Kenya Army Engineers Brigade. The mission of the Kenya Army Engineers Brigade is to support the Kenya Army in defence of the country against external aggression and to aid civil authority in humanitarian or civic projects.

Overview
The Engineers Brigade is divided into two battalions namely the 10th Engineers Battalion and the 12th Engineers Battalion. The unit is based at Thika and the School of Combat Engineering (SOCE) is the premier school for army engineers in the Kenya Army. The brigade has recently been deployed to Somalia and the frontier counties to assist in building barriers, clearing roads of improvised explosive devices, setting up base fortifications and building a border wall. They are also involved in numerous civic projects across the country such as construction of schools and drilling of water wells. The brigade can trace its formation back to 1965 when an engineer squadron made up of personnel from assault pioneers platoon was formed in Gilgil.

10 Engineers Battalion
The Kenya Army formed a Corps of Engineers in 1965 as an Engineer Company headquartered in Gilgil Barracks. The company was made up of a Headquarter troop, Field troop and a Plant troop totaling 120 men. The unit would later be moved to Nanyuki which still remains the battalion's current headquarters. The battalion would emerge in its current form in July 1979 with the formation of another battalion and it was subsequently renamed as 10 Engineers Battalion.

12 Engineers Battalion
The army saw the need to expand the engineers due to a number of expansion projects the Kenyan military was undertaking. These included expanding vast training areas and the Kenya Air Force range at Archer's Post in Samburu County. There was also the fact that the army had increased the number of infantry units and the decision was made to build up a second engineering battalion. A combat engineer troop that had been deployed to Nanyuki in 1978 was chosen and it was initially based at Archers Post before being relocated to Thika.

Davemaoite. Davemaoite  is  a high-pressure calcium silicate perovskite (CaSiO3) mineral with a distinctive cubic crystal structure. It is named after geophysicist Ho-kwang (Dave) Mao, who pioneered in many discoveries in high-pressure geochemistry and geophysics.  

It is one of three main minerals in Earth's lower mantle, making up around 5–7% of the material there. Significantly, davemaoite can host uranium and thorium, radioactive isotopes which produce heat through radioactive decay and contribute greatly to heating within this region giving the material a major role in how heat flows deep below the Earth's surface.

Davemaoite has been artificially synthesized in the laboratory, but was thought to be too extreme to exist in the Earth's crust. Then in 2021, the mineral was discovered as specks within a diamond that formed between 660 and 900 km beneath the Earth's surface, within the mantle. The diamond had been extracted from the Orapa diamond mine in Botswana. The discovery was made  by focusing a high-energy beam of X-rays on precise spots within the diamond  using a technique known as synchrotron X-ray diffraction. Subsequently, a reappraisal of the data from the Orapa diamond and its inclusion cast doubt on the attribution to calcium silicate perovskite. Instead, the data were reinterpreted in terms of a diamond from the shallow part of the mantle with inclusions of minerals commonly found in microinclusions. 

Calcium silicate is found in other forms, such as wollastonite in the crust and breyite in the middle and lower regions of the mantle. However, davemaoite can exist only at very high pressure of around 200,000 times that found at Earth's surface.

ArtemiFlow. ArtemiFlow is a biotechnology Potsdam-based company founded in 2012 by Peter Seeberger. The company produces and sells drugs containing the active ingredient artemisinin from Artemisia annua and its derivatives to fight malaria, cancer and other diseases. As of 2019, Adam Maust is the CEO of ArtemiFlow.

Production process 
ArtemiFlow is one of Peter Seeberger's companies for the production of low-cost medicines. With his team, he developed a process to produce artemisinin in large quantities in a cost-effective and environmentally friendly way, especially to meet the needs of developing countries. This was an innovative method as an alternative to Sanofi's genetic engineering one. Artemiflow developed a reactor for novel artemisinin production and developed higher-yielding plants in Kentucky in collaboration with the University Plants with higher yields.The new chemical production process is the first example of how not only the starting materials for making a drug or natural product are derived from plants. The catalyst, the tool that drives the reaction, also comes directly from plants.For developing the new process, Seeberger, Kerry Gilmore, and Andreas Seidel-Morgenstern were awarded the 2021 Science Prize for "Affordable Green Chemistry" by the American Chemical Society.

Development 
Initial difficulties were the large-scale implementation of the manufacturing process, the cultivation of annual mugwort in Vietnam and the financing of the start-up. According to the first CEO Dirk Pohlmann, the company was hoping for support from the Bill and Melinda Gates Foundation. The latter supported competing products from the Sanofi company made from genetically modified yeast. According to Pohlmann's account, the foundation's monopoly position in funding the international fight against malaria made it difficult for ArtemiFlow to gain a foothold. In addition, simply announcing synthetic production dropped prices for producers, so less artemisinin was expected to be produced.

Partnerships 
ArtemiFlow partnered with the University of Kentucky in 2018. Researchers at the university grew Artemisia annua, the plant that fights malaria, as part of the partnership. In 2020, the university and Artemiflow partnered on a clinical study to test the plant and its anti-cancer effects.

