Lake Abbe
Lake Abbe, also known as Lake Abhe Bad, is a salt lake (geography), 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 Lake Gargori, Gargori, Lake Laitali, Laitali, Lake Gummare, Gummare, Lake Bario, Bario and Lake Afambo, Afambo. The lake is the ultimate destination of the Awash River, which is at the center of the Afar Triangle. Lake Abbe is considered one of the most inaccessible areas of the earth. The water itself is known for its flamingos. 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbey Falls
Abbey Falls (also spelled Abbi Falls and Abbe Falls) 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 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 waterfall was discovered by Mr. Neravanda B. Nanaiah who bought the place from the government and converted it into a coffee and spice plantation, which still surrounds the waterfall today.

Abbe Condenser
A condenser is an optical lens that renders a divergent light beam from a point light source into a parallel or converging beam to illuminate an object to be imaged. 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 va ... [...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 Vd-number or constringence of a Transparency (optics), transparent material, is an approximate measure of the material's dispersion (optics), dispersion (change of refractive index versus wavelength), with high values of ''Vd'' indicating low dispersion. It is named after Ernst Abbe (1840–1905), the German physicist who defined it. The term Vd-number should not be confused with the Normalized frequency (fiber optics), normalized frequency in fibers. The Abbe number, V_\mathsf d\ , of a material is defined as : V_\mathsf d \equiv \frac, where n_\mathsf C, n_\mathsf d, and n_\mathsf F are the refractive indices of the material at the wavelengths of the Fraunhofer lines, Fraunhofer's C, d, and F spectral lines (656.3 nanometre, nm, 587.56 nm, and 486.1 nm respectively). This formulation only applies to the visible spectrum, human vision. Outside this range requires the use of different spectral lines. Fo ...

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 In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats. In other words, it is the distance between consecutive corresponding points of the same ''phase (waves ... 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 p ...

Abbe Refractometer
An Abbe refractometer is a bench-top device for the high-precision measurement of an Refractive index, 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 (optics), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abbe Sine Condition
In optics, 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_\mathrm should be proportional to the sine of the image space angle \alpha_\mathrm Furthermore, the ratio equals the magnification of the system multiplied by the ratio of refractive indices. In mathematical terms this is: \frac = \frac = \frac, M, where the variables (\alpha_\mathrm, \beta_\mathrm) are the angles (relative to the optic axis) of any two rays as they leave the object, and (\alpha_\mathrm, \beta_\mathrm) are the angles of the same rays where they reach the image plane (say, the film plane of a camera). For example, (\alpha_\mathrm, \alpha_\mathrm) might represent a paraxial ray (i.e., a ray nearly parallel with the optic axis), and (\beta_\m ...

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.
