Allendeite. Allendeite, Sc4Zr3O12, is an oxide mineral. Allendeite was discovered in a small ultrarefractory inclusion within the Allende meteorite. This inclusion has been named ACM-1.  It is one of several scandium rich minerals that have been found in meteorites. Allendeite is trigonal, with a calculated density of 4.84 g/cm3. The new mineral was found along with hexamolybdenum. These minerals, are believed to demonstrate conditions during the early stages of the Solar System, as is the case with many CV3 carbonaceous chondrites such as the Allende meteorite.  It is named after the Allende meteorite that fell in 1969 near Pueblito de Allende, Chihuahua, Mexico.

Occurrence 
Allendeite was found as nano-crystals in an ultrarefractory inclusion in the Allende meteorite. The Allende meteorite has shown to be full of new minerals, after nearly forty years it has produced one in ten of the now known minerals in meteorites. This CV3 carbonaceous chondrite was the largest ever recovered on earth and is referred to as the best-studied meteorite in history. The inclusion has only been viewed via electron microscopy. The sample is one centimeter in diameter and has been entrusted to the Smithsonian Institution's National Museum of Natural History with the catalog number USNM7554. One crystal studied is a single 15 x 25 micron size with included perovskite, various osmium-iridium-molybdenum-tungsten alloys, and scandium-stabilized tazheranite. In fact, all allendeite was in contact with perovskite. The grains are anhedral, with no observable crystal forms or twinning.

Significance
Various scandium rich minerals have been found in meteorites, including; davisite, panguite, kangite, tazheranite, thortveitite, and eringaite. Of these, allendeite is the most Sc rich, with only pretulite containing substantially more scandium.

Appearance
Color, streak, luster, hardness, tenacity, cleavage, fracture, density, and refractive index could not be observed because the grain size was too small and the section bearing the mineral was optically thick.

Charlesite. Charlesite is a sulfate mineral of the ettringite group. Charlesite was named in 1945 after Dr. Charles Palache  mineralogist and professor at Harvard University for his work on minerals. This mineral is extremely rare, and when it is found it is often in crystal (but not gem) form. Its crystals are soft hexagonal, that can vary in color. Colors can range from clear to white, or even a pale yellow or pink. The brittle mineral's Mohs hardness is 2.5 with a specific gravity of 1.79. Though transparent to the eye the mineral has a white streak.

Occurrence 

Charlesite has only been found in a few specific locations in the world. The first was its place of discovery in Franklin Mine in Franklin, Sussex County, New Jersey. It was located immediately above the 800 level, about 15 feet into the ore from the hanging wall. The ore mostly consisted of franklinite and willemite and several other minor minerals. The crystals found at this location were up to 6mm in length and were suspected to have grown alongside clinohedrite crystals.

The other location where charlesite has been located is the Wessel's Mine, N' Chwaning Mines, and Kalahari Manganese Fields in Northern Cape Province, South Africa. The Wessel's Mine is thought to be the only source for charlesite to be found in gem quality.

Several of the other recorded places are Germany, Japan, Norway, Romania, and Slovakia.

Uses

Due to its rarity, there are not very many uses for charlesite. Though there is not much of the mineral, one of the major uses for the ones that reach the standards is gems. Due to its softness it will not be found in much jewelry.

Some other uses could be for studying (the reasons for the rarity of the mineral), teaching mineralogy classes, or even items for collectors or museums of rare minerals.

Garrod and Lofthouse. Garrod and Lofthouse were a British printing company based in Chaldon Road, Caterham, Surrey, who manufactured record sleeves. In 1963, the company patented the design for Two-Piece sleeves that were used in the UK.

The advantage of these sleeves, in the days of single colour printing, was that the four-colour front was printed on a separate sheet to the single colour back and the two halves were then glued together as the sleeve was fabricated. This allowed half the number of passes through a printing press to produce the front cover, and a quarter for the monochrome backs. This gave a reduction in print costs of 37.5%. As the two fronts could be laminated together, it halved the amount of laminating time.

Because of these cost reductions the company were contracted to print sleeves for 90% of all EMI affiliated labels volume on the basis that they never produced a sleeve for Decca Records, their only major competitor. They are therefore credited on all original LP releases of the Beatles, including Sgt. Pepper's Lonely Hearts Club Band.

Garrod and Lofthouse printed for most UK record companies outside Decca, and manufactured covers for France through a subsidiary Imprimerie du Nord. They were given special permission to press the Rolling Stones' Beggars Banquet (one of the first gatefold sleeves) and Sticky Fingers (manufactured with a metal zip glued down the front), as Decca's in-house staff could not manage the complex production to the volume required.

The company was liquidated in 1988, by which time sleeve manufacturing could be done by any generic process, and cassette and compact disc sleeves did not require carboard printing.

Experience Curiosity. Experience Curiosity is an interactive web application developed by NASA's Jet Propulsion Laboratory to celebrate the third anniversary of the Curiosity rover landing on Mars. This 3D serious game
makes it possible to operate the rover, control its cameras and the robotic arm and reproduces some of the prominent events of the Mars Science Laboratory mission. The application was presented at the beginning of the WebGL section at SIGGRAPH 2015.

According to Brian Kumanchik, the lead and art director behind the project, the development team used exclusively open-source software including Blender and GIMP for creating 3D content, particularly due to public accessibility of open source formats. The Blend4Web framework was chosen as a 3D engine which is integrated with Blender, includes a physics engine and provides rendering in mobile browsers. In 2018, the application was ported to Verge3D framework.

Experience Curiosity won the Webby Award as the best "Government & Civil Innovation" website of 2016. The 5-word speech at the award ceremony was Rockin' and Rovin' on Mars, voiced by NASA's representative Brian Kumanchik.

