Jnanendra Das Gupta. Jnanendra Chandra Das Gupta (German form: Inanendra) (1888 – ?) was an Indian-born chemist who developed a thermosetting plastic called Indolack while working in the Swedish company Perstorp. This led to the development of the first plastic called "isolit" used in Sweden. 

Das Gupta was born in India. He studied pharmaceutical chemistry under Fritz Ullmann (1875-1939) at the Technische Universität Berlin and received a doctorate for his thesis titled "Studien über 2-Chloranthrachinon-3-carbonsäure". His study in Germany was sponsored in 1911 by the National Council of Education Bengal and the Indian Association (through donations from Taraknath Palit) for the Cultivation of Science. He worked for a while as a chemist at Hoffmann La Roche in Basel and in 1914, he was among the earliest members of the German Friends of India or Berlin Committee, a revolutionary group begun by Virendranath "Chatto" Chattopadhyaya and supported by the German Foreign Office where Das Gupta had a friend in the Sinologist Herbert Mueller (1885-1966) (who allegedly later worked for ComIntern). Gupta later worked for the Indian National Army. Sometime later he moved from Switzerland and began to work in Sweden at Skånska Ättikfabriken AB (which later became Perstorp AB) founded by Wilhelm Wendt in Skåne 1881. In 1918 he developed Indolack based on the formula for bakelite, which he knew about, using formalin and cresol which led to the development of the first thermosetting plastic "Isolit" in Sweden. Indolack was a substitute for shellac and Isolit for solid thermoset plastic products. Das Gupta left Sweden in 1919, having been denied citizenship in the country.

Rob Marshall (motorsport). Rob Marshall (born 14 April 1968) is a British Formula One engineer for McLaren, being their Chief Designer leading their technical team after initially being hired as the Technical Director for Engineering and Design. He previously had a leading role in the Red Bull Racing team from 2006-2024.

Career

Marshall studied mechanical engineering at Cardiff University. After his study, he went to work at the design department of Rolls-Royce.

He switched to Benetton Formula as a race engineer in . He continued working for Benetton until the take over by Renault F1 team. Through a duration in which the team was taken over by Renault (2000–2002), Marshall worked his way through the ranks to eventually become Head of Mechanical Design and in 2005, his work, particularly the development of his innovative mass damper system, helped the team to its first Drivers' and Constructors’ Championship titles.

For the 2006 season, Marshall moved to the new Red Bull Racing team, where he worked with Adrian Newey in the role of Chief Designer. Here he had a key role in the cars that won 4 world titles between  and  with Sebastian Vettel. The introduction of hybrid engines to F1 led to a less successful spell, but with Marshall at the helm of the Red Bull's engineering department the podiums and victories have continued to flow. In 2016 Marshall was promoted to the position of chief engineering officer.

On 30 May 2023, it was announced that after a 17-year tenure with Red Bull Racing, Marshall would be leaving the team and joining McLaren as the Technical Director responsible for Engineering and Design, beginning in January 2024 after a period of gardening leave. However, after just three months this role was changed to that of Chief Designer as part of a technical restructuring at McLaren which involved David Sanchez, Technical Director for Car Concept and Performance, leaving the team.

OH-LCH. OH-LCH ("Hotel") is the only airworthy Douglas DC-3 airplane in Finland.

The history of OH-LCH
The aircraft was built in the Douglas Aircraft Company factory in Santa Monica, California and was completed on Christmas Eve 1942. It had been ordered by Pan American Airways, and it had been intended for their routes in Latin America. However, because of the war, the aircraft was handed over to the United States Armed Forces on 27 December 1942, and from the spring of 1943 to the fall of that year it served in the Northern Atlantic branch of the Transport Wing, probably at Presque Isle, Maine. Late in the fall of 1944, the aircraft was transferred to the Eighth Air Force in Europe, and after the war it was moved to the Oberpfaffenhofen center in Germany.

In 1948 the State of Finland purchased the aircraft for use by Aero. Its first scheduled passenger flight took place on 21 July 1948, on the Malmi–Vaasa–Tampere–Malmi route. During the following winter the aircraft was furnished for passenger use. It flew until December 1960, when it had flown 22 137 hours. It was then used for spare parts, but was reassembled and fitted with a freight door since Aero needed freight aircraft. It retained its previous registration, and was put back to service after Midsummer 1963. Aero operated the aircraft until 1 April 1967, when it flew Aero’s last DC-3 scheduled passenger flight.

