Mean anomaly, a measure of time in the study of orbital dynamics Pioneer anomaly , the observed deviation of the trajectories of some uncrewed space probes, and especially Pioneer 10 and Pioneer 11 South Atlantic Anomaly , an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface
Gravity anomaly, difference between the observed gravity and a value predicted from a model Bouguer anomaly, anomaly in gravimetry; Free-air anomaly, gravity anomaly that has been computed for latitude and corrected for elevation of the station; Iridium anomaly, an unusual abundance of what is normally a very rare element in the Earth's crust
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
An orbiting body's mean longitude is calculated L = Ω + ω + M, where Ω is the longitude of the ascending node, ω is the argument of the pericenter and M is the mean anomaly, the body's angular distance from the pericenter as if it moved with constant speed rather than with the variable speed of an elliptical orbit.
Define ℓ as the mean longitude, the angular distance of the body from the same reference direction, assuming it moves with uniform angular motion as with the mean anomaly. Thus mean anomaly is also [6] = . Mean angular motion can also be expressed, = , where μ is the gravitational parameter, which varies with the masses of the objects, and a ...
A vascular anomaly is any of a range of lesions from a simple birthmark to a large tumor that may be disfiguring. They are caused by a disorder of the vascular system. [1] A vascular anomaly is a localized defect in blood vessels or lymph vessels. These defects are characterized by an increased number of vessels, and vessels that are both ...
A karyotype of an individual with trisomy 21, showing three copies of chromosome 21.. An abnormal number of chromosomes is known as aneuploidy, and occurs when an individual is either missing a chromosome from a pair (resulting in monosomy) or has more than two chromosomes of a pair (trisomy, tetrasomy, etc.).
Anatomical terms are not included here and appear in sub-categories of the main Anatomy category. Initially, some alignment between this category and the article Glossary of biology was considered, but the inclusion criteria for the Glossary is substantially broader and encompasses terminology, concepts, objects and processes.
