Article: If it's something else, you will probably need to visit the doctor to check what it might be. Chest pain, particularly coupled with arm pain or shortness of breath, might be a heart attack. Classic GERD symptoms include: Heartburn Hoarse or dry throat Difficulty swallowing Acid reflux (food or sour liquid coming back up into your mouth) This would mean if you are having to take antacids or other heartburn remedies more than twice a week. Keep in mind that many women experience these symptoms during the early stages of pregnancy -- GERD and morning sickness often present as the same ailments. New mothers should see a doctor if GERD symptoms don't decrease after giving birth. If you have made diet and lifestyle changes that should keep the GERD in check, yet it continues, seek medical attention. Discuss possible next steps with your doctor. In some cases, GERD will require surgery to completely cure it. Surgery to cure GERD would fix the lower esophageal sphincter (LES), allowing it to close properly after your body has processed your food. It can be performed laparoscopically, requiring minimal incisions and requiring a short hospital stay. Without treatment, GERD can eventually lead to more dangerous complications. One of the most common is "Barrett's esophagus," a condition that increases the risk of esophageal cancer.

Make sure you are experiencing the symptoms of GERD. Seek medical attention if these symptoms occur often. Visit your doctor if GERD continues.
Article: This instrument measures how much moisture is in the air or the relative humidity in an environment. It uses the cooling effect of evaporation to determine the relative humidity. Relative humidity is the ratio of water vapor in the air relative to the amount that could possibly be there, at a certain temperature. When you walk through fog, for example, you are experiencing 100% humidity. If you walk through a desert, you are experiencing around 10% humidity. To make your own sling psychrometer at home, you will need: Cotton gauze, in pads rather than balls A pair of scissors A small rubber band A liter empty plastic soda bottle Clear plastic tape 2 red alcohol Celsius thermometers Water An 18in (46cm) piece of string Use the water to moisten the gauze. This will help you capture moisture in your sling psychrometer. Cover 1 bulb of the thermometers with the wet gauze using a rubber band. Take the thermometer covered in gauze and place it on 1 side of the plastic bottle. Then, secure it there with tape. Take the other thermometer and attach it to the other side of the bottle using tape. Make sure you can still see the numbers and the red alcohol in the thermometers. Make sure the string is tied well on the the top of the bottle, as you will be holding it and spinning it to get a reading on your sling psychrometer. Hold tightly to the end of the string and spin the bottle in a circle in an open-air space. Do this for 1 minute. Then, record the temperatures on both thermometers. Record the 2 temperatures and then subtract the lower temperature from the higher temperature to determine the temperature difference. You will likely find that the thermometer with the wet gauze will always have a lower temperature than the thermometer with the dry bulb. The wet bulb temperature will always be lower than the dry bulb because water evaporates from the wet bulb when you spin the 2 thermometers. The evaporation then cools the wet bulb. The drier the air is, the more water will evaporate from the wet bulb, leading to a higher temperature difference between the wet and dry bulb. For example, you spin the sling psychrometer outside and the dry thermometer has a temperature of 22 degrees Celsius. You get a wet bulb temperature reading of 12 degrees Celsius. If the weather is very humid one day, you may get a dry bulb temperature of 22 degrees Celsius and a wet bulb temperature of 21 degrees Celsius. Because there is very little water evaporation on the wet bulb, this indicates that there is high humidity outside.

Be aware of the purpose of a sling psychrometer. Gather your supplies. Wet a double layer of cotton gauze. Attach the thermometers to the plastic bottle. Tie the string to the top of the bottle. Determine the difference between the 2 temperatures.
