Most of the blood transfusion services are confined to hospitals, with no functional separation of the processes into production and utilization while majority of blood donations are offered by replacement blood donors. Donating blood may not only benefit the person who received the blood cells but may also improve the health of the donor. After donating blood, the count of blood cells decreases in our body, which stimulates the bone marrow to produce new red blood cells in order to replenish the loss. So, it stimulates the production of new blood cells and refreshes the system.
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.
