Albatros L.66. The Albatros L.66 was a simple, low powered, two seat sports and training parasol wing monoplane, built in Germany in the mid-1920s.

Design and development
The L.66 was intended to be a low cost, easy maintenance two-seater. Thus a low power engine was required and the prototype was fitted with a  Haacke HFM-2 flat twin, though other engines could be used. It was a cantilever parasol monoplane with an aerodynamically thick airfoil section wing, which had a simple, rectangular plan and significant dihedral.  The wing was a wooden structure with two spars, the ailerons mounted directly to a rounded groove in the rear spar.  It was linked to the upper fuselage by a rather complicated set of struts.

Traditionally, Albatros had constructed fuselages with wood frames, but the L.66 marked a departure, with a welded steel tube longeron and strut framework covered with fabric. The sides were flat and almost airfoil-shaped, with a blunt, rounded nose and taper aft. The nose-mounted engine, driving a two-blade propeller, was raised above the fuselage with a fairing behind it, enclosing the oil tank and with the instrument panel attached to its rear. The fuel tank was in the wing centre section, feeding the engine by gravity. Further aft, pilot and passenger sat side by side in the  wide fuselage; tandem controls could be fitted if required. The empennage was simple in shape and action as there were no fixed surfaces, only an all-moving rudder and elevator. Both control surfaces were balanced.  The conventional undercarriage was also very simple, with the mainwheels attached to a single axle which passed through the fuselage, sitting the L.66 close to the ground.  The tailskid was linked to the rudder for steering on the ground

Operational history

The first L.66 was flying in mid-1924 with the Haacke engine. In all ten were built.

Variants
L.66 Haacke engine.
L.66a Slightly larger and heavier, with Stahlwerk Mark St.M3 or Anzani engine.
L.66c
L.67Lighter version, Bristol Cherub or Anzani engine. Two built.

Darwin Aviation Museum. The Darwin Aviation Museum, previously known as the Australian Aviation Heritage Centre, displays aircraft and aircraft engines of relevance to the Northern Territory and aviation in Australia generally. It is located in the Darwin suburb of Winnellie.

History 
The museum's origins can be traced to 1976 when a group of enthusiasts sought to preserve aviation relics after the destruction of Cyclone Tracy. It was later broadened to include the documentation of World War II aircraft crash sites and the preservation of aviation relics related to the defence of Darwin during World War II. The museum was first opened to the public in 1988. In the late 1980s, the Society negotiated with the United States Air Force (USAF) and the Northern Territory Government to obtain a surplus USAF Boeing B-52 Stratofortress bomber and to build a museum to house and display the aircraft. 

In June 1990, the new Darwin Aviation Museum opened. In 2011, the museum was considered as a display location for one of two Mi-24s confiscated by the Department of Defence in 1997. Due to the presence of asbestos in the airframes, the proposal was dropped. In 2018, the museum acquired a P-3C and looked into expanding their hangar space to house it.

Collection 

The museum has on display a Boeing B-52G bomber. It is on permanent loan from the United States Air Force and is one of only three on public display in the world outside the US. There is a bomb fragment dating from a WWII air raid on Darwin.

Kingwood Tunnel. The Kingwood Tunnel, near Tunnelton, West Virginia, was built between 1849 and 1852 by the Baltimore and Ohio Railroad on its main line between Baltimore, Maryland and Wheeling, West Virginia, under the supervision of B&O chief engineer Benjamin Henry Latrobe, II. At the time of its completion the  tunnel was the longest tunnel in the United States until it was surpassed by the Blue Ridge Tunnel in 1858.

Workers were recruited from coal mines in the area to excavate the tunnel. Three vertical shafts were established to allow work in two directions from each shaft, and from either end, using eight headings. The shafts were about  deep and measured about  by . The hoists were operated using horses. The tunneling operations used black powder as explosive. Dangerous rock conditions at the east end of the tunnel and accidents with black powder caused many casualties, with a total of about 30 deaths and 300 injuries in the excavation of the Kingwood Tunnel and the contemporaneous Board Tree Tunnel on the same line.

Although the tunnel itself was completed in 1852, track was not laid, due to problems with the east entrance. A temporary switchback track, requiring reversal at each stage, was built to provide service until the tunnel was finished. Work began in 1854 on an arched liner using prefabricated sections of iron, faced with stone against the eventual deterioration of the iron liners.  of this system were used at the east end, and another  of the tunnel were lined with brick. Lining work, followed by track laying, was completed in 1858. It was completed with two tracks, but the increasing size of rolling stock necessitated a conversion to single track after 1865. Grouting and underpinning work was required in 1889 through the entire length of the tunnel, and additional brick lining was later installed in the section with iron liners.

The single-track tunnel was bypassed by a double-track tunnel in 1912. The new tunnel's east portal incorporated the old east portal, and the original tunnel continued in service. The old bore was abandoned and sealed in 1962.

Board Tree Tunnel. The Board Tree Tunnel, near Littleton, West Virginia, was built between 1851 and 1858 by the Baltimore and Ohio Railroad on its main line between Baltimore, Maryland, and Wheeling, West Virginia, under the supervision of B&O chief engineer Benjamin Henry Latrobe, II. The   tunnel used a segmental cast iron lining system pioneered on the contemporaneous Kingwood Tunnel on the same line.

