Captain America's Shield. Dr. The shield has great aerodynamic properties: it is able to slice through the air with minimal wind resistance and deflection of path. Its great overall resilience, combined with its natural concentric stiffness, enables it to rebound from objects with minimal loss of angular momentum.
Pneumonia is an infection of the lungs. People with pneumonia often complain about coughing, fever, shaking chills, and shortness of breath. 1  Your body's immune system usually keeps bacteria from infecting your lungs.2  In pneumonia, bacteria reproduce in your lungs, while your body tries to fight off the infection.f you inhale toxic materials, you can injure your lungs and cause chemical pneumonia. Fungus also can cause pneumonia. In certain areas of the United States, specific fungi are well known. Coccidioidomycosis causes a pneumonia called San Joaquin fever or  Valley fever  in the desert regions of California.
Bronchial pneumonia is triggered in people with immune defense system that is weak, and most often by a simple viral upper respiratory tract infection or a case of influenza. Bronchial pneumonia that is caused by a cold or flu is known as 'walking pneumonia'.If your immune system is already compromised, pneumonia can be life-threatening. Viruses or bacteria usually cause pneumonia, however, some types of fungi and parasites can also cause it.ronchial pneumonia happens when the pneumonia spreads to several patches in the lungs.