In 1970 the aircraft, along with the other DC-3s owned by Finnair, was sold to the Finnish Air Force, and was given the registration DO-11. In 1985, the Air Force retired its DC-3s. and OH-LCH, along with OH-LCD, were sold to Airveteran Oy. The latter aircraft is now at the Finnish Aviation Museum.

OH-LCH today
The aircraft was previously based at Malmi Airport, but since its closure in 2021, OH-LCH has been based at Helsinki Airport. One has to be a member of the Finnish DC Association to be able to fly on the aircraft. The winter months are spent in a hangar at Vaasa Airport.

Hobie 14. The Hobie 14 is an American catamaran sailing dinghy that was designed by Hobie Alter and first built in 1967.

The design was developed into the Hobie 16 in 1971.

Production
The Hobie 14 was the initial design produced by Hobie Cat and led to a large family of similar boats that have been produced in numbers exceeding 200,000.

The design was built by Hobie Cat in the United States from 1967 until 2004 and in Europe until the late 2000s, but it is now out of production.

Design
The Hobie 14 is a recreational sailboat, built predominantly of fiberglass over a foam core. In its base model it has a fully battened catboat rig with a rotating mast and aluminum spars. A jib can be added to make it a fractional sloop rig and a trapeze is optional. The asymmetrical hulls have spooned raked stems, vertical transoms and dual transom-hung rudders controlled by a tiller. The design has an elevated trampoline for the crew. The boat has no keels, relying on the curved shape of the hulls below the waterline to prevent leeway when sailing to windward. The design displaces .

The boat has a draft of  and was designed to be sailed from a  beach. It can be transported on a trailer.

The design has a Portsmouth Yardstick racing average handicap of 86.4 and is raced with a crew of one or two sailors.

Variants
Hobie 14
Model with a single sail catboat rig.
Hobie 14 Turbo
Model with a mainsail and jib, fractional sloop rig. A trapeze is optional

Operational history
The Hobie 14 is a World Sailing competition class.

In a 1994 review Richard Sherwood wrote, "The Hobie 16 and 18 ... are faster and perhaps more popular, but the Hobie 14 was the first ... This very fast boat has been clocked at over 24 mph ... Hobies are, with Sunfish, found at resorts all over the world. There are racing fleets to match. There are regional area, national, and world championships."

Seibu 401 series. The  is an electric multiple unit (EMU) train type operated by the private railway operator Seibu Railway on commuter services in the Tokyo area of Japan from 1978 to 1997.

Seibu Railway

The first 401 series train was constructed in 1968, then known as 411 series. At the time before conversion. 411 series cars had the MT15E traction motors, in later years Seibu converted all 411 series cars to Seibu 401 series. MT15E traction motors were replaced with MT46-based Hitachi resistor-controlled motors. The last remaining trains were withdrawn in 1997.

Sangi Railway

401 series train sets were transferred to Sangi Railway in 1990. Among other Seibu EMUs sent to that railway, it's the only 2-car EMU series on Sangi Railway line.

Ohmi Railway
 Ohmi 800/820 series - entered service in 1997 (820 series) and 1998 (800 series)
 Ohmi 700 series - entered service in June 1998; withdrawn in 2019.

The 800 and 820 series conversion included modifications of the trains, so that they won't make contact with the station platforms.

MACHO catalyst. In homogeneous catalysis, MACHO catalysts are metal complexes containing MACHO ligands, which are of the type HN(CH2CH2PR2)2, where R is typically phenyl or isopropyl.  Complexes with ruthenium(II) and iridium(III) have received much attention for their ability to hydrogenate polar bonds such as those in esters and even carbon dioxide.  The catalysts appear to operate via intermediates where the amine proton and the hydride ligand both interact with the substrate. The Ru-MACHO catalyst have been commercialized for the synthesis of 1,2-propanediol from bio-derived methyl lactate.

Whitewater Interactive System Development with Object Models. Wisdom (Whitewater Interactive System Development with Object Models) is a software development process and method to design software-intensive interactive systems. It is based on object modelling, and focuses human-computer interaction (HCI) in order to model the software architecture of the system i.e. it is architecture-centric. The focus on HCI while being architecture-centric places Wisdom as a pioneer method within human-centered software engineering. Wisdom was conceived by Nuno Nunes and first published in the years 1999-2000  in order to close the gaps of existing software engineering methods regarding the user interface design.

