| However, the quality and size of the crystals that were produced by these early efforts were poor. |
|
| Some of these crystals contain forms of uranium and thorium that radioactively decay to other elements. |
|
| Researchers who must control the growth of ice crystals in foods should take a look at antifreeze proteins. |
|
| The crystals then promote further degradation of the cartilage matrix through tophus formation and inflammation. |
|
| The crystals were separated and the mother liquor of the above reaction was diluted with the dry ether and it was saturated with dry HCl gas. |
|
| Skeletal feldspar grains contain ankerite rhombs, and tiny sphalerite, galena, barite, and siderite crystals. |
|
| Clinical, radiological and laboratory criteria are helpful in the absence of MSU crystals in the aspirated joint fluid or tophus. |
|
| The gene code for the new blood crystals is now inherent in all races on the planet, but it has not yet become actualized in most people. |
|
| Such a shish-kebab-like crystal morphology is often called shish-kebab crystals. |
|
| Where joints are closely spaced, the large crystals in the granite readily disintegrate to form a sandy regolith known locally as growan. |
|
| The general area contains the common accessory mineral magnetite and crystals of zircon up to 15 carats in size. |
|
| Earlier crystals originated at a time when most of the rock was still liquid and are more or less perfect. |
|
|
|
| Rossi L, Sacannab S and KP Velikov Cholesteric colloidal liquid crystals from phytosterol rod-like particles. |
|
| The first crystals were found in a pegmatite found near Rumford, Maine, USA and in Minas Gerais, Brazil. |
|
| Because their crystals are of the rough equal size, these rocks are said to be equigranular. |
|
| As heat dissipation is slow, and as the rock is under pressure, crystals form, and no vitreous rapidly chilled matter is present. |
|
| This is as the magma cools underground, and while cooling may be fast or slow, cooling is slower than on the surface, so larger crystals grow. |
|
| Intrusive rocks are characterized by large crystal sizes, and as the individual crystals are visible, the rock is called phaneritic. |
|
| The frequent presence of rounded corroded quartz crystals, such as occur in rhyolitic lavas, helps to demonstrate their real nature. |
|
| Good crystals of augite and olivine are also to be obtained in the ash beds of Vesuvius and of many other volcanoes, ancient and modern. |
|
| They may be of considerable size like the grey, rounded leucite crystals found on the sides of Vesuvius. |
|
| A quartz geode is such a situation where the void is approximately spherical in shape, lined with a bed of crystals pointing inward. |
|
| If the lava within the crater has been at such a temperature that solidification has commenced, crystals are usually present. |
|
| The crystal size at the centre of a lava will in general be greater than at the margins, as the crystals have more time to grow. |
|
| The centre of a lava flow is commonly massive and crystalline, flow banded or layered, with microscopic groundmass crystals. |
|
| David Friedrich Wiser amassed a collection of 8000 crystals that he studied and documented. |
|
| Leonhard Euler studied the shapes of crystals, and by the 19th century crystal hunting was common in Alpine regions. |
|
| Alpine crystals have been studied and collected for hundreds of years, and began to be classified in the 18th century. |
|
| He also visited Naples and Mount Vesuvius, where he collected samples of crystals. |
|
| However, doubly terminated crystals do occur where they develop freely without attachment, for instance within gypsum. |
|
| Calcium oxalate crystals in urine are pleomorphic, variegated, and birefringent when viewed through polarized light. |
|
| New materials were used in art, such as amber, crystals found in rock, quartz and jasper. |
