Scoliosis is a condition where the shape of the spine is changed from straight to curved. The structure may be similar to S or A. It can be of two types, they are congenital and idiopathic. The congenital scoliosis is basically caused by abnormalities in vertebra that too from birth. The main reason of occurrence of idiopathic scoliosis is not known and is sub categorized according to the onset such as infantile, juvenile, adolescent or adult. People having reached skeletal maturity are less likely to have a worsening case. Some severe cases of scoliosis can lead to reducing lung capacity, putting pressure on the heart, and restricting physical activities.
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.
