Pleural effusion may be caused by cancer, cancer treatment, or other conditions. A pleural effusion may be malignant (caused by cancer) or nonmalignant (caused by a condition that is not cancer). Malignant pleural effusion is a common problem for patients who have certain cancers. Lung cancer, breast cancer, lymphoma, and leukemia cause most malignant effusions.
Supercharged Engine. A (also known as a blower) is an air compressor used to force air into the combustion chamber(s) of an internal combustion engine at pressures higher than would otherwise be the case. Any device which does this is a .
For other uses, see Supercharge (disambiguation). In theoretical physics, a supercharge is a generator of supersymmetry transformations. It is an example of the general notion of a charge in physics. Supercharge, denoted by the symbol Q, is an operator which transforms bosons into fermions, and vice versa. Since the supercharge operator changes a particle with spin one-half to a particle with spin one or zero, the supercharge itself is a spinor that carries one half unit of spin.
