Donald J. Metz. Donald J. Metz (May 18, 1924 – May 9, 1999) was an American nuclear engineer at Brookhaven National Laboratory. Metz's research focused on the effects of radiation on polymerization.

Early life and education
Metz began his undergraduate education at St. Francis College in 1941, yet it was interrupted by World War II. For three years he was in the infantry in Europe, yet upon his return he once again enrolled in St. Francis College and completed his B.S. in chemistry in 1947. Metz went on to conduct graduate work at the Polytechnic Institute of Brooklyn and was granted an M.S. in 1949, and a Ph.D. in physical chemistry in 1955.

Career

Brookhaven National Laboratory
In 1954, Metz joined the staff at Brookhaven National Laboratory in the nuclear engineering department. While there he was appointed supervisor of radiation research in the radiation division. By 1972, Metz headed the chemical sciences division in the department of applied sciences. To pursue his interest in science education Dr. Metz relinquished his position in 1985 to become the head of the Office of Educational Programs (OEP). In 1993, Metz retired after having expanded the OEP, oversaw the creation of a new Science Learning Center, and started at Brookhaven, what would become a nationwide educators program at D.O.E. laboratory's.

Metz also gave two laboratory-wide lectures while at BNL; the 70th Brookhaven Lecture on Radiation and Organic Liquids and the 169th Brookhaven Lecture on Energy Future: A Prime for Secondary School Teachers.

St. Francis College
From 1947 to 1976, Metz was a professor of chemistry and physics at St. Francis College. During his tenure, Metz was known to be a devoted professor, so although he worked full-time at Brookhaven National Laboratory, he would teach classes on Saturdays.

Philanthropy
A few years after Metz retired in 1993, Donald and Dorothy Metz donated $100,000 to establish a scholarship program for the disabled children of Brookhaven lab employees. Named the Gorman-Metz scholarship in memory of Mr. and Mrs. Metz's parents, the award was given for the first time in March 1997. The awardees have been chosen by the National Center for Disability Services, and the scholarship has been administered by Brookhaven's Diversity Office.

Awards

Charlotte Aircraft Corporation. Charlotte Aircraft Corporation is a company headquartered in Charlotte, North Carolina which deals in used aircraft and aircraft parts.  The company was founded by Jenks Caldwell Sr. in 1953.  Today the company is run by his son Jenks Caldwell Jr.  The company's main business is reselling refurbished aircraft parts which it acquires by purchasing used aircraft and stripping them of their useful parts, storing them until required, and re-furbishing them before sale to the customer.

The company also has a history of engine modification.  In the 1950s the company refitted Wright R-2600 engines for the DC-4.

Locations 
 Headquarters:  Delta Airbase, Charlotte, North Carolina (): Sometime in the late 1950s the company acquired Delta Airbase, an airfield located off WT Harris Blvd in Charlotte, NC and moved it operations there from Charlotte Douglas Airport.  Delta Airbase was created by some people from the Mississippi Delta area who moved to Charlotte to establish an airfield and operation to train pilots during World War II (hence the name Delta Airbase). In the 1960s the company purchased a large number of ex-Eastern Airlines DC-6s & DC-7s.  These were flown into Delta Airbase and parted out. Sometime in the past 20 years the airstrip was shortened and some of the land was used to develop an apartment complex.
 Laurinburg-Maxton Airport ():  The company has a sizable operation at Laurinburg-Maxtion Airport where it flies in aircraft and reduces them to parts.  Aircraft such as 747s, 737s, 727s, DC-10 and DC-9s are visible from perimeter roads in various stages of stripping of usable parts.

Museum and Film aircraft

In 2006, the forward fuselage of the first 747 purchased by Northwest Airlines was removed from the airplane at Maxton and taken and installed in the National Air and Space Museum in Washington, D.C.

A Boeing 727 aircraft was trucked from Maxton to Massachusetts for use in the Tom Cruise movie Knight and Day.

253 Squadron (Israel). 253 Squadron of the Israeli Air Force, also known as the Negev Squadron, is an F-16I fighter squadron based at Ramon Airbase.

