Summarize the following:
A pilonidal cyst is a bump that pops up at the top of the cleft of the buttocks. The pilonidal cyst can get infected and turn into an abscess, which means it will fill with pus and need to be drained. A pilonidal cyst usually occurs due to ingrown hairs or other debris trapped beneath the skin. Pilonidal cysts occur most commonly in men in their twenties and thirties. They also can occur in people who have to sit a lot and have sedentary jobs, such as truck driving and office work. Pilonidal cysts also occur more commonly in people with a lot of body hair or with coarse, stiff hair. These types of hair can puncture a cyst more easily. Other risk factors include being overweight or obese, if you have recently experienced local trauma or irritation, a deep natal cleft (the groove between the buttock), or if there is a family history of such disease. If a pilonidal cyst is not infected, there are usually no significant symptoms; however, if an imbedded hair punctures the cyst, either because you are sitting too much, wearing tight clothing, or some other unknown factor, the cyst can become infected. If you are experiencing any of these symptoms, you should see a physician as soon as possible. When the cyst becomes infected, you may experience: Swelling Pain Redness Drainage with a nasty odor Fever Formation of a cavity which may contain granulation tissue, hair, and debris

summary: Learn what a pilonidal cyst is. Determine if you are at risk. Recognize the signs and symptoms of pilonidal cysts.

Some SIM cards do not display their number inside the settings of any phone. For these cases, you may have to call the service carrier of your SIM card and ask. If you are calling from a phone with the mystery SIM card, the carrier may be able to detect the number automatically. If not, have the SIM card at hand so you can read aloud the serial number. Use the SIM card whose number you want to know. Any phone with caller ID will detect the number of your SIM card, unless you are using a private number.

summary: Call your service carrier. Send a text message or call another phone.

The hoses from your torch should attach to the nozzles on the oxygen and acetylene tanks. Typically, oxygen tanks and hoses are green, and acetylene hoses are red. The hoses are usually paired together, and the ends are separated so they can attach to their respective tanks. The acetylene hose will have reversed threads and a male fitting to make it easier to tell them apart. Since the fittings are made of brass and can easily be damaged, tighten them with an appropriately-sized wrench. To check that the regulator is completely off, back the tee handle out a few turns. This handle will be on top of the tank right next to the regulator valve. This will help ensure that you have complete control over the acetylene gas pressure. At higher than 15psi (100kPa), acetylene becomes unstable and may spontaneously ignite or explode. Again, it's extremely important to maintain control over the flow of the acetylene, so you want to open the gas valve just enough to allow a constant, steady flow of the gas. Opening the tank more than a single turn could lead the gas to become unstable, and it will be harder to turn off in the case of an emergency. This is the same handle that you closed before opening the gas valve. You should open this very slowly, and you should constantly monitor the low-pressure gauge while you're opening the valve. Open it only until the pressure indicated is between 58psi (3455kPa). To vent the atmosphere from the acetylene hose, open the gas valve on the cutting torch handle until you hear gas escaping, then observe the low-pressure gauge to see if the pressure remains steady during flow and ensure that you have this regulator set correctly. Close the acetylene valve on the torch once you are sure the pressure is regulated.. In the same way that you closed the acetylene regulator, back the oxygen regulator gauge out a few turns. Once you've done that, turn the handle on the main oxygen tank so it's all the way open. The setup on top of the oxygen tank will be similar to that on the acetylene tank. The oxygen valve is a double-seated valve. When you open it, be sure to turn the handle so the valve is all the way open. Otherwise, the oxygen will leak out around the valve-stem O-ring. Just like with the acetylene regulator, you'll turn the tee handle very slowly, watching the low-pressure gauge as you do so until the pressure reads between 2540psi (170280kPa). There are 2 valves on the oxygen side of the cutting torch assembly. To begin with, open the valve closest to the hose several turns to ensure sufficient oxygen is available for both functions. Next, open the forward valve slightly until the hose is purged (about 3-5 seconds for a 25 feet (7.6m) hose), then close the forward valve. The valve near the hose connections will control the flow of oxygen to the mixing chamber for the combustion, so no oxygen should vent from the torch tip until either the cutting lever is depressed or the valve further up the torch is opened.
summary: Hook up the gauges to the appropriate tanks. Make sure the acetylene regulator is turned off. Open the gas valve on top of the acetylene tank with one turn of the wrist. Open the regulator valve by turning the tee handle clockwise. Open the gas valve on the torch handle to vent it. Turn the oxygen regulator off, then open the main oxygen tank all the way. Open the oxygen regulator valve slowly. Open and close the oxygen valve on the torch to vent the atmosphere.
