Bucciero SVIT. The Bucciero SVIT, (SVIT - Studio per un Velivolo da Instruzione e Turismo, English:study of an aircraft for training and touring), was a single engine, mid-wing, training and touring aircraft designed and constructed by a group of Alitalia staff in the 1960s, at least two of which were built.

Design and development
The all-metal, two-seat Bucciero SVIT was designed by an Alitalia airline pilot, Renato Bucciero.  Gastone Canal, an engineer with the same airline, assisted with its construction which began in July 1966.  Later, plans for the production of three more, slightly refined SVITs involved nine more of Bucciero's Aeritalia colleagues.

The SVIT was a fairly conventional single-engined aircraft with side-by-side seating for two, though Bucciero favoured a mid wing design rather than the more common low wing.  The wing had constant chord, rounded tips and dihedral (aircraft) of 2.5° throughout, built around a two spar torsion box.  Its trailing edge carried slotted flaps.  The rectangular, low set, tailplane was of the all moving type with full span anti-tabs and the straight tapered fin and rudder was assisted by a small dorsal extension and an underside fin.

The fuselage forward of the cabin was circular in cross section, built around a tube steel frame. Non-inflammable plastic was used for the engine cowling, with aluminium sheet behind. The cabin and tapering rear fuselage had a rectangular cross section and was a semi-monocoque structure.  The port side of the Plexiglass canopy hinged upwards for access to the cabin, which was fitted with dual controls.  A port side door provided access to a baggage compartment behind the seats.  The fixed tricycle undercarriage had fuselage mounted cantilever steel spring legs; the main wheels had brakes and the nosewheel was steerable.

Initially the SVIT was powered by an 85 hp (63 kW) Continental C85 flat four engine.  This was used for its first flight (2 July 1968) and took it through to certification in April 1969.  That engine was then immediately replaced with a 100 hp (75 kW) Continental O-200.  There were plans to build three more SVITs with this engine, modifications to the undercarriage, a sliding canopy and a rounded rear decking but only one was completed.  This SVIT 70 was scheduled to fly in the Summer of 1971.  Registered I-FABO, it was exhibited at the Turin Air Show in June 1972.

System Service Descriptor Table. The System Service Descriptor Table (SSDT) is an internal dispatch table within Microsoft Windows.

Function 

The SSDT maps syscalls to kernel function addresses.
When a syscall is issued by a user space application, it contains the service index as parameter to indicate which syscall is called. The SSDT is then used to resolve the address of the corresponding function within ntoskrnl.exe.

In modern Windows kernels, two SSDTs are used: One for generic routines (KeServiceDescriptorTable) and a second (KeServiceDescriptorTableShadow) for graphical routines. A parameter passed by the calling userspace application determines which SSDT shall be used.

Hooking 

Modification of the SSDT allows to redirect syscalls to routines outside the kernel. These routines can be either used to hide the presence of software or to act as a backdoor to allow attackers permanent code execution with kernel privileges. For both reasons, hooking SSDT calls is often used as a technique in both Windows kernel mode rootkits and antivirus software.

In 2010, many computer security products which relied on hooking SSDT calls were shown to be vulnerable to exploits using race conditions to attack the products' security checks.

1966 Felthorpe Trident crash. On 3 June 1966, a newly built Hawker Siddeley Trident jetliner crashed during a pre-delivery test flight near the village of Felthorpe, Norfolk, England, killing all four crew.  The aeroplane had entered a deep stall from which the crew were unable to recover.  It was the first loss of a Trident aircraft.

Aircraft and crew

Aircraft 
The aircraft involved was a tri-jet Hawker Siddeley Trident 1C, registration  that was about to be delivered to British European Airways.

Crew
The crew were pilots Peter Barlow and George Errington, and technicians E. Brackstone-Brown and G.W. Patterson.

Accident flight

The aircraft was making its first flight, which was a routine test flight to enable the aircraft's Certificate of Airworthiness to be issued.  There were four crew on board.  The aircraft took off from Hatfield Aerodrome at 16:52. Tests established that the stick shaker operated at , and that stall recovery system operated at .  The crew then disconnected the stall warning systems in order to ascertain the actual margin left after the warning had been given before the aircraft stalled.  On this particular flight, the aircraft was being operated with its centre of gravity towards its aft limit.

