Preliminary evaluation of fluid chemistry in the East Mesa KGRA (open access)

Preliminary evaluation of fluid chemistry in the East Mesa KGRA

One of the major problems needing consideration when bringing a geothermal field into production is the anticipation and control of mineral precipitation in both the producing formations and production equipment. Prediction of the chemical interactions between natural multicomponent thermal fluids and the minerals comprising a producing formation can be accomplished by the study of equilibrium models approximating the natural system. Models are constructed from theoretically and experimentally derived thermodynamic data for the involved minerals and aqueous species. This equilibrium modeling approach was applied to the rock-water system at the East Mesa geothermal area in the Imperial Valley of California. Results of petrographic and fluid analyses are given.

Darkness after Time's Colours

Access: Use of this item is restricted to the UNT Community
Recording of Denis Smalley's Darkness after Time's Colours. The piece can be looked on as a vocal journey which passes through various 'ordeals' and encounters, hence the title's allusion to the journey down into Classical underworld. The sound material of this piece grew out of live electroacoustic work Pneuma whose five vocalists elaborate a language of air sounds, unvoiced consonants and vocal harmonics, and play talking drums from India and Ghana, tuning forks, Chinese gongs and tam-tam. Many of these sounds formed a starting point for this piece - gong strokes, vocal air sounds, air blown on the skins of drums, rotations around drum skins, unvoiced consonants, and tuning fork pulsations - but have often been altered in shape and substance by electroacoustic transformation. New sounds extend, imitate, and penetrate the source sounds elaborating an ambiguous sound symbolism.

Natural Images

Recording of Hugh Davies's Natural Images. This is the first of two compositions related to the sounds of the animal kingdom (two more are planned), and it was originally composed for a dance group.

Wonders of the Invisible World

Access: Use of this item is restricted to the UNT Community
Recording of David Koblitz's Wonders of the Invisible World. This piece is comprised of five brief, fragmentary sections in which strands of "imaginary musics" shift in and out of time like the half-remembered images of a dream. The work was composed in the Columbia-Princeton Electronic Music Center (New York) during 1976, using both electronic and acoustic sources. Among the latter were viols, "prepared" guitar, sleighbells, brake drums, balaphon and kora (African instruments).

Chile Fertil Provincia...

Access: Use of this item is restricted to the UNT Community
Recording of Gabriel Berncic's "Chile Fertil Provincia..." Electronic and instrumental sounds, recorded and processed onto four tracks, make up an autonomous flow. To this are added percussion, viola, double bass, tumbadoras and voices, these instruments-persons bringing new visions to the ensemble through the free creation of sequences and/or parallel discourses. "Chile fertil provincia" is the opening line in Alonso de Ercilla y Zœ–iga's La Araucana, the long epic poem which was the first to tell of the conquest of this remote West Indies country in Spanish American literature. It is an allegory about the motherland in ancient and recent times: Latin America told through scenes whose chronology does not obey any absolute historical time. Beginning with a futuristic ancestor and passing through different vassalages, a synthesis forms which evokes the oldest of traditions and aspires to be a binding hymn of the peoples. The titles of this staging music are, in order of performance, as follows: The Woods of Our Ancestors and of Those Yet to Come, The Conqueror's Cross of the South, The Piano of the Inquisition, La Moneda del Valle de Yuro, Jail and Disappearance, The Broad Boulevards Will Open Up. This work, revised several times and finally …

Metamorphosis III

Access: Use of this item is restricted to the UNT Community
Recording of John Winiarz's Metamorphosis III. This piece is the last and most concise work from a series begun in 1974. The idea was inspired by an experimental film made by an artist friend in which the beautiful figure of a greyhound dog in flight is transformed into a kaleidoscope of colors and nebulous shapes. An intense aural experience is achieved by a sharp juxtaposition of the humorous and the serious. The piece is composed using a mixture of concrete and electronic material. Tape loops, speed changes, splicing, and filtering techniques were used. Equipment included three stereo tape recorders, a mixer, EMS synthesizer, and a Burwin filter.

Recording of Bohdan Mazurek's Ballada. The title of the work relates above all to the epic character of the musical narrative.

Samarkandko

Access: Use of this item is restricted to the UNT Community
Recording of Peter Tod Lewis's Samarkandko. This piece is a linear construction on five highly contrasted sources. The affective associations of the materials may suggest a dramatic scenario which, though ambiguous, contradictory, subjective, guided the order on event presentations and their manner of juxtaposition. One evolved theory of the work had precisely to do with the use of extreme, and perhaps at first seemingly unrelated, contrast that such materials can, with care and sensitivity, work together in a composition, to see in the end, related, if only now to the whole. Samarkandko was realized in October of 1976 in the Electronic Music Studios of the University of Iowa.

Dance for Sarah

Access: Use of this item is restricted to the UNT Community
Recording of Arthur Kreiger's Dance for Sarah. This piece explores a rich palette of electronic sounds - sounds whose timbral elements are in a constant state of flux in contrast to those which appear in a more steady - state fashion - sounds that utilize the upper registers of the spectrum set against those giving emphasis to the bass tessitura - sounds played in the most delicate pianissimo opposing those of a loud and raucous character. The form of "Dance for Sarah" is a modified ternary structure. The middle section closes with a crashing glissando that is followed by silence. A quiet high-pitched envelope emerges from this silence opening the final section of the piece while creating an aural reference to the beginning gesture of the composition. The final section contains a noisy, flamboyant climax. The energy of this climax is soon spent ant the piece gently fades.
