Tribromoethanol. 2,2,2-Tribromoethanol, often called just tribromoethanol, is a chemical compound with formula .  Its molecule can be described as that of ethanol, with the three hydrogen atoms in position 2 (on the methyl group) replaced by bromine.  It is a white crystalline solid, soluble in water and other solvents, that absorbs strongly in the UV below 290 nm.

Tribromoethanol is used in medicine and biology as an anesthetic, and has been available commercially for that purpose by the trade name Avertin.  It was formerly used on humans and is still often used on laboratory animals, and to capture wild birds.
It is also used in plastics industry as a polymerization initiator.

Uses

Animal anesthetic
Tribromoethanol is often used to anesthetize laboratory animals, particularly rodents, before surgery. As a solution in tert-amyl alcohol, it has the brand name Avertin. The tert-amyl alcohol acts as a weak hypnotic, in addition to improving the solubility of the tribromoethanol.  Administered intravenously, tribromoethanol (Avertin) causes rapid and deep anesthesia followed by rapid and full postoperative recovery in small mammals. Recently its safety for this purpose has been questioned.

Wildlife capture
Tribromoethanol has also been long used as spiked grain bait to capture wild turkeys for research and wildlife management purposes. However, the birds learn to avoid it, for over a year, after a single exposure, and will drive other flock members away from the bait when they detect it.

Human anesthetic
In the first half of the 20th century, Avertin was also used in humans as a general anesthetic or basal narcotic to induce unconsciousness prior to the administration of other anesthetic agents. It was administered rectally as a retention enema or by intravenous injection.  Its rectal use was particularly favored for pediatrics, head or neck surgery, or in mentally unstable or anxious patients. Electrophysiology studies showed that tribromoethanol acts as a positive allosteric modulator of the inhibitory GABAA and glycine receptors, a mechanism similar to that seen with the related compound 2,2,2-trichloroethanol. Bromal hydrate (2,2,2-tribromoethanol-1,1-diol), a compound also recognized to produce general anesthesia in animals, is metabolized to tribromoethanol.

Polymerization initiator
Tribromoethanol can be used as a functional polymerization initiator for the introduction of α-hydroxyl groups in poly(methyl methacrylate) (PMMA) and poly(n-butyl acrylate) (PBAK).

Chemistry

Photolysis
Tribromoethanol should be kept refrigerated and in the dark, to prevent decomposition by light into hydrobromic acid and possibly 2,2-dibromoacetaldehyde or glycolic acid.

Champaign Aviation Museum. The Champaign Aviation Museum is an aviation museum in Urbana, Ohio. It is situated on the north end of Grimes Field municipal airport, roughly a mile from central Urbana. The museum is known primarily for its ongoing restoration of a B-17 Flying Fortress to flying condition. It is also a component of the National Aviation Heritage Area, a federally designated heritage area primarily centered around sites pertaining to the Wright brothers.

History
The museum began with the purchase of the wreckage of a JB-17G/model 299Z, a B-17 engine testbed variant with a fifth engine mounted on the nose, and several other parts sourced from various B-17s. The parts and pieces arrived at Grimes Field in November 2005. Restoration work started on the aircraft by volunteers at the south end of the airport soon after. The museum was established as a 501(c)(3) non-profit organization in 2008, the same year a North American B-25 Mitchell was purchased. The next year the museum purchased a C-47 and a former waterbomber A-26. Work continued on the B-17 at the south end until 2010 when a purpose built hangar was completed and the B-17 project as well as the newly acquired aircraft were moved into it. In August 2011, the museum recovered the remains, primarily the empennage, of a B-17G wreckage from Talkeetna, Alaska for use in the restoration. In November 2018, a Grumman C-1 Trader in flying condition was donated to the museum. Then a month later, in October, ground was broken on a project adjacent to the hangar to expand the museum by , and in late 2019 half of the expansion was completed.

Aircraft
The museum's collection consists of primarily vintage military aircraft, but also includes several civilian aircraft.

Exhibits 
In 2010 the museum began displaying an exhibit in their main hangar on Women Airforce Service Pilots (WASPs) and how they helped with the war effort.

In 2019 a 1941 Crosley convertible was donated to the museum and is on display in the museum's lobby.

The museum received a grant from the Ohio History Connection to complete a display about WASPs in 2022.

