# Rhombic enneacontahedron

In geometry, a rhombic enneacontahedron (plural: rhombic enneacontahedra) is a polyhedron composed of 90 rhombic faces; with three, five, or six rhombi meeting at each vertex. It has 60 broad rhombi and 30 slim. The rhombic enneacontahedron is a zonohedron with a superficial resemblance to the rhombic triacontahedron.

## Construction

It can also be seen as a nonuniform truncated icosahedron with pyramids augmented to the pentagonal and hexagonal faces with heights adjusted until the dihedral angles are zero, and the two pyramid type side edges are equal length. This construction is expressed in the Conway polyhedron notation jtI with join operator j. Without the equal edge constraint, the wide rhombi are kites if limited only by the icosahedral symmetry.
The sixty broad rhombic faces in the rhombic enneacontahedron are identical to those in the rhombic dodecahedron, with diagonals in a ratio of 1 to the square root of 2. The face angles of these rhombi are approximately 70.528° and 109.471°. The thirty slim rhombic faces have face vertex angles of 41.810° and 138.189°; the diagonals are in ratio of 1 to φ$^2$.
It is also called a rhombic enenicontahedron in Lloyd Kahn's Domebook 2.

## Close-packing density

The optimal packing fraction of rhombic enneacontahedra is given by
    $\eta =16-{\frac {34}{\sqrt {5}}}\approx 0.7947377530014315$.
It was noticed that this optimal value is obtained in a Bravais lattice by de Graaf (2011). Since the rhombic enneacontahedron is contained in a rhombic dodecahedron whose inscribed sphere is identical to its own inscribed sphere, the value of the optimal packing fraction is a corollary of the Kepler conjecture: it can be achieved by putting a rhombicuboctahedron in each cell of the rhombic dodecahedral honeycomb, and it cannot be surpassed, since otherwise the optimal packing density of spheres could be surpassed by putting a sphere in each rhombicuboctahedron of the hypothetical packing which surpasses it.

# Rhombic drive

The rhombic drive is a specific method of transferring mechanical energy, or work, used when a single cylinder is used for two separately oscillating pistons.

## History

It was originally developed around 1900 for the twin-cylinder Lanchester car engine where it allowed perfect balancing of the inertial forces on both pistons. A current example of its use is on beta type-Stirling engines; the drive's complexity and tight tolerances, causing a high cost of manufacture, is a hurdle for the widespread usage of this drive.

## Operation

In its simplest form, the drive utilizes a jointed rhomboid to convert linear work from a reciprocating piston to rotational work. The connecting rod of the piston is rigid as opposed to a common reciprocating engine which directly connects the piston to the crankshaft with a flexible joint in the piston. Instead, the rod connects to one corner of a rhombus. When force is applied to the piston, it pushes down; at the same time, the outer corners of the rhomboid push out. They push on two cranks/flywheels which cause them to rotate, each in opposite directions. As the wheels rotate the rhombus progresses its change of shape from being flattened in the direction of the piston axis at top dead centre to being flattened in the perpendicular direction to the piston axis at bottom dead centre.
In the pictured example the left crank/flywheel turns clockwise and the right crank/flywheel anticlockwise. They turn at the same angular velocity and this can be reinforced by intermeshing them as gear wheels.

# Glass-Jet

Glass Jet is the name brand of a line of fiberglass runabout boats manufactured in the 1950s. These boats are some of the earliest examples of fiberglass boat construction. Inspired by aviation and the arrival of jet airplane technology, the boats have extra large tail fins like many of the automobiles of the same era. Glass Jet boats were manufactured by the J&R Plasticraft Corporation in Reeseville, Wisconsin. This firm later ceased boat manufacturing and relocated to Waterloo, Wisconsin. Boat manufacturing continued in Reeseville, Wisconsin however by Quality Plastics, Inc. which produced the "Quality Glass" line of fiberglass boats. This firm went out of business in 1961. Though production numbers are unknown, many Glass Jet boats are known to exist and are presently sought after as collector's items.
# Mode-k flattening

In multilinear algebra, mode-m flattening, also known as matrixizing, matricizing, or unfolding, is an operation that reshapes a multi-way array ${\mathcal {A}}$ into a matrix denoted by $A_{[m]}$ (a two-way array).
Matrixizing may be regarded as a generalization of the mathematical concept of vectorizing.

