Isethionates. Isethionates are esters of long-chain aliphatic carboxylic acids (C8 – C18) with isethionic acid (2-hydroxyethanesulfonic acid) or salts thereof, such as ammonium isethionate or sodium isethionate. They are also referred to as acyl isethionates or acyloxyethanesulfonates.

Like the taurides, isethionates are a class of particularly mild anionic surfactants which, unlike ordinary soaps, retain their washing-active properties even in hard water. Isethionates are obtained on an industrial scale reacting mixtures of carboxylic acids with salts of isethionic acid under acidic catalysis e. g. with methanesulfonic acid. The mixtures of carboxylic acids are obtained from the hydrolysis of animal fats (tallow) or vegetable oils, preferably coconut oil, but also palm oil, soybean oil or castor oil.

Isethionates are solids which are often mixed with fatty acids (up to 30% by weight) to lower their freezing point. Despite its low water solubility (100ppm at 25 °C), the lower-priced sodium cocoylisethionate has found more widespread use than its well water-soluble ammonium salt (> 25 wt.% at 25 °C). To solubilize the sparsely soluble isethionates and taurides, the formation of mixtures with amphoteric surfactants (such as cocamidopropyl betaine) are proposed. From such mixtures, it is possible to prepare liquid, clear and transparent aqueous concentrates which are liquid at room temperature.

Isethionates are characterized by excellent skin compatibility, excellent foaming (even in hard water), good cleansing properties and a pleasant skin feel. They are non-toxic and readily biodegradable.  However, in contrast to the taurides, they are not long-term stable outside a pH range of 5 to 8. Isethionates are used in solid soaps (so-called syndet bars) and in other personal care products such as lotions, washing and shower gels, shampoos, liquid soaps, shaving creams, and other cosmetic and dermatological preparations.

EURO Gold Medal. The EURO Gold medal of the Association of European Operational Research Societies (EURO) is the highest distinction within Operations Research (OR) in Europe.
The prize was first awarded to Hans-Jürgen Zimmermann in 1985.

The medal is awarded at EURO-k Conferences, which usually take place twice every three years.
It is granted to an individual or a group for an outstanding contribution to the field of Operations Research.
The Prize is intended to reflect contributions that have stood the test of time, and hence it is awarded for a body of work, rather than a single piece.
The award is a medal in gold, a diploma, and a fee waiver for all future EURO-k conferences.

The Ocean Agency. The Ocean Agency is an international nonprofit organization dedicated to marine conservation. Currently, The Ocean Agency is focused on coral reef conservation.

Projects
In 2012, The Ocean Agency launched the XL Catlin Seaview Survey to create an underwater Google Street View using the Seaview SVI and Seaview SVII 360-degree underwater cameras. From 2013 to 2016, The Ocean Agency visited more than 26 countries and surveyed over 1,000 km of reef area, taking over a million 360-degree images with the cameras.

In 2014, The Ocean Agency started recording the 3rd Global Coral Bleaching Event, which became the subject of the Netflix Original Documentary Chasing Coral. The documentary premiered at the 2017 Sundance Film Festival and was released on Netflix in July 2017.

In 2016, The Ocean Agency ideated 50 Reefs — a global plan to save coral reefs. This initiative was launched in early 2017 with the support of Bloomberg Philanthropies, The Tiffany & Co. Foundation and the Paul G. Allen Family Foundation. Its aim was to bolster conservation action in key geographies identified as being less vulnerable to climate change and having the best chance of repopulating other reefs over time.

The Ocean Agency was appointed to coordinate International Year of the Reef 2018 by the International Coral Reef Initiative, working in collaboration with the United Nations Environment Programme. The Ocean Agency has launched a bank of coral reef imagery, Year of the Reef Image Bank, to supply imagery to media outlets, organizations and citizens who want to help promote the Year of the Reef.

Process–architecture–optimization model. Process–architecture–optimization is a development model for central processing units (CPUs) that Intel adopted in 2016. Under this three-phase (three-year) model, every microprocessor die shrink is followed by a microarchitecture change and then by one or more optimizations. It replaced the two-phase (two-year) tick–tock model that Intel adopted in 2006. The tick–tock model was no longer economically sustainable, according to Intel, because production of ever smaller dies becomes ever more costly.

Friction hydro pillar processing. Friction hydro-pillar processing  (FHPP) is a solid-state joining technology which can be used for filling of surface and sub-surface cracks in thick metals. For example, FHPP was attempted for the first time to repair cracks in space shuttle external components of high-strength aluminum alloys. FHPP is also considered in repairing surface cracks in steam turbine rotors of a high-strength, high-temperature-resistant steel (grade 26NiCrMoV14-5) (Ref). Alternative methods such as fusion welding processes for in-service repairing of cracks in components of these high-strength steels remained difficult because of their high hardenability and mandatory need of pre-heating and post-weld heat treatment. In contrast, initial FHPP trials could achieve joint strengths up to 90% of the base materials in high-strength steel components, especially those used for petrochemical and thermal power plants. In particular, pressurized pipes and vessels of AISI 4140 steel are widely used in the power generation, oil and gas, and petrochemical industries. Initial studies on FHPP of this alloy have showed promising results. 

