Biochemical engineering is a branch of chemical engineering which includes the construction and design of unit processes that involve biological molecules or organisms. It utilizes chemical engineering principles to design, develop, operate and use processes and products. It is useful in food, agriculture, waste treatment, biotechnological and pharmaceutical industries. It is involved in the culture of cells and their genetically engineered versions.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
