Since arch support is the best strategy for avoiding fallen arches, consider getting custom-made orthotics for your shoes. Orthotics are semi-rigid shoe inserts that not only support the arch of your foot, but they also combat over-pronation and promote better biomechanics while standing, walking and running. By providing cushioning and some shock absorption, orthotics also help to reduce the risk of problems developing in your ankles, knees, hips and low back. It's important to realize that foot orthotics don't reverse any structural deformities of the foot nor can they reconstruct an arch by wearing them over time, but they are a good preventative strategy for avoiding fallen arches. A variety of different healthcare professionals make custom orthotics, but they are not always covered by health insurance, so check your policy. Wearing orthotics often requires taking the shoes original insoles out in order to make enough room for your feet. Podiatrists are foot specialist who are familiar with all conditions and diseases of the feet, including fallen arches. Podiatrists can examine your foot and try to determine the risk factors that contributed to your flat feet. They will also look for any signs of bone trauma (fractures or dislocations), possibly with the help of x-rays. Depending on the severity of your symptoms and the cause of your fallen arches, the foot doctor may recommend basic home care (rest, salt baths, cold therapy, anti-inflammatory medications), orthotic therapy, casting or bracing the foot, or some form of surgery for the tendons of the feet. X-rays are ideal for seeing bones, but they are not diagnostic for soft tissue problems affecting tendons and ligaments. Podiatrists are trained for relatively minor operations of the feet, but more complex surgeries are usually reserved for orthopedic surgeons. If you're particularly concerned about developing fallen arches, then get a referral to a physical therapist and discuss how rehabilitation might help prevent them. A physical therapist can show you specific and tailored stretches and strengthening exercises for your feet, Achilles tendons and calf muscles that can help prevent fallen arches and other common foot problems. Physiotherapy is usually a longer-term commitment for rehabilitating most musculoskeletal issues, so plan on two to three times per week for four to eight weeks as a general guideline. Make sure that you do the exercises at home that your physical therapist teaches you, not just during your sessions together. This is the best way to see improvement. A good Achilles tendon stretch involves leaning against a wall with one leg at a time outstretched behind you in a lunge-like position. Make sure you keep the outstretched foot flat on the floor to feel a stretch in the tendon that connects your calf muscle to your heel. Hold for about 30 seconds and repeat five to 10 times daily. Physical therapists can tape your foot with sturdy medical-grade tape, which essentially provides a temporary artificial arch to help relieve symptoms. Physical therapists can also treat plantar fasciitis (a common complication of fallen arches) with therapeutic ultrasound, which helps to reduce inflammation and tenderness.

Summary: Get a pair of custom orthotics made. See a podiatrist. Consider physiotherapy treatments.

Once you've rinsed out the cornstarch and clarifying shampoo, shampoo your hair 1 more time. Rinse the hair with warm water to remove even more Vaseline. Keep rinsing until the water runs clear instead of cloudy or soapy. Because clarifying shampoos can strip your hair of its natural oils and dry it out, use a moisturizing conditioner. Follow the product instructions, then rinse the conditioner out with cool water to seal the hair cuticle. For example, some conditioners will direct you to massage it into wet hair for a few minutes and then let the conditioner rest in your hair for a few more minutes before you rinse it out. If your hair still feels greasy and you don't think you got all of the Vaseline out, wait 12 to 24 hours. Then apply more cornstarch to the greasy areas, wash your hair with clarifying shampoo, rinse it out, and condition your hair. Remember to blot your hair dry and let it finish drying on its own.

Summary: Shampoo and rinse your hair again. Apply a conditioner and rinse it out. Repeat the process in 12 to 24 hours if necessary.

Many people find that it is easier to play the trumpet while standing, but this is not always practical, especially when playing as part of an ensemble. Whether sitting or standing, be sure to keep your back straight. Slouching will affect your air flow, making it harder for you to play sustained notes and maintain a steady volume. Even when you're sitting or standing with your back straight, try to relax your shoulders. This will help you to take deeper breaths. It will also help prevent neck pain and tension if you're practicing or performing for long periods of time. You don't want the bell of the trumpet pointing at the floor, because then the sound won't travel as well. A downward slope of the trumpet will also restrict some of your airflow, which can affect the pitch and volume of your playing. The valve casing of your trumpet should always be vertical. Rotating the trumpet can put strain on your wrists and will prevent you from playing notes quickly and accurately. Don't tuck your elbows into your body, as this creates strain on your neck and shoulders and can restrict your airways. Instead, hold them slightly out from your sides at an angle that feels relaxed and natural. If you're holding the trumpet correctly, your forearms should come together at a right angle in front of your body.

Summary: Sit or stand up straight. Relax your shoulders. Point the trumpet straight ahead. Keep the trumpet straight up and down. Keep your elbows out from your body.

The atomic mass of hydrogen is 1.008 u. The atomic mass of carbon is 12.011 u. There are 4 hydrogen atoms in methane. Add together the weight of all the atoms in methane to find the molecular weight. 1.0084=4.032u{\displaystyle 1.008*4=4.032u}. 12.0111=12.011u{\displaystyle 12.011*1=12.011u} 12.011+4.032=16.043u{\displaystyle 12.011+4.032=16.043u} The atomic mass of carbon is 12.011 u. The atomic mass of hydrogen is 1.008 u. The atomic mass of oxygen is 15.999 There are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
