The name of the travel reservation system is an abbreviation for "Semi-automated Business Research Environment", and was originally styled in all-capital letters as SABRE. [1] It was developed to automate the way American Airlines booked reservations. In the 1950s, American Airlines was facing a serious challenge in its ability to quickly ...
At 25 °C (77°F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at 25 °C are neutral (i.e. have the same concentration of H + ions as OH − ions, i.e. the same as pure water). The neutral value of the pH depends on the temperature and is lower than 7 if the temperature ...
Breaking Bad. Breaking Bad is an American crime drama television series created and produced by Vince Gilligan for AMC. Set and filmed in Albuquerque, New Mexico, the series follows Walter White ( Bryan Cranston ), an underpaid, dispirited high-school chemistry teacher struggling with a recent diagnosis of stage-three lung cancer.

Cross-domain solution. A cross-domain solution ( CDS) is an integrated information assurance system composed of specialized software, and sometimes hardware, that provides a controlled interface to manually or automatically enable and/or restrict the access or transfer of information between two or more security domains based on a predetermined ...
Silver nanoparticles can prevent bacteria from growing on or adhering to the surface. This can be especially useful in surgical settings where all surfaces in contact with the patient must be sterile. Silver nanoparticles can be incorporated on many types of surfaces including metals, plastic, and glass. [91]
The alkali–silica reaction ( ASR ), also commonly known as concrete cancer, [3] is a deleterious internal swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous ( i.e., non-crystalline) silica found in many common aggregates, given sufficient moisture.
The Heckman correction is a two-step M-estimator where the covariance matrix generated by OLS estimation of the second stage is inconsistent. [7] Correct standard errors and other statistics can be generated from an asymptotic approximation or by resampling, such as through a bootstrap. [8]
Semaglutide is an antidiabetic medication used for the treatment of type 2 diabetes and an anti-obesity medication used for long-term weight management. [19] [20] [21] It is a peptide similar to the hormone glucagon-like peptide-1 (GLP-1), modified with a side chain .
