Tris(trifluoropropyl)trimethylcyclotrisiloxane. Tris(trifluoropropyl)trimethylcyclotrisiloxane (D3F) is a chemical substance. It is a derivative of hexamethylcyclotrisiloxane (D3), but also belongs to the class of per- and polyfluoroalkyl substances (PFASs).

It occurs in two diastereomeric forms:

D3F is used to produce polymethyltrifluoropropylsiloxane (PMTFPS). The starting material is dichloromethyl(3,3,3-trifluoropropyl)silane. Tetrakis(trifluoropropyl)tetramethylcyclotetrasiloxane (D4F) is produced as a reaction by-product.

It has been detected in wastewater, sewage sludge as well as in biosolid-amended soils.

Flying Tiger Line Flight 45. Flying Tiger Line Flight 45 was a regularly scheduled cargo flight by Flying Tiger Line from Los Angeles to Da Nang Air Base in South Vietnam, with intermediate stops at San Francisco, Seattle, Cold Bay, Tokyo, Naha, Hong Kong, and Cam Ranh. On July 27, 1970, the flight, a Douglas DC-8-63F, crashed on final approach as it was trying to make its 4th stopover at Naha Airport (then Naha Air Base) in Okinawa, which was under US administration at the time.

Aircraft 
The aircraft involved was a Douglas DC-8-63F registered as N785FT with serial number 46005. It was manufactured in 1968 and purchased by Flying Tiger Line on November 19. It had logged 6047.2 airframe hours and was powered by four Pratt & Whitney JT3D-7 engines, each generating about 19000 pounds of thrust.

Overview 
The aircraft involved in the incident was a Douglas DC 8-63F with the registration number N785FT and serial number 46009, and powered by four Pratt & Whitney JT3D-7 engines. The aircraft was delivered to Flying Tiger Line on November 19, 1968. At the time of the incident, the aircraft had accumulated a total of 6047.2 hours. The aircraft took off from Los Angeles International Airport at 20:53PM on July 25 and after 3 scheduled stops arrived at Haneda Airport at 22:44PM on July 26. The aircraft and crew stayed over at Tokyo for the night before taking off on 9:29AM for Naha Air Base.

The aircraft was making its final approach to Naha Air Base's Runway 18 using precision radar approach at around 11:35AM when the aircraft's rate of descent increased and subsequently crashed 2,000 feet short of the runway. All four crew members died.

Cause 
Flying Tiger Line Flight 45 flew from Tokyo to Naha using IFR, and crashed on final approach just as it had passed a low level raincloud.

The investigation by the National Transportation Safety Board concludes that the aircraft encountered a tropical storm while on approach with visibility not reaching 1 mile, only for visibility to increase by 10 to a 100 times once the clouds cleared, blinding the piloting crews and making the approach difficult.

Amit Keren. Amit Keren (Hebrew: עמית קרן) is an Israeli Professor of Physics in the Department of Physics Technion-Israel Institute of Technology. He is an experimentalist investigating mostly the properties of magnetic and superconducting material.

He worked on compounds such as spin glasses, frustrated magnets, molecular magnets, and superconductors. He uses experiential techniques such as muon, electron, and nuclear spin resonance, magnetometers, transport, neutron scattering, various kinds of x-ray scattering and photoemission. He also operates a single crystal growth lab.

Education 
Amit Keren received his B.Sc. in Physics and Mathematic in 1986 from Tel Aviv University, his doctorate in 1994 from Columbia University under the supervision of Tomo Uemura, and was a postdoctoral fellow at Orsay University Paris, under the supervisor of Henry Alloul until 1997.

Research work 
Common energy scale for magnetism and superconductivity: The Keren group demonstrated experimentally that superconductivity and magnetism in the high temperature cuprate superconductors share a common energy scale, namely, the critical temperature and the superexchange interaction strength are proportional to each other. This finding is backed by many different experiments.

Mapping exotic spin correlations in spin glasses: Keren and collaborators found experimentally that close to the spin glass transition temperature, the field-time-dependent polarization of a probing spin scales like their ratio. They interpreted this behavior using power law correlation function.

Muon relaxation in a stochastic field environment: When a spin polarized muon enters a magnetic sample, it loses its polarization. The analytical relation between the muon polarization and the stochastic properties of the field is known as the Keren function.

