Amicite. Amicite is a silicate mineral of the zeolite family. It has a general formula of K2Na2Al4Si4O16·5(H2O). Amicite was described in 1979 from specimens obtained at the Höwenegg quarry in Immendingen, Hegau, in the German state of Baden-Württemberg, which is consequently its type locality. The name is  in honor of Giovanni Battista Amici (1786–1863) a botanist, physicist, optician, and inventor of microscope optical elements.

Structure and optical properties
Amicite is monoclinic, so the crystallography has three axes of unequal length and the angles between two of the axes are 90 degrees and one is less than 90. Amicite is also pseudotetragonal with a = 10.23, b = 10.43, c = 9.88, and d = 89, and belongs to the space group I2.It appears as small colorless crystals, formed by the rhombic prisms {110} and {001}, combined in such a way that the crystal appears to be a dipyramid.

Amicite is classified as biaxial anisotropic so the velocity of light varies depending on direction through the mineral, as well as showing double refraction. The index of refraction is the geometric ratio of the angle of light entering the crystal (angle of incidence) over the angle the light is bent when it enters the crystal (angle of refraction). The index of refraction can be defined mathematically as n=velocity of light in a vacuum/velocity of light in the mineral. Amicite has three indices of refraction na = 1.485, nb = 1.490, nc = 1.494. A minerals birefringence is defined as the difference between the highest and lowest index of refraction, amicite's birefringence is 0.009.

Amicite is a zeolite mineral, the commercial uses of zeolites are a function its three distinct properties: absorption, ion exchange, and catalysis. Zeolites are also known for their ability to absorb and lose water without any effect on its crystal structure.

Occurrence 
Amicite is a very rare mineral, known only in four locations in the world, the type locality, the Vostochnyi and Kirovskii mines in the Chibiny massif, Murmansk region (Russia), where the largest known crystals come from, and also the quarry from Las Urracas, on the El Arzollar volcano, Campo de Calatrava (Ciudad Real). In addition to being poorly distributed, it is very scarce in the four locations mentioned.

Sacrofanite. Sacrofanite is a rare silicate mineral that has the general formula of .  It was approved as a mineral by the International Mineralogical Association in 1980. Its name comes from the Sacrofano Caldera in the Monti Sabatini from which it was discovered in Latium, Italy.

Structure and optical properties
It has a hexagonal crystal system, meaning crystallographically it has three horizontal axes of equal length that make an angle of 120° with their positive ends, with a long vertical axis running perpendicular to them. The mineral is anisotropic, meaning the velocity of light through a mineral will vary depending on the direction that the light is going. It has a moderate relief ranging from 1.486 to 1.505. It has a birefringence of 0.019, with birefringence being the decomposition of a light ray into two different rays when light hits a mineral. Sacrofanite is uniaxial negative, meaning it has one optic axis and that the index of refraction for the ordinary ray is greater than the index of refraction for the extraordinary ray.

Occurrence
Sacrofanite is only found in the Sacrofano Caldera in Italy, yet it represents one of many new minerals found in Italian volcanoes. It can be found on display in The Mineralogical Museum at the University of Rome.

It occurs as a crystal coating within a vug in a rock ejected from the volcano. Other minerals occurring in the rock include sanidine, andradite, fassaite, leucite and hauyne.

Redistribution (chemistry). In chemistry, redistribution usually refers to the exchange of anionic ligands bonded to metal and metalloid centers. The conversion does not involve redox, in contrast to disproportionation reactions.  Some useful redistribution reactions are conducted at higher temperatures; upon cooling the mixture, the product mixture is kinetically frozen and the individual products can be separated.  In cases where redistribution is rapid at mild temperatures, the reaction is less useful synthetically but still important mechanistically.

Examples
Redistribution reactions are exhibited by methylboranes.  Thus monomethyldiborane rapidly converts at room temperature to diborane and trimethylborane:
6 MeB2H5  →  5 B2H6  +  2 Me3B

Useful redistribution reactions are found in organoaluminium, organoboron, and organosilicon chemistry.
 BCl3  +  2 B(C2H5)3  →   3 BCl(C2H5)2
In another example, tetramethylsilane is an undesirable product of the industrially important direct process, but it can be converted (recycled) into more useful products by redistribution with silicon tetrachloride:
 SiMe4  +  SiCl4  →   2 SiMe2Cl2
In organotin chemistry, the mixed alkyl tin chlorides are produced by redistribution, a reaction called the Kocheshkov comproportionation:
 3 SnBu4  +  SnCl4  →   4 SnBu3Cl

Many metal halides undergo redistribution reactions, usually to afford nearly statistical mixtures of products.  For example, titanium tetrachloride and titanium tetrabromide redistribute their halide ligands, one of many reactions in this conversion is shown:
 TiCl4  +  TiBr4  →   2 TiBr2Cl2

Solar power in Greece. Solar power in Greece has been driven by a combination of government incentives and equipment cost reductions. The installation boom started in the late 2000s with feed-in tariffs has evolved into a market featuring auctions, power purchase agreements, and self-generation. The country's relatively high level of solar insolation is an advantage boosting the effectiveness of solar panels; within Europe, Greece receives 50% more solar irradiation than Germany.

