Bombardier 7.6. The Bombardier 7.6 is a Canadian sailboat that was designed by Ron Holland as a racer and first built in 1980.

Production
The design was built by Bombardier Limited in Canada between 1980 and 1983, with about 163 boats completed, but it is now out of production.

Design

The Bombardier 7.6 is a recreational keelboat, built predominantly of fibreglass. It has a fractional sloop rig, a raked stem, a slightly reverse transom, a transom-hung rudder controlled by a tiller and a fixed fin keel. It displaces  and carries  of lead ballast.

The boat has a draft of  with the standard keel fitted. The design is normally fitted with a small outboard motor of  for docking and maneuvering.

Several different port configurations were used during production, including a single and double side portlight.

The design has sleeping accommodation for five people, with a double "V"-berth in the bow cabin, an dinette table in the main cabin that converts to a double berth and an aft starboard quarter berth. Cabin headroom is .

The design has a PHRF racing average handicap of 165, with a low of 159 and a high of 171.

Operational history
In 2009 a Bombardier 7.6, named Gizmo, sailed by Marc Doedens and his father, Ric Doedens, won the overall Lake Ontario 300 competition.

In a 2010 review Steve Henkel wrote, "best features: She is quick and agile, and with her Ron Holland pedigree, she is apt to make the average around-the-buoys racer happy, while still serving the typical young sailing family as an overnight cruiser. Worst features: Her iron keel and thin hull may need more than the usual amount of maintenance to keep in first-class condition."

The Hunt (1950s Stanisław Lem short story). The Hunt () is a long unknown science fiction short story by  Stanisław Lem about a robot hunted by people. It superficially resembles another Lem's short story  The Hunt from  Tales of Pirx the Pilot, however the two are completely different. It was written before the Pirx story, probably in late 1950s. It was found in Lem's archives and published in Przekrój magazine in 2018. An English translation was published in  2019.

Plot
A runaway is chased by humans with dogs. As the story evolves, it becomes clear that it is a robot, an intelligent machine, one of many created by humans to be hunted. For this reason it was endowed with wit and strength and an ability to be afraid, so that it would run away and make a hunt interesting: "... a tangled plot full of surprises, a forest strategy, a duel of cunning, of tactics, including laying double trails, dodging, looping the scent back on itself, crossing white-water streams and aerial bridges formed by fallen trees".

A little girl helps him to hide, but eventually it turns out that her goal was to lay her hands on a gun and shoot the hunted robot herself.

Discussion
The manuscript of the story was found by Lem's secretary Wojciech Zemek several decades before the publication, but misled by the resemblance of both the title and the plot to the Pirx story, he filed it together with the drafts for the Pirx story.

It is well known that Lem was ruthlessly burning his unpublished works, and the researchers were puzzled why Lem kept this one. Stanisław Bereś attempts to explain this as follows.  Lem never wrote and seldom spoke about his life during World War II in Nazi-occupied Lwow. However one can decipher subtle hints about his experiences of that time in various Lem's works of fiction. Bereś points out an obvious parallel of the runaway's hopeless struggle for his life from The Hunt story, with the experience of the Jews during the Holocaust, including Lem's own. Therefore Bereś suggests that Lem felt overexposing himself in the story, therefore he set it aside and eventually wrote another, a more entertaining version and possibly forgot about the older manuscript.

The two versions  of The Hunt are very different. One is a story of Pirx chasing a damaged mining robot on the Moon struck by a meteorite and firing its laser at any detected motion. On the other hand, the rediscovered version is told from the point of view of the robot designed to be a prey, who is, "like a Roman gladiator, fighting the longest possible struggle for its miserable electronic life".

Difluorosilane. Difluorosilane is a gaseous chemical compound with formula SiH2F2. It can be considered as a derivative of silane with two hydrogen atoms replaced with fluorine.

Production
Difluorosilane can be made by fluorinating dichlorosilane with antimony trifluoride.  

3 SiH2Cl2 + 2 SbF3 → 3 SiH2F2 + 2 SbCl3

Some is also made in a reaction of silicon tetrafluoride with hydrogen

SiF4 + 2 H2 → SiH2F2 + 2 HF

Traces of difluorosilane are made when coal is burnt.

Properties
Difluorosilane is a gas with boiling point −77.8 °C, and a freezing point of −122 °C. It has no colour. The silicon–fluorine bond length in difluorosilane is 1.358 Å which is greater than that in fluorosilane but less than the length in trifluorosilane.

Reactions
In an electric discharge, hydrogen atoms are preferentially removed from the molecule and SiHF2SiHF2 is formed along with hydrogen.

2 SiH2F2 → SiHF2SiHF2 + H2

At elevated temperatures, difluorosilane can disproportionate by swapping hydrogen and fluorine atoms between molecules to form fluorosilane and trifluorosilane.

Use
Difluorosilane is used in dental varnish in order to prevent tooth cavities.

