Microleve Corsario. The Microleve Corsario () is a Brazilian amphibious ultralight flying boat that was designed and produced by Microleve of Rio de Janeiro. The aircraft was supplied as a kit for amateur construction.

The company appears to be out of business and the aircraft no longer available.

Design and development
The Corsario complies with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced parasol wing, a two-seats-in-side-by-side configuration enclosed cockpit, retractable conventional landing gear and a single engine in pusher configuration. The landing gear is manually retracted.

The aircraft fuselage and hull are made from composites. The Mark 5 version of the Corsario offered two alternative wings. An all-composite wing of  span could be ordered with two  fuel tanks fitted behind the seats in the fuselage or an aluminum tubing and aircraft fabric wing of similar span was available with two  wing mounted fuel tanks. Standard engines available from the factory were the  Rotax 582 or  Rotax 618 two-strokes or the  Rotax 912UL four-stroke powerplant.

King Road Tower. King Road Tower is a 34-story office tower that is located in Jeddah, Saudi Arabia. The tower contains the world largest advertisement LED screen, making it a valued landmark for the city. The screen measures almost 10,000 sq m and was designed, built and installed by French company Citiled, a world leader in tailor-made "Media Façade" projects for integration into architecture. 

Citiled was the company chosen by the project initiators in view of their expertise and their prestigious past achievements (e.g. the Agbar Tower designed by architect Jean Nouvel in Barcelona, the Hermes Building in Singapore, the Cocor luxury shopping centre in Bucharest, etc.).

21 floors on the north and south façades and 16 floors on the west façade have been equipped with LED screens developed by Citiled, i.e. a total of 9,850 sq m and more than 5 million LEDs, making this structure the largest Media Façade in the world installed on an inhabited building.

It took more than 6 months to produce the 10,000 sq metres of this media façade, occupying a team of around twenty engineers and craftsmen for three months during the project design phase and then 6 months for installation and testing.

Citiled uses patented technological innovations and was able to develop and implement systems that are almost transparent when mounted on the façades, guaranteeing daylight for the building's occupants and preserving visibility.

The project's main contractor was FADEN and MEP sub-contractor TECHNO - Technical Electromechanical Works Co. Ltd.

Rhenium(VII) sulfide. Rhenium(VII) sulfide is a chemical compound with the formula Re2S7. It has a complex structure, but can be synthesized from direct combination of the elements: 2Re{} + 7S ->[{}\atop\Delta] Re2S7Alternatively, rhenium(VII) oxide reacts with hydrogen sulfide in 4N HCl to the same end: Re2O7{} + 7H2S ->[{}\atop\Delta] Re2S7{} + 7H2O

The compound catalyses the reduction of nitric oxide to nitrous oxide and hydrogenation of double bonds.  In this regard, it unusually tolerates sulfur compounds, which poison noble metal catalysts.

Rhenium(VII) sulfide decomposes when heated.  In vacuum, it generates rhenium(IV) sulfide:

In air, the sulfide oxidizes to sulfur dioxide:

EtherCON. The EtherCON is a ruggedized and lockable connector for Ethernet over twisted pair wiring. It is manufactured by Neutrik and is designed for professional audio and stage lighting network applications.

Design
The design is modeled after the XLR connector with a circular hard metal shell and a locking latch. The cable connector is always male and is designed to fit over a standard 8P8C modular connector. The chassis connector is always female and has the standard form factor of an XLR panel connector.  The chassis connector may be mated with an EtherCON connector and a standard 8P8C plug.  The chassis connectors are rated for either Cat 5e, Cat 6 or 6A compatibility, with the Cat 5e and 6A models being cross-compatible. (The Cat 6 model utilizes a different shell design from the other models.) Neutrik makes two styles of the connector, one for assembly before the 8P8C plug is attached, and one that will fit over a pre-attached plug.

When sealing gaskets are used, EtherCON is capable of providing a waterproof cable connection for harsh environments.

Applications
EtherCON connectors are used on many audio over Ethernet and audio over IP products. EtherCON connectors are also used to transfer data across large LED displays in both indoor and outdoor settings.

North American Farms Airport. North American Farms Airport  is a private airport, located 5.6 miles east of Malone, Florida.

Overview
Opened in March 1992, the airport is used for crop dusting operations and the owner's private use.