Notably, the Wisdom method identifies for each use case the tasks of the user, the interaction spaces of the user interface, and the system responsibilities that support that user activity, which are complemented with the data entities used in each case, completing a usable software architecture, an MVC model. The Wisdom model clarifies the relation between the human and the computer-based system, allows rationalization over the software artifacts that must be implemented, therefore facilitating effort affection for a software development team.

From Wisdom, other relevant contributions were derived targeting the enhancement of software development based on the Wisdom model, such as: CanonSketch, Hydra Framework Cruz's

Another relevant contribution is related to effort estimation of software development, the iUCP method, which is based in traditional UCP method leveling the estimation based on the predicted user interface design. A comparison study was carried out using both methods, revealing that there is positive effect in the usage of iUCP when compared to UCP when considering the user interface design, a recurrent situation in nowadays software systems development.

Michel Armand. Michel Armand (born 1946) is a French scientist who is best known for introducing the concept of
a rocking-chair battery in 1978. In rocking-chair battery the same type of ion is de/intercalated into both positive and negative electrode during dis/charge. As a result, solution-phase species do not appear in the reaction stoichiometry, which allows for minimizing the amount of solvent in the battery, reduces the battery weight and cost.

Michel grew up in Annecy, in the French Alps, in a family of science teachers. In 1968 he graduated from Ecole Normale Superieure, where he became interested in electrochemistry and batteries. In 1970 he started his PhD studies at Stanford University with Robert Huggins as a Fulbright Scholar. Stanley Whittingham was a postdoc in the same laboratory at Stanford. Armand felt that the Stanford laboratory was focused too much on fundamental studies, while he wanted to develop practical batteries. For this reason, he dropped out of Stanford's PhD program 18 months later and returned to France to finish his PhD at Université Joseph-Fourier in Grenoble.

While in graduate school, Armand was determined to find a practical way to intercalate lithium and potassium ions into graphite. He found, that solvent co-intercalation presented a problem with lithium ions. For this reason he decided to try a solid polymer electrolyte and obtained a patent on this idea. However, the lack of a suitable positive intercalation electrode material prevented commercialization of that invention at that time.

Lithium batteries are electrochemical devices that are widely used as power sources. The history of their development has contributions from many scientists, but in particular without the developments by Professor Michel Armand related to the electrodes and electrolytes the lithium batteries of today would not exist as the foundation for electronic devices.

He runs a research team in Spain at CIC energiGUNE and has had his work published in Nature.

Václav Aulický. Václav Aulický (born March 1, 1944 Prague, Czechoslovakia) is a Czech architect and university professor. He is a graduate of the Faculty of Civil Engineering of the Czech Technical University in Prague. His buildings have hi-tech and postmodern elements.

Biography 
Václav Aulický was born on March 1, 1944, in Prague. In 1967 he completed his studies in architecture at the Faculty of Civil Engineering of the Czech Technical University in Prague.

From 1967 to 1970, he worked at the Military Project Institute. Here, in Jiří Eisenreich's studio, he participated in the design of the Transgas building complex at Vinohradská 6 in Prague, which was built in 1972–1978. His task was, for example, the design of the cladding of the upper floors of high-rise buildings, where weather-resistant steel was used, produced since 1968 in Czechoslovakia under the product name ATMOFIX. During his time at the Military Project Institute, he also undertook several study trips. He was, for example, in Austria, the Scandinavian countries, or in Italy.

He has been working for Spojprojekt since 1974. Here he got to his own realizations. These were the Hošťálkovice Television Transmitter in Ostrava or the Telephone Exchange in Dejvice or Hradec Králové. At the end of the 1970s, he began working on the design of the Žižkov Television Tower.

He is a member of the Czech Chamber of Architects and since 1990 the Community of Architects of the Czech Republic. With his wife, architect Zdenka Aulická, he has two daughters and six grandchildren. He runs a studio at Spojprojekt, dealing mainly with telecommunications buildings and transmitters.

Since 2005 he has also been working at the Faculty of Architecture of the Czech Technical University as the head of the studio. He later habilitated there as an associate professor.
