ObjecTime. ObjecTime Limited of Kanata, Ontario was a software company with the known software product ObjecTime Developer.

Founding of ObjecTime and early years
ObjectTime was founded in 1992 by former employees of Bell-Northern Research who worked on the Telos project. The company developed the product of the same name.

In 1994, the ObjecTime language was renamed to "ROOM" (Real-Time Object-Oriented Modelling) and the Real-Time Object-Oriented Modeling (ROOM) book was published.

In 1998, a UML version of the ROOM language, created as the "UML-RT" profile, was made available.

Acquisition of ObjecTime
Rational Software (developer of the product known as Rational Rose), had been collaborating with ObjecTime Limited since 1997. At the beginning of the year 2000, Rational Software acquired ObjecTime Limited. Their respective products — Rational Rose and ObjecTime Developer — were then merged into a product that was rechristened Rational Rose RealTime.

In 2002, Rational Software was acquired by IBM, which elected to adopt the products.

IBM 37xx. IBM 37xx (or 37x5) is a family of IBM Systems Network Architecture (SNA) programmable communications controllers used mainly in mainframe environments.

All members of the family ran one of three IBM-supplied programs.
Emulation Program (EP) mimicked the operation of the older IBM 270x non-programmable controllers.
Network Control Program (NCP) supported Systems Network Architecture devices.
Partitioned Emulation Program (PEP) combined the functions of the two.

Models

370x series
 3705 — the oldest of the family, introduced in 1972 to replace the non-programmable IBM 270x family. The 3705 could control up to 352 communications lines.
 3704 was a smaller version, introduced in 1973. It supported up to 32 lines.

371x
The 3710 communications controller was introduced in 1984.

372x series

The 3725 and the 3720 systems were announced in 1983. The 3725 replaced the hardware line scanners used on previous 370x machines with multiple microcoded processors.
 The 3725 was a large-scale node and front end processor.
 The 3720 was a smaller version of the 3725, which was sometimes used as a remote concentrator.
 The 3726 was an expansion unit for the 3725.

With the expansion unit, the 3725 could support up to 256 lines  at data rates up to 256 kbit/s, and connect to up to eight mainframe channels.

Marketing of the 372x machines was discontinued in 1989.

IBM discontinued support for the 3705, 3720, 3725 in 1999.

374x series
 The 3745, announced in 1988, provides up to eight T1 circuits. At the time of the announcement, IBM was estimated to have nearly 85% of the over US$825 million market for communications controllers over rivals such as NCR Comten and Amdahl Corporation. The 3745 is no longer marketed, but still supported and used.
 The 3746 "Nways Controller" model 900, unveiled in 1992, was an expansion unit for the 3745 supporting additional Token Ring and ESCON connections. A stand-alone model 950 appeared in 1995.

Successors
IBM no longer manufactures 37xx processors. The last models, the 3745/46, were withdrawn from marketing in 2002. Replacement software products are Communications Controller for Linux on System z and Enterprise Extender.

Clones
Several companies produced clones of 37xx controllers, including NCR COMTEN and Amdahl Corporation.

Lockheed Martin Cormorant. The Cormorant was a tailsitter project under development at Lockheed Martin's Skunk Works research facility until 2008 when its contract for development was cancelled. It is named after a species of diving bird in reference to its intended role as a submarine-launched UAV. It was hoped that it could provide all- weather ISR&T, bomb/battle damage assessment, armed reconnaissance, and special operation forces mission support.

Development
The U.S. Navy's s, feature large, , , tubes to launch Trident missiles. Researchers at Skunk Works had the idea of creating a drone aircraft that can be stored in those missile tubes.

DARPA (Defense Advanced Research Projects Agency) provided funding for tests of models and some of the systems on board the Cormorant. The tests were completed by September 2006. After the tests were complete, DARPA was to determine whether it will fund a flying prototype. While achieving goals and capabilities during tests, DARPA cancelled the contract due to budget cuts in FY08.

Design
While in the tube, the aircraft's wings are folded around itself. The Cormorant, while floating to the surface, unfolds its wings and prepares itself for launch. Rockets then assist the aircraft with lifting off from the water's surface.

