El Polifemo de Oro was written in 1956 and revised by the composer in 1981. This two-fold investigation clarifies the structure of El Polifemo through careful analysis of the work and its revision, and by Smith Brindle's approach to composition based on his interviews and books. The second aspect is aimed toward the pragmatic performance issues of tempo, articulation, timbre, voice leading, and the other details of execution. Although the work was written according to serial techniques, the presence, in the twelve-note row, of triadic formations (minor triad, dominant seventh, fully-diminished seventh) juxtaposed with many tritone intervals suggests the use of tonal devices, which Smith Brindle does employ to effect tension and relaxation. It is assumed that tonal devices such as leading tones, stepwise movement in the bass, fourth and fifth relationships, and triadic constructions are heard against a traditional contextual basis and are therefore ways of implying resolution. Where tonal devices are not present, other structural components, i.e., rhythm, dynamics, timbre, etc., are examined with regard to their functions in creating or dissipating tension. Following the analysis of each of the four fragments is a discussion of performance implications based on the analysis. Both the analysis and performance aspects are non-prescriptive and are presented in the spirit that there are many other valid interpretations.

The Inner Piedmont (IP) is the Neoacadian migmatitic orogenic core of the southern Appalachians, exhibiting the widest area of high-grade metamorphism; regional upper amphibolite facies with isolated pods of granulite grade metamorphism. Peak P-T conditions in central GA reached 4.0-7.6 kbars and 630-715 ̊ C. The Brindle Creek fault (BCf) separates high-grade metasedimentary rocks of the eastern Tugaloo terrane (Tt) and Cat Square terrane (CSt). The Tt consists of the Neoproterozoic to early Paleozoic(?) Tallulah Falls Formation, Chauga River Formation, and the Mid-Ordovician Poor Mountain Formation, intruded by Early to Middle Ordovician granitoids. The CSt consists of Siluro-Devonian metasedimentary rocks, such as sillimanite-schist, biotite gneiss, amphibolite, and minor calc-silicate, intruded by Acadian-Neoacadian plutons. Original termination of the CSt was mapped by the USGS just south of Athens, GA, against the central Piedmont suture; however, new evidence from aeromagnetic anomalies and detailed geologic mapping revealed that the CSt and BCf extend into central GA. The BCf truncates a suite of curved magnetic anomalies on the aeromagnetic map. The curved anomalies that truncate against the linear feature may represent the Neoacadian deflection of the IP southwestward along the crustally weak Brevard fault zone. Another prominent lineament was identified southeast of the BCf; detailed geologic mapping revealed an additional thrust sheet in the CSt. Mesozoic brittle reactivation of the late Paleozoic dextral Towaliga fault was also identified striking NE-SW through the field area. Multiple episodes of movement were observed in outcrop and at the micro-scale, defined by crosscutting fracture sets. Low temperature quartz mylonite (350-450 ̊ C) may signify continued shearing of the IP into the late Alleghanian orogeny. A felsic plutonic suite extends the length of the field area, consisting of three distinct granitoids: (1) an older biotite-rich megacrystic granite with megacrysts of K-feldspar; (2) a weakly foliated medium to coarse grained inequigranular granodiorite; and (3) a younger non-foliated fine-grained granodiorite. Analysis revealed that granitoids from central GA are similar texturally and petrographically with granitoids from NC’s CSt. Further whole-rock geochemical analysis revealed that these rocks share similar REE, trace element, and tectonic discriminate patterns. The most important point garnered from the trace element and REE patterns in spider diagrams, such as similarities in peaks and troughs, is that they must share either a common parent, process, or contaminant.