Difluorosilane is also used in chemical vapour deposition to deposit silicon nitride films.

Sisteplant. Sisteplant is a Spanish multinational company specializing in the automation and digitalization of industrial processes. It was founded in Bisay in 1984. It is headquartered in Madrid, with offices in Bilbao, Barcelona, Seville, Pontevedra, Valencia, Brazil, and Mexico.

History 
The company was created in 1984 by Javier Borda, an industrial engineer. From its beginnings until the mid-1990s, the company was involved in the technological transformation and optimization of the Basque automotive, steel, and shipbuilding industries. It introduced information technologies and computerized maintenance systems. It has also spread to other regions of Spain, and to other sectors of the economy, such as energy, agri-food, aerospace and public administration. The company promoted productivity improvements through the implementation of lean manufacturing.

In the mid-1990s, they moved from mass production to high-tech sectors with small series or one-off production, such as aeronautics; and began their international expansion with the help of Spanish Ibex companies, opening offices in Mexico (Santiago de Querétaro), Brazil (São Paulo)) and China (Xuhui, Shanghai district).

The company has developed projects in the automotive, aerospace, energy, food, pharmaceutical, public administration, logistics and infrastructure sectors, both nationally and internationally.

Since 2007, it has developed the Tecnoiplant model, a technological, digital and organizational roadmap for the factory of the future, using its own software systems (Prisma, Captor, Promind, and Itracker). The company has also incorporated artificial intelligence tools to its digital platform, which is called Manufacturing Intelligence.

Sisteplant is a family company. Its capital is in the hands of its president, Javier Borda. Its shareholders included the venture capital fund Talde, the IBV group and other managing partners who later withdrew.

Innovation and development 
Since its inception, the company has dedicated 20% of its turnover to the development of R&D&I projects in collaboration with the Basque Government, universities and research centres.

Together with Tecnalia, it has participated in innovative technological developments for the production of continuous CNT (carbon nanotube) sheets for the aeronautical and marine industries.

Vinyl sulfone dyes. Vinyl sulfone dyes are reactive dyes comprising a vinyl sulfone group as reactive group (a fiber-bonding site of the reactive dye, "reactive hook"). Due to the relatively high reactivity of the vinyl sulfone group with water (residual moisture, air humidity), it is present in many commercial products in a protected form. For protection, an ethylsulfonyl group is substituted with a leaving group. During the dyeing process under alkaline conditions, the vinyl sulfone group is released by an elimination reaction:

Formation of the vinyl sulfone group by alkaline elimination. R= alkyl or aryl radical, X=-OSO3H, -Cl

Chemical structure 
The vinyl sulfone reactive anchor is usually introduced into the reactive dye via an aromatic or aliphatic amine.

The oldest and most common intermediate is vinyl sulfone parabase ester (see image), an aniline substituted with a [2-(sulfooxy)ethyl]sulfonyl group. The vinyl sulfone parabase ester can be used as a diazo component in the preparation of azo dyes. A further possibility is the condensation reaction of parabase ester with a chlorine or fluorotriazine residue, which in turn can be linked to any chromophore via a further amino group. 

Possible variations result from further substituents on the aromatic ring - usually hydroxy, methyl or methoxy groups - or from the position of the amino relative to the vinyl sulfone group. In addition to the para-substituted compound, also meta- and orthosubstituted vinyl sulfone anilines are used.

If the vinyl sulfone group is introduced via a primary or secondary aliphatic amine, this is performed again by condensation with a halotriazine compound. An example is 2-[2-(2-chlorethylsulfonyl)ethoxy]ethanamine used in bifunctional reactive dyes in combination with a monofluoro or monochlorotriazine hook.

Dyeing process 
The vinylsulfone group reacts with the nucleophilic functional groups of the fibers by Michael addition to form a covalent ether bond:
Reaction of vinyl sulfone compounds with hydroxyl groups of cellulose (HO-CELL)
An unfavorable side reaction in the dyeing process is the conversion of the vinylsulfone group to the 2-(hydroxy)ethylsulfonyl group:
Reaction of vinylsulfone compounds with water/OH− during dyeing
The hydroxylated, unreactive dye has to be washed out during the post-treatment.

History 
The first dyestuffs with a [2-(sulfooxy)ethyl]sulfonyl group were patented in 1949 by the then Farbwerke Hoechst and marketed in the following years as wool dyestuffs under the brand name Remalan or as cotton dyestuffs under the brand name Remazol. From the early 1980s onwards, reactive dyes containing a monochlorotriazine anchor in addition to the vinylsulfone reactive group were produced by the dye manufacturers Sumitomo (brand name Sumifix Supra) and Hoechst AG. In 1988, Ciba-Geigy introduced double anchor dyes with a combination of a vinylsulfone reactive group and a monofluorotriazine reactive group under the brand name Cibacron.
