Q: If you think your teacher treats you worse than other students, go to your teacher directly. There might be a simple miscommunication you can clear up, or an unhelpful behavior that one of you can change. Choose a time when neither of you is under pressure. Don't speak to him if there is a line of kids waiting to discuss their grade on a test, for example, or when the teacher is in a rush to prepare for a meeting. If you are too intimidated to speak to your teacher alone, see if the school guidance counselor will join the conversation. If your teacher is doing something that you know the school or your parents would not approve of, you may need to ask your parents to intervene. For example, your teacher punishes the entire class with weekend detention for something only a few students (not you!) are doing. Any time your teacher makes nasty comments to you or the class that involve race, gender, nationality, or anything of this nature. If you feel your teacher is truly out of hand, and not treating you fairly, you might try keeping a record of incidents as they happen. Write down any hurtful comments, along with the date, your side of the conversation. After you have a long list of complaints, you can go to a parent or the principal about it. It's natural to vent to your friends, and they will most likely agree with you. But if you stir things up, it is sure to get back to your teacher. This make things worse for you, and cause trouble for your friends, as well. Scowling, rolling your eyes, talking back, or walking off in the middle of a conversation will only make the situation worse a lot worse. And you don't want to give your teacher anything they can complain about to your parents or the principal. Teachers are people, too. Sometimes personalities simply clash with each other just as there are kids you get along with, and others you can't stand to be around. The best teachers are careful to treat all their students alike, but not all of them do. Be sure your parents are aware of the problem, in case your teacher complains to them about you. Be as polite as possible, and try to get through each class without incident. You probably won't have to deal with this teacher next year. If you're in high school, this is just one hour out of your day. Although it is extremely annoying to deal with an annoying teacher, don't let it take over your life. When you're not in their class, try not to let it get you down.
A: Talk to your teacher. Get your parents involved. Keep a complaint log. Avoid starting a war. Be respectful. Accept that you won't get along with everyone. Keep things in perspective.

Q: Place the middle of the pashmina horizontally flat across the top of your head. Either knot the tails at the nape of your neck or just make an "x" with them. Either way, the tails of the pashmina should drape over your shoulders and fall forward onto your chest. If you'd like to go incognito or vintage, add a pair of sunglasses to your outfit. Fold your scarf up so that the fabric is a bit thicker and not very wide. Wrap the scarf along your hairline above your forehead and let the ends hang down your back. Then tie the scarf in a double-knot at the nape of your neck so that it will not slide off. Leave the ends trailing down your back, or sweep them forward over your shoulder to hang down your front. Open your scarf so that it is unfolded completely and the entire scarf is exposed. Wrap it around your back and around your shoulders, so that the ends hang loosely between your arms and your sides. If you want to secure the scarf, tuck the ends back behind you under your armpits and tie it in a double knot or pin it together in the front with a stylish broach. Unfold your pashmina entirely and place the open scarf around your shoulders, keeping one side longer than the other. Drape the longer side across the opposite shoulder so that it will be securely positioned.
A: Use your pashmina to create a loose head scarf. Tie your hair back with your pashmina. Wear your pashmina as a shawl. Make your pashmina into a chic cape.

Q: If your family doctor thinks you have a restrictive lung disease, they will refer you to a respiratory (lung) specialist, also known as a pulmonologist, for further testing. The pulmonologist may conduct a helium dilution test. This inert gas dilution method uses helium to directly identify your residual lung volume. To start the test, you'll exhale normally and then be connected to a closed system containing known volumes of helium and oxygen. Once connected, you breathe in the helium and the amount exhaled is measured. The difference between the two volumes of helium is a pretty accurate estimate of your residual lung volume. Helium is an inert, colorless, odorless, tasteless gas and is non-toxic to your lungs, so there are no health concerns related to this exam. This technique may underestimate residual lung volume because it measures only the lung volume that communicates with the airways. This can be problematic for patients with severe airflow limitation. You will also need a referral to a pulmonologist to have this test done, which measures the air remaining in your conducting airways. To start the test, you'll exhale normally and then be connected to a spirometer that contains 100% oxygen. You'll then breath in deeply and exhale as strongly as you can, and the spirometer will measure the amount of exhaled nitrogen compared to the entire volume of exhaled air. The halfway point of the percentage of exhaled nitrogen allows the doctor to figure out the amount of gas you expelled, which is equal to the residual lung volume. Recall that the air we normally breathe in is about 21% oxygen and 78% nitrogen. This test forces you to breathe 100% oxygen and then measures the amount of nitrogen exhaled, a predetermined percentage of which represents residual lung volume. Like the helium dilution technique, nitrogen washout can also underestimate residual lung volume in patients with severely restricted airflow. This very accurate method for measuring residual lung volume uses a plethysmograph, which is an enclosed instrument (a small chamber you sit in) used for recording an organ's volume change. Once inside an airtight plethysmograph it sort of looks like a small phone booth you'll be asked to normally exhale, then inhale against a closed mouthpiece. As your chest wall expands, the pressure within the plethysmograph rises, which is calculated. Then you'll exhale as hard as you can out through the mouthpiece. The difference in pressures represent your residual lung volume. Body plethysmography uses Boyle's gas law (pressure and volume of a gas have an inverse relationship when temperature is constant) to determine residual lung volume and other lung volumes. Body plethysmography is considered more accurate than gas dilution methods for calculating lung volumes, particularly if the lung is obstructed.
A:
Get a referral to a medical specialist who can conduct a helium dilution test. Consider the nitrogen washout technique. Have a body plethysmography done for best accuracy.
