Bismuth hydroxide. Bismuth hydroxide () is non-fully characterised chemical compound of bismuth. It is produced as white flakes when alkali is added to a solution of a bismuth salt and is usually described as bismuth oxide hydrate or bismuth hydrate.

Uses
Bismuth hydrate is a component used in milk of bismuth which is used in gastrointestinal disorders as a protective agent. Aqueous ammonia reacts with bismuth(III) ions to precipitate white bismuth hydroxide.

It is used as an absorbent, and in the hydrolysis of ribonucleic acid.  It is also used in the isolation of plutonium from irradiated uranium.

Japanese Geotechnical Society. The Japanese Geotechnical Society was established in 1949 and had a total of 122 members. Its purpose was to promote technical advances and research activities in the field of geotechnical engineering. From the very outset, its role has been expanding as modern society has placed ever greater demands on it to provide a wide range of services. Since June 2004, The Society has had about 13,000 members, making it one of the largest and most active societies among the more than 100 such societies in existence in Japan. The year 1999 marked its 50th anniversary. The Society has become known by its official abbreviation as the JGS.

The Society joined the International Society for Soil Mechanics and Foundation Engineering in 1950 and has played a significant role on the international stage since then. It had the honor of hosting the Second Asian Regional Conference in 1964, the 9th International Conference in 1977 and the 8th Asian Regional Conference in 1988.

Japanese geotechnicians have also been extremely involved at an international level. Prof. Masami Fukuoka served as the President of the International Society for Soil Mechanics and Foundation Engineering from 1977 to 1981. Prof. Kenji Ishihara also served as the President of the International Society for Soil Mechanics and Geotechnical Engineering for the period 1997–2001. In addition, Prof. Ishihara gave the 33rd Rankine Lecture of the British Geotechnical Society at the Imperial College of Science, Technology and Medicine on 24 March 1993.

Bonomi BS.5 Ballerina. The Bonomi BS.5 Ballerina () was a single seat, medium performance training glider designed and built in Italy in the 1930s.

Design and development
The Ballerina was a high, braced wing aircraft. The wing was mounted on a central pedestal and had a central, straight edged, constant chord centre section, built in two parts, which occupied about a third of the span. There were straight tapered outer panels which carried the ailerons and ended at rounded tips. On each side a pair of V-shaped, faired, steel struts braced the outer ends of the centre section to the base of the fuselage.

The fuselage had an hexagonal cross-section with deep, almost upright sides, its upper surfaces curving down over the nose. It was entirely plywood covered.  The cockpit  was immediately in front of the wing leading edge, placing the pilot's head on the front of the pedestal. A wooden skid with a rubber shock absorbers ran along the underside to form an undercarriage, assisted by a small, faired tail skid.  Under the trailing edge the fuselage dropped down from the pedestal then tapered to the rear.  The tail surfaces were all straight tapered and square tipped, with almost all of the surfaces moving. Enough fixed fin and tailplane was retained to allow aerodynamic balancing via an inset hinge.

The Ballerina was capable of using both ridge and thermal lift. Pilots could use it to gain their C badge.

Operational history
At least two Ballerinas were built, slightly different in dimensions and dihedral and the reconstructed pre-war Italian civil register suggests there may have been a third. Two spent some time in Egypt, brought in by Italians but operated by the Egyptian Aero Club.

Equipment of Strategic Air Command. Strategic Air Command equipment includes weapon systems and ordnance (e.g., strategic weapons such as ICBMs), ground radars and computers (e.g., at SSN 1979-82), and other Cold War devices of the USAF major command.

Special Weapons Emergency Separation System
This system (SWESS), also known informally as the dead man's switch, was a nuclear bomb release system that the United States Air Force Strategic Air Command built into bombers such as the B-52 Stratofortress.  The system's purpose was to ensure that an aircraft's payload of nuclear weapons would detonate in the event of the crew becoming debilitated by enemy defences such as missiles.  Once armed, the system would ensure that the onboard nuclear weapons detonated if the aircraft dropped below a predetermined altitude.

National Aerospace Week. Aerospace Week is an event which celebrates aerospace in the United States. It was established in 2010, and has been celebrated by various government and private organizations, including NASA and the U.S. Department of Commerce. National Aerospace Week was established by an agreement between the U.S. Congress in conjunction with the Aerospace Industries Association . In late 2010 a resolution supporting National Aerospace Week passed both houses of U.S. congress.

In 2012 NAW was held from September 16–22, 2012.

In 2013 the NASA Administrator Charlie Bolden noted the National Aerospace Week.

In 2014, the National Aerospace Week was held Sept. 14-20, 2014. During that week the Governor of the U.S. State of Utah honored the aerospace industry at a luncheon. In 2014 the United States secretary of commerce issued a statement for National Aerospace Week.

Aerospace Week was once again recognized by the U.S Department of Commerce in 2017 through a letter from Secretary of Commerce Wilbur Ross.

In addition to aerospace week, NASA also celebrates National Aviation Day, which was established in the 1939.

Interrupted Streams. Interrupted Streams  Zramim Ktu'im) is a  2010 documentary film co-directed by Swiss Alexandre Goetschmann and Academy Award Nominee Israeli Guy Davidi.

Synopsis
Paths of lives are crossed in one village in the West Bank. Along the broken water pipelines, villagers walk on their courses towards an indefinite future. Israel that controls the water, supplies only a small amount of water, and when the water streams are not certain nothing can evolve. The control over the water pressure not only dominates every aspect of life but also dominates the spirit. Bil'in, without spring water, is one of the first villages of the West Bank where a modern water infrastructure was set up. Many villagers took it as a sign of progress, others as a source of bitterness. The pipe-water was used to influence the people so they would co-operate with Israel's intelligence. The rip tore down the village. Returning to the ancient technique of collecting rainwater-using pits could be the villagers’ way to express independence but the relations between people will doubtfully be healed.

Awards
The Film won the "David Silver Camera" Award of the Warsaw Jewish Film Festival.

Virtual Distributed Ethernet. Virtual Distributed Ethernet  (VDE) is a set of programs to provide virtual software-defined Ethernet network interface controllers (NICs) across multiple devices, typically computers, which are either virtual or physical. It forms part of the Virtual Square project from the Italian Bologna University whose code is available on public servers using free software licenses, mostly GPLv2. Researchers at the Department of Mathematics and Computer Science, Xavier University, Cincinnati OH, US are also working on the project.

It is one of the available networking methods for the Linux Kernel-based Virtual Machine (KVM) and forms part of some Linux distributions such as Ubuntu Precise (12.04 LTS) and Debian

Overview
Software-defined networking is the dynamic creation of virtual network infrastructure that is completely decoupled and independent of any physical network hardware.

Structure
VDE (Virtual Distributed Ethernet) comprises 5 main components:

VDE switch 
A virtual Ethernet switch is equivalent of a physical switch with multiple virtual ports supporting connections from VDE devices.  Supports telnet and a web interface for monitoring and configuration.

VDE plug 
Simulates a plug on the end of a physical Ethernet cable such as the 8P8C.  It forms the connection point between the host and the virtual VDE wire.

VDE wire 
Receives the data from a VDE plug and transports it to another VDE plug.  Obviously performing the same function as the wires within normal Ethernet cabling.

VDE cable 
The combination of 2 VDE plugs and 1 VDE wire is called a VDE cable.

VDE cryptcab 
A connectionless protocol that encrypts the data before transmitting it and that decrypts the data on the other side.  Informally known as VDE Encrypted Cable.
