Meningitis is a disease caused by the inflammation of the protective membranes covering the brain and the spinal cord. While most people with meningitis recover, it can cause serious complications, such as brain damage, hearing loss or learning disabilities. A vaccination is the most effective way to protect yourself against certain types of meningitis.
Primary & Secondary pollutant. Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.
The air temperature produced by your system depends on the temperature of the air going into it. Generally, the air produced should be 15Â°-20Â° below what enters the system. So if the entering return air is 80Â°, the exiting supply air should be about 60Â°-65Â°.
