26. FORENSIC BALLISTICS. CONCEPT AND CLASSIFICATION

FIREARMS AND AMMUNITION

The term "ballistics" comes from the Greek "ballo" - "throw".

Forensic ballistics - this is a section of forensic technology that studies firearms, ammunition, the patterns of a shot and its traces, develops means and techniques for collecting and examining these objects and traces of their use in order to detect, investigate and prevent crimes.

The tasks of forensic ballistics are:

1) identification of weapons and ammunition by traces of a shot;

2) establishing the group affiliation of weapons (type, system, model);

3) establishing the circumstances of the use of firearms - the distance of the shot, the location of the shooter, the direction of the shot, the number and sequence of shots.

The objects of forensic ballistic research are:

1) firearms, their separate parts;

2) ammunition for firearms, including fired bullets, spent cartridges, shot, buckshot, wads, etc.;

3) traces of the use of firearms;

4) procurement of weapon parts;

5) tools and various materials used in the manufacture of weapons and ammunition;

6) items in which weapons were kept.

Firearms - this is a device, structurally designed to hit a target with a projectile, which receives a directed movement due to the energy of a gas-forming substance.

Firearms are classified:

1) according to the intended purpose: civil; combat; military; hunting; sports; antique; criminal.

2) according to the device of the bore: rifled, smoothbore, combined;

3) along the length of the trunk: short-barreled (up to 20 cm); medium-barrel (from 20 to 40 cm); long-barreled (more than 40 cm);

4) by caliber: small-caliber (up to 6.5 mm inclusive); normal caliber (up to 9 mm inclusive); large-caliber (over 9 mm);

5) according to the method of loading: muzzle-loading (ramrod); breech-loading;

6) according to the used cartridges: central battle; ring ignition; side combat (Le Fauchet hairpin cartridges);

7) by the number of trunks: single-barrel; double-barreled; multi-stem;

8) by the number of charges: single-shot; multiply charged;

9) according to the action of the charging mechanism: non-automatic (store or drum); automatic (self-loading, self-firing, combined);

10) according to the manufacturing method: standard; non-standard;

11) by design (view): pistols, revolvers, submachine guns.

Ammunition - These are disposable items designed to hit a specific target by a shot or explosion.

Ammunition can be divided into two groups:

1) explosive action, which includes various types of grenades, factory-made mines, as well as home-made explosive devices;

2) small arms, which includes cartridges for small arms firearms. The cartridge consists of a cartridge case, a primer, gunpowder and a projectile.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Random news from the Archive The car will not hit a pedestrian 02.11.2014 Automaker Honda Motor has announced a new active safety system, with which the car will be able to independently avoid collisions with pedestrians and other vehicles. The technology, called Sensing, will first appear in the new version of the Legend business sedan, and will later be available in other models of the Japanese brand. The presented electronic assistant uses a special radar installed in the radiator grille and serves to recognize pedestrians. Their height can be determined by a camera placed at the top of the windshield. The system, analyzing the situation in front of the car at a distance of up to 60 meters, can calculate the likelihood of a collision with people walking nearby. The electronics will warn the driver about the danger with a sound and visual signal on the dashboard, and if necessary, slow down the car, stop it completely or make a safe maneuver. According to the developers, Sensing is able to predict the actions of other road users. In addition, when driving in a traffic jam, the technology will tell the person behind the wheel about an attempt to over-accelerate (the accelerator pedal will vibrate) and notify the need to start moving when the flow has started. Finally, Sensing has the capabilities of adaptive cruise control, lane keeping systems and traffic sign recognition. Honda will add Sensing to the facelifted Legend, which will hit the Japanese market in late 2014. Then other cars of the manufacturer will be equipped with the system.
