Bacterial growth refers to division of bacterium into two cells. That process of division is known as binary fission. This division is basically asexual. There are four phases in bacterial growth and they are lag phase, log phase, stationary phase and death phase. In some cases it can further be subdivided into lag phase, early log phase, exponential phase, early stationary phase, stationary phase, early death phase and death phase.
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.
