Abbe (crater)
Abbe is a lunar impact crater that is located in the southern hemisphere on the far side of the Moon. It is located just to the south of the crater Hess, and lies to the east of the large walled basin Poincaré. It is named after the German physicist Ernst Abbe Ernst Karl Abbe HonFRMS (23 January 1840 – 14 January 1905) was a German physicist, optical scientist, entrepreneur, and social reformer. Together with Otto Schott and Carl Zeiss, he developed numerous optical instruments. He was also a co-ow .... The outer wall of Abbe is somewhat eroded, with small craters lying across the northwest and southwest rim crests. The interior floor is relatively smooth, with a few tiny craterlets marking the surface. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Abbe.

Lake Abbe
Lake Abbe, also known as Lake Abhe Bad, is a salt lake, lying on the Ethiopia-Djibouti border. It is one of a chain of six connected lakes, which also includes (from north to south) lakes Gargori, Laitali, Gummare, Bario and Afambo. The lake is the ultimate destination of the Awash River, which is at the center of the Afar Depression. Lake Abbe is considered one of the most inaccessible areas of the earth. The water itself is known for its flamingos. The scenery is unique. Overview Lake Abbe is the ultimate destination of the waters of the Awash River. It lies at the Afar Triple Junction, the central meeting place for the three pieces of the Earth's crust, a defining feature of the Afar Depression. Here three pieces of Earth's crust are each pulling away from that central point, though not all at the same speed. On the northwest shore rises Mount Dama Ali (1069 m), a dormant volcano, while along the southwestern and southern shores extend vast salt flats, 10 km in width ...

Abbey Falls
Abbey Falls (also spelled Abbi Falls and Abbe Falls) ( kn, ಅಬ್ಬೆ ಜಲಪಾತ ) is a waterfall in Kodagu, in the Western Ghats of Karnataka, India. It is located 8 km from the Madikeri, 122 km from Mysore, 144 km from Mangalore and 268 km from Bangalore. The waterfall is on the early reaches of the river Kaveri, located between private coffee plantations with stocky coffee bushes and spice estates and trees entwined with pepper vines. There is a hanging bridge Hanging Bridge is a medieval bridge spanning the Hanging Ditch, which connected the rivers Irk and Irwell in Manchester, England. The first reference to the bridge was in 1343, when it was called Hengand Brigge, but the present structure was ... constructed just opposite the falls. Flow is much higher during the monsoon season. The falls was earlier called Jessi Falls, named after a British officer's wife. However, the place was a thick jungle back then. Years later, the waterfa ...

Abbé
''Abbé'' (from Latin ''abbas'', in turn from Greek , ''abbas'', from Aramaic ''abba'', a title of honour, literally meaning "the father, my father", emphatic state of ''abh'', "father") is the French word for an abbot. It is the title for lower-ranking Catholic clergy in France. History A concordat between Pope Leo X and King Francis I of France (1516) cites III under Kinds of Abbot gave the kings of France the right to nominate 255 commendatory abbots () for almost all French abbeys, who received income from a monastery without needing to render service, creating, in essence, a sinecure. From the mid-16th century, the title of ''abbé'' has been used in France for all young clergy, with or without consecration. Their clothes consisted of black or dark violet robes with a small collar, and they were tonsured. Since such ''abbés'' only rarely commanded an abbey, they often worked in upper-class families as tutors, spiritual directors, etc.; some (such as Gabriel Bonnot de M ...

Abbe Condenser
A condenser is an optical lens which renders a divergent beam from a point source into a parallel or converging beam to illuminate an object. Condensers are an essential part of any imaging device, such as microscopes, enlargers, slide projectors, and telescopes. The concept is applicable to all kinds of radiation undergoing optical transformation, such as electrons in electron microscopy, neutron radiation and synchrotron radiation optics. Microscope condenser Condensers are located above the light source and under the sample in an upright microscope, and above the stage and below the light source in an inverted microscope. They act to gather light from the microscope's light source and concentrate it into a cone of light that illuminates the specimen. The aperture and angle of the light cone must be adjusted (via the size of the diaphragm) for each different objective lens with different numerical apertures. Condensers typically consist of a variable-aperture diaphragm and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lip Reconstruction
Lip reconstruction may be required after trauma or surgical excision. The lips are considered the beginning of the oral cavity and are the most common site of oral cancer. Any reconstruction of the lips must include both functional and cosmetic considerations. The lips are necessary for speech, facial expression, and eating. Because of their prominent location on the face, even small abnormalities can be apparent. Relevant anatomy Superficial The upper and lower lips include the vermilion border. This is the juncture between the lighter skin and the redder tissue (vermilion) that we commonly call the lip. This tissue is red because the skin is thin and underlain by large numbers of capillaries. The vermilion is different both from the oral mucosa and from regular skin, as it includes a cornified stratum corneum and lacks salivary glands, unlike the oral mucosa, but is thinner and more vascularised than regular skin, and lacks both hair follicles and sweat glands.

