Parker 2nd Ranger. The Parker 2nd Ranger, also called the Parker Ranger is an American mid-wing, single-seat motor glider that was designed and constructed by W.L. Parker of La Grande, Oregon, first flying in 1967.

Design and development
Parker originally built the Ranger and equipped it with a  and a  propeller that was unable to provide enough thrust to allow the aircraft to take-off. The engine was replaced with a Richter  powerplant which rectified this defect. The engine is retractable and mounted behind the cockpit.

The aircraft is constructed from aluminium. The  wing employs a laminated aluminium spar and a NACA 4418 airfoil. The Ranger is not equipped with any glidepath control devices, such as dive brakes. The landing gear is a single centreline mainwheel plus a nose-mounted second wheel to allow taxiing.

The aircraft was registered with the Federal Aviation Administration in the Experimental - amateur-built category. Only one was built.

Barrow Bridge, Bolton. Barrow Bridge is a model village in the north-west outskirts of Bolton in Greater Manchester, England. It was created in the Industrial Revolution but since the demolition of the mills is now a residential village.

History
John and Robert Lord opened a cotton mill using water power from the Dean Brook which powered spinning mules invented by Samuel Crompton. The brothers built 13 cottages near the mill for workers. In 1830 Thomas Bazley and Richard Gardner bought and demolished the mill, replacing it with Dean Mills, twin six-storey steam powered mills situated on the east side of the brook at the entrance to the village. They created a model village for the mill workers on the hill top accessed by a flight of stone steps, with rows of cottages, a shop and an educational institute. Houses for the managers were built a short distance away, overlooking the brook. William Callender bought Dean Mill in 1861. The company went out of business after his death and the mill was demolished in 1913.

Benjamin Disraeli visited the village in 1840, it is the basis of the fictional village Millbank in his novel, Coningsby, published in 1844.

Governance
Historically, the Barrow Bridge area was part of the township of Halliwell in the ancient parish of Deane. When the south-eastern part of the township became part of the Municipal Borough of Bolton in 1877 the remaining north-western area, including Barrow Bridge, became known as Halliwell Higher End until 1894 when its name was changed to Smithills.

Since 1974, Barrow Bridge has been part of the Smithills ward, one of Bolton Council's 20 electoral wards.

Converged network adapter. A converged network adapter (CNA), also called a converged network interface controller (C-NIC), is a computer input/output device that combines the functionality of a host bus adapter (HBA) with a network interface controller (NIC). In other words, it "converges" access to, respectively, a storage area network and a general-purpose computer network.

Support 
Some products were marketed around 2005 with the term C-NIC which combined iSCSI storage functionality with Gigabit Ethernet.
Later products used the marketing term converged network adapter (CNA), combining  Fibre Channel over Ethernet with 10 Gigabit Ethernet, for example.

Brocade
Brocade Communications Systems offers two types of CNAs, with  PCI Express generation 2.0 interfaces. The only difference between the two models are the number of interfaces on the cards: one or two. The two port model will allow connection to two different switches to create a redundant configuration without having to use two PCI slots.

Broadcom
In 2009 Broadcom entered the CNA market. Broadcom offers their CNAs under their own brand name but also sell the application-specific integrated circuits and other related components to others. Their intended customers are the larger builders of server systems such as Dell and HP. These vendors can then include the ten Gigabit CNA with their servers: as embedded interface on the motherboard (LOM or LAN on motherboard), via a mezzanine card in blade servers or as PCI extension-card.

Emulex
Emulex offers CNAs under the Emulex brand name as the OneConnect ten Gigabit series of dual port optical and copper adapters.  They also OEM their adapters for Cisco, Dell, EMC, Fujitsu, HDS, HP, IBM and NetApp.

QLogic
QLogic offers CNAs via their QLogic 8200 & 8300 series Converged Network Adapters. They offer single and dual port PCI cards with copper or optical fibre interfaces. QLogic CNAs are available under the QLogic brandname and as OEM cards. The QME CNA and drivers were supported by Citrix, NetApp, EMC and IBM.

Hewlett-Packard
HP claims that their BL460c G7 was the first blade server that offers FCoE via a LOM (LAN on motherboard) instead of using a PCI slot or mezzanine card.

Dell
Dell uses the QLogic 8100 series in their PowerEdge servers. For the M-series, blade-servers for the M1000e use the custom made dual-port mezzanine card QME8142. For the normal tower and rack servers Dell offers an OEM version of the standard QME8152.

Cisco
Cisco Systems offered Fibre Channel over Ethernet in their Unified Computing System product line via Virtual Interface Cards (VICs). These cards make it possible to create multiple virtual HBAs or NICs within each physical VIC.

Intel
Intel demonstrates how the term Converged Network Adapter is really a marketing term, as they sell the X710-DA2/DA4 adapters  that don't actually support FCoE.

