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.
Arthritis can affect any of them causing a range of uncomfortable symptoms in your finger. The first symptoms you may notice are stiffness and a dull, achy pain in your finger. Swelling is another common symptom of finger arthritis.Sometimes, you may feel grinding or grating when you use a finger joint. As your arthritis progresses, you may notice bony nodules at the affected joints.f you have an autoimmune disease causing your finger arthritis, you may also need medicine to control your immune system. These treatments include disease-modifying anti-rheumatic drugs (DMARDs) to slow down joint destruction, andbiologic response modifiers (BRMs) to reduce inflammation and permanent joint damage.
