|When an object breaks into two parts or pieces or gets separated in two different parts due to stress then that is the situation which we call a fracture. There are two common types of fracture; they are brittle fracture and ductile fracture. It can be a bone fracture, ligament fracture, etc. It can be diagnosed by x ray or other imaging techniques.
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.
