The interval in human dental development that begins at birth, includes the presence of the developing, developed and resorbing primary dentition as well as the initial development of the permanent dentition. This interval includes the early period of mixed primary and permanent dentitions and ends when the last primary tooth is exfoliated normally. Note 1 to entry: During the adolescent age and adult dental age intervals, primary teeth may be atypically retained for various reasons, including congenital absence or ectopic eruption of the permanent teeth that would typically replace them.

IR Referring to radiant flux having wavelengths longer than the wavelengths of visible light, usually from ~700 nm to 1400 nm $(\sim0.7~\mu m$ to 1.4 µm) as per the International Commission on Illumination (CIE) for IR-A. (ANSI/ASB Std 035)

IRL The emission of radiant energy during a transition from an excited electronic state of an atom, molecule, or ion to a lower electronic state (fluorescence or phosphorescence, or both), where the spectrum of the excitation source is in the ultraviolet (UV) or visible region of the electromagnetic spectrum, or both, and the spectrum of the emitted energy is in the far red or infrared (IR) region of the electromagnetic spectrum. (ANSI/ASB Std 035)

As related to the polymerase chain reaction (PCR), any substance that interferes with or prevents the synthesis of DNA during the amplification process.

Written movement at the beginning of a character. (Also known as beginning or commencement stroke.)

The fundamental training associated with detector canine training which consists of, but not limited to: bonding/relationship building, obedience, basic odor/scent discrimination, and basic search techniques.

A precise recipe or set of ingredients and their quantities that the manufacturer specifies for the final ink product. These ingredients are colorants (dyes and pigments) and components (volatile solvents, resins, etc.). (SWGDOC M01)

A non-impact printing method in which the image is formed by projecting droplets of a liquid or solid printing medium onto a substrate.

An organized collection of reference samples of inks and related materials. (SWGDOC M02)

A ribbon composed of a supporting substrate of film, fabric, or paper and a coating or impregnation of a coloring material. The coloring material is of such nature that it will transfer in part or entirely to a copy sheet at the point of pressure contact. (ASTM F221)

A process recording footwear/tiretrack impressions on white chemically treated paper

An XML package described by a schema is called an instance document. If a documentsatisfies all the constraints specified by the schema, it is considered to be schema-valid.

The innate tendency to react in specific ways in specific circumstances. Behaviors that are not taught, and are stereotypical in action and similar in all members of a species.

See canine trainer.

See operant conditioning.

A determination made by an FDE that the material to be examined does not contain enough information for an examination to be conducted. This may be due to the amount, complexity, comparability, or line, reproduction or writing quality of the material. In many instances, FDEs report an inconclusive opinion, explaining limitations/insufficiency, rather than reporting an insufficient opinion. (NIST HF)

The INTERPOL application profile of the ANSI/NIST-ITL standard, developed by theINTERPOL AFIS Expert Group.

Process in which the image areas are below the non-image areas of the plate, resulting in raised printing on the substrate.

Comparison between two or more items to determine whether or not they share a common source.

The extent to which different observers obtain the same result when measuring the same behavior.

The portion of the palm along the base of the fingers.

Any reaction to an odor/scent, which may include: (1) A noticeable, readable, physical change in behavior in a detector canine during the search when the canine reacts to (i.e., is interested in) an odor/scent. (2) Pattern of behavior following the canine's initial reaction to a trained odor/scent when the canine displays motivation to remain at or trace the trained odor/scent to its source. (See change of behavior.)

Any person, entity, or organization, including their representatives, with statutory obligations or whose legal rights or interests may be affected by the investigation of a specific incident.

pattern observed during conoscopic observation of an anisotropic material which consists of a combination of extinction positions and interference colors corresponding to the full cone of directions by which the sample is illuminated. 

DISCUSSION—Conoscopic observations are typically made by insert- ing a Bertrand lens into the body tube or by removing an eyepiece and viewing down the body tube.

Experiments performed to determine substances that inhibit or affect the intensity of the assay signal.

Non-targeted substances (i.e., matrix components, other drugs and metabolites, internal standard, impurities) which may impact the ability to detect, identify, or quantitate a targeted analyte.
