4,4′-(Hexafluoroisopropylidene)diphthalic anhydride. 4,4′-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) is an aromatic organofluorine compound and the dianhydride of 4,4′-(hexafluoroisopropylidene)bisphthalic acid (name derived from phthalic acid).

Synthesis 
The raw materials for 6FDA are hexafluoroacetone and orthoxylene. With hydrogen fluoride as a catalyst, the compounds react to 4,4′-(hexafluoroisopropylidene)bis(o-xylene). This is oxidized with potassium permanganate to 4,4′-(hexafluoroisopropylidene)bisphthalic acid. Dehydration gives the dianhydride 6FDA.

Applications 
6FDA is used as monomer for the synthesis of fluorinated polyimides. These are prepared by the polymerisation of 6FDA with an aromatic diamine such as 3,5-diaminobenzoic acid or 4,4'-diaminodiphenyl sulfide. Such fluorinated polyimides are used in special applications, e. g. used to make gas-permeable polymer membranes, in the field of microelectronics and optics, such as optical lenses from polymers, OLEDs, or high-performance CMOS-contact image sensors (CISs).

These polyimides are typically soluble in common organic solvents, facilitating their production and processing. They have very low water absorption, which makes them particularly suitable for special optical applications.

Enchantment of the Seas. Enchantment of the Seas is a Vision-class cruise ship operated by Royal Caribbean International.

In September 2017, Enchantment of the Seas evacuated the company’s employees and their families from Miami when they had been endangered by Hurricane Irma.

Propellers

The two propellers are highly skewed fixed pitch types, manufactured in Sweden. Enchantment of the Seas and her sister ship Grandeur of the Seas were the first two major cruise ships to be equipped with a Dynamic Positioning System frequently used to maintain position while in port, particularly when tender boats are used.

Refits

In 2005, the Enchantment of the Seas was overhauled. Part of overhaul included stretching the vessel by cutting it in two amidship and adding a  long section. Enchantment of the Seas entered dry dock at Keppel Verolme shipyards in Rotterdam on 15 May 2005. The mid-body extension section was built at Aker Finnyards ahead of time, allowing the construction to be done in just over a month.

The ship resumed service on 7 July 2005, less than two months after entering dry dock. The new section added included 151 new passenger cabins.

In December 2012, Enchantment of the Seas went into drydock in Freeport, Bahamas for a further refurbishment.

Incidents
On 30 September 2009, while Enchantment of the Seas was berthed at Cozumel, Mexico, high winds pushed the cruise ship Carnival Legend against the side resulting in damage to both ships. A Royal Caribbean spokeswoman commented that the ship had minor damage to the stern and some railings. Both ships were able to depart to their next ports of call after being inspected by port authorities.

Birds-2. Birds-2 is the second iteration of a multinational program called the Joint Global Multi-Nations Birds Satellite project, or Birds project, to help countries build their first satellite. The Japanese Kyushu Institute of Technology (KIT) supported the design and fabrication of the satellites. The satellites were launched by the Falcon 9 Full Thrust rocket as a part of the SpaceX CRS-15 mission on 29 June 2018. The satellites were released from the Kibō module of the International Space Station (ISS) in August 2018.

Description 
The Kyushu Institute of Technology (KIT) in Japan supports non-spacefaring countries to build their first satellite through a program called the Joint Global Multi-Nations Birds Satellite project (Birds). Five countries had their satellites successfully launched in the Birds-1 flight: Japan, Ghana, Mongolia, Nigeria, and Bangladesh. Three countries participated in the Birds-2 program: Bhutan, the Philippines, and Malaysia. UiTMSAT-1 was Malaysia's first university-built satellite. Bhutan's satellite, BHUTAN-1, was the country's first satellite. The Philippines built their first cubesat, Maya-1. 

All three satellites were built identically, and were designed to last 6–9 months. The satellites have camera systems for imaging the Earth. Amateur radio operators can receive data transmitted from the satellites. Each country's receiving station can receive data from all three satellites with a store and forward (S&F) system.

