USV RSV (Marine Tech). The RSV (Remote Survey Vehicle) is an unmanned surface vehicle developed by the founders of Marine Tech SAS since 2008.

Features 
Engineered and designed as an autonomous and robust marine surface platform, the RSV can operate several oceanographic sensors simultaneously to achieve measurements, exploration of aquatic environment and hydrographic survey.

Fitted with a high resolution infrared camera, the RSV can also be considered as an autonomous platform for surveillance and security of sensitive areas (ports protection, specific areas monitoring or observation of unsafe events for humans).

With an autonomy varying from 4h to 48h, the RSV is a size-optimized and user-friendly USV, remotely controlled or autopiloted.
Data measured are transmitted and visualized/controlled in real time by the distant operator.

The range of RSV allows operating:
 in difficult access areas (dams, rivers, shallow water, canals, etc.),
 offshore.
The RSV allows ROV deployment for subsea observation and monitoring.

RSV are manufactured and produced in France by Marine Tech SAS.

Shuttle pallet satellite. The shuttle pallet satellite was a satellite bus designed to be deployed and then retrieved for return to Earth on NASA's Space Shuttle. It carried a variety of payloads both scientific and military in nature.

It was made by Messerschmitt-Bölkow-Blohm and first flew in 1983. It was carried for the first time  during the STS-7 mission and called SPAS-01 carrying 10 payloads. It flew again on the STS-39 mission in 1991 called IBSS-SPAS (Infrared Background Signature Survey – Shuttle Pallet Satellite) for the DOD testing various ballistic missile detection sensors.

SPAS flew for the third time with the STS-51 mission in 1991 called ORFEUS-SPAS (Orbiting & Retrievable Far & Extreme UV Spectrometer – Shuttle Pallet Satellite) with ultraviolet instruments. ORFEUS-SPAS was flown again on the STS-80 mission.

SPAS was flown for the second to last time with the CRISTA-SPAS (Cryogenic Infrared Spectrometers & Telescopes for the Atmosphere – Shuttle Pallet Satellite) payload on STS-66 in 1994 mounting several infrared sensors looking at the Earths atmosphere, and that payload flew again on STS-85 in 1997.

Ledger (journal). Ledger is the first peer-reviewed academic journal dedicated to cryptocurrency and blockchain technology research.
The journal covers topics that relate to cryptocurrencies such as bitcoin.  This includes aspects of mathematics, computer science, engineering, law, economics and philosophy. 
The focus according to Wilmer is "blockchain technology research."
It is funded by Coin Center, a nonprofit. 

The journal is open access.  It is published by the University Library System of the University of Pittsburgh and is cosponsored by the University of Pittsburgh Press.

Creation 

The idea for the journal was born out of a discussion between managing editors Peter R. Rizun and Christopher E. Wilmer, on the bitcoin forum bitcointalk.org.

Wilmer envisioned ledger as a journal for "people passionate about the technology, to publish their research."
Wilmer called into question the reliability of 'white papers' that became common in the cryptocurrency boom.
According to Wilmer, the Ledger Journal receives two to four submissions a week, and many are of poor quality.
“Occasionally we get submissions with no citations."
Wilmer's vision for Ledger was to use a more a traditional peer review system.

A call for papers was issued on 15 September 2015 with the deadline set to 31 December 2015.  However, this was delayed while formalising the review process.  The inaugural issue was not published until December 2016.

Related persons and organizations 

Rizun is a physicist and entrepreneur, who lives in Vancouver, Canada.

Wilmer is an assistant professor in the Swanson School of Engineering’s Chemical & Petroleum Engineering Department.
He is the author of Bitcoin for befuddled. Wilmer first used bitcoin to purchase honey caramels from a beekeeper.

The University of Pittsburgh was featured in the documentary The Rise and Rise of Bitcoin.

