In the Republic of Ireland, laws against metal detecting are very strict: it is illegal to use a detection device to search for archaeological objects anywhere within the State or its territorial seas without the prior written consent of the Minister for Culture, Heritage and the Gaeltacht, and it is illegal to promote the sale or use of ...
The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. [1] Infrared thermometers , can also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux.
According to this report, the device detected hepatitis C with high specificity and sensitivity. [2] The device was said to compare the received electromagnetic signal from a patient to the ideal signal emitted by a specific part of the HCV RNA genome that had been measured in a laboratory and stored on the device. If those signals agreed, the ...
The position of letters in words and the position of suffix morphemes have an influence on word identification, letter detection, and the missing letter effect in texts. [20] [21] [22] The letters at the start and end of words, or the first and last letter of a word, contribute to how people read and recognize words. [21]
The electron capture detector is used for detecting electron-absorbing components (high electronegativity) such as halogenated compounds in the output stream of a gas chromatograph. The ECD uses a radioactive beta particle (electron) emitter in conjunction with a so-called makeup gas flowing through the detector chamber.
The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a distributed computer system. As a result, the failure detector was invented because of the need for detecting errors in the massive information transaction in distributed computing systems.
In its basic form, an NLJD can also detect things that are not themselves electronic in nature, so the use of the device requires a modicum of skill and experience. For example, a rusty nail inside a wall can give a false positive. For this reason, most modern NLJDs examine the ratio between the second and the third harmonic of the illumination ...
The term NO x represents several forms of nitrogen oxides such as NO (nitric oxide), NO 2 (nitrogen dioxide) and N 2 O (nitrous oxide, also known as laughing gas).In a gasoline engine, NO is the most common form of NO x at around 93%, while NO 2 is around 5% and the rest is N 2 O.
