P22 (type Foundry)
P22 Type Foundry is a digital type foundry and letterpress printing studio based in Rochester, New York. The company was created in 1994 in Buffalo, New York by co-founders Richard Kegler and Carima El-Behairy. The company is best known for its type designs, which have appeared in films (e.g. Harry Potter, Suburbicon) and on commercial products (e.g. Trader Joe's, Founders Brewing Co.). The P22 Type Foundry retail font collection specializes in historical letterforms inspired by art, history, and science that otherwise have never been available previously in digital form. P22 works with museums and foundations to ensure the development of accurate historical typefaces, and with private clients to create custom bespoke fonts. History The name P22 has no specific significance and was used by founder Richard Kegler prior to the type foundry as a label for various art projects including an ambitious mail art correspondence. Once P22 started developing fonts, they began to sell th ...

Curtiss XP-22 Hawk
The Curtiss XP-22 Hawk was a 1930s American experimental biplane fighter built by Curtiss for evaluation by the United States Army Air Service. Design and development In 1929, the AAC ordered three P-11 Hawks for testing of the 600 hp (447 kW) H-1640 Chieftain engine. This engine proved a failure, and before completion, one of the three was converted to use a 9-cylinder 575 hp (429 kW) Cyclone, being completed as the YP-20. Testing with the R-1820 was prolonged, so the Army acquired another of the three P-11s, instead. This became the XP-22. A number of changes were made for installing the 700 hp (520 kW) Curtiss V-1570 Conqueror engine. The radiator was relocated, a new cowl was fitted, and the tail was given more fin and less rudder area, and featured a steerable tailwheel, rather than the original skid. For these changes, Curtiss charged only US$1.Fitzsimons 1978, p. 1255. During testing, the XP-22 underwent a number of alterations and impr ...

Papyrus 22
Papyrus 22, designated by (in the Gregory-Aland numbering of New Testament manuscripts), is an early copy of the New Testament in Greek. It is a papyrus manuscript of the Gospel of John, only containing extant John 15:25-16:2, 21–32. Using the study of comparative writings styles, (palaeography), the manuscript has been dated to the early 3rd century CE. It is the only identified New Testament papyrus to have been written originally as a roll; not a codex or re-using the back of a scroll. Description The text was written in two consecutive columns on a roll. The reverse side is blank. The manuscript employs conventional Nomina Sacra: . The text contains no punctuation marks.B. P. Grenfell & A. S. Hunt, ''Oxyrynchus Papyri'' X, (London 1914), p. 14. The Greek text of this codex is considered a representative of the Alexandrian text-type. Aland described it as a normal text and placed it in Category I. This manuscript displays an independent text. Coincidences with th ...

Salmonella Virus P22
''Salmonella virus P22'' is a bacteriophage in the ''Podoviridae'' family that infects ''Salmonella typhimurium''. Like many phages, it has been used in molecular biology to induce mutations in cultured bacteria and to introduce foreign genetic material. P22 has been used in generalized transduction and is an important tool for investigating ''Salmonella'' genetics. Morphology, classification and relatives P22 shares many similarities in genetic structure and regulation with bacteriophage λ. It is a temperate double stranded DNA phage as well as a lambdoid phage since it carries control of gene expression regions and early operons similar to those of bacteriophage λ. However, the genes which encode proteins that build the virion are different from those of bacteriophage λ. P22 has a 60 nm diameter icosahedral (T=7) virion head and a short tail. This virion morphology puts P22 in the formal ''Podoviridae'' group. Traditionally, P22 is associated with viruses w ...

Walther P22
The P22 is a semi-automatic pistol chambered for .22 LR (5.6 mm) rimfire ammunition. Manufactured by Carl Walther GmbH Sportwaffen, it was introduced in 2002. Operation The P22 may be fired double action at about , and operates as a single action with slightly more than . The P22 operates by blowback where pressure generated by a firing cartridge is countered by a combination of the inertial weight of the slide assembly and the force of the recoil spring. The action will not open until the projectile has left the barrel and the pressures have dropped to safe levels. The gun will not cycle efficiently unless high velocity .22 (5.6 mm) rounds are used. Criminal use A Walther P22 was one of the weapons used in the 2007 Virginia Tech shooting. A Walther P22 was the weapon used in the 2008 Kauhajoki school shooting.

Graniteville Train Crash
The Graniteville train crash was an American rail disaster that occurred on January 6, 2005, in Graniteville, South Carolina. At roughly 2:40 am EST, two Norfolk Southern trains collided near the Avondale Mills plant in Graniteville. Nine people were killed and over 250 people were treated for toxic chlorine exposure. The accident was determined to be caused by a misaligned railroad switch. Accident On January 5, 2005, NS local train P22 (lead by GP59 #4622) began its daily operation. The regularly assigned conductor and engineer were both off duty on January 5, and the jobs were filled for the day from a list of available standby employees. At the end of their scheduled run, train P22's crew parked the train on a siding near the Avondale Mills plant. The train crew contacted the local train dispatcher at 7:53PM and 7:54PM to clear two track warrants that were protecting train P22's use of the tracks. Although the railroad switch for the Avondale Mills siding was supposed to ...
