A Diffusion limited enzyme is an enzyme which catalyses a reaction so efficiently that the rate limiting step is that of substrate diffusion into the active site, or product diffusion out.
 This is also known as kinetic perfection or catalytic perfection.
 Since the rate of catalysis of such enzymes is set by the diffusion-controlled reaction, it therefore represents an intrinsic, physical constraint on evolution (a maximum peak height in the fitness landscape).
 Diffusion limited perfect enzymes are very rare.
 Most enzymes catalyse their reactions to a rate that is 1,000-10,000 times slower than this limit.
 This is due to both the chemical limitations of difficult reactions, and the evolutionary limitations that such high reaction rates do not confer any extra fitness.
"Shaka Beach: Laka Laka La" (Stylized as "シャカビーチ〜Laka Laka La〜") is the 8th single by the Japanese band Uverworld and was released on August 8, 2007 in CD and CD+DVD format.
 The song uses Spanish guitar influences.
 In the promotional video, people are seen doing the mambo.
The Mischievous Boy (Uzbek: "Shum bola, Шум бола" ; Russian: Озорник , "Ozornik " ) is a 1977 Uzbek adventure film based on an eponymous story by Gʻafur Gʻulom.
 The film was directed by Damir Salimov and the screenplay was written by Shuhrat Abbosov and Aleksandr Naumov (II).
 "Shum bola" is one of the most popular Uzbek films and has gained considerable acclaim both from Uzbek and foreign film critics.
 The film stars Abduraim Abduvahobov as Qoravoy, a ten-year-old boy whose restless nature leads him to deal with different people and life situations.
The archaeological site of Shum Laka is the most prominent rockshelter site in the Grasslands region of the Laka Valley, northwest Cameroon.
 Occupations at this rockshelter date to the Later Stone Age.
 This region is important to investigations of the development and subsequent diffusion of the Bantu culture.
 The site of Shum Laka is located approximately 15 kilometers from the town of Bamenda, and it resides on the inner wall of the Bafochu Mbu caldera.
 The deposits at Shum Laka include each phase of cultural development in the Grasslands.
Turbulent diffusion is the transport of mass, heat, or momentum within a system due to random and chaotic time dependent motions.
 It occurs when turbulent fluid systems reach critical conditions in response to shear flow, which results from a combination of steep concentration gradients, density gradients, and high velocities.
 It occurs much more rapidly than molecular diffusion and is therefore extremely important for problems concerning mixing and transport in systems dealing with combustion, contaminants, dissolved oxygen, and solutions in industry.
 In these fields, turbulent diffusion acts as an excellent process for quickly reducing the concentrations of a species in a fluid or environment, in cases where this is needed for rapid mixing during processing, or rapid pollutant or contaminant reduction for safety.
In image processing and computer vision, anisotropic diffusion, also called Perona–Malik diffusion, is a technique aiming at reducing image noise without removing significant parts of the image content, typically edges, lines or other details that are important for the interpretation of the image.
 Anisotropic diffusion resembles the process that creates a scale space, where an image generates a parameterized family of successively more and more blurred images based on a diffusion process.
 Each of the resulting images in this family are given as a convolution between the image and a 2D isotropic Gaussian filter, where the width of the filter increases with the parameter.
 This diffusion process is a "linear" and "space-invariant" transformation of the original image.
 Anisotropic diffusion is a generalization of this diffusion process: it produces a family of parameterized images, but each resulting image is a combination between the original image and a filter that depends on the local content of the original image.
 As a consequence, anisotropic diffusion is a "non-linear" and "space-variant" transformation of the original image.
K-25 was the codename given by the Manhattan Project during World War II for the project to produce enriched uranium for atomic bombs using the gaseous diffusion method.
 Originally the codename for the product, over time it came to refer to the project, the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site.
 When it was built in 1944, the four-story K-25 gaseous diffusion plant was the world's largest building, with over 1640000 sqft of floor space and a volume of 97500000 cuft .
The plasma diffusion across the magnetic field is an important topic in magnetic confinement of fusion plasma.
 It is especially concerning how the plasma transport is reduced by the strength of the external magnetic field.
 The classical diffusion gives the 1/B scaling, while the Bohm diffusion, borne out of experimental observations from the early confinement machines, was conjectured to follow the 1/B scaling.
 The Hsu diffusion predicts the 1/B scaling, that is presumably the best confinement scenario in magnetized plasma.
Bantu peoples is used as a general label for the 300–600 ethnic groups in Africa who speak Bantu languages.
 They inhabit a geographical area stretching east and southward from Central Africa across the African Great Lakes region down to Southern Africa.
 Bantu is a major branch of the Niger–Congo language family spoken by most populations in Africa.
 There are about 650 Bantu languages by the criterion of mutual intelligibility, though the distinction between language and dialect is often unclear, and "Ethnologue" counts 535 languages.
The Continental Society for the Diffusion of Religious Knowledge over the Continent of Europe (or simply Continental Society) was an evangelical Christian missionary society founded in London in 1819 for the propagation of the evangelical faith on the continent of Europe and existing as a separate entity until 1840 (see below).
