Standing Elk
Standing, also referred to as orthostasis, is a position in which the body is held in an ''erect'' ("orthostatic") position and supported only by the feet. Although seemingly static, the body rocks slightly back and forth from the ankle in the sagittal plane. The sagittal plane bisects the body into right and left sides. The sway of quiet standing is often likened to the motion of an inverted pendulum. Standing at attention is a military standing posture, as is stand at ease, but these terms are also used in military-style organisations and in some professions which involve standing, such as modeling. ''At ease'' refers to the classic military position of standing with legs slightly apart, not in as formal or regimented a pose as standing at attention. In modeling, ''model at ease'' refers to the model standing with one leg straight, with the majority of the weight on it, and the other leg tucked over and slightly around. Control Standing posture relies on dynamic rather than st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fractal
In mathematics, a fractal is a geometric shape containing detailed structure at arbitrarily small scales, usually having a fractal dimension strictly exceeding the topological dimension. Many fractals appear similar at various scales, as illustrated in successive magnifications of the Mandelbrot set. This exhibition of similar patterns at increasingly smaller scales is called self-similarity, also known as expanding symmetry or unfolding symmetry; if this replication is exactly the same at every scale, as in the Menger sponge, the shape is called affine self-similar. Fractal geometry lies within the mathematical branch of measure theory. One way that fractals are different from finite geometric figures is how they scale. Doubling the edge lengths of a filled polygon multiplies its area by four, which is two (the ratio of the new to the old side length) raised to the power of two (the conventional dimension of the filled polygon). Likewise, if the radius of a filled sphere i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standing Desk
A standing desk or stand-up desk is a desk conceived for writing, reading or drawing while standing up or while sitting on a high stool. History Several writers and statesmen wrote standing up: Thomas Jefferson, Charles Dickens, Winston Churchill, Ernest Hemingway, Henry Wadsworth Longfellow and Vladimir Nabokov. Some of them had specially made desks or lecterns. Variations Standing desks have been made in many styles and variations. Standing desks may be specialized to suit particular tasks, such as certain variations of the telephone desk and desks for architectural drafting. Some standing desks may only be used while standing while others allow users to sit or stand by adjusting the desk height with an electric motor, hand crank, or counterbalance system. Some desks are also constructed like teacher's lecterns, allowing them to be set on top of an existing desk for standing, or removed for sitting. While height of most seated desks is standardized, standing desks are ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prostration
Prostration is the gesture of placing one's body in a reverentially or submissively prone position. Typically prostration is distinguished from the lesser acts of bowing or kneeling by involving a part of the body above the knee, especially the hands, touching the ground. Major world religions employ prostration as an act of submissiveness or worship to a God, supreme being or other worshiped entity (i.e. God), as in the ''metanoia'' in Christian prayer used in the Eastern Orthodox and Oriental Orthodox Churches and the ''sajdah'' of the Islamic prayer, ''salat''. In various cultures and traditions, prostrations are similarly used to show respect to rulers, civil authorities and social elders or superiors, as in the Culture of China, Chinese kowtow or Ancient Greek ''proskynesis''. The act has often traditionally been an important part of religious, civil and traditional rituals and ceremonies, and remains in use in many cultures. Traditional religious practices Many relig ...

Human Position
Human positions refer to the different physical configurations that the human body can take. There are several synonyms that refer to human positioning, often used interchangeably, but having specific nuances of meaning. *''Position'' is a general term for a configuration of the human body. *''Posture (psychology), Posture'' means an intentionally or habitually assumed position. *''Pose'' implies an artistic, aesthetic, athletic, or spiritual intention of the position. *''Attitude'' refers to postures assumed for purpose of imitation, intentional or not, as well as in some standard collocations in reference to some distinguished types of posture: "Freud never assumed a fencing, fencer's attitude, yet almost all took him for a swordsman." *''Bearing'' refers to the manner of the posture, as well as of gestures and other aspects of the conduct taking place. Basic positions While not moving, a human is usually in one of the following basic positions: All-fours This is the static ...

Agonoclita
Agonoclita or the Agonoclites in antiquity was a Christian sect from the 7th century whose distinguishing principle was never to kneel, but to deliver all their prayers standing. Etymology The name of this group is derived from the following Greek words: the privative A privative, named from Latin language, Latin ''wikt:privare, privare'', "to deprive", is a particle (grammar), particle that negates or inverts the semantics, value of the root word, stem of the word. In Indo-European languages many privatives are ... particle ''α'' ("not"), ''γονυ'' ("knee"), and ''κλινω'' ("I bend"). References See also 7th-century Christianity {{Christian-denomination-stub ...