Stiffnessometer: When the current in a very long coil, which pierces a superconducting ring, is turned on, a persistent current is generated in the ring. The amount of current depends on the superconductor stiffness. By measuring this current via the magnetic moment of the ring the stiffness can be determined. The Keren group developed an instrument based on these principles

Advanced Qualification Program. The Advanced Qualification Program (AQP) is the alternate pilot qualification method by the Federal Aviation Administration. AQP is a voluntary program by pilots to meet up to the ‘traditional’ regulatory requirements. AQP serves as a means of compliance to qualify, train, and certify the competence of pilots flight attendants and competence of pilots, flight attendants and dispatchers.

History 
As human error had emerged as the primary cause of US air carrier accidents in the 1980s, the FAA and carriers agreed more flexible training regulations would reduce the accidents.

Methodology 
Operational data analysis is used to assess the participants competency in the objective requirements for all aspects of training. Pilots are evaluated based on their ability to show proficiency in scenarios that test both technical, cognitive and crew resource management skills together.

Due to the data driven nature of the program, air careers under the AQP need to design data collection strategies to measure cognitive and technical skills of the trained pilots.

Sustainable urban agriculture. Sustainable urban agriculture is an emerging field that involves the practice of growing fruits, vegetables, and other food crops within city limits, using methods that are environmentally friendly and socially responsible. The concept of SUA is rooted in the belief that cities can and should produce a significant portion of their own food to reduce dependence on industrial agriculture and its associated negative environmental impacts, such as pesticide use, water pollution, and fossil fuel consumption.

Methods 
There are several different approaches to SUA, including:

 Community gardens: plots of land that are collectively managed by a group of individuals, often located in underutilized urban spaces such as vacant lots or parks.
 Rooftop gardens and green roofs: cultivation of plants on top of buildings.
 Urban farms: larger-scale agricultural production within city limits, often using innovative technologies such as hydroponics and aquaponics.
 Vertical farms: method of growing crops indoors in stacked layers, using artificial lighting and controlled climate.

Benefits 
Sustainable urban agriculture (SUA) offers several benefits, including:

 Reducing dependence on industrial agriculture and its associated negative environmental impacts
 Improving air quality, providing educational opportunities and promoting community development
 Year-round production, regardless of weather conditions
 Reduced water usage and the need for pesticides.

Criticism 
SUA has received concerns about its feasibility, scalability, and sustainability. Some of the criticisms of SUA include:

Feasibility and scalability 
Critics argue that SUA may not be able to meet the food needs of a large urban population, as the amount of land available for farming within cities is limited. Additionally, some critics argue that the costs of implementing and maintaining SUA may be too high for many cities to bear.

Sustainability 
Critics argue that SUA is not truly sustainable, as it requires the use of energy, water, and other resources, which may not be available in sufficient quantities in urban areas. Additionally, some critics argue that the use of pesticides and other chemicals may be necessary to maintain the productivity of urban farms, which could have a negative impact on the environment.

Economic viability 
Critics argue that SUA may not be economically viable, as the costs of setting up and maintaining an urban farm may be high and the yields may not be sufficient to make it a profitable enterprise.

Von Braun Interceptor. The von Braun Interceptor was a VTOL rocket-powered interceptor designed by Wernher von Braun. This aircraft would have used the technology Von Braun had developed for the V-2 rocket during World War II.  Von Braun put forward the proposal to Reichsluftfahrtministerium, on July 6, 1939, but project was ultimately not built.

Background
In 1936, von Braun worked to convert some propeller aircraft to be powered by more powerful rocket engines.  In 1937, the He 112 V3 and He 112 V5 were fitted with rocket engines, but the V3 was destroyed when it suffered an engine explosion during a test.  The He 112 V5, piloted by test pilot Erich Warsitz, was flown to 800 meters (2,625 feet), where Warsitz fired the rocket motor.  The He 112 V5 was the first aircraft to be powered by a liquid-fueled rocket engine, paving the way for more rocket-powered planes built by Germany during World War II.

Design

The von Braun Interceptor featured a conventional design with straight, tapered wings.  Two fuel tanks, one with alcohol and the other with liquid-oxygen, where located behind the pilot, while the rocket engine was located in the tail.  The aircraft was to have an armored, pressurized cockpit for high-altitude flight.  The von Braun Interceptor would take off vertically like the V-2 rocket.  The plane would be stored, fueled and readied for takeoff in a hangar with its nose pointed to the sky, and thus would not need an airfield.  The aircraft would slide out on two rails to take off or to be loaded onto a launch vehicle.  As the aircraft climbed to altitude, the vanes in the rocket exhaust would be used for control.  As the aircraft moved from vertical to horizontal flight the pilot would move to conventional controls and an auxiliary combustion chamber.  After the attack, the aircraft would glide back to the base.  The 1936 design was very much ahead of its time, as the V-2 rocket would not make its first flight until 1944.  This is one of the reasons that the project was not adopted in 1936.  A second design for the von Braun Interceptor had wings with rounded ends and used Visol and SV-Stoff for fuel.  With the new fuel, the von Braun Interceptor would be launched from a truck and was intended to be easier to fuel.  The von Braun Interceptor was to be armed with four guns; two per wing.

