Harvey Karman
Harvey Leroy Karman (April 26, 1924 – May 6, 2008) was an American psychologist and the inventor of the Karman cannula, a flexible suction cannula used for early-term abortions. Karman was born Harvey Walters in Clatskanie, Oregon. His father abandoned him when Harvey was young. He took the surname of one of his several stepfathers, William Karman. Conviction In 1955, Karman, who at the time was working towards his doctorate in psychology and who was not licensed to practice medicine, used a speculum and a nutcracker to perform an abortion on a woman in a California motel room, who subsequently died. He was convicted of providing abortion, which was illegal in California at the time. He served two-and-a-half years in state prison. "Super coils" Karman also developed the "super coil" abortion technique, which he believed would enable lay practitioners to perform second- trimester abortions with little training or equipment. The coils were inserted into the uterus, where they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

József Kármán
József Kármán (14 March 1769 in Losonc – 3 June 1795 in Losonc), sentimentalist Hungarian author, was born at Losonc (today Lučenec in Slovakia Slovakia (; sk, Slovensko ), officially the Slovak Republic ( sk, Slovenská republika, links=no ), is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the s ...) in 1769, the son of a Calvinist pastor. He was educated at Losonc and Pest (city), Pest, whence he migrated to Vienna. There he made the acquaintance of the beautiful and eccentric Countess Markovics, who was for a time his mistress, but she was not, as has often been supposed, the heroine of his famous novel ''Fanni hagyományai'' ("Fanny's testament"). Subsequently, he settled in Pest as a lawyer. His sensibility, social charm, liberal ideas (he was one of the earliest of the Hungarian people, Magyar freemasons) and personal beauty opened the doors of the best houses to him. ...

Theodore Von Kármán
Theodore von Kármán ( hu, ( szőllőskislaki) Kármán Tódor ; born Tivadar Mihály Kármán; 11 May 18816 May 1963) was a Hungarian-American mathematician, aerospace engineer, and physicist who was active primarily in the fields of aeronautics and astronautics. He was responsible for many key advances in aerodynamics, notably on supersonic and hypersonic airflow characterization. He is regarded as an outstanding aerodynamic theoretician of the 20th century. Early life Theodore von Kármán was born into a Jewish family in Budapest, Austria-Hungary, as Kármán Tódor, the son of Helen (Kohn, hu, Kohn Ilka) and Mór Kármán. One of his ancestors was Rabbi Judah Loew ben Bezalel. He studied engineering at the city's Royal Joseph Technical University, known today as Budapest University of Technology and Economics. After graduating in 1902 he moved to the German Empire and joined Ludwig Prandtl at the University of Göttingen, where he received his doctorate in 1908. He taug ...

Karman Cannula
The Karman cannula is a soft, flexible cannula (or curette) used in medical procedures that was popularized by Harvey Karman in the early 1970s. The flexibility of the Karman cannula was claimed to reduce the risk of perforating the uterus during vacuum aspiration. Both Karman's procedure, menstrual extraction, and his cannula were embraced by activists Carol Downer and Lorraine Rothman, who modified the technique in 1971 and promoted it. The "self-help" abortion movement envisioned by Downer and Rothman never entered the mainstream in the U.S. before or after ''Roe v. Wade''. Physicians sometimes use a Karman cannula in early induced surgical abortion, in treatment of incomplete abortion, and in endometrial biopsy. In 2010, a Sri Lankan physician named Geeth Silva was the first physician to use the Karman cannula in the removal of impacted faeces from a patient; this was done in Columbo at the Sri Jayawardenepura General Hospital.

Kármán–Howarth Equation
In isotropic turbulence the Kármán–Howarth equation (after Theodore von Kármán and Leslie Howarth 1938), which is derived from the Navier–Stokes equations, is used to describe the evolution of non-dimensional longitudinal autocorrelation. Mathematical description Consider a two-point velocity correlation tensor for homogeneous turbulence : R_(\mathbf,t) = \overline. For isotropic turbulence, this correlation tensor can be expressed in terms of two scalar functions, using the invariant theory of full rotation group, first derived by Howard P. Robertson in 1940, :R_(\mathbf,t) = u'^2 \left\, \quad f(r,t) = \frac, \quad g(r,t) = \frac where u' is the root mean square turbulent velocity and u_1,\ u_2, \ u_3 are turbulent velocity in all three directions. Here, f(r) is the longitudinal correlation and g(r) is the lateral correlation of velocity at two different points. From continuity equation, we have :\frac=0 \quad \Rightarrow \quad g(r,t) = f(r,t) + \frac \fracf(r,t) Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kármán Line
The Kármán line (or von Kármán line ) is an attempt to define a boundary between Earth's atmosphere and outer space, and offers a specific definition set by the Fédération aéronautique internationale (FAI), an international record-keeping body for aeronautics. Defining the edge of space is important for legal and regulatory purposes since aircraft and spacecraft fall under different jurisdictions and are subject to different treaties. International law does not define the edge of space, or the limit of national airspace. The FAI defines the Kármán line as space beginning above Earth's mean sea level. This number is well above the altitude reachable by a conventional airplane and is roughly where satellites, even on very eccentric trajectories, will decay before completing a single orbit. While experts disagree on exactly where the atmosphere ends and space begins, most regulatory agencies (including the United Nations) accept the FAI Kármán line definition or someth ...

Kármán Vortex Street
In fluid dynamics, a Kármán vortex street (or a von Kármán vortex street) is a repeating pattern of swirling vortices, caused by a process known as vortex shedding, which is responsible for the unsteady separation of flow of a fluid around blunt bodies. It is named after the engineer and fluid dynamicist Theodore von Kármán, and is responsible for such phenomena as the "singing" of suspended telephone or power lines and the vibration of a car antenna at certain speeds. Mathematical modeling of von Kármán vortex street can be performed using different techniques including but not limited to solving the full Navier-Stokes equations with k-epsilon, SST, k-omega and Reynolds stress, and large eddy simulation (LES) turbulence models, by numerically solving some dynamic equations such as the Ginzburg-Landau equation, or by use of a bicomplex variable. Analysis A vortex street will form only at a certain range of flow velocities, specified by a range of Reynolds numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karmann
Wilhelm Karmann GmbH, commonly known as simply Karmann, was a German automobile manufacturer and contract manufacturer based in Osnabrück. Founded by Wilhelm Karmann in 1901, the company specialized in a variety of automotive roles, including design, production and assembly of components for a wide variety of automobile manufacturers, including Chrysler, Porsche, Mercedes-Benz and Volkswagen Group. The company was broken up in 2010, after filing for bankruptcy the previous year. Its convertible roof components were purchased by Webasto, Magna Steyr, and Valmet Automotive— while the Osnabrück assembly plant, vehicle development, tools, and assembly systems were transferred to Volkswagen. History Karmann was established in 1901 when Wilhelm Karmann purchased Klages, a coachbuilder founded in 1874, and renamed the business. The company then grew together with the expanding automobile industry. Karmann became known for its work on convertibles, coupés, and other niche model ...
