Noorderzijlvest. Waterschap Noorderzijlvest (WNZV) is a Dutch regional water authority covering the provinces of Groningen, Friesland, and Drenthe. It has its seat in the city of Groningen. It is responsible for water management, water quality and sewage water treatment in its catchment area.

Like many of the present water boards in the Netherlands, WNZV was created through a series of mergers of smaller regional boards over centuries. The documented history of these smaller boards and the dike rights that preceded them goes as far back as 1408. 
 
The present WNZV was created in the year 2000 from the merger of Water Board Noorderzijlvest, Zuiveringschap Drenthe and the Service Purification Management of Groningen province.

Curti Zefhir. The Curti Zefhir is a two-seat light-single turbine-powered recreational or trainer helicopter designed and produced by Italian aircraft manufacturer Curti Aerospace.
Development was partly funded by the European Commission. It performed its maiden flight in 2017 and was commercially launched at the April 2018 AERO Friedrichshafen. Curti aim to secure type certification of the Zefhir as an ultralight aircraft.

Development

Background
The Zefhir is developed by Italian aircraft manufacturer Curti Aerospace, a subsidiary of an industrial group active for more than 60 years in the mechanical engineering sector and specialized in industrial automation, packaging machinery and certified aeronautical light alloys parts manufacturing. For over 40 years, Curti has produced subassemblies and components for aerospace and defense companies, including Italian giant Leonardo S.p.A.

Curti saw a market opportunity for a better-designed light helicopter powered by a more powerful engine. Development began in 2013 after Curti formed a partnership with Czech engine maker PBS Velká Bíteš (PBSVB) and German company Junkers Profly. The rotorcraft has been developed under the DISRUPT project for reliable and secure ultralight helicopters; it was partially funded by the European Commission to support small and medium enterprises, in addition to regional financing.

Launch and testing
In April 2018, the Zefhir was launched at the AERO Friedrichshafen tradeshow in Germany, seeking for German ultralight approval and countries recognizing this certification. By late 2018, Curti expected a 2019 service entry.

By September 2018, the whole-aircraft parachute recovery system was successfully tested, with a descent rate and ground impact within crash tests requirements. The aircraft was unmanned and remotely piloted for early tests. Its unique whole-aircraft ballistic parachute was co-developed between Curti and Junkers Profly.

Design

The Zefhir complies with EASA CS-27 requirements for larger helicopters and its critical flight elements are tested accordingly. The airframe is entirely made of lightweight composite materials, as are the rotor blades. Composites materials also permitted to optimise the aerodynamic design. Its low weight and compact size allows an ultralight certification.

To recover without autorotation, the Zefhir is fitted with a ballistic parachute safety system. It is stored in a non-rotating box above the main rotor, attached to the airframe through a fixed shaft inside the rotor mast. Other systems includes a glass cockpit.

PBSVB manufactures the Zefhir’s turboshaft, derated from  maximum continuously, and optimally controlled by FADEC. Its performance is consistent under adverse weather conditions or when flown at high altitude or high temperatures. The engine drives a two-bladed main rotor with a profile maximising efficiency while lowering noise pollution.

Sutherland's Volkswagen. Sutherland's Volkswagen, or the Utah VW Bug, is a 3D model. It is a mathematical model of a 1967 Volkswagen Beetle and one of the earliest 3D computer models, aside from Catmull's hand.

The Volkswagen model was created by students of Professor Ivan Sutherland in 1972 at the University of Utah. The students created the model by measuring a real version of the car with yardsticks. Only the car body is modeled, not the wheels or chassis. The model became slightly iconic after all the various parts, as measured by students, were pieced together, with the necessary rotations, scaling, and translations.

Toczołowski-Wulw TW-12. The Toczołowski-Wulw TW-12 was a one-off, two-seat, single-engined club trainer, though certification difficulties delayed its use until 1935 and then only as a single-seater.

Design and development

Henryk Toczołowski and Józef Wulw designed the TW-12 in 1929-30 but had to build the structure slowly in their spare time. They were both members of the P.W.S. Aero Club and eventually got permission to use the P.W.S. workshops but the TW-12 was not ready for flight until the second half of 1933. There is uncertainty about the date of the first flight, which one source gives as 29 September 1933 and another as 29 November 1933.

The TW-12 was an all-wood aircraft, with a cantilever, one piece low wing which was trapezoidal in plan. It was built around twin spars and covered in a mixture of plywood and fabric.

It was powered by a  five cylinder Armstrong-Siddeley Genet radial engine. The fuselage, with rectangular section structure and rounded decking, was plywood covered. The TW-12 had two open, tandem cockpits fitted with dual control. Its landing gear was fixed and conventional.

Early flight testing revealed some handling problems, particularly at low speeds in the landing approach. After some modifications the TW-12 went to the I.B.T.L. at Warsaw for official airworthiness tests , which led again to  concerns about the low speed handling and also about the low fuel capacity (). In the summer of 1935 the TW-12 was allowed to fly as a single-seater, with the forward cockpit covered over and with a rudder of increased area.

