Design and description
The Kaba-class destroyers were improved versions of the preceding . They displaced  at normal load and  at deep load. The ships had a length between perpendiculars of  and an overall length of , a beam of  and a draught of . The Kabas were powered by three vertical triple-expansion steam engines, each driving one shaft using steam produced by four Kampon water-tube boilers. Two boilers burned a mixture of coal and fuel oil while the other pair only used oil. The engines produced a total of  that gave the ships a maximum speed of . They carried a maximum of  of coal and  of oil which gave them a range of  at a speed of . Their crew consisted of 92 officers and ratings.

The main armament of the Kaba-class ships consisted of a single quick-firing (QF)  gun located on the bow. They were also armed with four QF  guns on single mounts. Two guns were positioned abreast the middle funnel, one gun was on the aft superstructure and the fourth gun was on the stern. The destroyers' torpedo armament consisted of two twin rotating mounts for  torpedoes located between the superstructure and the stern gun.

Construction and career 
Kaede was launched on 20 February 1915 at the Maizuru Naval Arsenal and completed on 25 March. During World War I the ship patrolled the area around Singapore. In 1917, it became part of the newly formed 2nd Special Squadron's 10th Destroyer Flotilla. The squadron sailed out of Singapore, making port calls at Colombo, Aden and Port Said, before arriving at Malta on 16 April. It was then tasked escorting Allied convoys in the Mediterranean Sea. She was stricken from the navy list in November 1931, decommissioned on 1 April 1932 and subsequently broken up.

James Charnock. James Charnock (18 March 1851 – 28 May 1899) was an English mechanical engineer who spent much of his career in the Russian Empire. His nephew Clement Charnock and great-nephew Harry Charnock later joined him in the Russian Empire.

James studied at St Johns school Dukinfield and Stalybridge Mechanical Institute, whilst also working for Edward Sidebottom and Son company. Then at the age of 16 he was recommended by Platt Brothers to De Jersey & Co. to go and work as an engineer in Imperial Russia. He first worked for Ludwig Knoop at the Kreenholm Manufacturing Company, Narva, Estonia – which at the time was part of the Russian Empire.

In 1897, James was working for the Vikula Morozov Company at their factory in Nikolskoye when there was a strike by 8,000 spinners, mostly women. Charnock became involved in the negotiations, which was taken as a sign that management was reluctant to concede a reduction in the working day to levels enjoyed by workers at the neighbouring factory run by Savva Morozov. The crowd of strikers became very angry and moved onto Charnock's house. He was away at the factory, and his wife and children had fled. The police killed one worker and wounded two others, which further enraged the crowd who then invaded the Charnock residence, setting it alight.

2-Methylpentamethylenediamine. 2-Methylpentamethylenediamine is an organic compound part of the amine family with the formula H2NCH2CH2CH2CH(CH3)CCH2NCH2. A colorless liquid, this diamine is obtained by the hydrogenation of 2-methylglutaronitrile. It is better known by the trade name "Dytek A".

Uses 
2-Methylpentamethylenediamine can serve as a curing agent for epoxy resin systems. It gives good adhesion to metals and resistance against corrosion and other chemicals. It provides toughness, low blush, uniform finish, high gloss, and improves UV stability. It reduces gel time and is compatible with epoxy resins. It is suitable for marine, industrial, and decorative coatings.

2-Methylpentamethylenediamine can also be used as a chain extender for polyurethane applications, and in particular with PUDs. Its derivatives like aspartic esters, secondary amines,  aldimines and ketoimines serve as curatives in polyurea systems. In polyamides, 2-Methylpentamethylenediamine acts as a crystallinity disruptor. This makes polymers amorphous in structure and slows down crystallization. It lowers melting point, improves surface appearance, increases abrasion resistance, and dye uptake. It also reduces water absorption,  gelling, melt and quench temperatures.

In summary, its uses are:

 Corrosion inhibitor
 Polyamide adhesive and ink resins.
 Polyamide films, plastics, and fibers
 Epoxy curing agents
 Metalworking Fluids
 Chain extenders
 Water treatment chemicals
 Isocyanates

Hazards 
2-Methylpentamethylenediamine has many uses, but is a hazardous chemical. It can cause burns, is corrosive to skin, harmful when swallowed, and it can cause pulmonary edema and acute pneumonitis when inhaled in high concentrations.

MobileCoin. MobileCoin is a peer-to-peer cryptocurrency developed by MobileCoin Inc., which was founded in 2017 by Josh Goldbard and Shane Glynn.

Technology overview 

MobileCoin claims to focus on transactional anonymity (fungibility), ease of use, transaction speed, low environmental impact and low fees. MobileCoin's mechanics build on Stellar (for consensus) and Monero (for privacy), using CryptoNote alongside zero-knowledge proofs to hide details of users' transactions.

The MobileCoin company claims the cryptocurrency can facilitate decentralized payments for everyday transactions more quickly than most other cryptocurrencies.

MobileCoin is a one dimensional cryptocurrency blockchain. Blocks use a consensus protocol originally developed for the Stellar payment network. Transactions are validated in SGX secure enclaves and are based on elliptic-curve cryptography. Transaction inputs are shown to exist in the blockchain with Merkle proofs of membership and are signed with Schnorr-style multilayered linkable ring signature, and output amounts (communicated to recipients via ECDH) are concealed with Pedersen commitments and proven in a legitimate range with non-interactive zero-knowledge proofs.

Much of MobileCoin's technology comes from previous privacy focused cryptocurrencies like Monero and has been re-written in Rust for MobileCoin.

History 
MobileCoin Inc., the entity behind MobileCoin, was founded in 2017 by Joshua Goldbard and Shane Glynn. Signal's Moxie Marlinspike assisted as an early technical advisor. The coin is intended to be an accessible form of cryptocurrency with a focus on fast transactions. In May 2018, MobileCoin secured $29.7 million in a funding round led by Binance Labs, in exchange for 37.5 million tokens. The foundation raised $11.35 million in venture funding in March 2021 and $66 million in Series B funding in August 2021. Investors include Alameda Research, Coinbase Ventures, Gaingels, and Marc Benioff.

Payment and trading 
In-app payments via Signal and Mixin Messenger support MobileCoin for peer-to-peer payments worldwide. The cryptocurrency exchange BigONE currently lists MobileCoin for trading.

Criticism 
The integration of MobileCoin wallets into the popular security focused messenger app Signal received criticism. Security expert Bruce Schneier, who previously praised the app, stated that this would bloat the app and attract unwanted attention from the financial authorities.
