Wound Ballistics
The field of wound ballistics largely comprises the study of the physical and physiological effects of ballistic trauma by projectiles (primarily, but not exclusively, bullets) on living humans or animals. It can be considered the interdisciplinary intersection of trauma medicine and terminal ballistics. See also *Bullet hit squibs *Gunshot injury *Hydrostatic shock *Penetrating trauma *Sniper *Stopping power Stopping power is the ability of a weapon – typically a ranged weapon such as a firearm – to cause a target (human or animal) to be incapacitated or immobilized. Stopping power contrasts with lethality in that it pertains only to a weapon's ... Ballistics pl:Rana postrzałowa {{med-diagnostic-stub ...

Physiological
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine.

Ballistic Trauma
A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) from a gun (typically firearm or air gun). Damages may include bleeding, bone fractures, organ damage, wound infection, loss of the ability to move part of the body and, in more severe cases, death. Damage depends on the part of the body hit, the path the bullet follows through the body, and the type and speed of the bullet. Long-term complications can include lead poisoning and post-traumatic stress disorder (PTSD). Factors that determine rates of gun violence vary by country. These factors may include the illegal drug trade, easy access to firearms, substance misuse including alcohol, mental health problems, firearm laws, social attitudes, economic differences and occupations such as being a police officer. Where guns are more common, altercations more often end in death. Before management begins it should be verified the area is safe. This is followed by stopping major bleeding, then as ...

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 a constant acceleration along the entire length of the device, greatly increasing the muzzle velocity. Some projectiles provide propulsion during flight by means of a rocket engine ... [...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. Bullets are made of a variety of materials, such as copper, lead, steel, polymer, rubber and even wax. Bullets 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 sizes are expressed by their weights and diameters (referred to as " calibers") in both imperial and metric measurement systems. For example: 55 grain .223 caliber bullets are of the same weight and caliber as 3.56 gram 5.56mm caliber bullets. Bullets do not normally contain explosives but strike or damage the intended target by transferring kinetic energy upon impact and penetration. Bullets shot by firearms can be used for target practice or hunting. Description The term ''bullet'' is from Middle French, originating as the diminuti ...

Interdisciplinary
Interdisciplinarity or interdisciplinary studies involves the combination of multiple academic disciplines into one activity (e.g., a research project). It draws knowledge from several other fields like sociology, anthropology, psychology, economics, etc. It is about creating something by thinking across boundaries. It is related to an ''interdiscipline'' or an ''interdisciplinary field,'' which is an organizational unit that crosses traditional boundaries between academic disciplines or schools of thought, as new needs and professions emerge. Large engineering teams are usually interdisciplinary, as a power station or mobile phone or other project requires the melding of several specialties. However, the term "interdisciplinary" is sometimes confined to academic settings. The term ''interdisciplinary'' is applied within education and training pedagogies to describe studies that use methods and insights of several established disciplines or traditional fields of study.

Trauma Medicine
Trauma most often refers to: *Major trauma, in physical medicine, severe physical injury caused by an external source *Psychological trauma, a type of damage to the psyche that occurs as a result of a severely distressing event *Traumatic injury, sudden physical injury caused by an external force, which does not rise to the level of major trauma Trauma may also refer to: People * Trauma (wrestler) *Trauma II (born 1982), Mexican ''luchador enmascarado'', or masked professional wrestler Arts, entertainment, and media Films * ''Trauma'' (1962 film), an American film by Robert M. Young *''Red Rings of Fear'' (1978), a film sometimes known as ''Trauma'' * ''Trauma'' (1993 film), a horror film by Dario Argento * ''Trauma'' (2004 film), a psychological thriller by Marc Evans Music Groups and record labels *Trauma (American band), an American heavy metal band *Trauma (German band), a German trance band *Trauma (Polish band), a Polish death metal band *Trauma Records, a record labe ...

Terminal Ballistics
Terminal ballistics (also known as wound ballistics) is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determine the effectiveness of penetration. General The concept of terminal ballistics can be applied to any projectile striking a target. Much of the topic specifically regards the effects of small arms fire striking live targets, and a projectile's ability to incapacitate or eliminate a target. Common factors include bullet weight, composition, velocity, and shape. Firearm projectiles Classes of bullets There are three basic classes of bullets: * Those designed to maximize accuracy at varying ranges, * Those designed to maximize damage to a target (by penetrating as deeply as possible), * Those designed to avoid over-penetration of a target. This is done by deformation (to control the depth to which the bullet penetrates) which, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullet Hit Squibs
A bullet hit squib or a blood squib is a practical, pyrotechnic special effect device used in the film industry, theatre productions and first responder moulage training to simulate a bullet wound spurting blood. Typically, the effect is carried out with clothing instead of on bare skin in order to conceal the device. Even if the portrayal is not necessarily accurate or is exaggerated compared to real-life (in the example of the main figure, blood spews out of a thick coat while emitting smoke), filmmakers and the audience have become accustomed to associating this aesthetic with a gunshot wound. A bullet hit squib device comprises a squib (a small, firecracker-like explosive), an electric match, a small pack of simulant (most commonly fake blood), a protective plate and some padding attached to the actor's costume. The device is then connected to a battery and a remote, with which the squib can be triggered by the actor or a crew member, creating the visual effect of a gunsho ...

Gunshot Injury
A gunshot wound (GSW) is a penetrating injury caused by a projectile (e.g. a bullet) from a gun (typically firearm or air gun). Damages may include bleeding, bone fractures, organ damage, wound infection, loss of the ability to move part of the body and, in more severe cases, death. Damage depends on the part of the body hit, the path the bullet follows through the body, and the type and speed of the bullet. Long-term complications can include lead poisoning and post-traumatic stress disorder (PTSD). Factors that determine rates of gun violence vary by country. These factors may include the illegal drug trade, easy access to firearms, substance misuse including alcohol, mental health problems, firearm laws, social attitudes, economic differences and occupations such as being a police officer.

Hydrostatic Shock
Hydrostatic shock is the controversial concept that a penetrating projectile (such as a bullet) can produce a pressure wave that causes "remote neural damage", "subtle damage in neural tissues" and/or "rapid incapacitating effects" in living targets. It has also been suggested that pressure wave effects can cause indirect bone fractures at a distance from the projectile path, although it was later demonstrated that indirect bone fractures are caused by temporary cavity effects (strain placed on the bone by the radial tissue displacement produced by the temporary cavity formation). Proponents of the concept argue that hydrostatic shock can produce remote neural damage and produce incapacitation more quickly than blood loss effects. In arguments about the differences in stopping power between calibers and between cartridge models, proponents of cartridges that are "light and fast" (such as the 9×19mm Parabellum) versus cartridges that are "slow and heavy" (such as the .45 ACP) of ...

Penetrating Trauma
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound. In contrast, a 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 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 fragments of a broken bone. Usually occurring in violent cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sniper
A sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with high-precision rifles and high-magnification optics, and often also serve as scouts/observers feeding tactical information back to their units or command headquarters. In addition to long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, camouflage, tracking, bushcraft, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition. Etymology The name "sniper" comes from the verb "to snipe", which originated in the 1770s among soldiers in British India in reference to shooting snipes, a wader that was considered an extremely challenging game bird for hunters due to its alertness, camouflaging color ...
