A wound is type of physical trauma wherein the skin is torn, cut or punctured (an open wound), or where blunt force trauma causes a contusion (a closed wound). Before any medical or paramedical evaluation, a wound is considered as minor when: it is superficial (a "flesh wound"); it is away from natural orifices; there is only a minor bleeding; it was not caused by a tool or an animal. Any other wound should be considered as severe. If there is any doubt, ...

The vast majority of chronic wounds can be classified into three categories: venous, diabetic, and pressure ulcers (Mustoe, 2004; Moreo, 2005) CW. A small number of wounds that do not fall into these categories may be due to causes such as radiation poisoning or ischemia (Mustoe, 2004). Chronic wound - Venous ulcers. Venous ulcers, which usually occur in the legs, exist in about 70% to 90% of chronic wounds (Snyder, 2005) and mostly affect the elderly. They are thought to be due to venous hypertension caus ...

Velvet is a type of tufted fabric in which the cut threads are very evenly distributed, with a short dense pile, giving it its distinct feel. Velvet can be made from any fiber. It is woven on a special loom that weaves two pieces of velvet at the same time. The two pieces are then cut apart and the two lengths of fabric are wound on separate take-up rolls. Velvet's knitted counterpart is velour. Velvet was very expensive and was considered to be among the luxury goods together with silk. Corduroy and velveteen were considered the "poor ...

Bobbin lace is a delicate lace that uses wound spools of thread (the bobbins) to weave together the shapes in the lace. The lace is held in place with very fine lace pins while being worked and is made on a lace pillow (a cloth form traditionally stuffed with straw or sawdust). Pairs of bobbins are twisted or braided to form meshes (also called "ground") or woven to form solid shapes, depending on the type of lace made. Many styles of lace were made in the heyday of lacemaking (that stretched possibly between the 1500s ...

Angiogenesis is the physiological process involving the formation of new blood vessels from pre-existing vessels. Though there has been some debate over this, vasculogenesis is the term used for spontaneous blood-vessel formation. Angiogenesis is a normal process in growth and development, as well as in wound healing. However, this is also a fundamental step in the transition of tumors from a dormant state to a malignant state. Angiogenesis - Types of Angiogenesis. Angiogenesis - Sprouting An ...

Bleeding is the loss of blood from the body. Children are put more in danger by bleeding as they have less blood to lose. The average adult human will be in medical danger after 2 liters (2 quarts) and could die of hypovolemic shock if more blood is lost. The complete loss of blood is referred to as exsanguination.

The harp is a chordophone which has its strings positioned perpendicular to the soundboard. All harps have a neck, resonator and strings. Some, known as frame harps, also have a forepillar; those lacking the forepillar are referred to open harps. Harp strings can be made of nylon (sometimes copper-wound), gut (more commonly used than nylon), or wire. Various types of harps are found in Africa, Europe, North and South America, and a few parts of Asia. In Antiquity harps and the closely related Lyras were very promi ...

Twisted pair cabling is a common form of wiring in which two conductors are wound around each other for the purposes of canceling out electromagnetic interference which can cause crosstalk. The number of twists per meter make up part of the specification for a given type of cable. The greater the number of twists, the more crosstalk is reduced. Twisting wires decreases interference because: The loop area between the wires (which determines the magnetic coupling into the signal) is reduced as much as physically possible. The directions of current generated by a uniform coupled magnetic field is reverse ...

In addition to poor circulation, neuropathy, and difficulty moving, factors that contribute to chronic wounds include systemic illnesses, age, and repeated trauma (Yaple, 2005). Comorbid ailments that may contribute to the formation of chronic wounds include vasculitis (an inflammation of blood vessels), immune suppression, pyoderma gangrenosum, and diseases that cause ischemia (Snyder, 2005). Immune suppression can be caused by illnesses or medical drugs used over a long period, for example steroids (Snyder, 2005). Emotional stress can also ...

Chronic wounds may affect only the epidermis and dermis, or they may affect tissues all the way to the fascia (Crovetti et al., 2004). They may be formed originally by the same things that cause acute ones, such as surgery or accidental trauma (Moreo, 2005), or they may form as the result of systemic infection, vascular, immune, or nerve insufficiency, or comorbidities such as neoplasias or metabolic disorders (Crovetti et al., 2004). The reason a wound becomes chronic is that the body’s ability to deal with the damage is overwhelmed by factors such as repeated trauma, continued pressure, ischemia, ...

When the levels of collagen production and degradation equalize, the maturation phase of tissue repair is said to have begun (Greenhalgh, 1998). The maturation phase can last for a year or longer, depending on the size of the wound and whether it was initially closed or left open (Greenhalgh, 1998; DiPietro and Burns, 2003; Mercandetti and Cohen, 2005). During Maturation, type III collagen, which is prevalent during proliferation, is gradually degraded and the stronger type I is laid down in its place (Stadelmann et al, 1998; Dealey, 1999; R ...

Aluminum is the most common for bowed instruments like violin and viola, while guitar and piano strings are usually wound with bronze; copper, chrome and silver are also used. Although silver is more expensive, it is preferred for its resistance to corrosion and hypoallergenicity. Strings wound with round wire are called round wound; those wound with flat wire (giving a smoother surface) are called flatwound. There is also a winding type called "ground round", where the winding is ground flat to an even smoother fi ...

Bleeding - Minor traumatic bleeding. The minor traumatic bleeding stops spontaneously, the loss of blood is not dangerous in itself. But the wound can still endanger the life of the casualty. See Wound. Bleeding - Severe traumatic bleeding. The general behaviour is: protect: remove the cause of wound so nobody else gets hurt, or lead the casualty away and mark out the dangerous area; when the casualty cannot walk, do not move him unless the danger is deadly and rea ...

The incubation period for tetanus is 3 days to as long as 15 weeks (with the average being about 8 days) [2]. For neonates, the incubation period is 4 to 14 days, with 7 days being the average. Most of the time, the further the wound is from the central nervous system, the longer the incubation period. Incubation period length and likelihood of death are inversely proportional; a deep, contaminated wound that allows the bacteria to flourish and causes a quick, aggressive infection is much more life-threatening than a shallower, less-contaminated wound that causes milder sym ...
