Per Gillbrand. Per Sune Evaldsson Gillbrand (23 March 1934 – 30 November 2016) was a Swedish automobile engineer. Born in Tidaholm, Gillbrand is best known for his contribution to the development of several engines for Saab, and in particular their turbocharged engines.

Career
After graduating from the Tekniska gymnasiet i Göteborg (Technical High School of Gothenburg), Gillbrand started working for Volvo in 1956, initially as a test engineer in Skövde and later as an engine development engineer in Gothenburg.

Saab, Sweden's other major car manufacturer, was in need of 4-stroke engine expertise as they phased out the 2-stroke engines used in their earliest models. They recruited Gillbrand, along with Olle Granlund, another colleague from Volvo, in 1964.

Gillbrand's first assignment for Saab was the final test of the Ford Taunus V4 engine in the Saab 96. He was then involved in adapting the Triumph slant-four engine for the Saab 99. This engine was later replaced by the Saab B engine, an updated version of the Triumph unit manufactured at Saab-Scania in Södertälje.

In 1970 Gillbrand became manager of Saab-Scania's engine laboratory in Södertälje, where he was in charge when Saab became the first car manufacturer to use small turbochargers in gasoline engines, along with technologies such as the wastegate found in most modern turbocharged engines today. For his work on forced induction engines, Gillbrand earned the nickname Turbopelle (Turbo-Geek).

Inventions
Gillbrand is the inventor of the Automatic Performance Control system. 

Another of Gillbrand's inventions is the Electronically Controlled Variable Compression engine that he built in the late 1990s. Later renamed the Saab Variable Compression engine (SVC), it was presented at the 2000 Geneva Motor Show. General Motors (GM), Saab's owner at the time, did not approve further development of the SVC engine. This technology is today in development by car manufacturers such as Nissan, Infiniti and Porsche more than 20 years after Gillbrand originated the idea.

Honours
Gillbrand was awarded a Gold Medal from the Swedish Royal Academy of Sciences for his research work in 1988, and in 1992 he received the title of Honorary Doctor of Technology from Chalmers University in Gothenburg.

In 2006 he was made an honorary member of the Svenska Volvo P1800-klubben (Volvo P1800 Club of Sweden) for his contributions to development of the Volvo B18 engine.

In 2023, Gillbrand was posthumously awarded the international motororganization Fédération Internationale des Véhicules Anciens (FIVA) Heritage Hall of Fame. The motivation for the awarded was his pioneering contribution to the world of automobiles, especially the work at Saab with the turbocharged engines.

P120C. The P120C is a solid-fuel rocket motor designed for use as the first stage of the Vega-C and as the boosters of the Ariane 6 launch vehicles. The solid rocket motors were developed by Europropulsion, a joint venture of Avio and ArianeGroup, for the European Space Agency. The "C" in the name signifies its "Common" use across these vehicles.

As of July 2022, it holds the title of the world's largest and most-powerful single-piece solid-fuel rocket motor, surpassing its predecessor, the P80.

Development and Testing 
Initially, production of the P120C was planned to be divided between Avio's main facility in Italy and MT Aerospace in Germany. However, in 2018, ESA decided to consolidate production entirely in Italy, with MT Aerospace focusing on Ariane 6's turbopumps.

The first successful test firing occurred at the Guiana Space Centre in July 2018, lasting 140 seconds and simulating a complete first-stage burn. Subsequent tests in 2019 and 2020 confirmed the motor's flight readiness for both launcher configurations.

Design and Performance 
The P120C builds upon the P80's design, utilizing a carbon fibre casing constructed via filament winding and fabric deposition techniques. It houses a  of HTPB 1912 propellant, a blend of 19% aluminium powder, 69% ammonium perchlorate with 12% of hydroxyl terminated polybutadiene binder. The motor's  thick walls require a  of carbon fiber, wound over 33 days in a climate-controlled environment. When operational, the P120C generates an average thrust of .

