INPUT ARTICLE: Article: Obesity has been linked to kidney damage. If you are overweight, or are afraid you are going to become overweight, exercise daily. When you are overweight, your kidneys have to work overtime to keep you healthy. You should try to exercise for 30 to 45 minutes, four or five days a week. Some exercises you can incorporate into your work week include running, cycling, swimming, and walking. Try to pick one (or a couple) that you enjoy so that you are more motivated to work out each day. If you are elderly, the recommended exercise each week is 15 minutes for three days a week. . Tobacco smoke does serious damage to your kidneys. There are more than 4000 particles and gases found in cigarette smoke, many of which can damage your kidney. Cigarettes are also linked to kidney fibrosis, which is when your kidney tissue turns hard, causing kidney failure. Cigarette smoke can also cause hypertension, which is elevated blood pressure. Alcohol can also cause kidney damage. When metabolized, alcohol becomes aldehyde, a harmful chemical that can hurt your kidneys and liver. Alcohol also increases your chances of heart disease and diabetes. Any drug that you put in your body gets absorbed by the blood and then filtered by the kidneys. These drugs can have a harmful effect on your kidney and could lead to kidney failure if your kidneys have to process too many harmful toxins. For example, cocaine may cause myolysis. Myolysis is the breakdown of muscle mass, which can result in kidney failure. This is particularly important to do if your bacterial infection is in your kidney or urinary tract. You will have to take antibacterial medication to treat these conditions, but it will be well worth it, as a kidney dealing with a bacterial infection can be a major health risk.

SUMMARY: Exercise regularly. Avoid smoking Stop drinking alcohol. Avoid drug abuse. Treat any bacterial infections you have.

INPUT ARTICLE: Article: The manufacturer's part number should be listed on the case of the relay. Look up the applicable data sheet and determine the voltage and current requirements of the control coil. This also may be printed on the case of larger relays. A diode around the pole is often used to protect the logic circuitry from damage due to noise spikes. The diode will be shown on drawings as a triangle with a bar across one corner of the triangle. The bar will be connected to the input, or positive connection, of the control coil. This will also be available from the manufacturer's data sheet, or may be printed on the case of larger relays. Relays may have one or more poles, indicated in drawings by a single line switch connected to a pin of the relay. Each pole may have a normally open (NO) and or normally closed (NC) contact. The drawings will indicate these contacts as connections with a pin on the relay. The relay drawings will show each pole as either touching the pin, indicating a NC contact, or not touching the pin, indicating a NO contact. Use a digital multimeter (DMM) to test the resistance between each pole of the relay and the corresponding NC and NO contacts for that pole. All NC contacts should read 0 ohms to the corresponding pole. All NO contacts should read infinite resistance to the corresponding pole. Use an independent voltage source appropriate for the rating of the relay coil. If the relay coil is diode protected, make sure that the independent voltage source is connected with the proper polarity. Listen for a click when the relay is energized. Use a digital multimeter (DMM) to test the resistance between each pole of the relay and the corresponding NC and NO contacts for that pole. All NC contacts should read infinite resistance to the corresponding pole. All NO contacts should read 0 ohms to the corresponding pole.

SUMMARY: Determine the coil requirements of the relay. Find out if the control coil is diode protected. Assess the contact configuration of the relay. Test the de-energized condition of the relay contacts. Energize the relay. Check the energized condition of the relay contacts.

INPUT ARTICLE: Article: When visiting a dentist, most will recommend you purchase a sonic electric toothbrush, or a brush that can create thousands of oscillations per minute. These provide a deep, thorough cleaning at a reasonable price, with many models costing under $100. Popular sonic toothbrush brands include Sonicare, ISSA, and Oral-B Pro. While similar in design to sonic brushes, ultrasonic brushes create millions of oscillations per minute instead of thousands. Though typically more expensive than their sonic siblings, coming in at well over $100, they provide the best cleaning possible short of visiting an actual dentist. Popular ultrasonic brands include Smilex, Emmi-dent, and Ultreo. Companies often use the terms sonic and ultrasonic interchangeably, so check the brush's oscillations per minute to make sure it is actually ultrasonic. If you're sick, traveling, or otherwise in need of a cheap, disposable electric toothbrush, try purchasing a basic battery-operated one. Though low-powered, they typically cost only a few dollars, making them a great option for flights, sleepovers, and other times when your normal toothbrush won't be available. If you're getting an electric toothbrush for a child, try buying one themed around their favorite TV show, video game, singer, or cartoon character. These brushes typically cost only a few dollars, meaning you can replace them easily when damaged, and often include timers to make sure the child brushes long enough. These brushes are typically low-intensity, so kids with severe teeth issues may need something more powerful.

SUMMARY:
Purchase a sonic toothbrush for an inexpensive, dentist-approved option. Get an ultrasonic toothbrush for the best results possible. Buy a cheap electric toothbrush to have something disposable. Grab a themed toothbrush for kids.