Operational history

On its release from the I.B.T.L., the WT-12 was scheduled to take part in the P.W.S. Club rally on 28 July 1935 at their home base at  Biała Podlaska. According to one account, Antoni Uszacki decided to take advantage of a strong tail wind to fly it from Warsaw to Lviv, some  away. Despite the limited fuel capacity (, he arrived safely though with a dry tank. The club began to use the TW-12 as a trainer but its career was soon cut short by a landing crash with Tadeusz Arcinowski at the controls.

Another account states that Uszacki flew it at the rally but only achieved last (6th) place, and that Arcinowski flew it soon afterwards from Warsaw to Lviv but crashed on landing.

Zimbabwe Airways. Zimbabwe Airways (Private) Limited (operating as Zimbabwe Airways) , was a government-owned airline in Zimbabwe.

In 2018, the government dropped the plan to launch this airline.

Overview
The national carrier, Air Zimbabwe, applied to the  State Procurement Board (SPB) in October 2016 for permission to acquire four Boeing 777-200ER aircraft formerly flown by Malaysia Airlines. Permission was duly granted in November of the same.

Negotiations were carried out in secret, so as not to jeopardize the sensitive deal. Eventually the State put together enough money to pay for two of the B777s and one Embraer E-Jet. However, by the time the planes arrived in the country, Air Zimbabwe had deteriorated to such an extent, that it could not present a "credible business plan to run the planes on a sustainable, profitable basis". The government registered Zimbabwe Airways, which developed a credible business plan. The government created "Zimbabwe Aviation Leasing Company", which owns the planes and leases them to Zimbabwe Airways. As of April 2018, Zimbabwe Airways is yet to receive an Air operator's certificate (AOC), from the Zimbabwe Civil Aviation Authority.

Ownership and management
According to Patrick Chinamasa, the Zimbabwean Finance Minister, Zimbabwe Airlines is 100 percent owned by the government of Zimbabwe and was created to facilitate the national aviation industry and to relieve the cash-strapped and financially ailing national carrier, Air Zimbabwe, with over US$300 million in debts.

Destinations
The destinations of the airline are being finalized, but are expected to include London, Johannesburg, Beijing and large metropolitan and tourist cities inside Zimbabwe.

Fleet
, the Zimbabwe Airways fleet consisted of the following aircraft:

Barcarena water contamination. Following heavy rains in February 2018, the City of Barcarena, in the Brazilian state of Pará, experienced severe flooding. The Brazilian Government determined that the flooding had compromised containment pools at the Alunorte alumina refinery, citing elevated levels of heavy metals in the surrounding waters. Norsk Hydro, the majority owner of Alunorte, denied responsibility for contamination outside of its facility. In 2021, residents of the state of Pará filed a lawsuit against Norsk Hydro citing environmental impacts by its refinery operations.

Background 

Between February 16–18, 2018, the city of Barcarena, in the Brazilian state of Pará, was flooded by heavy rainfall. The flooded areas included the containment basins of Norsk Hydro’s Alunorte alumina refinery. Following the floods, the Brazilian Ministry of Health reported that Alunorte’s wastewater pools had overflowed, evidenced by elevated levels of lead, aluminum, and other substances in the surrounding waters. A report by the Evandro Chagas Institute, an organization affiliated with the Brazilian Health Ministry, determined that the levels of aluminum in the surrounding rivers were 25 times above the permitted limits.

Government investigators further discovered the existence of two “clandestine” discharge pipes at the Alunorte facility. Norsk Hydro later acknowledged the existence of the pipes, admitting that they could have leaked rainwater during the 2018 floods.

Subsequently, Norsk Hydro acknowledged there was an unlicensed discharge of rainwater during the February floods at the Alunorte facility. However, the company denied responsibility for any contamination to the local environment. Norsk Hydro claimed that the Alunorte refinery was operating normally during the 2018 floods, and that company investigators found no evidence of a spill into the outside environment.

Legal Actions 
At the end of February 2018, the Pará Court of Justice ordered the Alunorte facility to reduce production by 50% and embargoed the use of one of the refinery’s tailings basins, pending further investigation. In November 2018, a federal court upheld the decision of the Pará Court of Justice, affirming the order to limit the refinery’s capacity to 50%. On May 20, 2019, the production embargo on the Alunorte refinery was lifted by a federal court in Brazil, allowing the refinery to return to normal production.

On February 5, 2021, a class action lawsuit was filed in the Netherlands against Norsk Hydro. The lawsuit represents approximately 40,000 claimants who live in the state of Pará. The suit alleges that Norsk Hydro’s operations are responsible for toxic contamination of the Murucupi River (which bisects the city of Barcarena), and for pollution in the communities near the company’s facilities. The lawsuit cites the 2018 spill at Alunorte.
