Fuel Manufacturing Pilot Plant. The Fuel Manufacturing Pilot Plant (FMPP), also known as Fuel Element Fabrication Plant, is a nuclear fuel fabrication facility supplied by the Argentine company INVAP in 1998. The FMPP is considered a Material Testing Reactor (MTR)-type fuel element facility, that produces the fuel elements required for the research reactor ETRR-2.

The plant uses enriched uranium hexafluoride (UF6, 19.75% U235) as a raw material which is processed to produce the final MTR-type fuel elements.

The FMPP is owned and operated by the Egyptian Atomic Energy Authority (AEA) at the Nuclear Research Center in Inshas, 60 kilometers northeast of Cairo.

History 
The Egyptian Atomic Energy Authority (AEA) contracted with the Argentine company INVAP to construct the Fuel Manufacturing Pilot Plant (FMPP) at the Nuclear Research Center in Inshas with the construction works began in 1995, with pre-operational tests in 1997, and a final complete production in December 1998.

The National Atomic Energy Commission (CNEA) was responsible for the technology transfer and Egyptian staff training during the commissioning and installation of FMPP by personnel from the (Uranium Powder Manufacturing Plant) and the (Research Reactors Fuel Elements Plant) were both plants in CNEA served as a FMPP design basis. During the setup of the facility a fuel element was manufactured using natural uranium firstly and then another one using 20% enriched uranium.

Overview 
The Fuel Manufacturing Pilot Plant (FMPP) is considered the most sophisticated fuel cycle facility in Egypt, which is a semi-pilot facility produces the fuel elements required by the Egyptian second research reactor ETRR-2.

FMPP has a production design capacity of 40 fuel element per year, with a total uranium content of 2054 g each and 220 days of estimated annual working time in two shifts with 8 hours each, which is sufficient to ensure continuous ETRR-2 reactor operation.

FMPP is under IAEA safeguards.

Octamethylcyclotetrasiloxane. Octamethylcyclotetrasiloxane, also called D4, is an organosilicon compound and one of a number of cyclic siloxanes (cyclomethicones). It is a colorless viscous liquid with a high boiling point. It has historically been used on a large scale in personal care products including cosmetics, hair conditioners and emollients (moisturising creams), Global production in 1993 was 136,000 tons, however it is now facing significant pressure from regulators. It is a substance of very high concern In the EU, where it was classified as a PBT and effectively banned in personal care products in 2018. The US EPA began reevaluating its risks in 2020. Replacements include branched-chain alkanes (isoparaffins).

Production and polymerization
Commercially D4 is produced from dimethyldichlorosilane. Hydrolysis of the dichloride produces a mixture of cyclic dimethylsiloxanes and polydimethylsiloxane. From this mixture, the cyclic siloxanes including D4 can be removed by distillation. In the presence of a strong base such as KOH, the polymer/ring mixture is equilibrated, allowing complete conversion to the more volatile cyclic siloxanes:

D4 and D5 are also precursors to the polymer. The catalyst is again KOH.

Safety and environmental considerations 

D4 is of low acute toxicity. The LC50 for a single four hour inhalation exposure in rats is 36 mg/L. The oral LD50 in rats is above 4800 mg/kg and the dermal LD50in rats is above 2400 mg/kg.

As the smallest cyclic dimethylsiloxane that does not experience considerable ring strain, D4 is one of the most abundant siloxanes in the environment, e.g. in landfill gases. D4 and D5 have attracted attention because they are pervasive. Cyclic siloxanes can be detected in some species of aquatic life. An independent, peer-reviewed study in the US found "negligible risk from D4 to organisms" while a scientific assessment by the Australian government stated, "the direct risks to aquatic life from exposure to these chemicals at expected surface water concentrations are not likely to be significant."

In the European Union, D4 was characterized as a substance of very high concern (SVHC) due to its PBT and vPvB properties and was thus included in the candidate list for authorisation. D4 shall not be placed on the market in wash-off cosmetic products in a concentration equal to or greater than 0.1% by weight of either substance, after 31 January 2020. Conversely, a detailed review and analysis of the science by the State of Washington in 2017 led to the removal of D4 from their CHCC listing. That decision prompted the State of Oregon to follow suit in 2018.

Robot Roller-Derby Disco Dodgeball. Robot Roller-Derby Disco Dodgeball is an arcade arena dodgeball video game developed by Erik Asmussen. The game was released on 19 February 2015 for Windows, Mac, and Linux.

Gameplay
In the game, players control a robot with one wheel from a first-person point-of-view. They can throw balls at other players to knock them out or score points and catch them to eliminate the thrower; more points can be earned through creative or skillful hits such as ricocheting the ball. Players can also deflect balls with the one they are currently holding. Movement in the game is dependent on the player's momentum, with travel continuing in a direction even if the player isn't holding a directional key.

