These two polymorphs differ by a " kinking " of bonds ; this change in structure gives β-quartz greater symmetry than α-quartz, and they are thus also called high quartz ( β ) and low quartz ( α ).

These illiterate boors conscripted from villages all across the Czarina's empire had, Suvorov may have told Lewis, just two things a commander could count on: physical fitness and personal courage.

These new poems have only a few direct references to jazz and jazz musicians, but they show changes in Patchen's approach to his poetry, for he has tried to enter into and understand the emotional attitude of the jazz musician.

These have never gone out of style in Scandinavian homes and now seem to be reappearing here and there in shops which specialize in handicrafts.

These gentlemen already have done the party harm by their seeming reluctance to vote aid for the depressed areas and by their criticism of Mr. Kennedy for talking about a recession and unemployment.

These proposals would reduce the amount of tax that DuPont stockholders might have to pay -- from an estimated 1.1 billion dollars under present law to as little as 192 million dollars.

These arrangements would have been impossible if the business community was truly interested in the welfare of its employes.

These forty-seven special purpose governments have the authority to levy taxes, to borrow money, own property, sue and be sued, and in general to exercise normal corporate powers.

These registries are sponsored by 18 national medical, dental, and veterinary societies and have as their mission the assembling of selected cases of interest to military medicine and of establishing through the mechanism of follow-up of living patients the natural history of various diseases of military-medical importance.

These thermometers have now been sent to the United Kingdom for calibration at the National Physical Laboratory.

These provisions are designed to reflect the differences in wealth and population among the States, with the objective that a vocationally handicapped person have access to needed services regardless of whether he resides in a State with a low or high per capita income or a sparsely or thickly populated State.

These could be costly and have a serious effect both at home and abroad.

These destructive forces also have a seriously adverse effect upon the watersheds and their life-supporting waterflows, and upon the other renewable forest resources.

These specialists, I learned, have done a great deal of work to improve the size and health of the plants and the resulting flowers.

These engines have a cylinder diameter of 3-7/8 inches and a stroke length of 3 inches.

`` These recent steps do not offer the possibility of extension to the great number of senior engineers who have displayed technical competence.

These have to do with property rights, municipal official attitudes and a host of others.

These vehicles, with large sensitive areas, have collected data for long enough times to give reliable impact rates for the periods of exposure.

These dosages could have been increased by increasing the source strength which was small in this case.

These have been labeled Regions 1, 2, and 4, respectively, in Fig. 1.

These drugs have no effect on the iodide concentrating mechanism, but they inhibit organification.

These groups have varied widely from mere families, primitive, totemic groups, and small modern cults and sects, to the memberships of great denominations, and great, widely dispersed world religions.

These things have been disseminated by other means, but always in the wake of extensive publication of analytic results.

These children have been described as those who were trying to say something to adults who did not understand.

These have an upper-middle-class leadership and a middle-class membership, with rare exceptions, where working-class parents are active in local P.-T.A. matters.

These must have been for local calls strictly, as in May 1900 the `` only long distance telephone '' in town was transferred from C. B. Carleton's to Young's shoe store.

These are grouped into sections according to the crystal system, and within each section compounds are arranged in the same order as in Groth's Chemische Krystallographie.

These are arranged according to crystal system.

These intermetallic alloys appear homogeneous in crystal structure, but tend to behave heterogeneous, becoming hard and somewhat brittle.

These are grouped into 7 crystal systems, such as cubic crystal system ( where the crystals may form cubes or rectangular boxes, such as halite shown at right ) or hexagonal crystal system ( where the crystals may form hexagons, such as ordinary water ice ).

These shape characteristics are not necessary for a crystal — a crystal is scientifically defined by its microscopic atomic arrangement, not its macroscopic shape — but the characteristic macroscopic shape is often present and easy to see.

These are next diffracted by a standardized salt crystal, with angular results read out as photographic lines by the exposure of an X-ray film fixed at the outside the vacuum tube at a known distance.

These changes can be observed and attributed to various phase transitions, such as key liquid crystal transitions.

These liquid crystal membrane phases can also host important proteins such as receptors freely " floating " inside, or partly outside, the membrane, e. g. CCT.

These weakly bound electrons can move about in the crystal lattice relatively freely and can facilitate conduction in the presence of an electric field.

These " cages " are unstable when empty, collapsing into conventional ice crystal structure, but they are stabilised by the inclusion of the gas molecule within them.

These are both silica minerals, but they differ in that quartz has a trigonal crystal structure, while moganite is monoclinic.

* Genus cirrus ( Ci ): These are mostly fibrous wisps of delicate white cirriform ice crystal cloud that show up clearly against the blue sky.

These high density planes have an influence on the behavior of the crystal as follows:

These processes include the scattering of phonons by crystal defects, or the scattering from the surface of the crystal in case of high quality single crystal.

These include: casting, faceting, carving, jewellery, mosaics ( e. g. little slices of opal on potch, obsidian or another black stone and with a clear dome ( glass or crystal quartz ) on top.

These axes can be determined from the appearance of a crystal in a conoscopic interference pattern.

These strengths vary with the hardness of the snow, type of snow crystal, the number of bonds per unit volume, and the strength of contact interfaces between the layers.

These are serial photos out of a movie ; note differences in crystal locations.

These and other glass pieces probably represented cheaper versions of vessels of carved rock crystal ( clear quartz ), themselves influenced by earlier glass vessels, and there is some evidence that at this period glass and hardstone cutting were regarded as the same craft.

These include photonic crystals, photonic crystal fibers and metamaterials.