This mainly due to lack of studies on the most adapted cultivars, the best rootstock x scion, floral abortion and knowledge about bearing habit of the main cultivars. The objective of this study was to evaluate the bearing habit, growth, production and quality of pear of the cultivars Carrick, Packham's Triumph and William's grafted on different quince rootstocks and Pyrus calleryana. In the first part of the study it was evaluated the bearing habit, in which we assessed the following variables: percentage of vegetative spurs, reproductive spurs, vegetative brindles, reproductive brindles and borses and total number of flower buds. In this first part we obtained the following results: the bearing habit of cultivars (cvs) Carrick, Packham's and William's is influenced by different rootstocks; in all cultivars tested, regardless of the rootstock, in general, there was an inverse relationship between the percentage of vegetative spurs and reproductive spurs; the most significant influence of the rootstock is about reproductive spurs formation of the cultivars evaluated; cultural management in the orchards of cvs. Carrick, Packham's and William's, especially on the pruning operation should be oriented according the rootstock used. In the second part of the study it was evaluated production, growth and quality of fruit through the following variables: plant production (kg plant-1), productive efficiency (kg.m-3), total soluble solids (TSS), expressed in ºbrix, firmness (PF), expressed in kilograms; latter two variables were performed using non-destructive analysis trough NIR-Case (SACM); fruit mass (kg); fruit diameter (mm); trunk diameter (mm) and branch length (cm). According with the results obtained, the cvs. Carrick, Packham's and William's are more efficient when grafted onto the rootstock of quince 'Portugal' and 'MC'; 'Adam's', 'D'Angers' and 'Smyrna'; and 'Champion', respectively; the productive efficiency of cvs. Carrick, Packham's and William's, in general, is inversely proportional to the vigor induced by rootstocks; fruits of cvs. Carrick, Packham's and William's tend to accumulate a larger amount of soluble solids (TSS) when grafted on less vigorous rootstocks. . / A cultura da pereira ainda é pouco expressiva no Brasil, embora existam regiões aptas para seu cultivo, como a Região Sul. Isso é devido principalmente à carência de estudos sobre as cultivares mais adaptadas, as melhores combinações copa x porta-enxerto, abortamento floral e o conhecimento do hábito de frutificação das principais cultivares. Objetivou-se com esse trabalho avaliar o hábito de frutificação, crescimento, produção e qualidade de peras das cultivares Carrick, Packham s Triumph e William s, enxertadas sobre diferentes porta-enxertos de marmeleiro e Pyrus calleryana. Na primeira parte do trabalho avaliou-se o hábito de frutificação, em que foram avaliadas: percentagem de dardos, lamburdas, brindilas vegetativas, brindilas floríferas e de bolsas e número total de gemas floríferas. Dessa primeira parte foram obtidos os seguintes resultados: O hábito de frutificação das cultivares Carrick, Packham s e William s é influenciado pelos diferentes porta-enxertos; em todas as cultivares avaliadas, independente do porta-enxerto, em geral, houve uma relação inversa entre a percentagem de dardos e de lamburdas; a influência mais significativa do porta-enxerto é sobre a formação de lamburdas das cultivares avaliadas; o manejo cultural nos pomares das cvs. Carrick, Packham s e William s, principalmente por ocasião da poda, deve ser orientado em função do porta-enxerto utilizado. Na segunda parte do trabalho foram avaliados a produção, crescimento e qualidade de frutas, através das seguintes variáveis: produção por planta (Kg planta- 1); eficiência produtiva (Kg.m-3); sólidos solúveis totais (SST), expresso em o brix; firmeza de polpa (FP), expressa em kg; Estas duas últimas variáveis foram realizadas através de análise não-destrutiva, com o equipamento NIR-Case (SACMI); massa de frutas (Kg); diâmetro da fruta (mm); diâmetro de tronco (mm) e comprimento de ramos (cm). De acordo com os resultados obtidos, as cvs. Carrick, Packham s e William s são mais eficientes quando enxertadas sobre os porta- enxertos de marmeleiro Portugal e MC ; Adam s , D Angers e Smyrna ; e Champion , respectivamente; a eficiência produtiva das cvs. Carrick, Packham s e William s, em geral, é inversamente proporcional ao vigor induzido pelos porta- enxertos avaliados; frutas das cvs. Carrick, Packham s e William s tendem a acumular uma maior quantidade de sólidos solúveis totais (SST) quando enxertadas sobre porta-enxertos menos vigorosos.