The constellation was launched in SpaceX's Dragon spacecraft, lofted into space with their Falcon 9 rocket. It was the 15th launch of the Cargo Resupply Mission (CRS) contract to the International Space Station (ISS). Dragon was captured by Canadarm2 and docked with the space station on 2 July 2018. The satellites were released from the Kibō module of the International Space Station in August 2018.

TSMV Brading. TSMV Brading was a passenger ferry that operated between Portsmouth and the Isle of Wight between 1948 and 1986.

Background and construction

Following the Second World War, Southern Railway, which operated passenger and vehicle ferry services to the Isle of Wight, decided to supplement and replace the existing coal burning paddle steamers that operated on the Portsmouth to Ryde route with modern twin screw diesel powered vessels.

Initial plans, incorrectly based on a predicted downward trend in passenger numbers, were to order the construction of two such vessels. These were to be the identical ships  and Brading built by William Denny and Brothers in Dumbarton on Clydeside. They were launched on 11 March 1948 and went into service with British Railways, Brading being the second to enter service, on 2 December 1948. One of the existing paddle steamers, Merstone, was replaced (two having been sunk during World War II) and four were retained initially. The two ships were the first on the route to be fitted with radar which quickly proved itself in foggy conditions that had previously left the Isle of Wight cut off from the mainland.

Increasing numbers of passengers quickly led to the order for a third sister ship, , in 1951. She entered service as a one-class ship and her two sisters became one-class at the same time. The ships all received a major overhaul in 1967 with an extra passenger deck, as a continuation of the bridge deck, and improved seating and catering facilities.

Brading and Southsea outlasted their newer sister on the Portsmouth to Ryde run, being replaced in 1986 by new catamaran-type ferries,  and .

She was scrapped at Pounds Scrapyard in Portsmouth in 1994.

Incidents
On 13 May 1960 a navy liberty boat, D11, was crossing Portsmouth harbour from Gosport to HMS Vernon with civilian workers on the way home. In attempting to avoid a yacht entering harbour it was run down by Brading on its way to Ryde. Four people from the boat were killed.

Couzinet 30. The Couzinet 30 was a light transport aircraft / mailplane designed and built in France in 1930 at Société des Avions René Couzinet.

Design and development
Following closely the design characteristics of the Couzinet Arc en Ciel and other Couzinet tri-motor transport aircraft, the Couzinet 30 was a low-wing cantilever monoplane with fixed spatted undercarriage, three engines mounted on the fuselage nose and in wing nacelles, as well as the characteristic up-swept fuselage, common to most of Couzinet's designs. Intended primarily as a mailplane the Couzinet 30 could also be fitted with three or four passenger seats in the cabin.

Built of wood, with metal fittings the Couzinet 30 had a fixed tail-wheel undercarriage which could be fitted with spats throughout. Control was by conventional controls with ailerons, elevator and rudder. The birch ply skinned ailerons were in two parts, with one connected to the pilots controls and the other connected by an articulated joint, to prevent jamming in the event of wing flexure.

Power was supplied by three  Salmson 9AD radial engines in the nose of the fuselage and nacelles on each wing. Production aircraft were intended to have retractable main undercarriage and  Walter NZ-85 radial engines, for an expected gain of  in maximum speed and  in service ceiling.

Despite good performance and flying characteristics the Couzinet 30 was not produced in quantity and the sole prototype became the personal transport of René Couzinet.

Astoria Borealis. The Astoria Borealis was an industrial accident that occurred at a Con Edison substation in Astoria, Queens, New York City, on December 27, 2018. During the incident, a 138,000 volt coupling capacitor potential device failed, resulting in an arc flash, which in turn burned aluminum, lighting up the sky with a blue-green spectacle visible for miles around and as far as New Jersey. It received the humorous name "Astoria Borealis" due to its resemblance to the northern lights. The event was covered extensively on social media, and LaGuardia Airport temporarily lost power, but there were neither deaths nor injuries. Such was the magnitude of the bizarre illumination that extraterrestrial visitation was a common supposition.

