Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder .
Chemical Society Reviews publishes "Tutorial reviews" and "Critical reviews". The former are written to be of relevance both to the general research chemist who is new to the field, as well as the expert, whereas the latter aim to provide a deeper understanding of the topic in hand, but retain their accessibility through an introduction written for the general reader.
The Annual Review of Analytical Chemistry is a peer-reviewed academic journal that publishes an annual volume of review articles relevant to analytical chemistry. It was established in 2008 and is published by Annual Reviews. As of 2023, it is being published as open access, under the Subscribe to Open model. [2]
[citation needed] A systematic review of clinical trials concluded that a previous history of PEP or pancreatitis significantly increases the risk for PEP to 17.8% and to 5.5% respectively. [20] [21] Intestinal perforation is a risk of any gastroenterologic endoscopic procedure, and is an additional risk if a sphincterotomy is performed.
The editorial committee considered changing the name of the journal in the 1980s to the Annual Review of Physical Chemistry and Chemical Physics, though decided against it by 1988. [7] In addition to publishing reviews about physical chemistry, many volumes contain a prefatory chapter with an informal review of a chemist or institution. [8]
Here, 1 / f eq is an integer value. Each solute can produce one or more equivalents of reactive species when dissolved. In redox reactions, the equivalence factor describes the number of electrons that an oxidizing or reducing agent can accept or donate. Here, 1 / f eq can have a fractional (non-integer) value.
A graphing calculator is a class of hand-held calculator that is capable of plotting graphs and solving complex functions. While there are several companies that manufacture models of graphing calculators, Hewlett-Packard is a major manufacturer. The following table compares general and technical information for Hewlett-Packard graphing ...
HP has never made another calculator specifically for programmers, [2] but has incorporated many of the HP-16C's functions in later scientific and graphing calculators, for example the HP-42S (1988) and its successors. Like many other vintage HP calculators, the HP-16C is now highly sought-after by collectors. [14]
