The WI-38 cell line stemmed from earlier work by Hayflick growing human cell cultures. [2]In the early 1960s, Hayflick and his colleague Paul Moorhead at the Wistar Institute in Philadelphia, Pennsylvania discovered that when normal human cells were stored in a freezer, the cells remembered the doubling level at which they were stored and, when reconstituted, began to divide from that level to ...
They were called a 5-in-1 blanks, because, when they were originally introduced, they could be fired in the five different firearms commonly used in Hollywood Westerns, namely .38-40 and .44-40 Winchester lever-action rifles and .38-40 Winchester, .44-40 Winchester, and .45 Colt single-action revolvers. 5-in-1 blanks are also called a 3-in-1 ...
MRC-5 (Medical Research Council cell strain 5) is a diploid cell culture line composed of fibroblasts, originally developed from the lung tissue of a 14-week-old aborted white male fetus. [ 1 ] [ 2 ] The cell line was isolated by J.P. Jacobs and colleagues in September 1966 from the seventh population doubling of the original strain, and MRC-5 ...
MRC made a run of special oversized short action length, Winchester Short Magnum (WSM) actions based on their 1999 action, offered with custom serial numbers. The actions were cast by Sturm Ruger, production machined by Smith & Wesson and final machined then finished by MRC. The pre-production order cost of the SS action was US$350.00
The Lockheed Martin Mk 70 Mod 1 is a containerized system containing four strike-length cells from the Mark 41 Vertical Launching System mounted in the footprint of a 40-foot (12 m) ISO container. [4] In addition to the Typhon system, the Mk 70 Mod 1 has been tested aboard ship on USS Savannah (LCS-28). [14]
The WI-38 cell strain he developed at the Institute with Paul S. Moorhead, Ph.D., became the substrate for the production of many human virus vaccines. [ 25 ] Helen Dean King , Ph.D.: a biologist and the first woman research professor at Wistar and one of the first in the U.S. [ 26 ] A faculty member from 1909 to 1950, Dr. King researched the ...
The .38-55 Winchester / 9.6x53mmR cartridge (actually .3775 caliber), also known as the .38-55 WCF and the .38-55 Ballard, [4] is a centerfire rifle cartridge. It was based on an earlier cartridge called the .38-50 Ballard Everlasting that was introduced in 1876 by the Ballard Rifle & Cartridge Company .
An old .38-40 Winchester sample. It is unclear why this cartridge was introduced, as it is very similar to the .44-40 from which it was derived. It has approximately 110 ft⋅lbf (150 J) less muzzle energy, and has a muzzle velocity about 110 ft/s (34 m/s) less than the .44-40.
