Ballistic Trauma
A gunshot wound (GSW) is a penetrating trauma, penetrating injury caused by a projectile (e.g. a bullet) Shooting, shot from a gun (typically a firearm). Damage may include bleeding, bone fractures, organ (anatomy), organ damage, wound infection, and Plegia, loss of the ability to move part of the body. Damage depends on the part of the body hit, the path the bullet follows through (or into) the body, and the type and speed of the bullet. In severe cases, although not uncommon, the injury is Death, fatal. Long-term complications can include bowel obstruction, failure to thrive, neurogenic bladder and paralysis, recurrent cardiorespiratory distress and pneumothorax, hypoxic brain injury leading to early dementia, amputations, chronic pain and pain with light touch (hyperalgesia), deep venous thrombosis with pulmonary embolus, limb swelling and Debility (medical), debility, and lead poisoning. Factors that determine rates of gun violence vary by country. These factors may include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Skull
The skull, or cranium, is typically a bony enclosure around the brain of a vertebrate. In some fish, and amphibians, the skull is of cartilage. The skull is at the head end of the vertebrate. In the human, the skull comprises two prominent parts: the neurocranium and the facial skeleton, which evolved from the first pharyngeal arch. The skull forms the frontmost portion of the axial skeleton and is a product of cephalization and vesicular enlargement of the brain, with several special senses structures such as the eyes, ears, nose, tongue and, in fish, specialized tactile organs such as barbels near the mouth. The skull is composed of three types of bone: cranial bones, facial bones and ossicles, which is made up of a number of fused flat and irregular bones. The cranial bones are joined at firm fibrous junctions called sutures and contains many foramina, fossae, processes, and sinuses. In zoology, the openings in the skull are called fenestrae, the ...

Illegal Drug Trade
The illegal drug trade, drug trafficking, or narcotrafficking is a global black market dedicated to the cultivation, manufacture, distribution and sale of drug prohibition, prohibited drugs. Most jurisdictions prohibitionism, prohibit trade, except under license, of many types of drugs through the use of drug prohibition laws. The think tank Global Financial Integrity's ''Transnational Crime and the Developing World'' report estimates the size of the global illicit drug market between US$426 and US$652billion in 2014, which is equal to the UK's national debt alone. With a Gross world product, world GDP of US$78 trillion in the same year, the illegal drug trade may be estimated as nearly 1% of total global trade. Consumption of illegal drugs is widespread globally, and it remains very difficult for local authorities to reduce the rates of drug consumption. History Prior to the 20th century, governments rarely made a major effort to proscribe recreational drug use, though sever ...

Bone Fracture
A bone fracture (abbreviated FRX or Fx, Fx, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a ''comminuted fracture''. An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. A bone fracture may be the result of high force Impact force, impact or Stress fracture, stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture. Most bone fractures require urgent medical attention to prevent further injury. Signs and symptoms Although bone tissue contains no nociceptors, pain receptors, a bone fracture is painful for several reasons: * Breaking in the continuity of the periosteum, with or without similar disconti ...

Firearm
A firearm is any type of gun that uses an explosive charge and is designed to be readily carried and operated by an individual. The term is legally defined further in different countries (see legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other explosive propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stabili ...

Shooting
Shooting is the act or process of discharging a projectile from a ranged weapon (such as a gun, bow, crossbow, slingshot, or blowpipe). Even the acts of launching flame, artillery, darts, harpoons, grenades, rockets, and guided missiles can be considered acts of shooting. When using a firearm, the act of shooting is often called firing as it involves initiating a combustion ( deflagration) of chemical propellants. Shooting can take place in a shooting range or in the field, in shooting sports, hunting, or in combat. The person involved in the shooting activity is called a shooter. A skilled, accurate shooter is a ''marksman'' or ''sharpshooter'', and a person's level of shooting proficiency is referred to as their ''marksmanship''. Competitive shooting Shooting has inspired competition, and in several countries rifle clubs started to form in the 19th century. Soon international shooting events evolved, including shooting at the Summer and Winter Olympics (from 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullet
A bullet is a kinetic projectile, a component of firearm ammunition that is shot from a gun barrel. They are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax; and are made in various shapes and constructions (depending on the intended applications), including specialized functions such as hunting, target shooting, training, and combat. Bullets are often tapered, making them more aerodynamic. Bullet size is expressed by weight and diameter (referred to as "caliber") in both imperial and metric measurement systems. Bullets do not normally contain explosives but strike or damage the intended target by transferring kinetic energy upon impact and penetration. Description The term ''bullet'' is from Early French, originating as the diminutive of the word ''boulle'' (''boullet''), which means "small ball". Bullets are available singly (as in muzzle-loading and cap and ball firearms) but are more often packaged with propellant as a cartri ...

