Rheumatology is a branch of science that deals with the causes, diagnosis, treatment and scientific research on it. This includes rheumatic diseases that occur in joints, soft tissues, connective tissues, etc. These diseases mainly occur due to the denaturation of cartilage protein that is present between bones. Cartilage acts as a cushion between the bones and help to reduce friction between the two. Rheumatic diseases are seen to occur more frequently in women than men with ageing. Women acquire them after the age of 55 while in the case of men, these occur after an age of 45. With ageing, there is deposition of water in the cartilage protein that in turn destructs it.
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.
