These are composed of strontium sulfate crystals, which do not fossilize, and take the form of either ten diametric or twenty radial spines.

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 include fracture patterns in crystals of quartz and feldspar, and formation of high-pressure materials such as diamond, derived from graphite and other carbon compounds, or stishovite and coesite, varieties of shocked quartz.

These dislocations permit ionic transport through crystals leading to electrochemical reactions.

These structures resemble a heavy coating of hoar frost with big and interlocking crystals, usually needle-shaped.

These ice beers are brewed and filtered at sub-freezing temperatures, thus producing ice crystals and raising the resulting alcohol content.

These anisotropic self-assembled nano-structures can then order themselves in much the same way as thermotropic liquid crystals do, forming large-scale versions of all the thermotropic phases ( such as a nematic phase of rod-shaped micelles ).

These liquid crystals phases may be ferroelectric or anti-ferroelectric, both of which are of interest for applications.

These crystals are not toxic, but create a " gritty " texture in the syrup if not filtered out.

These regions are known as crystals.

These crystals are typically sphenoid in habit and are often twinned.

These are usually observed much closer to the light source than halos, and are caused by very fine particles, like water droplets, ice crystals, or smoke particles in a hazy sky.

These clouds only form glories when the constituent ice crystals are aspherical, and researchers suggest that the ice crystals must be between 0. 009 millimeters and 0. 015 millimeters in length.

These clouds are formed from ice crystals, supercooled water droplets, or liquid water droplets.

These clouds are composed of water droplets, except during winter when they are formed of supercolled waterdroplets or ice crystals if the temperature at cloud level is below freezing.

These clouds do not last long, and they tend to change into cirrus because as the water vapor continues to deposit on the ice crystals, they eventually begin to fall, destroying the upward convection.

These crystals are described as being non-reactive to anti-matter when bombarded with high levels of radiation.

These crystals then trigger a local immune-mediated inflammatory reaction, with one of the key proteins in the inflammatory cascade being interleukin 1β.

These kinds of crystals have one or two optical axes.

These water droplets collide with ice crystals to form a soft ice-water mixture called graupel.

These crystals, when tasted, reproduced the ineffable but undeniable flavor he detected in many foods, most especially in seaweed.

These salt crystals expand as they are heated up, exerting pressure on the confining rock.

These were the ones Keith sought out -- the loners, the ones who killed for the joy of it, like himself.

These were the last words he ever uttered.

These two were going to be easy pickins.

These performances were being staged at historical monuments throughout Europe.

These were Oneida Indians.

These conceptions and the manner in which they were transposed into poetry or engendered by poetic form are intrinsic to western life from the time of Aeschylus to that of Shakespeare.

These basic ideas concerning the nature of religion were, Adams believed, some of the major keys to the understanding of history and the movement of society.

These were his public academic activities, domi forisque, in the college and in the university.

These early experiments were evidently not altogether satisfying to Patchen.

These people were not talking much about it, but you, a foreigner, sensed their apprehension and disappointment.

These public efforts were rare because Mr. Rayburn normally did his counseling, persuading and educating long before an issue reached its test on the House floor.

These microfossils indicate the swamp was `` formed during the Lower Cretaceous period when dinosaurs were at their heyday and when the first flowering plants were just appearing.

These were heroes nine feet tall to him ''.

These little songs, however, were sweet nothings from the heart, tender memories of his childhood, little melodies that anyone could hum and that would make one want to weep.

These were the ships of His Majesty's Navy, herding the hulks of the East Indies merchants and the yachts and ketches of the loyalists.

These trumps were more touching than they were anything else, and seemed to imply that the nights were long, her children ungrateful, and her marriage bewilderingly threadbare.

These were selected carefully and included not only detailed clinical information but adequate pathology of value for research and educational purposes.

These amendments to the Vocational Rehabilitation Act were designed to help provide for more specialized rehabilitation facilities, for more sheltered and `` half-way '' workshops, for greater numbers of adequately trained personnel, for more comprehensive services to individuals ( particularly to the homebound and the blind ), and for other administrative improvements to increase the program's overall effectiveness.

These plans, like Du Pont's, contained provisions for passing the vote on Du Pont's General Motors shares on to the ultimate stockholders of Du Pont, Christiana, and Delaware, except that officers and directors of the three companies, their spouses, and other people living in their households, as well as other specified persons, were to be totally disenfranchised.

These curves were derived by an analysis of extensive skywave measurement data.

These were educated men, who, as Mr. Justice Holmes was fond of saying, formed their inductions out of experience under the burden of responsibility.

These boys acknowledged an introduction to anybody by gently pressing one of his hands in both of theirs, while they gazed, misty-eyed with care, into the eyes of the person they were meeting.
