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) .
At its simplest definition ergonomicsâ, it literally means the science of work. So ergonomists, i.e. the practitioners of ergonomics, study work, how work is done and how to work better. It is the attempt to make work better that ergonomics becomes so useful. And that is also where making things comfortable and efficient comes into play. Ergonomics is commonly thought of in terms of products.