## Definition

The mode-m matrixizing of tensor ${\mathcal {A}}\in {\mathbb {C} }^{I_{0}\times I_{1}\times \cdots \times I_{M}},$ is defined as the matrix ${\bf {A}}_{[m]}\in {\mathbb {C} }^{I_{m}\times (I_{0}\dots I_{m-1}I_{m+1}\dots I_{M})}$. As the parenthetical ordering indicates, the mode-m column vectors are arranged by sweeping all the other mode indices through their ranges, with smaller mode indexes varying more rapidly than larger ones; thus
$[{\bf {A}}_{[m]}]_{jk}=a_{i_{1}\dots i_{m}\dots i_{M}},$ where $j=i_{m}$ and $k=1+\sum _{n=0 \atop n\neq m}^{M}(i_{n}-1)\prod _{\ell =0 \atop \ell \neq m}^{n-1}I_{\ell }.$ By comparison, the matrix ${\bf {A}}_{[m]}\in {\mathbb {C} }^{I_{m}\times (I_{m+1}\dots I_{M}I_{0}I_{1}\dots I_{m-1})}$ that results from an unfolding has columns that are the result of sweeping through all the modes in a circular manner beginning with mode m + 1 as seen in the parenthetical ordering. This is an inefficient way to matrixize.

## Applications

This operation is used in tensor algebra and its methods, such as Parafac and HOSVD.

# Salitre Mágico

Salitre Mágico is an amusement park located in Bogotá, Colombia, inside the territory of the Parque el Salitre. Currently it features 39 mechanical attractions including roller coasters, bumping cars, and the unique "Castillo del Terror" (Castle of Horror). It is one of the most important and classic amusement parks in the city, as well as the largest, among others such as the Mundo Aventura and Cici Aquapark.

## History

When the park was inaugurated in 1973 under the name "Parque El Salitre", located between 68th Avenue and 63rd Street near the Parque Simon Bolivar in Bogotá, it was considered one of the most modern amusement parks in Latin America.
Mexican firm Corporacion Interamericana de Entretenimiento (CIE) later bought the park and closed it to the public in 1999 for remodeling. Its reinauguration took place in December 2000, under the new name "Salitre Mágico", with a total of 29 rides located all over the park. Among these were a roller coaster, nicknamed "the Screw" due to its helicoidal form, which was imported from the United States and reassembled in Bogotá; some other new attractions included a giant Chicago Wheel called the "Rueda Millenium" (Millennium Wheel) which offers a panoramic view of the city from a total height of 40 metres. The Salitre Mágico also offers aquatic attractions and a wide variety of mechanical attractions and shows for children and the whole family. A brother park, Cici Aquapark, was later opened nearby, offering aquatic attractions including a sea waves simulator and several sledges. Both parks are currently part of the Mexican emporium CIE.

## Rides

Among the wide variety of rides, the park offers entertainment for children with attractions such as the Carousel, Flying Swings, the Top Spin (Apocalipsis) and mini-Wheel; some other of high impact such as the three roller coasters, the Tornado, the Double Loop and the Screw which counts with free falls up from 15 m height and a total round of 500 m.
# Mohammad Nazir Isa

Rear Admiral Mohammad Nazir Isa (10 July 1910 – 30 August 1982) was an Indonesian military officer, minister, and diplomat. He served as Chief of Staff of the Indonesian Navy from 1946 to 1948, Minister of Shipping from 1957 to 1959, and Indonesian Ambassador to Switzerland and the Vatican.

