Nerikomi. is a  Japanese pottery term describing the artistic technique where multiple colors of clay are marbled or combined to create various designs. The technique can also be called , although this more commonly refers to throwing multiple colors of clay on a wheel.

History
 is a contemporary Japanese term. Marbling ceramic techniques were first found used in Egypt and China and through the Romans to the West. Early ceramics in Stoke-on-Trent use more than one colour of clay for decorative effect. In England this was referred to as agateware.

In Japan there are a few pieces from the Momoyama period (1568–1600), and Edo period (1603–1868), as well as extant pieces of , that display marbled ceramics. There was an explosion in popularity of the technique from about 1978–1995 in Japan, due probably to Aida Yusuke's advertising and to Matsui Kousei, who refers to his work as .

The term started being used in the 1970s to describe related kanji neriage. Yusuke Aida was on a television commercial for Nescafé and it seems to have entered the vocabulary at about that time when his nerikomi coffee cups were available to the first people contacting the advertisers.

It was used in the Tang dynasty in 7th-century China there are at least two Chinese characters to describe variations of this technique (one surface, one structural).

Technique
In , a design is created in such a way that it extends through a long block of clay, akin to the murrine canes of millefiori glasswork. By slicing thin slabs of the block, the design can be repeated, to either be reassembled in repetition or applied to a larger piece.

Soltam M-71. The M-71 is a 155 mm 39 caliber towed howitzer manufactured by Israeli company Soltam Systems.

Design
The weapon was based on the earlier Soltam M-68 and uses the same recoil system, breech and carriage but had a longer gun barrel (39 calibre versus 33 calibre of M-68). It is fitted with a compressed air-driven rammer to permit rapid and easy loading at all angles of elevation as well as having a rechargeable battery mounted on the right trail for auxiliary power. It can fire a  high-explosive shell up to a maximum range of  at a muzzle velocity of .

Deployment
In addition to Israel, this weapon is in service with Chile, Singapore, Thailand, Philippines, South Africa, Slovenia and Myanmar. A version of this weapon was developed to mount on a modified Centurion chassis (M-72), but this vehicle never reached production.

HŽ series 2043. Series 2043 is a diesel-electric locomotive series on Croatian Railways ().

With the electrification of magistral railway lines the need has arisen that diesel locomotives are put into service on less frequently used lines. Usually lesser axle load is allowed on a branch line and less frequented lines.

A locomotive, which was light and powerful enough was needed.

Therefore, the series 2061 was stripped down and series 2043 was created.

All six locomotives were taken out of service, the last one in 2011. With this the most weight was lost. Now, the adhesion is distributed differently.

EMD SD89MAC. The EMD SD89MAC was a  C-C diesel-electric locomotive produced by General Motors Electro-Motive Division.  Along with the SD80MAC and SD90MAC, the SD89MAC was one of the largest single-engine locomotives produced by EMD. The SD89MAC featured radial steering trucks and an isolated cab which was mounted on shock absorbers to reduce vibration. The SD89MAC used AC traction motor technology.  Like the SD90MAC, it was a hood unit fitted with a safety cab and has an enlarged radiator section, nearly the entire width of the locomotive, which makes it easy to spot. The frame of GM 92, the only SD89MAC ever built, has since been retrofitted with a different engine for Tier 4 compliance tests conducted by EMD. 

The SD89MAC was intended to be less-powerful version of the SD90MAC, and eventual successor to the SD70 series. One demonstrator was built, but generated no orders.

Jonathan F. Earle. Jonathan F.K. Earle completed his Ph.D. at the University of Florida in 1985, and joined the faculty in the Department of Agricultural & Biological Engineering in 1987. He was appointed Assistant Dean for Student Affairs at the University of Florida College of Engineering in 1992. This position was later upgraded to Associate Dean. He remained in this position until his retirement in December, 2007. He now holds the title "Associate Dean Emeritus".

In this position, he created the Engineering Student Services Center to provide advising, resources and academic support to engineering students. He is perhaps best known, though, for his dedication to increasing the retention and graduation rates of minority students in engineering disciplines. In 1993 he implemented the STEPUP program (Successful Transition through Enhanced Preparation for Undergraduate Programs), based on the Meyerhoff model. STEPUP provides an intensive 6-week residential program for selected students and includes peer mentoring, academic preparation in calculus and chemistry, as well as industry networking opportunities. In 2000 - 2001, he was responsible for the implementation of EFTP (Engineering Freshman Transition Program), which provided a nonresidential experience open to all engineering freshman, as well as the Engineering GatorTrax Math Excellence Program, which was designed to provide hands-on applications of classroom mathematics concepts to middle and high school students in the state of Florida. He also implemented the Gator Engineering Outreach Program.

