Sakan (plasterwork). Sakan (左官) refers to the plasterwork of Japan. Along with woodblock prints, ukiyo-e, Japanese pottery and porcelain, Sakan is a genre of traditional Japanese craft. It flourished during the Edo period (1603-1868) and continues to be practiced in the present day.

Recently, Japanese artists have been creating modern interpretations of sakan plasterwork as a form of art.

Traditionally, earth, lime, plant fibers, sands and aggregates are the most common constituents in Japanese plaster. It was often used for traditional buildings such as tea houses and storehouses. Plaster can survive both moisture and extremely dry environments, making it an ideal material for Japan, where the humidity levels vary greatly throughout the year. It can also withstand large earthquakes, up to level 7.

Trifluoromethyl cation. The trifluoromethyl cation is a molecular cation with a formula of . It is a carbocation due to its positively charged carbon atom. It is part of the family of carbenium ions, with three fluorine atoms as substituents in place of its hydrogen atoms.

Stability 
Compared to methenium (the simplest carbenium ion), trifluoromethyl cation is more stable due to the presence of fluorine atoms. The fluorine atoms have lone pairs of electrons overlapping with the carbon atom. These electrons stabilize the positive charge of the central carbon atom, stabilizing the molecule as a whole. The overlap is effective due to the size of fluorine's p orbital in the molecule.

Synthesis 
While electron-donating fluorine lone pairs are present, it does not exist as its own. The production of a  cation has been described as "extremely hard".  The first relevant reagent, a diaryl(trifluoromethyl) sulfonium salt () was developed in 1984 by reaction of an aryltrifluoromethyl sulfoxide 1 with  followed by reaction with an electron-rich arene. Now the reaction of the source of the cation usually uses 5-(trifluoromethyl)dibenzothiophenium tetrafluoroborate as the reagent.

Bagger 1473. Bagger 1473 (christened as The Blue Wonder) is a Type SRs 1500-series bucket-wheel excavator prototype left abandoned in a field in the municipality of Schipkau in Germany.

Technical data 
The bucket wheel excavator had a power of 5555 kW during operation and was supplied with a 6 kV power cable.

Overall, the bucket wheel excavator is about 50 meters high and about 171.5 meters long. The six-section crawler undercarriage, with a maximum travel speed of 6 meters per minute, carries the total mass of 3850 tons.

With 10 buckets of 1.5 cubic meters each and 57 pours per minute (known as the pour rate), the excavator achieves a theoretical mining capacity of 5130 cubic meters per hour. The bucket wheel diameter is 12.5 meters and the cutting speed is 3.73 meters per second.

The design of the wheel boom, with a length of 67 meters, enables an excavation height of up to 35 meters and an excavation depth of up to 15 meters.

History 

The excavator was used at the Tagebau Meuro mine from 1965 to 2002.

After it was withdrawn from service, the municipalities Senftenberg, Großräschen, and Schipkau decided on a joint action to preserve the opencast mining machine. Between 29 August to 15 September 2003, Bagger 1473 was moved approximately  from the Meuro mine to near the EuroSpeedway Lausitz, where it would serve as a monument to the area's former lignite mining. The machine was moved across industrial roads and railways owned by the LMBV but public traffic was not affected.

When Bagger 1473 became popular with the urban explorers, it was misidentified as Bagger 258 because of markings found on its information plate.

Scrapping 
In January 2019 the municipalities that supported its move announced that the excavator was to be scrapped. Their decision was mainly due to the machine's dilapidation and damage. It was financially impossible to maintain and because vandalism and theft had become so extensive, the structure was no longer safe for people. Parts of the excavator would be preserved, such as its wheel.

However, when the Brandenburg Landesamt für Denkmalpflege (State Office for the Preservation of Monuments) and state archaeological museum learned of the planned demolition from news reports, they issued a statement the excavator had acknowledged historical structure protection since 2002/2003. Although at that time, it was simply assumed that it was unnecessary to formally place it on the list of such structures. The fact that the structure was identified as historically significant was considered sufficient to declare it as protected. The Landesamt quickly made it official in February.

Constructive discussions about the future of Bagger 1473 are ongoing with the local municipalities and communities. Despite imminent demolition work being prevented, it remains unclear how the structure can be preserved and who will have financial responsibility.

Eight Man (video game). is a side-scrolling beat 'em up arcade video game developed by Pallas and published internationally by SNK for both the Neo Geo MVS (arcade) and Neo Geo AES (home) platforms in 1991. It is based on Kazumasa Hirai's 1963 manga and anime superhero of the same name, who is considered one of the earliest cyborg superhero characters from Japan. Staying true to its concept of a crime-fighting super-robot, players take the role of 8 Man and his robo-comrade 9 Man respectively in a fight against an invading evil robot army.