The von Braun Interceptor plans were given to the Fieseler Company, which developed it into the Fi 166 in 1941.  The von Braun Interceptor also inspired the Bachem Ba 349 Natter.

Spacewell. Spacewell is a software and technology company working with the real estate and facility management industries. The company is headquartered in Antwerp, Belgium, with offices in Europe and APAC. Spacewell is owned by the Nemetschek Group, a multinational company.

History 
The company was founded as a consultancy firm called MCS in 1989 in Antwerp by Marcel Eeckhout. It started with developing a product in the area of CAD drawings for built assets. The company's team developed a technology to turn these drawings into data, so that non-specialists were able to work with them. Over time a range of real estate, facility management and workplace software were added, running on a central database, resulting in an Integrated Workplace Management System (IWMS). In 2012, MCS was taken over in a leveraged management buy-in by Koen Matthijs and Steven Lambert.

In April 2016, MCS received €6 million financing from investors PE Group and Jadeberg Partners for integration of IoT into facility management. On August 28, 2018, MCS was acquired (100% of its shares) by the Frankfurt Stock Exchange listed Nemetschek Group, a software provider in the architecture, engineering and construction industries. Six months after the purchase, in February 2019, MCS was rebranded to Spacewell.

In January 2019, Spacewell acquired Dutch SaaS company Axxerion and in December 2020, Spain-based Dexma.

Software 
Spacewell cloud software connects with the IoT (Internet of Things) to focus on the efficient usage of buildings, e.g. optimizing occupancy, air quality, space and energy management, as well as providing real-time analytics about the buildings.

HNLMS Zeefakkel (A903). HNLMS Zeefakkel was a hydrographic survey vessel built in the Netherlands for the Royal Netherlands Navy. She was specially designed to perform surveys in coastal areas and did this between 1951 and 1972. Later she was turned into a training vessel.

Design and construction
Zeefakkel was built at the shipyard of J. & K. Smit in Kinderdijk. The ship was laid down on 28 November 1949, launched on 21 September 1950 and commissioned into the Royal Netherlands Navy (RNN) on 22 May 1951. The survey vessel got assigned the pennant number A903.

The ship was equipped with two 8 cylinder four-stroke Smit-Man diesel engines that could produce 320 horsepower each, for a total of 640 hp. This allowed Zeefakkel to reach a maximum speed of 12 knots.

For performing surveys the ship was equipped with several systems: it had a echo sounder, radar, ASDIC, Decca and gyrocompass.

Service history
Zeefakkel performed hydrographic surveys till the end of 1972. The ship was afterwards replaced by one of the hydrographic survey vessels of the Buyskes-class. Nonetheless, Zeefakkel did stay in service of the RNN as training vessel.

She was re-engined in 1980. 

Zeefakkel was still in service circa 1999-2000, when Jane's Fighting Ships 1999-2000 wrote that she was being used as a local training ship at Den Helder. She was to be replaced by another ship possibly to be launched in late 1999. Jane's no longer listed the ship as having any armament.

After the new vessel was placed in service Zeefakkel was laid up in reserve until January 2000, when she was handed over to the Dutch Sea Cadet Corps as a training ship (:nl:Zeekadetkorps). By 2023 she was still in service in that function.

Scandium perrhenate. Scandium perrhenate is an inorganic compound, with the chemical formula Sc(ReO4)3. Its thermal stability is lower than that of the corresponding compounds of the yttrium and lanthanum perrhenates.

Preparation and properties 

Scandium perrhenate can be obtained by reacting perrhenic acid with scandium oxide. From the solution, the trihydrate of scandium perrhenate can be precipitated, which loses water at 50 °C to obtain Sc(ReO4)3·H2O, and obtains the anhydrous form at 140 °C. Scandium oxide and rhenium(VII) oxide are formed at 550 °C.

Scandium perrhenate trihydrate is a crystal in the triclinic crystal system, with space group P, a=7.333, b=7.985, c=20.825 Å; α=93.35, β=92.20, γ=97.42°.

Scandium perrhenate can crystallize with ammonium perrhenate in water to form NH4Sc(ReO4)4·4H2O.