## Profile
### Early life and education

Nazir was born in Maninjau, Agam, West Sumatra, to Mohammad Isa Sutan Bandaro and Siti Chadijah, the third of seven children. From the age of six, Nazir was raised by his uncle, Adam Datuak Basa Nan Balimo, who served as a School Opzienner in Tanjung Pura, Langkat. In accordance with his uncle's position, Nazir was allowed to enter the Europeesche Lagere School in Medan. After that he was brought by another uncle, Abdul Samad who worked as a Hoof Opzichter in Batavia, and entered the primary school De Tweede Bijbel School, then he continued his education at Chrijstelike Meer Uitgebreid Lager Onderwijs (MULO).

### Naval career

Nazir worked as a sailor in the Netherlands on the recommendation of Mrs. Poijt van Druten, his teacher at MULO. After working in the shipping industry, Nazir had saved up enough money to continue his education at the Michel Adrianzoon de Ruyter Dutch shipping school, and received a De Grotevaart diploma (Ocean Cruise Certificate) in 1938, He was the first Indonesian to receive the degree. In 1938 he returned to Indonesia and worked for the shipping company, Doggerbank. After the Japanese occupation of the Dutch East Indies, he joined the Imperial Japanese Navy. In 1943, he was appointed head of the Higher Shipping School in Semarang.
After Indonesia's deceleration of independence, he and other navy captains convened to form the People's Security Agency Navy, where he became Deputy Commander, with the reorganization of the Indonesian navy he, became Chief of Staff of the Indonesian Navy with the position of Chief of General Staff of TRI Laut on 6 February 1946 and the position changed its name to Commander of the Indonesian Navy from 19 July 1946 to 8 May. On 2 January 1948 he was reassigned to Sumatra and established a navy training school.
During 1948 he became a senior adviser to Sjafruddin Prawiranegara's Emergency Government of the Republic of Indonesia and Minister of Shipping in the Djuanda Cabinet. He later signed the Petition of Fifty which criticized Suharto's totalitarian government.

### Death

# San Juan, Colón

San Juan is a corregimiento in Colón District, Colón Province, Panama with a population of 17,430 as of 2010. Its population as of 1990 was 8,716; its population as of 2000 was 13,325.
# Giuseppina Huguet

Giuseppina Huguet (22 September 1871–1951) was a Catalan operatic soprano with a lyrical voice who sang throughout Europe prior to World War I.
Huguet was born in 1871 in Barcelona and registered on official documents as "Josefina" Huguet. Her first music teacher was Francisco Bonet in Barcelona, where she soon made her operatic debut as Lakmé at the Teatro Liceu of Barcelona. She subsequently toured several countries, including some South American nations. She performed, too, with success in Italy, appearing for the first time at Milan's La Scala in 1896, where she sang the role of Ophélie in Ambroise Thomas's Hamlet. Huguet proved popular in Russia as well.
Although Huguet often sang coloratura parts, such as Rosina in Rossini's Il Barbiere di Siviglia, she also undertook the verismo roles of Mimì in Puccini's La Bohème and Cio-Cio-San in Puccini's Madama Butterfly, and her recordings even include excerpts from Wagner's Lohengrin (on which she is accompanied by the famous tenor Fernando De Lucia). Indeed, her complete repertoire contained a wide range of roles: from The Queen of Night in Mozart's The Magic Flute to Nedda in Leoncavallo's Pagliacci.
Huguet's career as a recording artist was not particularly extensive. Her discography consists mainly of arias and ensemble pieces from opera that were recorded by the Gramophone Company, forerunner of EMI. She also sang the role of Nedda in the first complete recording of Pagliacci in 1907 (with the Orchestra and Chorus of the Teatro alla Scala di Milano, Carlo Sabajno conducting). Volume One of The Record of Singing by Michael Scott (Duckworth, London, 1977) contains a synopsis of her career and an appraisal of her records, some of which are available on CD transfers.
Along with Rafael Bezares, Huguet was among a small number of Spanish opera singers to be recorded, as the Compagnie Francaise du Gramophone were more focused on native genres, such as zarzuela and flamenco. 17 commercial wax cylinder of her voice survive; she also recorded 23 cylinders privately for the industrialist Ruperto Regordosa. Huguet's coloratura soprano and high register were advantageous to her recording, as these voice types recorded particularly well on wax cylinders.

