Seafarer 23. The Seafarer 23 is an American trailerable sailboat that was designed by McCurdy & Rhodes as a cruiser and first built in 1976.

The Seafarer 23 is often confused with the 1978 Seafarer 23 Challenger and the 1963 Seafarer 23 Kestrel.

Production
The design was built by Seafarer Yachts in Huntington, New York, United States, starting in 1976, but it is now out of production.

Design
The Seafarer 23 is a recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a spooned raked stem, a slightly reverse transom, a skeg-mounted rudder controlled by a tiller and a fixed fin keel. It displaces  and carries  of ballast.

The boat has a draft of  with the standard keel and  with the optional shoal draft keel.

The boat is normally fitted with a small  outboard motor for docking and maneuvering.

The design has sleeping accommodation for four people, with a double "V"-berth in the bow cabin and two straight settees in the main cabin around a fold-down table, that combine to make a double berth. The galley is located on the starboard side at the companionway ladder. The galley is equipped with a two-burner stove and a sink. There are two locations for the head. In layout "A" it is under the cabin "V"-berth; in layout "B" it is aft of the bow cabin on the port side and is enclosed, but reduces the main cabin space. Cabin headroom is  and the fresh water tank has a capacity of .

The design has a PHRF racing average handicap of 261 and a hull speed of .

Operational history
In a 2010 review Steve Henkel wrote, "the Seafarer 23 ... has two underbody options: a 2' 4” shoal keel, or a 3' 3" 'high performance' keel ... In addition, the ... boat has a choice of two layouts ... One, Layout A, is a conventional arrangement for this size boat, with the head in the forward compartment, sandwiched between the two sides of the V-berth. If you have four people sleeping aboard, the two forward passengers will not appreciate the close proximity of any wee-hours visitors to the head from aft. The other choice, Layout B, avoids that problem, but shrinks the elbow room in the main cabin. Best features: Except for the extra-high cockpit coaming, we like the looks of this boat a lot. We think that, at a glance, she looks like a much bigger vessel. Worst features: Normally a skeg-mounted rudder might result in greater ease of steering and handling compared with a freely suspended rudder. However, there are limits to the size of the skeg, which to our eye have been greatly exceeded on this boat. That is, we see too much wetted surface, which will simply slow the boat."

IMOCA 60 PRB 4. The IMOCA 60 Class yacht PRB 4 was designed by Lauriot-Prévost and G. Verdier and launched in 2010 after being assembled by CDK Technologies based in Lorient, France. The hull was moulded in those of Safran and manufactured at the Larros Shipyard in Gujan Mestras under the direction of Thierry Elluère. The deck will was made at CDK technologies in Port la Forêt. In Italy, near Milan, Refraschini manufacture the internal structure of the boat. The initial keel was made by AMPM, Mothe Achard.

While sailing in the 2020-2021 Vendee Globe with French skipper Kevin Escoffier, who reported issues with a valve at the starboard foil on the 22 November, it suddenly sank on the 30 November, 2000 kilometers south-west of Cape of Good Hope. At the time the skipper was in the third place and was found in his life raft by skipper Jean Le Cam, who was only thirty miles behind him, when Escoffier triggered his emergency beacon. Jean Le Cam was saved in the 2008-2009 Vendee Globe by none other than PRB 3 skipper Vincent Riou at Cape Horn. After having found Escoffier, Jean Le Cam lost visual contact with him as night fell. Eventually, three boats were searching for Escoffier, who was rescued by Le Cam the following morning.

Unmanned aerial vehicles in the French Armed Forces. UAVs in the Armée française are unmanned aerial vehicles (some aircraft) with reconnaissance equipment or weapons on board. The French armed forces use drones for reconnaissance and combat purposes. They are under the command of the French Air & Space Force (Armée de l’Air & de l’Espace).

History 
The French reconnaissance drone program began in 1995 with the purchase of four RQ-5 Hunter UAVs. The French military doctrine differentiates between contact drones with a range of up to 20 km and tactical drones with a range of 20 to 200 km; and so-called "theater drones" with ranges of 200 to 1000 km.

France has been part of a European program to research the development of the Euro MAPE RPAS since 2013. Germany, Spain and Italy are also participating in the development of this medium altitude, long endurance MALE drone. It should be ready for use in 2028.

With the EADS Harfang, France joined the NATO ISAF mission in Afghanistan. The Harfang should be replaced from 2017 by the US General Atomics MQ-9; as of 2020, France had six MQ-9s.

In 2019, the French Ministry of Defense announced that some of the drones would be used for attacks and armed in the future. In December 2019, the French Air Force flew its first drone attack in Mali. The Air Force has been using drones for attacks since.

UAVs

Northrop Gunman RQ-5 Hunter 
The RQ-5 Hunter were procured as reconnaissance drones in 1995.