Shortly after 18:30, the pilot reported that the aircraft was in a "superstall".  At the time, the aircraft was observed to be configured for landing. It was at an altitude of .  The nose was seen to pitch up by 30 to 40° before the aircraft turned to port, followed by the starboard wing dropping.  Although full power was applied, the aircraft entered into a flat spin, and crashed at Felthorpe, killing all on board.  It was not fitted with an anti-spin parachute.  The site of the accident was in a field adjacent to Felthorpe Airfield.

Investigation
The Accidents Investigation Branch opened an inquiry into the accident. The investigation found that accident was the result of the pilot delaying recovery manoeuvres for too long, thereby allowing the aircraft to enter a deep stall from which it was impossible to recover.

Birds (advertisement). "Birds" is a television commercial for the Washington Lottery; it won a Silver Lion at the 2009 Cannes Lions International Advertising Festival, and "Best in Show" at the 2009 National ADDY Awards. SHOOT magazine placed it on their Top 10 list for Summer 2008.

First broadcast in June 2008, it depicts three flightless birds—a penguin, a chicken, and an emu—being taken hang-gliding (the chicken and the penguin are shown wearing harnesses strapped to the chest of the glider pilots; the emu's harness is suspended between two gliders).

The images of the birds in mid-air were produced by compositing video of the birds in their harnesses with video of the gliders in flight.

California Reclamation Districts. California Reclamation Districts are legal subdivisions within California's Central Valley that are responsible for managing and maintaining the levees, fresh water channels, or sloughs (pronounced slü), canals, pumps, and other flood protection structures in the area. Each is run autonomously and is run by an elected board and funded with taxes to property owners in the local area. However, the Central Valley Flood Protection Board has the power to determine that a district is not satisfactorily maintaining the structures and causing the California Department of Water Resources to declare an area as a maintenance area.

History
A reclamation district represents former wetlands that were drained for agriculture. The reclamation districts were created by acts of State Legislature, mostly in the early 1900s in order to allow land to be used for agriculture. For example, Reclamation District No. 1000 was created on April 8, 1911. Reclamation was usually accomplished by the introduction of levee systems along with other flood control mechanisms to prevent flooding in wetland areas. The levees also enabled large amounts of silt runoff from gold mining to be channeled all the way out to the San Francisco Bay area, even at water levels that would normally flood the banks and therefore move too slowly for sediment transport.

Most of the structures were built as part of the Central Valley Project authorized by congress in 1917 and ultimately finished in 1960 by the US Army Corps of Engineers. There are about  of project levees as well as many pumps, canals, sloughs, bypasses and other flood protection structures which became the responsibility of the State of California in 1960. In total, there are around  of levees (if the non-project levees are included) in the State of California. Non-project levees are the levees which do not fall under the auspices of the state government and are considered the responsibility of the individual land owners. The vast majority of the water in the California watershed (or drainage basin) falls into the central valley area which drains into the Sacramento–San Joaquin River Delta, and so this is also where most of the levee systems and reclamation districts fall.

Nabalamprophyllite. Nabalamprophyllite has a general formula of . The name is given for its composition (Naba, meaning sodium, Na and barium, Ba) and relation to other lamprophyllite-group minerals. Lamprophyllite is a rare Ti-bearing silicate mineral usually found in intrusive igneous rocks.

Nabalamprophyllite is monoclinic, which means crystallographically, it contains three axes of unequal length and the angles between two of the axes are 90°, and one is less than 90°. It belongs to the  space group P2/m. The mineral also has an orthorhombic polytype (nabalamprophyllite-2O). This mineral belongs to the space group Pnmn. In terms of its optical properties, nabalamprophyllite is anisotropic which means the velocity of light varies depending on direction through the mineral. Its calculated relief is 1.86 - 1.87.  Its color in plane polarized light is green-brown, and it is weakly pleochroic.

The mineral has only been found in Russia, usually in association with coarse-grained igneous rocks called pegmatites. The type localities are the Inagli alkaline–ultrabasic massif, Yakutia and the Kovdor alkaline–ultrabasic massif in the Kola Peninsula.