The game has a Tron-like visual theme and a disco-themed soundtrack to match. It also has cosmetic items available for customizing the look of the player's robot. These items are tradeable for real currency on the Steam Workshop. The game has a number of different single and multiplayer modes where players can climb up the leaderboards while playing.

Development
Robot Roller-Derby Disco Dodgeball was developed by Erik Asmussen starting in July 2013. He began with the game's movement mechanics, saying that he enjoyed playing with the skating-like movement before any other aspects of the game had been developed.

The game was in a beta phase of development on Steam Early Access for a time before being released fully on 19 February 2015. Asmussen said that the Early Access period was important for the game's development, as he received feedback from players tweaking and testing the game's settings. He plans to include more features in the future, including a level editor and local multiplayer.

Reception
Josiah Renaudin of GameSpot gave the game a rating of 6/10, saying it was fun to play and commenting positively on the visual style as well as the number of game modes available. However, he said that he felt the game didn't provide much incentive for continuing to play and that it was hard to correctly predict a throw's trajectory. Thomas Ella of Hardcore Gamer rated the game 4/5, describing it as "one of the best, most fun, well-crafted multiplayer games available right now" but expressed disappointment at the low number of online players.

Parascender Technologies. Parascender Technologies, Inc. (usually just referred to as Parascender) was an American aircraft manufacturer based in Kissimmee, Florida, founded by RB Brady and Teri Brady in 1989. The company specialized in the design and manufacture of powered parachutes in the form of kits for amateur construction.

The company seems to have gone out of business in September 2004.

The company produced a line of powered parachutes, including the single place Parascender I introduced in 1989, the two seat Parascender II introduced in 1990 and the Parascender Para-Ag Single seat agricultural application powered parachute.

Controversy
The company's business practices were controversial. In December 2002 the Aero News Network (ANN) reported that the company had been the subject of "a number of lawsuits, criminal complaints, and a great many civil complaints to better business bureaus and State's Attorneys General", described the founder as a "convicted felon" and concluded "ANN strongly recommends that Parascender Technologies be avoided (like a cliche, or like the plague…) as a candidate for flight training, PPC dealership agreements, powered parachute equipment, or PPC airframe purchases. We simply have too extensive and persuasive a record of this company's false statements, frauds and other non-performance to remotely believe that there is anything about them that can be recommended."

Henry Ernest Milner. Henry Ernest Milner (18 April 1845 – 10 March 1906) was an English civil engineer and landscape architect.

Personal life
He was the son of landscape architect Edward Milner and his wife, Elizabeth Mary Kelly, who had eleven children, of whom Henry Ernest was the eldest, born in Liverpool on 18 April 1845.  He was educated by private tutor in Germany and France.  In 1869 he married Mary Dickey, daughter of Canadian Senator Robert B. Dickey.  The couple had two children: a son, Barry Ernest, and a daughter, Winifred; she married Edward White who was trained in, and ultimately took over, his father-in-law's landscape architecture practice.

Career
Milner's working career started in London during 1862 when he was employed by Morton Peto.  He remained in London until 1864 when he travelled to Russia on an assignment to carry out work on railways as an assistant engineer.  During 1868 he moved to Nova Scotia, where he was the resident engineer on the Windsor and Annapolis Railway.  He worked with his father's company after returning to England, becoming a full partner in 1881.  Among the commissions he undertook were: Ashtead Park; Victoria Park in Glossop; and Overtoun Bridge in West Dunbartonshire for Lord Overtoun.  He was elected to membership of the Institution of Civil Engineers in 1878.  Working abroad again by 1885, he was commissioned by Count Tasziló Festetics to redesign the landscaping around the recently expanded Festetics Palace in Keszthely, Hungary.  He returned several years later, in 1893, to do further work.  Around 1895 Milner was trading from a business address in Westminster, London.

Following the 1890 publication of his book, The Art and Practice of Landscape Gardening, Milner was hired to plan several notable projects.  These included the designs for the 250 acre grounds surrounding Sir Edward Watkin's tower at Wembley Park; although the gardens, which incorporated architectural features like a fountain, were completed, financial constraints and problems with the foundations of the tower meant only the first level was built and that was knocked down in 1907. He was also commissioned to design the gardens at Friar Park for Sir Frank Crisp and the parterre, Pleasure Gardens and Old World Garden at Gatton Park under instructions from Sir Jeremiah Colman.

In 1897 the Royal Horticultural Society initiated an award for British horticulturists, styled as the Victoria Medal of Honour, to be given to people the officials of the society "considered deserving of special honour".  Milner is listed as one of the first sixty individuals awarded it.  Two years later, in 1899, he was presented with the Swedish North Star award for several contracts he had undertaken in the Royal Gardens.

Death and legacy
Milner died at his home, 119 Gipsy Hill, Norwood, on 10 March 1906.  He is buried in Darley.
