Gas and Chemical Exposure. NOTE: This is the Consumer Version. Symptoms depend on which gas or chemical is inhaled and how deeply and for how long it was inhaled. Symptoms may include irritation of the eyes or nose, cough, blood in the sputum, and shortness of breath. Chest x-rays, computed tomography, and breathing tests are used to determine how much lung damage has occurred.
Scope refers to the visibility of variables and methods in one part of a program to another part of that program. The importance and meaning of scope varies between languages, but there are two general scope concepts many languages have in common: local and global scope.
Scope can be defined as the range, detail, or a boundary of a term it is attached to. If it is used with the term product it means the details of the product, and if it is attached to project then it means the details of the project.
