P0 Protein
Myelin protein zero (P0, MPZ) is a single membrane glycoprotein which in humans is encoded by the ''MPZ'' gene. P0 is a major structural component of the myelin sheath in the peripheral nervous system (PNS). Myelin protein zero is expressed by Schwann cells and accounts for over 50% of all proteins in the peripheral nervous system, making it the most common protein expressed in the PNS. Mutations in myelin protein zero can cause myelin deficiency and are associated with neuropathies like Charcot–Marie–Tooth disease and Dejerine–Sottas disease. Structure In humans, the gene that encodes myelin protein zero is located on chromosome 1 near the Duffy Locus or the Duffy Antigen/Chemokine Receptor. The gene is about 7,000 bases long and is divided into 6 exons. In total, myelin protein zero is 219 amino acids long and has many basic amino acid residues. Myelin protein zero consists of an extracellular N-terminal domain (amino acids 1–124), a single transmembrane region (1 ...

Atmospheric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravi ...

Neutronium
Neutronium (sometimes shortened to neutrium, also referred to as neutrite) is a hypothetical substance composed purely of neutrons. The word was coined by scientist Andreas von Antropoff in 1926 (before the 1932 discovery of the neutron) for the hypothetical "element of atomic number zero" (with zero protons in its nucleus) that he placed at the head of the periodic table (denoted by -, or Nu). However, the meaning of the term has changed over time, and from the last half of the 20th century onward it has been also used to refer to extremely dense substances resembling the neutron-degenerate matter theorized to exist in the cores of neutron stars; hereinafter "''degenerate'' neutronium" will refer to this. In neutron stars Neutronium is used in popular physics literature to refer to the material present in the cores of neutron stars (stars which are too massive to be supported by electron degeneracy pressure and which collapse into a denser phase of matter). This term is very rar ...

Proflight Zambia
Proflight Zambia is an airline based in Lusaka, Zambia that serves the business community and tourism industry. It is a trading name of Proflight Commuter Services Ltd. Proflight Zambia operates the largest fleet of aircraft in Zambia, operating both scheduled and charter flights. The airline has been growing rapidly in recent years and is the largest airline in Zambia by routes served and fleet size. History Proflight Air Services was founded in 1991 by pilot Tony Irwin, formerly of Zambia Airways. On 30 June 2009 the airline was authorized by the Zambia Competition Commission to form an alliance with Zambezi Airlines. The airline was officially rebranded as Proflight Zambia in 2010. In March 2013 Proflight took delivery of its first jet aircraft, a Boeing 737-200, and later in 2013 began regional scheduled service to Lilongwe, Malawi, and Dar es Salaam, Tanzania, although the Boeing was returned to the lessor, Star Air Cargo, in 2014.