Cikapundung River. The Cikapundung River divides the city of Bandung, in West Java, Indonesia. The river flows from its headwaters in Lembang on the northern edge of the city, to the south, where it empties into the Citarum River.

The name Cikapundung is derived from the Sundanese language, and means river (ci, cai: water) and the name of a type of fruit: kapundung or kepundung (Baccaurea racemosa).

Despite being one of the main sources of Bandung's water supply, the river is classified as heavily polluted. Domestic waste, including human waste and detergents, is the main source of pollution as more people are living along the river banks. Other sources of pollutants are industry agriculture and farming.

Dorico. Dorico () is scoring software for macOS, Windows and iPadOS. Along with Finale and Sibelius, it is one of the three leading professional-level music notation programs. Dorico is developed by Steinberg, a subsidiary of Yamaha, and its development team consists of most of the former core developers of a rival software, Sibelius.

History 
After the developers of Sibelius were laid off in a 2012 restructuring by their corporate owner, Avid, most of the team were re-hired by a competing company, Steinberg, to create a new scorewriter.

The project was unveiled on 20 February 2013 by the Product Marketing Manager, Daniel Spreadbury, on the blog Making Notes, and the software was first released on 19 October 2016.

The program's title Dorico was revealed on the same blog on 17 May 2016. The name honours the 16th-century Italian music engraver Valerio Dorico (1500 – c. 1565), who printed first editions of sacred music by Giovanni Pierluigi da Palestrina and Giovanni Animuccia and pioneered the use of a single impression printing process first developed in England and France.

The iPad version was released on 28 July 2021, offering most of the functionality of the desktop app. It was the first major desktop scorewriter application to be made available on a mobile platform, however Sibelius also offers a mobile version.

In August 2024, when the rival scoring software Finale was discontinued after 35 years, its company President Greg Dell’Era recommended switching to Dorico, calling it the “new future of the industry”. He said: “Many have competed with Finale over the past four decades… but when Dorico launched in 2016, it set a brand new bar for the industry".

Features 
Dorico is known for its stability and reliability in creating aesthetically pleasing scores and its intuitive interface. User feedback influences Dorico's feature design, and the development team actively use the forum and Facebook group.

Automation 
Reviews have claimed that Dorico has become more efficient than other notation software. For example, a signature time-saving feature is its automatic creation of instrumental part layouts. Another signature feature is its automated condensing, where it combines multiple players' parts onto a single staff, such as for a conductor's score.

Keyboard input 
Dorico natively supports note input entirely from the computer keyboard without the need to use the mouse. It also supports MIDI input from a piano keyboard.

SMuFL music fonts 

The Standard Music Font Layout (SMuFL) standard was created by the Dorico development team at Steinberg. It provides a consistent standard way of mapping the thousands of musical symbols required by conventional music notation into a single font that can be used by a variety of software and font designers. It was first implemented in MuseScore, then in Dorico's first release and in Finale.

Continuous analytics. Continuous analytics is a data science process that abandons ETLs and complex batch data pipelines in favor of cloud-native and microservices paradigms. Continuous data processing enables real time interactions and immediate insights with fewer resources.

Defined 
Analytics is the application of mathematics and statistics to big data.  Data scientists write analytics programs to look for solutions to business problems, like forecasting demand or setting an optimal price. The continuous approach runs multiple stateless engines which concurrently enrich, aggregate, infer and act on the data. Data scientists, dashboards and client apps all access the same raw or real-time data derivatives with proper identity-based security, data masking and versioning in real-time.

Traditionally, data scientists have not been part of IT development teams, like regular Java programmers. This is because their skills set them apart in their own department not normally related to IT, i.e., math, statistics, and data science.  So it is logical to conclude that their approach to writing software code does not enjoy the same efficiencies as the traditional programming team. In particular traditional programming has adopted the Continuous Delivery approach to writing code and the agile methodology. That releases software in a continuous circle, called iterations.

Continuous analytics then is the extension of the continuous delivery software development model to the big data analytics development team.  The goal of the continuous analytics practitioner then is to find ways to incorporate writing analytics code and installing big data software into the agile development model of automatically running unit and functional tests and building the environment system with automated tools.

To make this work means getting data scientists to write their code in the same code repository that regular programmers use so that software can pull it from there and run it through the build process.  It also means saving the configuration of the big data cluster (sets of virtual machines) in some kind of repository as well.  That facilitates sending out analytics code and big data software and objects in the same automated way as the continuous integration process.
