An aqueous solution is a solution in which the solvent is water. It is usually shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl â (aq).
Individual ergonomic assessment. An ergonomic evaluation is a formal, structured process that assesses many physical and cognitive parameters of the worker, the workspace, and the job characteristics to determine if the job fits the worker and to identify ALL risk factors for repetitive strain injury (RSI) .
Something that is designed to work smoothly with the human body is designed to be ergonomic. If your fingers ache after using the computer, you may need an ergonomic keyboard. Or you could play fewer video games. The study of ergonomics looks at making man and machine work together most efficiently, especially in the workplace. An ergonomic design is one that offers a worker comfort while using it.