Space Hunter. is a Japan-exclusive video game that was released in 1986 for the Family Computer. The game was developed and published by Kemco, which was then known as Kotobuki System.

Plot
The plot revolves around a robotic revolt led by a robot named De Gaulle in the year 2199 AD. By the explosions of global nuclear war, society has broken up into nine small expulsions, one of them disappeared and Venus collided with another celestial object. Humanity only slightly survived. Its thread of life barely connected to a body, which was rebuilt into a cyborg. The heroine is named Al Tiana and is also apparently a robot who does not support the rebellion. She is out to prove her loyalty to the humans.

1973 raid on al-Mazzah Airport. The 1973 raid on al-Mazzah Airport took place on October 13, 1973, and was one of a series of bombing raids carried out by the Israeli Air Force deep inside Syria during the Yom Kippur War.

Battle
Israeli F-4s and Mirage IIICs approached Al-Mazzah airport to conduct a series of raids to neutralize the bases capable of launching attacks over Israeli airspace. Shortly after crossing into Syrian airspace, the Israeli formations came under heavy fire by Soviet-made Syrian Air Force MiG-21s. The Israeli pilots managed to shoot down two of the MiG-21s and then concentrated their attack on the airbase itself. Using the Mirage IIIC's bombing capabilities, they were able to crater the runways and inflict light ground losses. During the raid a MiG-21 shot down an F-4 Phantom; both the pilot and the navigator survived, but they crashed on hostile ground near the airbase, and shortly after that were rescued by IDF forces. Another F-4 Phantom was severely damaged by anti-aircraft fire from the airbase; the plane was escorted back to Israeli airspace, and safely returned home.

Aftermath
Following the attack, a battle erupted between the IDF and Syrian forces, as the IDF attempted to rescue a pilot and a navigator who ejected from their F-4 Phantom II during the raid. One F-4 Phantom II was crippled during the engagement, but was escorted back to safety despite repeated efforts by the Syrian Air Force to shoot down the crippled aircraft. The raid was primarily an Israeli victory as they sustained minimal losses, compared to the losses of the Syrian Air Force, which lost the airbase and two MIG-21's.

Hoverwork BHT130. The Griffon Hoverwork BHT130 is a large hovercraft, designed by Hoverwork and fitted out in St Helens.
The type was found to be too large for the cross-Solent route and was withdrawn after 4 years in service (2007-2011), although other BHT variants are found currently in service around the world in various commercial and civil roles and designated as BHT 130 / 150 / 180.

As a civil passenger hovercraft it seats up to 130 passengers, hence the numerics in its name, the first welded aluminium hull (fabricated by Aluminium Ship Builders, Fishbourne, Isle of Wight) arrived at Hoverwork's St Helens works in August 2005. “BHT” stands for British Hovercraft Technologies.

The first of its kind, named the Solent Express entered cross-Solent service on 14 June 2007; also, in the July of the same year, it was put on trial at a new passenger service between Kirkcaldy and Portobello across the Firth of Forth in Scotland. It remained in service on the Solent until 2011 when it was sold to Griffon Hoverwork Ltd and laid up pending sale.

German submarine U-741. German submarine U-741 was a Type VIIC U-boat built by F Schichau GmbH of Danzig and commissioned on 10 April 1943.

Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-741 had a displacement of  when at the surface and  while submerged. She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of  for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of  for use while submerged. She had two shafts and two  propellers. The boat was capable of operating at depths of up to .

The submarine had a maximum surface speed of  and a maximum submerged speed of . When submerged, the boat could operate for  at ; when surfaced, she could travel  at . U-741 was fitted with five  torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one  SK C/35 naval gun, 220 rounds, and two twin  C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.

Service history
On 5 July 1944, U-741 departed Brest under the protection of 4 Vorpostenboot escort trawlers. Escort Group 12, Royal Canadian Navy, detected the German force on radar and intercepted it, engaging in the vicinity of the Pierres Noires lighthouse (Battle of Pierres Noires) in the late evening. U-741 managed to escape, but one of the German escorts was sunk.

On 15 August 1944, she attacked convoy FTM-69 and torpedoed the Royal Navy Tank Landing ship , 35 miles South East of St. Catherine's Point causing extensive damage and seven fatalities. Although the vessel was beached, she later broke in two and was declared a total loss. Convoy escorts counter-attacked; the corvette  is credited with the destruction of U-741. Orchis rescued one survivor.

The wreck was identified by marine archaeologist Innes McCartney in 2000 near the position given by the Allies.

In five patrols U-741 accounted for the total loss of one warship, for a total of 1,625 tons.