Fusion welding of AISI 4140 steel is usually recommended in annealed condition and with low hydrogen diffusible filler wires of relatively lower strength, e.g., ER70S-2 and ER80S-D2, because of the very high hardenability of Cr-Mo steels. Careful pre-heating and post weld heat treatments procedures must be followed to avoid cold cracking, reduce residual stresses and decrease impairment of HAZ properties in fusion welding of Cr-Mo and high carbon steels. Since FHPP is a solid-state joining process, several of the aforementioned issues can be alleviated. A systematic analysis of FHPP of Cr-Mo and Carbon steels is therefore needed but scarce in the literature.

An increase in stud force led to faster plastic flow of the stud and therefore reduced the overall processing time and peak temperature. However, the effect of the reduced processing time and lower peak temperature on the joint properties were not well addressed in the literature. Improper selection of the stud force often led to "lack of filling" defects near the crack hole bottom in FHPP of high-strength steels. FHPP is also attempted under the water to reduce the peak temperature in components of high-strength line pipe X65 steels (Ref). However, the resulting joint exhibited a full martensite structure due to higher cooling rates. A fairly uniform hardness distribution across the joint was reported in FHPP of C-Mn steel especially at lower stud forces (Ref). Although these studies provided an insight into FHPP of steels, a quantitative understanding of the effect of process variables on the temperature field, cooling rate and resulting joint hardness distribution remained scarce in FHPP of high-strength steels.

Aeromarine 90hp. The Aeromarine 90 hp was the first aircraft motor built by the Aeromarine Plane and Motor Company in 1914. In that year, Aeromarine had acquired the patents and manufacturing rights to the aircraft and engines of the Boland brothers. Although the Boland brothers didn't make a 6-cylinder engine, their V-8's all used the unusual concentric valve that is used in this engine. In spite of its model name, this engine only produced  at 1,400 rpm

Coates Hire. Coates is an Australian equipment rental company operating in all Australian states and territories. It is a fully owned subsidiary of Seven Group Holdings. As of 2023, Coates is valued at A$1.87 billion of hire equipment at original cost.

History
Coates was founded in 1885 as a small engineering company in Melbourne. It diversified into equipment hire in the years following World War II when a vibratory roller was purchased and lent to potential customers on a Try Before You Buy policy. Coates was listed on the Australian Securities Exchange (ASX) in 1955. In 1972 Coates was purchased by Australian National Industries.

In 1993, it commenced operations in Indonesia. In August 1996 it was re-listed on the ASX. In 2002, Wreckair was acquired from Brambles Limited.

In January 2008, it was delisted from the ASX when acquired by private investors The Carlyle Group and the National Hire Group. The hire businesses of Coates and the National Hire Group were merged to consolidate the two largest hire companies in Australia.

On 25 October 2017, Seven Group Holdings acquired the remaining 53% from The Carlyle Group as well as from minority owners. Seven Group Holdings had first invested in Coates, alongside The Carlyle Group and management in 2008 through its WesTrac subsidiary.

On 10 June 2021, the company rebranded from Coates Hire to Coates.

Sponsorships
Coates has been a regular sponsor of Supercars teams and events. It was title sponsor for Nick Percat’s 2012 Development Series, 2013 Australian Carrera Cup Championship and 2014 V8 Supercars Championship campaigns. It was previously the title sponsor for various Supercars events including the Ipswich SuperSprint, Sydney 500, Supercars Challenge, Melbourne 400 and the Newcastle 500.

Guinea-Bissau Air Force. The Guinea-Bissau Air Force () is the air force arm of the military of Guinea-Bissau.

History
On leaving Bissalanca by 1973–74, the Portuguese Air Force left three North American T-6Gs, nine C-47 Skytrains, two Dornier Do 27s, and two Aérospatiale Alouette IIIs. After achieving independence from Portugal, the air force was formed by officers returning from training in Cuba and the USSR. The FAGB was re-equipped with eight or ten MiG-17Fs and two MiG-15UTIs supplied by East Germany and the Soviet Union.

In 1978 France provided more aircraft aid in the form of a Reims-Cessna FTB.337 for coastal patrol and a surplus Alouette II.  A Dassault Falcon 20F was donated by the Angolan government but was soon sold to the USA. In 1978, the Soviet Union provided a Mil Mi-8T helicopter as aid. In 1986, the Soviets delivered seven MiG-21bis fighters and MiG-21UM trainer aircraft.

The force's title was changed to Força Aérea da Guiné-Bissau (FAGB) after the outbreak of the civil war in 1998. Cooper and Weinert state 'when sighted for the last time in...1991, most of the [MiG] fleet was in 'storage' inside several hangars on the military side of Bissalanca IAP (Osvaldo Vieira International Airport), and in a deteriorating condition.'

By 2011, Guinea-Bissau had two 'probably' non-operational MiG-17s and a MiG-15UTI, while its MiG-21s and fixed-wing transport aircraft were withdrawn from service, leaving only an Aérospatiale Alouette II and a couple of Alouette IIIs for liaison.