EADS Harfang / IAI Heron 
The four Harfang (French for snowy owl) drones are used by the French Air Force in Afghanistan and at Opération Serval. The drone is a further developed IAI Heron. As with the original sample from Israel Aerospace Industries, the drone is classified in the Medium Altitude Long Endurance category. While the aircraft was taken over by IAI, EADS and Thales contributed the reconnaissance equipment.

MQ-9 Reaper 
The French Air Force has six MQ9 Reaper from the US company General Atomics. The MALE (medium altitude, long endurance) class drones are used in “Operation Barkhane” to combat Islamist terrorist groups. Three drones are constantly stationed in Niamey, Niger.

After the decision to arm the Reaper was to be equipped with four 250 kg laser-guided GBU-12 bombs each.

Wade supercharger. The Wade supercharger was a Roots-type supercharger designed for internal combustion engines and produced from 1947 by the newly formed Wade Engineering Ltd, of Gatwick Airport, Horley, Surrey. The name 'WADE' comes from Winslett And DEnsham, after Bryan Winslett and Costin Densham.

Company History 
At the end of the war Leslie Mark Ballamy had the idea of repurposing war surplus Marshall cabin air blowers as superchargers for cars. Initially running under his own name, he left the business in 1946 and it was reorganised as North Downs Engineering Co (Nordec). Several members of NORDEC, including the chief designer and the managing director, Marcus Chambers, decided to make their own compressors and to do this created Wade Engineering Ltd at Gatwick airport late in 1947. The early units were sold under the "Ventor" trademark, but soon they became known as Wade superchargers.

The company moved premises to Crowhurst Road, Brighton in 1955. In the 1960s the company was taken over by Howden Engineering Ltd to become Howden Wade Ltd, though they remained at the same premises. 
In 1969 Sir George Godfrey and Partners (Holdings) Ltd merged with James Howden & Company Ltd under James Howden and Godfrey Ltd. This brought the Marshall superchargers (made by Godfrey and Partners) and the Wade superchargers under common ownership. In 1990 Adams Ricardo Ltd purchased the rights to the Wade and Godfrey compressor ranges from Howden.

Technical Details 
The Roots supercharger dates back to the 1860s, and this is the basis for the original Wade supercharger, but with patented modifications incorporated. The first patent of Costin and Densham deals with ways to achieve compression within the Roots-style blower. Although initially focussed on engine superchargers, they were soon to diversify into other application areas, including aircraft cabin pressurisation, refrigeration, reversible air motors and pneumatic conveying of powders and other materials.

Applications 
One of the early successes for the Wade blower was its fitment into the novel Commer TS3 engine. This unusual 2-stroke diesel engine had six opposed pistons operating in three cylinders and relied on a Wade blower to charge the cylinders. They were fitted to Commer and Karrier trucks and to Commer Avenger buses, though the engine was rather noisy for buses.

Mwenga Power Station. Mwenga Dam is a hydroelectric dam in Tanzania, located in the Iringa Region. Its installed capacity is . The Power plant is operated by an Independent Power Producer, Rift Valley Energy.

History
The power plant is part of the Mwenga Hydro and Rural Electrification Project Mini Grid. The plant was built to supply electricity to the Mufundi Tea Plantations and was built approximately 50km from the factory. Along the transmission line route there were 17 un-electrified villages. Rift valley energy decided to connect this villages and provide electricity to these villages.  

The company received support from the ACP-EU Energy Facility and the Tanzania Rural Energy Agency, and in 2012 launched their 4MW Hydro plant and mini-grid. As of 2020, the company supplies energy to the Tea Factory as well as to 32 villages in the Mufindi district servicing 4800 customers. 

Rift Valley Energy operates its power distribution services through Mwenga Power Services Ltd.

Challenges
The plants sells its excess electricity capacity to the national grid to Tanesco, however, has faced poor payment from the state company. As of September 2016, TANESCO owed the plant operator $1.3 million for electricity supplied.

USBM wettability index. The U.S. Bureau of Mines (USBM), developed by Donaldson et al. in 1969,  is a method to measure wettability of petroleum reservoir rocks. In this method, the areas under the forced displacement Capillary pressure curves of oil and water drive processes are denoted as  and  to calculate the USBM index.

USBM index is positive for water-wet rocks, and negative for oil-wet systems.

Bounded USBM (or USBM*) 
The USBM index is theoretically unbounded and can vary from negative infinity to positive infinity. Since other wettability indices such as Amott-Harvey, Lak wettability index and modified Lak are bounded in the range of -1 to 1, Abouzar Mirzaei-Paiaman highlighted the bounded form of USBM (called USBM*) as a replacement of the traditional USBM as 

USBM* varies from -1 to 1 for strongly oil-wet and strongly water-wet rocks, respectively.
