The RTI is the rounded temperature in degrees C, at which the properties of B have decreased to 50 percent of their initial value in about the same amount of time (correlation time) than it takes for A at its own RTI value. A maximum correlation time of 60.000 hours is considered acceptable for many electrical applications, however it may also ...
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.
A standard test image is a digital image file used across different institutions to test image processing and image compression algorithms. By using the same standard test images, different labs are able to compare results, both visually and quantitatively.
A "relative fluorescence unit" is a unit of measurement used in analysis which employs fluorescence detection. [1] Fluorescence is detected using a charge-coupled device (CCD) array, when the labeled fragments, which are separated within a capillary by using electrophoresis, are energized by laser light and travel across the detection window.
NPU terminology (NPU; Nomenclature for Properties and Units) is a patient centered clinical laboratory terminology for use in the clinical laboratory sciences.Its function is to enable results of clinical laboratory examinations to be used safely across technology, time and geography.
Temperature programmed desorption (TPD) is the method of observing desorbed molecules from a surface when the surface temperature is increased. When experiments are performed using well-defined surfaces of single-crystalline samples in a continuously pumped ultra-high vacuum (UHV) chamber, then this experimental technique is often also referred to as thermal desorption spectroscopy or thermal ...
Temperature determines the statistical occupation of the microstates of the ensemble. The microscopic definition of temperature is only meaningful in the thermodynamic limit, meaning for large ensembles of states or particles, to fulfill the requirements of the statistical model. Kinetic energy is also considered as a component of thermal energy.