In 2022, solar power accounted for 12.6% of total electricity generation in Greece, up from 0.3% in 2010 and less than 0.1% in 2000. The national government's 2023 National Energy & Climate Plan anticipates solar PV capacity rising from 4.8 GW in 2022 to 14.1 GW in 2030, and 34.5 GW in 2050.

History 

Broad development of solar power in Greece started in the 2000s, with installations of photovoltaic systems skyrocketing from 2009 because of the appealing feed-in tariffs introduced and the corresponding regulations for domestic applications of rooftop solar PV. However, funding the FITs created an unacceptable deficit of more than €500 million in the Greek "Operator of Electricity Market" RES fund. To reduce that deficit, new regulations were introduced in August 2012 including retrospective feed-in tariffs reduction, with further reductions over time. These measures enabled the deficit to be erased by 2017.

Auctions have replaced FITs and after stagnating since 2013, as of 2019 Greece was again installing hundreds of MWp per year.

By April 2015, the total installed photovoltaic capacity in Greece had reached 2,442.6 MWp from which 350.5 MWp were installed on rooftops and the rest were ground mounted.  Greece ranks 5th worldwide with regard to per capita installed PV capacity.

Future developments 
Two new photovoltaic parks are currently (August 2024) under construction in Western Macedonia with a total capacity of 1,000MW. This new energy project is carried out by Greece's Public Power Corporation in a joint venture with RWE Renewables Europe & Australia. Both of these parks are expected to commence operations in 2025. In addition, a new photovoltaic park in Thessaly of a total capacity of 390MW is under design (as of August 2024)

SkyRider (seat). SkyRider is an airliner saddle seat, a type of airplane seat shaped similar to a horse saddle. It was designed by the Italian firm Aviointeriors and reduces economy-class seating spacing (seat pitch) from an average of 32- to 30-inches, to 23-inches (58cm), a 25% decrease. The creator describes it as for use for ultra-high density seating configurations, allowing up to 40% increase in passenger capacity.

The seat was designed to reduce ticket prices and increase profits. It is for use on flights less than 3-hours in duration. The company notes that cowboys ride in similar style seats for more than 8-hours a day in comfort. The seat requires passengers to be seated partially upright, with their weight taken up by their legs.  The seat does not recline, and leaves the occupant's knees in contact with the seat in front of them.  The seat still contains a fold-down tray, and back of seat pocket, both for storage of carry-on items. The design was unveiled at the 2010 Aircraft Interiors Expo Americas on 13 September 2010, in Long Beach, California, US.

The design is superficially similar to the vertical seat design proposed by Ryanair. This stand-up seat design was met with initial skepticism by the safety and licensing authority, the European Aviation Safety Agency and the UK Civil Aviation Authority, and has not yet been licensed for use. However, the SkyRider is not expected to meet with as much regulatory resistance as the RyanAir seat.

The SkyRider seat is not currently approved by the FAA for use in the USA.

Oki Kibatarō. was a Japanese businessman and telecommunications engineer formerly employed at a Japanese Ministry of Industry (Kōbushō) factory. In 1877, only a year after Alexander Graham Bell's invention, Kōbushō had started an effort to make telephone receivers by reverse engineering and Oki was in the team that came up with the first prototype.
In January 1881, convinced that the nation was about to enter the age of communications, Oki founded Meikōsha, which was later renamed Oki Electric Industry.  The company manufactured the first telephones in Japan in 1881, only five years after the device was invented by Bell.

3D Space Wars. 3D Space Wars is a space combat video game written by Steve Turner for the ZX Spectrum and published by Hewson Consultants in 1983. It is both the first game written by Turner and the first in the Seiddab Trilogy.

Gameplay
3D Space Wars is a shoot 'em up in which the player has taken command of the world's last fighter-killer spacecraft and must prevent the destruction of civilization by the Seiddab. The game begins with the enemy massed in front of the player and attacking. The player has a cockpit view, and the ship instruments are below the viewscreen, including fuel, speed, and a galaxy map showing the Seiddab positions. Twin lasers fire perspective beams which meet in the center of the crosshairs. There are refueling points in space which the player will need to locate. Each successive wave of attackers is more destructive than the last.

The display is in black and white. Each attack wave consists of 24 aliens, and the player has only two opportunities to refuel during each wave. Speed can be adjusted to one of eight settings, which affects maneuverability, aiming weapons, and how often the ship is hit.