History 
Originally constructed by the United States Army Air Forces in 1943 as one of four auxiliary airfields for the pilot training school at Marianna Army Airfield.  Its original designation was Bascom  Auxiliary Army Airfield #3. The airfield was constructed with two asphalt 5'000 foot runways, each with a parallel taxiway.   

The airfield was apparently unmanned, had no buildings nor any permanent units assigned. It was used for emergency and for touch-and-go landings as part of the pilot training school. With the end of World War II and the closure of Mariana AAF, the airfield was closed and abandoned.

With the reopening of Mariana AAF as Grahm Air Base in 1950 as a contract pilot training school,  Bascom was rehabilitated as an auxiliary airfield for Grahm (Grahm #1) and was used for emergency landings. It was closed again in 1961 with the final closure of Grahm AB and again abandoned.

Today, only a section of the north/south runway of the former airfield's runway is in use, the asphalt surface being in marginal condition. The remainder of the airfield has had either the asphalt and concrete removed with the east/west runway lying derelict. It is not open to any general aviation.

No. 1 School of Military Aeronautics. 
The No 1 School of Military Aeronautics was a World War I training school for the Royal Flying Corps (RFC), based in Reading, England. It was formed in 1915 as an instructors college - but expanded in 1916 into a full RFC training school. In 1917 technical skills were separated and moved to a nearby airfield, Coley Park, as the School of Technical Training. All training at the school was on the ground; ranging from theoretical subjects through to practical training (e.g. taxiing and artillery observation).

History
In December 1915 the RFC commandeered buildings belonging to the University of Reading, at first for the purpose of training flight instructors. On 27 October 1916 the school was expanded to include cadet pilot and observer training, and designated No 1 School of Military Aeronautics (at the same time, No 2 school was opened in Oxford). The school's headquarters were in Yeomanry House, while most of the lessons were taught at Wantage Hall (a recently built hall of residence belonging to the University). Practical classes were held in Upper Redlands Road and nearby playing fields.

The school provided preliminary training for cadets and taught theoretical aspects of flight; including map reading, gunnery and mechanics. A small airfield was established at nearby Coley Park in around 1917. Technical trades were split off from the flight school, as the School of Technical Training, which operated from a jam factory adjoining the airfield. In September 1917 technical training was consolidated at Halton Camp, although Coley Park appears to have remained open for the rest of the war.

Many of the instructors were veterans of the Western Front. Still young men, they often struggled to teach the cadets who were of a similar age. For the observers the school had a room mocked up for artillery observation: a light-studded map was painted onto the floor and a mock fuselage hung from the ceiling.

Trimethylene carbonate. Trimethylene carbonate, or 1,3-propylene carbonate, is a 6-membered cyclic carbonate ester. It is a colourless solid that upon heating or catalytic ring-opening converts to poly(trimethylene carbonate) (PTMC).  Such polymers are called aliphatic polycarbonates and are of interest for potential biomedical applications. An isomeric derivative is propylene carbonate, a colourless liquid that does not spontaneously polymerize.

Preparation
This compound may be prepared from 1,3-propanediol and ethyl chloroformate (a phosgene substitute), or from oxetane and carbon dioxide with an appropriate catalyst:

HOC3H6OH + ClCO2C2H5 → C3H6O2CO + C2H5OH + HCl
C3H6O + CO2 → C3H6O2CO

This cyclic carbonate undergoes ring-opening polymerization to give poly(trimethylene carbonate), abbreviated PTMC.

Medical devices
The polymer PTC is of commercial interest as a biodegradable polymer with biomedical applications. 
A block copolymer of glycolic acid and trimethylene carbonate (TMC) is the material of the Maxon suture, a monofilament resorbable suture which was introduced in the mid-1980s. The same material is used in other resorbable medical devices.

Louis Puissant. Louis Puissant (22 September 1769, in Le Châtelet-en-Brie – 10 January 1843, in Paris) was a French topographical engineer, geodesist, and mathematician.

He was appointed an officer in the corps of topographical engineers (ingénieurs géographes) of l'armée des Pyrénées occidentales in 1792 and then a professor in l’école centrale d'Agen in 1796. From October 1802 to August 1803, he was in charge of geodesic triangulations on the island of Elba and then in 1803–1804 in Lombardy. He was elected a member of l'Société Philomathique de Paris in 1810 and a member of l'Académie des sciences in 1828.