History 
On 27 July 1976 the squadron was founded at Hatzor Airbase and were assigned IAI Neshers.

In 4 June 1978, the 253 Squadron was told to retrain on the Dassault Mirage III aircraft. Following the signage of the Egypt–Israel peace treaty, Israeli forces withdrew and had to abandon established bases in the area. The squadron's Mirages were relocated to a reserve squadron, with the 253 Squadron awaiting conversion to the F-16B Netz, later becoming the IDF's third F-16B squadron.

On October 1981, he squadron deployed to Ramat David Airbase, before being transferred to Ramon Airbase in early 1982.

The squadron's aircraft were equipped with guided bombs beginning in 1994. The bombs saw operational use on 3 August 1995 during Operation Iron Eagle, with two of these guided bombs striking an observation tower manned by insurgents.

The squadron also participated in the Second Lebanon War.

In March 2018, Israel's government confirmed that 253 Squadron, along with 69 and 119 Squadrons, took part and successfully completed Operation Orchard on 6 September 2007, destroying the nuclear installations of Syria constructed with the help of North Korea.

Telepointer. Telepointer is a neck-worn gestural interface system developed by MIT Media Lab student Steve Mann in 1998. Mann originally referred to the device as "Synthetic Synesthesia of the Sixth Sense". In the 1990s and early 2000s Mann used this project as a teaching example at the University of Toronto.

Aremac projector

Mann developed a laser-based infinite depth-of-focus projector, called an "aremac", to project onto any 3D surface without focus adjustment The projector originally displayed vector graphics rather than raster graphics. A raster graphics version based on a miniature wearable micromirror projector was developed in 2001, which could project onto the wearer's hands, other objects, or the floor or ground allowing it to work with both hand or foot gestures.

Takanori Okoshi. Takanori Okoshi (大越孝敬; born September 16, 1932) is a noted Japanese professor of electrical engineering, now retired, and an amateur composer of over 30 pieces of chamber music for quartet or sextet.

Okoshi was born in Tokyo, where his father was an engineering professor at the University of Tokyo. In his school days, he made radio sets and motors, and subsequently received a bachelor's degree in electrical engineering from the University of Tokyo in 1955, specializing in electronics and communications. His bachelor's thesis work, "The Generation of Millimeter Waves by Harmonic Generators" was published in the journal of the Institute of Electrical Communications Engineers of Japan. His then received both masters' and doctoral degrees from the University of Tokyo, working on electron guns under the supervision of Professor Okamura, later President of the Tokyo Denki University.

Immediately after receiving his PhD, Okoshi was appointed lecturer at the University of Tokyo where he remained until retirement. As professor, he was a renowned expert in optoelectronics and holography, planar circuits, and optical fiber communication. From April 1963 through the fall of 1964, he visited Bell Labs at the invitation of Michiyuki "Mickey" Uenohara, where he worked on electron guns but also became acquainted with lasers. After his return to Tokyo, he started work on a novel idea for the soft landing collector tube, which he first described publicly in the 1970 International Electron Devices Meeting in Washington DC. From about 1967, he began theoretical work on three-dimensional imaging, and by the early 1970s about half the activities in his laboratories concerned optoelectronics. A notable invention from those years was wide view projection holography; he also wrote several textbooks in the field. From about 1980 onwards, his interest shifted to planar circuits, optical fiber communications, and photon counting.

After his retirement from the University of Tokyo in 1993, Okoshi was named director of the Japanese government's National Institute for Advanced Interdisciplinary Research (NAIR).

Okoshi has served as president of the Institute of Television Engineers and the IEICE (The Institute of Electronics, Information and Communication Engineers), and vice president of the Engineering Academy of Japan and the International Union of Radio Science (URSI). He has been awarded the 1993 Japan Academy Prize for "Research on Coherent Optical Fiber Communications", 1994 C&C Prize, Fujiwara Prize, and 1988 IEEE Morris N. Liebmann Memorial Award "for leadership in and pioneering contributions to coherent optical fiber communications."

China Railways DJ1. The China Railways DJ1 is a high power mainline electric freight locomotive built as a double locomotive unit of two nominally independent single cab units.