SFCA Lignel 46 Coach. The SFCA Lignel 46 Coach was a French four seat touring aircraft built soon after World War II. It was SFCA's last design, with two prototypes built, flown and raced but engine supply problems prevented production.

Design and development

The Lignel 46 was the last aircraft produced by Société Française de Construction Aéronautique (SFCA). It was a cantilever low wing monoplane, seating four in two side-by-side rows under a multipart glazed canopy.  The two main transparencies opened away from each other on vertical, forward hinges for cabin access. There was a  Mathis G8R or Mathis G8 20 inverted V-8 engine, driving an automatic variable pitch propeller in the nose; behind the cabin the fuselage tapered linearly from the full cabin depth.  The Lignel 46 was a wooden aircraft and its monocoque fuselage was built using a composite shell composed of perforated cork sheets between inner and outer shaped plywood layers, a method patented by Jean Broudeau and one that SFCA had explored before World War II.

The wings of the Lignel 46 were broadly similar to those of the SFCA Lignel 20.  The central and outer panels were distinguished by the lack of dihedral on the former; both had straight, unswept leading edges but the trailing edge of the outer panels was curved, producing a roughly elliptical plan.  Like the Lignel 20 the 46 had somewhat inset ailerons and split flaps.  The Lignel 46 also had unusual, very small fixed leading edge slots at the wing tips. Apart from its variable incidence tailplane, mounted at mid-height on the fuselage, the empennage was conventional, with a rounded fin and rudder. It had a fixed, tailwheel undercarriage with both landing legs and wheels in aircraft fairings.

The SFCA Lignel 46 first flew on 13 August 1947. Two were completed. One of them was on display at the 18th Paris Aeronautical Salon which opened on 29 May 1949, by which time it had done significant flying. Mathis went out of business in 1950 and SFCA decided not to re-engine the Type 46, though the two prototypes remained active until at least 1951.

Operational history

In its short operational life the Lignal 46 took part in several major competitions.  Its best result by far was in 1948, when Jean Lignel took it to first place from a field of over fifty aircraft contesting the Italian Rally.   In the summer of 1949 one flew in the Grand Prix de Meaux, though without distinction. The following year the second prototype F-BCFS  participated in the South Coast race in England, flown by its designer, finishing well down the field despite recording a speed of . In 1951 Louis Clément flew the first prototype F-BCZJ in the same race, finishing in mid-field.

Christopher Peter Jürgensen. Christopher Peter Jürgensen (30 October 1838 – 26 December 1911) was a Danish precision mechanician and instrument maker.

Early life and education
Jürgensen was born in Gesing near Randers. He was sent to Copenhagen at age 13 where he apprenticed at the instrument maker Julius Nissen's workshop in Købmagergade. He also attended the Technical Institute and in 1860 a scholarship enabled him to visit several leading workshops abroad.

Career

Back in Denmark, he began to work for Edvard Jünger whose company he took over in 1869. The company was located at Sortedam Dossering (No. 37). Under his management the company developed into the leading manufacturer of optical, geodetical and nautical instruments in the Nordic countries. He collaborated with Rasmus Malling-Hansen on the development of the Writing Ball which he also manufactured. Jürgensen's instruments were noted for their precision. His customers included the Danish, Norwegian and Swedish armies and navies, Østervold Observatory in Copenhagen and scientists both in Denmark and abroad. With the growing significance of electricity in lighting in the 1880s, Jürgensen changed the profile of his company which was responsible for many large installations.

The company won a gold medal at the International Exposition of Electricity in Paris in 1881. Two new partners joined the company and it was converted into an aktieselskab in 1887. A new section for electric engines was established. It also moved to larger premises in Møllegade (No. 28). In 1890, in collaboration with Siemens & Halske, the company signed a contract for the construction of Copenhagen's first central power station in Adelgade. In the 1900s, the company came into economic difficulties and went bankrupt in 1906.

Polyglot persistence. Polyglot persistence is using multiple data storage technologies within a single system, in order to meet varying data storage needs. Such a system may consist of multiple applications, or it may be a single application with smaller components.

Description 
Polyglot persistence shares its origins with how the term polyglot programming is defined. Polyglot programming is a term coined by Neal Ford in 2006, and expresses the idea that computer applications should be written in a mix of different programming languages, in order to take advantage of the fact that different languages are suitable for tackling different problems. Complex applications combine different types of problems, so picking the right language for each job may be more productive than trying to solve all aspects of the problem using a single language. This same concept can be applied to databases, that an application can communicate with different databases, using each for what it is best at to achieve an end goal, hence the term polyglot persistence.

Since there are numerous databases available to solve different problems, using a single database to satisfy all of a program's requirements can result in a non-performant, "jack of all trades, master of none" solution. Relational databases, for example, are good at enforcing relationships that exist between various data tables. To discover a relationship or to find data from different tables that belong to the same object, an SQL join operation can be used. This might work when the data is smaller in size, but becomes problematic when the data involved grows larger. A graph database might solve the problem of relationships in case of Big Data, but it might not solve the problem of database transactions, which may be provided better by  relational database management systems. Instead, a NoSQL document database might be used to store unstructured data for that particular part of the problem. Thus different problems are solved by different database systems, all within the same application.

Some of such data storage technologies, but not limited to, could be

 Relational
 NoSQL 
 Graph
 In-memory

Martin Fowler writes in one of his articles, "One of the interesting consequences of this is that we are gearing up for a shift to polyglot persistence where any decent sized enterprise will have a variety of different data storage technologies for different kinds of data. There will still be large amounts of it managed in relational stores, but increasingly we'll be first asking how we want to manipulate the data and only then figuring out what technology is the best bet for it."