Wolfpacks
U-741 took part in six wolfpacks, namely:
 Coronel 1 (14 – 17 December 1943) 
 Sylt (18 – 23 December 1943) 
 Rügen 2 (23 – 28 December 1943) 
 Rügen 1 (28 December 1943 – 7 January 1944)

Pay (geology). Pay is an expression used in hydrocarbon mining. It denotes a portion of a reservoir that contains economically recoverable hydrocarbons. The term derives from the possibility of  "paying" an income surpassing the costs. Equivalent terms are pay sand or pay zone. Overall interval in which pay volumes occur is the gross pay; smaller portions of the reservoir that meet further criteria for pay (such as permeability and hydrocarbon saturation) are net pay.

Net pay is determined through placing cut offs on properties like permeability, porosity, water saturation or volume of shale. Care needs to be taken to cut out the part of the gross rock volume that has the ability to allow fluids to flow and actually stores hydrocarbons. In other cases when determining "Net Reservoir" the remaining rock is that rock that can still store flow hydrocarbons but is not necessary containing hydrocarbons. When the cut off is based on the ability of the rock to store hydrocarbons this is called "Net Rock".

Scheibe SF-24 Motorspatz. The Scheibe SF-24 Motorspatz () is a West German high-wing, single-seat motor glider that was designed by Egon Scheibe and produced by Scheibe Flugzeugbau.

Derived from the unpowered Scheibe Spatz, the Motor Spatz was described in 1983 by Soaring Magazine as "one of the more primitive of the breed of self-launching sailplanes".

Design and development
The Motorspatz was an early attempt to create a self-launching glider. Scheibe accomplished this by mounting a Hirth engine in the nose of a mostly stock Spatz glider.

The SF-24 is constructed with a welded steel tube fuselage that mounts the monowheel landing gear, with a small tail wheel for ground maneuvering. The wings and tail surfaces are built with wooden structures and covered in doped aircraft fabric covering. The wing has a  span, employs an Mu 14% airfoil and mounts spoilers for glidepath control.

The aircraft was not type certified and 50 were built.

Operational history
In July 2011 there were two Motorspatz registered in the United States with the Federal Aviation Administration, including one SF-24 in the Experimental - Exhibition category and one SF-24B in the Experimental - Research and Development category.

OpenQwaq. OpenQwaq is open source computer software for immersive collaboration, which enables organizations to implement online 3D virtual world workspaces for their specific needs. OpenQwaq is based on the Teleplace technology, a conferencing platform that has been in the market since 2007, with the name Qwaq Forums until 2009.

History

Both OpenQwaq and Teleplace are based on the Squeak open source implementation of Smalltalk and the Croquet Project. The main developers of this family of technologies include Alan Kay, David Smith, Andreas Raab, Ron Teitelbaum, Eliot Miranda and David Reed, whose 1978 doctoral thesis on naming and synchronizations in a decentralized computer system introduced many of the main concepts. Teleplace virtual workspaces were used by companies, universities, organizations and U.S. government agencies, such as the Air Force, Army, Navy and Department of Veterans Affairs for training and collaboration, have applications to telepresence based e-learning, and have been used for popular interactive online technology talks. Teleplace ceased operations in December 2011. 3D ICC Purchased the IP from Teleplace in 2012.  The commercial product is now called Virtend.

Initial release

OpenQwaq was announced on the Teleplace blog and other IT news sites in May 2011.

The initial release of OpenQwaq was functionally equivalent to Teleplace with the exception of the video subsystem used for webcam videoconferencing, video playback and session recording, because the proprietary video codecs used in Teleplace could not be included as open source. Developers have then integrated in OpenQwaq the open source video and audio codecs used in the VLC media player. Following a standard open source technology business model, companies offering value added OpenQwaq hosting and consulting services have been formed. In 2022 3D Immersive Collaboration Corp renamed Immersive Terf to Virtend™

Heinkel P.1073. The Heinkel P.1073 (He P.1073), known also as Strahljäger (Jet fighter), was a fighter project developed for the Luftwaffe by Heinkel aircraft manufacturing company during the last years of World War II.

Development
In 1944 Heinkel produced different designs of the project using either two Heinkel HeS 011 or two BMW 003 axial-flow turbojets. One of the turbojets was placed on top of the fuselage and the other in a ventral position. The engine below the fuselage was placed asymmetrically in order to provide space for the retractable front undercarriage wheel. The designs of this aircraft would be used by Heinkel to develop the He 162 Volksjäger, which used only one turbojet engine, towards the end of 1944.

Variants
Heinkel produced twenty variants of the project between July 6 and October 3, 1944. All variants would have been armed with two 30 mm MK 108 cannons.

He P.1073 01 4 
This was the original design of the jet-powered fighter project. It had a v-tail and swept wings fitted with a streamlined 500 liter fuel tank on each wing.

He P.1073 01 8 
Project for a high-altitude reconnaissance aircraft. It was also a slightly asymmetric jet-powered plane like the earlier design, but with the cockpit located at the front end of the fuselage. The design included an alternative version with a high aspect ratio upswept wing.