Projectile
A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports (for example, a thrown baseball, kicked football, fired bullet, shot arrow, stone released from catapult). In ballistics, mathematical equations of motion are used to analyze projectile trajectories through launch, flight, and impact. Motive force Blowguns and pneumatic rifles use compressed gases, while most other guns and cannons utilize expanding gases liberated by sudden chemical reactions by propellants like smokeless powder. Light-gas guns use a combination of these mechanisms. Railguns utilize electromagnetic fields to provide acceleration along the entire length of the device, greatly increasing the muzzle velocity. Some projectiles provide propulsion during flight by means of a rocket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Injury
Injury is physiological damage to the living tissue of any organism, whether in humans, in other animals, or in plants. Injuries can be caused in many ways, including mechanically with penetration by sharp objects such as teeth or with blunt objects, by heat or cold, or by venoms and biotoxins. Injury prompts an inflammatory response in many taxa of animals; this prompts wound healing. In both plants and animals, substances are often released to help to occlude the wound, limiting loss of fluids and the entry of pathogens such as bacteria. Many organisms secrete antimicrobial chemicals which limit wound infection; in addition, animals have a variety of immune responses for the same purpose. Both plants and animals have regrowth mechanisms which may result in complete or partial healing over the injury. Cells too can repair damage to a certain degree. Taxonomic range Animals Injury in animals is sometimes defined as mechanical damage to anatomical struct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penetrating Trauma
Penetrating trauma is an open wound injury that occurs when an object pierces the Human skin, skin and enters a tissue (biology), tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a blunt trauma, blunt or ''non-penetrating'' trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment. The penetrating object may foreign body, remain in the tissues, come back out the path it entered, or pass through the full thickness of the tissues and exit from another area. A penetrating injury in which an object enters the body or a structure and passes all the way through an exit wound is called a perforating trauma, while the term ''penetrating trauma'' implies that the object does not perforate wholly through. In gunshot wounds, perforating trauma is associated with an entrance wound and an often larger exit wound. Penetrating trauma can be caused by a foreign object or by fragm ...

Crime Prevention
Crime prevention refers to strategies and measures that seek to reduce the risk of crime occurring by intervening before a crime has been committed. It encompasses many approaches, including developmental, situational, community-based and criminal-justice interventions, to address risk factors at individual, family, community and societal levels. These strategies aim to deter potential offenders, reduce opportunities for offending and mitigate the fear of crime among the public, and are used by many governments in their efforts to reduce crime, enforce the law, maintain criminal justice and uphold overall stability. Studies Criminologists, commissions and research bodies such as the World Health Organization, the United Nations, the United States National Research Council and the UK Audit Commission have analyzed their and others' research on what lowers the rates of interpersonal crime. They agree that governments must go beyond law enforcement and criminal justice to tackle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firearm Safety
Gun safety is the study and practice of managing risk when using, transporting, storing and disposing of firearms, airguns and ammunition in order to avoid injury, illness or death. Gun safety includes the training of users, the design of firearms, as well as the formal and informal regulation of gun production, distribution, and usage. This includes mishaps like accidental discharge, negligent discharge, and firearm malfunctions, as well as secondary risks like hearing loss, lead poisoning from bullets, and pollution from other hazardous materials in propellants and cartridges. History Accidental explosions of stored gunpowder date to the 13th century in Yangzhou, China. Early handheld muskets using matchlock or wheel lock mechanisms were limited by poor reliability and the risk of accidental discharge, which was improved somewhat by the introduction of the flintlock, though unintentional firing continued to be a serious drawback.