Kakuda Space Center. is a facility of the Japan Aerospace Exploration Agency (JAXA), located in the city of Kakuda in Miyagi Prefecture in northern Japan, specializing in the development and testing of rocket engines and space propulsion systems. The LE-5 (including the LE-5A/LE-5B version), and the LE-7 (including the LE-7A version) rocket enginese were developed at the Kakuda Space Center.

History
The predecessor to the Kakuda Space Center was established in 1965 as the "Kakuda Branch Laboratory" of the National Aerospace Laboratory of Japan under the aegis of the Science and Technology Agency. In 1978, the National Space Development Agency (NASDA) constructed the "Kakuda Rocket Development Center" on the same campus. Its purpose was to engage in basic research and development to raise the level of Japanese rocket propulsion technology. From the late 1980s, the Center also began research into space plane propulsion, especially scramjet technology and advanced materials research for reusable space engines.

In October 2003, the three separate Japanese space agencies, the Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory (NAL), and NASDA, merged to form the Japan Aerospace Exploration Agency (JAXA). In 2005, the Kakuda Space Center was officially renamed the "Kakuda Space Propulsion Technology Research Center".

Noshiro Rocket Testing Center. The  is a facility of the Japan Aerospace Exploration Agency (JAXA), located on the coast of the Sea of Japan in the city of Noshiro in Akita Prefecture, Japan.

History
The Noshiro Rocket Testing Center (NTC) was established in 1962 as one of the affiliated facilities of the Institute of Industrial Science of the University of Tokyo, which became the Institute of Space and Astronautical Science (ISAS) in 1964. The testing center was involved in the development and testing of sounding rockets and the solid-fuel rocket engines which were used on the Mu series of launch vehicles.

From 1975, the Noshiro Testing Center was involved in the research, development and testing of liquid-fuel rocket engines. With the M-V launch vehicle program, the facilities were extensively upgraded with a large solid motor air combustion test building and an upper motor high altitude performance test facility completed by 1992. The static firing test for the M-V rocket engines took place at Noshiro.

In addition, a successful static test firing of the ATREX, an experimental precooled jet engine that works as a turbojet at low speeds and a ramjet up to Mach 6.0 occurred in 1992. From 1998, the site has been active in the Reusable Vehicle Testing program to develop an air-breathing engine which uses less fuel than a rocket and can therefore transport a larger payload.

Engineering Equation Solver. Engineering Equation Solver (EES) is a commercial software package used for solution of systems of simultaneous non-linear equations. It provides many useful specialized functions and equations for the solution of thermodynamics and heat transfer problems, making it a useful and widely used program for mechanical engineers working in these fields. EES stores thermodynamic properties, which eliminates iterative problem solving by hand through the use of code that calls properties at the specified thermodynamic properties. EES performs the iterative solving, eliminating the tedious and time-consuming task of acquiring thermodynamic properties with its built-in functions.

EES also includes parametric tables that allow the user to compare a number of variables at a time. Parametric tables can also be used to generate plots. EES can also integrate, both as a command in code and in tables. EES also provides optimization tools that minimize or maximize a chosen variable by varying a number of other variables. Lookup tables can be created to store information that can be accessed by a call in the code. EES code allows the user to input equations in any order and obtain a solution, but also can contain if-then statements, which can also be nested within each other to create if-then-else statements. Users can write functions for use in their code, and also procedures, which are functions with multiple outputs. 

Adjusting the preferences allows the user choose a unit system, specify stop criteria, including the number of iterations, and also enable/disable unit checking and recommending units, among other options. Users can also specify guess values and variable limits to aid the iterative solving process and help EES quickly and successfully find a solution.

The program is developed by F-Chart Software, a commercial spin-off of Prof Sanford A Klein from Department of Mechanical Engineering
University of Wisconsin-Madison.

EES is included as attached software for a number of undergraduate thermodynamics, heat-transfer and fluid mechanics textbooks from McGraw-Hill.

It integrates closely with the dynamic system simulation package TRNSYS, by some of the same authors.