Development and release
Steve Turner wrote 3D Space Wars and it took about five months to develop, and this was his first game. 3D Space-Wars was released in 1983 by Hewson Consultants.

Reception
Crash gave the game an overall rating of 68% and said: "A lot of playing appeal but I didn't think there was quite enough going on in the end to make it totally addictive to play".

Personal Computer Games said: "3D Space Wars is definitely one of the better shoot-'em up games on the Dragon. The sound isn't too bad, and the graphics give a convincing impression of deep-space duelling. A worthwhile romp through the universe for those with time (and Seiddabs) to kill".

John Scriven for Dragon User wrote: "Although the combined forces of the baddies, oops, Sieddab raiders, is always more than mortal man can face, Hewson Consultants have produced an excellent game that forces you to send the rest of the family away while you turn up the tv volume and lose yourself in inter-galactic battles. Definitely my favourite game of the month".

Your Computer gave the game 3 stars and called it "an excellent Dragon game [...] Once again, there is some very good stuff around for the Dragon".

Games Computing said: "Overall, it was a well-written game but I am a bit tired of "shoot 'em up" games. I became bored usually after I had scored 120 but to the space-invader game fanatic it is a good game".

Babefphite. Babefphite is a rare phosphate mineral with the general formula BaBe(PO4)(F,OH). The name is given for its composition (Ba meaning barium, Be meaning beryllium, F meaning fluorine, and P for phosphorus).

Crystallography
Babefphite is tetragonal, which means crystallographically, it contains two horizontal and interchangeable equal axes (a1 and 2) and a longitudinal axis (c). It belongs to the 4/m 2/m 2/m point group; meaning it has four horizontal axes of twofold symmetry, two of which coincide with the crystallographic axes (a1) and (a2) and the remaining two at 45° to the (a1) and (a2).

Optical properties 
Babefphite is an anisotropic mineral meaning that the velocity of light passing through it will vary depending on the direction of travel. When measured against Canada Balsam it will display moderate positive relief. Relief is an optical property that relates the index of refraction of a mineral versus the index of refraction of another material. Positive relief denotes light being bent toward the mineral. Negative relief means the light is bent toward the mounting material. In the case of optical mineralogy, this other material is most often whatever material is used to mount the mineral in question in thin section. Based on the white color of babefphite in hand sample it is likely that it appears clear in thin section under plane polarized light. Due to its anisotropic nature, it has the possibility of displaying very weak pleochroism under the same conditions. Pleochroism is defined as a change of color, on rotation, of plane light. It occurs when the extraordinary and ordinary rays of light are absorbed differently, thereby displaying different colors. The wider the difference in the rays the more dramatic the color change. Babefphite is also weakly birefringent. Birefringence is an optical property that is determined by the direction that light passes through a mineral.

Occurrence
Babefphite was first described in 1966 for an occurrence at the Aunik fluorite-rare metals deposit, Buryatia, Eastern-Siberian Region, Russia. It has also been reported from the Rožná pegmatite in the Vysočina Region, Moravia, Czech Republic.

In the Siberian occurrence it occurs in residual material above rare-earth metal bearing skarns associated with alkaline intrusive bodies. It occurs with zircon, ilmenorutile, fluorite, phenakite, scheelite, bertrandite, albite, microcline and quartz.

GDiesel. GDiesel is a 100% drop-in alternative Diesel fuel that is manufactured by the Reno, Nevada-based Advanced Refining Concepts (ARC). This new type of Diesel results from an innovative way of combining conventional ultra-low-sulfur Diesel and natural gas— hence the "G" in the name. It burns far cleaner and significantly improves performance, delivering 10 percent or better improvement in fuel economy, depending on the application.

The inventor of GDiesel is Dr. Rudolf W. Gunnerman, who has a 40-year background in the development and marketing of energy- and fuel-related technologies. His last venture, Sulfco, which provided an ultrasound and hydrogen peroxide for efficient desulfurization, and also promised cheaper fuel, wound up bankrupt after many years of positive press releases that success was just around the corner. His son Peter is the partner and director of Advanced Refining Concepts. The firm's ClearRefining process is relatively simple, beginning with the standard ultra-low sulfur Diesel fuel that one would buy at any filling station. This feedstock is first pressurized in a steel tank to less than 10 pounds per square inch (69 kPa), and heated to about , much lower levels than those required during typical refinery processes. Natural gas, the same material used for cooking and heating, is piped into the tank of Diesel fuel, and the resulting mixture then swirls up and through a wheel-shaped filter wrapped with four different metal catalysts — cobalt, among others.

In August 2010, GDiesel received formal certification as an "alternative fuel" from the Nevada Division of Environmental Protection.

The fuel is produced at the company's McCarran, Nevada facility, in which natural gas is combined with standard Diesel fuel, and is then circulated through four different metal catalysts.

Previously, the fuel was featured in publications such as Diesel World and Motor Trend.
