Its chemical composition makes it difficult to match the amber to its producers – it is most similar to the resins produced by flowering plants ; however, there are no flowering plant fossils until the Cretaceous, and they were not common until the Upper Cretaceous.

The name is something of a misnomer as in reality, most commercially available enamel paints are significantly softer than either vitreous enamel or stoved synthetic resins, and are totally different in composition ; vitreous enamel is applied as a powder or paste and then fired at high temperature.

Going back over this ground and analyzing the composition of forces which have created the present scene is one of the tasks undertaken by the Center for the Study of Democratic Institutions, in Santa Barbara.

Just because a tree or other object appears in a certain spot is absolutely no reason to place it in the same position in the painting, unless the position serves the design of the whole composition.

`` Speed in painting a picture is valid only when it imparts spontaneity and crispness, but unless the artist has lots of experience so that he can control rapid execution, he would do well to take these first sketches and soberly reorder their design to achieve a unified composition.

he further reasoned that frequent formulas in epic verse indicate oral composition, and assumed the slightly less likely corollary that oral epic is inclined towards the use of formulas.

Even though the bondage of his verse is not so great as the writing poet can manage, it is still great enough for him often to be seriously impeded unless he has aids to facilitate rapid composition.

-- Glycerinated muscle, in the presence of the physiological agent ( ATP ) responsible for delivering energy to the mechanochemically active proteins of muscle, has been shown to undergo a contraction which is highly sensitive both to temperature and to solvent composition in mixtures of alcohols and water.

Thermal conductivity is directly traceable to the material's porous, air-cell construction which effectively traps air or a gas in the maze of minute bubbles which form its composition.

If the photographically realistic continuity of dreams, however bizarre their combinations, denies that it is purely a composition of the brain, it must be compounded from views of diverse realities, although some of them may never be encountered in what we are pleased to call the real life.

A part of the symphonic composition is also featured in As Good as It Gets, released in 1997.

Argon is notable in that its isotopic composition varies greatly between different locations in the solar system.

The effect of angst is achieved by Shostakovich, Mahler and Berg in compositions of wide dynamic range, at times seemingly spinning out of control ( Mahler ), and atonal music using the twelve-tone row method of composition ( Berg, Schoenberg and others ) to create an angst ridden atmosphere of grotesque sound.

The purpose of the composition is to allow complex dialogue scenes to be played out without changes in camera position.

* Closure: composition of two endomorphisms is another endomorphism.

* Associativity: composition of morphisms is always associative.

The composition is jammed by clashing colors, which is unlike what we've seen in the balanced, natural, and dramatic colors of the High Renaissance.

* If M is some set and S denotes the set of all functions from M to M, then the operation of functional composition on S is associative:

In short, composition of maps is always associative.

's No Lark ," and another composition, " Re: Person I Knew " is a tribute to his producer, Orrin Keepnews.

The overall chemical and structural composition is used to divide ambers into five classes.

Amber is a unique preservational mode, preserving otherwise unfossilizable parts of organisms ; as such it is helpful in the reconstruction of ecosystems as well as organisms ; the chemical composition of the resin, however, is of limited utility in reconstructing the phylogenetic affinity of the resin producer.

Historical " bronzes " are highly variable in composition, as most metalworkers probably used whatever scrap was on hand ; the metal of the 12th century English Gloucester Candlestick is bronze containing a mixture of copper, zinc, tin, lead, nickel, iron, antimony, arsenic with an unusually large amount of silver – between 22. 5 % in the base and 5. 76 % in the pan below the candle.

" Her portraits Fanny Travis Cochran, Dorothea and Francesca, and Ernesta and her Little Brother, are fine examples of her skill in painting children ; Ernesta with Nurse, one of a series of essays in luminous white, was a highly original composition, seemingly without precedent.

Thus, for example, if we can obtain a decomposition of into a hierarchical composition of functions such that,,, as shown in the figure at right, this would probably be considered a highly valuable decomposition.

