MON-90. The MON-90 () is a Claymore-shaped, plastic bodied, directional type of anti-personnel mine designed in the Soviet Union. It is designed to wound or kill by fragmentation. The mine is similar in appearance to the MON-50, but is approximately twice the size with a much greater depth.

Design

The MON-90 has an attachment point on the bottom for connecting a special clamp which can be attached to wood, metal etc. but it has no scissor type legs. It has a sight centered on the top which is flanked by two detonator cavities. The mine contains 6.2 kg of RDX (PVV-5A) to propel approximately 2000 steel rod fragments to a lethal range of 90 meters in a 54° arc (60 m wide spread at 90 m range). 

The MON-90 is usually command actuated using a PN manual inductor and an EDP-R electric detonator (ZT non-electric detonator also available). It can also be actuated by a variety of booby trap (BT) switches including:
MUV series pull
MVE-72 electric breakwire
VP13 seismic controller. 

The MON-90 is usually mounted above ground level on the surface or up in a tree to give the greatest dispersion of fragments. It is waterproof and will function effectively from temperatures of +50 to −50 °C. Due to its large size the MON-90 is effective against unarmored vehicles and it may have applications as an anti-helicopter mine. 

It can be located visually or with metal detectors under most field conditions. Depending on its actuation method the MON 90 may be resistant to blast overpressure from explosive breaching systems like the Giant Viper and M58 MICLIC.

Disarming (demining) hazards

The MON-90 is known to be used with the VP13 seismic controller which prevents close approach for any clearance operations. If the mine is encountered with any type of electrical wires running from it, secure both ends of the wire before approaching the mine, because it could be linked to another mine or other booby trap device.

On detonation the mine will normally propel lethal fragmentation to a range of 90 meters. The actual hazard range for these types of mines can be as high as 300 metres based on US Army tests of the M18A1 Claymore (this is directly in front of the mine, fragmentation range and density drop off to 125 meters to the sides and rear of these mines).

Integrated test facility. An integrated test facility (ITF) creates a fictitious entity in a database to process test transactions simultaneously with live input. 

ITF can be used to incorporate test transactions into a normal production run of a system. Its advantage is that periodic testing does not require separate test processes. However, careful planning is necessary, and test data must be isolated from production data. 

Moreover, ITF validates the correct operation of a transaction in an application, but it does not ensure that a system is being operated correctly. Integrated test facility is considered a useful audit tool during an IT audit because it uses the same programs to compare processing using independently calculated data. This involves setting up dummy entities on an application system and processing test or production data against the entity as a means of verifying processing accuracy.

Gottesman–Knill theorem. In quantum computing, the Gottesman–Knill theorem is a theoretical result by Daniel Gottesman and Emanuel Knill that states that stabilizer circuits–circuits that only consist of gates from the normalizer of the qubit Pauli group, also called Clifford group–can be perfectly simulated in polynomial time on a probabilistic classical computer. The Clifford group can be generated solely by using the controlled NOT, Hadamard, and phase gates (CNOT, H and S); and therefore stabilizer circuits can be constructed using only these gates. 

The reason for the speed up of quantum computers compared to classical ones is not yet fully understood. The Gottesman-Knill theorem proves that all quantum algorithms whose speed up relies on entanglement that can be achieved with CNOT and Hadamard gates do not achieve any computational advantage relative classical computers, due to the classical simulability of such algorithms (and the particular types of entangled states they can produce). 

Since the theorem's initial statement, more efficient constructions for simulating such stabilizer (Clifford) circuits have been identified with an implementation.

The Gottesman–Knill theorem was published in a single-author paper by Gottesman, in which he credits Knill with the result, through private communication.

Formal statement
Theorem:  A quantum circuit using only the following elements can be simulated efficiently on a classical computer:
 Preparation of qubits in computational-basis states.
 Clifford gates (generated by the Hadamard gate, controlled NOT gate, and phase gate S ).
 Measurements in the computational basis.

The Gottesman–Knill theorem shows that even some highly entangled states can be simulated efficiently on a classical computer. Several important types of quantum algorithms use only Clifford gates, including the standard algorithms for entanglement distillation and quantum error correction. From a practical point of view, stabilizer circuits on n qubits can be simulated in  time using the graph state formalism.

Rhodolite. Rhodolite is a varietal name for rose-pink to red  mineral pyrope, a species in the garnet group. It was first described from Cowee Valley, Macon County, North Carolina. The name is derived from the Greek "rhodon" for "rose-like", in common with other pink mineral types (such as rhodochrosite, rhodonite). This coloration, and the commonly inclusion-free nature of garnet from this locality, has led to rhodolite being used as a gemstone. Rhodolite like other varietal names is not officially recognized as a mineralogical term, but rather used as an accepted trade name.

