A cartridge that does not contain primer, propellant, or explosive charge and therefore cannot befired.

Artifact peaks in capillary electropherograms arising from fluorescent dye molecules coming off their associated PCR primer during primer synthesis (and failing to be purified); generally, dye blob peaks are wider than true STR alleles, are lower in signal intensity, and can be characteristically sized in each color channel.

An imaging process that uses thermal dye ribbons with selected organic dyes, the imaging characteristics of which are different from the pigmented materials used in thermal transfer wax ribbons.

This stands for two separate application profiles of the ANSI/NIST-ITL standard:a) Acronym for the FBI's application profile of the ANSI/NIST-ITL standard:Electronic Biometric Transmission Specification.b) Acronym for the US Department of Defense's application profile of theANSI/NIST-ITL standard: Electronic Biometric TransmissionSpecification.

Temperatures reached in fires that produce physical effects that can be related to specific temperature ranges.

Extended Feature Set for markup of friction ridge data [2015a>]as defined in fields9.300-9.399 [

The FBI's earlier application profile of the ANSI/NIST-ITL standard: Electronic FingerprintTransmission Specification. It has been superseded by EBTS.

The distribution of fired cartridge cases or shotshells relative to the location of a firearm from which they were fired.

A disease of the elbow joint of canines caused by growth disturbances in the elbow joint.

A small, incandescent particle created by some arcs.

A typewriter in which an electromechanical device causes the type element to be activated when the keys are struck. (ASTM F909)

Emission or transfer of energy in the form of electromagnetic waves with the associated photons. 

NOTE The French term "radiation" applies preferably to a single element of any radiation, characterized by one wavelength or one frequency. (CIE S 017/E:2021 ILV)

Text, image files, spreadsheets, or other documents generated by computer on any media or device for any electronic processing. Electronically stored documents follow no format or readability requirements except when retrieved for human-use.

Digital data embedded in a digital file for the purposes of authentication, which may consist of a password, a photo, biometric data (DCS, fingerprint, etc.), One-Time-Passwords, voice recording, etc.

An electric typewriter in which the keyboard input is received by an electronic processor built into the typewriter. This unit then controls the print head and other features to produce the typing action. (ASTM F909)

A broad concept that includes public or private information stored in an electronic or digital medium, such as data available from computers (including email), CD-ROM discs, DVDs, Internet, cloud storage, personal digital assistants (PDAs), smart phones, tablets, GPS systems, satellites, and drones. ESI includes writings, drawings, graphs, charts, photographs, sound recordings, images, video recordings, data compilations, computer-aided design files such as blueprints or maps, metadata, equipment/process control and data logging system files, and any other data that is stored electronically.

A plot of fluorescence units over time showing the measured peaks of a DNA molecule atvarious genetic locations.

The graphic representation of the separation of molecules by electrophoresis in which the STR DNA data appear as peaks; the format in which DNA typing results are presented, with the X axis displaying the observed alleles based on fragment size and migration time and the Y axis recording the relative amount of DNA detected based on the relative fluorescent unit (RFU) collected during analysis.

A technique used in laboratories to separate macromolecules based on size. Charged molecules (e.g. proteins, DNA and RNA) migrate towards an oppositely charged pole through a sieving matrix, which permits a size-dependent separation.

A technique used in laboratories to separate macromolecules based on size and charge. Negatively charged molecules (e.g. DNA and RNA) migrate towards a positively charged pole through a sieving matrix, which permits a size-dependent separation.

A non-impact printing process in which the image is formed using photoconductive paper or a photoconductive intermediate drum.

The examination of (writing) indentations of paper.

An instrument that uses an electrostatic charge along with toner distribution as the mechanism to visualize paper fiber disturbances (for example, indentations and erasures). (ANSI/ASB Std 044)

In XML, an element is a building block delimited by a start-tag (for example:) and an end-tag (for example: ). Everything between thestart-tag and the end-tag of the element (exclusive) is called the element's content. Thefields, subfields, and information items used by traditional-encoding (non-XML)are all represented by XML elements in this encoding.

The interchangeable typeface carrier of a single element typewriter. See ball element, daisy wheel element, thimble element.
(SWGDOC E04-13)

an element that can be found in a pGSR particle. 

See vertical angle.

Footwear or tires, or recordings of footwear outsoles or tire treads, from known sources for the purpose of comparing to the questioned impressions.
