[1] [2] Scutching can be done by hand or by a machine known as a scutcher. Hand scutching of flax is done with a wooden scutching knife and a small iron scraper . The end products of scutching flax are the long finer flax fibers called line, short coarser fibers called tow , and waste woody matter called shives .
The fecal immunochemical test (FIT) is a diagnostic technique that examines stool samples for traces of non-visible blood, which could potentially indicate conditions including bowel cancer. [1] Symptoms which could be caused by bowel cancer and suggest a FIT include a change in bowel habit, anaemia , unexplained weight loss, and abdominal pain .
Variations in the electrical conductivity and magnetic permeability of the test object, and the presence of defects causes a change in eddy current and a corresponding change in phase and amplitude that can be detected by measuring the impedance changes in the coil, which is a telltale sign of the presence of defects.

In electrical engineering, a dielectric withstand test (also pressure test, high potential test, hipot test, or insulation test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground.
This type of test is considered a diffusion test. [18] In agar and broth dilution methods, bacteria are placed in multiple small tubes with different concentrations of antibiotics. [14] Whether a bacterium is sensitive or not is determined by visual inspection or automatic optical methods, after a period of incubation. [5]
The Schick test, developed in 1913, [1] is a skin test used to determine whether or not a person is susceptible to diphtheria. [2] It was named after its inventor, Béla Schick (1877–1967), a Hungarian-born American pediatrician.
A test designed to identify biomarkers associated with autism just became available in most states. The test is meant to help physicians rule out autism in children who have higher likelihoods of it.
While in-circuit test is a very powerful tool for testing PCBs, it has these limitations: Parallel components can often only be tested as one component if the components are of the same type (i.e. two resistors); though different components in parallel may be testable using a sequence of different tests - e.g. a DC voltage measurement versus a measurement of AC injection current at a node.