Gemmological properties

Mineralogically and chemically, rhodolite garnets are members of the pyrope–almandine solid-solution series, with an approximate bulk garnet composition of Py70Al30.

Rhodolites from different occurrences around the world have been characterized by crystal chemical and absorption spectral analysis showing that besides iron such elements as manganese, chromium and vanadium may effect the colour of rhodolites.

Rhodolite garnets appear as transparent red-pink-purplish gemstones, including all the different colour shades between violet and red. The colors from different rhodolite sources may vary from a lavender pink to raspberry rose or raspberry red and from purplish-violet (grape) to purplish red.

The color of rhodolites, combined with their brilliance, durability, and the accessibility of stones with no visible inclusions have brought about some demand for the stone in the jewelry industry. Rhodolites used in jewelry are generally faceted to make good use of their brilliance, though they also exist in cabochon form.

Some rhodolites will change color from purplish to a hessonite brown when heated to a temperature of . This process cannot be reversed.

Natural sources

Many deposits of economic importance are found in countries that belong to the geological unit of the so called “Mozambique belt”, such as  Kenya, Madagascar, Malawi, Mozambique, Tanzania, etc. Other sources of rhodolites are in Brazil, India (Odisha), Norway, United States and Sri Lanka.

Anton Eduard van Arkel. Anton Eduard van Arkel, (19 November 1893 – 14 March 1976) was a Dutch chemist.

Biography
In the early 1920s Van Arkel, together with Jan Hendrik de Boer, working for Philips NV, developed the Van Arkel–de Boer process for the preparation of pure titanium: the decomposition of the vapor of titanium tetrachloride on an incandescent tungsten filament. This method was later used for other metals, including zirconium and hafnium.

In 1941 he published the Van Arkel–Ketelaar triangle, a diagrammatic method to depict the chemical bonds that would form between elements in the periodic table.

Van Arkel suggested the names "pnictogen" and "pnictide" to refer to chemical elements in group 15 (the nitrogen group or nitrogen family) of the periodic table.

In 1962 Van Arkel became member of the Royal Netherlands Academy of Arts and Sciences.

Van Arkel published at least one textbook, Molecules and Crystals, in 1941 in his native language. In 1949 this work was translated to English.

Metal Mutant. Metal Mutant is a side-scrolling action-adventure game developed and published for MS-DOS, Amiga, and Atari ST by Silmarils and released in 1991. The game allows the player to transform at any time into three different robot forms: Cyborg, Dino, and Tank.

The cover features an illustration by John Bolton.

Plot
The player controls Metal Mutant, the ultimate battle machine, which was sent to the heavily protected high-tech planet Kronox to find and destroy the tyrant AROD 7. On the way to this goal, the player needs to solve puzzles and combat hostile lifeforms and enemy robots.

Gameplay 
Right from the start the player has a possibility to instantly transform into 3 mechanical robots, each possessing unique abilities:

Cyborg
From the start: Jump, Recharge, Trident
Later: Axe, Grappling Hook, Energy Blast

Dino
From the start: Bite, Flame, Flame Tail
Later: Shield, Remote Mechanical Fly, Bionic Eye

Tank
From the start: 360° Laser Gun
Later: Heavy Torpedo, Boss Energy Signature Detector

The only feature that is common to all robots is the Turbomutant, in the last screens of the game. Upgrades are performed either by finding and picking them up as modules, or programming via terminals.

Development
According to an April 1991 issue of The One, Metal Mutant was originally subtitled Clash of the Tin Cans, and is inspired by the wargame board game BattleTech.

At the fan festival Jaguar Connection 2003, Silmarils co-founder Louis-Marie Rocques stated that an Atari Lynx port was developed and completed but the release was cancelled by Atari Corporation.

Reception
The One gave the Amiga version of Metal Mutant an overall score of 85%, beginning their review by stating that "Metal Mutant is initially disappointing: all you do for the first few screens is match appropriate manoeuveres to combat situations and keep plugging away until your enemies are destroyed. If you begin to persevere however, you begin to discover the game's appeal: horrible puzzles, 40 different types of monster to defeat and a variety of weapons and gadgets to acquire." The One calls Metal Mutant a "130-screen test of memory and joystick dexterity" and praises its "good" graphics, further expressing that Metal Mutant has "a host of excellent animation sequences".