In 2007 he received the National Science Foundation Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring.
  
Earle was elected to the National Executive Council of Tau Beta Pi engineering honor society in 2006, where he is currently expanding the GatorTrax model to a national level under the name MindSET.

Education
Earle received both his Masters and Doctorate (1985) from the University of Florida.

Oil megaprojects. Oil megaprojects are large oil field projects.

Summary of megaprojects
Definition of megaproject: 20,000 barrels per day (3,200 m3/d) of new liquid fuel capacity.

Megaprojects predicted for individual years

Application to oil supply forecasting

A series of project tabulations and analyses by Chris Skrebowski, editor of Petroleum Review, have presented a more pessimistic picture of future oil supply. In a 2004 report, based on an analysis of new projects over , he argued that although ample supply might be available in the near-term, after 2007 "the volumes of new production for this period are well below likely requirements."  By 2006, although "the outlook for future supply appears somewhat brighter than even six months ago", nonetheless, if "all the factors reducing new capacity come into play, markets will remain tight and prices high. Only if new capacity flows into the system rather more rapidly than of late, will there be any chance of rebuilding spare capacity and softening prices."

The smallest fields, even in aggregate, do not contribute a large fraction of the total.  For example, a relatively small number of giant and super-giant oilfields are providing almost half of the world production.

Decline rates

The most important variable is the average decline rate for Fields in Production (FIP) which is difficult to assess.

Cox-Klemin Aircraft Corporation. The Cox-Klemin Aircraft Corporation was an American aircraft manufacturer based in Long Island, New York in the 1920s.

History
It was founded by Charles Cox and Alexander Klemin (a professor at New York University) in College Point, New York. The company took over an ordnance plant in Baldwin, New York in 1924. Later that year, it partnered with Ernst Heinkel to design and build a mailplane.

In defiance of prohibition, the company christened its new Nighthawk airplane using champagne in 1925.

The company filed for bankruptcy in 1925. However, bankruptcy proceedings continued into 1926. The case was further delayed after the court could not locate company management.

Grumman would later open its first plant in the shuttered Cox-Klemin factory in 1930.

Bulk leach extractable gold. Bulk leach extractable gold, more commonly shortened to BLEG, is a geochemical sampling/analysis tool used during exploration for gold. It was developed in the early 1980s to address concerns relating to the accurately measuring fine grained gold, and dealing with problems associated with sample heterogeneity.

Analysis 
A large quantity of sample (between 2 and 5 kg) is digested or leached with cold sodium cyanide (NaCN) solution (generally 0.1% NaCN), for one to several days (depending on the assay laboratory involved). The gold is dissolved through its formation of a cyanide complex, which is concentrated through the solvent exchange process into an organic solvent and subsequently analyzed. The use of large sample weights and solvent extraction enables low detection limits, as low as 0.1 ppb. The digest is analyzed for Au (0.01 ppb), Cu (0.01 ppm), Ag (0.5 ppb), and depending on situations, for other elements. However, gold values in BLEG are lower than total assays such as those of fire assays, as it analyzes only the fine grained gold fraction and largely ignores coarser and nuggety gold.

If the need arises, a separate split of the original sample is used for pathfinder elements.

Sampling considerations 
BLEG requires the collection of large samples, generally greater than 2 kg. It is necessary to collect fine sized material – silt to clay – where the fine flakes of gold will reside. Given their shape, these fine flakes of gold do not act hydro-dynamically like heavy minerals, and will not settle in the same locations in a stream bed. Where possible, attempts should be made to sample flash flood sites (where finer material concentrates) – overbank deposits.

Vs sieving 
BLEG is essentially a chemical sieve, designed to focus on the fine grained gold fraction. While many exploration geologists attest to the value of BLEG, some question its value compared to analyzing a simple sieved-out fine grained fraction. BLEG has been tried and tested over 20 years, applied successfully in different climatic settings, provides robust, excellent repeatability of results and has had an important role in discovery of massive Au deposits. However, some comparisons show that fine-grained sieved samples (<75 μm) show comparable results to BLEG, making the more complex process potentially unnecessary. With the exception of BLEGs applicability over a wider range of climatic conditions, the superiority of one method over the other is, at this point, still largely determined by personal preference.

