What Does High Hemoglobin Mean? High hemoglobin levels mean that measured hemoglobin levels are above the upper limits of normal for the age and sex of the person (see above normal values). For example, a 19 year old that has a detected hemoglobin level of above 17.7 g/dl would have a high hemoglobin level.
Some chemical engineers specialize in a particular process, such as oxidation (a reaction of oxygen with chemicals to make other chemicals) or polymerization (making plastics and resins).
Materials engineers typically do the following: 1  Plan and evaluate new projects, consulting with other engineers and managers as necessary. 2  Prepare proposals and budgets, analyze labor costs, write reports, and perform other managerial tasks. 3  Supervise the work of technologists, technicians, and other engineers and scientists.