A normal aircraft would never survive the pressures that are encountered at a launch depth of 150 ft (46 m). To prevent corrosion, the Cormorant was made from titanium, and to resist crushing, empty spaces were taken up with plastic foam. The interior of the craft was filled with a pressurized inert gas. To keep the Cormorant watertight, the doors, inlets, and any covers required inflatable seals.

One principal means of defense for a submarine is the ability to remain hidden underwater. Thus having an aircraft lift off near the submarine or come directly back to the submarine after its objective is complete would give away the submarine's position. To combat this, the submarine was to slip away while the Cormorant is floating to the surface. After its objective has been completed, the submarine was to transmit rendezvous coordinates to the Cormorant. A robotic retrieval vehicle was then to fetch the drone after it has landed on the surface of the water.

Stannabenzene. Stannabenzene (C5H6Sn) is the parent representative of a group of organotin compounds that are related to benzene with a carbon atom replaced by a tin atom. Stannabenzene itself has been studied by computational chemistry, but has not been isolated.

Stable derivatives of stannabenzene
Stable derivatives of stannabenzene have been isolated. The 2-stannanaphthalene depicted below is stable in an inert atmosphere at temperatures below 140 °C. The tin to carbon bond in this compound is shielded from potential reactants by two very bulky groups, one tert-butyl group and the even larger 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl or Tbt group. The two Sn-C bonds have bond lengths of 202.9 and 208.1 pm which are shorter than those for Sn-C single bonds (214 pm) and comparable to that of known Sn=C double bonds (201.6 pm). The C-C bonds show little variation with bond lengths between 135.6 and 144.3 pm signaling that this compound is aromatic.

Tbt-substituted 9-stannaphenanthrene was reported in 2005. At room temperature it forms the [4+2] cycloadduct.

Tbt-substituted stannabenzene was reported in 2010. At room-temperature it quantitatively forms the DA dimer.

Anderson Hall (Lexington, Kentucky). Mechanical Hall (or Old Anderson Hall or Dicker Hall) at the University of Kentucky, was completed in January 1892 and served as the home to the engineering department. It was known as Dicker Hall by the 1930s and was renamed Anderson Hall in 1948. The building stood as a modern engineering complex, teaching such courses as nuclear engineering, gas dynamics, motion and time study, power plants, heat transfer and thermodynamics, as well as air conditioning. In 1939 the construction of three buildings and the Wendt shop next to Dicker Hall comprised the quadrangle. From the 1940s to the 1960s it is the third largest department in the college of engineering. It was named after F. Paul Anderson, who became the first dean of the College of Engineering on September 18, 1918. Old Anderson Hall was razed in August 1964. Immediately after F. Paul Anderson Tower begins construction and was dedicated April 8, 1967.

Ford Reflex. The Ford Reflex (or REFL3X, as spelled on the vehicle nameplate) was a concept car introduced at the 2006 North American International Auto Show that, according to Ford, "proved small cars could be bold and American". It was a technological showcase that included solar panel-powered headlights, an integrated child seat, a baby cam with a monitor mounted on the dash, inflatable rear safety belts, and an interior quieted by ground rubber taken from Nike athletic shoe outsoles. A production version of the Reflex design has never been announced. It featured an advanced diesel-electric hybrid engine with new-generation lithium ion batteries that could help deliver up to  of diesel fuel, and could accelerate the vehicle from 0 to  in 7 seconds.

The concept featured an electric motor on the rear axle in addition to its hybrid propulsion system on the front axle. The rear motor provided all wheel drive capability, improved driving dynamics, and the fuel economy benefited of a full hybrid vehicle.  Reflex's energy was stored in a new-generation lithium-ion battery pack, using the same technology found in cell phones. Ford was the first manufacturer to produce an electric vehicle using this type of battery system when it introduced the electric Ford Ka research vehicle in 2000. Also contributing to Reflex's power and performance were unique headlamps and taillamps that integrated solar panels. The Ford-patented battery-charging lighting system improved fuel economy by using the sun's power to charge the on-board batteries, while capturing and reusing the daylight at night.

The Reflex featured 2+1 seating, with a center-mounted rear "love seat" for 2 children or one adult, that also included a fold-out rear-facing child seat.  "Ford Reflex is a small car that doesn't feel small," said Freeman Thomas, director, Ford North American Strategic Design. "It is a gorgeous sporty car that delivers guilt free performance with a hybrid engine. And thanks to its innovative approach to the interior, it has space for growing families."

