Tsybin Ts-25. The Tsybin Ts-25 (USAF/DoD designation: Type 25; NATO reporting name: Mist) was a military glider designed by Pavel Tsybin for use by the Soviet Air Forces as a transport aircraft. Built in significant numbers, it saw service with the Soviet Airborne Forces in the late 1940s and early 1950s.

Design and development
Designed by Pavel Tsybin to a 1944 specification, the Ts-25 was of a high-wing design, with a box-shaped fuselage featuring a hinged nose for ease of loading the aircraft's cargo. The aircraft had a fixed tricycle landing gear, with skids to aid in landing, and was of steel-tube-braced wooden construction with the nose covered in fabric. The fuselage was otherwise covered in plywood; the wing was tapered, with its spar being steel-tube strut braced. The intended load of the aircraft consisted of a jeep-type vehicle and a  anti-tank gun.

Operational history
Following flight tests that completed in 1948, the Ts-25 was accepted for production; it is regarded as the first domestically produced glider to be built in significant quantities for the Soviet Airborne Forces (VDV). It was first publicly displayed at the 1948 Tushino Air Display. Eventually up to 480 of the aircraft were built at the Chkalovsk manufacturing plant between 1948 and 1954. Some were used by the VDV in training maneuvers. One was modified with 25 passenger seats for evaluation for potential civilian use on routes including Moscow, Gorki, and Novosibirsk. Two were supplied to the Czechoslovak Air Force in 1952 and given the desigation NK-25; the Yakovlev Yak-14 was preferred by the Czechs.

In 1950 two Ts-25s, towed by Ilyushin Il-12 transports, were used to resupply Polar Station SP-2.

Variants
Ts-25 Main production version, 480 built.
Ts-25M Powered version; one built. Powered by two Shvetsov M-11FR-1 radial engines each producing .

Deucalion (supercomputer). Deucalion is a supercomputer located at the Minho Advanced Computing Center (MAAC) in Guimarães, Portugal. It was inaugurated in September 2023 and is co-funded by the EuroHPC Joint Undertaking and Portugal's Foundation for Science and Technology. It is currently the fastest supercomputer in Portugal and is ranked 257th in the TOP500 global list of supercomputers.

History 
In June 2019, the European High-Performance Computing (EuroHPC) Joint Undertaking announced the building of eight supercomputers in several sites across the European Union, with the aim of equipping the European Union with a world-class supercomputing infrastructure. The Minho region in Portugal was one of the selected sites. 

In February 2021, the contract for a new petascale supercomputer, named Deucalion, was signed by the EuroHPC Joint Undertaking, the Portuguese Foundation for Science and Technology, and Fujitsu. It was also announced that Deucalion would be installed in the Minho Advanced Computing Centre (MACC).

Deucalion was officially inaugurated on 6 September 2023. It entered the TOP500 global list of supercomputers in June 2024, ranked 219th in processing speed and 80th in energy efficiency.

Architecture 
The Deucalion supercomputer consists of two main general-purpose compute partitions based on different processor architectures (ARMv8-A and x86) and one GPU-based compute partition. Users have access to the system through a set of front-end servers. All nodes are connected to a high-performance shared storage through an InfiniBand high-speed interconnect based on Mellanox QM8790 switches, and to an Ethernet network.

Deucalion’s largest compute partition is based on the ARMv8-A architecture and consists of 1632 Fujitsu PRIMEHPC FX700 nodes equipped with Fujitsu A64FX 2.0 GHz processors. Each node offers 16 GB of in-processor High Bandwidth Memory. The partition peaks at 5 petaFLOPS of double precision performance.

The second compute partition is based on the x86 architecture and consists of 500 ATOS Bull Sequana X440 dual processor nodes equipped with AMD EPYC Rome 7742 (2.25 GHz) processors. Each node offers 256 GB of RAM. The partition peaks at 2.3 petaFLOPS of double precision performance.

The GPU-based compute partition consists of 33 ATOS Bull Sequana E410 nodes equipped with four Nvidia A100 GPUs and two AMD Epyc Rome 7742 (2.25 GHz) processors. Each node offers 80 GB of High Bandwidth Memory per GPU and 512 GB of RAM. The partition peaks at 2.7 petaFLOPS of double precision performance.

All nodes have access to a high-performance shared storage based on the DDN EXAScaler subsystem using ES400VNX controllers. The storage offers a 10.6 PB parallel filesystem and a 430 TB NVM multi-purpose high-speed layer. An additional NetApp All Flash A220 network attached storage with 70 TB is available for user homes and spooling.

Jenolite. Jenolite is a British company based in Bedfordshire, England that develops and sells rust treatment products.

History and operations 
Jenolite, founded in 1939 by John H. Lawrence, initially specialized in rust inhibitors and converters before expanding to include primers and other metal treatment products. During and after World War II, it supplied anti-corrosion products for reconditioning military vehicles, supporting both the Ministry of Supply and Ministry of Defence. By the 1950s, Jenolite had expanded abroad with manufacturing sites in the US, Australia, and Belgium, where it contributed to NATO’s equipment reconditioning efforts. In the 1960s, Jenolite was integrated into Duckham Oils Ltd., and its products became widely used for industrial corrosion protection and restoration projects, such as the SS Great Britain.

Ownership changes occurred in the 1980s, eventually leading to acquisitions by Permalite and later Armour Trust, and by 2000, the brand was under Pennzoil-Quaker State with limited attention. A new Jenolite company was established in 2013, revitalizing the brand with an e-commerce business model and expanded operations in the UK, focusing on products for industrial, automotive, and restoration applications.

1,10-Decanediol. 1,10-Decanediol is a diol with the chemical formula C10H22O2. 

It can be synthesized through the reduction of dimethyl sebacate using sodium borohydride in an ethanol medium, with cerium(III) chloride serving as the catalyst. The reaction duration is one day, resulting in a yield of 93%. The product of the reduction of diethyl dithiosebacate by tetrabutylammonium borohydride is also 1,10-decanediol. The electrochemical reduction of diethyl sebacate in liquid ammonia can yield 1,10-decanediol with an impressive efficiency of 95%.

The interaction between sebacic acid and diisopropyltitanium(III) borohydride ((iPrO)2TiBH4), which is generated through the in situ reaction of diisopropyltitanium dichloride and benzyltriethylammonium borohydride in dichloromethane, can also facilitate the synthesis of 1,10-decanediol. 

1,10-Decanediol is characterized as a white solid with limited solubility in water. It exhibits a melting point of 81.7 °C and a heat of fusion of 44.0 kJ·mol−1 (252.6 J·g−1). The molecular configuration of 1,10-decanediol is described as having a zigzag conformation. The bromination of 1,10-decanediol yields 1,10-dibromodecane, whereas the reaction with thionyl chloride results in the formation of 1,10-dichlorodecane. The reaction involving 1,10-decanediol, iodine, and ammonia results in the formation of sebaconitrile with a yield of 99%.

1,10-Decanediol, along with its isomers 1,9-decanediol and 1,2-decanediol, functions as an inhibitor of soil nitrification. This inhibition can mitigate nitrogen loss from soil and prevent the environmental issues associated with nitrification in agricultural settings. Furthermore, these diols exhibit a significant inhibitory effect on nitrite-forming microorganisms, even at low concentrations.