At Attention
The position of at attention, or standing at attention, is a military posture which involves the following general postures: * Standing upright with an assertive and correct posture: famously "chin up, chest out, shoulders back, stomach in". * Arms fixed at the side, thumb or middle finger parallel to trouser or skirt seam, depending on military drill specifics. * "Eyes front": head and eyes locked in a fixed forward posture. Ideally eyes unmoving fixated on a distant object. Blank facial expression. * Keeping the heels together, with the toes apart with the feet at a 45 degree angle. * No speech, facial or bodily movements except when as required by military drill. The above stance position is common in most military organizations throughout the world. It may also be adopted by paramilitary organizations, law enforcement, and other organizations requiring a loosely military structure such as Scouts, cadet programs, or police units, or even the Salvation Army. It is also use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypercoagulability
Thrombophilia (sometimes called hypercoagulability or a prothrombotic state) is an abnormality of blood coagulation that increases the risk of thrombosis (blood clots in blood vessels). Such abnormalities can be identified in 50% of people who have an episode of thrombosis (such as deep vein thrombosis in the leg) that was not provoked by other causes. A significant proportion of the population has a detectable thrombophilic abnormality, but most of these develop thrombosis only in the presence of an additional risk factor. There is no specific treatment for most thrombophilias, but recurrent episodes of thrombosis may be an indication for long-term preventive anticoagulation. The first major form of thrombophilia to be identified by medical science, antithrombin deficiency, was identified in 1965, while the most common abnormalities (including factor V Leiden) were described in the 1990s. Signs and symptoms The most common conditions associated with thrombophilia are deep v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coagulation Factor
Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The mechanism of coagulation involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin. Coagulation begins almost instantly after an injury to the endothelium lining a blood vessel. Exposure of blood to the subendothelial space initiates two processes: changes in platelets, and the exposure of subendothelial tissue factor to plasma factor VII, which ultimately leads to cross-linked fibrin formation. Platelets immediately form a plug at the site of injury; this is called ''primary hemostasis. Secondary hemostasis'' occurs simultaneously: additional coagulation (clotting) factors beyond factor VII ( listed below) respond in a cascade to form fibrin strands, which strengthen the platelet plug. Disorders of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasma Shift
Blood plasma is a light amber-colored liquid component of blood in which blood cells are absent, but contains proteins and other constituents of whole blood in suspension. It makes up about 55% of the body's total blood volume. It is the intravascular part of extracellular fluid (all body fluid outside cells). It is mostly water (up to 95% by volume), and contains important dissolved proteins (6–8%; e.g., serum albumins, globulins, and fibrinogen), glucose, clotting factors, electrolytes (, , , , , etc.), hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood-related disorders. Blood plasma is separated from the blood by spinning a vessel of fresh blood containing an anticoagulant in a centrifuge until the blood cells fall to the bottom of the tube. The blood plasma is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extravascular Compartment
The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and extracellular compartments. The intracellular compartment is the space within the organism's cells; it is separated from the extracellular compartment by cell membranes. About two-thirds of the total body water of humans is held in the cells, mostly in the cytosol, and the remainder is found in the extracellular compartment. The extracellular fluids may be divided into three types: interstitial fluid in the "interstitial compartment" (surrounding tissue cells and bathing them in a solution of nutrients and other chemicals), blood plasma and lymph in the "intravascular compartment" (inside the blood vessels and lymphatic vessels), and smal ...

Transcapillary Hydrostatic Pressure
The Starling equation describes the net flow of fluid across a semipermeable membrane. It is named after Ernest Starling. It describes the balance between capillary pressure, interstitial pressure, and osmotic pressure. The classic Starling equation has in recent years been revised. The Starling principle of fluid exchange is key to understanding how plasma fluid (solvent) within the bloodstream (intravascular fluid) moves to the space outside the bloodstream (extravascular space). Transendothelial fluid exchange occurs predominantly in the capillaries, and is a process of plasma ultrafiltration across a semi-permeable membrane. It is now appreciated that the ultrafilter is the glycocalyx of the plasma membrane of the endothelium, whose interpolymer spaces function as a system of small pores, radius circa 5 nm. Where the endothelial glycocalyx overlies an inter endothelial cell cleft, the plasma ultrafiltrate may pass to the interstitial space. Some continuous capillaries m ...