COVID-19 
Production on the potential use of artemisin against COVID-19 was controversial, in part because of possible conflicts of interest owing to Seeberger's leadership of ArtemiLife. The critical article in the SZ was answered by an article in the German magazine Focus.

Silver chlorite. Silver chlorite is a chemical compound with the formula AgClO2. This slightly yellow solid is shock sensitive and has an orthorhombic crystal structure.

Preparation
Silver chlorite is prepared by the reaction of silver nitrate and sodium chlorite:

Reactions and properties
If normally heated, it explodes violently at 105 °C:

If heated very carefully, it decomposes at 156 °C to form silver chloride. It can also decompose to silver chlorate is chlorous acid is present.

Silver chlorite reacts explosively with various substances such as sulfur and hydrochloric acid, forming silver chloride. It also gets reduced by sulfur dioxide, and reacts with sulfuric acid to form chlorine dioxide. This compound explodes in contact with iodomethane and iodoethane.

Silver chlorite complexes
Silver chlorite can react with anhydrous ammonia to form triammonia-silver chlorite:

Vivacity 24. The Vivacity 24 is a British trailerable sailboat that was designed by Alan F. Hill as a cruiser and first built in 1969.

Production
The design was built by Russell Marine in the United Kingdom, starting in 1969, but it is now out of production.

Design
The Vivacity 24 is a recreational keelboat, built predominantly of glassfibre, with wood trim. It has a masthead sloop rig; a spooned, raked stem; an angled transom, a skeg-mounted rudder controlled by a tiller and a fixed fin keel or optional twin keels. It displaces  and carries  of iron ballast.

The boat has a draft of  with the standard keel and  with the optional twin keels.

The boat may be fitted with an inboard engine or a small  outboard motor for docking and manoeuvring.

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin and drop-down dinette table in the main cabin. The galley is located on the port side just forward of the companionway ladder. The galley is U-shaped and is equipped with a stove and a sink. The head is located just aft of the bow cabin on the starboard side. Cabin headroom is .

The design has a hull speed of .

Operational history
In a 2010 review Steve Henkel wrote, "the Vivacity 24 is a relatively heavy and somewhat under-rigged coastal cruiser. Best features: The twin keeler sails and tracks well downwind. Worst features: Several owners say their Vivacity 24s are sluggish to windward and tend to pound in a chop. They also point out that their boats are under rigged for light air sailing conditions, and can benefit from additional light weather cruising chutes and foresails to keep them moving. But fully rigged in winds above 20 knots they can develop a nasty weather helm. Moral: reef at 15 knots."

In a 2017 review Go Sail noted, "the Vivacity 24 is a small solidly built small cruiser offering good safe coastal cruising with reasonable performance and well laid out accommodation for her size."

Doyleite. Doyleite is a rare aluminum trihydroxide mineral named in honor of its discoverer, the Canadian physician Earl Joseph (Jess) Doyle.  It was first definitively described in 1985 (although a partial description was published in 1979) and it is approved by the IMA. It was described from Mont Saint-Hilaire, where it is extremely rare.

Properties 
Doyleite grows in small square tabular crystals, which form rosettes. Individual crystals can grow up to 8 mm. The mineral has a layered micaceous structure. This pinacoidal mineral mostly consists of oxygen (61.53%) and aluminum (34.59%), but also contains hydrogen (3.88%). Doyleite does not display any radioactive properties. At room temperature, doyleite is not soluble in a 1:1 ratio of sulfuric acid, hydrogen chloride, and nitric acid. Crystals are tabular on (010), which show forms of {010}, {101}, and {10}. Occasionally, however, it shows forms of {001} and {100}. Some specimens are coated with a thin film of dark brown amorphous material, thought to be iron oxide. The mineral has been determined to be triclinic by a three-dimensional single-crystal diffraction study. It has a bilayer structure, similar to its polymorphs. There is good correspondence between the AFM images of doyleite's (010) surface and the calculated structure. The hydroxyl group's intra-layer interactions show no Raman scattering in contrast to its polymorphs. The P1 j structure model is slightly more unstable than the non-centrosymmetrical P1 structure model. The layered structures are similar to those found in one of its polymorphs, bayerite. The difference is within the interlayer shift vectors only. Doyleite is the least stable of the polymorphs.

Mining and environment 
Doyleite is associated with fluorite, zircon, pyrite, albite, siderite and molybdenite. It is the polymorph of gibbsite, nordstrandite, bayerite and UM1990-28-OHF:Al. Doyleite has two type localities, one is the Poudrette and Francon quarry, Canada; the other is Mont Saint-Hilaire, also in Canada. It is a late-stage hydrothermal mineral, and can form hydrothermal mineral deposits. Doyleite is found lining vugs in veins in nepheline syenite. It also occurs with calcite and pyrite in albitite veins.