Urgent computing. Urgent computing is prioritized and immediate access on supercomputers and grids for emergency computations such as severe weather prediction during matters of immediate concern.

Applications that provide decision makers with information during critical emergencies cannot waste time waiting in job queues and need access to computational resources  as soon as possible. Systems for urgent computing commonly use dedicated resources to ensure immediate and dedicated access to urgent computations. However, recent studies have shown the possibility of using shared resources to make urgent computing more economical.

Joseph Chaley. Joseph Chaley (1795 – April 15, 1861) was a French civil engineer and a pioneer designer of suspension bridges in the 19th century. He was a medical officer in the army before becoming a bridge designer.

Chaley pioneered the construction of suspension bridge cables by bringing together individual wire strands in mid-air, a technique later known as aerial spinning. Previously, the entire cable had been bound together before lifting into place, but Chaley's system, inspired by the ideas of Louis Vicat, allowed considerably longer cables to be erected at less cost.

He built the Grand Pont Suspendu at Fribourg in 1834, a world record-breaking span of 273m, only overtaken 16 years later by Charles Ellet Jr.'s 308m span Wheeling Suspension Bridge. Chaley had previously worked with Marc Seguin's brother Jules on the Tarascon-Beaucaire Bridge (1828) and also the Chazey-sur-Ain Bridge (1829).

Chaley first presented a proposal for the Grand Pont Suspendu in February 1830, and was awarded the contract in June of that year. His estimated cost of less than 300,000 florins was well below other competitors, including Guillaume Henri Dufour. Chaley's bridge was supported on four main cables (two per side), each consisting of 1056 wires each 3.08mm in diameter. It carried 2000 people on its opening day. It was replaced in 1923 by a reinforced concrete arch bridge.

Chaley's other suspension bridges include the 227m Pont du Gottéron (1840); and a 64m span at Collomby in Valais (1840). He collaborated with Bordillon on the Basse-Chaîne Bridge at Angers, completed in 1839. This bridge collapsed in 1850 killing 226 soldiers, a major setback to suspension bridge construction in France and beyond.

His only bridge still in existence is the 121m suspension bridge at Corbières (1837).

HMS Lion (1847). HMS Lion was a 80-gun second rate  ship of the line built for the Royal Navy in the 1840s. She was fitted with steam propulsion in 1858–1859. In 1871 Lion was converted into a training ship at HM Dockyard, Devonport. The ship was sold for scrap in 1905.

Description
The Vanguard class was designed by Sir William Symonds, Surveyor of the Navy, with each ship built with a slightly different hull shape to evaluate their speed and handling characteristics. Lion had a length at the gundeck of  and  at the keel. She had a beam of , a draught of  and a depth of hold of . The ship's tonnage was 2,589  tons burthen. The Vanguards had a wartime crew of 720 officers and ratings.

The Vanguard class ships of the line were armed with twenty 32-pounder (56 cwt) cannon and two 68-pounder carronades on her lower gundeck, twenty-eight 32-pounder (50 cwt) cannon and another pair of 68-pounder carronades on the upper gundeck. On her quarterdeck were fourteen 32-pounder (42 cwt) cannon and on the forecastle deck were eight more 32-pounder (42 cwt) cannon.

Modifications
When Lion was ordered to be modified for steam propulsion in 1856, she was fitted with a two-cylinder horizontal trunk steam engine of 400 nominal horsepower that drove a single propeller shaft. On trials the engine produced  which gave the ship a speed of .

Construction and career
Lion was ordered from Pembroke Dockyard on 18 March 1840 and laid down the following July. She was launched on 29 July 1847 and completed on 26 September. The ship was not fitted out and Lion was placed in ordinary. Her construction cost £59,113. Between February 1858 and May 1859, she was fitted with steam propulsion.

Lion was sold for scrap on 11 July 1905.

Electrohydrogenesis. Electrohydrogenesis or biocatalyzed electrolysis is the name given to a process for generating hydrogen gas from organic matter being decomposed by bacteria.  This process uses a modified fuel cell to contain the organic matter and water.  A small amount, 0.2–0.8 V of electricity is used, the original article reports an overall energy efficiency of 288% can be achieved (this is computed relative to the amount of electricity used, waste heat lowers the overall efficiency).  This work was reported by Cheng and Logan.

Outline of computer engineering. The following outline is provided as an overview of and topical guide to computer engineering:

Computer engineering – discipline that integrates several fields of electrical engineering and computer science required to  develop computer hardware and software. Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware–software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work, but also how they integrate into the larger picture.