Incident 
On the night of December 27, 2018, an electrical fault in voltage-monitoring equipment triggered a fire in the Astoria East substation on 20th Avenue and 32nd Street in Queens. While only part of a single section within the substation, it caused an intense blue light that could be seen for miles and lit up the night sky bright enough to resemble daytime—clearly visible across other boroughs and as far as New Jersey. The blue color was caused by refraction off the cloud cover, despite the white color of the explosion itself. LaGuardia Airport, which suffered an outage due to the accident, was forced to temporarily close. Power was also knocked out at Rikers Island, and some subway lines were disrupted. It was dubbed "Astoria Borealis" by residents and the news media.

While the substation was equipped with systems that should have stopped the accident immediately, it took four minutes to cut the flow of electricity. Due to the "apocalyptic" appearance of the aerial lights, some believed they were caused by an alien invasion or nuclear war.

Aftermath 
On January 8, New York City Councilmember Costa Constantinides used the incident as an example of why New York should no longer rely on fossil fuels when touting a new bill studying the closure of the city's gas-fired power plants. On February 11, 2019, the City Council held a hearing on the causes of the accident. Constantinides remarked that there were both air quality and safety concerns and that he wanted "hard answers."

Kurt Leibbrand. Kurt Gustav Adolf Max Leibbrand (1914-1985) was a German civil engineer, professor, and consultant transport engineer. In July 1961, he was arrested and charged with murder for the deaths of 26 unarmed Italian volunteers who were shot during the German retreat from France in August 1944, allegedly on the regimental orders he issued. Although the court only found him culpable for manslaughter, he was not sentenced because the manslaughter verdict was time-barred. His arrest lead to his resignation as a professor of railway and transport engineering at ETH Zürich.

Professional life
 From 1937 to 1950 he was with German Railways, later Councillor.
 From 1950 to 1963 he was Professor at the ETH Zurich.
 From 1963 to 1977 he worked in infrastructure consulting engineering in Frankfurt.
 From 1977 to 1979 he was Professor at the Institute of technology, Instituto Militar de Engenharia, Rio de Janeiro.
 From 1979 to 1980 he was Consultant to the Press of the Empresa Brasileira de Transportes Urbanos (Ministry of Transport (Brazil)).
 From 1980 to 1985 he was an infrastructure consulting engineer Stuttgart.

He undertook planning and consulting work in 22 countries in Europe, Turkey, Venezuela, Chile, Spain, Portugal.

Leibbrand has been considered one of the most influential post-war German transport engineers.

Arrest for war crimes

On July 24, 1961 Leibbrand was arrested on behalf of the Stuttgart District Court at Frankfurt airport, because of a command he issued as a lieutenant in August 1944 during World War II, in Orange, Vaucluse near Avignon, which led to 28 Italian volunteers of the 6th Company of the Pioneer Regiment of the 19th Army being shot down with machine guns after having mutinied when the company withdrew. A company officer ordered the unsuspecting "Hiwis" in the middle of the night to enter a small forest meadow, where they were shot. Six of them were able to escape in the dark. According to Der Spiegel, 26 were killed and five seriously injured.

Citing a lack of evidence, the Stuttgart jury released Leibbrand on 2 October 1962 from the charge of murder. Then he returned to Zurich, but not to the chair from which he was on leave. The Federal Court of Justice in Karlsruhe overturned the verdict and dismissed the case for reassessment to the Stuttgart court. On January 10, 1966 Leibbrand stood for the second time in Stuttgart in court. Despite the charge of murder, his deed was counted as manslaughter and set the procedure for prescription.

Jasic Technology Co., Ltd.. Jasic Technology Company Ltd. () is a Chinese corporation operating out of Shenzhen, in the province of Guangdong. Its headquarters are in Pingshan New District.

The company manufactures and sells inverter welding machines, engine driven welders and other welder equipment primarily used in construction. Jasic is listed on The Shenzhen Stock Exchange.

Jasic was the center of a labor and political conflict in the city of Guangdong, referred to as the Jasic Incident.