History and design
The locomotives are based on a technology transfer agreement between Siemens and Zhuzou Electric locomotive works (ZELW). The first three locomotives were built by Siemens in Austria, and the remaining 17 were built in China.

The electrical components in the locomotive are based upon Siemens' EuroSprinter design (second generation using water-cooled GTO inverters). The traction motors are asynchronous AC type, and are nose suspended on the axle, regenerative electric braking is possible with a braking force of approximately , and an electric braking power of , overall efficiency of the machine is more than 85%.

3 of the units were manufactured by Siemens in Austria, the remaining 17 in China; the first locomotive was produced in 2001. The first china manufactured unit was produced in 2002. Production of the locomotive ended in 2003.

The locomotives were used to haul coal trains on the Daqin line.

As more powerful locomotive models HXD1 and HXD2 entered Daqin line since 2006, the 20 DJ1s were allocated to Xi'an Railway Bureau to haul freight trains running between Baoji and Qinling.

Ford Model 15-P. The Ford Model 15-P flying wing was the last aircraft developed by the Stout Metal Airplane Division of the Ford Motor Company. After several flights resulting in a crash, the program was halted. Ford eventually re-entered the aviation market producing Consolidated B-24 Liberators under license from Consolidated Aircraft.

Development
A press release in Jan 1936 said that Ford was designing behind closed doors a new "flivver" using its new V-8 engine.

Design
The Model 15-P was a two-passenger "flying wing" or tailless design. It featured a rear-mounted Ford V-8 driving a tractor propeller with a driveshaft The fuselage was steel tube with an aluminum covering and the wings were fabric-covered. The landing gear was fully faired with large landing lights mounted in the fairings.

Operational history
Several test flights were made by test pilot Harry Russell, but after an accident the aircraft was put in storage. The aircraft was licensed by the Federal Bureau of Air Commerce in 1936, the same year Ford closed its aircraft division.  The remains of the 15P were used to create a prototype autogyro, but all trace of the 15P disappeared when the autogyro was scrapped.

Methylcyclopentane. Methylcyclopentane is an organic compound with the chemical formula CH3C5H9. It is a colourless, flammable liquid with a faint odor. It is a component of the naphthene fraction of petroleum usually obtained as a mixture with cyclohexane. It is mainly converted in naphthene reformers to benzene.

As of early 1990s, it was present in American and European gasoline in small amounts, and by 2011 its share in US gasoline varied between 1 and 3%. It has a research octane number of 103 and motor octane number of 95.

The C6 core of methylcyclopentane is not perfectly planar and can pucker to alleviate stress in its structure.

History
Methylcyclopentane was first synthesized in 1888 by  and W. H. Perkin Jr. by a Wurtz reaction of sodium and 1,5-dibromohexane. They named it methylpentamethylene since the modern nomenclature wasn't developed until 1892 Geneva Rules.

In 1895, Nikolai Kischner discovered that methylcyclopentane was the reaction product of hydrogenation of benzene using hydriodic acid. Prior to that, several chemists (such as Marcellin Berthelot in 1867, and Adolf von Baeyer in 1870) had tried and failed to synthesize cyclohexane using this method.

Egyptian frigate Ibrahim. Ibrahim was a steam frigate built for the Egyptian Navy, and launched on November 30, 1868 at La Seyne.  The ship was fully rigged and had an iron hull.  At the time Egypt had also ordered several armored ironclads, the Nijmi Shevket class and the Lutfi Djelil class each of two ships.  Although intended for the Egyptian Navy, these ironclads were delivered to the Ottoman Navy in 1869. In this period Egypt was nominally a province of the Ottoman Empire but was run autonomously (with increasing influence of French and British interests culminating in a British takeover in 1882).  Egypt was apparently allowed to keep the large frigate Ibrahim, which with the smaller frigate Mehemet Ali and one corvette the Sakka formed the Egyptian steam navy until 1890, when the Ibrahim was scrapped and the other two ships had their machinery removed to become stationary guard ships at Alexandria and Port Said. Egypt also had a large iron yacht, the Mahroussa which survives in rebuilt form to the present day.

An alternate contemporary English spelling for the ship's name was Ibraichneih.