P160C 

In 2022, development began on the P120C+ variant, which would evolve into the P160C. This extended version adds  to the motor's length and an additional  of propellant. This upgrade translates to a roughly  improvement in lift performance on the Ariane 64 with four boosters. Notably, 16 of the planned 18 Kuiper launches by Ariane 6 will utilize this enhanced booster.

Curtiss O. The Curtiss O was a  water-cooled V-8 aero-engine, which was the basis of the commercially successful Curtiss OX series of engines.

Design and development
In 1909 Glenn Curtiss won the inaugural Gordon Bennett Trophy flying a Curtiss racing biplane powered by a V8 engine featuring a cross-flow OHV configuration (two overhead valves, one rocker, one push-pull rod per cylinder).  At that time most of Curtiss’s competitors were using less-efficient suction intake valves.    

Curtiss continued the development of their V8 OHV engines with demand for higher power outputs being driven by the US Navy’s requirement for seaplanes.  By 1912 Curtiss V8’s were developing 75 hp at 1,100 rpm and were known as the Model O.    
  
The Model O was further developed to achieve 90 hp at 1,200 rpm at which time it was designated as the Curtiss Model OX.  Curtiss OX production started in 1913 and it became the first mass produced American aero engine series. The most successful engine in the series was the Curtiss OX-5 which powered many early American aircraft including the Curtiss Jenny, the standard trainer used by American and Canadian forces during World War One.

Annie 30. The Annie 30, often just called Annie, is an American sailboat that was designed by Chuck Paine as an offshore cruiser and first built in 1980.

The Annie design was later developed into the Annie 2 by Paine and offered as plans for custom building or amateur construction.

Production
The design was built by Morris Yachts in Bass Harbor, Maine, United States. The company built 16 examples of the design, starting in 1980, but it is now out of production.

Design
The Annie is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a spooned raked stem, a sloped transom, a transom-hung and keel-mounted rudder controlled by a tiller and a fixed long keel, with the forefoot cutaway. It displaces .

The boat has a draft of  with the standard keel fitted.

The boat is fitted with a Westerbeke two-cylinder diesel engine for docking and maneuvering. The fuel tank holds  and the fresh water tank has a capacity of .

The cabin has two design interior versions, both using teak trim. One has a forward head, just aft of the "V"-berth, while the other has an aft head, in place of the chart table and a dresser in the forward cabin. The forward cabin has a privacy curtain. The galley is located aft, on the starboard side, just ahead of the companionway stairs and has an optional two-burner stove. A shower is also optional and uses freshwater engine cooling to heat the water. Ventilation is via nine opening ports.

The genoa has tracks and the mainsheet traveler is mounted aft of the cockpit.

Operational history
In a review Richard Sherwood described the design, "Annie is a heavy-displacement boat, but she has a very tall rig and much greater sail area in the jib than older boats. In addition, freeboard is low, the bow is sharp, and the keel is quite narrow. The forefoot is cut away. With the long keel and the
heavy displacement, Annie should track well. The tall rig will assist in light air."

Temper (pottery). A temper is a non-plastic material added to clay to prevent shrinkage and cracking during drying and firing of vessels made from the clay. Tempers may include:

Bone;
Chaff;
Charcoal;
Ground schist;
Wood ash;
Grit;
Sand or crushed sandstone;
Crushed limestone;
Crushed igneous rocks, such as volcanic rock, feldspar, or mica;
Grog;
Plant fiber;
Horse manure (dried and sifted);
Crushed mollusc shells (including fossilized) (see Shell tempering in the Mississippian culture); and
Freshwater sponge spicules.

Some clays used to make pottery do not require the addition of tempers. Pure kaolin clay does not require tempering. Some clays are self-tempered, that is, naturally contain enough mica, sand, or sponge spicules that they do not require additional tempering.

Leigh 30. The Leigh 30 is an American sailboat that was designed by Chuck Paine as a cruiser and first built in 1979.

