Osteitis Fibrosa Cystica
Osteitis fibrosa cystica ( ) is a skeletal disorder resulting in a loss of bone mass, a weakening of the bones as their calcified supporting structures are replaced with fibrous tissue ( peritrabecular fibrosis), and the formation of cyst-like brown tumors in and around the bone. Osteitis fibrosis cystica (OFC), also known as osteitis fibrosa, osteodystrophia fibrosa, and von Recklinghausen's disease of bone (not to be confused with von Recklinghausen's disease, neurofibromatosis type I), is caused by hyperparathyroidism, which is a surplus of parathyroid hormone from over-active parathyroid glands. This surplus stimulates the activity of osteoclasts, cells that break down bone, in a process known as osteoclastic bone resorption. The hyperparathyroidism can be triggered by a parathyroid adenoma, hereditary factors, parathyroid carcinoma, or renal osteodystrophy. Osteoclastic bone resorption releases minerals, including calcium, from the bone into the bloodstream, causing both elevat ...

SMS Language
Short Message Service (SMS) language, textism, or textese is the abbreviated language and slang commonly used in the late 1990s and early 2000s with mobile phone text messaging, and occasionally through Internet-based communication such as email and instant messaging. Features of early mobile phone messaging encouraged users to use abbreviations. 2G technology made text entry difficult, requiring multiple key presses on a small keypad to generate each letter, and messages were generally limited to 160 characters (or 1280 bits). Additionally, SMS language made text messages quicker to compose, while also avoiding additional charges from mobile network providers for lengthy messages exceeding 160 characters. History SMS language is similar to telegraphs' language where charges were by the word. It seeks to use the fewest letters to produce ultra-concise words and sentiments in dealing with the space, time, and cost constraints of text messaging. It follows from how early SMS pe ...

Fetal Head
The fetal head, from an obstetrical viewpoint, and in particular its size, is important because an essential feature of labor is the adaptation between the fetal head and the maternal bony pelvis. Only a comparatively small part of the head at term is represented by the face. The rest of the head is composed of the firm skull, which is made up of two frontal, two parietal, and two temporal bones, along with the upper portion of the occipital bone and the wings of the sphenoid. These bones are separated by membranous spaces, or sutures. The most important sutures are the frontal, between the two frontal bones; the sagittal, between the two parietal bones; the two coronal, between the frontal and parietal bones; and the two lambdoid, between the posterior margins of the parietal bones and upper margin of the occipital bone. Where several sutures meet, an irregular space forms, which is enclosed by a membrane and designated as a fontanel. The greater, or anterior fontanel, is a lozen ...

Open Financial Connectivity
Open Financial Exchange (OFX) is a data-stream format for exchanging financial information that evolved from Microsoft's Open Financial Connectivity (OFC) and Intuit's Open Exchange file formats. History Microsoft, Intuit and CheckFree announced the OFX standard on 16 January 1997. The first OFX specification, version 1.0, was released on 14 February 1997. The specification allows for bank- and application-specific extensions, although only a subset is necessary to describe a financial transaction. Versions 1.0 through 1.6 relied on SGML for data exchange, but later versions are XML based. According to the main OFX site, "The specification is freely licensed, allowing any software developer to design an interface that will be supported on the front-end." Support in various countries Many banks in the US let customers use personal financial management software to automatically download their bank statements in OFX format, but most Canadian, United Kingdom and Australian banks do ...

Oxy-fuel Welding And Cutting
Principle of burn cutting Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, bio diesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903. Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. A common propane/air flame burns at about , a propane/oxygen flame burns at about , an oxyhydrogen flame burns at and an acetylene/oxygen flame burns at about . During the early 20th century, before the development and availability of coated arc welding electrodes in the late 1920s that were capable of making sound welds in steel, oxy-acetylene welding was the only process capable of making welds of except ...

Oxygen-free Copper
Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below. Specification Oxygen-free copper is typically specified according to the ASTM/ UNS database. The UNS database includes many different compositions of high conductivity electrical copper. Of these, three are widely used and two are considered oxygen-free: * C10100 – also known as ''oxygen-free electronic'' (OFE). This is a 99.99% pure copper with 0.0005% oxygen content. It achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment. Silver (Ag) is considered an impurity in the OFE chemical specification. This is also the most expensive of the three grades listed here. * C10200 – also known as ''oxygen-free'' (OF). While OF is considered oxygen-free, its conductivity rating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orbitofrontal Cortex
The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of decision-making. In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47. The OFC is functionally related to the ventromedial prefrontal cortex.Phillips, LH., MacPherson, SE. & Della Sala, S. (2002). 'Age, cognition and emotion: the role of anatomical segregation in the frontal lobes: the role of anatomical segregation in the frontal lobes'. in J Grafman (ed.), Handbook of Neuropsychology: the frontal lobes. Elsevier Science, Amsterdam, pp. 73-98. Therefore, the region is distinguished due to the distinct neural connections and the distinct functions it performs.Barbas H, Ghashghaei H, Rempel-Clower N, Xiao D (2002) Anatomic basis of functional specialization in prefrontal cortices in primates.

Optical Fiber Cable
A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used. Different types of cable are used for different applications, for example, long distance telecommunication, or providing a high-speed data connection between different parts of a building. Design Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough ...

Open Fiber Control
In telecommunication, Open fiber control is a protocol to ensure that both ends of a fiber optic cable are connected before laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The fir ... signals are transmitted in order to protect people from eye damage. When a device is turned on, it sends out low powered light. If it does not receive light back, it assumes that the fiber is not connected. When it receives light, it assumes that both ends of the fiber are connected and it switches the laser to full power. If one of the devices stops receiving light, it will revert to the low power mode.Introduction to Storage Area Networks.
