    • M'zab community, Algeria, North Africa: Its planning and architectural aspects--past, present, and future

      Matter, Fred S.; Solieman, Khalifa Ali, 1950- (The University of Arizona., 1988)
      This thesis is a report of a study of some aspects of the architecture and urban planning of the M'zab Valley communities of southern Algeria, North Africa. The interrelation of physical planning and religious/social structures of the communities of the M'zab Valley are explored. This study was concerned with the following questions: (1) What are the various environmental factors that influence the design values of the M'zabites? (2) To what extent is the distinctive style of architecture in the M'zab due to religion: the Ibadi heritage or Islam in general? (3) How has the M'zab social structure responded to outside influences in recent years? (4) What is the present trend of the M'zab urban communities in architecture and planning?

    • Macerating and Drying Meat Waste for Beneficial Reuse

      Tamimi, Akrum H.; Farrell-Poe, Kathryn L.; Jendrisak, Mark; Waller, Peter M.; Garcia, Samuel R. (The University of Arizona., 2021)
      To increase sustainability and mitigate waste, the meat industry requires new innovative methods of managing offal and meat waste produced at processing facilities. Current methods of meat waste management include rendering, anaerobic digestion, composting, incineration, and landfilling. Rendering, composting, and incineration provide a treatment method and the potential of waste product reuse through by-product formation. Yet, landfilling of waste may provide a more convenient offsite method of disposal for small and very small meat processing facilities. Processing facilities have economic, available footprint, location, and environmental and regulatory limitations when considering offal waste management. To investigate alternatives to common management methods, a proof-of-concept approach of macerating and drying meat waste was tested. Through a series of trial-and-error tests, offal waste was mechanically macerated, diluted, dewatered, and then dried using a low-temperature, belt-type, dehumidification system. Processed material was tested for microbial and nutrient characteristics to identify beneficial reuse potential. Compared with the initial macerated material, dried material had a reduction in total bacteria (73%), E. coli (95%), and moisture content (82%). Additionally, dried material contained a higher concentration of protein (118%), lipid (40%), and ash (430%) due to removal of moisture. With the reduction of microbes and increase in nutrient concentrations, future beneficial reuse applications as a feed or fertilizer can be examined. These results demonstrate the potential of the proposed process as an alternative on-site management method of offal waste with the goal of beneficial reuse.

    • Macrofiber properties of the Bacillus subtilis strain carrying a transposon insertion

      Su, Ling-Ing, 1961- (The University of Arizona., 1990)
      Recently, a new strain of B. subtilis (Bull913) carrying Tn917, a Streptococcus-derived transposon that confers erythromycin and lincomycin resistance, in the host chromosome has been isolated that grows as multistrand helical structures. Bull913 can produce macrofibers whose properties are like another B. subtilis strain FJ7. FJ7 is a lyt-2 mutant produced by chemical mutagenesis which can form macrofibers with twists ranging from right to left handed. Bull913 also has this spectrum of twisted states. Bull913 macrofibers are similar to FJ7 but are longer lived than FJ7. The Macrofiber properties of Bull913 were compared to FJ7 using growth in liquid media supplemented with (NH₄)₂SO₄ or MgSO₄ -- conditions giving LH or RH macrofibers, respectively for FJ7. The autolysin activities and cell walls substrate properties of Bull913 were biochemically analyzed and compared to those of strains 168 and FJ7. Polyacrylamide gel electrophoresis (PAGE) was used to compare the wall proteins from all three strains. Finally, genetic studies of Bull913 were carried out to determine if the defect in Bull913 is in the lyt-1, lyt-2 or lyt-15 genes, or in a new gene. Both biochemical analysis and genetic studies suggest that Bul1913 carries Tn917 in the lyt-2 gene.

    • The Madrigals of Gioseffo Zarlino (1517-1590): A Descriptive Analysis Of Their Musical Expression and Text Underlay

      McAllister, Peter; Rosenblatt, Jay; Sherrill, Barbara Ellen; McAllister, Peter (The University of Arizona., 2008)
      The Renaissance theorist Gioseffo Zarlino and his theoretical treatise Le istitutioni harmoniche were a vital link to the future of theory. His polyphonic music and ten text underlay rules are representative of the new music of the Venetian School, which was headed by his mentor Adrian Willaert. Examination of Zarlino's thirteen extant madrigals provides us with a direct example of these rules and the secular style of the Venetian School, who strived to elevate their secular works to that of sacred music. The style was inspired by Pietro Bembo's Petrarchan revival, in which Renaissance composers utilized medieval Petrarchan texts or wrote new texts in the Petrarchan style. The texts were set to music which was composed to express the emotions of the texts. Zarlino accomplished this through the selection of major, minor, and diminished sonorities, which began the move to major-minor tonality in the history of Western music.

    • Magmatic evolution and geochemistry of the Piedras Verdes deposit, Sonora, Mexico

      Ruiz, Joaquin; Espinosa Perea, Victor Javier (The University of Arizona., 1999)
      Piedras Verdes is a supergene-enriched porphyry-copper deposit. It contains 290 Mt at a total copper grade of 0.37%. The average thickness of the chalcocite blanket is 110 m. It is 400-500 m wide in a north-south direction and approximately 4 km long. The oxide-sulfide interface ranges from 80 m to 340 m in depth. The country rocks are a Triassic-Jurassic or Paleozoic meta-sedimentary sequence and a Tertiary intrusive porphyry suite. Geochemical studies define six principal intrusive phases of volcanic arc affinity, from quartz monzodiorite to granodiorite in composition. The first magmatic event at Piedras Verdes, was the emplacement of the Sinaloa-Sonora batholith at 67.3 ± 1.4 Ma. This was followed by the emplacement of quartz monzodiorite, "tall" biotite granodiorite, quartz-feldspar and biotite-hornblende granodiorite porphyries, fractionated from a less evolved magma than the preceding batholith. The latest magmatic activity at Piedras Verdes originated andesitic dikes (48.4 ± 1.2 Ma). Mineragraphic studies indicate three mineralizing pulses. A first pulse, related to emplacement of the batholith and the quartz monzodiorite, produced skarns. The second event was associated with the "tall" biotite granodiorite porphyry, introducing sulfides. The third pulse, related to the quartz-feldspar porphyry introduced quartz-molybdenite-chalcopyrite veins. Neodymium isotopic analyses, indicate that the four main intrusive phases at Piedras Verdes were formed by a mixture of primitive and crustal materials. Re-Os isotopic analyses on sulfides yield no considerable amount of Re. It is assumed that the sulfides suffered Re loss during alteration after primary mineralization.

    • Maintenance of Taino traditions within Puerto Rican culture

      Holm, Tom; Ramos, Toni-Ann, 1964- (The University of Arizona., 1995)
      Puerto Rican people and culture are the result of the often violent contact between the colonizing forces of Spain, the African people they later enslaved and the indigenous population of the island. Over time, the blending of these three diverse peoples, each with their own unique culture and traditions, resulted in a new population currently known as Puerto Rican. Little information is available, however, regarding Taino culture and society prior to European contact, and even less is known about their ongoing contributions to Puerto Rican culture. This thesis brings together accurate information about the indigenous people of Boriquen. It attempts to correct distortions and untruths about Taino culture, providing alternative interpretations and giving recognition to the Taino legacy which remains a part of Puerto Rican culture today.
