article: Peak flow meters only work properly if air is able to freely pass through them. Blowing into a meter that is obstructed by a foreign object will not provide an accurate reading and could cause unnecessary strain on your lungs.  Peak flow meters usually have an open orifice in the mouthpiece of the device; this is the area most likely to become obstructed, so check here first before use. When grasping the meter in your hand, make sure your fingers do not obstruct the sliding scale on top of the device. It is important to maintain good posture while using your peak flow meter because this will allow you to maximize your pre-test inhalation as well as your exhalation (which is measured by the device). Slouching or lying down while using the meter will not allow you to get a good reading. The sliding cursor on the back of the peak flow meter is what measures the force of your exhalation. If you do not zero the cursor before you use the meter, your reading will not be accurate. You can adjust the cursor by simply placing your finger on it and manually sliding it to the "zero" end of the scale, which is toward the mouthpiece of the meter. In order to register the most powerful exhalation you are capable of, you must first fill your lungs with air. Do this before inserting the peak flow meter into your mouth in order to ensure the fullest inward breath possible. Be sure to remove gum or anything else from your mouth before inhaling. Not only do you want to prevent blowing a foreign object into your peak flow meter, but you also don't want to accidentally inhale anything when you take your deep breath in. In order to get the best reading possible on the meter, you should place the mouthpiece between your front teeth and seal your lips around the opening. This will stabilize the meter and ensure that no air escapes from the sides of your mouth when you exhale. Pull your tongue backward, away from the mouthpiece, so you do not accidentally block the opening of the meter. The idea here is to get a hard, fast burst of air out of your lungs to push the sliding cursor on the meter as far as possible down the length of the device.  This means that your initial burst of breath is the most important for getting a good reading.  Don't worry about blowing for a long time or getting all the air out of your lungs when you exhale; only your most forceful rate of exhalation will register on the meter. If you cough or sneeze into the device, you will have to do it over again, as these will give you false readings that are higher than your actual peak exhalation.  Don't forget to write down the meter reading! Each time you take a reading using your peak flow meter, you should do the test three times in order to eliminate the possibility that your reading was affected by user or device error. The highest of the three readings is the one you should keep for your records. This is also why it is important to write down each of your test readings as you go.  Do not average your readings; you need to keep a record of your peak flow rate, which means you need to get the highest reading possible. If you don't have enough energy or are out of breath after the first test, make a note of this for your records and stick with your first test reading.

article: Plug the power washer in, connect it to a water source, and turn on the machine using the switch. Hold the end of the power washer 3–4 inches (7.6–10.2 cm) from the surface of the concrete and pull the trigger to shoot out water. Use back and forth strokes to clean all of the concrete completely. Focus on areas where concrete is loose or deteriorating.  Look for a power washer with a fan tip that reaches 3500 PSI to clean your concrete slabs. If you don’t have access to a power washer, you can get an attachment for your garden hose. Cleaning your concrete makes the resurfacer adhere better. Give the concrete 1-2 hours to dry after power washing it. When the surface of the concrete is dry to the touch, you can move on. Once the concrete is dry again, sweep the rest of the dust and residue off with a push broom. Work in small areas at a time to clean off the area entirely before moving on. Resurface your concrete on the same day you clean it, or else dirt and dust will start to form again. Remove the backing from peel-and-stick foam weather stripping. Push the weather stripping into the cracks between your concrete slabs so the resurfacer doesn’t fill them in.  Weather stripping can be purchased at your local hardware store. The expansion joints between slabs cannot be filled since they allow the slabs to shift naturally without cracking.

Offer your professional services for free. Drive a stranger home. Host a music festival and donate the proceeds to charity. Make a charitable donation."
article:
If it starts raining and you see someone stuck beneath the eaves of a shop because they were not expecting the storm, duck inside a convenience store and purchase an umbrella for them, if possible (and one for you, if necessary).  Give them the umbrella so they can go on their way. When your birthday or holidays draw near, your friends and family might start asking you what you want.  Ask them to make a charitable contribution to an organization of their choice (or of your choice) instead of getting you a gift. There are many ways to become a mentor.  For instance, if you’re a strong reader and writer, you could help out a young person who you know needs help writing an essay for school.  If you know a teen neighbor needs help finding a job but their parents are too busy, you could teach them how to browse classifieds, develop a resume, and dress properly for an interview. If you have a valuable skill set, you could put your abilities to work as a volunteer with an organization.  For instance, if you’re a lawyer, you might offer to help out at a nonprofit that needs help with a legal matter.  If you’re an electrician, you might be able to help fix electrical problems at your local homeless shelter or soup kitchen. If you see someone waiting at the bus stop or trying in vain to hail a taxi, pull over and offer them a ride to their destination.  The stranger is even more likely to appreciate and accept your offer if the weather is poor. Contact local music venues and ask if they would be willing to host an event for a charity.  Once you’ve secured a venue, contact some local musicians and ask if they would be interested in performing in a charity concert.  Once you have three or four bands or musicians available, advertise the event on social media and in local papers.  Donate the ticket sales to a worthy charity.  Encourage musicians and music venues to participate in your event by reminding them that while they won’t make money directly from ticket sales of the event, they will get positive exposure. Music venues, additionally, will earn money from the sale of food and drinks during the concert, while musicians can sell their records and other merchandise. Identify charities that match your interests, then research each to ensure they are legitimate.  Check each organization’s website for a clear mission statement and lists of its programs, board of directors, and accomplishments.  Find out how you can make a donation by checking the organization’s website.  The easiest way will probably be to use a credit card, PayPal, or another digital payment service. Many charities also accept checks or money orders. If you can’t find information online about how to make a donation, call the charity’s offices directly and inquire about how to do so. Use a third-party site like CharityWatch or GuideStar to identify charities and nonprofits that are legitimate.
