Californium(III) polyborate. Californium polyborate is a covalent compound with formula Cf[B6O8(OH)5]. In this compound the californium is in a +3 oxidation state. This compound is the highest atomic number borate with a visible solid phase. Heavier elements than californium decay too fast to make macroscopic amounts of solid crystals.

Californium polyborate is unusual in that californium is covalently bound to the borate. Californium was expected to resemble lanthanide elements in being highly ionic. The polyborate anion is polarisable and flexible. The 5f, 6d, 7s, and 7p orbitals of californium are all involved on the bonding. Most valence electrons are in the 5f orbital, and a significant fraction () in the 6d orbital, and smaller fractions of one electron are in the 7s and 7p orbitals.

Formation
Californium(III) polyborate can be made by autoclaving a californium(III) chloride solution in water with excess boric acid for a week at 240°C. This is then cooled slowly to room temperature for another three days. Water dissolves excess boric acid to leave insoluble crystals of the borate.

Properties
The californium(III) polyborate solid undergoes a green fluorescence of 525 nm with ultraviolet light of wavelengths 365 or 420 nm. There is also an invisible near infrared fluorescence at 1020 nm induced by green light at 546 nm.

Safety
Californium polyborate is dangerous because of the radioactivity of californium and its decay daughter curium.  Between them these elements emit α particles, gamma rays and neutrons.

D5SICS. d5SICS is an artificial nucleoside containing 6-methylisoquinoline-1-thione-2-yl group instead of a base.

It pairs up with dNaM in a hydrophobic interaction. It was not able to be removed by the error-correcting machinery of the E. coli into which it was inserted. The pairing of d5SICS–dNaM is mediated by packing and hydrophobic forces instead of hydrogen bonding, which occurs in natural base pairs. Therefore, in free DNA, rings of d5SICS and dNaM are placed in parallel planes instead of the same plane. The d5SICS-dNaM pairing replaced an older dNaM-dTPT3 pairing.

Daniel Dalgleish. Daniel Cameron Dalgleish (1 February 1827 – 18 February 1870) was a Scottish-born Australian politician.

He was born in Alloa to exercise supervisor Adam Dalgleish. He was apprenticed to an engineer in Edinburgh and then moved to London, where it was difficult to find work due to his membership of the Amalgamated Society of Engineers (ASE). In 1852 he moved to Sydney with others in a similar situation, and on the voyage they formed the first overseas branch of the ASE, which later became the Amalgamated Engineering Union. In 1860 he was elected to the New South Wales Legislative Assembly for West Sydney, but he was defeated in 1864. In 1865 he lost a libel case to Thomas Holt. He was subsequently an inspector for the Steam Navigation Board. Dalgleish died in Sydney in 1870.

Media Block. A Media Block or Integrated Media Block (IMB) is a component in a digital cinema projection system.  Its purpose is to convert the Digital Cinema Package (DCP) content into data that ultimately produces picture and sound in a theater in compliance with DCI anti-piracy encryption requirements.

Terminology

DCI specification allows for two different security system architectures.

In the first the Media Block is outside of the projector. This design is simply referred to as a "Media Block" and is typically a device attached directly to the motherboard of a Digital Cinema server. The media block is usually connected to the projector by dual-link SDI cables. Such media block is limited to processing 2K output, downscaling 4K DCPs if necessary.

The second architecture describes an "Integrated Media Block". This refers to a device attached and integrated directly into the projector, which receives image data from the server, usually via a cat6 Ethernet connection. They can process 2K and 4K output.

Some hardware implementations integrate the entire server on a single board and are able to work both as a MB as well as an IMB.

Security Features

All security functions are contained within a Secure Processing Block (SPB), a tamper-proof physical device.

Upon ingestion into a DCP server, Key Delivery Messages (KDM) are stored on flash memory in the media block or IMB. A KDM is written to enable the playback of a specific DCP during a specific time window and on a specific media block or IMB, identified by its serial number during the authoring process. Media blocks and IMBs also contain a secure clock that is set in the factory cannot be altered by the end user, which the DCP servers to which they are attached use to determine showtimes. The secure clock prevents theaters from showing encrypted movies outside the times authorized by the KDM (e.g. after it has expired) by simply changing the date and time in the server's BIOS. Media blocks and IMBs also typically include anti-tamper devices, designed to self-destruct the unit if unauthorized modification of its hardware, software or secure clock is attempted.