Reflex was set off with Ford's three-bar grille – made of high-strength anodized extruded aluminum, which was hand polished to a matte finish. The concept's shoulder line flowed upward to the B-pillar and back down into the wheel arch. Reverse butterfly doors aid vehicle ingress and egress.

The Reflex concept car was similar in size and general configuration as the Mazda Kabura concept, and if they were both ordered into production could share a common platform, with styling and powertrain differences to set the pair apart.  For example, while the Kabura concept included a 2.0L 16 valve DOHC piston inline-four engine, a production Kabura could have ended up with a rotary engine, as used in the Mazda RX-8.  The Reflex would likely have gotten a more conventional gasoline or diesel (or hybrid) engine.

Portland Project. The Portland Project is an initiative by freedesktop.org aiming at easing the portability of application software between desktop environments and kernels by designing cross-platform APIs and offering implementations thereof as libraries to independent software vendors (ISVs).

The project was taken to establish a greater foothold of Linux and other Unix-like operating systems in the desktop market. It aims at resolving a number of key factors that are believed to reduce the adoption rate of Linux distributions as operating system of choice for desktop computers at home or in the office.

While the Tango Desktop Project was started to give users a more unified graphical experience, the Portland Project is intended to ease the porting of desktop applications to Linux for independent software vendors (ISVs). The project goal is to let software developers worry less about the desktop environment a distribution is using, and thus bring it on more common ground with Microsoft Windows and macOS in this particular area.

In 2006, the project released Portland 1.0 (xdg-utils; "Cross Desktop Group Utilities"), a set of common interfaces for desktop environments. A key part of the interface is a common MIME type database for icons and programs associated with file types.

The project has Alex Graveley (GNOME) and George Staikos (KDE) as two of the task force leaders, who will look to gain feedback from ISVs, integration possibilities, and possibly create a draft implementation as well.

The initial Portland Project meeting, held in Portland, Oregon, was sponsored by the Open Source Development Labs (the predecessor of the Linux Foundation). At the start of that initial meeting, Nat Friedman of Novell came up with the project name: "well, we are here in Portland... how about the Portland Project?"

Nyerereite. Nyerereite is a very rare sodium calcium carbonate mineral with formula Na2Ca(CO3)2. It forms colorless, platey pseudohexagonal orthorhombic crystals that are typically twinned. It has a specific gravity of 2.54 and indices of refraction of nα=1.511, nβ=1.533 and nγ=1.535. Nyerereite is not stable in contact with the atmosphere and rapidly breaks down. Collection specimens must be kept in a sealed argon environment.

It has a Hermann–Mauguin notation of mm2 and the respective space group is Cmc21. In nature Nyerereite is naturally twinned and is pseudohexagonal with triad twinning; meaning that this is a six sided crystal that apparently has a hexagonal shape but is not in the hexagonal system. Triad twinning is the intergrowth of three orthorhombic crystals that turn at their center and form hexagonally shaped crystals. Nyerereite is biaxial negative, and has a 2v of 29 degrees. It shows a center acute bisectrix and a birefringence of approximately 0.023. At high temperatures or just erupted lava nyerereite is uniaxial and shows an interference color of second order blue when twinning is not present, and  when twinning is there the interference color of nyerereite is first order grey.

Special characteristics
Since nyerereite is very unstable when it reaches the surface it creates pseudomorphs, which is basically the process by which the rock appearance and dimensions remain constant but the main mineral component is replaced by another. McKie (1976) categorized nyerereite into two different categories, high and low nyerereite. There are two types because the Ol Doinyo Lengai lavas are very soluble and hygroscopic; when they come in contact with water or the atmosphere, the lava changes physically and chemically. Therefore, when nyerereite is at high temperature or warm we have what McKie (1976) calls high nyerereite, but when it cools down and gets hydrated we have  pirssonite that has a chemical formula of  Na2Ca(CO3)2·2(H2O).

Occurrence and discovery

It was first recognized and described by J.B. Dawson from the Ol Doinyo Lengai carbonatite lavas of Arusha Region in 1963 and named in honor of the president of Tanzania, Julius Nyerere (1922–1999). In the carbonatite lava it is associated with the potassium-bearing gregoryite. It has also been reported from the Afrikanda alkaline intrusive complex, in the Kola Peninsula, Russia.
