Genoa Joint Laboratories. Genoa Joint Laboratories (GJL) is a scientific research activity founded in 2002, combining expertise in electroceramics and electrochemistry of three facilities: National Research Council - Institute for Energetics and Interphases (CNR-IENI), Department of Chemical and Process Engineering with University of Genova (DICHeP), and the Department of Chemistry and Industrial Chemistry with University of Genova (DCCI), all located in Genoa, Italy.

Research focus
The focus of GJL's research is across four fundamental factors that are critical to production and implementation of High-Temperature Solid Oxide Fuel Cells:
 Synthesis and sintering of electrolytes
 Cell design, testing and analysis
 Electrocatalysis
 Interconnects
Bridging these four factors, GJL is engaged in research in six interdependent fields:
 Synthesis of cathode and anode materials for IT-SOFCs
 Synthesis of protonic electrolyte for IT/LT-SOFCs
 Production of engineered electrodes
 Electrochemical kinetics at the anode and cathode for SOFCs and MCFCs
 Study of metallic interconnect behaviour
 Model the distribution of active sites in composite electrodes
Using Electrochemical Impedance Spectroscopy, it has been found that the rate determining step of the oxygen reduction reaction changes between 700 and 800 °C. This is important because it proves the existence of a critical temperature, previously only theorised, for activation of the entire composite cathode volume close to 750 °C. Below this temperature, ionic transport is slower; as the temperature increases, so does ionic activity through the cathode. Additionally, GJL researchers have demonstrated that the volume ratio between Lanthanum Strontium Manganite (LSM) and Yttria Stabilised Zirconia (YSZ) composite cathodes which is close to 1:1 gives the best electrochemical activity because of the extension of the three phase boundary (TPB) in the electrode. By means of impedance analysis and potentiodynamic polarisation, this finding has strong implications for optimal SOFC design.

GNR Class H3. The Great Northern Railway Class H2 and H3 (classified K1 and K2 by the LNER) was a class of 2-6-0 steam locomotive designed for mixed-traffic work.

The class was created as a locomotive which could haul heavier goods trains at speeds of up to 40 mph. The class were later developed into the more powerful H4 (LNER K3) class. After formation of the London and North Eastern Railway, the type became known as class K1 and K2 and was adopted as an LNER standard design. They got the nickname "Ragtimers" because of their lively nature when running at speed and their use of Walschaerts valve gear which was uncommon on the GNR at the time.

Construction 
The ten K1s were built at the GNR's Doncaster Works in 1912–1913, to the design of Nigel Gresley.  Five batches of K2s, also to the design of Gresley, were built at Doncaster, the North British Locomotive Company, and Kitson and Company between 1914 and 1921. These were the first design to incorporate Gresley's patented double swing link pony truck design.

Use 
They were excellent mixed-traffic locomotives, but began to be displaced by the larger and stronger K3s. They were moved to former Great Eastern and North British lines to supplement existing engines. Twenty K2s were fitted with Westinghouse pumps so they could pull passenger trains from Liverpool Street on the Colchester and Cambridge lines.

Rebuilding 
No. 4635 was rebuilt from K1 to K2 in 1920. No. 4631 was rebuilt in 1921. No further K1s were rebuilt until 1931, when a shortage of K1 boilers necessitated rebuilds. The remaining eight were rebuilt between 1931 and 1937, making the K1 class extinct.

Numbering 
The K1s were numbered 1630–1639 by the GNR, and became LNER 4630-4639. The K2s were numbered 1640–1704 by the GNR, and became LNER 4640-4704. In the LNER's 1946 renumbering programme, the K2s were renumbered 1720–1794, and they later became British Railways 61720–61794.

Names 
None of the K1s were named. However, some of the K2s based in Scotland received names in 1933–34.

Withdrawal 
All K2s were withdrawn and scrapped between 1955 and 1962.

Virginia Coast Reserve Long-Term Ecological Research. The Virginia Coast Reserve Long-Term Ecological Research (VCR/LTER) project is funded by the National Science Foundation. The VCR/LTER project's research activities focus on the mosaic of transitions and steady-state systems that comprise the barrier-island/lagoon/mainland landscape of the Eastern Shore of Virginia. Research is conducted in mainland marshes, the lagoon system behind the barrier islands, and on the islands themselves, particularly Hog Island. The VCR/LTER began operation in 1987. It initially focused on geophysical controls (e.g., storms) on coastal ecosystems. In 1992-1994 it broadened that focus to address the concept of ecological state change, which was linked in 1994-2000 to relationships between free surfaces (land, sea, freshwater table). More recent work  (2000-2006), added a hypsometric perspective, which provides an alternate way of examining ecological patterns on the coastal landscape. It makes extensive use of the Virginia Coast Reserve of The Nature Conservancy.  

The VCR/LTER is a member of the Long Term Ecological Research Network, and is administered by the Department of Environmental Sciences of the University of Virginia. Its field research headquarters is at the Anheuser-Busch Coastal Research Center of the University of Virginia in Oyster, Virginia. The research site received new funding from the National Science Foundation in 2018 which will allow the research team of Karen McGlathery, Michael Pace, Patricia Wiberg, John Porter, and to continue research projects into the impact of climate change on coastal barrier oceans.

