Collarbone Piercing
In body modification, an implant is a device that is placed under the human skin for decorative purposes. Such implants may be subdermal or transdermal. In the context of body modification, some may consider injections of silicone and other substances a type of implant as well. Some types of implants may be performed by doctors or other medical professionals, while others are performed by body modification artists. Implants and procedures Clavicle or collarbone piercing A very deep piercing that passes beneath the collarbone, and therefore enters the body cavity. These are highly prone to rejection as the collarbone placement is a high movement area. Also, because of the depth of the piercinggoing deep under the collarbone and through a large amount of flesh and musclehealing is difficult. With all the movement in the area the fistula cannot heal properly, and will hurt far worse than a hip piercing. Deep chest piercing A deep chest piercing is a long piercing that passes ...

Sonar
Sonar (sound navigation and ranging or sonic navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigation, navigate, measure distances (ranging), communicate with or detect objects on or under the surface of the water, such as other vessels. "Sonar" can refer to one of two types of technology: ''passive'' sonar means listening for the sound made by vessels; ''active'' sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used for robot navigation, and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations. The term ''sonar'' is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic ...

Mohawk Hairstyle
The mohawk (also referred to as a Mohican) is a hairstyle in which, in the most common variety, both sides of the head are shaven, leaving a strip of noticeably longer hair in the center. It is today worn as an emblem of non-conformity. The mohawk is also sometimes referred to as an iro in reference to the Iroquois (who include the Mohawk people), from whom the hairstyle is supposedly derived – though historically the hair was plucked out rather than shaved. Additionally, hairstyles bearing these names more closely resemble those worn by the Pawnee, rather than the Mohawk, Mohicans, Mohegan, or other groups whose names are phonetically similar. The world record for the tallest mohawk goes to Kazuhiro Watanabe, who has a tall mohawk. Name While the mohawk hairstyle takes its name from the people of the Mohawk nation, an indigenous people of North America who originally inhabited the Mohawk Valley in upstate New York, the association comes from Hollywood and more specifica ...

Transdermal Implant
Transdermal implants, or dermal piercings, are a form of body modification used both in a medical and aesthetic context. In either case, they consist of an object placed partially below and partially above the skin, thus ''trans''dermal. The skin around it generally heals as if it were a piercing. In the body piercing community, these types of modification are generally called fairly "heavy" due to the complexity of the procedure and the social implications. Two types of implants can be used. Procedure When the procedure is done using a post-like implant, an incision is made a small distance from the site. The skin is then lifted and the implant is passed through. Then, a hole is opened at the site for it to pass through, and it is moved so that the top part fills the hole. The implants used for this are generally small and not textured in any way except rounding. If a more graphic implant is desired, it is generally done in two parts. First, the base is inserted the same way a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sternum
The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. The word "sternum" originates from the Ancient Greek στέρνον (stérnon), meaning "chest". Structure The sternum is a narrow, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs. The inner surface of the sternum is also the attachment of the sternopericardial ligaments. Its top is also connected to the sternocleidomastoid muscle. The sternum consists of three main parts, listed from the top: * Manubrium * Body (gladiolus) * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nape Of The Neck
The nape is the back of the neck. In technical anatomical/medical terminology, the nape is also called the nucha (from the Medieval Latin rendering of the Arabic , "spinal marrow"). The corresponding adjective is ''nuchal'', as in the term ''nuchal rigidity'' for neck stiffness. In many mammals the nape bears a loose, non-sensitive area of skin, known as the scruff, by which a mother carries her young by her teeth, temporarily immobilizing it during transport. In the mating of cats the male will grip the female's scruff with his teeth to help immobilize her during the act, a form of pinch-induced behavioral inhibition Pinch-induced behavioural inhibition (PIBI), also called dorsal immobility, transport immobility or clipnosis, is a partially inert state which results from a gentle squeeze of the skin behind the neck. It is mostly observed among cats and allows .... Cultural connotations In traditional Japanese culture, the was one of the few areas of the body (other than f ...

Surface Piercing
Surface piercings are piercings that are found on flat parts of the body, giving a double-pierced look that sits flat against the skin. A surface bar follows the plane of skin, while a standard piercing is pierced through the plane. Standard piercings have an entrance hole with an exit hole that is usually directly behind the entrance hole, whereas with a surface piercing the entrance and exit holes are next to each other on the skin surface. Types Some examples of surface piercings: *Corset piercing: a series of bilaterally symmetrical piercings, normally done on the back, intended to be laced like a corset. *Christina piercing: located at the mons pubis. *Madison piercing: a horizontal piercing located just above the collarbone, at the base of the neck. *Nape piercing: located on the back of the neck. *Neck piercing: located on the side of the neck. It is also called "Vampire Bites". *Hip piercing: located on or beside the hips (on the pelvis near the hips bones). *Wrist piercin ...

RFID
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in many industries. For example, an RFID tag attached to an automobile during production can be used to track ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teflon
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. It is one of the best-known and widely applied PFAS. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low electric polarizability of fluorine. PTFE has one of the lowest coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PT ...

Norplant
Levonorgestrel-releasing implant, sold under the brand name Jadelle among others, are devices that release levonorgestrel for birth control. It is one of the most effective forms of birth control with a one-year failure rate around 0.05%. The device is placed under the skin and lasts for up to five years. It may be used by women who have a history of pelvic inflammatory disease and therefore cannot use an intrauterine device. Following removal fertility quickly returns. It is generally well tolerated with few significant side effects. Side effects may include irregular menstrual periods, no periods, headaches, and breast pain. Use is not recommended in people with significant liver disease. The levonorgestrel implant is a type of long-acting reversible birth control. It primarily works by stopping ovulation and by thickening the mucus around the cervix. A levonorgestrel-releasing implant was approved for medical use in 1983 in Finland and in the United States in 1990. It is ...

Pacemakers
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or pacemaker is a Implant (medicine), medical device that generates electrical impulses delivered by electrodes to the Heart chamber, chambers of the heart either the upper atrium (heart), atria, or lower ventricle (heart), ventricles to cause the targeted chambers to muscle contraction, contract and pump blood. By doing so, the pacemaker regulates the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's natural pacemaker is not fast enough, or because there is a heart block, block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist, particularly a cardiac electrophysiology, cardiac electrophysiologist, to select the optimal pacing modes for individual patients. Most pacemakers are on demand, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
