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) .
It is one of the most fundamental engineering tools. Re-evaluation should be a continual process with many parallel loops. Re-evaluate means observing outputs and using this information to modify the system, the inputs, the product or the process. Figure 1 summarizes the Systems Engineering Process.
