.38 caliber pistol

Sometimes known as a .38 special, this caliber of gun can be found with either a revolving or a semi-automatic firing mechanism. In addition, the bullets fired from this gun can be either center-fired or rimmed. Center-fire cartridges are primed and struck in the center of the cartridge base, whereas rim-fire cartridges are primed and struck on the protruding rim on the base of the cartridge. Due to its minimal recoil, which is the reactive movement of a gun after firing, and its accuracy, the .38 caliber is a popular gun.

semi-trailer rig

A large transport truck that consists of a tractor unit in the front onto which one or more wheeled freight trailers can be hitched. These trucks are called semi-trailer because the cargo units only have wheels in the back, and their front part must be attached to the towing tractor.


The diameter measurement of either a bullet or the internal width of a gun barrel. The caliber is usually measured in hundredths of an inch, for example .22, .38, and so on.


A substance used in medical procedures to paralyze sensory nerve endings and/or nerve fibers, thus producing loss of sensation. Anesthetic substances enable patients to undergo operations and other invasive procedures that involve severe pain.

bifocal glasses

Prescription glasses in which the lenses are horizontally divided into two parts, each with a different refractive strength. Usually the upper part is for distant or normal vision, while the lower part is for reading or other close-up work.


An archival, or preservation and storage, medium in which written material, such as official or personal letters, newspapers, and other printed ephemera, are photographed using a technique that reduces the size of the document to at least one-quarter of its original size. This allows for large volumes of space to be saved, as the microfilm can contain hundreds of documents in one roll, while also providing easy-to-read photographic reproductions that degrade at a slower rate than paper documents. To view microfilmed material, the reel of film must be inserted into a special magnifying device that then brings the image up on a screen while enlarging it back to its original size. Microfilm technology has in great part been replaced by digitized versions of these same sources, although many repositories still retain microfilm collections.

Central Intelligence Agency

The Central Intelligence Agency (CIA) is a special division of the U.S. government that is in charge of foreign information operations. It was created as part of the National Security Act in 1947, which was amended again in 2004 with the Intelligence Reform and Terrorism Prevention Act. The CIA is a secret service known for its high-tech, innovative modes of gathering information and executing special national security operations.It is also known for promulgating and participating in secretive abuses of power, including torture. The primary function of the CIA is to collect information related to national security, mainly through human sources. In recent decades, however, the agency increasingly utilizes cyber technology to collect and analyze information pertinent to counterterrorism, international crime organizations, and drug trafficking.
