Rocket stove. A rocket stove is an efficient and hot burning[1] stove using small-diameter wood fuel.[2] Fuel is burned in a simple combustion chamber containing an insulated vertical chimney, which ensures almost complete combustion prior to the flames' reaching the cooking surface.
What Is Myasthenia Gravis? Myasthenia gravis is a chronic condition that causes muscles to tire and weaken easily. For example, if you have myasthenia gravis, you may notice that during a meal, your jaw muscles become tired and weak, interfering with your ability to chew food.
If you have myasthenia gravis, muscle strength will decrease predictably over the course of testing. You may be given certain medications -- edrophonium or neostigmine -- as part of a diagnostic exam. In a patient with myasthenia gravis, these drugs will significantly and noticeably improve muscle strength for a short time. This helps to further confirm the diagnosis.
