Open wire. Open wire was an early transmission technology in telecommunication, first used in telegraphy. It consisted of pairs of electric wire strung on a pole line between communities, towns, and cities.

The wire of the transmission line was attached to the cross-arms of each pole with glass insulators. It was originally manufactured from iron or steel, but developments in annealing of copper made it possible to use this metal by the 1890s to reduce electrical resistance substantially. Copper wire was drawn to a diameter of up to 1/6 inch (165 mils).

The glass insulators on the pole cross-arms were spaced at about 12 inches (30cm) apart. Typically up to five wire pairs were installed on each crossarm, and multiple cross-arms could be installed on each pole.

The practical limit in distance of telephone communication via open-wire transmission was reached when the Bell System long-distance network was extended from New York City to Denver in 1911. Despite heavy-gauge wire, and using loading coils to reduce transmission loss, talking was just barely possible over the line until the first Audion amplifiers were added.

Launcher (company). Launcher was an American aerospace company based in Hawthorne, California. It was founded in New York City in 2017 by Max Haot.

In February 2019 the company presented its E-2 engine, which was made in Germany by AMCM using its specialized M4K printer. The engine uses liquid oxygen and kerosene propellants. The company's Launcher Light rocket was designed to carry payloads of up to 150 kg to low Earth orbit.

In November 2019 the US Air Force awarded the company $1.5 million to accelerate development and testing of its E-2 rocket engine.

In March 2021 Launcher moved its headquarters from New York to a 24,000-square-foot building in Hawthorne, California.

In February 2023 Launcher was acquired by Vast, a startup company developing artificial gravity space stations, with Max Haot becoming Vast's president.

Orbiter 
The company has developed an orbital transfer vehicle named Orbiter that uses ethane and nitrous oxide as propellants for use as the third stage of the canceled Light rocket, or for use on other launch vehicles. In June 2021, the company raised $11.7 million in a Series-A round of funding to accelerate the development of its first orbital vehicle. Orbiter is compatible with both Launcher Light and SpaceX Falcon rideshare flights.

SN1, Orbiter's first mission was launched on January 3, 2023, from Cape Canaveral, Florida on SpaceX's Falcon 9 Transporter-6 rideshare flight, transporting payload from eight customers. SN1 failed shortly after deployment, with all but one customer payloads lost.

Following Vast's acquisition of Launcher the Orbiter program was discontinued, with the company now focusing on the development of the E-2 liquid rocket engine.

Caño Martín Peña Nature Reserve. Caño Martín Peña Nature Reserve (Spanish: Reserva Natural Caño Martín Peña) is a nature reserve in San Juan, Puerto Rico located along the 3.75 mile long Martín Peña Channel. The nature reserve protects wetlands and an urban mangrove forest which extends throughout the channel between the Los Corozos and San José Lagoons in the east and the San Juan Bay in the west, and between the districts of Santurce in the north and Hato Rey in the south. This reserve is managed by the Puerto Rico Department of Natural and Environmental Resources (DRNA) and belongs to the larger San Juan Bay National Estuary, the only tropical estuary in the National Estuary Program network.

History 
This nature reserve is bordered by a number of residential areas, such as the Martín Peña neighborhood which formed in 1940 during the Great Depression. This community is constantly threatened by floods from the channel, and from industrial pollution which also threatens the ecosystem of the mangrove forest. The community formed the Caño Martín Peña Community Land Trust in 2017 which aims to formally legalize the housing in the neighborhood, guarantee safe and sustainable housing, relocating the families that live in critical flooding areas, and to aid and develop the ecological sustainability of the area.

Ecology 

The Caño Martín Peña Nature Reserve is home to a mangrove forest which is home to a number of animal and plant species in the middle of the highly urbanized San Juan metropolitan area. All four species of mangrove that occurs in Puerto Rico can be found within the nature reserve: the red mangrove (Rhizophora mangle), black mangrove (Avicennia germinans), white mangrove (Laguncalaria racemosa) and button mangrove (Conocarpus erectus). The reserve is home to large populations of invasive species such as green iguanas, lionfish, caimans and alligators. The area is also important to a number of migratory bird species such as the merlin (Falco columbarius).