Overview 
Jasic Technology Company was founded in 2005 in Shenzhen, Guangdong. Jasic presently operates three factories in Shenzhen: Jasic Industrial Park, Chongqing Yunda Industrial Park, and Chengdu Jasic Industrial Park.

2018 labour dispute 

The Jasic Technology Company was at the center of a widely reported controversy regarding the treatment of employees at Jasic Industrial Park in Shenzhen. Workers at the plant cited low pay, long hours, poor working conditions and, in addition, accused the management of Jasic of violating Chinese labor laws through illegal coerced overtime and excessive  company fines.

In May 2018 several employees of Jasic petitioned to form a labor union with the All-China In Federation of Trade Unions, which was rejected. The workers decided to continue to build their union independently, workers reported that union organizers were attacked and beaten so after. Tensions sparked on 27 July when twenty nine workers and supporters were arrested and allegedly beaten by Shenzhen Police.

In response to the arrests, at noon on Monday, 6 August a group of eighty demonstrators publicly protested against the detainment outside of the Yanziling police station.

"At noon on Monday, about 80 supporters staged a second rally under the scorching sun outside Yanziling police station in Shenzhen’s Pingshan district, about 50 km (31 miles) from the border with Hong Kong. More than 40 Communist Party members and retired cadres, who are part of the country’s leading Maoist internet forum, Utopia, joined the rally."

A wide range of public figures condemned Chinese suppression of labor activists including MIT professor Noam Chomsky, Chinese labor activist Li Qiang,  University of Hong Kong professor Pun Ngai, Chris Chan King-chi, Jenny Chan, Neo-Hegelian philosopher Slavoj Žižek, American socialist journal Jacobin, Amnesty International, Human Rights Watch, and Cornell University.

Warsztaty Szybowcowe Mewa. The  Warsztaty Szybowcowe Mewa was a Polish, high performance, two seat sailplane flown in 1936 and built in small numbers.

Design and development

In 1935, Szczepan Grzeszczyk and Antoni Kocjan collaborated in the design of the Mewa, an aerodynamically clean, high performance, two seat sailplane. Its first flights were made early in the following year, though it was not ready for competition until 1937.

The Mewa was a wooden aircraft with a two-part, cantilever, shoulder-mounted gull wing. Each part was built around a single spar which acted as the rear member of a torsion-resistant D-box formed with plywood surfacing around the leading edge. Behind the spar, which was assisted by an internal diagonal drag strut to the fuselage, the wing was fabric-covered. The high dihedral, inner  part of the wing was rectangular in plan but the outer wing was trapezoidal, tapering to rounded tips. The outer wings carried long, narrow-chord, differential Frise ailerons outboard with mid-chord, upper-surface air brakes inboard.

The Mewa's fuselage was an oval-section, semi-monocoque, plywood structure. The two crew sat in tandem, with dual controls, under a long, multi-part transparency. This extended rearwards over the wing, allowing the second seat to be positioned over the centre of gravity to avoid re-trimming when occupied. A broad, semi-elliptical, balanced rudder, fabric-covered except on its balance, was mounted on a small fin which was part of the fuselage structure. Close to its root, the fin carried an all-flying tail, fitted with Flettner tabs and also largely fabric-covered.

The landing gear consisted of an under-fuselage, pneumatically sprung skid, assisted by a tailskid under the rudder.

Operational history

Its first significant competition was the Fifth National Glider Contest held at Ustianowa in June-July 1937 where the prototype, flown by Mieczysław Urban, came third. In 1938 a production batch of five was built, the first flying in the spring. Four took part in the Sixth National Glider Contest, held at Inowrocław, though the best only reached ninth place. The production Mewas went to clubs, where one was for used for blind flying training as well as the usual high performance instruction. They set national duration and distance records for two seat gliders: in April 1939 J. Pietrow and W. Dziergas flew for 11 h 2 min and in May Pietrow and J. Jakubiec covered .

Mewas were also built under licence in Estonia and in Yugoslavia, where one remained in use into the 1950s.