Émile Cheysson. Jean Jacques Émile Cheysson (Nîmes, 18 May 1836 – Leysin, 7 February 1910) was a French engineer, designer of roads and bridges, and social reformer, who made a career as in industry and in the French administration. He has played an important role in the institutionalization of statistics in France, and has published a series of graphic statistical albums for the French Ministry of Public Works, which are considered as extraordinary examples of data visualization. At the same time, he was a disciple of Frédéric Le Play and resumed sociological work and his monographic method.

Cheysson was a graduate of the École Polytechnique, where he graduated in 1854. Under Frédéric Le Play he participated in the organization of the Universal Exhibition of 1867. He was director of the Le Creusot factories in Le Creusot from 1871 to 1874, professor of political and social economics at the Ecole libre des sciences politiques and professor of industrial economics at the École des mines, and then inspector general of Ponts et Chaussées.

Machina (company). Machina is a clothing brand company specializing in wearable technology based in Mexico City and San Francisco, accelerated by Highway1 and Wayra.

The company attempted to make a MIDI controlling jacket. A 2012 review in TechCrunch called the jacket "a cool concept and an interesting and kinetic way to trigger and control beats and sounds." The company was founded in 2011 by Linda Franco, Antonio Perdigón, and Daniel Fernández de Córdova.

A Kickstarter project in 2013 produced a prototype, with a delay of almost a year behind the projected delivery date. Since then, there have been no substantial updates and the announced open-source hardware has not materialized. As of 2017, the company has been developing developing OBE, a jacket for virtual reality with accelerometers and vibration motors.

Bio-bean. Bio-bean was a private company that industrialised the process of recycling waste coffee grounds into advanced biofuels and biomass pellets.

The company was located in London, England, and built the world's first waste coffee recycling factory in Cambridgeshire. It was founded in 2013 by Arthur Kay. In 2014 the company was awarded £400,000 as the winner of the Postcode Lottery Green Challenge contest. In 2022 after an assessment by B Corp, bio-bean was announced as the B Corp Best in the World Environment, with an overall score of 99.1.

History
Bio-bean was conceived while Arthur Kay was still an architecture student at The Bartlett, University College London (UCL).  Faced with the challenge of designing a coffee shop and roastery, Arthur realised that coffee was being wasted everywhere and set up bio-bean to recycle waste coffee grounds into advanced biofuels. 

Bio-bean collected waste coffee grounds from hundreds of coffee shops, restaurants, office blocks, and coffee factories.

His idea won awards and support from the Mayor of London, UCL, Tata, Santander, and Shell.  bio-bean became a part of the Ellen MacArthur Foundation CE100, and its products were exhibited at The Science Museum. The company was also awarded funding from Innovate UK. Bio-bean's London collection service was launched by Mayor Boris Johnson and Conservative MP Zac Goldsmith, and its 40,000 sq ft factory was opened in 2015 with the capacity to process 50,000 tonnes per year.

In 2015 Kay became the youngest-ever Guardian Sustainable Business Leader of the Year. In 2016 Bio-bean won the Virgin Media Business VOOM Grow category. In 2017 bio-bean collaborated with Shell,  Argent Energy, and Transport for London to create biodiesel from used coffee grounds,   which has been used to power London's buses.  The campaign achieved a global reach of 11.8 billion through purely earned media activation.    The campaign was featured in global media outlets such as the BBC, Bloomberg, New York Times, The Independent, among many others. In 2017 according to reports, Bio-bean launched its ad campaign after winning Richard Branson's Virgin Voom competition.

In March 2023 Bio-bean collapsed following strong domestic inflation and a factory fire.  In July 2023 Envar Composting Ltd, a large UK-based bioenergy company, acquired Bio-Bean's assets.

Biofuel
Bio-bean's products were second-generation biofuels. Pellet fuels, namely biomass pellets, from waste coffee grounds, are burned in biomass boilers as a sustainable, local renewable heat alternative.  bio-bean also produced briquettes and barbecue charcoal from waste coffee grounds   bio-bean conducted extensive research and development into biodiesel,   biochemicals, and further uses for waste coffee grounds and other organic waste streams.

Cowardin classification system. The Cowardin classification system is a system for classifying wetlands, devised by Lewis M. Cowardin et al. in 1979 for the United States Fish and Wildlife Service.  The system includes five main types of wetlands:
 Marine wetlands- which are areas exposed to the open ocean
 Estuarine wetlands- partially enclosed by land and also exposed to a mixture of fresh and salt water bodies of water
 Riverine wetlands- associated with flowing water
 Lacustrine wetlands- associated with a lake or other body of fresh water
 Palustrine wetlands- freshwater wetlands not associated with a river or lake.
The primary purpose of this ecological classification system was to establish consistent terms and definitions used in inventory of wetlands and to provide standard measurements for mapping these lands.