In addition to numerous scientific memoirs, he was the author of several books on geodesy and mathematics.

His marriage to Françoise Coutet produced a son, Louis (1793–1836), who graduated from l'École polytechnique.

Sau Mau Ping Memorial Park. Sau Mau Ping Memorial Park () is a park located in Sau Mau Ping, Kwun Tong District, Kowloon, Hong Kong. The park was built on the hillside between Tsui Ping Road, Hiu Kwong Street and Hiu Ming Street, in memorial to the deceased of the disastrous flooding on 18 June 1972 (also known as June 18 flooding, in Chinese: ), which took 71 lives when the hill slope adjacent to the park failed.

History
On 30 June 1972, the Land Development Planning Committee decided that the site of the landslide should be reserved for the construction of an open space to serve as a memorial rather than a school, for which the site had previously been earmarked. The collapsed slope was rebuilt with a gentler gradient and improved drainage infrastructure to ensure stability. The Urban Council originally planned to build a garden along with some recreational facilities on the site, including a badminton and basketball court. But owing to the gentler gradient, the reconstructed slope occupied more space than the previous one that collapsed and the recreational elements of the memorial were dropped in favour of a simpler garden.

The park was completed in 1976. A stairway and pathway climbs the slope and links up with Hiu Kwong Street and a rest garden. A 560-square-metre section of land next to Kwun Tong Maryknoll College was added to the memorial park in the early 1980s.

Femto-photography. Femto-photography is a technique for recording the propagation of ultrashort pulses of light through a scene at a very high speed (up to 1013 frames per second). A femto-photograph is equivalent to an optical impulse response of a scene and has also been denoted by terms such as a light-in-flight recording or transient image. Femto-photography of macroscopic objects was first demonstrated using a holographic process in the 1970s by Nils Abramsson at the Royal Institute of Technology (Sweden). A research team at the MIT Media Lab led by Ramesh Raskar, together with contributors from the Graphics and Imaging Lab at the Universidad de Zaragoza, Spain, more recently achieved a significant increase in image quality using a streak camera synchronized to a pulsed laser and modified to obtain 2D images instead of just a single scanline.

In their publications, Raskar's team claims to be able to capture exposures so short that light only traverses 0.6 mm (corresponding to 2 picoseconds, or 2 seconds) during the exposure period, a figure that is in agreement with the nominal resolution of the Hamamatsu streak camera model C5680, on which their experimental setup is based. Recordings taken using the setup have reached significant spread in the mainstream media, including a presentation by Raskar at TEDGlobal 2012. Furthermore, the team was able to demonstrate the reconstruction of unknown objects "around corners", i.e., outside the line of sight of light source and camera, from femto-photographs.

In 2013, researchers at the University of British Columbia demonstrated a computational technique that allows the extraction of transient images from time-of-flight sensor data without the need for ultrafast light sources or detectors.

Other uses of the term
Prior to the aforementioned work, the term "femto-photography" had been used for certain proposed procedures in experimental nuclear physics.

Tour Perret (Amiens). Tour Perret (English: Perret Tower) is a 29-storey,  residential skyscraper in Amiens, France. It has been described as France's first skyscraper, and was registered as a historic monument in 1975.

Its building was part of a large scale reconstruction project helmed by architect Auguste Perret in the Place Alphone-Fiquet neighborhood, which also involved a rebuild of the nearby railway station. The design phase started as early as 1942, following extensive damages suffered by downtown Amiens during World War II. Perret intended it as an office building before authorities overruled him.

Originally measuring 104 metres, Tour Perret was the highest, and the first 100-plus metre skyscraper built in France, although it was not the highest in Western Europe, as it has sometimes been written. The building actually fell slightly short of its intended height as its topmost part, a belfry adorned with a monumental clock, was never built due to delays and cost overruns.

In 2005, the tower was finally completed with a so-called Sablier de lumière (English: Hourglass of Light) designed by architect Thierry Van de Wyngaert. It is a cube made of 192 active glass panels whose transparency can be electrically adjusted, illuminated by twelve circular neon lamps which project different colors depending on the time of day. In 2017, the lighting system was redesigned and simplified for cost and practicality.  The cube's addition brought the height of the building up to 110 metres.
