This was largely facilitated by the excellent governance of the Republic ( which acquired the term model republic ) and the compensation from the British for the loss of the diamond rich Griqualand area.

The diamond model consists of six factors:

It attempts to explain the success or failure of a firm within a market and is somewhat analogous to Michael Porter's diamond model, which tries to explain the success and failure of different countries economically.

For instance, sheet diamond or carbon nanotubes could be produced by a chain of non-biological reactions that have been designed using the basic model of biology.

Lockheed built a model called " the Hopeless Diamond ", so-called because it resembled a squat diamond, and looked too hopeless to ever fly.

Seen as the ' gentleman's express ' version of the visually similar VII GSR, the GT-A model was only produced in 2002 and had the following distinguishing interior and exterior specification: GT-A-only diamond cut finish alloy wheels, clear rear light lenses and all-in-one style front headlights ( later used on the Evolution VIII ).

The original model served as a general guideline, and did not explore or account for several aspects of diamond cut:

The semi-divacancy ( impurity-vacancy ) model for a large impurity in diamond ( Ni, Co, Si, S, etc.

And most of all it is not having the only man you could love, whether he drives a bread truck or delivers the mail or checks the berry crates down at the sheds, or owns seventeen oil wells and six diamond mines, for if you are anybody what he is or does makes no difference if he is the one.

The birthstone of April is the diamond, and the birth flower is typically listed as either the Daisy or the Sweet Pea.

* April's birthstone is the diamond, which symbolizes innocence.

Designed by famous yacht designer L. Francis Herreshoff, this is essentially the same pattern as an admiralty anchor, albeit with small diamond shaped flukes or palms.

For substances which have two ( or more ) stable crystalline forms, such as diamond and graphite for carbon, there is a kind of " chemical degeneracy ".

He also introduced the possibility of allotropy in chemical elements when he discovered that diamond is a crystalline form of carbon.

In Western Australia the Argyle diamond mine in the Kimberley ( Western Australia ) is the world's biggest producer of natural diamonds and contributes approximately one-third of the world's natural supply.

The aim is to score runs by hitting a thrown ball with a bat and touching a series of four bases arranged at the corners of a 90-foot diamond.

For example, diamond is highly transparent, while graphite is opaque and black.

Gem quality diamond is used in jewelry, and Industrial diamonds are used in drilling, cutting and polishing tools for machining metals and stone.

In addition to mined diamonds, synthetic diamonds found industrial applications almost immediately after their invention in the 1950s ; another 3 billion carats ( 600 tonnes ) of synthetic diamond is produced annually for industrial use.

The dominant industrial use of diamond is in cutting, drilling, grinding, and polishing.

Garnering much excitement is the possible use of diamond as a semiconductor suitable to build microchips from, or the use of diamond as a heat sink in electronics.

For example, carbon can be found as diamond, which has a tetrahedral structure around each carbon atom ; graphite, which has layers of carbon atoms with a hexagonal structure stacked on top of each other ; graphene, which is a single layer of graphite that is incredibly strong ; fullerenes, which have nearly spherical shapes ; and carbon nanotubes, which are tubes with a hexagonal structure ( even these may differ from each other in electrical properties ).

This mine is a kimberlite pipe, rich in diamonds, and the reducing environment helped produce both elemental chromium and diamond.

For example, diamond and graphite are two crystalline forms of carbon, while amorphous carbon is a noncrystalline form.

For example, diamond is among the hardest substances known, while graphite is so soft that it is used as a lubricant.

CVD of diamond has received a great deal of attention in the materials sciences because it allows many new applications of diamond that had previously been considered too difficult to make economical.

Special gemological techniques have been developed to distinguish natural and synthetic diamonds and diamond simulants.

After nearly losing control to the Phoenix power, the Stepford Cuckoos developed a secondary mutation, in which their hearts turned to diamond and they were able to imprison the piece of the Phoenix Force.

In the novel, a near future vision of our world, nanotechnology has developed precisely to this point, which enables the cheap production of diamond structures.

Cartwright is thought to be the first person to draw a diagram of a diamond shaped baseball field, and the rules of the modern game are based on the Knickerbocker Rules developed by Cartwright and a committee from his club, the Knickerbocker Base Ball Club.

The Tawny Daylily ( Hemerocallis fulva ) Other flower traits that hybridizers developed include height, scent, ruffled edges, contrasting " eyes " in the center of a bloom, and an illusion of glitter which is called " diamond dust.

Diamond, for a long time considered the hardest substance in existence, is actually softer than fullerite and even harder aggregated diamond nanorods, both of which have been synthesised in laboratories but no commercial process has yet been developed.

Electronic applications of synthetic diamond are being developed, including high-power switches at power stations, high-frequency field-effect transistors and light-emitting diodes.

The appearance of synthetic gems on the market created major concerns in the diamond trading business, as a result of which special spectroscopic devices and techniques have been developed to distinguish synthetic and natural diamonds.

He left GE in 1955, and three years later developed a new apparatus for the synthesis of diamond — a tetrahedral press with four anvils — to avoid violating a U. S. Department of Commerce secrecy order on the GE patent applications.

HRD ( Hoge Raad voor de Diamand ) applies objective criteria and uses an automatic measuring device developed in-house to determine whether a diamond meets the stringent Hearts & Arrows standard.

Related tools have been developed with abrasive surfaces, such as diamond abrasives or silicon carbide.

* Radial keratotomy ( RK ), developed by Russian ophtalmologist Svyatoslav Fyodorov in 1974, uses spoke-shaped incisions, always made with a diamond knife, to alter the shape of the cornea and reduce myopia or astigmatism ; this technique is now usually replaced by other methods ( that use excimer laser ).

Advance Nanotech developed a doped diamond dust, whose sharp corners appeared to be an ideal emitter.

He was an unpromising scholar and was apprenticed to Jules Porgès & Cie, the Amsterdam diamond firm where he developed a talent for examining stones.

Several groups have developed diamond cut grading standards.

Measuring the mechanical hardness of materials changed to using a nanoindenter ( usually made of diamond ) and evaluating bulk moduli, and the Brinell, Rockwell, Knoop and Vickers scales have been developed.

Originally designed as a police public order vehicle for both urban and rural operations, the RG-12 has been developed to be used in many roles, including as routine internal security vehicle, military APC, bullion carrier, bulk diamond carrier and security vehicle on gold and platinum mines.

It is one of De Beers ’ six remaining diamond mines in South Africa and the only major diamond mine to be developed in the country during the past 25 years.

In order to best utilize a diamond gemstone's material properties, a number of different diamond cuts have been developed.

The practical history of diamond cuts can be traced back to the Middle Ages, while their theoretical basis was not developed until the turn of the 20th century.

As the diamond trade developed, early diamond grades were introduced by various parties in the diamond trade.