Workers were recruited from coal mines in the area to excavate the tunnel. The tunneling operations used black powder as explosive. About 30 deaths and 300 injuries occurred in the excavation of the Board Tree and Kingwood tunnels. The tunnel is now abandoned.

OFW OK-15. The OFW OK-15 was a 1950s Austrian two-seat light aircraft. Designed by Otto Kauba and built by the Österreichische Flugzeugwerke GmbH (OFW) at Wiener Neustadt, it was the first aircraft to be designed and built in Austria for 20 years.

Design and development

The OK-15 was a light sports monoplane of conventional design with a low wing, enclosed side-by-side two-seat cockpit and fixed undercarriage with tailwheel. It was manufactured using traditional materials of metal, wood and fabric, and stressed for aerobatics. It had a span of  and length .

The aircraft was powered by a  Walter Minor 4-III piston engine, giving it an estimated cruise speed of .

The only prototype was registered OE-VAM and first flown on 16 July 1956. Subsequent fight tests showed its handling to be unsatisfactory and it was not put into production.

PIEZO2. Piezo-type mechanosensitive ion channel component 2 is a protein that in humans is encoded by the PIEZO2 gene. It has a homotrimeric structure, with three blades curving into a nano-dome, with a diameter of 28 nanometers.

Function 

Piezos are large transmembrane proteins conserved among various species, all having between 24 and 36 predicted transmembrane domains. 'Piezo' comes from the Greek 'piesi,' meaning 'pressure.' The PIEZO2 protein has a role in rapidly adapting mechanically activated (MA) currents in somatosensory neurons. Its structure is resolved via a mouse version in 2019, showing the predicted homotrimeric propeller.

PIEZO2 is typically found in cell types that respond to physical touch, such as Merkel cells, and is thought to regulate light touch response.

Pathology 
 Gain-of-function mutations in the mechanically activated ion channel PIEZO2 cause a subtype of Distal Arthrogryposis.
 Mice without PIEZO2 in their proprioceptive neurons show uncoordinated body movements, indicating that PIEZO2 plays a role in mammalian proprioception.
 PIEZO2 mutations link Gordon syndrome (distal arthrogryposis type 3), Marden-Walker syndrome and Arthrogryposis (Distal Arthrogryposis Type 5).

Karol Pollak. Karol Franciszek Pollak (15 November 1859 – 17 December 1928) was a Polish electrical engineer, inventor and businessman.

Early life 
Karol Pollak was born in Sanok, Kingdom of Galicia and Lodomeria, part of the Austrian Empire. His father was Karol Pollak (1818–80), who was a printer, bookseller and publisher. The younger Karol worked as an electrician in his youth and showed great technical skills in it. In 1883 he was employed in the laboratory of a British company "The Patent Utilisation Co". He designed and recorded his first patents during this period. In 1885 he studied electrical engineering at the Royal Polytechnic University in Charlottenburg.

Activity 
In Berlin, Pollak ran the electrical equipment factory "G. Wehr Telegraphen-Bau-Anstalt". Later he returned to Britain to commercialize his patents, which were released under the anglicised version of his name, "Charles Pollak". In 1886, he became the director of a Paris company of electric tramways of his design. In the meantime he worked on the design of the electrochemical cell. He was very successful in this and became well-known for it. Later he founded battery factories in Frankfurt, (Germany) and Liesing, Austria. Many battery manufacturers have licensed his designs.

In 1899 he founded his own laboratory and proceeded with further research. He obtained 98 patents on his inventions.

In 1922 he returned to Poland, where a year later he founded a factory in Biała, which exists to the present day. The company started under the name of Polskie Towarzystwo Akumulatorowe and was co-founded by professor and the president of Poland, Ignacy Mościcki. However, Pollak was the first president of this company.

Pollak is sometimes referred to as the Edison of Poland. In 1925 he received the title Doctor Honoris Causa from Warsaw University of Technology.

Most important inventions 

His numerous inventions also cover other areas, among them: electric motors, a color printing device, and a type of microphone. His main activity was related to chemical sources of energy – galvanic cells and batteries. He obtained a patent for manufacturing lead-acid batteries.

Pollak also designed commutator and electrolytic rectifiers. In 1895 he was the first to suggest the use of full bridge diode rectification circuits. In 1896, Pollak invented the electrolytic capacitor

Caudron G.2. The Caudron G.2 was a single-engined French biplane built by Caudron, used in World War I as a reconnaissance aircraft and trainer.

Development
The outbreak of World War I precipitated the need for military applications of the successful Caudron Type G, leading to the creation of the G.2. The Caudron G.2 had a short crew nacelle, with a single engine in the nose of the nacelle, and an open tailboom truss. It was of sesquiplane layout, and used wing warping for lateral control. The wings of the Caudron had scalloped trailing edges that were to become a trademark of the aircraft.

Operational history
Ten Caudron G.2s were produced, with five being assigned to Escadrille Caudron Monoplace 39, four being delivered to the Australian Flying Corps, and one going to the Royal Naval Air Service.