The Leigh 30 design is also known as the Morris 30 and is similar to the Victoria 30, both Paine designs. The Victoria 30 was built by Victoria Yachts in England.

Production
The design was built by Morris Yachts in Bass Harbor, Maine, United States. The company built 19 examples of the design, starting in 1979, but it is now out of production.

Design
The Leigh 30 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a cutter rig, a raked stem, a canoe transom, a keel-mounted  rudder controlled by a tiller and a fixed long keel with the forefoot cutaway. A wheel was optional. It displaces  and carries  of lead ballast.

The boat has a draft of  with the standard keel fitted.

The boat is fitted with a Westerbeke diesel engine of  for docking and maneuvering. The fuel tank holds  and the fresh water tank has a capacity of .

The boats were built with a variety of lower deck layouts, but typical is a galley on the port side with a two-burner kerosene stove, top-loading ice box and a sink with manual water pump. The head is located just aft of the bow "V"-berth, with a hanging locker opposite. There is additional sleeping accommodation in the main cabin, with a starboard pilot berth, a settee and very small port side berth. The wood used in the interior is pine and mahogany, with additional painted wood. Teak is employed above decks.

Ventilation is provided by nine bronze ports that open, plus two hatches, one over the main cabin and the other in the bow.

The cockpit has two main winches, plus a halyard winch and additional sheeting winch on the coach house roof. There are inboard genoa tracks and a bow roller for a CQR anchor on the bow.

The design has a PHRF racing average handicap of 192 and a hull speed of .

Operational history
In a review Richard Sherwood wrote, "the Leigh is moderate displacement, but the ballast/displacement ratio is 48 percent and she is stiff. The high freeboard is extended by bulwarks, making for a dry boat. The keel is moderately long, the forefoot cut away, and the sail plan balanced, so she should steer easily."

Matambo–Phombeya High Voltage Power Line. The Matambo–Phombeya High Voltage Power Line is a high voltage electricity power line under construction, connecting the high voltage substation at Matambo, Tete Province, Mozambique to another high voltage substation at Phombeya, Balaka District, Malawi.

Location 
The power line starts at Matambo, in Tete Province Mozambique, at a 400kV substation there. The power line would travel in a general north-eastern direction to the Mozambique/Malawi border, approximately  away. From there, the power line would continue into Malawi for another , to end at Phombeya, Balaka District, Malawi, for a total length of .

Overview 
The construction of this power line has been on the books, as far back as 2007. The World Bank initially approved a $93 million line of credit for this project, but cancelled it in 2010. The main objective of the electricity transmission project is to connect the electricity grids of Malawi and Mozambique. This will allow Malawi to purchase 50 megawatts of power from the Cahora Bassa Hydroelectric Power Station in Mozambique. Also, through the interconnections of the Southern African Power Pool (SAPP), Malawi will be able to import a further 150 megawatts from South Africa through the same power line.

Construction in Mozambique 
The length of the power line in Mozambique is approximately . The entire project in both countries is valued at US$154 million, borrowed from the World Bank, KfW and the European Investment Bank.

The engineering, procurement and construction (EPC) contract was awarded to L&T Infrastructure Development Projects Limited (Lasern & Toubro), an Indian company. L&T will lay the line from the Matambo electricity substation to the community of  Zobue at the international border with Malawi, a distance of about . That line will cost over US$35 million. The new 400kV substation at Matambo will be constructed by a consortium comprising Sinohydro of China and Cepco1 of Malaysia, at a budgeted cost of US$21 million.

Construction in Malawi
Work in Malawi involves the construction of  of a double-circuit 400kV transmission line and expansion of the electric substation at Phombeya. Each country is responsible for the transmission infrastructure within its territory. Completion of this energy infrastructure is expected in 2023.

In 2019 the World Bank lent US$15 million to the government of Malawi towards the construction of this line, along with a new 220kV substation in Phombeya, Malawi.