Andrew H. Bobeck. Andrew H. Bobeck (October 1, 1926 – December 14, 2017) was a Bell Labs researcher best known for his invention of bubble memory.

Bobeck was born in Tower Hill, Pennsylvania.

In 1975, Bobeck was elected a member of the National Academy of Engineering for his contributions to the field of magnetic bubbles that have produced a new class of electronic devices.

Education 
In 1948, Bobeck earned a Bachelor of Science degree in EE from Purdue University. In 1949, Bobeck earned a Master of Science degree in EE from Purdue University.

Career 
Bobeck was a member of United States Navy's V12 Program.

In 1949, Bobeck joined Bell Laboratories. Bobeck helped design communication and pulse transformers and then one of the first solid-state digital computers. Starting in 1956 he devoted his efforts to the development of magnetic logic and memory devices. He invented the twistor memory in the late 1950s, and in the late 1960s bubble memory based on magnetic domains in orthoferrites and garnets. In 1989 he retired from AT&T's Bell Labs.

Bobeck held more than 120 patents, and was a member of the National Academy of Engineering and an IEEE Fellow. He received an honorary Doctor of Engineering degree from Purdue in 1972, the 1975 IEEE Morris N. Liebmann Memorial Award, and the 1987 IEEE Magnetics Society Achievement Award. He was also presented with the Stuart Ballantine Medal for Computer Sciences by The Franklin Institute in 1973.

Tin cry. Tin cry is the characteristic sound heard when a bar made of tin is bent. Variously described as a "screaming" or "crackling" sound, the effect is caused by the crystal twinning in the metal. The sound is not particularly loud, despite terms like "crying" and "screaming".  It is very noticeable when a hot-dip tin coated sheet metal is bent at high speed over rollers during processing.

Tin cry is often demonstrated using a simple science experiment. A bar of tin will "cry" repeatedly when bent until it breaks. The experiment can then be recycled by melting and recrystallizing the metal. The low melting point of tin, , makes re-casting easy. Tin anneals at reasonably-low temperature as well, normalizing tin's microstructure of crystallites/grains.

Although the cry is most typical of tin, a similar effect occurs in other metals, such as niobium, indium, zinc, cadmium, gallium, and solid mercury.

Motor coach (rail). A motor coach (international usage) or motorcar (US usage) is a self-propelled passenger rail vehicle also capable of hauling a train. With multiple unit train control, one operator can control several "motor coaches", possibly even combined with locomotives, efficiently in the same train, making longer trains possible. 

Motor coaches can replace locomotives at the head of local passenger or freight trains. Especially electrified narrow gauge lines on the European continent often saw this form of operation. Many of these railways closed down, and many others changed to electric multiple units. However, a few lines in Switzerland, Italy and Austria still work with train consists hauled by motor coaches. It can be expected that the Bernina line of Rhaetian Railway will continue for a long time to be operated with motor coaches pulling passenger and freight trains.

George Wyllie (British Army soldier). George Cameron Wyllie, GC (25 December 1908 – 1 February 1987) of the Royal Engineers was awarded the George Cross for the heroism he displayed on 12 September 1940 when a  bomb fell near St Paul's Cathedral in Deans Yard.  It took three days to dig the bomb out of soft soil, work made even more dangerous by a fire at a fractured gas main.  Wylie and his team placed the recovered bomb on a lorry, which was driven to Hackney Marshes, where the bomb was detonated, leaving a crater  wide.

The citation from a supplement to The London Gazette of 27 September 1940 (dated 30 September 1940) reads:

OFML. Office Furniture Modeling Language (OFML) is a standard of the IBA  Industrieverband Büro und Arbeitswelt e.V. (former BSO Verband Büro-, Sitz- und Objektmöbel e.V.), or the German Furniture Manufacturers Association. It was created in 1998 to provide a common method of describing furniture products. The standard has seen little support outside of usage by the authors and a few adaptions.

Motivations

OFML is the result of a series of requirements that could generally not be met with past solutions:
 The new requirements in the area of planning and visualization of furniture cannot be met alone by CAD-based systems. The main problems of CAD-based solutions are the enormous data size, the poor parameterizability and configurability, insufficient product logic, insufficient interactivity and complicated operation.
 A platform-independent and software manufacturer-independent data format which allows an unlimited number of software manufacturers to offer systems and solutions so that monopolizing conditions can be avoided or eliminated.
 The new data format also allows for the implementation of a series of applications that are compatible with respect to the data in spite of different orientation. In this way it is possible to achieve compatibility and, therefore, technological uniformity between manufacturer, trade, and end user systems.

Features
The OFML standard has the following features:
 consistent application of object-oriented paradigm,
 conversion of concepts of semantic modeling to match virtual objects with actual products,
 combination of geometric, visual, interactive, and semantic features of real products in a uniform and holistic data model,
 mapping of real configuration logic and parameters,
 independence of system or interface platforms, and
 independence of a concrete runtime environment.

Levels
OFML level Base. The level Base defines a table-based interface for description of hierarchical geometries in 2D and 3D.OFML level GO. The level Generic Office library extends the level Basis with functionality for interaction and behavior.OFML level Language. The level Language defines a complete programming language that may be used for the creation of arbitrary complex data and the integration of external commercial data, for instance.
