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.

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.

Image Bendradius.svg thumb 350px Bend radius Bend radius , which is measured to the inside curvature , is the minimum radius one can bend a pipe material pipe , tubing material tube , Sheet metal sheet , cable or hose tubing hose without kinking it, damaging it, or shortening its life. The smaller the bend radius, the greater is the material flexibility as the radius of curvature applications radius of curvature decreases , the curvature increases . The diagram below illustrates a cable with a seven centimeter bend radius. The minimum bend radius is the radius below which an object such as a cable should not be bent. Fiber optics The minimum bend radius is of particular importance in the handling of fiber optic cable s, which are often used in telecommunications . The minimum bending radius will vary with different cable designs. The manufacturer should specify the minimum radius to which the cable may safely be bent during installation, and for the long term. The former is somewhat shorter than the latter. The minimum bend radius is in general also a function of tensile stresses, e.g., during installation, while being bent around a sheave while the fiber or cable is under tension. If no minimum bend radius is specified, one is usually safe in assuming a minimum long term low stress radius not less than 15 times the cable diameter. Beside mechanical destruction, another reason why one should avoid excessive bending of fiber optic cables is to minimize microbending and macrobending losses. Microbending causes light attenuation induced by deformation of the fiber while macrobending causes the leakage of light through the fiber cladding and this is more likely to happen where the fiber is excessively bent. Microbending is explained better at photonics.com http www.photonics.com directory dictionary lookup.asp?url lookup&entrynum 3235&letter m Other applications Strain gauge s also have a minimum bending radius. This radius is the radius below which the strain gauge will malfunction ... more details
