Comprehensive two-dimensional gas chromatography, or GC×GC, is a multidimensional gas chromatography technique that was originally described in 1984 by J. Calvin Giddings [1] and first successfully implemented in 1991 by John Phillips and his student Zaiyou Liu. [2] GC×GC utilizes two different columns with two different stationary phases. In ...
The baby-step giant-step algorithm could be used by an eavesdropper to derive the private key generated in the Diffie Hellman key exchange, when the modulus is a prime number that is not too large. If the modulus is not prime, the Pohlig–Hellman algorithm has a smaller algorithmic complexity, and potentially solves the same problem. [2]
In documentation and instructional design, tutorials are teaching-level documents that help the learner progress in skill and confidence. [7] Tutorials can take the form of a screen recording (), a written document (either online or downloadable), interactive tutorial, or an audio file, where a person will give step by step instructions on how to do something.
The comprehensive metabolic panel, or chemical screen (CMP; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, diabetic and parathyroid status, and electrolyte and fluid balance , but this type of screening has its limitations.
A test panel is a predetermined group of medical tests used in the diagnosis and treatment of disease.. Test panels (sometimes called profiles) are typically composed of individual laboratory tests which are related in some way: by the medical condition they are intended to help diagnose (cardiac risk panel), by the specimen type (complete blood count, CBC), by the tests most frequently ...
STEP was shown to lengthen the bowel from 105.2 ± 7.7 cm to 152.2 ± 8.3 cm. [2] STEP was first performed on a human patient, a two-year-old who had been born with gastroschisis, in 2003. [ 3 ] By 2010, it had been utilized by more than 20 hospitals, mostly in the United States. [ 4 ]
Cops are warning residents in rural South Carolina to shut their doors and windows after at least 43 monkeys escaped from a bio-research lab. The rhesus macaques slipped out of an Alpha Genesis ...
Multiple tests for specific blood components, such as a glucose test or a cholesterol test, are often grouped together into one test panel called a blood panel or blood work. Blood tests are often used in health care to determine physiological and biochemical states, such as disease , mineral content, pharmaceutical drug effectiveness, and ...
