Prismet. Prismet (English: The Prism) is an office building in Aarhus, Denmark. It is one of the tallest buildings in the city and it was the first building more than 50 meters tall built in Aarhus city center since the early 1970s. Prismet was built by the Danish investment group PFA Byg A/S between 1999 and 2002. The contractor was H. Hoffmann & Sønner A/S, the engineer Birch & Krogboe A/S and the architect company Friis & Moltke. The landscape architect firm Schønherr designed the outdoors areas, including a small park. The project covers 17800 m2.

Controversy 
Prismet is known for its location in proximity to the Old Town Museum from which the building is clearly visible and offers a strong contrast to the old, half-timbered buildings in the museum. Prismet has been criticized for ruining the illusion of being in a medieval town.

Structurally nanoengineered antimicrobial polypeptide polymers. Structurally nanoengineered antimicrobial polypeptide polymers (SNAPPs) are a type of artificially designed synthetic antimicrobial peptide. The development of the polymers is potentially a  treatment for bacterial diseases. The research takes a novel approach to combating bacteria; rather than poisoning them as antibiotics do, SNAPPs and other antimicrobial peptides tear the bacteria apart.

Structure and characteristics 
The molecule destabilizes the structure of the outer membrane and cytoplasmic membrane in multi-drug resistant gram-negative bacteria with no resistance observed by the researchers through multiple bacterial generations. While no human trials have been approved yet, the molecule has been tested in vivo with the mouse peritonitis model, and was shown to be highly selective towards bacterial cell walls, leaving mammalian cells unharmed.  Bacteria species tested include E. coli and K. pneumoniae, along with variants of P. aeruginosa and A. baumannii. SNAPPs work by literally tearing the cell wall and cytoplasmic membrane apart, leading to cell death. Their structure physically resembles a star. At the core of their structure is a multi-functional initiator poly(amidoamine) with 16 or 32 primary amines. Lysine and valine amino acids are polymerized to the N-terminus of the core in order to form either an S16 (16 arm SNAPP) or S32 (32 arm SNAPP). The polymerized peptide chains result in several positively charged primary ammonium cations, which help adhere the negatively charged end of the phospholipid bi-layer.

Rocker Shovel Loader. A Rocker Shovel Loader, sometimes simply referred to as a Rocker Shovel or Mucker is a type of mechanical loader used in underground mining.

A Rocker Shovel is usually powered by compressed air, or in some cases electricity. It is commonly mounted on steel wheels designed to run on narrow gauge rails, with some later models using metal or rubber-tyred road wheels. The operator, standing on a raised platform to one side of the machine, operates the controls, one lever to drive the machine along the tracks, and another to raise and lower the bucket. Once the bucket has been filled by driving the loader forwards into the pile of material, the rocker mechanism throws the contents over the top of the machine and into a wagon behind. Once full, the loaded wagon can be taken away and replaced with an empty one to allow loading to continue.

On 28 May 1937, Edwin Burton Royle applied for a patent as inventor of the "loading machine" and US Patent No. 2,134,582 was issued on October 25, 1938 and assigned to the Eastern Iron Metals Company (later to be known as EIMCO).

In 2000, the American Society of Mechanical Engineers added the EIMCO 12B Rocker Shovel Loader of 1938 to its List of Historic Mechanical Engineering Landmarks as reference number 212 out of a total number of 259 objects (as of 2015).

In June 2012, an EIMCO 12B Rocker Shovel was featured in an episode of the American reality television series Auction Hunters, filmed in Littleton, Colorado. It was sold to a gold miner for $3,600.

Berzelianite. Berzelianite is a rare copper selenide mineral with the formula Cu2Se. It occurs as thin dendritic crusts or as fine-grained inclusions. It crystallizes in the isometric system, unlike its dimorph, bellidoite, which crystallizes in the tetragonal system. The crystals are opaque and slightly malleable.

Occurrence and name 
Berzelianite was first identified at the Skrikerum Mine (also spelled as Skrickerum Mine) in Valdemarsvik, Östergötland, Sweden in 1850. 

It was named by James Dwight Dana to honor Jöns Jakob Berzelius, a Swedish chemist who is seen as the father of analytical chemistry. He invented chemical symbol notation and discovered the elements cerium, selenium, silicon, and thorium. 

Berzelianite often occurs together with eucairite, clausthalite, tiemannite, umangite, klockmannite, aguilarite, crookesite, athabascaite, stromeyerite, polybasite, pearceite, gold, uraninite, pyrite, marcasite, calcite.

Polarograph. A Polarograph is a chemical analysis instrument used to record automatic voltage-intensity curves.

The Polarograph uses an electrolytic cell consisting of an electrode or microelectrode small area, generally of the mercury drop type, which is a very fine capillary tube through which mercury flows slowly, which comes in the form of small droplets, which fall on the same surface of a much broader element, which is the other electrode .  When one applies a variable voltage in this cell, the electrode's large area remains unchanged, while the microelectrode undergoes a change of potential, ( i.e. is polarized).  It also has a potentiometer coupled to the motor that moves the recording paper so that a certain voltage variation corresponds to a constant length of recording paper, and a galvanometer suitable for measuring the intensity of the electric current, whose response is transmitted to the actuator that moves the needle of the recorder.  The technique used is called polarography. The Czech chemist and Nobel Prize winner Jaroslav Heyrovský invented it.

Eskebornite. Eskebornite is a selenide mineral with the formula CuFeSe2. It crystallizes in the tetragonal system and it has a brassy colour. Eskebornite is sometimes found as thick tabular crystals, but is more often found intergrown with other selenides. It is part of the chalcopyrite group and forms a series with chalcopyrite.