# Soyuz 7K-T-AF

Soyuz 7K-T-AF is a version of the Soyuz spacecraft and was the first spacecraft designed for space station flights, a dedicated science mission. Its only crewed flight was conducted in 1973 with Soyuz 13 of the Soyuz programme.

## Design and flight

The one craft of the Soyuz 7K-T-AF was modified from the original Soyuz 7K-T with the addition of observatory and solar arrays. This was the second test flight of the redesigned Soyuz 7K-T, the second generation of the Soyuz spacecraft. The Soyuz 7K-T-AF flew once on Soyuz 13. The Soyuz 7K-T-AF was in the 7K-TM Configuration. Soyuz 7K-T-AF propulsion was from a KTDU-35, two liquid rocket engines. Soyuz 13/7K-T-AF was the first manned space observatory. Soyuz 7K-T-AF/Soyuz 13 housed the Orion 2 Space Observatory, operated by crew member Valentin Lebedev. Orion 2 Space Observatory was an Ultraviolet (UV) Telescope. The first Soviet UV Telescope was Orion 1 used on orbital station Salyut 1. The other crew member was Pyotr Klimuk.
With the Orion 2 astrophysical telescope and camera, the crew made observations of stars in the ultraviolet light range. Also added to Soyuz 7K-T-AF was experiment that photographed spectrozonal areas of the earth's surface. Soyuz 7K-T-AF landed in snowstorm 200 kilometres (120 mi) Southwest Karaganda. The observatory equipment was added to the top of nose cone of the spacecraft. The observatory equipment was mounted were the docking port is mounted on the Soyuz 7K-OKS version. Soyuz 22/Soyuz 7K-MF6 spacecraft would be the next 7K-T with observatory equipment mounted at the craft's docking port.

# Derek Goodwin

Richard Patrick Goodwin (26 February 1920 – 14 May 2008), known as Derek Goodwin, was a British ornithologist who wrote a series of what The Times called "definitive works" on estrildid finches, crows and pigeons. He was considered to be an expert on bird behaviour.
Goodwin was born Richard Patrick Goodwin in Woking, United Kingdom, on 26 February 1920. His parents called him Derek for reasons he never fully understood, but the name stayed with him for his entire life. He served in the British military in the Royal Artillery during World War II and was a veteran of the Siege of Tobruk. He left the military in August 1945 and embarked on his career in ornithology.
Goodwin was a writer and contributor to Avicultural Magazine. By chance, in July 1945, while Goodwin was still in active duty in the military, his purchase of back issues of Avicultural Magazine led to a series of unexpected events which led to his employment at the Natural History Museum. Though he had no formal education in ornithology at the time, Goodwin was hired to work in the Natural History Museum's bird room. He eventually rose up through the ranks to become principal scientific officer for birds at the museum. In 1965 he participated in the third of the Harold Hall Australian ornithological collecting expeditions. He wrote a series of detailed books on crows, pigeons and estrildid finches during the 1970s and 1980s as part of his work at the British Museum. These works are still regarded as the definitive works on these particular birds today. He also authored and published his favorite work, Birds in Man’s World, and wrote a series of children's books and pamphlets on birds.
He was known as a prolific bird correspondents and was elected as a corresponding member of Deutsche Ornithologen-Gesellschaft in the 1970s, though he never studied German in school. He also taught and mentored noted ornithologists, such as Aubrey Manning, Rob Hume and Desmond Morris when they were students.
Goodwin was also a longtime advocate for the plight of two rare pheasant species; the golden pheasant and the Lady Amherst's pheasant. He wrote numerous letters and articles on the subject of these two birds. He even resigned from the Royal Society for the Protection of Birds to protest its perceived lack of support for saving these pheasants, which had been introduced to parts of rural England. Unlike most ornithologists and bird watchers, Goodwin supported the plight of introduced bird species in Britain and elsewhere. However, he did not support the reintroduction of raptor species, even regarding the white-tailed eagle as a potential danger to other species.
Derek Goodwin died on 14 May 2008, at the age of 88.
