| OB/GYN |
Obstetrics and gynaecology (often abbreviated OB/GYN in the U.S. and O&G elsewhere) form a single medical specialty and have a combined postgraduate training program. This is quite arduous: (in Australia, for example, it is among the longest, six years, matched only by neurosurgery). Some generalists can work as obstetricians, mainly in rural areas. All gynaecologists, therefore, are trained obstetricians, and vice versa. ...

An anaerobic organism or anaerobe is any organism that does not require oxygen for growth. Obligate anaerobes will die when exposed to atmospheric levels of oxygen, while facultative anaerobes can use oxygen when it is present. Aerotolerant organisms do not require oxygen, but are not affected by exposure to air. ...

| object |
In strictly mathematical branches of computer science the term object is used in a purely mathematical sense to refer to any "thing". While this interpretation is useful in the discussion of abstract theory, it is not concrete enough to serve as a primitive in the discussion of more concrete branches (such as programming) that are closer to actual computation and information processing. ...
