In mathematics , the Bohr compactification of a topological group G is a compact Hausdorff space compact Hausdorff topological group H that may be canonical form canonically associated to G . Its importance lies in the reduction of the theory of uniformly almost periodic function s on G to the theory of continuous function s on H . The concept is named after Harald Bohr who pioneered the study of almost periodic function s, on the real line . Definitions and basic properties Given a topological group G , the Bohr compactification of G is a compact Hausdorff topological group Bohr G and a continuous homomorphism b G Bohr G which is universal property universal with respect to homomorphisms into compact Hausdorff groups this means that if K is another compact Hausdorff topological group and f G K is a continuous homomorphism, then there is a unique continuous homomorphism Bohr f Bohr G K such that f Bohr f b . Theorem . The Bohr compactification exists and is unique up to isomorphism. This is a direct application of the Tychonoff theorem . We will denote the Bohr compactification of G by Bohr G and the canonical map by math mathbf b G rightarrow mathbf Bohr G . math The correspondence G Bohr G defines a covariant functor on the category of topological groups and continuous homomorphisms. The Bohr compactification is intimately connected to the finite dimensional unitary representation theory of a topological group. The kernel algebra kernel of b consists exactly of those elements of G which cannot be separated from the identity of G by finite dimensional unitary representations.

lunar crater data latitude 12.8 N or S N longitude 86.4 E or W W diameter 71 km depth Unknown colong 87 eponym Niels Bohr Bohr is a moon lunar Impact crater crater that is located near the western moon lunar limb, in the area that is affected by libration s. It is attached to the southwestern rim of the larger, eroded Vasco da Gama crater Vasco da Gama formation, and to the southeast of the crater Einstein crater Einstein . The rim of Bohr is worn and eroded, and a pair of small, bowl shaped craters lies across the western rim. The rim to the northeast has been shored up by the adjacent Vasco da Gama, but the remainder forms an irregular ring of rugged ground. To the southwest of Bohr is a valley formation following a path in a north south direction. This long cleft is most likely associated with the formation of the Mare Orientale farther to the south.

The Bohr equation , named after named after Denmark Danish physician Christian Bohr 1855 1911 , describes the amount of Dead space physiology physiological dead space in a person s lungs. This is given as a ratio of dead space to tidal volume . It differs from Dead space physiology Anatomical dead space anatomical dead space as measured by Fowler s method as it includes Pulmonary alveolus alveolar dead space. Description The Bohr equation is used to quantify the ratio of physiological dead space to the total tidal volume, and gives an indication of the extent of wasted ventilation. It is stated as follows ref Respiratory Physiology The Essentials, J. West , 2005, 7th ed, Page 169 ref math frac mathbf V mathrm d mathbf V mathrm t frac mathrm P mathrm a mathrm CO mathrm 2 mathrm P mathrm e mathrm CO mathrm 2 mathrm P mathrm a mathrm CO mathrm 2 math Derivation Its derivation is based on the fact that only the ventilated gases involved in gas exchange math V a math will produce Carbon dioxide CO sub 2 sub . Because the Total tidal volume math V t math is made up of math V a V d math alveolar volume dead space volume , we can substitute math V a math for math V t V d math . Initially, Bohr tells us Vt Vd Va. The Bohr equation helps us find the amount of any expired gas, CO2 , N sub 2 sub , O sub 2 sub , etc. In this case we will focus on CO2 . Defining Fe as the fraction of expired CO2 and Fa as the fraction of expired alveolar CO2 , and Fd as fraction of expired dead space volume CO2 , we can say br Vt x Fe Vd x Fd Va x Fa . This merely means all the CO2 expired comes from two parts, the dead space volume and the alveolar volume. br If we suppose that Fd 0 since carbon dioxide concentration in air is normally negligible , then we can say that ref Davies, Andrew, and Carl Moores.