Occurrence 
Eskebornite was first identified in 1949 by Paul Ramdohr in the Eskaborn Adit, Tilkerode (Abberode), Harz, Saxony-Anhalt, Germany, which it was also named after. It is often found with other selenides, including clausthalite, tiemannite, berzelianite, naumannite, umangite, geffroyite, and chaméanite, but also with other minerals like chalcopyrite, uraninite, ankerite, and dolomite.

A-Frame (virtual reality framework). A-Frame is an open-source web framework, written in JavaScript, for building virtual reality (VR) experiences. It is maintained by developers from Supermedium (Diego Marcos, Kevin Ngo) and Google (Don McCurdy). A-Frame is an entity component system framework for Three.js where developers can create 3D and WebXR scenes using HTML. HTML provides a familiar authoring tool for web developers and designers while incorporating a popular game development pattern used by engines such as Unity.

History 
A-Frame was originally developed within the Mozilla VR team during mid-to-late 2015. A-Frame was created in order to allow web developers and designers to author 3D and VR experiences with HTML without having to know WebGL. A-Frame's first public release was on December 16, 2015. On December 16, 2019 A-Frame version 1.0.0 was released.

Community 
All online IDEs support A-Frame as a result of being based on HTML. Documentation is available for the API. Support for developers committing to the library is provided via GitHub issues, while support for developers building apps and web pages is provided via StackOverflow. Real-time on-line support is provided via Slack. Most of the developers are also on Twitter.

Usage

Musée aéronautique et spatial Safran. The Musée aéronautique et spatial Safran () is a French private aviation museum located in Melun, Seine-et-Marne. Established in May 1989 the museum contains a large collection of historic and modern aircraft engines. These engines have been produced by various French engine manufacturers such as Gnome et Rhône and Snecma which are now part of the present day Safran company. The latter is the creator and manager of the museum.

The main exhibits are piston engines and turbojets that powered aircraft as well as rocket engines used for aircraft and spacecraft. All the exhibits were developed and produced by companies that were eventually merged into the Safran group.

History

In 1985 the Musée de l'Air et de l'Espace, Le Bourget held more than 1,000 historic aero engines. Snecma signed an agreement to allow their restoration and future care. The agreement stated that employees of Snecma would restore the engines as volunteers. In 1987 Snecma decided to create a new museum to display the restored engines, the museum was created on the site of its Villaroche establishment in Melun in a former seaplane hangar of 4,000 m2. Inaugurated on 31 May 1989 the 'Association of Friends of the Museum Safran' manages the museum. In 2013 the museum was expanded to accommodate a section on space propulsion.

Collections

The museum's collections are presented with a parallel theme depicting the history of aviation and aerospace. Exhibits include aircraft, piston engines, gas turbine engines, rocket engines, and aerospace items.

Campani compound microscope. The Campani compound microscope is a microscope on exhibit at the Museo Galileo in Italy, thought to have been built by optical instrument maker Giuseppe Campani in the second half 17th century. For a time it was thought to have been built by Italian scientist Galileo Galilei but no longer bares that attribution.

Description
This Museo Galileo microscope is a compound microscope made of cardboard, leather and wood, and is inserted in an iron support with three curved legs. The outer tube is covered in green vellum decorated with gold tooling. There are three lenses (an objective lens, a field lens, and an eyepiece), all double-convex. The objective measures 11 mm in diameter and has a thickness of 3.5 mm. The glass is clear with few imperfections; the edge is ground and there are some fine chips. The field lens (diameter 30 mm, thickness 4.7 mm) is in a cell that pushes into the bottom of the inner tube. The glass is amber-green, with air bubbles, and has a ground edge that is chipped; the eyepiece, with an aperture of 24 mm, also has some bubbles; it is protected by a wooden cap that screws onto the mount. The instrument is attributed to Giuseppe Campani, an Italian optician and astronomer who lived in Rome during the latter half of the 17th century, known as an expert lens grinder and instrument maker. Compound microscopes such as this first appeared in Europe around 1620 including one demonstrated by Cornelis Drebbel in London (around 1621) and one exhibited in Rome in 1624.

The instrument was said to have been built by Galileo but no longer bares that attribution. Galileo was known for using his 1609 telescope, which used a concave eyepiece and a convex objective, either forwards of backwards to view small objects, such as flies, close up but it was not a very practical microscope. After seeing the compound microscope built by Cornelis Drebbel exhibited in Rome in 1624 that used two convex lenses, Galileo built his own improved version. Giovanni Faber, fellow of the Accademia dei Lincei, gave the name "microscope" (microscopio) to Galileo's "small eyeglass" (occhialino) in 1625.

Thunder house. The thunder house is a scientific model invented by James Lind which gives a spectacular demonstration of the destructive effect of a lightning bolt striking a house with an imperfect lightning conductor.

The small wooden house has hinged walls and carries a brass rod representing a lightning rod. A section of the conductor runs along a piece of wood placed on the façade. Inside the house is a spark gap housed in a small brass cylinder containing a small quantity of gunpowder.

When the piece of wood is removed, the lightning-conductor circuit is broken. The lightning bolt, simulated by a spark generated by a Leyden jar, ignites the powder, whose explosion causes the house to collapse. If, instead, the piece of wood is positioned correctly, the electricity will be discharged to the ground, leaving the house intact.
Filippo Lucci depicted a similar device in the Stanzino of the Matematiche of the Uffizi Gallery in 1780—clear evidence of the popularity of such demonstrations in the late eighteenth century.
The same phenomenon is also visible through the use of a similar instrument called Thunder Obelisk.