Gameplay 

Eight Man is a side-scrolling beat 'em up game where players control the cyborg superhero 8 Man (P1) and his former rival comrade 9 Man (P2), across ten stages that take place in a futuristic setting where a bio-computer system called Cyber is threatening mankind with his army of robots. During gameplay, players can only move between left and right in the levels, while enemies are fought with either the A or C button (which activates the character's special attack), in addition of the B button that serves for jumping and pressing it when holding the joystick down, the characters perform a slide movement. The levels are broken into different phases and some of them involves the players chasing a vehicle, while enemies are coming out to attack. Power-ups are also scattered along the way to be collected that will enhance the player's attacks, as well as granting screen-clearing bombs that damages all enemies in sight. After reaching the end of a level, a boss must be fought in order to progress onto the next stage.

If a memory card is present, the player is allowed to save their progress and resume into the last stage the game saved at.

Release 
Eight Man was initially launched for arcades on June 7, 1991, and later during the same period for the Neo Geo AES in November 1991

Reception 

RePlay reported Eight Man to be the fourth most-popular arcade game at the time. Eight Man received mixed to positive reception since its initial release in arcades and Neo Geo AES.

Data sonification. Data sonification is the presentation of data as sound using sonification. It is the auditory equivalent of the more established practice of data visualization.

Process 
The usual process for data sonification is directing digital media of a dataset through a software synthesizer and into a digital-to-analog converter to produce sound for humans to experience. Benefits to interpreting data through sonification include accessibility, pattern recognition, education, and artistic expression.

Applications 
Applications of data sonification include astronomy studies of star creation, interpreting cluster analysis, and geoscience. Various projects describe the production of sonifications as a collaboration between scientists and musicians.

A target demographic for using data sonification is the blind community because of the inaccessibility of data visualizations.

One of the earliest examples of data sonification is the Geiger counter, which measures ionizing radiation through sound. Another notable example of data sonification is NASA's processing of images from space telescopes into sounds.

Ascent Abort-2. Ascent Abort-2 (AA-2) was a test of the launch escape system (LAS) of NASA's Orion spacecraft.

The test followed Orion's Pad Abort-1 test in 2010 and Exploration Flight Test-1 in 2014 in which the capsule first flew in space. It preceded an uncrewed flight of Orion around the Moon as the Artemis 1 mission, and paves the way for human use of Orion in subsequent missions of the Artemis program. 

The test flight lifted off from Space Launch Complex 46 at Cape Canaveral Air Force Station on 2 July 2019 at 11:00 UTC (07:00 EDT, local time at the launch site). The flight was successful, and the launch abort system performed as designed.

Mission highlights 
An Orion test article, aerodynamically similar to but lacking the full features of the space-tested capsule, was launched from Cape Canaveral SLC-46 by the purpose-built Orion Abort Test Booster (ATB). The booster was a repurposed Peacekeeper missile first stage (SR118) procured from the United States Air Force and modified for the mission by Orbital ATK/Northrop Grumman, similar to the first stage of the Peacekeeper-derived Minotaur IV. The mission's goal was to demonstrate and qualify the Orion Launch Abort System (LAS) that will allow the astronaut crew to safely escape in the event of an emergency during launch pad operations, through the ascent phase of the Orion vehicle.

The LAS was set to activate after around 55 seconds of ascent at an altitude of , close to the point of maximum dynamic pressure, while the booster was still firing. No parachute system was installed on the Crew Module because they are very expensive and have already been tested multiple times. The test article transmitted telemetry data during its flight, and as a backup 12 data recorders were ejected in pairs during its descent, starting about 20 seconds after separation of the capsule from the abort motor. They were recovered from the Atlantic Ocean.

Metro Riel. Metro Riel is a light rail line proposed for Guatemala's capital, Guatemala City.

Background
In October 2016, it was reported that Spanish consulting engineer IDOM conducted a feasibility study into a  light rail system for Guatemala City, evaluating the cost at $770 million. Journeys between the two termini of the line would take around 40 minutes at a commercial speed of  on a largely segregated alignment. The project was then shelved, but revisited in 2018.

In April 2019, the Guatemalan national competition agency Pronacom and public private partnership promotion agency Anadie began seeking a consultant for an advanced design study for Metro Riel.

Construction
In 2019, the municipality of Guatemala City signed an agreement with the country’s railway infrastructure manager Ferrovías to use an abandoned heavy rail alignment for the project. Construction is expected to begin in 2021.

Plumbene. Plumbene is a material made up of a single layer of lead atoms. The material is created in a process similar to that of graphene, silicene, germanene, and stanene, in which high vacuum and high temperature are used to deposit a layer of lead atoms on a substrate. High-quality thin films of plumbene have revealed two-dimensional honeycomb structures. First researched by Indian scientists, further investigations are being done around the world.

Preparation and structure
In April 2019, J. Yuhara and others reported the deposition of a single atom thickness by molecular beam epitaxy with a segregation method upon a palladium surface in a crystal lattice with Miller indices (111). The structure was confirmed with scanning tunneling microscopy (STM) revealing a nearly flat honeycomb structure. There is no evidence of any three-dimensional islands, but one notices a unique nanostructured tessellation all over the terraces looking like a space-filling polyhedral foam reduced to dimension 2.

Properties
Plumbene's electronic and optical properties have been determined from ab initio calculations, indicating a band gap of 0.4 eV.