SS Brazil Victory. The SS Brazil Victory, United States Maritime Commission designation VC2-S-AP3, hull number 8 (V-8), was the eighth Victory ship built during World War II. Built in 113 days under the Emergency Shipbuilding program, the ship was launched by the California Shipbuilding Company on March 30, 1944, and completed on May 26, 1944. SS Brazil Victory served in the Pacific Ocean, the Indian Ocean, and the Atlantic Ocean during World War II. She was named for the nation of Brazil, one of the Allies of World War II.

World War II
Brazil Victory was operated by  Mississippi Shipping Company under charter with the Maritime Commission and War Shipping Administration. SS Brazil Victory served as both an ammunition ship and a cargo ship during World War II. After the inauguration of the SS Brazil Victory, she was launched into the waters of the Cerritos channel, and sailed to and was crewed at San Francisco. She was then loaded with ammunition at Long Beach, California, and from there steamed to Melbourne, Australia to unload cargo destined for the Pacific War. From Australia, she steamed to Calcutta, India, where she was loaded with cocoa beans and latex rubber. She then steamed south of South Africa around the Cape of Good Hope into the Atlantic Ocean, completing her circumnavigation of the world with her arrival in Philadelphia on October 19, 1945.  She was retired in 1948 to the National Defense Reserve Fleet at Beaumont, Texas until she was put back in service in 1950.

Korean War
SS Brazil Victory, commanded by Captain Charles Brown, served as a merchant marine naval ship in the Korean War. She was one of many merchant marine ships, which transported about 75 percent of personnel and about 91.12 percent of the cargo to Korea. SS Brazil Victory made the trip between November 18, 1950, and December 23, 1952, transporting goods, mail, food and other supplies to American forces engaged against Communist forces in Korea, via Busan and other ports in South Korea.  After her service, she was kept in the National Defense Reserve Fleet at Suisun Bay until 1966.

Vietnam War and end of service
In 1966, SS Brazil Victory was once again removed from the Reserve Fleet, reactivated, and put into operation by American President Lines. She transported cargo and a small number of troops for the Vietnam War. 
In 1973, she was retired to the Reserve Fleet at Suisun Bay, and in 1993, she was scrapped in Huangpu, China.

Helium-3 nuclear magnetic resonance. Helium-3 nuclear magnetic resonance (3He-NMR) is an analytical technique used to identify helium-containing compounds. Because a helium atom, or even two helium atoms, can be encased in fullerene-like cages, the nuclear magnetic resonance spectroscopy of this element can be a sensitive probe for changes of the carbon framework around it. Using carbon-13 NMR to analyze fullerenes themselves is complicated by so many subtle differences among the carbons in anything but the simplest, highly-symmetric structures. The technique is limited by the need to use the rare helium-3 isotope: the vast majority of naturally occurring helium is helium-4, which does not have suitable magnetic properties for NMR detection.

Julius Lewkowitsch. Julius Isidor Lewkowitsch (1857–1913) was a German chemical engineer, specialising in vegetable and animal oils and fats, who settled in Victorian England. He was the author of The Chemical Technology and Analysis of Oils, Fats, and Waxes, a standard text that went through five editions in the years 1895–1921.

Life
Julius Lewkowitsch was born in Ostrowo (then in the Kingdom of Prussia) on 4 September 1857, into a Jewish family. In 1879 he obtained a doctorate from Breslau University, where he studied under Victor von Richter. After short periods as a secondary-school teacher and as a research assistant to Victor Meyer at Heidelberg University, Lewkowitsch became an industrial researcher. In 1887 he moved to England as Technical Manager to the soap manufacturers Joseph Watson & Sons in Leeds, where he developed a way of preparing glycerin from soap lye without the use of arsenic. In 1889 he became a member of the Society of Chemical Industry. In 1895 he set up in business as a consulting chemist in Manchester, moving to London in 1898. He established his own laboratory in West Hampstead.

On 5 May 1902 Lewkowitsch married Katherine Julia Morris. Their two children were Elsa Lewkowitsch and Jason Farradane. Lewkowitsch died at Chamonix on 15 September 1913.

In 1980 the Society of Chemical Industry's biennial Julius Lewkowitsch Memorial Lecture was established in his memory in accordance with a bequest by his daughter, Elsa.
