King Of The World (album)
''King of the World'' is the final album by French disco act Sheila and B. Devotion, released on June 27, 1980. The album which was both written and produced by Bernard Edwards and Nile Rodgers of American R&B band Chic includes the hit "Spacer" which reached No. 18 on the UK charts in early 1980 and was a Top 10 hit in most of Europe, selling more than 5 million copies worldwide. The album displays some elements unusual in Chic productions, such as prominent guitar solos in place of the breakdowns that were normally a staple part of the Chic sound, and some unusual lyrical subject matter, such as the sci-fi themed "Spacer" and a humorous song about credit cards. Background ''King of the World'' was one of four albums to be written and produced by Edwards and Rodgers in 1980, the other three being Sister Sledge's '' Love Somebody Today'', Chic's fourth studio album ''Real People'' and Diana Ross' multiplatinum selling '' Diana''. ''King of the World'' was first released on com ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Robot Series
The ''Robot'' series is a series of 37 science fiction short stories and six novels by American writer Isaac Asimov, featuring positronic robots. Later, Asimov would merge the ''Robot'' series with his ''Foundation'' series. Robot novels and stories The series started in 1940, with the story "Robbie" in the September 1940 ''Super Science Stories'' (appearing under the title "Strange Playfellow", which was not Asimov's title). Although it was originally written as a stand-alone story, the following year Asimov published a series of additional robot stories, which fit together into a narrative that was then put together as the book ''I, Robot''. List of works in the Robot series, in chronological order by narrative # ''I, Robot'' (1950) and later collections: ''The Complete Robot'' (1982), ''Robot Dreams'' (1986), ''Robot Visions'' (1990), and ''Gold'' (1995). #* In 1964, ''The Rest of the Robots'' was published - all of the short stories in that collection are found in ...

Asthma Spacer
A spacer is a device used to increase the ease of administering aerosolized medication from a metered-dose inhaler (MDI). It adds space in the form of a tube or "chamber" between the mouth and canister of medication. Most spacers have a one-way valve that allows the person to inhale the medication while inhaling and exhaling normally; these are often referred to as valved holding chambers (VHC). AeroChamber, InspirEase and Volumatic are examples of a spacer. Spacers help those unable to breathe deeply, as well as those unable to synchronize their breathing so that they inhale just as the MDI is actuated; the latter is known as poor "hand-lung coordination". __TOC__ Terminology The term spacer is often used to refer to any tube-like MDI add-on device. Some spacers (e.g., InspirEase) utilize a collapsing bag design to provide visual feedback that successful inspiration is taking place. Another type (e.g., Volumatic) is transparent plastic in two vase-shaped parts that come together f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Orthodontic Spacer
Orthodontic separators (also known as spacers) are rubber bands or metal appliances used in orthodontics. Spacers are placed between the molars at the second orthodontic appointment before molar bands are applied. They are usually added a week before you get your braces, but can sometimes be added after. Spacers are either circular rubber bands about a centimeter in diameter placed between top and bottom molars; there may be 1-12 spacers applied or small metal spring clips (spring separators) that push the molars apart. The spacers stay between the teeth for one week and move the teeth apart slowly until they are far apart enough so that orthodontists can fit a tooth brace or molar band in between them or fit an expander with rubber rings or other appliances. Purpose Spacers are usually used to put spaces in between teeth before braces are established. It can be agitating or painful, but patients are often warned not to pick at them or they will fall out. They are usually r ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spacer DNA
Spacer DNA is a region of non-coding DNA between genes. The terms intergenic spacer (IGS) or non-transcribed spacer (NTS) are used particularly for the spacer DNA between the many tandemly repeated copies of the ribosomal RNA genes. In bacteria, spacer DNA sequences are only a few nucleotides long. In eukaryotes, they can be extensive and include repetitive DNA, comprising the majority of the DNA of the genome. In ribosomal DNA, there are spacers within and between gene clusters, called internal transcribed spacer (ITS) and external transcribed spacers (ETS), respectively. In animals, the mitochondrial DNA genes generally have very short spacers. In fungi, mitochondrial DNA spacers are common and variable in length, and they may also be mobile. Due to the non-coding nature of spacer DNA, its nucleotide sequence changes much more rapidly over time than nucleotide sequences coding for genes that are subject to selective forces. Although spacer DNA might not have a function that de ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Joint Replacement
Replacement arthroplasty (from Greek ''arthron'', joint, limb, articulate, + ''plassein'', to form, mould, forge, feign, make an image of), or joint replacement surgery, is a procedure of orthopedic surgery in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies. It is a form of arthroplasty, and is often indicated from various joint diseases, including osteoarthritis and rheumatoid arthritis. Joint replacement surgery has become more common, with knees and hips replaced most often. About 773,000 Americans had a hip or knee replaced in 2009.Joint Replacement Surgery and You.

Web Design
Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; user interface design (UI design); authoring, including standardised code and proprietary software; user experience design (UX design); and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. The term "web design" is normally used to describe the design process relating to the front-end (client side) design of a website including writing markup. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and be up to date with web accessibility guidelines. History 1988–2001 Although web design has a fairly recent history, it can be linked to other areas such as graphic design, user experience, and multimedia ar ...

Spacers And Standoffs
In general, a spacer is a solid material used to separate two parts in an assembly. Spacers can vary in size from microns to centimeters. They can be made of metal, plastic, glass, and other materials. Shapes include flat sheet, cylindrical and spherical. A standoff is a threaded separator of defined length used to raise one part in an assembly above another. They are usually round or hex (for wrench tightening), often made of stainless steel, aluminum, brass, or nylon, and come in male-female or female-female forms. In electronics they are frequently used to raise a printed-circuit board above a surface. Insulating standoffs keep two parts from touching each other, thereby preventing electrical shorts. In some cases (e.g., D-subminiature connectors), short standoffs may be used to receive the jackscrews that lock the connection together. Both Spacers and Standoffs come in Round and Hex shapes with male and female threads. Knurling on the outside surface can also be done to prov ...

Rebar Spacer
A rebar spacer is a device that secures the reinforcing steel or "rebar" in reinforced concrete structures as the rebar is assembled in place before the final concrete pour. The spacers are left in place for the pour to keep the reinforcing in place and become a part of the structure. The main categories of rebar spacers are: * Linear Spacers (Π-section profiles, H-section profiles, or other 3-dimensional shapes), * Point Spacers (wheel spacers, various tower or chair-like shapes) Rebar spacers can be divided into three raw materials categories: # Concrete spacers # Plastic spacers # Metal spacers The concrete spacers have the advantage of the same raw material which will improve the water tightness and strength of the concrete. Plastic spacers have the advantage of low-cost production and fast processing, but are relatively weak. Metal spacers are strong but may rust. Function The engineering study of every reinforced concrete construction, whether it is a building ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drilling Fluid
In geotechnical engineering, drilling fluid, also called drilling mud, is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. One of the functions of drilling mud is to carry cuttings out of the hole. The three main categories of drilling fluids are: water-based muds (WBs), which can be dispersed and non-dispersed; non-aqueous muds, usually called oil-based muds (OBs); and gaseous drilling fluid, in which a wide range of gases can be used. Along with their formatives, these are used along with appropriate polymer and clay additives for drilling various oil and gas formations. The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending t ...
