Aerodynamics first: The altitude factor of $c_l \cdot Ma^2$ tells you how much lift can be produced at a given flight Mach number, and the wing loading then gives you the minimum density for sustained flight. 0.4 is a good value for $c_l \cdot Ma^2$, and 30 kg/m$^2$ is a feasible wing loading for flight at 30 km.
Get worse with activity and improve with rest. Myasthenia gravis (MG) can affect any of the muscles that you control voluntarily. It can affect muscles of the face, hands, eyes, arms and legs and those muscles involved in chewing, swallowing and talking. Muscles that control breathing and neck movement also can be affected.
Use your hands â and this story â to learn what your hands may be telling you about your health. And be sure to discuss any concerns you have with your doctor or health professional. Symptoms: Bony outgrowths on the finger joints, which can interfere with hand function and cause fingers to look deformed. What it may mean: Nodules on the joint closest to the fingertip, known as Heberdenâs nodes, or the middle joint, known as Bouchardâs nodes, are characteristic of osteoarthritis, or OA.
