MEMS M-52/60
The MEMS M-52/60 is a submachine gun of Argentine origin manufactured by Miguel Enrique Manzo Sal (MEMS). It is chambered in the 9×19mm round and fed from a 40-round magazine inserted in the forward pistol grip.

Microelectromechanical systems
Microelectromechanical systems (MEMS, also written as micro-electro-mechanical, MicroElectroMechanical or microelectronic and microelectromechanical systems and the related micromechatronics) is the technology of very small devices; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as micromachines in Japan, or micro systems technology (MST) in Europe.
MEMS are separate and distinct from the hypothetical vision of molecular nanotechnology or molecular electronics. MEMS are made up of components between 1 to 100 micrometres in size (i.e. 0.001 to 0.1 mm), and MEMS devices generally range in size from 20 micrometres to a millimetre (i.e. 0.02 to 1.0 mm). They usually consist of a central unit that processes data (the microprocessor) and several components that interact with the surroundings such as microsensors. At these size scales, the standard constructs of classical physics are not always useful. Because of the large surface area to volume ratio of MEMS, surface effects such as electrostatics and wetting dominate over volume effects such as inertia or thermal mass.

M-52 (Michigan highway)
M-52 is a north–south state trunkline highway in the US state of Michigan. The southern terminus is on the Ohio border, where it continues as State Route 109 (SR 109). The highway passes through communities like Adrian, where it intersects US Highway 223 (US 223), Chelsea and Webberville along its 127.3-mile-long (204.9 km) course. It crosses some major rivers, including the River Raisin and the Shiawassee. The section of the highway between M-50 and Manchester was built as a limited-access highway. M-52's northern terminus is at M-46, nine miles (14 km) west of Saginaw.
Adrian previously converted their downtown streets to one-way traffic between 1950 and 1973. The traffic pattern created an unusual arrangement in the routings of the two state highways downtown. Southbound M-52 followed Winter Street, which also carried both eastbound and westbound directions of the US 223 business loop. These streets carried both highways around the downtown business district in this arrangement until November 2009.
Mosin–Nagant
The Mosin–Nagant (Russian: Винтовка Мосина, ISO 9: Vintovka Mosina) is a five-shot, bolt-action, internal magazine-fed, military rifle, developed by the Imperial Russian Army in 1882–91, and used by the armed forces of the Russian Empire, the Soviet Union and various other nations. It is one of the most mass-produced military bolt-action rifles in history with over 37 million units produced since its conception in 1891, and in spite of its age it has shown up in various conflicts around the world even up to the modern day, being plentiful, cheap, rugged, simple to use, and effective, much like the AK-47 and its variants.
History
Initial design and tests
During the Russo-Ottoman War of 1877–1878, Russian troops armed mostly with Berdan single-shot rifles suffered heavy casualties against Turkish troops equipped with Winchester repeating rifles, notably at the bloody Siege of Pleven. This showed Russian commanders the need to modernize the Imperial Army.
In 1889, three rifles were submitted for evaluation: Captain Sergei Ivanovich Mosin of the Imperial Army submitted his "3-line" caliber (.30 cal, 7.62mm) rifle; Belgian designer Léon Nagant submitted a "3.5-line" (.35 caliber, 9mm) design; and a Captain Zinoviev submitted another "3-line" design. (One "line" = 1/10".)
