Fetus is the developing stage of the mammal after the embryonic stage and before the completion the gestation period.In humans it starts from the 11th week of the gestation period. The fetus develops into complete organism in the gestation period. The fetus is connected to the maternal body through the umbilical cord, which is the only passage or source of nutrition to the fetus. The characterization of the fetus is done by the presence of body parts which may not be functional or fully develobved but at their anatomical positions.
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.