1515, probably based on a drawing by Raphael, and using a composition derived from a Roman sarcophagus, was a highly influential treatment, which made Paris's Phrygian cap an attribute in most later versions.

In 1981, Kathleen Wheeler contrasts the Crewe Manuscript note with the Preface: " Contrasting this relatively factual, literal, and dry account of the circumstances surrounding the birth of the poem with the actual published preface, one illustrates what the latter is not: it is not a literal, dry, factual account of this sort, but a highly literary piece of composition, providing the verse with a certain mystique.

Among the works exhibited were Le Fauconnier's vast composition Les Montagnards attaqués par des ours ( Mountaineers Attacked by Bears ) now at Rhode Island School of Design Museum, Joseph Csaky's Deux Femme, Two Women ( a sculpture now lost ), in addition to the highly abstract paintings by Kupka, Amorpha ( The National Gallery, Prague ), and Picabia, La Source, The Spring ( Museum of Modern Art, New York ).

The fuel grain is typically a mixture of pressed fine powder ( into a solid, hard slug ), with a burn rate that is highly dependent upon exact composition and operating conditions.

Arts included whaikōrero ( oratory ), song composition in multiple genres, dance forms including haka, as well as weaving, highly developed wood carving, and tā moko ( tattoo ).

To keep the batting from shifting, a patchwork or pieced quilt is often quilted by hand or machine using a running stitch in order to outline the individual shapes that make up the pieced top, or the quilting stitches may be random or highly ordered overall patterns that contrast with the patchwork composition.

In addition, the highly anorthositic composition of the lunar crust, as well as the existence of KREEP-rich samples, gave rise to the idea that a large portion of the Moon once was molten, and a giant impact scenario could easily have supplied the energy needed to form such a magma ocean.

Music history, sometimes called historical musicology, is the highly diverse subfield of the broader discipline of musicology that studies the composition.

They are shown that the Music has a point, has a result and effect beyond its composition and singing: it amounts to no less than a highly detailed template commensurate with the entire history – beginning to end – of a material, ‘ physical ’ Universe that could exist inside ‘ time ’.

These functions are highly dependent on its composition, which defines its properties.

Though the school included highly distinct musical personalities ( the styles of Berg and Webern are in fact very different from each other, and from Schoenberg — for example, only the works of Webern conform to the rule stated by Schoenberg that only a single row be used throughout all movements of a composition — while Gerhard and Skalkottas were closely involved with the folk music of their respective countries ) the impression of cohesiveness was enhanced by the literary efforts of some of its members.

Serialism is a method ( Griffiths 2001, 116 ), " highly specialized technique " ( Wörner 1973, 196 ), or " way " ( Whittall 2008, 1 ) of composition.

Contemporary scholarship, while not claiming that this view was entirely false, tends to hold that it was highly exaggerated ; Palestrina was one of many skilled composers working at the time, and the influence of the Council of Trent on musical composition was more limited than at first presumed ( the composers of the Venetian School, for example, ignored it almost entirely, and Palestrina-style composers such as Lassus, working in Munich, were also quite free to write as they pleased ).

* God is highly pleased with the new composition of Heaven, but Memnoch continues to accuse God of not showing concern for the other souls of Sheol.

His most famous composition is a setting of the Crux fidelis, a work that remains highly popular during Lent amongst church choirs.

Duruflé was highly critical of his own composition.

The composition of porcelain is highly variable, but the clay mineral kaolinite is often a raw material.

The composition highly differed from Radiohead's earlier work, as it featured neither guitar, piano, nor drums, but electric piano, drum machine and computer manipulations of Yorke's voice.

Spectral lines are highly atom-specific, and can be used to identify the chemical composition of any medium capable of letting light pass through it ( typically gas is used ).

Thus, the 5 schilling coins went from an aluminium composition to a silver one, a highly unusual event made possible by the substantial improvement of the Austrian economy in the 1950s.