Abbe Number
In optics and lens design, the Abbe number, also known as the V-number or constringence of a transparent material, is an approximate measure of the material's dispersion (change of refractive index versus wavelength), with high values of ''V'' indicating low dispersion. It is named after Ernst Abbe (1840–1905), the German physicist who defined it. The term V-number should not be confused with the normalized frequency in fibers. The Abbe number, ''Vd'', of a material is defined as :V_D = \frac, where ''n''C, ''n''d and ''n''F are the refractive indices of the material at the wavelengths of the Fraunhofer ''C'', ''d'', and ''F'' spectral lines (656.3 nm, 587.56 nm, and 486.1 nm respectively). This formulation only applies to the visible spectrum. Outside this range requires the use of different spectral lines. For non-visible spectral lines the term V-number is more commonly used. The more general formulation defined as, :V = \frac, where ''n''short, ''n''cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbe Prism
In optics, an Abbe prism, named for its inventor, the German physicist Ernst Abbe, is a type of ''constant deviation dispersive prism'' similar to a Pellin–Broca prism. Structure The prism consists of a block of glass forming a right prism with 30°–60°–90° triangular faces. When in use, a beam of light enters face AB, is refracted and undergoes total internal reflection from face BC, and is refracted again on exiting face AC. The prism is designed such that one particular wavelength of the light exits the prism at a deviation angle (relative to the light's original path) of exactly 60°. This is the minimum possible deviation of the prism, all other wavelengths being deviated by greater angles. By rotating the prism (in the plane of the diagram) around any point O on the face AB, the wavelength which is deviated by 60° can be selected. The dispersive Abbe prism should not be confused with the non-dispersive Porro–Abbe or Abbe–Koenig prism An Abbe–Koenig prism ...

Abbe Refractometer
An Abbe refractometer is a bench-top device for the high-precision measurement of an index of refraction. Details Ernst Abbe (1840–1905), working for Carl Zeiss AG in Jena, Germany in the late 19th century, was the first to develop a laboratory refractometer. These first instruments had built-in thermometers and required circulating water to control instrument and fluid temperatures. They also had adjustments for eliminating the effects of dispersion and analog scales from which the readings were taken. In the Abbe refractometer the liquid sample is sandwiched into a thin layer between an illuminating prism and a refracting prism. The refracting prism is made of a glass with a high refractive index (e.g., 1.75) and the refractometer is designed to be used with samples having a refractive index smaller than that of the refracting prism. A light source is projected through the illuminating prism, the bottom surface of which is ground (i.e., roughened like a ground-glass jo ...

Abbe Sine Condition
The Abbe sine condition is a condition that must be fulfilled by a lens or other optical system in order for it to produce sharp images of off-axis as well as on-axis objects. It was formulated by Ernst Abbe in the context of microscopes. The Abbe sine condition says that the sine of the object-space angle \alpha_o should be proportional to the sine of the image space angle \alpha_i Furthermore, the ratio equals the magnification of the system. In mathematical terms this is: :\frac = \frac = , M, where the variables (\alpha_o, \beta_o) are the angles (relative to the optic axis) of any two rays as they leave the object, and (\alpha_i, \beta_i) are the angles of the same rays where they reach the image plane (say, the film plane of a camera). For example, (\alpha_o, \alpha_i) might represent a paraxial ray (i.e., a ray nearly parallel with the optic axis), and (\beta_o, \beta_i) might represent a marginal ray (i.e., a ray with the largest angle admitted by the system apert ...

Abbe Creek School
The historic Abbe Creek School is a one-room schoolhouse museum located one mile west of Mt. Vernon, Iowa, on E48. It is believed to be the oldest standing one room brick schoolhouse in Iowa.Booklet prepared by Linn County Historical Museum The school is located on land claimed by William Abbe, the first white settler in Linn County, Iowa. History Community established Abbe Creek School was first organized in 1844 by pioneer homesteaders: Alison I. Willets; Jesse Holman; and Peter, Henry and Conrad Kepler. They engaged a carpenter named Lichtenbarger to build the first log school. The school was first called Sumner School but later it came to be known affectionately as “Little Brick.” Locally, it was called Kepler most likely because many Kepler family members attended. Construction Records in the Linn County assessor's office indicate that the present school house was built in 1856 of soft brick thought to have been manufactured locally at Port Stottler brickyard.