Some common native bird species include: little egrets (Egretta garzetta), little blue herons (Egretta caerulea), snowy egrets (Egretta thula), tricolored heron (Egretta tricolor), great egrets (Ardea alba), great white herons (Ardea herodias occidentalis), brown pelicans (Pelecanus occidentalis), yellow-crowned night herons (Nyctanassa violacea) and black-crowned night herons (Nycticorax nycticorax).

Recreation 
The nature reserve is open to visitors who are allowed access through the Enrique Martí Coll Linear Park (Parque Lineal Enrique Martí Coll) by entrances located in the San Juan Central Park (Parque Central de San Juan) in the western edge of the reserve, the Teófilo "Teo" Cruz Park at the midpoint in Santurce, and the AcuaExpreso ferry Hato Rey Terminal and Trocadero Diverplex next to the rapid-transit Tren Urbano station of Hato Rey by the Choliseo.

Slippery road training. Slippery road training is the driving on a closed area with a slippery surface as a part of training road users in driving on slippery roads.

It is used in some countries as a mandatory prerequisite for a driving test, or by drivers who wish to practice their maneuvering skills in slippery conditions. Such training can also detect faults in the brakes or steering of a vehicle which can have a major impact on emergency maneuvers.

Track construction 
In order to be able to simulate wet icy conditions all year around, slippery tracks have traditionally been made using iron plates on the ground upon which an oil film is sprayed. On newer courses, epoxy is often used instead, which only needs to be applied with water to achieve the same effect.

Training requirement for driving license

Norway 
In Norway, slippery road training is a mandatory part of training which must be completed for everyone taking their driving test, and goes under the name glattkjøring (or officially: sikkerhetskurs på bane). The exam task consists of regaining control of the vehicle after skidding when braking or turning, as well as adapting driving behavior on slippery roads. A standard slippery track therefore has a long straight for braking, and a curve for turning training. Some courses also have a slippery slope. Normally, a slippery road also has markers in cardboard or similar soft material which can be remotely controlled by the driving instructor to simulate obstacles in the road that the driver must avoid (e.g. a running moose or pedestrians). The Norwegian Automobile Federation owns and operates 26 slippery road tracks in Norway.

Lavinite. Lavinite () is a mixture of metal particles (usually iron) and sand held together by solidified molten sulfur. Instead of metal particles, magnesite could be used to give a whiter product. The idea was to make a material that looks like marble.

It was invented c. 1912 by Willy Henker, who in that year opened the factory "Kunststein-Industrie W. Henker & Co" in Berlin, which was in operation until at least 1936. Henker produced decorative items from lavinite such as vases, candlesticks, lamps, chandeliers and rosettes as well as letters and advertising signs.

Lavinite products were usually black, less often white or colored, enameled or covered with "antique" bronze. Initially, the factory offered items in the Art Nouveau style. Later they introduced lines in antique, oriental and Art Deco styles.

In 1922, Kunststein-Industrie W. Henker & Co opened a sales office in New York City and lavinite became very popular in the United States. Afterwards, Henker sold the patent for lavinite production to the U.S., France, Austria and Poland. In 1923 the factory "Lavinit. Krupka I Perlicz" opened in Włocławek, Poland, where it operated until 1939. They offered products from Willy Henker's factory catalogue. Over time, the assortment was expanded by items referring to the history of Poland, such as busts of Prince Józef Poniatowski or Adam Mickiewicz. For a short time, lavinite items were also produced by the Wulkanit factory in Grudziądz.

Currently, decorative items in lavinite are popular and valued at auctions all around the world. The biggest collection of them, comprising 63 items, is in the Muzeum Ziemi Kujawskiej i Dobrzyńskiej in Włocławek.