Traverse (trench warfare). In trench warfare, a traverse is an adaptation to reduce casualties to defenders occupying a trench. One form of traverse is a U-shaped detour in the trench with the trench going around a protrusion formed of earth and sandbags. The fragments or shrapnel, or shockwave from a shell landing and exploding within a trench then cannot spread horizontally past the obstacle the traverse interposes. Also, an enemy that has entered a trench is unable to fire down the length at the defenders, or otherwise enfilade the trench.

A traverse trench is a trench dug perpendicular to a trench line, but extending away from the enemy. It has two functions. One function is to provide an entry into the main trench. A second function is to provide a place for defenders to shelter and regroup should the enemy have penetrated into the main trench and be able to fire down the main trench's length.

On an approach trench, that is, a trench leading from the rear to the frontline or firing trench, defenders may construct an island traverse. With an island traverse, the approach trench splits to go around both sides of a traverse before coming together again. 

Lastly, a flying or bridge traverse is a sandbagged covering for a stretch of trench to block shrapnel or shell fragments from entering the trench.

Ubungo II Thermal Power Station. Ubungo II Thermal Power Station was an extension to the Ubungo I Power Station and began commercial operations in 2012. The power-plant is located in  Ubungo of Ubungo District  in Dar es Salaam Region of Tanzania. The plant has an installed capacity of .

History
Symbion Power already had extensive electrification contracts within Tanzania. Symbion helped build a power plant in May 2011 and was operational in under one month. The introduction of the Symbion Power Plant to the Tanzanian electricity helped alleviate the problems experienced in the country caused by severe power shedding. Symbion's projects were funded by the Government of the United States through the Millennium Challenge Corporation.

The Power plant was handed over to the Tanzania Electric Supply Company in June 2011 and TANESCO planned to convert the current power plant to a permanent facility. TANESCO awarded Jacobsen Elektro AS from Norway to construct the Ubungo II Gas Based Power Plant. Jacobsen ordered three SGT-800 gas turbines from Siemens with a total capacity of .

The Ubungo II Gas Based Power Plant was constructed in 14 months and began operations on 1 July 2012. Unlike the Ubungo I plant, this plant is owned and operated entirely by TANESCO. However the gas for this plant is still obtained by Songas.

Eric Webb. Eric Norman Webb  (1889–1984) was an engineer known for his role as chief magnetician on the Australasian Antarctic Expedition.

Biography
Eric Norman Webb was born in Christchurch, New Zealand in 1889. He studied civil engineering at the University of Canterbury and worked at the Melbourne Observatory carrying out observations for the Carnegie Institution for Science.

At age 22 he was selected as chief magnetician on Sir Douglas Mawson's Australasian Antarctic Expedition. Part of his role while based at Cape Denison was to take daily measurements from the Magnetograph House, which he carried out daily regardless of the sometimes difficult conditions. He took part in a sledging journey with Edward Frederick Robert Bage and Frank Hurley to the South Magnetic Pole, a round trip of 960km. Both Cape Webb and Webb Subglacial Trench are named after him.

Webb served in the British Army during World War I. He enlisted in the 7th Field Company Engineers and embarked from Sydney on 30 November 2015 on board HMAT A23 Suffolk. He received the Military Cross, Distinguished Service Order, 1914–15 Star, British War Medal and Victory Medal, and was mentioned in despatches. The citation for his MC, appearing in The London Gazette in February 1919, reads as follows:

He later worked in hydroelectric projects including the Churchill Falls Generating Station (then known as Hamilton Falls) in Labrador, Canada. He visited Australia in 1974 and was interviewed for ABC Television about his role in the Australasian Antarctic Expedition.

Eric Webb was the last surviving member of the Australasian Antarctic Expedition. He died on 23 January 1984.

Dave Needle. David Lewis Needle (December 17, 1947 – February 20, 2016) was an American computer engineer. He was a key engineer and co-chief architect in the creation of the Amiga 1000 computer with Jay Miner, Dave Morse, and RJ Mical. He was one of the main designers and developers of the custom chips of the Amiga computer. Later he co-invented the Atari Lynx and the 3DO Interactive Multiplayer with Morse and Mical.

A 1995 article in Next Generation commented: "It's true that of the machines that Mical and Needle have created, only the Amiga has been a true global mass market hit ... But it's only fair to put forward the argument that this is down to the marketing of the machines rather than the quality of the product."

Dave Needle died on February 20, 2016.
