A letter, which when alone, constitutes a word, such as "I" and "A". Also, a letter which is not connected to the remaining letters of a word, such as the capital letter in some names.

(1) A handler technique by which the handler will present productive area to the canine, usually by pointing or hand and arm sweeps. (2) Used to search a particular area in more detail or when a canine may have walked by to prompt the canine to search in a particular direction. (3) Used to prompt a canine to search high and low productive areas.

(1) sensing the existence of a fire, especially by a detector from one or more products of the fire, such as smoke, heat, infrared radiation, and the like. (2) the act or process of discovering and locating a fire.

A canine trained to detect and alert to the presence of certain scents or odors for which it has been trained. May be referred to as a law enforcement or search and rescue service canine, which is not to be confused with canines covered by the Americans with Disabilities Act (ADA).

Propagation of a combustion zone at a velocity greater than the speed of sound in the unreacted medium. [68, 2018]

Intervals in the morphologic appearance of teeth as the crown or root mature.

The acquisition of test data and determination of conditions and limitations of a new methodology.

The acquisition of test data and determination of conditions and limitations of a new methodology; this generally occurs while the conditions and parameters are being worked out prior to the establishment of a defined assay, procedure or product. Internal validation studies follow developmental validation studies.

The acquisition and evaluation of test data for the determination of the conditions and/or limitations under which a novel method will achieve consistent results.

The acquisition of test data and determination of conditions and limitations of a new methodology; this generally occurs while the conditions and parameters are being worked out prior to the establishment of a defined assay, procedure or product. Internal validation studies typically follow developmental validation studies.

The accumulation of test data to demonstrate that established parameters, software settings, formulae, algorithms and mathematical functions perform as expected. Developmental validation should also demonstrate any known limitations of the system. Developmental validation may be conducted outside the laboratory planning to use it (i.e., by the manufacturer, developer, or other testing laboratory) and will precede any internal validations

(Replacing worming) is the giving of an anthelmintic drug (a wormer, dewormer, or drench) to a human or animal to rid them of helminths parasites, such as roundworm, flukes and tapeworm.

Those dots, lines, and swoops that appear above, below, and occasionally even beside certain letters in words. The purpose of diacritical marks is to change the sound of the individual letter they are marking or to change the meaning of an entire word by changing which syllable is accented. Often incorrectly used to describe such characteristics as the "i" and "j" dot. Déjà vu.

Radiographs, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), ultrasound, and other diagnostic modalities used to assess and document condition, injury, or disease processes.

A MS or MS/MS molecular ion or fragment ion whose presence and abundance are characteristic of the targeted analyte.

A MS or MS/MS molecular ion or fragment ion whose presence and relative abundance are characteristic of the targeted analyte.

MS or MS/MS molecular ion or fragment ion whose presence and relative abundance are characteristic of the targeted analyte

A slanting stroke, as in the center stroke of the printed capital "N".

A list giving the start and stop times of speech segments within the voice signal,pertaining to the subject of the record. Diarization of segments from multiple speakersrequires multiple Type-11 records, one for each speaker. These multiple Type-11records may be contained in a single transaction, as long as the transaction is focusedupon a single subject.

A filter with two transmission bands. These bands are usually widely separated, and can be of significantly different size. (SWGDOC M01)

Nonimpact printing technique in which specially treated paper consisting of a conductive base layer coated with a nonconductive thermoplastic material is used to hold an electric charge usually applied directly by a set of electrode styli. The electric charge corresponds to the latent image of the original. Following the charging step, the paper is imaged by a toner system similar to that of electrostatic copying devices. This technique is sometimes called electrographic, and is currently used on general purpose non-impact printers, plotting and facsimile devices. (SWGDOC E05)

Consistent, repeated dissimilarity in a structural or other characteristic or feature, that cannot be reasonably explained as variation or deviation from natural variation of a single source or class.

A process through which all possible causes of a skeletal or dental anomaly/abnormality are considered. Through a careful process of elimination, only the most likely causes remain to aid in the identification of the pathological or anomalous condition(s) of the skeleton.

A method of DNA extraction where sperm and non-sperm cells are digested separately based on the different composition of the cell membranes resulting in the generation of a sperm fraction and a non-sperm cell fraction.

A gas, vapor, dust, particulate, aerosol, mist, fog, or hybrid mixture of these, suspended in the atmosphere, which is capable of being ignited and propagating a flame front.

Diffusion by reflection in which, on the macroscopic scale, there is no regular reflection. (CIE S 017/E:2011 ILV)

A flame in which fuel and air mix or diffuse together at the region of combustion.

The measure of how much of the nutrient in a food the canine can extract and absorb.

An image that is represented by discrete numerical values organized in a two-dimensional array; when viewed on a monitor, projected image or printed on paper, it appears similar to a photograph. (SWGIT/SWGDE)

Any activity that transforms a digital image. (SWGDOC E03) (ANSI/ASB Std 035)

A method of printing from a digital-based image directly to a variety of media.

A representative value of a signal at a chosen instant, derived from a portion of thatsignal. From the Vocabulary of Digital Transmission and Multiplexing, and PulseCode Modulation (PCM) Terms, ITU-T Recommendation G.701 (March, 1993)
