Parallel and AllegoryKeller, Kody 03 July 2014 (has links) (PDF)
Parallel and Allegory is a series of four pieces that look deeper into specific Christian beliefs. Most directly addressed those that dealt with specific parallels and allegorical relationships. Specific symbols such as nails, hammers, wood, trees, people, fruit, a cup, knife a rope and a stone were the focus of the pieces in the exhibition. Four combinations of these symbols were created to create dialogue and introspection.

Pythagoras at the smithy : science and rhetoric from antiquity to the early modern periodTang, Andy chi-chung 07 November 2014 (has links)
It has been said that Pythagoras discovered the perfect musical intervals by chance when he heard sounds of hammers striking an anvil at a nearby smithy. The sounds corresponded to the same intervals Pythagoras had been studying. He experimented with various instruments and apparatus to confirm what he heard. Math, and in particular, numbers are connected to music, he concluded. The discovery of musical intervals and the icon of the musical blacksmith have been familiar tropes in history, referenced in literary, musical, and visual arts. Countless authors since Antiquity have written about the story of the discovery, most often found in theoretical texts about music. However, modern scholarship has judged the narrative as a myth and a fabrication. Its refutation of the story is peculiar because modern scholarship has failed to disprove the nature of Pythagoras’s discovery with valid physical explanations. This report examines the structural elements of the story and traces its evolution since Antiquity to the early modern period to explain how an author interprets the narrative and why modern scholarship has deemed it a legend. The case studies of Nicomachus of Gerasa, Claudius Ptolemy, Boethius, and Marin Mersenne reveal not only how the story about Pythagoras’s discovery functions for each author, but also how the alterations in each version uncover an author’s views on music. / text

Previous issue date: 2015-07-31 / O desgaste prematuro de conjuntos e componentes industriais, bem como de uma infinidade de outros segmentos, representa um grande fator para a redução da eficiência operacional de um equipamento, provocando assim, um aumento das perdas, e consequentemente, em altas despesas com manutenção e reposição de componentes mecânicos. Este trabalho aborda uma análise comparativa entre a resistência ao desgaste de martelos trituradores de baterias recuperados por três ligas a base de cobalto (Stellite 1, 6 e 21), bem como dois processos de deposição: os processos ao Arco Elétrico com Eletrodo Revestido (SMAW) e ao Arco Plasma Transferido com adição de Pó (PTA-P). Os martelos trituradores são originalmente confeccionados em aço inoxidável AISI 316 L sem nenhum recobrimento. Além da avaliação da resistência ao desgaste no próprio meio de trabalho foram realizados ensaios de microdureza, análises microestruturais via microscopia ótica, e eletrônica de varredura e, análise de diluição com o objetivo de caracterizar e consolidar a pesquisa para que se tenha o estudo comparativo da melhor liga e melhor processo de deposição. Os resultados demostraram que a melhor condição testada foi aquela que empregou a liga Stellite 6 depositadas pelo processo PTA-P. Essa condição apresentou a menor perda de massa nos ensaios de resistência ao desgaste, enquanto que a condição menos favorável foi verificada para os depósitos executados com a liga Stellite 1 utilizando o mesmo processo de deposição. A diluição média das ligas depositadas pelo processo SMAW foi 3,7 vezes maior do que a média apresentada utilizando o processo PTA-P. Os maiores valores de microdureza foram aqueles apresentados pelo revestimento executados com a liga Stellite 1 com maior teor de C, e esta liga, proporcionou um maior número de destacamento dos revestimentos. A microestrutura dos depósitos executados pelo processo PTA-P apresentou-se mais refinada quando comparada com aquelas depositadas pelo processo SMAW. / The premature wear sets and industrial components, as well as many of other segments, is a big factor for reducing operational efficiency of equipment, thus causing an increase in losses, and consequently in high cost of maintenance and replacement of mechanical components. This work presents a comparative analysis of the wear resistance of AISI 316 L steel automotive batteries crushers hammers repaired by welding process using three cobalt-based alloys: Stellite 1, 6 and 21, as well as, two welding deposition process: Shielded Metal Arc Welding (SMAW) and Plasma Transferred Arc with addition powder (PTA-P). Crushers hammers are originally made of stainless steel AISI 316 L with no coating. Besides the “in situ” wear resistance evaluation microhardness tests, microstructure and dilution analysis by optical microscopy and scanning electron were done to characterize and consolidate research in order to have a comparative study of best league and better deposition process. The results showed that the best alloy was Stellite 6 using the PTA-P process, which had the lowest mass loss in wear resistance tests, while the less favorable condition was for deposits made with the alloy Stellite 1 using the same deposition welding process. The average dilution of the alloys deposited by the SMAW process was 3.7 times higher than the average using the PTA-P process. The highest microhardness values were presented by Stellite 1 alloy deposit, with higher C content, which also provided a greater number of coating detachment. The deposits made by the process PTAP showed a more refined microstructure when compared to those deposited by the SMAW process
