|Cyclical neutropenia is also known as cyclic neutropenia, a form of neutropenia which is a granulocyte disorder characterized by an abnormally low number of neutrophils. This tends to occur for every three weeks and lasts from three to six days due to changing rates of cell production by the bone marrow. Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
