.) This thumb will support some of the weight of the trumpet. It should be placed beneath the lead pipe, or the pipe which attaches to the mouthpiece. Do not bend your thumb, as this can restrict the movement of your other fingers. Some instructors will recommend that you keep your thumb rested against the first valve casing rather than between the first and the second. This technique is designed to help you keep your thumb straight and should not affect the way the trumpet is supported. Pressing different combinations of valve keys is how you play different notes. Using the balls of your fingers, press down the keys that correspond to the notes you wish to play. Rest your fingers on the keys when you're not playing. Think of keeping them in the shape of a claw. Curving your fingers will give you the flexibility to play notes quickly. Even if you're just beginning, practicing this technique from the start will help you as you advance to more complex musical pieces. Your band director will instruct you on the different fingerings used to play notes, or you can use a music book or search for a fingering chart online. It may seem convenient to place your little finger in the finger hook, allowing it to hold some of the weight of the trumpet. However, this will affect your ability to move your fingers freely, especially your ring finger on the third valve. It's fine to use the finger hook temporarily if you need to use your left hand to turn a page of music or reach for a mute. Just try not to get in the habit of doing it all the time. Make sure that you are keeping your right wrist relaxed. Stiffness in your wrist will affect your ability to press down the valves, and it may lead to wrist pain after long periods of holding the trumpet.
Summary: Rest your right thumb between the first and second valve casings. Strike the valve keys with your right index, middle, and ring fingers. Round the fingers of your right hand as you play. Avoid resting your right little finger in the finger hook. Relax your right wrist.

In one sentence, describe what the following article is about: Use the remote or close the door manually. This will allow you to access the tracks and the rest of the moving parts on your door. Before lubricating your door, you'll want to make sure that it's not on. Disconnect your garage door from the power source after you close it. If the plug to your garage door opener is hard to reach or hard-wired, turn off the breaker that controls it in your circuit box. The tracks are what the garage door rollers ride on to open and close. You don't want to lubricate these, but you do want to make sure that they are completely cleaned out for your door to operate correctly. Wipe down the inside of both tracks and remove any dirt and debris. Make sure that there is no debris left in your tracks that the rollers can get stuck on. Use an automotive brake cleaner to loosen and wash away grime. If you are having issues getting debris out of the tracks, you can use a vacuum with a hose extension to suck out the dirt and debris. This is a great solution to reach the higher portion of the tracks that you may be having issues reaching.
Summary:
Close the garage door. Cut power to the door. Clean out the tracks with a damp rag. Vacuum out dirt and dust from your tracks.
